MTR3000 Third Party Controllers: Tone Remote Adapter E-13
Figure E-12 CPS Configuration for L3276 Tone Remote Adapter
E.4.5 Tone Remote Adapter settings
The input and output levels should be adjusted per the Tone Remote Adapter’s instructions. The
summary below gives a brief overview of the high level characteristics and typical Tone Remote
Adapter settings for configuration with the MTR3000 Base Station/Repeater.
E.4.5.1 Radio Rx
The MTR3000 Base Station/Repeater’s Receiver audio will yield 330mV rms into 50 kΩ with an RF
input signal deviating at 60% RSD. With the Remote Tone Adapter’s own loading impedance, the
“Radio Rx” signal delivered to the phone patch is at a high enough drive level to leave jumper S10 in
the factory default position (position is “out”).
E.4.5.2 Radio Tx
The MTR3000 Base Station/Repeater’s transmitter will yield 60% RSD with 80mV rms into the Tx
Audio port. The “Radio Tx” signal delivered by the Remote Tone Adapter is at a high enough drive
level to leave jumper S9 in the factory default position (position A).
Note
The above configuration is considered typical. The L3276 Remote Tone Adapter provides
alternate configurations that are supported by MTR3000 Base Station/Repeater as well.
Refer to the L3276 Remote Tone Adapter Manual for additional details.
