Fractional T1 help needed

| I am using Cisco 2600 routers with T1 CSU/DSU WIC's. I can't seem to get the link up using ppp. Can someone share a base config for the serial interfaces that they know will work? Thanks in advance.

| How many routers do you have?
What type of cable are you using?

| Sorry, real world unfortunately. I have a feeling it is the carrier having an issue after the latest hurricane that blew through here. 2 Routers, both 2600's. The circuit is a fractional T1 256k. | |

| when you do a show int s?/? what is it showing | |

| "up down" which usually is a carrier issue. But I want to be sure with my config. | |

| unlikly your config, it would be better for you to paste the config in of your serial i/f's

| interface Serial0/1
description connection to Firestation9
ip address 172.16.11.1 255.255.255.252
no ip directed-broadcast
encapsulation ppp
no ip mroute-cache
The other interface is the same except the IP address is .2
It has been a while since I have needed to setup any T1's, but correct me if I am wrong, the service-modules are default and should be fine. PPP is pretty basic right? | |

| looks like a cct problem to me mate, report it out.
That will be £50 please?
onnnnly joking | |

| If this is a fractional T1 you will also need to specify how many timeslots are being used. If using 384K for example it would be service-module t1 timeslots 1-6.

| Believe you would be down/down if the channels were mapped wrong.
