AirLink Pro 64S Installer’s Guide Installation and System Administration Burst Sync Signal Description The Burst Synchronization signal is used by AirLink Modems in Hub and Repeater applications to synchronize two or more modems to a common reference. Two types of synchronization are required: transmit burst and bit timing synchronization. These two components are necessary to align the transmit bursts, and to ensure that an exact number of user data bits are generated every 8.
AirLink Pro 64S Installer’s Guide Installation and System Administration depicts the format of a single burst, however two such bursts, a transmit and a receive burst, are required to form a complete TDD frame. Each burst is approximately 4 milliseconds long, which is about 40% of the TDD frame time. The two bursts together take up 80% of the frame time, and the unused 20% is called the guard time, which is necessary to allow for the two-way propagation delay between the two modems that form a link.
AirLink Pro 64S Installer’s Guide Installation and System Administration Installing Burst Sync Wiring Burst synchronization minimizes near-end inter-channel interference among the units in a hub configuration; all the hub units are synchronized in order to transmit and receive at the same time. The burst synchronization system is implemented with a dual external bus. Each bus consists of a differential pair of wires, driven by a tri-stateable RS-485-type device.
AirLink Pro 64S Installer’s Guide Installation and System Administration the "Backup Master." All other units at the hub are designated as "Subordinate Master." The burst synchronization signal on the primary bus is provided by the Reference Master unit. When activity is lost on the primary bus, implying that the Reference Master has failed to provide the burst synchronization signal, the modems will use the backup burst synchronization signal provided by the Backup Master unit.

AirLink Pro 64S Installer’s Guide Installation and System Administration Burst Synchronization Compatibility with AirLink One Modems The AirLink Pro 64S uses a burst synchronization signal that is compatible with the signal used in the AirLink One S-band 64kbps, 128kbps, and 256kbps models and AirLink One L-band models. A hub configuration may contain both AirLink Pro and AirLink One units. AirLink One units, however, cannot take advantage of the backup burst synchronization feature.

CHAPTER 3 Configuration This chapter describes how to use the AirLink Pro 64S command line terminal user interface to set and change configuration parameters. The information in this chapter includes descriptions of all the AirLink Pro 64S configuration commands and options, and lists the default configuration settings. Inside this chapter: Overview .................................................................................3-2 Using the ASCII Terminal Interface .................................
AirLink Pro 64S Installer’s Guide Configuration Overview You configure the AirLink Pro 64S by connecting an ASCII terminal or a personal computer to the Terminal port of the AirLink Pro 64S. The AirLink Pro 64S ASCII terminal interface provides a command line interface that consists of a body of commands for manipulating the operation of the AirLink modem. This includes configuring operational parameters, monitoring operation, and responding to alarm conditions.
AirLink Pro 64S Installer’s Guide Configuration Command Line Interface Syntax 1. A command line consists of a basic command keyword. This basic command keyword must be the first word of the command. More specific keywords and operands follow this basic command keyword. For example: AIRLINK PRO 64S> get RSSI 2. Each token (basic keyword, specific keyword, operand) must be separated from another with either an ASCII comma, ASCII space, or ASCII tab.
AirLink Pro 64S Installer’s Guide Configuration 3. When the escape key is struck during the typing of a command line, all characters typed are deleted, and the system is then ready to accept another command. 4. When R is pressed, at the prompt, the previously issued command is displayed. This command can be edited by backspacing to delete characters from the end, and/or by augmenting the command with additional characters.
AirLink Pro 64S Installer’s Guide Configuration type (i.e. space or tab) and the number are not checked. Keywords in parentheses are optional; such words need not be typed for the command to execute. Refer to Appendix D for a complete list of keywords.
AirLink Pro 64S Installer’s Guide Configuration Logout This command is used to exit the system. It should be done when all configuration and setup is completed to prevent unauthorized use of the system. AIRLINK PRO 64S> logout Help This command is a request for the on-line help facility. If the HELP keyword is not followed by any additional parameter, a command summary is displayed. If a specific command follows the HELP keyword, a list of all the possible parameters for the specified command is displayed.
