Rt Equipment; 500-22-00 Icis-1 Isdn Interface; 500-22-00 Icis-1 Isdn Interface Connector Pin-Outs - Trilogy Communications Commander Installation Manual

7.3 RT EQUIPMENT

Radio Talkback equipment may be supplied by Trilogy as part of a complete system. It is not
manufactured by Trilogy and will be supplied with the original equipment manuals.
The usual configuration consists of one or more Base Stations and a number of portable
transceivers. The Base Stations are connected to the matrix using normal 4 wire audio ports
according to the pin-out information in Section 2.

7.4 500-22-00 ICIS-1 ISDN INTERFACE

The 500-22 ICIS-1 ISDN interface is connected in the same manner as the Telos Hybrid
(see Section 0). The 1U package contains two 64k-bandwidth channels, which may be used
independently or as a single ISDN2 (128k) bandwidth channel.
To make correct use of the available bandwidth, two separate telephone interface cards
(500-19-10) should be allocated, along with two matrix ports. It is possible to request two
independent incoming telephone numbers, either via your in-house switchboard of (if
appropriate) from your telco. In this way, incoming calls can be directed to either Bearer 1 or
2 and outgoing calls will be connected to the first available Bearer. Careful programming
within the telephone groups area of PathFinder is required to obtain the best results.
