maintenance software, the test is queued and run when the maintenance activity
finishes.
Measurement data gathered by analog testcalls can be retrieved with the list
testcalls command which is described below. Which measurements are made
and recorded depends on which type of test is specified and the capabilities of
the far-end TTL.

Measurement reports contain data on trunk signal loss, noise, singing return loss, and echo return loss, and are used to determine the quality of trunk lines. The system maintains a database with the results of the last test for each trunk. System resets clear all transmission test data, and ATMS measurements are not backed up by the Mass Storage System. ATMS parameters are administered on page 4 of the trunk group form. These include thresholds for marginal and unacceptable performance. On the screen display, measurements that exceed the marginal threshold are highlighted. Measurements that are exceed the unacceptable level appear flashing, indicating unusable trunks. Trunk groups can be administered to log errors and alarms, and busyout the failed trunk in response to such results. The detailed report lists measurements for each trunk group member. The summary reports lists trunk groups as a whole. Which measurements are displayed depends on what type of test, if any, was last run on the trunk, and the capabilities of the TTL on the switch at the far end of the trunk. See the preceding description of the test analog-testcall command. A blank line indicates that no test data is available for that trunk or group. The number of pages of each report is dependent upon the selection criteria and the number of outgoing trunks in the system. About 10 measurements can be listed on a page on the administration terminal, or about 50 measurements can be listed on a printer. By default, reports list all measurements. Filtering can be used to limit the output. For example, the report can be set up to print only failed measurements. The syntax of the command is as follows: list testcalls detail | summary [port UUCSSpp] [grp group#] [to-grpgroup#] [mem member#] [to-memmember#] [resultresultID> | not-resultresultID] [count#] [print | schedule] Error CodeThis numerical code indicates the reason for a failure or abort. The codes are explained in the CO-TRK and TIE-TRK sections of Chapter 9, ‘‘ ABRI-PORT (ASAI ISDN-BRI Port)’’.

ATMS Detail Report
This report is divided into two sections. The upper section lists the trunk group,
trunk type, trunk vendor, TTL type, and the user-defined threshold values
administered on page 4 of the trunk group form. The lower section lists the most
recent set of measurements for each member of the trunk group selected for the
report. Measurements that exceed the marginal threshold, but not the
unacceptable threshold, are highlighted. Measurements that exceed the
unacceptable threshold blink, identifying unusable trunks. When a marginal or
unacceptable measurement is located, scan the top section to find out how far
the measurement deviates from its defined threshold.
Output Fields - ATMS Detail Report
Measurements are made in both directions, near to far end, and far to near end.
For each measurement, there are 2 columns on the lower part of the report, “NE”
for near end, and “FE” for far end. These refer to the destination end for that
measurement. Busied Out Trunks The number of trunks that were busied out in response to test
failures. These may be caused by hardware problems, incorrect
threshold values, and so on.
Group The trunk group number selected.
Type The trunk group type.
Vendor The vendor of this trunk group.

DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 Additional Maintenance Procedures Page 6-51 Automatic Transmission Measurement System (ATMS) 6 ATMS Measurement Analysis ATMS compares the results of the test measurements with threshold values to identify trunks that are out of tolerance or unusable. Once a defective circuit has been pinpointed, a proper analysis must be made to determine the appropriate action to take on the facility failures. Although there is no “right” procedure for every situation, the following items will help in troubleshooting problems: nIf a circuit fails an ATMS transmission test, it does not necessarily mean the trouble is in the facility itself. The problem could be caused by a faulty test line, bad switch path, or a variety of other reasons. nIf a circuit fails a transmission test but successfully passes a supervision test, some of the items mentioned above are probably not at fault, since proper call routing and circuit continuity are required for successful of a supervision test. nIf several circuits in the same group are failing, this could indicate the failure of some common equipment (such as a carrier system, test line, or cable) or erroneous information in the threshold tables. nWhen a test call can be successfully made, but not completed, either the OTL or TTL is probably defective. For this failure type, further ATMS testing might be seriously impaired, but the system is not otherwise affected. nIf a test call cannot be successfully made, the wrong number might have been dialed, the far-end device might be busy, the far-end device is defective, or there is a serious trunk failure obstructing the call. SRL-LO Singing return loss from 0 to 40 dB between the sum of the circuit (repeater) gains and the sum of the circuit losses. SRL-LO occurs most often in the frequency range of 200 to 500 Hz. SRL-HI Singing return loss from 0 to 40 dB between the sum of the circuit (repeater) gains on a circuit and the sum of the circuit losses. SRL-HI occurs most often in the frequency range of 2500 to 3200 Hz. ERL Echo return loss from 0 to 40 dB between the level of signal strength transmitted and the level of signal strength reflected. ERL occurs most often in the frequency range of 500 to 2500 Hz

