50-Pin Connector and Cable

Figure A-1 illustrates the cable pinouts for the Security Module female connector and the 50-Pin cable male connector. This figure also shows how to connect Port 1 of the Security Module to a desktop transceiver using the TIA-568A wiring standard for an RJ-45 connection. Connections between the module and the desktop device can be made through a patch panel, Hydra cable, or punchdown block. It is critical that the data path be preserved along the route from the module's Telco connector to the remote end, especially when going through patch panels or punchdown blocks.
