Can some give me detail instructions on how to configure two WIC-1DSU-T1-V2 in two different 2811 routers. I will be using a T1 crossover cable but I'm not sure if I need to configure the following entries for the serial interface:
Interface serial 0/0 service-module t1 clock source internal service-module t1 timeslots 1-24 speed 64 service-module t1 framing esf service-module t1 linecode b8zs ip address 10.1.1.1 255.255.255.0 encapsulation pppfair-que no shut
Can someone break down what each line means in the configuration above? Thank you so much in advance!
Your config should be as below:
service-module t1 timeslots 1-8 speed 64
you can use the above command, implies that you are using fractional T1..
Hope this helps
Pls rate useful posts.
On a back-to-back configuration, one router will provide the clocking, the DTE end - while the other router will follow the clock, the DCE end.
Per your configuration, both devices will use their internal clocking. I recommend having one set to line (DCE) and the other to internal (DTE).
service-module t1 clock source internal
service-module t1 timeslots 1-24 speed 64
service-module t1 framing esf
service-module t1 linecode b8zs
ip address 10.1.1.1 255.255.255.0
First line means to use the internal clocking from the router. Usually seen at the DTE side
Second line means to use 24 channels at 64Kbps each. That gives you a T1.
Third line and Fourth line, framing specified by the telco and linecode. Standard config in USA
