ACU-1000 Operations Manual 1 General Information 1.1 Scope This instruction manual provides the information necessary to install, configure and operate the ACU-1000 Intelligent Interconnect System. 1.2 What Is Interoperability? The ACU-1000 allows existing, disparate communications systems to cross-connect with each other.
ACU-1000 Operations Manual Any individual LIS (as well as the entire wide area system) can be controlled and monitored from any location on the network by a dispatcher using the Raytheon ACU Controller or WAIS Controller software. The Windows-based ACU WAIS Controller provides full system control, from the local level to statewide, or across any distance connected by an IP-based network, allowing interoperability connections to be made between any two (or more) CSAPs by a simple point & click procedure.
ACU-1000 Operations Manual Each interface module takes the audio and control signals of its associated CSAP and converts them to signals that can be understood by the rest of the system.
ACU-1000 Operations Manual • CPM-4 Module: The Control Processor Module receives control commands from the unit’s operator. The commands may be entered via the HSP-2A’s keypad, or (more efficiently) by either the ACU Controller or WAIS Controller programs. The ACU Controller may be connected directly to an individual ACU-1000 or it can monitor and control the unit over an Ethernet network.
ACU-1000 Operations Manual to any active control programs) does the Controller screen show the change in cross-connection configuration. 1.4.1.1 Radio-to-Radio Cross-connection Figure 1-2 shows two different types of radios patched together. Normally a Type A radio can communicate with any other Type A radio that’s “in range, or with a repeater” but the signals from the Type A radios are completely ignored by the Type B radios, and vice-versa.
ACU-1000 Operations Manual Essentially, the information required to create a cross-connection can be broken down into the following: The equipment interfaced to the person talking provides the following information to the ACU-1000: o The person’s speech. (The RX Audio in the figure.) o A control signal that indicates when this person is talking. (The COR signal in the figure.
ACU-1000 Operations Manual 1.4.1.2 Radio-to-Telephone Cross-connections Figure 1-3 Basic Phone Patch Figure 1-3 shows a basic connection between a 4-wire device (such as a radio) and a 2-wire device (such as a telephone line). 2-wire devices carry audio in both directions, simultaneously, on a single pair of wires. An interface (commonly referred to as Phone Patch) is required between these two disparate devices.
ACU-1000 Operations Manual Figure 1-4 Telephone Cross-Connection Within the ACU-1000, the PSTN module performs the 2-wire to 4-wire conversion. For a twoway conversation between a telephone caller and a radio user, the telephone system would be interfaced to a PSTN module. Within the ACU-1000, that PSTN module would be crossconnected to a DSP module, which provides the radio interface.
ACU-1000 Operations Manual 1.4.1.3 Multiple Cross-Connections The ACU-1000 is not limited to one-to-one conversations. Cross-connections can be made that create a large conference call with multiple users. This could include several different radio systems, a caller on a telephone line, a satphone or IDEN user, and a system operator using a dispatch console. All of these different users will be able to converse with each other.
ACU-1000 Operations Manual 1.6.2 Card Cage The chassis is a 19" wide EIA standard rack-mounted Eurocard card cage equipped with a backplane board into which the modules are plugged. The module PC Boards are 100 x 220 mm. The card cage height is 5.25" (3U) tall, 19” wide, with a depth of 11". An AC input module and power transformer assembly is located on a metal panel that is mounted to the backplane.
ACU-1000 Operations Manual 1.6.5 CPM-4 The ACU-1000 Control Processor Module controls the entire chassis via an internal high-speed serial bus; it requests and receives status and information from each module and sends commands to each module. It instructs modules to output their audio to one of the system audio buses.
ACU-1000 Operations Manual 1.6.8 LP-2 Module The Local Phone Module is the interface to the ACU system for 2-wire devices (such as a telephone set), which generate dialing information. This module contains a loop current generator, ring voltage generator, dial and busy tone generators, a DSP hybrid with VOX and a DTMF generator/receiver. The LP-2 is typically used to create a local interface to the system that is located nearby but not directly at the ACU-1000.
ACU-1000 Operations Manual Figure 1-5 ACU Controller Main Screen The figure above shows two cross-connections (nets); the first is made up of the radios interfaced to modules 2 & 7. The second is a three-way conversation between the radios interfaced to modules 4, 6, & 9.
