To access Trunk 1, Trunk 2, or both Trunk 1 and Trunk 2, connect a shielded T1 or
E1 RJ-48 cable to one or both 8-pin modular jacks.
To access all four trunks, use the two trunk adapter cables (NMS P/N 32851). Each
trunk adapter cable separates the 8-pin modular jack on the end bracket into two
RJ-48C connectors.
The following illustration shows the trunk adapter cable:
