Hi,
For the past few days I've been attempting to configure a data T1 on a Cisco 1760, but I'm stuck at:
Serial0/0 <our ip address> YES NVRAM up down
To provide a bit of background. This router used to be configured with a T1 via Frame-Relay; which worked
fine. Now we recently change offices and providers, and the provider did not offer any information as to which
encapsulation type to use, and if Frame-Relay which DLCI to use, etc.
Now I've been trying to setup the T1 connection and testing various settings such as encapsulation HDLC
and PPP, but no luck. I also played around with the line codes and framing; which resulted in the following
framing sf int down, line prot down, framing esf int up, line prot down. Regardless no luck.
Now I've been following several guides and examples mainly the following:
http://www.cisco.com/en/US/docs/ios/12_2/12_2z/12_2zl/feature/guide/t1dsu.html#wp1032260
In this guide they make mention of a WIC-1DSU-T1-V2, but as you can see in the show diag snippet at the
bottom; we have a WIC-1DSU-T1 version 1.5. I dont' know if this poses a problem for us.
Throughout the entire process I've seen a few irregularities for example:
1. Router(config-if)#service-module t1 cablelength short 110ft
^
% Invalid input detected at '^' marker.
The IOS doesn't recognize any command with service module t1 ca , and the only recognized command with
C is clock.
2. If I enter the following list of commands under the serial interface:
!
interface Serial0/0
ip address 10.0.0.51 255.0.0.0
service-module t1 framing esf
service-module t1 linecode b8zs
service-module t1 timeslots 1-12 speed 64
service-module t1 data-coding normal
service-module t1 cablelength short 110ft
service-module t1 remote-loopback full
service-module t1 clock source line
!
And I do a sh run all I get is the following:
!
interface Serial0/0
ip address 10.0.0.51 255.0.0.0
load-interval 30
!
Although i can do a show service-module s0/0 I can see all of the configured parameters (see below)
Module type is T1/fractional
Hardware revision is 0.128, Software revision is 0.2,
Image checksum is 0x73D70058, Protocol revision is 0.1

I'm a little bit rusty on my Cisco configs, so if you see anything unconventional or out of the ordinary please
don't hesitate to point it out.
Thank you,
