How to unframed E1 Controller in IOS ver 15.1?

Dear friends,

We've just bought Cisco 1900 series, we encounter a few problems

1- The IOS version is different from our previous router. Previous version

is 12.4 , our new router is version 15.1

2- Below is our previously working config for controller . The channel

group must be unframed

!

controller E1 0/0/1

channel-group 0 unframed

!

3- Hoewever the config below is from our newly bought 1900 series IOS ver 15.1 .

However they do not support unframed format. How can we solve this

problem.

!

controller E1 0/0/0

channel-group 0 timeslots 1

!

To support E1 unframed you need the more expensive G703 version of VWIC card, or a data-only E1 card. Regualr VIWC versions do not support unframed E1.

This is an hardware decision that Cisco has made, and has nothing to do with IOS version or configuration.

Note: even if the circuit is delivered unframed, if the other end is using 31 timeslots, it will work fine (1984 Kbps).

Configure both sides for 31 timeslots, and it will work fine.

Can I group two fisical controller E1 (2048 mbps) in one 4 mbps Logical Interface?

I need to do something similar to "Etherchannel", but with E1 interfaces...

The sh run is...

--------------------------------------------------------

  controller E1 0/2/2

clock source internal

channel-group 1 unframed

!

controller E1 0/2/3

clock source internal

channel-group 1 unframed

------------------------------------------------------------------

How can I group that two controller in one?

thanks
