Can I configure G703 on a subset of E1's timeslots

Hello.

I need to cennect a cisco router to an external device. This connection must be based on G703, but also this connection should not exceed 1Mbps.

Can I configure the router to run G703 not on the whole E1 but on a certain channel-group (which will be constructed from timeslots 1-16) ?

If yes: 1) On which cisco routers can I do so ?

2) Do I have to use a specific card that supports this kind of configuration ?

3) Can someone provide a sample configuration for this ?

Thank you.

Boaz.

Re: Can I configure G703 on a subset of E1's timeslots

Am not sure what you mean by G.703 but a router with internal CSU DSUs supports 2 types of E1 ckts - framed (g.704) and unframed (g.703) - the unframed ckt is for the whole 2.048Mbps pipe cannot be channelized. If you need to channelize then need to use G.704 - the routers that support both these E1 ckts are 26/3600s and 72/7500s

for the 26/3600 - VWIC-1MFT-G703

for the 72/7500 - PA-4E1G-75 or 120

Thank you for the answer.

So, I will need to use G704 framed E1 ? Is this a character of the router interface or of the PSTN line (or both) ?

How do I configure this kind of connection ? What do I have to add to the following configuration :

controller E1 2/0

channel-group 1 timeslots 1-16

interface serial 2/0:1

ip address x.x.x.x y.y.y.y

Thank you.
