Troubles configuring T1

matt_drmmer
Level 1
Level 1

Hi - I am trying to bring up a new data T1 for us and I seem to be running into some issues. I am trying to connect it to the same router that our ISP hands off a metro ethernet circuit to us but the router just will not take the configuration. The router has 2 WIC's installed but it does not show them in the configuration. I think I might just be missing some really simple setting so hopefully someone here can assist. Here is a snippet of the configuration and information from the router (cleaned), any assistance would be greatly appreciated.

What WICs don't show in config? You have two already. Please send output of "show diag" to see what's installed in the router.

Thank you for replying, I am pretty much stumped and at a loss on this. The WIC's do show up but I cannot configure them, when I enter into configure terminal mode on the router and type controller it does not return anything for example;

RTR01#conf t

Enter configuration commands, one per line. End with CNTL/Z.

DHQ-MOE-RTR01(config)#controller T1 0/1

% Invalid input detected at '^' marker.

RTR01(config)#controller ?

RTR01(config)#controller T1 ?

Here is the output from the show diag command;

It just seems strange that I cannot configure the T1 controller on thie router. Thank you once again for any insight.

Matt:

I may be wrong, but I think the 2600 utilizes a 'controller' in its newer T1/E1 Voice WAN Flex WIC cards with IOS Software Release 12.0(5)XK, 12.0(7)T or a later, not the legacy T1 CSU/DSU WIC cards.

Instead of trying to enter controller mode, try going into interface configuration mode and use the following commands to configure the framing, coding and clocking for the T1.

Example:

interface s0/0

and then enter one or more of the following:

-service-module t1 clock source line

-service-module t1 data-coding normal

-service-module t1 timeslots all speed 64

-service-module t1 framing esf

-service-module t1 lbo none

-service-module t1 linecode b8zs

Matt:

A quick clarification...

After reading my post, I realized that you may misinterpret what I wrote as a recommendation for how to actually configure the interface. It wasn't. I was just trying to show you examples of what kind of configurations can be made from that mode.

I assume you know which features you want configured and what to configure them for. If you need help with that, come back.

So, under interface s0/0, try doing a "service-module t1 ?" to find out all the options that are available to you.

Thanks

VL

Victor - Thank you very much for the link, I read through it and did a test on my router and the commands work exactly how you described so that must be what is going on. The only thing that I don't quite get is although I can run those commands, when I look at the running configuration after the commands do not appear. This is what it looks like;

RTR01#conf t

Enter configuration commands, one per line. End with CNTL/Z.

RTR01(config)#int S0/0

RTR01(config-if)#service-module ?

t1 T1

RTR01(config-if)#service-module t1 ?

clock Service module clock source

data-coding Service module DCE line coding

fdl Specify the FDL standard for a DS1 data link

framing Framing format

lbo Line Build Out format

linecode Line coding format

remote-alarm-enable Remote/Yellow alarm enable

remote-loopback Remote Loopback/RL disable

timeslots Fraction timeslots

RTR01(config-if)#service-module t1 framing ?

esf ESF format

sf SF format

RTR01(config-if)#service-module t1 framing esf

RTR01(config-if)#service-module t1 linecode b8z

I will need to contact the vendor and see about scheduling a time that we can turn up the T1 to see if perhaps the commands appear when the circuit is live. Thank you again for the help, I really appreciate it.

Hi, commands that doesn't appear are default.

To see how's the T1s are doing, "show service-module serial".

Matt, you're welcome.

Paulo is right, default settings sometimes do not appear in the running configuration.

If you notice in the document, the running configuration shows that the serial interface was configured for SF framing and AMI coding, which are different than what you configured. So, perhaps ESF and B8ZS are the defaults.

Anyway, you can easily verify your configuration by using the show service-module serialX/Y command.

Have a great day.

Victor

Thank you Paulo and Victor, that works like a charm, and as always I have learned a ton. I really appreciate all of the help from you folks.

No sweat, thanks for the nice rating and good luck!
