Phone Patch
The SLR 5000 Series Repeater is capable of multi-mode telephone interconnect through the Zetron
Model 30 Phone Patch. The Zetron Model 30 Phone Patch interconnects to the repeater and allows
users to initiate and receive land line telephone calls through the subscriber radios. When properly
configured, subscribers can initiate and answer telephone calls. Through selective signaling, calls from
land line users can be directed to any subscriber or to a specific user. Additionally, access control is
also afforded by the Zetron Model 30 Phone Patch.
See Zetron Phone Patch Manual (supplied with the phone patch) for specifications, operation,
installation, alignment, programming, and repair information.