ACU-1000 Operations Manual Readily available help instructions Currently loaded Radio template Settings options grouped with pull-down menus Figure 1-6 Interface Settings Screen The ACU Controller Interface Settings Screens (one for each port, customized per the type of interface module installed) allow quick and easy adjustments of all of the interface setup and optimization parameters discussed in this manual.
ACU-1000 Operations Manual 1.7.2 The WAIS Controller The WAIS Controller software provides an icon-based GUI interface to facilitate the control and monitoring of Wide Area Interoperability Systems. The WAIS Controller has a variety of views that allow its operators to create and dissolve cross-connections that take place within an individual Local Interoperability System as well between local systems over a network. Multiple operators can simultaneously control or monitor a system.
ACU-1000 Operations Manual 1.7.2.1 WAIS Controller Dispatch Capabilities with DSP-3 The new WAIS Controller 2 has an additional capability that uses the PC's sound card to let an operator communicate with system end-users via DSP-3 modules. Any radio interfaced with a DSP-3 is available for direct communication with the Controller and appears, along with any interconnected modules, in a special screen called the Dispatch View (see Figure 1-8 below).
ACU-1000 Operations Manual 1.7.3 NXU-2A The NXU-2A Network Extension Unit is a separate product. It interfaces many types of communications devices (such as radios or dispatch terminals) to an IP-based network. The NXU-2A provides a RoIP link, which includes radio control signals (PTT, COR, RS-232) along with a VoIP audio path. A variety of vocoders can be configured; this allows the VoIP linked to be optimized based on its purpose and the bandwidth available.
ACU-1000 Operations Manual Figure 1-11 shows a range of NXU-2A applications, all interfacing the same network. In the type of system depicted, the WAIS Controller would normally be used to dynamically make and break connections between the various elements. For example, in some situations, the radio in the lower right of the diagram can be connected to the 4-wire console; at other times to any one of the ACU-1000s. Note that an ACU-1000 can have multiple links to the network.
ACU-1000 Operations Manual Figure 1-12 LE-10 Figure 1-13 LE-20 1.7.5 ACU-T The ACU-T is a tactical version of the ACU-1000. It provides the features of the ACU-1000 in a smaller, rugged case designed for quick on-scene deployment. To provide the tactical capability, the unit has a modified version of the HSP-2A module (named the HSP-4A), and does not use the PSM-1A power supply. The ACU-T uses the same control and interface modules as the ACU-T.

ACU-1000 Operations Manual 2.6 AC Power Requirements The ACU-1000 is designed to operate from 115V or 230V, 47 to 63 Hz, single phase AC power source. The unit will meet all of its specifications over a voltage range of +/- 15% from nominal. The AC power consumption is 80 VA typical, 100 VA maximum. The ACU-1000 is a microprocessor-controlled device. As with any such equipment, a very short loss of AC Power can cause operational problems and/or cause the unit to reset.
ACU-1000 Operations Manual 2.7 DC Power Requirements The ACU-1000 will operate on +11 to +15 VDC, and the power supplies will automatically switch over to DC operation if the AC input voltage sags too low. Actual power consumption will depend on the number of interface modules installed. The DC power input characteristic of the unit is essentially constant power, i.e., the input power requirement is constant so the input current varies with the input voltage and number of modules installed.

ACU-1000 Operations Manual 2.10 Local Radio Interface & Optimization There are three major steps to interfacing radios and other four-wire devices to a DSP module: • Connect the communications devices to ACU-1000 rear panel D15 connectors using properly designed interface cables (either purchased from Raytheon JPS or designed/built by the customer). • Optimize each individual interface/ACU extension.
ACU-1000 Operations Manual 2.10.2 Radio Device Set Up Using Applications Notes and Radio Templates The details of interfacing a radio to the ACU-1000 are contained in Application Notes that are specific for each radio or other device. These notes are available on the ACU-1000 Resource CD that is shipped with each ACU-1000; they are also available by downloading the latest ACU Controller Software from the Raytheon Website at: http://www.raytheon.com/capabilities/products/acu1000/index.
ACU-1000 Operations Manual 2.10.2.2 APPLIES TO: Make sure that the Applications Note is the correct one for the radio being interfaced. If you are not sure, recheck the cable list on the Raytheon web site or contact Raytheon Customer Service. If a cable does not exist for a particular radio, then either use the universal cable to make a cable, or request that a new cable be made by contacting Raytheon Customer Service.
