The TAMB2 telephone paging access module provides a
means of interfacing various analog telephone port types to
a paging system amplifier to enable a facilityʼs telephone system
to be used to make audio announcements over its paging
system. The TAMB2 will interface to analog loop start and
ground start trunk ports as well as analog ring-up station lines.
It provides a means of connecting an external audio or music
source that will play over the paging system when no pages
are in progress. A set of contacts are provided to signal external
equipment of the TAMB2ʼs operational status. Various DIP
switches and controls provide a wide range of flexibility over
how the access module will operate. The TAMB2 can be
mounted on a wall, mounted as a single unit in a rack (optional
rack mount kit required) or mounted 2-up, side-by-side in a
single rack space.
