Procedure 43
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.
There are two modes of ISDN Signaling Link (ISL) operation, shared mode
and dedicated mode.
