hello johnny,


sample config of a T1 is as below:


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 ppp

fair-que

no shut


make sure the framing and linecode are configured right. check this with the ISP... if your LAN is on a private range, you also might need to do a NAT/PAT over the T1 interface.. for NAT examples refer to the CCO. you also need a default route to the outside towards the t1 interface...


Hope this helps.. all the best. rate replies if found useful..

thatnk you Raj, yes, the config you shared is familiar to me from a poit-to-point i worked on. i am concerned with the intra net behind the t1 which is a static ip network but private nonetheless. thank you again.

cool. if u gotta private network, obviously you will do a nat/pat out the T1 connectivity.. thanks for your response.. mark the case as solved (if it solves ur query), which can be useful for others when searching.. rate replies if found useful..
