and is defined in the H.323 Endpoint Parameters settings. The
Address Book - Endpoint Definition dialog box contains the
Destination Identifier whose configuration is set to H.320 endpoint
and is defined in the H.320 Endpoint Parameters settings. The H.320
Endpoint Parameters settings define the Phone Number and Bonding
Phone number.
Step 3. The remote gateway retrieves the endpoint ISDN number from the
Address Book table and connects the call.
H.320 Endpoint Over an H.323 Backbone to H.323 Endpoint,
Using Profile (with TCS4)
The H.320 endpoint connects using the following string: [ Dial-in No. , Link
DID ]^[ Alias ], for example, 43218071^222.

TCS4)
Step 1. The H.320 endpoint dials the MCU/gateway prefix, Link DID and
Alias.
The digits 4321 represent the Dial-in number defined in the Network
Service Properties, 8071 is the Gateway Link DID taken from the
Gateway Link. The Gateway Link DID contains the Dial-in number
entered in the Network Service (ISDN), ^ is the TCS4 indicator and
222 the alias (in E.164 format) of the H.323 endpoint.