ACU-1000 Operations Manual 2.10.2.3 RADIO MODIFICATIONS: Sometimes it’s necessary to make a physical modification to the radio. Usually this is required because needed signals (such as a PTT input or a TX Audio input (MIC Audio) are not available without the change. Sometimes these signals can be made accessible through radio programming changes rather than hardware modifications. The Application Notes always endeavor to provide the easiest possible interface method. 2.10.2.
ACU-1000 Operations Manual 2.10.2.6 CABLE CONNECTIONS: The various cables covered by the Application Notes are listed, as well as the type of RF connector found on the associated radio. 2.10.2.7 DSP JUMPERS: The proper DSP module audio input configuration jumper settings are listed. See 2.12.4 for more information regarding the DSP module audio input configuration. 2.10.2.8 RADIO INTERFACE OPTIMIZATION: This section lists all of the relevant DSP module options settings.
ACU-1000 Operations Manual 2.10.3 Request for Creation of New Cable Designs If a customer would like to request that Raytheon create a new cable design, below is a list of the basic steps in the process. • Contact Customer Service (919) 790-1011 with a request for a new cable design. • Be prepared to furnish the target radio and one other radio (portable or mobile) that can communicate with it. • The target radios must be set up and tuned so that they communicate out of the box.
ACU-1000 Operations Manual 2.10.4 Optimization of Individual ACU-1000 Extensions Once the radio, satellite phone, or other communications device is connected to the ACU-1000 using the proper interface cable, the interface must be optimized to fit the individual communications device (usually a radio) and the circumstances of its use. A flow chart is provided to assist with this task.

(QA1 Yes) Initial Set Up Using Radio Template If you are not sure if the radio and cable are configured per the Raytheon Application Notes, do not click on the Template file to load it.
ACU-1000 Operations Manual If the radio Squelch Type is either COR or VOX, and the channel is noisy, the radio may unsquelch inappropriately due to this RF noise. When the radio is cross-connected to another radio via the ACU-1000 or ACU-T, the cross-connected radio will transmit every time the noisy radio unsquelches. If a radio has a tendency to key on noise, change the Squelch Type to VMR (Voice Modulation Recognition).
ACU-1000 Operations Manual QA5 Ping-Pong Problems? Some radios have a tendency to unsquelch momentarily at the end of each transmission. In an ACU system, when two radios are cross-connected, whenever one radio is unsquelched, the other is keyed. If a cross-connected radio exhibits the momentary unsquelch after TX behavior, the cross-connected radio will inappropriately transmit.
ACU-1000 Operations Manual QA6 Is Noise Reduction Required? [Affects RX Audio Only] The DSP module has a Digital Noise Reduction Mode that can be used to clean up noisy received signal input. This affects noise that is mixed with the speech signals, not RF noise that unsquelches a radio, creating a loud noise burst.

ACU-1000 Operations Manual 2.10.4.2 Flow Chart B Details – Basic Setup DSP Setup With No Templates & No Application Notes QB1 Is a COR Signal Available? The default Squelch Type is VOX because it will function with all radios. However, if a COR (unsquelched) signal line is available, this is usually a better choice. Determine if the radio has an output that will go either high when the radio unsquelches (Active High COR), or low (Active Low COR).
ACU-1000 Operations Manual Set TX Level The proper TX level is required to fully modulate the transmitter, but not over modulate it. Most radios have an audio limiter prior to the transmitter to prevent over modulation. Even with the limiter, some radios will still over modulate and some even shut off the TX signal when the input is too high.

ACU-1000 Operations Manual 2.10.4.4 Operational Test and Final Adjustment This procedure accounts for radio-to radio variations and verifies proper cross-connection operation of the system. It will be necessary to create separate cross-connections of the radio being interfaced with every other radio in the ACU-1000 or ACU-T system, and perform each of the following checks. The associated DSP settings can be varied during the operational test to check for the optimum level.
ACU-1000 Operations Manual Note the default setting of -9 dBm is the maximum allowed into most U.S. and foreign telephone networks at the subscriber end. Some PBXs may only allow -12 dBm. Ensure that the line levels are correct for the network being used and do not exceed maximum allowed levels. • Cross-connect the HSP handset to the PSTN and place a call from the PSTN to the phone number of an associate who will help with the setup. Refer to Section 2.17.3.1, Telephone Line Level.