AirLink Pro 64S Installer’s Guide Configuration BOTH For example, if you type SET SITE NAME Sunnyvale at the prompt, the site name is changed to Sunnyvale for the local unit. At the Prompt type AIRLINK PRO 64S> remote Get status to query the status of the remote unit. To configure both ends of the link use the BOTH command. AIRLINK PRO 64S> NOTE both Set pn code 4 REMOTE and BOTH commands apply only to point-to-point configuration.
AirLink Pro 64S Installer’s Guide Configuration Date and Time The date and time are used in system operations as well as to provide a reference in time-stamping status, performance and alarm information.
AirLink Pro 64S Installer’s Guide Configuration Password The password is needed when the unit is powered on, or after the operator logs off the system and wants to enter it again. The operator must provide the correct password to use the GET, SET, RESET, TEST and REMOTE commands. When the unit is prepared for shipment, it is configured with a null password as a default. To gain access to the system the first time, press in response to the log in prompt for the password.
AirLink Pro 64S Installer’s Guide Configuration Application The APPLICATION parameter specifies the role of the unit in a specific system configuration. Figures 3-1 to 3-4 show the various valid configurations. The APPLICATION parameter has the following valid options: 1. Slave Unit in Point-to-Point Link 2. Master Unit in Point-to-Point Link 3. Master Unit at Repeater Site 4. Reference Master Unit at Hub 5. Backup Master Unit at Hub 6. Subordinate Master Unit at Hub 7.
AirLink Pro 64S Installer’s Guide Configuration In a point-to-point link ( See Figure 3-1), where one AirLink Pro 64S modem pair consists of a master unit (Application 2) and a slave unit (Application 1), the master unit provides the burst synchronization signal source for the link when transmitting data. The slave unit synchronizes to this timing reference when it transmits data back to the master unit.
AirLink Pro 64S Installer’s Guide Configuration Figure 3-2 Point-to-Multipoint Application Hub Application (Applications 4, 5, and 6) A hub application is used when two or more full-duplex links emanate from a single centralized location. In a hub configuration, two or more units are colocated at the hub site. One of the units is the synchronizing unit, the Reference Master (Application 4), which generates the burst timing reference for the other units.
AirLink Pro 64S Installer’s Guide Configuration Figure 3-3 Hub Application Repeater (Application 3) When either the range is too great for a single hop installation between master and slave, or line of sight can’t be achieved due to physical obstacles, one solution is to use a repeater configuration. Repeater mode extends the range of remote slave units. As shown in Figure 3-4 , this is accomplished by connecting a slave unit to a master unit in a repeater mode.
AirLink Pro 64S Installer’s Guide Configuration Figure 3-4 AirLink Pro 64S Two Part Repeater Link At a repeater site, there are two modems: the slave modem (Application 1 or Application 8) for the previous hop, and the master modem (Application 3) for the next hop.
AirLink Pro 64S Installer’s Guide Configuration Repeater Variations If other AirLink Pro 64S units are located at the repeater site, the repeater site is treated as a hybrid hub, where the added units are wired to the burst synchronization signal pairs of the slave at the repeater site and synchronize their transmit bursts to the burst synchronization signal from the slave at the repeater site.
AirLink Pro 64S Installer’s Guide Configuration the V.35 and the EIA-530 standards is configurable using the “SET DTE MODE” command. When the unit is powered up for the first time, all three interfaces are disabled. The drivers to each of the two connectors are tri-stated. Before the DTE interface can function, the SET DTE MODE must be issued to select the desired DTE interface standard. A DTE interface protection circuit is included in the AirLink Pro 64S modem.
AirLink Pro 64S Installer’s Guide Configuration Therefore, if the DTE equipment is supplying an RS-232 signal using voltage levels less than 7 volts, the AirLink Pro modem will not operate correctly unless the DTE Protection circuit is disabled. Table 3-1 Voltage Requirements DTE Protect Configuration DTE Interface Voltage Requirements RS-232 on TXD>7.0 or <-7V V.35 on DTR >7.0V or <-7V and on TXD <7.0V or >-7.0V EIA-530 on DTR <7.0V and >-7V and on TXD <7.
