Random issues such as:
1. Most commonly - user complains that his SS4150 does not work in handsfree mode, spkr audio is muted until mic button is turned off. A set reboot solves it. I'll have 8~10 reports of this anomaly per week, scattered all around the machine, no rhyme or reason as to active controller or peripheral location. It will sometimes plague us for 2~3 days in a row then we'll go maybe a week without another recurrence.
2. User reports that the first incoming call in the morning to his multiline set is sometimes presented in handsfree mode even though the handset was lifted to answer. Subsequent calls are ok. We'll get 1 these complaints perhaps every 3~4 months, not often, but perplexing. I think the msg switch has maybe missed the event or doesn't know the status of the hookswitch as it only occurs on 1st call of the day (flwg activity xfr)
3. User complains that handsfree speaker audio sounds like single-sideband (unintelligile Donald Duck gibberish). A set reboot solves it. We get at least one report of this per month.
4. Attendant console (SS700) reports communications failure onscreen but appears to instantly recover and continue working. Happens every day. Have tried recabling, different PLID, different console, different handset cord, etc. SS700 is on a dedicated PLID with no other sets on the card. Have seen this on the Attendant's console as well as on the maint console in my office. (both are SS700)
5. Machine raises a Major, reporting loss of several DTMF receivers all common to one PSC. A directed test will clear these, but then a few minutes later the PSC reloads. If you leave it alone (without doing a directed test) it will eventually clear the failed DTMF Rcvrs on its own and without causing the PER to reload. We'll see this a couple times a month, never on the same PSC - again purely random around the switch during peak traffic in the AM.
6. Machine raises a Minor, reporting loss of only one DNIC plid. Again, purely at random around the switch. Only happens in the early AM, a couple hours or so after the DBMS check completes. We'll see this anywhere from 2~3 times a month to 2~3 times a week, never on the same PLID, never in the same PER node, doesn't follow with any specific plane being active.
7. Machine raises a Major & switches planes spontaneously, reporting loss of tone generator. Happens infrequently, every 2~3 months. Leave it along and it will come back on its own and be fine for amother 2~3 months. Sliding the MCIII out and in doesn't seem to have an impact on frequency of occurrence. Randomly, seldom the same plane.
Machine is on LW34.2.7.4 MFRD 21, Traffic level 20. These issues, one and all, have been present in the machine for years, and seem to show up every time we get above 1300 multiline sets in service. I really don't think there's anything wrong with the machine other than msg switch overloading.
Nightly activity switch goes OK, daily DBMS check always clean. Drives and MCIII are all original, installed with system in 1999
