INSTALLATION 5. Starting with Cabinet 2 or 3, turn on the power switch on each cabinet [Cabinet 1 must be last). IMPORTANT: If power to Cabinet 1 is not turned cold start initialization may not occur properly. 6. Check to be sure that the cabinet fans are rotating.
INSTALLATION Cold Start the System To ensure that the system recognizes the current position of the CPs, you must cold start the system before beginning initialization. A cold start causes the system to check all slots for valid CP types and assign default translations to ail ports (except auxiliary trunk ports).
INSTALLATION 7. The system will respond with: Action= 8. Enter 20 for a cold start. The system will respond with: Save/Restore: Action=20 Data= 9. Enter D. The system will complete the word Data followed by the = sign. 10. Enter 1 for a cold start or 2 for a limited cold start.
INSTALLATION Cold and warm starts both display the same type of information on the SAT. This consists of a listing of the version of the firmware loaded in the CPU/Memory CP, followed by a configuration listing of all CPs recognized by the system. The CPU/Memory CP is not in the configuration listing; however, it is located in slot 1 of Cabinet 1.
INSTALLATION The SAT message for a cold or warm start appears after the system has performed all self-tests and reading of its configuration. Typical cold start SAT message is as follows. The example is for a 2-cabinet system. Typical Release 3 Version 3 Cold Start Message RESTART TS ROM pair 1:version 3.
INSTALLATION Check Performance of Cabinet Components Each CP has three colored LEDs on the front panel that indicate whether it is functioning properly or not. When a cold start is performed, the system undergoes a series of self-tests and loads default translations.

INSTALLATION INSTALL MODULAR BULK POWER SUPPLY (Optimal) The 346 Modular Bulk Power Supply (MBPS) is a cost-effective and flexible alternative to the KS-2291 1 power supply. The 346 MBPS can be used where the wall-mounted (outlet) KS-2291 1 power supply cannot be used or where multiple KS-2291 1 power supplies are required.
INSTALLATION Tie trunks must be segregated on a separate block because a different splitter cable is used. Also, off-premises stations must be segregated one 700A Jack. The first five trunks in each group of eight (loop start or ground start trunks only) can be connected through an ETU to five power failure transfer stations.
INSTALLATION Connect Cabinets to TAE Blocks The connections between the cabinets and the TAE blocks are made using connectorized splitter cables. Make sure that each trunk group on each connecting block is connected to the correct type of CP and protected with its approved secondary protector (as shown in Table 2-B).
INSTALLATION Connect Tie Trunks A 2:1 connectorized splitter cable, WP90929, L3, is required to connect the 700A Jack to the cabinet for tie trunks. 1.
INSTALLATION Install DS1 DS1 signaling allows a digital connection between the System 25 and other PBXs, Central Offices, Toll Offices, off premise stations, and data end points such as host computers. The TN767 emulates ground start, Ioopstart, tie and DID Trunks in addition to off premises stations.

