PART 4.
4.1 SYSTEM FEATURE DESCRIPTIONS ACCOUNT CODE ENTRY Station users may enter an account code (maximum 12 digits) before hanging up from a call. This account code will appear in the SMDR printout for that call record. Keyset users may enter this code using an account (ACCT) key without interrupting a conversation. Single line telephone users must temporarily interrupt the call by hook-flashing and dialing the feature access code. Account codes can be up to 12 digits long.
AUTO ATTENDANT The SMISC2 card for the DCS 50si includes four ports of auto attendant for simultaneous answering and call processing. Sixteen professionally recorded prompts inform callers of the progress of their calls. Several examples are the following: “I’m sorry. There is no answer”, “That station is busy” and “Invalid number. Please try again”, Two minutes of battery-backed random access memory (RAM) provide up to 48 customer recordings for announcements or greetings.
call in queue at your station. Either the CID name or CID number will show in the display depending on your N/N selection. SAVE CID At any time during an incoming call that provides CID information, you may press the SAVE key. This saves the CID number in the Save Number feature. Pressing the SAVE number redial key will dial the CID number. The system must be using Least Cost Routing (LCR) to dial the saved number.
NUMBER TO NAME TRANSLATION (350) The system provides a translation table for 350 entries. When the CID number is received, the table is searched. When a match is found, the system will display the corresponding name. This will allow users in areas that do not support deluxe Caller ID to provide names for regular callers. CALL FORWARDING This feature allows the user to redirect (forward) incoming calls.
EXTERNAL This feature forwards C.O. calls to an external number via a central office trunk if allowed by class of service. These C.O. calls forward only after the programmable external call forward delay timer expires. TO VOICE MAIL Each station may be programmed to allow or deny the ability to forward intercom calls to voice mail. When denied, valuable message time in the voice mail system can be saved.
CALL WAITING/CAMP-ON Busy stations are notified that a call is waiting (camped-on) when they receive a tone. The tone is repeated at a programmable interval. Keysets receive an off-hook ring signal through the speaker and single line stations receive a tone in the handset. The volume of the camp-on tone can be set by the station user. Camped-on calls follow Forward No Answer if a Forward No Answer destination has been set.
COMPUTER TELEPHONY INTEGRATION (CTI) Computer Telephony Integration (CTI) allows integration between the DCS 50si and a personal computer system (PC) or a local area network (LAN). Caller ID service is required on TAPI and TSAPI inbound call applications that use the CID information to display computer records in conjunction with the presentation of the call to the station on the DCS 50si system. TAPI and TSAPI are described below.
DATA SECURITY Single line extensions used with modems and facsimile machines can be programmed so that they will not receive any system-generated tones that would disrupt data transmissions. In addition, these devices receive DCS C.O. ringing pattern instead of intercom ring pattern. Devices connected to an SLI card receive a disconnect signal upon termination. DATABASE PRINTOUT A copy of the customer database can be obtained by using PCMMC.
DIRECTORY NAMES Each station, station group and C.O. line may be assigned a directory name (maximum 11 characters). In addition, each personal speed dial number, system speed dial number and entry in the DID translation table may be assigned a name (maximum 11 characters). These names are displayed during calls with these ports and in the case of station and speed dial names, can be used to originate calls. See the Dial by Name feature (Station Features).
local telephone company may use E&M tie lines to provide DID service. In this case these tie lines can be programmed to follow the DID translation table. See DID. Translated E & M tie line calls have Day and Night routing capabilities. EXECUTIVE BARGE-IN (OVERRIDE) The feature allows specially programmed stations with a barge-in key to override the automatic privacy of another station or outside trunk. Programming allows bargein with or without a warning tone.
EXTERNAL PAGE INTERFACE The system KSU provides one external page audio output. The addition of an SMISC card will provide a second audio output and three general purpose relays that may be assigned to control paging zones. Multiple relays may be assigned to a page zone. FLASH KEY OPERATION While a user is on an outside line, pressing the FLASH key will flash the central office or PBX. This is used for custom calling features on C.O. lines or in conjunction with CENTREX/PBX operation.
INCOMING/OUTGOING SERVICE Outside lines are available for incoming or outgoing service. Programming allows any outside line to be used for incoming calls only, outgoing calls only or both way service. INDIVIDUAL LINE CONTROL Each station in the system can be individually programmed to allow or deny dialing out as well as allow or deny answering for each outside line.
