We have a Cisco 3845 connected to a ACD (Aspect) with several E1s.
My question is around slips, i`ve noticed the following :
E1 1/0 is up.
Applique type is Channelized E1 - balanced
No alarms detected.
alarm-trigger is not set
Version info Firmware: 20071011, FPGA: 255, spm_count = 0
Framing is CRC4, Line Code is HDB3, Clock Source is Line.
Current port master clock:recovered from backplane
Data in current interval (256 seconds elapsed):
0 Line Code Violations, 0 Path Code Violations
23 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins
23 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs
Total Data (last 24 hours)
0 Line Code Violations, 0 Path Code Violations,
7807 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins,
7807 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs
So there are several slips in a short time period but I don`t know what impact that is having if at all from a end user perspective ( dropped calls ? poor quality )
Also in regards external clocking the Cisco router is configured for line ( External ) and doesn`t have any carrier E1`s connected.
Should I be arranging such a connection to clock with in the ACD & Gateway or are these number`s minimal ?
Or should I experiment and change clock on the gateway to internal to see if its any worse or better ? I assume doing this would be dependent on the ACD being configured in such a way also.
I`m new to the voice world so thanks for any advice forthcoming !
I don't know much about MGCP but my understanding is that clocking is configured exclusively at router level, either under controller T1/E1, or with the network-clock commands mentioned above.
