VOICE TERMINAL MODULE
The Voice Terminal Module, color-coded blue, occupies position 9 (labeled Intercoms 10 to
19). Up to six additional Voice Terminal Modules can occupy positions 10 and 11 in the
Model 1030 control unit, and positions 21, 22, 23, and 24 in the expansion unit. The seven
Voice Terminal Module positions are labeled on the colored bands
on the control unit and the expansion unit with intercom
designations (Intercom 10 to 19, Intercom 20 to 29, etc., through
Intercom 70 to 79) in addition to position numbers 9, 10, 11, 21,
22, 23, and 24. Each Voice Terminal Module provides connections
for 10 voice terminals via 4-pair modular jacks (only jacks 0 and 5
are numbered). Both the module position and the jack number
determine the intercom number for each voice terminal. For
example, the voice terminal connected to the third jack from the
top in position 11 (labeled Intercoms 30 to 39) is number 32.
BASIC TELEPHONE MODULE (OPTIONAL)
Basic Telephone Modules are interchangeable with Voice Terminal Modules and occupy the
same positions (except for position 9). These modules allow for connection of basic Touch-
Tone and rotary telephones to the MERLIN system via modular jacks. Advanced features are
available through dial-access codes (see User's Guide for Basic Touch-Tone and Rotary
Telephones). A Ring Generator Unit must be connected to the Power Module to provide
ringing current to the telephones connected to the Basic Telephone Module.
