I have a 7206 router with 6 T1 lines bound together in a multilink.
3 are on a 4 port T1 controller card, the other three are on a serial port card with CSU/DSUs.
I am going to change out the CSU/DSUs for another T1 controller card.
The existing T1 controller has all three T1s on channel-group 0.
When installing the additional T1 controller, do I create a new channel-group or can I add the new T1 controllers to the same channel group?
All six T1s need to bind together