ACU-1000 Operations Manual 2.12 Hardware Configuration Settings In the ACU-1000, there are two types of system and module configuration settings: Hardware and Programming. Changing physical pots, jumpers, and switches on each module adjust hardware settings.

Refer to Table 2-17 for full list of these system programming items and also to Section 2.16.2 for an explanation of each item. Section 2.17 gives full explanations for each of the system configuration options that may be programmed.
ACU-1000 Operations Manual Note: The System Programming Items at the start of Table 2-17 are system-wide programming commands that do not require the selection of a module. To execute these items, enter the programming mode, but do not select a particular module. 3. Now that a module is selected, begin actual programming. Enter the desired programming command, following the format described in Table 2-18.
ACU-1000 Operations Manual 2.16.2 System Programming Items This section explains system programming items; they are used only to assist in the configuration of other modules via the HSP-2A keypad. 2.16.3 Enter Programming Mode Use the command * 9 9 to enter the programming mode. Once in this mode, the programming of each individual module’s configuration items is possible.

ACU-1000 Operations Manual 2.17 Description of Configuration Items 2.17.1 HSP-2A Configuration Items There are no configuration items for the HSP-2A module. 2.17.2 DSP-2 and Legacy Module DSP-1 and RDI-1 Configuration Items 2.17.2.1 Receive Audio Level (DSP and Legacy Module RDI-1) This configuration item adjusts the audio receive level for a selected DSP-2 or RDI-1. A correct receive level setting is required to ensure proper operation.
ACU-1000 Operations Manual • Determine the proper input level to the connected equipment (output level from the module). It may be necessary to monitor the module’s output audio level at the connected equipment’s input port with an audio voltmeter or other means. • Start with the TX output at its lowest level. • Raise the output level one step at a time until the proper level is reached. 2.17.2.
ACU-1000 Operations Manual There are some circumstances when it’s important that incoming DTMF not be interpreted by the ACU-1000 as control input, but instead must be passed to other equipment. The settings used are different depending on whether the module that’s passing on the DTMF is a PSTN-2 module (which regenerates DTMF) or any other type of module (which do not). 2.17.2.5.
ACU-1000 Operations Manual 2.17.2.6 COR Type, VOX/VMR Threshold, Hangtime, and Audio Delay (DSP Only) The DSP-2 and RDI-1 modules must have positive knowledge an input audio signal is present so they know when to key an associated transmitter. A signal that provides this information is called COR (for Carrier Operated Relay, sometimes referred to as COS Carrier Operated Squelch).
ACU-1000 Operations Manual algorithm functions: threshold, hangtime, and delay (See definitions below). VOX and VMR use the same programming commands to set hangtime and threshold. Note: When VOX is selected, the DSP-2 will default to an audio delay setting of 60 msec and a hangtime setting of 775 msec. Other times may then be set. • VMR- The VMR algorithm is designed to detect speech in a wide range of input audio SNRs.
ACU-1000 Operations Manual reliably detected under most conditions. The VOX detection time is normally just a few tens of milliseconds, so its default delay time is 60 msec. The delays should be kept at the default values unless some system requirement dictates a change, such as the use of slowto-key radios.
ACU-1000 Operations Manual NOTE: TX Audio Delay is available for all DSP-2 modules, but only for DSP-1 modules with revision 2.08 or higher firmware installed. To verify the revision on a DSP-1 module, remove the module and examine the label on the EPROM. The label reads “DSP-1 1096-201XXX” where XXX is the revision number. TX audio delay is available for part numbers 1096-201208 or higher. 2.17.2.
ACU-1000 Operations Manual how long it takes the module to detect a valid signal in receive audio inputs, plus the time the radio requires to switch into the RX mode. Keep the sampling window width as short as possible, because a gap is put into the transmit audio during this time; but not too short or COR sampling will be ineffective because the system does not have sufficient time to respond.
