RE: G.703 -> V.35 Compatibility

So looks the problem is happened between two service providers.

The v.35 modem should be placed or you can not insert G.703 cable into
V.35 interface. :-)

If it is concerned that the modem is a point of root cause, you may try
to install another E1 card in this router and remove V.35 modem for
testing.

Make sure your router in E1 end has similar configuration like below.
The v.35 end has not special settings.

Configurations

====================================

card type e1 0 1

controller E1 0/1/0

 channel-group 0 unframed

====================================

Regards,

Jerry

Dear Jerry,

The SP put the modem as unframed - the line protocol still wasnt coming
up.

The loop test on the entire circuit and each segment seperately was done
successfully, but still not line protocol.

Do you think the converter is needed here?

Regards,

Ranjith Samuel.
