QUICK GUIDE TO THE TELCO / CODEC MODULE
Three connectors come standard on the optional Telco module: one 6-pin analog audio input connec-
tor, one 3-pin digital audio input connector, and one 24-pin logic connector. The connectors are hidden
by the meter panel in normal operation.

OGIC I/O — The 24-pin logic connector allows control of the connected
device by the module, or external control of the module by the device. When
the device connects to the module through a switcher (router or External
RLS), source selection addressing is output from this connector. The source
(analog or digital input), whether a switcher is used and other logic selections
are configured by the SETUP DIP switches (see Switch Definitions, page 2-
25). For additional module information, see pages 2-26 and 2-27.
