T1/E1 and T3/E3 - configuration

HI,

AM little confused on the terms T1/E1 and T3/E3

As far as I am concerned there are T1/E1 and T3/E3 in ISDN. And there
are T1/E1 and T3/E3 in our normal leased line connection (inter office
WAN link connection) where we are not using any ISDN service. What is
the difference between these two??

===================================================================
Secondly I have seen the configuration commands

Interface controller t1 0/0
Pri-group / channel-group
Clock
Framing
Line code


Interface serial 0/0 :23
Ip addrss


My question is that is that is enough for a T1/E1 configuration. And
why in some configurations   Pri-group and in some other configurations
channel-group is configured. What is the difference between these two?

Thanks,

dabance
