100CSU-DSU Errors

[fatman01]

I'm getting 77 COMMAND BUFFER FULL and INVALID SANITY RESPONSE errors a day even after replacing the T1 card.
Also getting static on all incoming calls. The phone company came out and tested the line and is blaming my equipment. Changing the 100CSU-DSU showed no improvements.


Any help would be deeply appreciated.


Avaya Magix System

Is this T1 PRI service? Sounds like their switch type and protocol may not be compatible with the Magix. What is it? 5ESS? DMS100? What protocol are they using? AT&T Custom? NI1? NI2?

If your getting static on your calls suggest you check your timing, only thing on a T1 that will cause static is timing slips

tdaugirdas,


Yes it is a T1 PRI, 5ESS, using Custom protocol

Thanks for your reply

Has this been happening since installation? or is this condition a recent change? Is the routing working inbound? Are all types of calls working outbound? Do you know what the Telco claims their Switch Type and Switch Protocol settings are?

Also check the cabling from the NIU (smart-jack) to the switch, a bad or poorly made cable can cause the same symptoms by creating a flakey connection. I have seen people use stranded wire RJ-45 plugs on solid wire cable, which is just asking for trouble.
Also, I assume you have your primary clock source set to the board in programming.
If you have replaced the board and the issue remains, unless perchance you have another undiscovered hardware issue, the cause is most likely back towards the CO.

How many cabinets does your system have, and if you have more than one, did you power them up in proper sequence??

If not, this can cause the 100D module(s) to generate erroneous alarms. I have had this happen on a system with three cabinets and two 100D modules. To fix it, I disable the modules: test, reset, then restore. Clear the temporary alarms, then recheck to see if all is clear.

First I would like to thank everyone for all your help.

allisand,
I’m still looking into the timing thing. I’m kind of new at this stuff.

tdaugirdas,
This is a new condition, the static on incoming and outgoing just started and any device that connects through a modem looses connection within 2 minutes. The Telco claims the Switch Type is 5E and the Protocol is Custom.

phonesrus,
I have tested the cable but I will replace this evening. The clock settings are Active: yes, Synch source: Loop, PPM: 000.

syquest,
I have 2 cabinets with 1 100D in the first cabinet and fired them from right to left waiting 1 minute before powering the next. When I replace the cable this evening I will try test, reset and restore if the errors continue.

I have posted the PRI Info at:

if needed.


Thanks again for everyone’s help!!

And this is the error log:

Delete all of the existing processor errors in the permanent and transient logs - sometimes that causes problems. If the issue just started recently - it makes me think that maybe the switch at Telco end needs to be rebooted - followed by a reboot on your system. Are you using the CSU/DSU? Do you even need it? You could disable it - assuming all channels are voice. However, you would probably have to switch the cable connection to a T1 crossover configuration vs. straight-thru - and - see if that makes any difference. I would probably just go through a reboot on both ends first. First the Telco - and then you.
