• Installed between the digital port and the BNC coaxial cable. See “Connect the
following adapter for E1-75 operations onto the digital port: RJ-48 to E1-75 dual
BNC adapter cable (Ordering part number:
AG2CA0001).” on page 3-15.
Cables Use BNC cables for E1-75 connections on a single or dual port T1/E1 interface card that
has been configured for E1-75 operations. Two BNC cables are required for each
interface card, one for the receive side and the other for the transmit side.
► To connect the BNC cables:
1.
Connect one end of each cable to the BNC connectors on the interface card,
respecting the transmit (TX connector) and receive (RX connector) requirements for
the cable terminations.
2. Connect the other end of each cable to the network or the BNC connectors on another
interface card set to E1-75. Once again, select the TX or RX connector according to
your application requirements.
3. Provide adequate strain relief for the cables, as described in the Caution below.

Caution
The adapter and attached BNC coaxial cables require strain relief to
ensure that they do not loosen from the digital port:
-If the unit is mounted in a rack,
you must secure the cables to a side
rail using tie-wraps, or support the weight of the cables on a tray
-If the unit is on a table, you must support the weight of the cables
on the table
.
The digital port can desynchronize and the unit reset if the full weight of
the BNC coaxial cables is unsupported.