MAINTENANCE MAINTENANCE The primary maintenance objective is to detect, report, and clear troubles as quickly as possible with minimum disruption to normal service. Periodic system self-tests, automatic software diagnostic programs, and fault detection hardware are several of the maintenance tools used to achieve this objective.
MAINTENANCE EQUIPMENT NEEDED The any maintenance technician System 25 service call: should take the following tools and equipment on EIA breakout box Digital voltmeter (KS-20599 or equivalent) 11 O/66.
MAINTENANCE Precautions Electromagnetic fields radiating from the system cabinets may generate noise in other communications equipment. The technician must be sure that all cabinet panels and covers are securely in place after performing maintenance. Caution: Electrostatic discharge can destroy or severely damage integrated circuits on CPs.
MAINTENANCE GENERAL MAINTENANCE INFORMATION System Errors and Alarms During periodic testing, a maintenance audit could detect a system error that automatically generates an error record.
MAINTENANCE Memory (ZTN81 [RIV7] or ZTN127 [RI V2]J: The red LED on this CP lights when power is applied and goes dark upon successful completion of the ROM checksum test initiated by the Call Processor CP. Failure is indicated by a steadily lighted red LED.
MAINTENANCE Attendant Console LED A lighted green Alarm LED on the console indicates the presence of a Permanent System Alarm. The LED flashes with each new alarm. The attendant can press the associated button to cause the LED to light steadily. A lighted red Alarm LED indicates a barrier code violation.
MAINTENANCE Using RIMS, the remote administrator can initialize translations after the switch itself is installed. As long as there is no hardware change, the remote administrator can do ongoing administration without having to visit the customer’s site.
MAINTENANCE Administration Requirements For a RIMS call to be made during initialization, at least one voice station and one trunk must be translated. A cold start with defaults provides these translations. The RIMS transfer code (*1 00) can be assigned to a Repertory Dialing feature button on a multiline voice terminal.
MAINTENANCE MAINTENANCE STRATEGY Fault isolation is the cornerstone of the System 25 maintenance strategy. Maintenance activity isolates faults to one (or more) repairable or replaceable maintenance units. Equipment should be tested in the following order: 1.
MAINTENANCE SYSTE M TROUBL E REPORTED USER-REPORTED DISCUSS THE TROUBLE WITH SYSTEM USERS CAP ALARM REPORTED CAP ALARMED READ PERMANENT SYSTEM ALARMS TABLE IN ERROR LOG : AND CHEC K CIRCUIT BOARDS AND.
MAINTENANCE Sometimes, faults recorded in the error log and user-reported troubles will exist at the same time. The logged faults should always be cleared first, if possible. This procedure often clears the user-reported troubles without any additional maintenance.
MAINTENANCE Common Control Problems Common Control circuitry is difficult to troubleshoot. The system must be powered down before any of these CPs are replaced. Before powering the system down, save translations to tape (see “Using the Digital Tape Unit”).
MAINTENANCE Station, Wiring, and Trunk Problems If the system indicates that a fault is with a station, or if a user complaint indicates a station problem, the trouble must be isolated to the station itself or to the wiring between the cabinet or station interconnect panel and the station.
MAINTENANCE USING THE DIGITAL TAPE UNIT The Model DC4 Digital Tape Unit (DTU) or equivalent is extremely important in system maintenance. System Translations are stored in the DTU and can be accessed in the unlikely event that translations are lost during a system failure .
4. Press the REWIND button, and wait for the unit to tape. This step ensures that the tape is played from Note: The system automatically compensates for “leader” material at the beginning and end of the Saving Translations Follow these steps to save 1.
MAINTENANCE 9. 10. Press c to continue, and the tape unit is automatically started by the system. Saving translations on tape takes about 5 minutes and does not affect switch performance. When the save is complete, the unit stops automatically. If the save is successful, the SAT displays: SAVE COMPLETED SUCCESSFULLY.
MAINTENANCE 5. 6. 7. . 8. 9. 10. Enter 2. The system responds with: Save/Restore: Action=2 Data=. Enter D. The system completes the word Data followed by the = sign.
MAINTENANCE Restoring Translations Note : Restoring translations from tape removes the system from operation for about 5 minutes. When it is necessary to restore system translations from tape, follow these steps: 1. 2. 3. 4. 5. 6. 7. Complete the steps under “Setting up the DTU,” using the cassette on which translations were saved.
MAINTENANCE 8. 9. 10. 11. Press c for continue, and the tape unit is automatically started by the system. Restoring translations takes about 5 minutes.
MAINTENANCE ROUTINE MAINTENANCE The following are general trouble-clearing techniques usually required to resolve system-detected and/or user-detected troubles. ● Reseating and Replacing Circuit Packs ● Removing and Restoring Power ● Restarting the System.
MAINTENANCE 6. Inspect the cabinet backplane and the connectors at the back of the CP. It may be possible to clean dirty connectors per prescribed procedures and return the CP to service. However, if any connectors are damaged or corroded the CP should be replaced.
MAINTENANCE Removing and Restoring Power When the following procedures are performed, the system must be unplugged from the ac power source: ● ● ● ● Reseating or replacing the Service Circuit .
MAINTENANCE Restarting the System The system automatically warm starts after power is restored. (The system’s maintenance software may restart the system under certain self-detected error conditions.
MAINTENANCE 6. 7. 8. 9. Enter 9 (for the SAVE/RESTORE selection) and press <RETURN>. The system responds with: Action = Enter 10 for a warm restart. The system responds with: Save/Restore: Action=10 Data=. Enter D. The system responds with: Data = 10.
MAINTENANCE Messages displayed on the SAT indicate which restart is being performed. The same type of information is displayed for a cold and a warm restart. This information consists of a listing of the version of the firmware loaded in the CPU/Memory CP and a configuration The CPU/Memory CP is not listed in be located in slot 1 of Cabinet 1.
MAINTENANCE The SAT message for a cold restart appears after the system has performed all self-tests and reading of its configuration. The time required for a cold start depends on the number of CPs in the system but is generally several minutes.
MAINTENANCE ERROR LOG When a system maintenance object fails periodic testing, the system automatically generates an error record. Depending on severity, the record is stored in one of three tables in the Error Log.
MAINTENANCE A typical error record from the Permanent System Alarms and Transient System Errors table is as follows: PERMANENT SYSTEM ALARMS PORT BOARD FIRST LAS T COUNT NAME NUMBER CODE OCCURRED OCCU.
MAINTENANCE Error records in the Most Recent System Errors table have a slightly different format. A typical error record from the Most Recent System Errors table is MOST RECENT SYSTEM ERRORS POR T BO.
MAINTENANCE The Error Log is under the control of internal background maintenance software that automatically escalates an error to a more serious category or retires it. The system tests itself after a repair has been made. If the error condition is corrected, the error may be removed from the Error Log.
MAINTENANCE 9. 10. 11. 12. . If you Enter 1 and press <RETURN>. The SAT displays: SEARCHES: ACTlON=1 DATA= Enter D. The system completes the word Data followed by the = sign.
MAINTENANCE ERROR MESSAGES Error messages, along with the alarm indicators, are the most likely indicators that an error has occurred in the system. When a maintenance object fails periodic testing, the system automatically generates an error record. The error record (log) is accessible through the SAT.