LIVE SYSTEM PROGRAMMING The system can be programmed from any display keyset or personal computer without interrupting normal system operation. There are three levels of programming: technician, customer and station. The technician level has access to all programs and can allow the customer access to system programs as needed. Technician and customer access are controlled by different security passcodes. Programming from a PC requires the PCMMC program.
MANUAL The operator presses the NIGHT key and then dials a passcode to change day mode to night mode operation. OFF PREMISES EXTENSIONS (OPX) A single line (tip and ring) extension from an SLI card may be connected to telephone company-provided OPX circuits to remote locations. 8SLI cards and KDbSLIs do not support off premises extensions. OPERATOR GROUP The operator group can contain 32 stations to answer incoming calls. Calls to this group can be set for distributed, sequential or unconditional ringing.
PROGRAMMABLE LINE PRIVACY Each outside line can be programmed to ignore the automatic line privacy. This allows up to four other parties to join your conversation by simply pressing the line button. This is similar to 1A2 key telephone operation. PROGRAMMABLE TIMERS There are over 50 programmable system timers to allow each installation to be customized to best fit the end user’s application.
and station. This feature can be used with the soft keys on the display keysets or as a programmable button. STATION HUNT GROUPS (30) System programming allows up to 30 station hunt groups. One of three ring patterns—sequential, distributed and unconditional—is available for each group. Each unconditional group may contain a maximum of 32 stations. A station may be assigned to more than one group. The default directory numbers to call these groups are 501–529.
TOLL RESTRICTION There are 250 allow and 250 deny entries of 11 digits each. Each of these entries can apply to dialing classes B, C, D , E, F and G. Expensive 976, 1-900, 411 and operator-assisted calls, as well as specific area and office codes, can be allowed or denied on a per-class basis. Class A stations have no dialing restrictions and Class H stations cannot make outside calls. Any outside line may be programmed to follow station toll restriction or follow the toll restriction class assigned to it.
MAXIMUM OF FIVE GROUPS The UCD group option allows callers in queue at a UCD group to be temporarily diverted to an announcement device and then placed back in the queue. A wrap-up timer will allow agents to complete paperwork before receiving the next UCD call.
WALKING CLASS OF SERVICE This feature allows users to make calls or use features from a station that is restricted. The users may either use the WCOS feature code or the authorization code feature. Both methods change the class of service to correspond with the station passcode or authorization code that is dialed. After the call is completed, the station returns to its programmed class of service. 4.1.

4.7 CALL STATISTICS CALLS IN QUEUE NOW How many calls are currently in queue. This statistic is a real time statistic and so will not print on a report. ABANDONED CALLS This shows the number of callers that reached the UCD group, but hung up before being answered. A high number probably means that there are not enough agents available and the wait time is too long.
If this number is less than the total calls received by all the agents it is possible that calls were transferred from one agent to another. If this number is more than the total calls received by all the agents it is possible that calls were unanswered by an agent and went to final destination or callers hung up while in queue. This statistic includes: a) Calls answered by agent. b) Calls that are not answered by an agent and go to final destination.
4.8 AGENT STATISTICS LOGGED IN The number of stations programmed in the UCD group and the number of stations that are currently logged in. This statistic is a real time statistic and so will not print on a report. STATUS This screen shows the agents name, extension number and status. The status can be In Group, Out of group or in DND. This statistic is a real time statistic and so will not print on a report. CALLS ANSWERED The total number of calls answered by the agent.
PART 5. GENERAL USER INFORMATION 5.1 RADIO FREQUENCY INTERFERENCE WARNING: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy.
5.3 TELEPHONE COMPANY INTERFACES NOTE: Allowing this equipment to be operated in such a manner as to not provide for proper answer supervision is a violation of part 68 of the FCC’s rules. RINGER EQUIVALENCE (REN) The REN is used to determine the quantity of devices which may be connected to the telephone line. Excessive RENs on the telephone line may result in the devices not ringing in response to an incoming call. In most but not all areas, the sum of the RENs should not exceed 5.0.
DISA WARNING Lines that are used for Direct Inward System Access feature must have the disconnect supervision options provided by the telephone company insist that your service company verify this.
