TCAS Connections
From Zenitel Wiki
This article describes connection details of the analog intercoms TCAS-1, TCAS-2 and TCAS-3.
Wiring
The cabling from the AlphaCom server to the intercom station is star wiring. Two twisted pairs of wires are required. The maximum distance depends on the cable diameter:
- 0.5 mm wires: 1.4 km
- 0.6 mm wires: 2.0 km
- 0.9 mm wires: 4.0 km
The station line is connected to the station by means of an RJ45 connector at the rear side of the station, or optional by using the plugable screw connector.

The station cable is not a 1:1 cable! |
For details on connection at the AlphaCom server side, see ASLT - AlphaCom Subscriber Line Board
Second Call Key
The station is prepared for a future second call key (DAK2).
This second call key can be found on the print if wanted and utilized with an external call button.
- A second external call key must be connected between the A-wire and the lower leg on D6 (highlighted in the image above).
