Locate the Tie Trunk port terminal connections at the cross-connect field. Consult the appropriate table below for either 110-type or 66-type hardware. 11. At the cross-connect field, disconnect outside trunk facilities from the Tie Trunk ports and mark the disconnected wires for reconnecting the Tie Trunk ports to their normal configuration later. The D Impact Tool (AT-8762) is required to perform this step. 12. Use jumper wires (DT 24M-Y/BL/R/G and DT 24P-W/BRN) and the D Impact Tool to connect wiring between the two ports assigned in Step 9 at the cross-connect field. For example, if the two ports on the Analog Tie Trunk circuit pack are port 1 and 2, connect the wirings as shown below: 13. Check all wirings to verify good connections between the two test ports. 14. Place a call from one voice terminal to another voice terminal using the Tie Trunk ports assigned. Dial TAC and extension. For example, if TAC of Tie Trunk group is 110 and station number is 5012, then dial 110 5012. If the call cannot be made, either one of these ports could be defective. There are four ports on the TN760. Try different combinations to determine defective ports. 15. If there is a defective port on the circuit pack, try to switch to an unused port. If all ports are normally used, then replace the circuit pack. 16. Disconnect the jumpers between two ports. Then use administration terminal and trunk printouts to restore all trunk group changes to normal values.Port Assign two of the ports from the tie trunk.

If this information is to be saved, enter the reset system 4 command. The command will take several minutes to complete, and will result in saving of the Error Log to the MSS. !CAUTION: Before powering down a cabinet or carrier that contains DEFINITY AUDIX circuit packs (TN566 and TN2169), you must first power down the AUDIX unit to avoid damage to the AUDIX software Instructions for powering down this unit appear on the circuit pack and in DEFINITY AUDIX documentation.
DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 Additional Maintenance Procedures Page 6-40 Automatic Transmission Measurement System (ATMS) 6 !CAUTION: If there is an alarm or problem suspected on the Tape or Disk Circuit packs do not save translations or announcements to the affected device. If there is an alarm or problem suspected with the Host Adapter circuit, do not save data to either MSS device. Saving data under these circumstances can destroy good copies of the file. If necessary, obtain a spare tape cartridge to save data. To remove power to the cabinet: 1. If the cabinet is the PPN, execute save translation and save announcement unless a tape drive problem is active. 2. Set the Emergency Transfer switch(es) in the affected cabinet to ON. In the PPN these are located on the SYSAM circuit pack(s). Set both in a system with duplicated SPE. In an EPN the switch is located on the EPN Maintenance circuit pack. This locks the system in the emergency transfer mode until the trouble is cleared. 3. Depending on which type of cabinet you are powering down, do one of the following: nIn an AC-Powered multi-carrier cabinet, set the circuit breaker to OFF at the Power Distribution Unit. nIn a DC-Powered multi-carrier cabinet, turn off the DC Power supply. nIn an AC-Powered single-carrier cabinet stack, turn off the power in each affected carrier individually. The ON/OFF switch is located at the back of the carrier behind the WP-91153 Power Unit. nIn a DC-Powered single-carrier cabinet stack, turn off the power in each affected carrier individually. The ON/OFF switch is located at the back of the carrier behind the 676B Power Unit. 4. Power is restored by reversing the action taken above. When restoring power to a PPN, the system will reboot. When restoring power to an EPN, the EPN will under go a restart. This process is described under EXP-PN in Chapter 9, ‘‘ ABRI-PORT (ASAI ISDN-BRI Port)’’. If a powered down carrier contains a 676B Power Unit, the 676B must have been powered down for at least 10 seconds for the unit to restart. Automatic Transmission Measurement System (ATMS) The ATMS performs transmission tests on analog trunks to determine whether they are performing satisfactorily. The switch automatically originates test calls from an Originating Test Line (OTL), over the trunks to be tested, to a Terminating
DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 Additional Maintenance Procedures Page 6-41 Automatic Transmission Measurement System (ATMS) 6 Trunk Line (TTL) on the switch at the far end of the trunk. Several different measurements of noise and attenuation are made and compared to administered thresholds. Test measurements can be viewed in the form of detailed or summary reports which are described below. ATMS test calls can be initiated on demand from the management terminal, or automatically by ATMS Trunk Test Schedules. For complete details on how to set up ATMS Trunk Test Schedules, see Chapter 4 of Generic 3 V2 Implementation, 555-230-653 . Demand tests are run with the test analog-testcall command which is described below. Trunk groups can be administered to respond in different ways when a trunk fails to perform within the administered thresholds. Alarms and errors may be logged, and the trunk can be automatically busied out. When a trunk fails an unacceptable threshold twice, the system will busy it out if the trunk group is so administered and doing so will not exceed an administered limit (25, 50, 75, or 100% of the members in the group). This limit is not applied to later busyouts caused by other factors. Trunks can be manually returned to service by changing the thresholds and running a demand test or by using the release command. ATMS Requirements ATMS tests utilize the analog port (port number 01) on a TN771 Maintenance/Test circuit pack. Each PPN contains one TN771. Depending on system configuration, each EPN may also contain one TN771. Multiple TN771s allow up to 3 concurrent test calls. AMTS tests are designed to operate on the types of trunks found in the US, and the TN771 analog port is Mu-law companding only. The tests will not be useful in all environments. For ATMS tests to run, several administrative prerequisites must be met. The following list shows the field entries necessary to enable testing.
DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 Additional Maintenance Procedures Page 6-42 Automatic Transmission Measurement System (ATMS) 6 Running ATMS Tests (Test Analog-Testcall Command) ATMS test calls can be originated either on demand or according to the ATMS Test Schedule. Test schedules are set up with test-schedule commands which are described in DEFINITY Enterprise Communications Server Release 5.4 Administration and Feature Description . Demand test calls are originated by the test analog-testcall command. You can specify testing of an entire trunk group, an individual trunk, or all trunks on a single circuit pack. Trunks can be addressed by either group/member numbers or circuit pack/port locations. The type of test call, the number of the testing line on the far-end switch and various other parameters must be administered on the trunk group form before the command can execute. Table 6-7. ATMS Administration Form Field Entry/Remarks System-parameters customer optionsATMS?y (You must logoff/login in order for changes on this form to take effect.) Station Extension At least one TN711 analog port must be assigned.

