Attaching JT2 Port Adapter Interface Cables
The 75-ohm coaxial cable (see ) required for the connections to PA-2JT2 are not available from
Cisco Systems; they are available from commercial cable vendors. Use only 75-ohm coaxial cables for
all PA-2JT2 connections. (For specific cable requirements, refer to the section “
Interface Connectors and Cables
Note
We recommend that you attach the ferrite sleeves included with PA-2JT2 to all 75-ohm coaxial cables
you plan to use for your PA-2JT2 connections. Attach each ferrite sleeve as close to the port adapter end
of each 75-ohm coaxial cable as possible.

75-Ohm Coaxial Cable with Ferrite Sleeve Attached
Each E1-G.703/G.704 interface requires separate receive and transmit connections to an external B-type
or C-type DSU. A DSU is available from outside vendors.
Use the following procedure to connect the 75-ohm coaxial cables to the JT2 port adapter:
Step 1
Attach the 75-ohm coaxial cables directly to the BNC ports on the JT2 port adapter. Attach one end of
a cable to the port labeled TX0 and one end of a second cable to the port labeled RX0. (See .)
