The following prerequisites apply to your network:
■
To use both B channels together, the destination must be running
Multilink PPP, either on the NETBuilder bridge/router with a built-in
ISDN port or on the TA.
■
If you use built-in ISDN ports and ISDN TAs in the same dial pool, and
you are using Multilink PPP on the SuperStack II bridge/router, you can
use the TA at only 56 or 64 Kbps.
■
When using a dial pool, you cannot accept phone calls from other
vendors’ bridge/routers.
