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

It's been many years since I've worked on one of these, so here goes. The reason that your configs don't show up is more than likely because they're at default. Do you know what your encapsulation is supposed to be set up as? By default, HDLC is chosen. If you're needing ppp, this would explain the "up/down" status that you're seeing.
What's on the other side of this link? Is it a provider or another router that you have control over?
HTH,

Hi Blakley, thanks for your help.
This router is connecting to an ISP. No I tried configuring encapsulation as PPP, but no success.
Now the ISP didn't provide any details about encapsulation, framing, line code, etc. They just provided
us the assigned ip and the gateway ip.
11-19-2012 02:22 PM
You should contact them to see what the specifics are. You'll know what to do after you get this information, and it would help us further.
Can you find that information out?
11-20-2012 10:18 AM
Hi Blakley,
I was just contacted by the guys at the ISP, and the encapsulation type was a FrameRelay,
so I'm guessing that I was not even close in My configuration.
It's been a while since I've setup a T1, and a friend of mine has setup multiple T1 with several
ISP here, and most of them have all been PPP, so I guess I assumed that frame relay was
not being used much lately, but I guess I was wrong.
Anyway I'll finish the configuration and post back my results.
Thank you,

Hi,
I'm attempting to configure the frame-relay t1, but I'm stuck at interface up, line prot down.
Now I've applied the following configuration:
interface Serial0/0
ip address
encapsulation frame-relay
service-module t1 timeslots 1-24
frame-relay interface-dlci 100
sh service-module s0/0:
Module type is T1/fractional
Hardware revision is 0.128, Software revision is 0.2,
Image checksum is 0x73D70058, Protocol revision is 0.1
Receiver has no alarms.
Framing is ESF, Line Code is B8ZS, Current clock source is line,
Fraction has 24 timeslots (64 Kbits/sec each), Net bandwidth is 1536 Kbits/sec.
Last module self-test (done at startup): Passed
Last clearing of alarm counters 00:17:17
loss of signal : 0,
loss of frame : 0,
AIS alarm : 0,
Remote alarm : 2, last occurred 00:10:10
Module access errors : 0,
Total Data (last 1 15 minute intervals):
0 Line Code Violations, 0 Path Code Violations
0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins
0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs
Data in current interval (138 seconds elapsed):
0 Line Code Violations, 0 Path Code Violations
0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins
0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs
ISP provided data:
Which is basically what the ISP provided, but as it appears I must be missing something.
Any ideas?
Thank you,

Try this configuration:
interface Serial0/0
encapsulation frame-relay
int s0/0.100 point-to-point
ip address
service-module t1 timeslots 1-24
frame-relay interface-dlci 100

Hi, Blakley, thank you for your help again.
I tried exactly what you said with one exception; which is that the IOS didn't like me specifiying the timeslots in the sub interface, so I moved it over to the interface.
Configuration:
!
interface Serial0/0
no ip address
encapsulation frame-relay
service-module t1 timeslots 1-24
!
interface Serial0/0.100 point-to-point
ip address
frame-relay interface-dlci 100
!
I bouced the interface, but the end result was int up, line prot down.
12-05-2012 04:56 PM
Let's try this:
Post "show frame-relay lmi" and "debug frame-relay lmi" results..
HTH,
John
*** Please rate all useful posts ***
12-05-2012 05:33 PM
The show frame-relay lmi returned the following:
LMI Statistics for interface Serial0/0 (Frame Relay DTE) LMI TYPE = CISCO
Invalid Unnumbered info 0 Invalid Prot Disc 0
Invalid dummy Call Ref 0 Invalid Msg Type 0
Invalid Status Message 0 Invalid Lock Shift 0

FYI I have just reloaded the router because I was doing some hardware loopback tests.
As a result of the debug the router printed out the following:

Try changing the lmi type to ansi and see if it will come up. You may want to put your original config back in, so copy paste this in:
no int s0/0.100
interface Serial0/0
encapsulation frame-relay
ip address
frame-relay interface-dlci 100
service-module t1 timeslots 1-24
frame-relay lmi-type ansi

Can you post the running config? Generally, the problem with up/down is either the incorrect encapsulation or a problem with the configuration between you and the isp. LMI type mismatch is one cause of this.
