[cisco-voip] VWIC2-2MFT-T1 voice and data coexist on same WIC

[Steve G]

Thanks Andrew,
     This is the response I was looking for.  I will try your configuration
and see if we do nto experience th ehigh amount of clock slips that we were
getting.

The link below has me perplexed a little bit.  It states that you can
independently source the clock for data applications ONLY, and not voice.

"The Cisco 2-port MFT VWIC2s also can enable each port to be clocked from
independent clock sources for data applications. This independent clocking
capability is not supported for voice applications or with the Cisco
ATM/Voice Advanced Integration Modules (part number AIM-ATM, AIM-VOICE-30,
AIM-ATM-VOICE-30"

The best way I have found to get data and voice to work properly on the
same vwic-2mft card without any slips is to configure the data t1 as
"clock source internal" and the pri port as "clock source line".

for example data t1 in 2/0 and voice pri in 2/1:

network-clock-participate slot 2
network-clock-select 1 T1 2/1

!
controller T1 2/0
framing esf
clock source internal
linecode b8zs
channel-group 0 timeslots 1-24 speed 64
!
controller T1 2/1
framing esf
linecode b8zs
cablelength short 133
pri-group timeslots 1-24 service mgcp
