AUTOMATIC REPLY AND CALL BATTERY RINGING
TELEPHONES (SIDE STATIONS)
Reply and Call Wall Telephone, fitted with Standard Pattern Hand Combination (No. U 175 ), Call Bell, etc. The "Sterling" Automatic Reply and Call System has been designed for cases where it is not desirable or convenient to
use a Central Station Annunciator Switchboard. It is, generally speaking, most useful where the Principal wishes to call all the
outer offices, and vice versa. |
