2Install the NTAK02 in any available slot 1-10 of the Option 11C Cabinet or slot 11-14 of Media Gateway 1.

3Install the NTAK19BA four-port cable on the 50-pin Amphenol connector associated with the slot the NTAK02 is installed in.

4If the installation is a dedicated mode using leased line modem configuration, the D-channel connects the DCHI with the far-end modem over a dedicated leased line. The modems must have a minimum transmission rate of 2400 baud and must support leased line capability and synchronous mode, 2-wire or 4-wire operation.

Modems such as Ventel 2400 Plus II can be used. You must specify 4-wire operation when ordering. Otherwise, the modem is factory shipped for 2-wire operation.

Note: The Hayes Smart modem 2400 cannot be used on leased lines.

5If the installation is a dedicated mode using dialup modem (such as Hayes 2400, Ventel 2400 or Gandalf 2400) configuration, the DCHI is connected to a modem that is connected to a 500 set line card. The call is connected to the far-end via the 500 set-to-TIE Trunk path.

Note: Dedicated mode using leased line modems is the preferred method.

6Set up the D-channel. Configure the modem at one end in the autodial mode so it automatically initiates a call to the other end at power-up. The autodial number must be coordinated with the far-end switch. The originating modem must have this autodial number stored internally as part of the modem configuration routine. The far-end modem must be configured for auto-answer.
