3. Coin Control Failures (COIN CONTR FAILURES): Counts the number of stuck |
coin conditions and coin telephones served by the office which had coin |
relays that were out of limits. |
4. Automatic Identification Outward Dialing Special Billing Number Billing |
(AIOD SBN BILLING): Counts the number of times the AIOD equipment fails to |
bill a local PBX number correctly. |
5. Dial Tone Speed Test (DTST): Counts the number of times the customer has to |
wait an excessive amount of time for the system to process the call because |
trunks in the desired trunk group are busy or the system is overloaded, |
causing queuing for equipment. The count includes 3-second and 11-second |
delays. |
NOTE: |
Maintenance personnel may find it necessary |
to suspend the running of the DTST because in |
certain trouble conditions DTST may generate |
traffic that would interfere with maintenance |
activities. Extended or frequent use of this |
feature is not recommended. To discourage the |
unnecessary use of this function, the PM01 output |
message will include a one-line message alerting |
maintenance personnel to it's use. |
6. CAMA Lost Billing (CAMA LOST BILLING): Counts the number of times a CAMA |
call is handled but due to hardware failure, no AMA register is available |
which is necessary for billing. |
7. CAMA ANI Failures (CAMA ANI FAILURES): Counts the number of calls for which |
ANI failure digit is received. |
8. Receiver Attachment Delay (RCVR ATT DELAY): Counts the number of times a |
receiver connection was not made in 4 seconds. |
9. Receiver Attachment Delay Recorder (RADR Inhibit Usage): Counts tR described. |
This is rather simple when you think about it and is one example of how a once |
shattered network is working together. |
Some Sample CP ID Uses |
---------------------- |
This can be used by large telephone ordering companies to instantly display a |
record of that persons credit, previous orders, etc... before the call is even |
answered on the attendant's terminal. |
When someone logs onto a computer, the originating # is listed on the user log |
along with the account name, etc... so that if--------- |
The software EA phases may be initiated by the following sources: |
1. A failure by the system to answer an interrupt request |
2. An E-to-E cycle becoming excessive |
3. An E-to-E priority class frequency failure |
4. An excessive rate of interrupts |
5. Two successive data validation failures |
6. The time spent in a phase becoming excessive |
7. Aborting of a phase |
The number of EA phases is printed on the PM01 output message. |
Interrupts |
---------- |
The number of various maintenance interrupts provides a picture of nonroutine |
maintenance action taken by the system. These interrupts are generally not as |
serious as a higher order EA phase, but they do interrupt normal call |
processing to correct possible hardware problems. A counts of these interrupts |
will give a good indication of the state of the systems' equipment. This is |
printed on the PM01 output message. |
Network Failures |
---------------- |
The network failure counts are provided to give an indication of how well the |
network is completing and terminating calls. Each time a network failure |
occurs in the system an 'NT' output message is printed. The following are |
printed as part of the PM01 message: |
1. Supervisory Scan failure (SUPF) |
2. False cross and ground test failure (FCGF) |
3. Ringing Current Failure (RC) |
4. Low-line resistance failure (LLR) |
5. Power Cross test (PX) |
6. Restore verify failure count (RVFY) |
7. Showering line test failure (SHWL) |
8. Call Cutoff Failure (CO) |
