i have a new t-1 i want to turn up using a VWIC-2MFT-T1 on both ends of the circuit. normally i would use a wic 1dsu t1 v2 on one end and a VWIC-2MFT-T1 on the other. i installed the VWIC-2MFT-T1 with the standard controller configuration (linecode b8zs, clocksource line, framing esf) and when i placed the t-1 in the controller i get interface serial 0/0:0 up line protocol down. i also configured the serial interface after i configured the controller.
my question is - is there any other configuration i may be missing since i am using a different hardware setup?
below is a capture of the interface while trying to turn up the circuit.
Serial0/1/0:0 is up, line protocol is down

Jerry,
Who is providing the clocking ? The telco ?
What's the Serial status on the router at the other end ? It could be a provisioning problem here, have you contacted the telco carrier ?

Can you provide to us the results of a SHOW CONTROLLER T-1 to see the status of layer 1 of the T-1. Is this T-1 actually provisioned for B8ZS/ESF or possibly D4 framing??

Possible that you need to set encapsulation ppp? If this T1 is not encapsulated with HDLC, it could cause issues (ie, like a MPLS circuit).

Make sure under your 'controller t1 0/1/0' you have 'channel-group 0 timeslots 1-24 speed 64'
From the look of your output, you're only using timeslot 24 now.

good point - i'll give it a shot Friday and post.
thanks,

I am having a similiar but different issue with a WIC-1DSU-T1-V2 on 1841 Cisco Router. I am following guide lines on-line per a WIC-1DSU-T1 (without V2) which is configured with service-module commands rather than controllers but I can't bring the status of the Serial 0/0/0 to up. Can someone explain to me what I am missing please. I've tried the following:
Interface serial 0/0/0
service-module t1 clock source line
service-module t1 timeslots 1-24 speed 64
service-module t1 framing esf
service-module t1 linecode b8zs
ip address 192.168.1.1 255.255.255.248
encapsulation ppp
fair-que
no shutdown
but only the following saves or shows up after a "show run":
"interface Serial0/1/0
ip address 192.168.1.1 255.255.255.248
encapsulation ppp
fair-queue
service-module t1 timeslots 1-24"
and here is the full "show int"
#show int ser 0/1/0put errors, 0

DCD=down DSR=up DTR=up RTS=up CTS=down
Thank you.

The issue with your Serial 0/1/0 is that your CTS is down because your DCD is down. Your DCD is down because the remote DSR is down. You need to look at the remote end to verify they are up OK....
