    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. Clearing the most serious logged fault may clear some or all of the other faults.

  • Page 188: Common Control Problems

    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”). Other repair procedures may also require the system to be powered down. After removing a suspected faulty CP, do the following: Visually inspect the CP.

  • Page 189: Maintenance Failure

    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.

    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.

    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. If the Error Log notes an error related to the touch-tone receivers, the receivers are performing below system requirements.

    MAINTENANCE Power Supply Replacement To replace the power supply, follow these steps: Danger: Hazardous voltages are present on some backplane pins. Unplug power cord from the outlet, and wait at least 5 minutes before removing rear cover or power supply. Remove the front cover of the cabinet.

  • Page 247: Fan Assembly Trouble

    Fan Assembly Trouble The fans should always be operating when the system is receiving ac power and the cabinet switch is turned on. If the fans are not operating, be sure that the system is receiving ac power. if the system is receiving power and the fans are still not operating, the ac power connection to the fan assembly is faulty or the fans themselves are faulty (for example, burned out motors).

    Trunk Troubles Many trunk troubles originate in the central office 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. Note that it is sometimes difficult for the user to detect or identify trunk troubles.

  • Page 267: Incoming Trunk Problems

    MAINTENANCE 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. If dial tone is present, dial a working outside number. Verify that the call is complete.

    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 d o w n . Place an outside call on the line using the trunk test call procedures listed in outgoing Trunk Problems.

  • Page 269: Did Trunks Troubles

    MAINTENANCE 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.

Data Communications Equipment (DCE) Refers to a specific RS-232C interface connector configuration. The DCE devices are designed to interface directly (pin-for-pin) to Data Terminal Equipment (DTE).
  • Page 419 GLOSSARY Delay-Dial Tie Trunk 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. This type of trunk allows dialing directly into the system; that is, the digits are received as they are dialed.
  • Page 420 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. E r l a n g A traffic measuring unit that expresses the load of one or more traffic-generating devices (36 CCS equals 1 erlang—see CCS [Hundred Call Seconds]).
  • Page 421 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). Facility Restriction Level (FRL) A restriction parameter associated with the Automatic Route Selection (ARS) feature. Determines whether a particular station can access a particular trunk.
  • Page 422 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. When System 25 detects this ground, it removes the ground from the ring lead and the trunk is ready for service.
  • Page 423 Loop-Start Trunk Simplest type of central office (CO) trunk. Calls are originated by providing a dc path between the tip and ring leads. The CO detects current the loop signaled by the CO placing an ac ringing voltage between the tip and ring leads.
  • Page 424 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.
  • Page 425 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.
  • Page 426 Protocol A set of conventions or rules governing the format and timing of message exchanges to e r r o r s . Public Network The network that can be or long-distance calling. Q u e u e An ordered sequence of tasks to be processed. Q u e u i n g The process of holding calls in order of their arrival to await connection to an attendant, to a DGC group, or to an outgoing trunk.
  • Page 427 GLOSSARY Reorder Tone 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. Also called Fast Busy Tone. Single-Line Voice Terminals Single-line voice terminals served by a Tip Ring Line or Analog Line circuit pack (2500 series and 7101 A voice terminals or industry standard Dual-Tone Multifrequency equivalent).
  • Page 428 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. The switch itself consists of a digital computer, software, storage device (memory), and associated circuit packs hardware necessary to perform the actual connections.
  • Page 429 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. Time-Division Multiplex Bus A special bus that is time-shared by preallocating short time slots to each transmitter on a regular basis.
  • Page 430 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.
