Whats a difference between a simple 2 Mbps link, & a E 1 link. Can we have a Channelised E1 without ISDN signalling? Also , do we use full 2Mbps bandwidth for our use or some amount is used as in E1 ISDN links.
Please clarify.

Both use 32 64k timeslots,
isdn uses 30 channels for data, 1 for signalling and 1 for framing.
E1 has no signalling , 31 for data and 1 for framing.
Have a search for g.704 for more

Sorry for late response.
Acc to ur reply 30*64kbps is the actual total bandwdith for ISDN PRI, & 31*64kbps is teh actual bandwidth for E1 using G703. Also I read somewhere that E1 G703 can be of two type Framed & Unframed. Perhaps Framed E1 has CRC4 and hence it will provide even less bandwidth in total for data transfer.
Am I right ? Please explain.

have a look at the following http://www.sunrisetelecom.com/technotes/TEC-GEN-1B-E1.pdf should explain it better than me.
