ATM-T1 is for ATM over a IMA circuit (Inverse Multiplexing)
Look for IMA on CCO. Basically IMA allows you to have ATM as
your transport over a DS1 (T1).
BRI - Basic Rate Interface - is used for ISDN 2B1D channels. This is for
q931,q921 signalling. ISDN is digital dialup (basically). The channels are
2*64K (B channels) and 1 16K D channel. The B channels can be setup via your
provider in the following configs:
1B voice
1B voice/data
1B Data
The D channel is often used just for signalling but other uses for this do
exist.
Hope this helps.
