Caution To prevent damage to the system, make certain you connect the BRI cable to the BRI connector only and not to any other RJ-45 connector. The Ethernet, Token Ring, and BRI ports all use RJ-45 connectors.

Note All serial cables have a DB-60 connector on the end that attaches to the AccessPro card. The following pinouts represent only the network ends of the cables. Because the pins on the DB-60 connector are small, manufacturing and soldering these cables yourself might be very difficult and is not recommended.


Note In the following tables, serial pinouts for DTE and DCE cables use arrows to indicate signal direction: ---> indicates DTE to DCE, and <--- indicates DCE to DTE.
