Connection to Telephone Exchange

Telephone System must intercept telephone lines coming from the telephone exchange to the dwellings
of the building. Telephone Lines interception point depends on the installation:
- Installations provided with a 50 way connector intercepting the telephone lines.Usually another
connector is plugged to short the lines. A 40 Way Cable (Cod. 93645) which connects the
Telephone System with the relay cards is used. The system is sized to handle 10 apartments
each relay card.
- Installations without the 50 way connector. Telephone lines going to apartments must be
intercepted by means of a 50 way flat wire (Cod. 90549)
