| Automatic Intermediate Telephone
The wall case is fitted with the necessary connecting terminals and a 1000 ohm ringer. Connections between the exchange, the intermediate telephone and the extension telephone, any two of which can be put into communication 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 the exchange or the extension, irrespective of the position of the switch. The indicator shows when the exchange is speaking with the extension, and the generator is for the purpose of signalling the latter.