LED Indicators Page 7-1 Terminal Alarm Notification 7 DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 7 7LED Indicators If a maintenance object in the system begins to fail some of the periodic tests, the system automatically generates an alarm. This alarm indicates to maintenance personnel that action is required to restore the system to a normal condition. The system identifies three levels of alarms: nMajor Alarms — Failures that cause critical degradation of service and require immediate attention. nMinor Alarms — Failures that cause some degradation of service, but do not render a crucial portion of the system inoperable. This condition requires action, but its consequences are not immediate. Problems might be impairing service to a few trunks or stations or interfering with one feature across the entire system. nWarning Alarms — Failures that cause no significant degradation of service or failures in equipment external to the system. Warning alarms are not reported to the attendant console or INADS. Alarms are communicated to the system users and technicians by entries in the Alarm Log and the lighting of LEDs located on the attendant console, on all circuit packs in the switch cabinets, and, optionally, on customer-designated voice terminals. Terminal Alarm Notification Terminal Alarm Notification is an optional feature which displays several types of alarms on voice terminals with administered feature buttons or the attendant console. A maximum of ten digital and/or hybrid voice terminals may be used. When an alarm occurs, the green status LED associated with the assigned button will be in a steady state. The lamp may be turned off by pressing the
DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 LED Indicators Page 7-2 Attendant Console LEDs 7 button associated with the lighted alarm lamp. If the lamp is turned off, and the alarm has not been resolved by the time maintenance reschedules testing, the green status LED will resume its steady state. The following alarms are displayed: Attendant Console LEDs The console has two red LEDs, labeled “ALM” and “ACK.” The ALM LED lights steadily when there is a Major or Minor alarm at the switch cabinet. The ACK LED lights steadily if the alarm has been successfully reported to INADS. If the system is unable to report the alarm to INADS, the LED flashes; this signals the attendant to call INADS and report the alarm. ac-alarm Administered Connection Alarm: a locally administered connection (ADM-CONN) has a Major, Minor, or Warning alarm active. pr-awu-alm Auto Wakeup Journal Printer Alarm: the automatic wakeup journal printer has a Major, Minor, or Warning alarm active. ds1-alarm DS1 Facility Alarm: a DS1-BD has an off-board Major, Minor, or Warning alarm active. trk-ac-alm Facility Access Alarm: The facility access trunk test feature is activated. major-alrm Major Alarm: The system has logged a Major Alarm. mj/mn-alrm Major/Minor Alarm: The system has logged a Major or Minor Alarm. pr-pms-alm PMS Printer: The Property Management System printer has a Major, Minor, or Warning alarm active. rs-alert Reset-Alert: reset system 2 or 3 has been performed. cdr1-alrm Call Detail Recording Alarm: The Primary CDR Link has a Major, Minor, or Warning alarm active. cdr2-alrm Call Detail Recording Alarm: The Secondary Link has a Major, Minor, or Warning alarm active. pr-sys-alm System Printer Alarm: The System Printer (SYS-PRNT) has a Major, Minor, or Warning alarm active. pms-alarm The Property Management System has a Major, Minor or Warning alarm active.