ATMS Thresholds (page 4 of form)y This page is used to specify performance thresholds, the type and access number of the far-end TTL, and system response to test failures. Hunt Group (Optional, for incoming test calls) If the system has several TN771s, you can use this form to make up a hunt group of TTLs so that one extension can be used for the whole pool. ATMS Trunk Test Schedule(Optional) To set up a test schedule, see Chapter 4 of Generic 3 V2 Implementation, 555-230-653.
DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 Additional Maintenance Procedures Page 6-43 Automatic Transmission Measurement System (ATMS) 6 Normally you should invoke only the full or supervision tests. The other options are provided mainly for use in setting up an ATMS schedule. Which tests are run depend on the type of TTL at the far end to which the test call is made. The following table shows which tests are run for each type of TTL. Command syntax is as follows: test analog-testcal trunkgroup#/| member#| port UUCSSpp | boardUUCSS [full | supervision | no-selftest | no-return-loss | no-st-or-rl] [repeat#][schedule] Input Parameters Different TTLs have different measurement capabilities and you will need the following information about specific TTL types. This table does not include the self-test nor does it distinguish between measurements for different test tone levels. trunk addressesYou can specify a single trunk or several trunks by using trunk, port, or board addresses. These parameters are described in the introduction to Chapter 8, ‘‘ Maintenance Commands’’. If you enter a trunk group number without a member number, all members of the group are tested. full This executes the most comprehensive test call available using the administered test set type. “Full“is the default. supervision This test takes about 10 seconds and simply confirms the presence of testing capability at the far end. no-selftest This executes the full test, but skips self test sequences. This saves about 20 seconds on the type 105 transmission test and has no effect on type 100 and 102 transmission tests. no-return-loss This executes the full test, but skips return loss sequences. This saves about 20 seconds on the type 105 transmission test and has no effect on type 100 or 102 transmission tests. no-st-or-rl This executes the full test, but skips the self test and the return loss sequences. This saves about 40 seconds on the type 105 transmission test and has no effect on type 100 or 102 transmission tests. repeat # This specifies repeating the tests up to 99 times. The default is a single run of the tests. schedule This qualifier brings up a form for scheduling execution of the test at a later time. This is not the same as setting up an ATMS Test Schedule, which is described above.

If the test aborts or fails, an error code indicating the cause is returned. The error codes are explained in the CO-TRK and TIE-TRK sections of Chapter 9, ‘‘ABRI-PORT (ASAI ISDN-BRI Port)’’. When the trunk is being used for call 1. Return Loss includes Singing Return Loss High Frequency, Singing Return Loss Low Frequency, and Echo Return Loss. Table 6-8.