MAINTENANCE Clearing System-Detected Troubles Most troubles are detected through the Alarm LED located on the Attendant Console, the Error Log, and, in some cases, the LEDs on the circuit packs (CPs). The following is a list of system troubles. Each item in the list is described in this section.
MAINTENANCE Failure of the CPU/Memory CP at power-up generates the following type of error message: FAIL: <CARD>: <TEST>: <DETAIL>: The bracketed fields contain the following informa.
MAINTENANCE After total failure, the system ceases to operate and the green LED on the CPU/Memory CP may not flash. Failure can also be verified by checking the LEDS on each CP. If either a partial or total Common Control failure is detected, remove and then restore system power.
MAINTENANCE Once a faulty CP is identified, it can be replaced using the procedures in “Reseating and Replacing Circuit Packs” under “Routine Maintenance. ” Refer to the information in “Circuit Pack LEDs” under the “General Maintenance Information” to understand the meaning of the CP LEDs.
MAINTENANCE Table 4-B lists the test points (-5 V, +5 V, -48 V, and GND) for the power supply. The test points are located on the upper-right corner at the front of the cabinet. Table 4-C lists the voltages used by the CPs and symptoms voltages are missing.

MAINTENANCE CLEARING USER-DETECTED TROUBLES User-reported troubles are usually associated with voice or data terminal equipment or trunks. They can result from system-detected errors and are often solved by clearing system error conditions or alarms. This section presents trouble-clearing techniques and procedures for user- reported troubles.
MAINTENANCE Note : For problems with administration equipment that is not connected on a dedicated basis, refer to the Terminal Operations Manual, 555-540-710. Time-Keeping Troubles Symptoms: Clock Procedures: 1. Reset doesn’t reflect current time or date.
6. 7. 8. 9. Voice Check CP translations from the SAT to be sure that this CP has Check LEDs on CP. The red LED will be lighted if a fault on the CP affects all ports. Also, the red LED may be lighted if one or a few ports are faulty. Check Error Log for relevant messages.
MAINTENANCE 2. 3. 4. If you hear dial tone, continue with this test. Dial the digits 1234567890 *#. Y OU should hear a DTMF signal as each key is pressed. If the test passes, you will hear dial tone within 1 to 3 seconds after you enter #. Repeat the test for each touch-tone receiver.
MAINTENANCE Procedures : 1. Make sure that the appropriate ZTN79 CP is translated. 2. Check for the presence of -48 volts at test point on front of cabinet. Symptoms: Inoperative used. Procedures : 1. If LOCAL display-equipped voice terminal when LOCAL button is button/lamp activate LOCAL button.

MAINTENANCE Figure 4-12. Clearing Virtual Facilities Troubles (Sheet 3 of 3) 4-8 8.
MAINTENANCE Trunk Troubles Many trunk troubles originate in the central office (CO) facilities. The first step in identifying trunk troubles should be to check for presence of dial tone at the Trunk Access Equipment (TAE). If required, check the Error Log records, and make a trunk test call.
MAINTENANCE 5. Listen for dial tone from the accessed trunk. If dial tone is not present, isolate the fault to a trunk port CP or location in the trunk access equipment, etc., using a test set. 6. If dial tone is present, dial a working outside number.
MAINTENANCE 6. If “no loop current on outgoing call” is displayed, either of the above conditions could be true. It is more likely, however, that the facility is down . 7. Place an outside call on the line using the trunk test call procedures listed in outgoing Trunk Problems.
MAINTENANCE 8. 9. 10. 11. 12. If the problem does not move, replace the Ground Start CP. If the problem moves, the fault is with the CO. Notify CO personnel through the proper channels. If “Ringing no ground” is displayed, the T and R leads may be reversed in the trunk access wiring.
MAINTENANCE 3. 4. 5. 6. 7. 8. 9. ● CO failure to release after PBX disconnect ● CO belated release. These messages indicate CO problems. The first three errors are very common when DID trunks are installed. The CO should be notified through the proper channels about any of these problems.