AirLink Pro 64S Installer’s Guide Configuration data bits are sampled by a 64 kHz clock in the transmitter, which means that there are at least four samples per bit. The asynchronous bits are then reconstructed on the other side of the link by the receiver. For all asynchronous data applications, if the DTE is providing a clock signal on the TT pin, the command “Set TT Clock Detect Off” should be issued to avoid confusing the AirLink unit’s automatic detection circuit.
AirLink Pro 64S Installer’s Guide Configuration for all the applications are shown in the table below. Although there is not necessarily an exact one-to-one correspondence between AirLink One and AirLink Pro 64S clocking modes, the equivalent clock mode from the AirLink Site Planning Guide that most closely matches is shown in the table. In general, the default values assume that the modem clock will be used by the DTE as a reference to clock out its data.
AirLink Pro 64S Installer’s Guide Configuration be synchronized to a single, stable frequency reference. The various network configurations that AirLink Pro supports require four choices for the phase reference: no reference (the oscillator freeruns), the externally-supplied TT clock from the DTE interface, a clock derived from the received RF signal, and a clock supplied on the burst sync bus.
AirLink Pro 64S Installer’s Guide Configuration where operand is on (to activate the circuit) or o f f (to de-activate the circuit). The system displays auto-detect mode by issuing the following command: AIRLINK PRO 64S>get TT clock detect operand AirLink One Clock Mode Emulation The following sections describe how to set up AirLink Pro 64S modems to emulate AirLink One clock modes. See the AirLink Site Planning Guide for more information on this topic.
AirLink Pro 64S Installer’s Guide Configuration DTE/TT This mode is used when it is desired to synchronize the AirLink Modem to an external reference. Generally, only one modem in a network will be configured in this mode, and the rest will be synchronized to the master oscillator via the RF signal or the burst sync signal.
AirLink Pro 64S Installer’s Guide Configuration modem transmit oscillator acts as the frequency reference, whether it is freerunning or locked to an external reference from the DTE. However, there may be other applications where the transmit and receive data streams need to maintain synchronization with clocks that originate from independent oscillators at either end of a link.
AirLink Pro 64S Installer’s Guide Configuration In order to operate the slave modem with an independent transmit clock that is externally provided by the DTE, issue the following commands at the AirLink prompt: AIRLINK PRO 64S>set tx vcxo tt_clock AIRLINK PRO 64S>set tx clock source external This will change the frequency reference for the transmit oscillator from “Receive_Clock”, which is derived from the received signal, to “TT_Clock”, which arrives via the DTE interface port.
AirLink Pro 64S Installer’s Guide Configuration potential for interference between adjacent links. See the AirLink Site Planning Guide for more information on this topic. PN The AirLink Pro 64S has a set of Pseudo-random noise (PN) codes. No PN code is “better” or “worse” than another. Using a different code helps the AirLink Pro 64S separate the desired incoming signal from undesired signals from other AirLink Pro 64S links.
AirLink Pro 64S Installer’s Guide Configuration RF Plan This command specifies the radio channel plan. The AirLink Pro 64S may be configured for one of the two sets of channels. The values are Channel Plan 1 (Channels 1-15) and Channel Plan 2 (channels 1-20). Channel Plan 1 consists of 15 channels used in a network consisting of both AirLink Pro 64S and AirLink One 64SMP units.
AirLink Pro 64S Installer’s Guide Configuration Alarm Level This parameter sets the severity level for reporting alarms: Status, Minor, and Major. Status messages are the least severe and all events are reported, while the Major messages are the most severe and only fault events are reported. Refer to Tables A-1 to A-3 in Appendix A. Alarm Holdoff This command specifies the amount of time for which an alarm condition must persist before a dialout attempt is made.
AirLink Pro 64S Installer’s Guide Configuration Threshold 1 HR ES This parameter specifies the number of errored seconds (ES) events that must occur in a 1-hour interval before an entry is made into the event queue. One errored second is a 1-second interval in which a CRC-16 error is detected in the data payload. The operand is between 1 and 999.