ACU-1000 Operations Manual • F1 Function Tone, 1950 Hz for 40 msec @ 0dB. • Hold Tone, 2175 Hz @ -20dB, mixed with the TX program audio as long as PTT is enabled (also called the “Low Guard Tone”). The levels of the EIA keying tones are expressed relative to the normal TX program audio. When the DSP-2 is set for default TX audio (0 dBm) into a terminated 600 Ohm load, the levels are +10 dBm for the High Guard Tone, 0 dBm for the Function Tone, and –20 dBm for the Low Guard Tone.
ACU-1000 Operations Manual 2.17.2.13 Module Security Level Selection This command sets a module’s security level. Where n is the security level, with the security level set by n defined as: 0 = not secure (no PIN required), 1 = least secure, up to 9 = most secure. 2.17.2.14 DTMF Commands Enable/Disable This configuration item determines whether an ACU-1000 module considers any DTMF characters present in its input audio to be commands meant for that module.
ACU-1000 Operations Manual In the ACU-1000, DTMF detection is performed by the DSP-2 module rather than by the associated receiver. When the DSP-2 receives line audio or speaker audio from an FM receiver (rather than discriminator audio), any received DTMF characters have been inappropriately deemphasized. This incorrect shaping of the frequency response of the DTMF characters impedes proper DTMF detection.
ACU-1000 Operations Manual 2.17.3 PSTN-2 Configuration items 2.17.3.1 Telephone Line Level This configuration item programs the PSTN-2 for different telephone line levels. The selections for n are 0=0 dBm, 1=-3 dBm, 2=-6 dBm, 3=-9 dBm (default), 4=-12 dBm, 5=-15 dBm, 6=-18 dBm, 7=-21 dBm, 8, 9 both= -24 dBm. This command simultaneously sets the telephone send and receive levels. The default setting is -9 dBm, which is the maximum level allowed into U.S.
ACU-1000 Operations Manual 2.17.3.5 DTMF Mute Timer When a module is not in the Data Mode (See Section 3.5.1.9), all DTMF signals detected in the receive audio are interpreted as commands meant for the receiving module. When the DTMF Mute Timer is enabled, these DTMF command signals are “Muted”; that is, they are not passed on to the ACU-1000 internal audio bus to be routed to another module, nor are they sent back out in any module’s TX audio.
ACU-1000 Operations Manual 2.17.3.7 VOX Threshold This command setting determines the sensitivity of the PSTN module VOX. To be sure to avoid missing speech, the factory default setting is Low Threshold, which provides maximum sensitivity. There may be instances where less sensitivity is desired (for example if excessive if background noise is present). The factory default setting is for Low Threshold. 2.17.3.8 VOX Hang Time VOX hang time determines how long the VOX stays active after speech disappears.
ACU-1000 Operations Manual 2.17.3.11 Outgoing Ring Timer The length of time the PSTN module allows the phone being called to ring is set by this configuration item. The selection options are: no ring, a 30 second ring (factory default), a 1 minute ring, or a continuous ring. When set for 30 seconds or one minute, the call will timeout if not answered before the ringing time elapses. If Outgoing Ring is set to “no ring,” no outgoing calls are allowed.
ACU-1000 Operations Manual 2.17.3.15 PSTN-2 Simplified Setup Procedure This is a set of hints to assist in the basic setup of a PSTN module to the phone system it’s connected to. It gives a step-by-step process that lists the steps in the best order to quickly achieve the best results. • Crossconnect the HSP-2A handset to the PSTN and place a call from the PSTN-2 to the phone number of an associate who will help with the setup. Refer to Section 2.17.3.1, Telephone Line Level.
ACU-1000 Operations Manual • Interconnecting multiple active PSTNs together on the same net can sometimes cause hybrid unbalance issues. Please contact the Raytheon factory for further suggestions and guidance if this is required as there are complex tradeoffs required. 2.17.4 LP-2 Configuration items 2.17.4.1 DTMF Mute Timer When a module is not in the Data Mode (See Section 3.5.1.9), all DTMF signals detected in the receive audio are interpreted as commands meant for the receiving module.
ACU-1000 Operations Manual interpreted as control characters intended for other equipment and all DTMF (other than the DTMF sequence that signals the module to return to the command mode) is not interpreted as control commands. See Section 3.5.1.9 for more information about the Command and Data Modes. While in the Data Mode, the DTMF from the local phone is detected by the LP module and relayed via the CPM-4 module to the cross-connected PSTN-2 module as parallel data.
