sundance-communications.com/forum Forums TDM Business Telephone Systems Nortel Telephones & Systems Calls dropping

I installed a BCM 400 with DTI card the customer complains of calls dropping the telco has cleared the PRI saying there are no errors or troubles with the pri. I have swapped the DTI and awaiting to see if the trouble presists the BCM also did not log any errors in the PRI settings. Anyone seen this before?

Are you able to duplicate the problem? How often does it happen? Are there multiple users complaining?

I have not been able to duplicate it, also I have not been forunate enough to have it happen while I was there. It seems to happen often in as a couple times a day. Also it is not one person seem to affect the whole office.

Is it possible that the clock source on the T-1 is set to "Master" rather than "Primary"? This can cause the condition you describe (but usually more lost calls than what you have).

If clock source is set to Primary already, I would have the users keep track of the calls that get dropped (incoming or outgoing, cell phone or land line, etc.) to try and find the source of the problem. Maybe they are cell phone callers losing signal!?!? (it could happen)

Thanks, it is set to primary. It kind of looks like Im going to have start busying out B channels to see if i can prove one particular channel. But the customer does not seem to want to be bothered with keeping track of dropped calls. Anyways thanks for your help.
