P0603534 02Modular ICS 6.1 Installer Guide Troubleshooting These troubleshooting procedures allow you to solve many problems in the Norstar system. Follow these procedures before replacing any components. Where more than one procedure is given, the procedures represent different options from which you can select one. Only qualified persons should service the system. The installation and service of this unit is to be performed only by service personnel having appropriate training and experience necessary to be aware of hazards to which they are exposed in performing a task and of measures to minimize the danger to themselves or other persons. Electrical shock hazards from the telecommunication network and AC mains are possible with this equipment. To minimize risk to service personnel and users, the ICS must be connected to an outlet with a third-wire ground. In addition, all unused slots should have filler faceplates installed and the doors should be in place at the completion of any servicing. Service personnel must be alert to the possibility of high leakage currents becoming available on metal system surfaces during power line fault events near network lines. A risk point on the ICS is the power cord earth ground pin. These leakage currents normally safely flow to Protective Earth ground via the power cord. Therefore, it is mandatory that connection to an grounded outlet is performed first and removed last when cabling to the unit. Specifically, operations requiring the unit to be powered down must have the network connections (central office lines) removed first.
574 / Troubleshooting Modular ICS 6.1 Installer GuideP0603534 02 Troubleshooting procedures for Companion components are included in the Modular ICS Companion Installer Guide. Getting ready Before you begin troubleshooting, gather all the information that is relevant to your network configuration: • the Modular ICS Programming Record • records from people who use the network • information about other hardware and non-Norstar features within the public or private network Notify service provider of T1 or PRI signaling disruption. Notify your T1 or PRI service provider before disconnecting your T1 or PRI lines, removing power to your system, or performing any other action that disrupts your T1 or PRI signaling. Failure to notify your T1 or PRI service provider may result in a loss of T1or PRI service. Tips - Remember that you can check many of the system parameters without having to go into a programming session. Use Line Profile (≤••ÒȈ‰) from a T7316/ T7316E, an M7310 or an M7324 set, to check programming for any line. Use Set Profile (≤••Í‰Ê) from a T7316/T7316E, an M7310, or an M7324 telephone, to check programming for any telephone. Use Button Inquiry (≤•‚) to check the buttons on a particular telephone.
Troubleshooting / 575 P0603534 02Modular ICS 6.1 Installer Guide Types of problems The problems you encounter will likely occur into one of the following categories: Misunderstanding a feature A problem may be reported because a Norstar user is unfamiliar with the operation of a given feature. You may be able to solve the problem simply by demonstrating how to use the feature correctly. Programming errors You may encounter problems caused by errors in programming. A feature may have been programmed incorrectly or may not have been programmed at all. Refer to the section on programming the feature to ensure all the parameters have been correctly programmed. Wiring connections Wiring problems are caused by loose, unconnected, or incorrect wiring. Use the procedures in the section on Checking the hardware as a guide. Equipment defects You may encounter problems caused by Norstar equipment defects. See the appropriate section for problems related to the system hardware.
576 / Troubleshooting Modular ICS 6.1 Installer GuideP0603534 02 General troubleshooting procedure 1. Diagnose the trouble by determining: • the types of problems users have experienced • the frequency of the problems • how many telephones are affected 2. Check how a feature is being used. A problem may have been reported because of a misunderstanding about how a feature works. Confirm that the person who reported a problem understands the intended use and operation of any feature in question. 3. Check for programming errors. Check that the programming recorded in the Programming Record is correct for the intended operation of the system, and verify that the programming has been correctly entered. 4. Run a Station set test ( ≤°‚fi). Instructions are included in the Modular ICS 6.1 System Coordinator Guide. 5. Check the wiring and hardware connections. 6. If the problem persists, run a Maintenance session as described in Beginning a Maintenance session on page 512. 7. If hardware is defective, replace it. 8. If the trouble requires expert advice, follow your company procedure for obtaining assistance.

Replace the problem telephone with a working one. 3. Enable the working telephone. Telephone dead 1. Run a Station Set Test (≤°‚fi). Detailed instructions are contained in the Modular ICS 6.1 System Coordinator Guide. 2. If more than one telephone is affected, refer to Data Module down on page 605. 3. Check for dial tone. 4. Check the display. 5. If the problem persists, replace the telephone with a working set of the same type. This ensures the programming is downloaded to the new set. 6. Check the internal wiring at both the modular jack and the distribution cross-connect. A TCM port should have between 15 and 26 V DC across the Tip and Ring when the telephone is disconnected. 7. Check the line cord.
Problems with telephones / 579 P0603534 02Modular ICS 6.1 Installer Guide Running a Maintenance session to test a dead telephone 1. Run a Maintenance session to ensure that the telephone is not disabled. See Port/DN status on page 514. 2. Disable the port to which the telephone is connected, using Port/DN status. 3. Enable the port to which the telephone is connected, using Port/DN status. Replacing a telephone In a powered-up system, an existing telephone can be replaced by a new telephone. A new telephone is one that was not previously in service within the system. Replacing telephones of the same type If an existing telephone is unplugged, and a new telephone of the same type is then plugged into the same jack, for example, replacing a T7208 set with another T7208 set, the new telephone acquires the programming and the internal number of the old telephone. This is normally done to replace a defective telephone. Replacing telephones of different types If an existing telephone is unplugged, and a new telephone of a different type is plugged into the same jack, the new telephone keeps the old internal number. The new telephone receives a default profile for a telephone of its type. You then need to program the terminal as described in the Modular ICS 6.1 System Coordinator Guide. If the telephone being replaced has more lines than the new telephone, automatic outgoing line selection may not work with the handsfree feature. A line must be selected manually.
580 / Problems with telephones Modular ICS 6.1 Installer GuideP0603534 02 Status of a telephone that was replaced The old telephone that was unplugged and replaced by a new telephone loses its programming and internal number. The internal number of the old telephone has been given to the new telephone. The programming has either been removed or given to the new telephone when it was plugged into the old jack. The replaced telephone, if it is plugged back into the system, is now treated by the system as a telephone not previously in service. Emergency telephone dead 1. Verify that the power at the ICS or Trunk Module is not on. 2. Verify that there is no dial tone at the emergency telephone. 3. Check that the external line and emergency telephone connections have been made correctly. 4. Ensure that the emergency telephone is not faulty by connecting it directly to the external line and listening for dial tone. 5. Verify that the ICS has a Loop Start Trunk Cartridge installed in slot 4. Verify that the Trunk Module has a Loop Start Trunk Cartridge installed in the left-most slot. 6. Verify that there is dial tone on lines 002 (ET1 on CD1) and 026 (ET2 on CD2) of the ICS and on the first line of each Trunk Module. 7. Replace the ICS if the emergency telephone is connected to the ICS or replace the Trunk Module if the emergency telephone is connected to the Trunk Module.
