ERICSSON
TELEPHONE No's N1046 - N1049

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 for internal signalling (N1046 and N1049 only), a ringer for exchange calls (extension calls operate a ringer in the wall case) and a dial, normally of  P.O. pattern, but other types can be fitted.

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.

A maximum line loop resistance of 800ohms ensures satisfactory working.

Battery calling between telephones can also be supplied and these telephones have Code Nos. N1047H (intermediate) and N1048H (extension).
