Setting up the D-channel

If this is a dedicated mode installation using leased line modems, the D-channel connects the
DCHI with the far-end modem over a dedicated leased line. Synchronous modems with a
minimum 2400 baud data rate must be configured. Modems must support leased line capability
and synchronous mode. The Hayes Smartmodem 2400 cannot be used on leased lines.
If this a dedicated mode using dial-up modems, modems such as Hayes 2400, Ventel 2400 or
Gandalf 2400 can be used. In this configuration, the DCHI connects to a modem which is
connected to a 500 set line card. The call connects to the far-end through the 500 set-to-TIE
trunk path.
Program the modem at one end in the auto-dial mode, so it automatically initiates a call to the
other end at power up. The auto-dial number must be coordinated with the far-end switch. The
originating modem has this auto-dial number stored internally as part of the modem
configuration routine.
The far-end modem need only be set up for auto-answer.
