Broadband Network Interface Cards (BNI-T3 and BNI-E3)
The BNI-T3 and BNI-E3 interface the BPX switch with ATM T3 and E3 broadband trunks, respectively.
These ATM trunks may connect to either:
•
•
•
The BNI-3T3 back card provides three DS3 interfaces on one card. The BNI-E3 back card provides
three E3 interface ports. The BNI back card types are very similar, differing only in the electrical
interface and framing.
Any of the 12 general purpose slots may be used to hold these cards. Each BNI operates as a pair with
a corresponding Line Module back card.