6. 7. 8. 9. 10. 11. 12. 13. 14. If +7 volts are not present, the ADU is not receiving enough power from the data terminal and must be locally powered. If the ADU is powered from a local transformer, make sure that a 3- pair or 2-pair modular cord is connected between the transformer and the ADU.
MAINTENANCE Multiple Troubles or Trouble That Cannot Be Diagnosed Symptoms: Red LED is lighted on all port CPs. SAT displays this message: “FAIL : CPU : ARC H ANGEL INSANE: CHECK ZTN85: TERMINATOR?”. Procedures : 1. 2. 3. 4. 5. Check that the TDM bus terminator card(s) is installed in the rear pin field(s) .
MAINTENANCE Symptoms : Red LED is lighted cm several port CPs. Procedures: 1. 2. 3. 4. . Check the power supply to be sure that it is providing correct voltages (see “Power Supply Trouble’ ‘). Check the frontplane connector and the CPU/Memory CP, and replace any faulty unit(s).

GLOSSARY GLOSSARY The following is a list of definitions of terms used in System 25 documentation. Administe r To access and change the parameters associated with the services or features of the system. Analog Data Endpoint Data endpoints connected to the system by (built-in or stand-alone) modems.
Attendant The operator of the attendant console. Attendant Console ● Direct Trunk Console: An electronic call-handling position with pushbutton control.
GLOSSARY Buffe r A circuit or component that isolates one electrical circuit from another. Typically, a buffer holds data from one circuit or process until another circuit or process is ready to accept the data.
GLOSSARY Central Office Codes The first three digits of a 7-digit public network telephone number. These codes are numbered from 200 through 999 and are sometimes referred to as NNXS. Central Office Trunk A telecommunications channel that provides access from the system to the public network through the local central office (CO).
GLOSSARY Covering User The person at an alternate answering position who answers a redirected call. Data Channel A communications path between two points used to transmit digital signals. Data Communications Equipment (DCE) Refers to a specific RS-232C interface connector configuration.
GLOSSARY Delay-Dial Tie Trunk Digital Digital After a request for service (called a seizure) is detected on an incoming trunk, the system sends a momentary signal followed by a steady tone over the trunk. This informs the calling party that dialing can start.
GLOSSARY Dual-Tone Multifrequency (DTMF) Industry terminology for touch-tone calling. Emergency Transfer Unit (ETU) Provides direct connection of designated Power Failure Transfer (PFT) registered voice terminals to the CO during a power failure or other service interruption.
GLOSSARY Facility By technical type these include loop-start, ground-start, DID, data, and automatic ringdown trunks. These facilities may be accessed by their facility access codes (FACS). Restriction Level (FRL) A restriction parameter associated with the Automatic Route Selection (ARS) feature.
GLOSSARY Ground-Start Trunk On outgoing calls, System 25 transmits a request for service to the distant switching system by grounding the trunk ring lead. When the distant system is ready to receive the digits of the called number, that system grounds the trunk tip lead.
Loop-Start Trunk Modem Modem Simplest type of central office (CO) trunk. Calls are originated by providing a dc path between the tip and ring leads. The CO detects the loop current thus drawn and returns dial tone. Incoming calls are signaled by the CO placing an ac ringing voltage between the tip and ring leads.
GLOSSARY Number Plan Area (NPA) The area code. Off-Premises Station (OPS) An arrangement provided by the local telephone company permitting remote terminal equipment to operate as though it were directly connected to the system. This tariffed service can be provided only for FCC-registered single-line voice terminals.
GLOSSARY ● Floating— Assigned to visitors who will be moving about the premises. Floating PDCs may be associated with the attendant position or may be “logged in” by the user at any voice terminal. Calls to the floating PDC will ring at the terminal where “logged in.
Protocol A set of conventions or rules governing the format and timing of message exchanges to errors . Public Network The network that can be or long-distance calling. Queu e control data movement and correction of openly accessed by all customers for local An ordered sequence of tasks to be processed.
GLOSSARY Reorder Ton e Atone repeated 120 times a minute; indicates that at least one of the facilities, such as a trunk or a digit transmitter, required for the call is not available.
GLOSSARY Switch The software-controlled communications processor complex that interprets dialing pulses/tones/keyboard characters and makes the proper interconnections both within the system and outside the system.
GLOSSARY Terminal Equipment Equipment used to change information (sound, keystrokes) into an electrical signal compatible with System 25’s port circuits. (Voice and data terminals are the two primary types.) Tie Trunk A telecommunications channel that directly connects two private switching systems.
GLOSSARY Trunk Group Telecommunications channels assigned as a group for certain Trunk Port The hardware (circuit pack) providing an interface between the system and central office (CO)/network trunks. Unit Load A measurement used to evaluate a System 25 cabinet’s power load capacity.
