TELEPHONE No's N1321, N1322, N1326 & N1327

C. B. Telephones

This intermediate set allows an extension the use of the exchange line, as well as intercommunication, and is ideal for the executive with secretary.

The switching mechanism consists of four inter-acting push-button keys in the top panel above a window through which "engaged" is displayed by the operation of an indicator-relay during extension-to-exchange conversations.

Other fitments include an "alnico" generator, a 1000 ohm ringer operated from the exchange, induction coil, condensers and micro-telephone, all of standard design and proved efficiency. Calls from extension operate a similar ringer in the Bakelite wall case.

Extension-to-exchange calls can be made secret or non-secret from intermediate and an audible signal at their conclusion can be arranged if desired.
