Phone Patch Level Settings
The input and output levels should be adjusted per the phone patch’s instructions. The following
summary gives a brief overview of the high level characteristics and phone patch settings for
configuration with the SLR 8000 Base Station/Repeater.
summary gives a brief overview of the high level characteristics and phone patch settings for
configuration with the SLR 8000 Base Station/Repeater.
Disc
The Receiver audio yields 330 mV rms into 50 kΩ with an RF input signal deviating at 60% RSD.
With the phone patch's own loading impedance, the "Disc" signal delivered to the phone patch is at a
high enough drive level to leave jumper JP1 in the factory default position (position A).

Tx Audio
The transmitter yields 60% RSD with 80 mV rms into the Tx Audio port.
The "Tx Aud" signal delivered by the phone patch is at a high enough drive level to leave jumper JP3 in
the factory default position (position B).
the factory default position (position B).
CTCSS/ DCS DECODE INPUT/ COR
Set the jumpers on the phone patch as follows:
• Set jumper JP6 to position A, to match the base station/receiver's active low indication of a PL/DPL
detect.
• Set jumper JP7 to position B, to external squelch indication.
• Set jumper JP8 to position C, to match the base station/repeater's active low indication of a COR
detect.

Tone Remote Adapter
When a dispatch console or deskset sends out signals to a remote repeater, it does so over a Wireline.
Two types of signals are sent:
• Audio signal
• Command signals (function tones) that are used to perform the remote control functions.
