REDCOM SLICE® Radio Interface Module

REDCOM SLICE® Radio Interface Module
Connects REDCOM SLICE® and SLICE® 2100™ to military and commercial radios
Easy message-based setup
Allows back-to-back radio patches with VOX, COR & PTT
Security check for encrypted military radios
Suppresses repeater squelch tail noise burst
Three monitor speaker outputs
Supports multi-user dial-in monitoring via analog, digital & IP
Security check for encrypted radios
Interoperable with encrypted military radios, REDCOM’s Radio
Interface Module verifies that the radio is secure before the voice
transmission is enabled.
Radio users gain access
to REDCOM system features
Adjustable gain
The REDCOM Radio Interface Module can be installed into any
empty module bay in the REDCOM SLICE or SLICE 2100. This
module provides a simple and reliable connection between the
SLICE or SLICE 2100 and two-way radio systems. Radio users gain
all the same benefits of a REDCOM system normally available to
station users. The feature allows any phone in the REDCOM SLICE
or SLICE 2100 network to dial out to a remote radio, or allows a
radio to dial directly into the system and ring a phone, make an
outside call, or call another remote radio system.
REDCOM’s Radio Interface Module provides adjustable gain to
accommodate radio audio and long cable lengths, enabling
geographic distribution between the radio base unit and the
Multi-user dial-in monitoring
Several users can monitor radio traffic by dialing in via analog
telephone systems, digital (ISDN) phones, or IP phones. This
feature can also be password controlled for enhanced security.
Supports VOX, COR & PTT calling
The module contains two circuits and supports full two-way
calling with Push To Talk (PTT), Voice Operated Transmission (VOX),
DTMF, or Carrier Operated Relay (COR). Each circuit can interface
with an HF or UHF/VHF (DTMF) radio for simplex or duplex
operation. The Module allows direct, back-to-back radio patches
with both VOX and COR.
Effectively suppresses
repeater squelch
REDCOM technology removes the annoyance of repeater squelch
tail noise found in analog radios commonly in use with police, fire,
municipal and commercial/industrial communication networks.
• Transmission in each direction can be VOX controlled, with
built-in timing to facilitate transmit/receive transitions.
• Operating parameters can be changed in the field to accommodate specific radio system characteristics.
• Parameters are stored in non-volatile RAM for protection if the
board is removed or power is interrupted.
• Can optionally transmit a ring sound over the radio to the
remote user to notify of an incoming call.
• On-board microprocessor controls the 2-way VOX, call progress
monitoring, and timing operations without the use of specially
equipped phones.
• Auto answer is available on a port-by-port basis and can be set
to answer on ring number 1–255.
• PTT activation from REDCOM LCS or ISDN CommandSet™
• Call records are generated for radio usage.

REDCOM SLICE 2100 Radio Interoperability
SIP Trunks
with Radio Interface Module
Base Radio
• Front panel LED indications
• Standard interface compatible with
normal balanced/unbalanced remote
radio electrical characteristics
• Remote Supervision Release allows the
switch software to release the radio
circuit on detection of on-hook from
the phone network
• Variable audio delay to accommodate
scanners and secure preamble
Monitor Radio Audio
• 3 monitor speaker outputs for use
with amplified speakers and/or dial-up
Output Gain
• The output can be adjusted to any level
between 0.1 and 8 mV rms into a 150 Ω
load, or –16 to +9 dBm0 into 600 Ω load.
Supported in:
• SLICE® V4.0 or higher
• SLICE® 2100™ V4.0 or higher
compatible RADIOS:
Input Gain
• The Radio Interface Module may be
adjusted to provide a 0 dBm level (PCM)
to the switch when the radio receive
input is any level between 100 mV rms
and 2 V rms (+8.5 to –17 dBm0 at 600 Ω).
Radio Requirements
• Microphone Input: low impedance 150
Ω (nominal 0.1–8 mV rms), or 600 Ω
(100 mV to 2 V).
• Speaker Output: 50 mV to 3 V rms into
the Radio Interface’s 600 Ω input.
Below is a list of radios that have been
tested by REDCOM for compatibility with
the Radio Interface:
• SINCGARS (RT-15xx and RT-17xx series,
various manufacturers)
• Cobra MicroTalk
• Rockwell Collins AN/VRC-100
• Harris AN/PRC-150
• Harris AN/PRC-117F
• Harris RF5000
• Motorola MaxTrac 300
• Kenwood TK-805D