ACU-1000 Operations Manual set in Section 2.17.4.7 as the ACU-1000 attempts to make the connection. If the extension is busy, a busy tone will be heard. The factory default generates the standard US tones, which is currently the only style offered 2.17.4.7 Ring Cadence The cadence of the ring the LP module sends to the associated telephone set is selected by this configuration item. Two styles are offered; the standard US style (factory default), and European style.
ACU-1000 Operations Manual 2.17.4.12 Aux Output Control The standard configuration for the LP module’s AUX-1 output is to change logic state when cross connected. Contact the factory if other configurations are required. 2.17.4.13 Voice Prompt Initiation Delay A delay can be added to the onset of system voice prompts. Different delays can be added to any of the interface modules and to the HSP module. This variable delay is mainly used to compensate for slow-to-react equipment associated with a module.
ACU-1000 Operations Manual DSP-2 4-wire interface modules should be set with the following changes to default: COR – Set for hardwired (COR) active low and no VOX or VMR RX Level – Set for -16 dBm to start TX level – Set for +4 dBm to start. In general, there could be different types of remote interfaces such as microwave, private wire, LE-xx remotes, or large scale communications consoles.
ACU-1000 Operations Manual 3 Operation 3.1 General Just as the ACU-1000 is capable of many different applications, from local, tactical uses to Wide Area Interoperability Systems, the ACU-1000 also has a corresponding variety of available control methods, including: • Local Control via a PC with the ACU Controller cabled directly to the ACU-1000. [Serial or Ethernet control] • Remote Control via ACU Controller (or multiple ACU Controllers) connected via a network.
ACU-1000 Operations Manual 3.2 Operation Via ACU Controller The ACU Controller program for PCs running Windows is the primary method to control a single ACU-1000. The PC can be connected directly to the ACU-1000 by either a CAT5 crossover network cable plugged into the CPM-4 front panel Ethernet Jack, or by an RS-232 cable attached to the ACU-1000 rear panel DB-9 serial port.
ACU-1000 Operations Manual Figure 3-1 ACU Controller Main Screen Note that if several ACU Controllers are controlling an ACU-1000 via a network, all operators will see, on their Main Screens, the changes made by each of the other operators. The Main Screen changes based on the ACU-1000’s response to a request from the ACU Controller, and all ACU Controllers linked to this ACU-1000 over the network receive these responses.
ACU-1000 Operations Manual 3.3 Operation Via WAIS Controller The purpose of the WAIS Controller is to present, in a clear and simple format, the enormous amount of information inherent in a Wide Area Interoperability System and provide the program operator the means to control the system.

ACU-1000 Operations Manual 3.5.1.7 HSP-2A Keypad – Store Connection Table in Memory Use the command * 3 6 to store a table of all current module connections in non-volatile memory. After this has been done, every time power is re-applied to the ACU-1000, these connections will be automatically restored. Note: the ACU-1000 must not be in programming mode when this command is used.
ACU-1000 Operations Manual 3.5.1.10 HSP-2A Keypad – System Reset Feature The System Reset Feature allows the local operator to reset the ACU-1000 to its initial powerup state. This means all current connections will be lost, and the unit will return to any connections stored last by the * 3 6 command. In order to prevent any inadvertent or unauthorized use of this powerful feature, the System Reset Feature can only be used after first being enabled at the HSP-2A keypad.
ACU-1000 Operations Manual 3.6.1.1 Remote DTMF – Make a Connection When the command * n n is detected in the audio input of any interface module, a connection is made between that module and the communications medium at extension n n. For example, if a VHF radio is wired to a DSP-2 module installed at extension #5, the command * 0 5, entered into the keypad of a telephone set associated with an LP-2 module at extension #11, will cross-connect the local phone set to the VHF radio system.
ACU-1000 Operations Manual 3.6.1.5 Remote DTMF – Data / Command Modes When an ACU-1000 interface module detects DTMF in its receive audio, it can either interpret the DTMF tone as a command input (Command Mode) or transmit DTMF via a connected PSTN-2 module so this DTMF can control other equipment (Data Mode). When in the Data mode, the DTMF input is detected and interpreted.
