Broadband Network Modules
The BNM card set provides the MGX 8220 trunk interface to a BPX 8620 node. There are two major
types of BNMs, one supports a T3 or E3 trunk and one supports a 155 Mbps SONET SMF trunk.
Each MGX 8220 shelf must be equipped with at least one BNM installed in slots 1 or 2. A second,
redundant, BNM may be installed also in slots 1 or 2. The primary and the redundant BNMs must
be of the same type. Each BNM installed consists of a front and back card set.
BNM-T3/E3
The Broadband Network Module-T3E3 (BNM-T3E3) is a two-card set consisting of a BNM-T3 or
E3 front card and a T3E3-D-BC or T3E3-B-BC back card. Either back card can be used with either
front card except that the BNC clock connector only works for E1 clock sources. The shelf may
contain a single BNM card set or a dual (redundant) card set. The cards are installed in slot 1 and/or
slot 2.
An illustration of the BNM-E3/T3 card set is shown in Figure2-13.
