2 Install the NTAK02 in any available slot 1-10 of the Option
11C Cabinet or slot 11-14 of Media Gateway 1.
3 Install the NTAK19BA four-port cable on the 50-pin Amphenol
connector associated with the slot the NTAK02 is installed in.
4 If 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.
5 If 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.
6 Set 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.