ACU-1000 Operations Manual The ACU-1000 factory default for this feature is disabled. To enable System Reset capability, use the HSP-2A to enter * 9 0 n n, where “n n” is any pair of digits other than 00. The feature is then enabled, and “n n” is the system reset code. If a DSP-2, RDI-1, or PSTN-2 user (who is currently connected to the system) enters the DTMF command * 9 0 n n, the system will be reset. If * 9 0 and any digits other than the system reset code are entered, the system will not be reset.
ACU-1000 Operations Manual 3.6.2.2.2 Exclusive Operation Mode Access is granted only if the PIN security level is equal to the security level of the extension the user is requesting to be connected. A PIN at security level 6 will allow the user to make a connection with an extension set to level 6, but not to any extension with security levels from 1 to 5 or 7 to 9. Access to extensions set to security level 0 does not require PIN numbers. 3.6.2.3 How to Enable PIN Security • Enter “SETUP MODE” * 9 9 .

ACU-1000 Operations Manual 3.6.3 Basic Local HSP-2A & Remote DTMF Operation Scenarios Examples of the operation of the ACU-1000 without using the ACU Controller or WAIS Controller are discussed in the following paragraphs. This means operation through the use of commands entered either via the HSP-2A keypad or the DTMF tones received by a communications system connected to the ACU-1000. The DTMF tones can be generated by a user of this same communications system provided they have a DTMF keypad.
ACU-1000 Operations Manual 2) The ACU-1000 enables the connection between the two radios and issues a voice prompt indicating the connection has been successfully completed. 3) Users A and B are now free to talk. At the end of conversation, either user can terminate the link by entering * #. 4) Note: For nets involving two modules, when either is removed from the net, the net is terminated. For nets involving more than two modules, removal of one user removes only that user.
ACU-1000 Operations Manual 3) Local operator and User A talk. At the end of conversation, either user can terminate the link by entering * #. In links involving more than two modules, all users should terminate the link by using * #. 3.6.3.4 Radio to Local Operator 3.6.3.4.1 Conditions: 1) Hand-held radio User A wants to talk to local operator at the ACU-1000. 3.6.3.4.2 Operation Steps: 1) The Local Operator Extension number is '00', so hand-held radio User A enters * 0 0 on his DTMF keypad.
ACU-1000 Operations Manual Note: If no one answers the telephone, the attempt to connect will be terminated when the set Ringing time expires (Factory default setting is 30 seconds). 3.6.3.6 Local Phone to Radio 3.6.3.6.1 Conditions: 1) Local Phone user wants to talk to hand-held radio User A. 2) User A’s radio is not busy. 3.6.3.6.2 Operation Steps: 1) Local Phone user picks up handset and hears dial tone. User A resides at extension 03, so Local Phone user enters * 0 3.
ACU-1000 Operations Manual 5) Additional parties can be added to the call if required. 6) Any user can terminate his connection to the link by entering * #; all other connections will be maintained. When only two parties remain in the conference call, and either of these users enter * #, the link will be terminated. 3.6.4 Serial Control Though operation of the CPM-4 via its Ethernet Port is recommended, the unit may also be operated by Serial Control (as was the earlier CPM-2 module) and the ACU Controller.
ACU-1000 Operations Manual In systems where only the RS-232 serial port on the rear panel of the ACU-1000 is being used it may be necessary to change the Baud rate. This can be done directly from the ACU-1000 serial port without having to connect the CPM-4 to a network via Ethernet. Changing the Serial Port Baud Rate via the Serial Port If it is necessary to change the CPM-4 serial port baud rate to something other than 115.
ACU-1000 Operations Manual Changing the Chassis Configuration Setting If the CPM-4 is being installed in an Expanded system (a system with more than one chassis) it may be necessary to change the CPM-4 chassis configuration. The CPM-4 chassis configuration may be changed by using a computer with a terminal program such as MTTY or Hyperterminal.

ACU-1000 Operations Manual 4 System Troubleshooting 4.1 System Troubleshooting Overview This section provides some hints to optimization of ACU-1000 setup based on system operation symptoms.
ACU-1000 Operations Manual If the users of one of the radio systems connected to the ACU-1000 regularly miss the initial syllables of messages from all other radio systems (or other interoperability system members, such as dispatchers or telephone users), the DSP-2 associated with the system missing the initial syllables needs to have its TX Audio delay setting increased.
