Re: DDR -backups using one E1 card.

Looking at eg1 and eg2, only one pri-group can be created where as many channel groups can be created.

Does this mean two E1 interfaces are needed for ISDN backup of the two different serial lines in question?

----------------------------eg 1

controller E1 0

framing crc4

linecode hdb3

clock source line primary

pri-group timeslots 1-31

----------------------------eg 2

controller t1 0

channel-group 0 timeslot 1-6

channel-group 1 timeslot 7

channel-group 2 timeslot 8

channel-group 3 timeslot 9-11

pri-group timeslot 12-24
