• E1 (120-Ohm RJ-48C and dual 75-Ohm BNC connectors)—ME231A-R2
Connect the serial cable to the Black Box serial port as follows:
1. Attach the male connector of the serial cable to the female serial connector on the
Black Box.
2. Attach the other end of the cable to the serial connector on the local serial NTU.
NOTE: You can connect the V.35 interface to an M/34 connector using the interface
adapter.

E1 line or supply the network clock for the E1 line.
