ERICSSON TELEPHONE No. N1320


C.B. Intermediate Telephone

n1320a.jpg (9665 bytes)Black enamelled steel case with Bakelite cradle stand, Bakelite micro-telephone, four position switch, indicator, 3-magnet generator, 1000 ohm ringer, induction coil and two condensers.

The wall case is fitted with a 1000 ohm ringer and the necessary connecting terminals.

Connections between the exchange, the intermediate telephone and the extension telephone any two of which can be connected together are made according to the position of the switch which should, normally, be left in the position marked "normal"; calls from the exchange will then ring the bell in the telephone and those from the extension, the bell in the wall case.

A ring will, however, be received at the intermediate station from either the exchange or the extension, irrespective of the position of the switch.

The indicator shows when the exchange and the extension are in communication, and the generator is for signalling the latter,
