Lock the connector into place with the bail latches.

Attach one to four modems to the connectors at the opposite end of the cable.

If you want to place the modem farther away from the system, attach a BC22F extension cable between the cable assembly and the modem

(see Figure 2–23).

Refer to the modem documentation for the location of the connector, and for instructions on using the modem.