ACU-1000 Operations Manual Figure 4-1 “Shoot” Versus “Don’t Shoot” A: The audio being sent into the Interoperability System by radio #1. Radio #1 is crossconnected to radio #2. B: Radio #2 is an 800 MHz trunked radio with a Channel Acquisition Delay of 350 milliseconds. Therefore, radio #2 won’t start transmitting the audio from radio #1 until 350 ms have past, and the first word of the message is clipped.
ACU-1000 Operations Manual Figure 4-2 shows the potential communication problems that can occur when the necessary delay is not provided, with messages clipped or lost entirely. The vertical lines signify various channel acquisition delays. Without corresponding TX Audio delays, all speech up until the channel is acquired will be clipped off of the beginning of the transmission (which could be an entire short, but vital, message). If the proper TX audio delay is present, no speech is lost.
ACU-1000 Operations Manual 4.3 Missed Syllables Mid-Conversation The most likely causes of missed syllables in mid-conversation are VOX/VMR dropout or COR sampling. If the VOX/VMR hangtime is incorrectly adjusted, the VOX/VMR will momentarily unkey the transmitter and then quickly rekey. The solution is to increase the hangtime to be slightly longer than the speech inter-word time. This is discussed in Section 2.17.2.6. COR sampling requires that PTT be dropped for a period of time every so many seconds.
ACU-1000 Operations Manual Another way to deal with a stuck channel is for a system operator to constantly monitor all system activity and disconnect any offending radios. In practice, this is too much to ask of a busy operator who most likely can only monitor each ongoing cross-connection for short time periods. 4.5 Ping Pong Some radios have a tendency to unsquelch momentarily at the end of each transmission.
ACU-1000 Operations Manual 4.7 Inability of Dispatcher to Gain System Control If all system users have equal priority, the user that transmits first is in control until this person ceases transmitting and gives someone else a chance. It may be beneficial (or absolutely necessary) to give priority to one or two important users. Remember that an Interoperability System is tying together entire radio systems, not just individual radios.
ACU-1000 Operations Manual In Figure 4-3 above, a cross-connection has been made to link radios #1, #3, and #4. At the moment depicted, a portable of the #4 radio system has keyed (TX) first, so its audio is being retransmitted to the #1 and #3 radio systems. The stoplights signify that, until the #4 portable unkeys, only the audio from the #4 radio will be allowed. If the #1 or #3 portables transmit before #4 stops transmitting, their active COR signals will be ignored by the system.
ACU-1000 Operations Manual 4.8 Poor Audio Quality Clear communication is vital during an emergency. This section describes ways to optimize the clarity of spoken messages so that Interoperability System users are heard, heard correctly, and heard the first time, and not asked to repeat themselves. The ACU-1000 has a variety of options to improve audio quality. 4.8.
ACU-1000 Operations Manual In the simple cross-connection depicted in Figure 4-5 the various volume levels to contend with are: • How loud the person using Portable Radio A is talking • The modulation limiting level of the Portable Radio A transmitter • The RX audio output level of System Radio A (less problematic if a line level out is used; more so if the level is controlled by the speaker volume knob) • DSP-2 Module A’s RX audio level setting • DSP-2 Module B’s TX audio level setting • The mod
ACU-1000 Operations Manual • Click “Apply” to save the setting. • Is equalization or frequency shaping required? See Section 2.17.2.15. [Note: If the interface is using speaker audio from the radio, the level will vary depending on the radio’s volume control setting. Set the RX level in the DSP to 0 dBm, and then vary the radio volume level until the proper Signal LED indication is achieved. Note the setting, and keep the volume control at this setting.
ACU-1000 Operations Manual the minimum necessary to pass the information. This type of noise reduction is most effective on purely random noise, such as white or pink noise, and less effective on impulse noises. The noise reduction value allows the amount of noise reduction to be set in ten steps from off to maximum. Increasing the level provides more actual noise reduction, but may give a “surging” quality to the recovered audio depending on its frequency content.
ACU-1000 Operations Manual The DSP-2 module includes an Audio Equalization feature that can either boost or roll off the high end of the RX audio spectrum. This adjustment can compensate for poor RX audio quality. Follow the procedure below to determine the proper Audio Equalization Setting. Audio Equalization Procedure The best way is to listen to the received audio in the HSP handset (not the HSP speaker, unless a high-quality external speaker is connected). • Monitor the RX Audio in the HSP handset.
