BCM400 Dropping Calls

[thegenerallee]

As of early this week or very late last week a BCM 400 I've got has been dropping calls. The alarms showing up are as follows.

1.) Core Telephony - Digital trunking clock in free run.

2.) Core Telephony - "Degraded Minute"short term alarm threshold has been exceeded on the DTM. The module is in a no-new-calls state.

3.) Core Telephony - "Errored Second"short term alarm threshold has been exceeded on the DTM. The module is in a no-new-calls state.

#2 and #3 show up repeatedly but every minute or so. But #1 only makes an appearance about every five minutes.

I know that the solutions all say check cabling to DTM modules but would someone had to have physically unplugged something to cause these or could it have been a configuration change somewhere along the lines that could have triggered it?

Check your clock and make sure it is set as primary.

@hawks: Will do. But where within the BCM Manager can this setting be found. I haven't found it yet but I'll keep looking unless I hear further from you. Thanks!

@hawks: I believe I found it under "Resources -> Telephony Resources -> Selecting Modules Bus 6.0" for the PRI. If this is the correct location, then the "Clock source" setting is already set as "Primary external".

It sound like the provider. Check the wiring to smart jack. Re punch.

@cook1082: Thanks. I'm unfortunately about a 1000 miles away so I won't be able to check it in person. But I have contacted the provider to review the lines.
