Release Notes for Cisco IPICS Release 2.1(1)
OL-12993-01
Introduction
Overview
The Cisco IPICS solution provides a cost-effective and highly-efficient
IP standards-based solution to enable voice interoperability among disparate
systems. By interconnecting voice channels, talk groups, and virtual talk groups
(VTGs), Cisco IPICS bridges communications from radio networks to the
Cisco IPICS Push-to-Talk Management Center (PMC) PC application and
supported models of Cisco Unified IP Phones.

Cisco IPICS release 2.1(1) includes enhancements to provide support for Tone
Remote Control (TRC) functionality. Tone Remote Control (also known as Tone
Control) refers to the use of a sequence of audible tones (inband tone sequences)
to control a radio that is connected to a Land Mobile Radio (LMR) gateway
(typically a base station). This control can be used, for example, to tune the radio
to a different frequency (change the channel).

Be aware that the version of Cisco IOS software that is required to support the
tone remote control functionality may not be available when Cisco IPICS release
2.1(1) becomes available. For updated availability information, refer to the

In this release, Cisco IPICS provides support for tone-controlled radios by
enabling the definition of radio channels in the Cisco IPICS server configuration
and implementing a 36-channel radio console skin in the PMC.

and implementing a 36-channel radio console skin in the PMC.
Each radio channel that you define in the server represents a physical radio that
can be configured with one or more operational tones, including high level guard
tones (HLGT), function tones (such as channel select and channel scan), and low
level guard tones (LLGT). The high level guard tone is usually the first tone in a
preamble, or the sequence of tones that precedes a transmission. The high level
guard tone is set at high volume to alert the radio that a function tone will follow.
The function tone follows the high level guard tone and causes the radio to
perform a specific function, such as selecting a new transmit frequency. The low
level guard tone is used as a hold tone or keying tone.

This radio-specific enhancement enables the PMC to send RFC 2198 and
RFC 2833 packets to control tone sequences on a per-channel basis. RFC 2833
dual-tone multifrequency (DTMF) is supported for the generation of DTMF
signals when these signals have been previously configured in the server via the
