E1 issues, D-channel on serial....

umar.osu
Level 1
Level 1

Hi folks....

I am trying to setup a home lab where i have a PSTN router which provides E1 connectivity to two other routers (preparing for CCIE). I have no experience in setup up an E1 connection from the PSTN side hence facing issues.... i have checked some initial configuration (INE lab), which i am using as configuration model for my lab setup and D-channel is setup using serial x/x/x:15.

I am trying to do the same but i dont get that interface enabled. Below is my configuration.... Please suggest what i can do.... to setup this lab....

If you want to use your E1 interfaces for voice calls then you need to configure them with pri-group, not channel group.

eg...

  controller E1 0/0/0

  pri-group timeslots 1-31

interface Serial0/0/0:15
no ip address
encapsulation hdlc
isdn switch-type primary-net5
isdn incoming-voice voice

The next thing is if you want to configure one end of the E1 as clock source because I see that you have set the clock to internal, then you need to make that end the network side..using the isdn protocl emulate network command...
