Need help configuring T1 on a blank cisco 1750 router
I went into an office today and found that a cisco 1750 had been wiped clean. The cause is unknown and there is no startup config or any backup file. I was given some commands from the ISP which are:
controller T1
framing esf
service-type data
clock source internal
linecode ****
cablelength long 0db
channel-group 0 timeslots 1-24
interface serial0
ip address * *
no shut
I only have my CCNA and haven't played with T1 before. I know how to configure the rest of the router but I'm stuck as to how to put in the given commands starting with "controller T1"
I typed
> enable
#conf t
#controller t1 or #controller t1 0 or #controller t1 0/1
and I receive "% Invalid input detected at '^' marker. " pointing to the 't' after controller
I have a simulator program and it shows that it is a valid command for the 1750.
So what's the problem?
What is the proper way to insert "controller t1"?
Will these commands be enough to get the ISP working, asumming that I put in the default route, nat, acls, and LAN?
Thanks for your time

cisco1750(config)#service-
^
% Invalid input detected at '^' marker.
this is Version 12.0(3)T if that helps.
I don't see service-mudule as one of the commands under config but I do see "controller" and "service"

Do you have a WIC-1DSU-T1 module in the router? If so, the service-module commands apply. They are applied under the interface configuration.
The defaults should work but you may need to set the encapsulation to PPP on the serial interface (up to your ISP).

I removed the card earlier to see if that would help and I took a picture incase I was asked.
It's a WIC-1T

Ahh, okay, you have an external CSU/DSU which is connected to the serial interface. The CSU/DSU config should still be in place (I assume) which is where the controller config applies. Simply add the IP address your ISP gave you to the serial0 interface and do a "no shut". See if the line comes "up/up" and try to ping the other end (your ISP). Double check with your ISP if you need to set encapsulation to PPP.
ASKER
for some reason the card is in slot 1 nothing is in slot 2.
I have a serial0 which I assume is the same as serial0/0 since there is no controller unit number

It's serial0. No controller config is necessary on the router itself. Simply configure the serial interface.
ASKER
what were the other commands for under controller t1 then? Someone else called the ISP so I didn't have a chance to ask.
controller T1
framing esf
service-type data
clock source internal
linecode ****
cablelength long 0db
channel-group 0 timeslots 1-24
The config file is basic, as in just out of the box, so are you sure I won't need these commands?
By the way, I've never received so many responses this fast before on EE. Thanks guys!

The controller commands are done on the CSU/DSU which in your case is external. If you look at the cable plugged into the serial interface on the 1700, you can follow it to the CSU/DSU. The CSU/DSU handles framing, line coding, channel assignment, etc...
I assume nothing happened to the configuration on the CSU/DSU and what your ISP gave you is typically defaults for a T1.
The only config necessary on the serial interface is the IP address, encapsulation (if not HDLC) and "ip nat outside", access-list if necessary.
You will need a default route obviously.

Correction :

I have a serial0 which I assume is the same as serial0/0 since there is no controller unit number

Does anyone have a possible explanation why I receive the following?
cisco1750(config)#controll
^
% Invalid input detected at '^' marker.

No encapsulation was specified by the ISP so I guess i'll try all of them.
I'm not at the office right now. I have to call someone to open up. There is a backup cable/dsl connection while i'm there so I can check back to this site. I'll be leaving in about half hour and it's 10 minutes away.
We are worried that there might be a hardware problem with the router.

Ok I went back to the office and tried to configure the serial interface last night. I entered the given IP address under s0 and no shut. I also entered the ip route 0.0.0.0 0.0.0.0 with given ISP gateway. The int s0 status was up/up, I was able to ping the default gateway but no other addresses (such as DNS servers). I tried all the different encapsulation protocols without the additional specs (i'm used to the 800 series). All were up/up except for ppp and smds which were up/down. I was never able to ping those servers. I'm going to call later and ask if they had any luck with the ISP and will go there later on.
I was asked to go in as a favor and probably won't be paid for half the hours. Now i'm in this to learn from the experience and see this through. If you have any links to online material where I can read up on the related concepts and commands, I would greatly appreciate it. I don't remember CCNA/CCDA covering anything at this level for modular bays and t1 commands. I still have a few months before CCDP.
Anyways, I'll update you guys with the latest as soon as I get back there. I think they were planning to replace the router already with an 1800 series.

Thanks for the link dkarpekin.
So here is the latest:
The office decided to buy an 1841 and has a WIC-1DSU-T1v2
Now the csu/dsu commands apply.
I started doing some of the commands and could have sworn I was able to ping the dns from a laptop after only putting the s0/0/0 ip address and ip route 0.0.0.0 0.0.0.0 *.*.*.* but as I added more commands I was never able to ping again.
I have received a more detailed list of neccessary commands from the ISP and will put them into the router tomorrow. I still didn't see any encaps.
I was able to start putting in the initial commands for service-module t1 I listed at the top.
I'm still not sure how to put service-type data or channel-group 0.
For cablelength my only option is short.
I was able to put timeslots 1-24 but don't know if there was any significance to it being on the same line as channel-group 0.
If I have trouble with configuring the 1841 I will post a separate question since it doesn't apply to this post anymore. I will be awarding points to this question now. Thanks for your quick responses everyone.
ASKER
Thanks again everyone. Please try to help if I post another question within the next 24 hours regarding the 1841 :)
