General Acceptance Testing Parameters
The Microwave Zink providing the connectivity between the Mobile Communication Site and the City of Miami
Police Headquarters (CEB location) is designed for operation in the 5.8 GHz industrial, scientific, and medical
(ISM) band. Radio wave propagation in this band exhibits microwave characteristics that are ideally suited for
point-to-point, line -of -sight communications. Line -of -sight requires that the transmitting antenna and receiving
antenna are able to "see" each other, and that the line straight-line path between the two antennas is free of
obstructions such as buildings, trees and in longer paths, even the curvature of the earth.
With line -of sight microwave communications, optimum system performance requires that the transmitting and
receiving antennas are properly aligned. This ensures maximum received signal power at each receiver. Antenna
alignment must be achieved in both azimuth (along a horizontal plane) and elevation (along a vertical plane).
For the purposes of the Acceptance Test Procedures, the Mobile Communications System will be situated in a
mutually agreed location providing a good received signal strength indicator (RSSI) value. The console and
Microwave link testing will be conducted only in the field once the Embassy and dispatch consoles have been
programmed and interfaced to the new Mobile Communications System.

Console Features
Console Talkgroup Call
1. DESCRIPTION
Resource Windows are used to communicate with
talkgroups. Each talkgroup in the system will have
its own resource window.
A call from a subscriber unit to a console is indicated
on each dispatch operator position that has a resource
window associated with the channel the subscriber
unit is transmitting on.
When a subscriber keys on a talkgroup that the
console has selected, the subscriber's audio comes out
of the select speaker of the console. Audio on
talkgroups that the console has not selected is heard
on the unselected speaker.
If the resource has secure capability, a padlock button
appears in the resource window. If an incoming call
is uncoded and is received on a channel where the
transmit mode is set to coded, an unlocked padlock
appears in the call indicator area on the resource. If
an incoming call is coded and the transmit mode is
set to clear, a locked padlock appears in the call
indicator area.

Patch Operation
1. DESCRIPTION
The patch button allows the operator to group
available resources together so that they can
communicate with each other.
During a patch operation, only one voice channel will
be used, and all talkgroups involved in the patch will
have radio -to -radio communications.
A console initiated patch in the clear mode cannot be
upgraded to the coded mode.
A patch is best utilized when one needs to group
trunked communications with conventional, or when
it is necessary to have communications between
talkgroups that normally do not communicate with
one another.
A Patch has a limit of forty-eight (48)
trunked/conventional resources.
A secure patch requires that the DIU have a key in
location 3.

Multi -Select Operation
1. DESCRIPTION
Multi -Select allows the console operator to group a
number of channels/talkgroups together such that
when the general transmit bar is depressed, all of the
multi -selected channels/talkgroups will transmit at.
the same time with the same information.
Multi -Select is one-way communication call. If a
radio user responds to a multi -select call, the
talkgroup transmitted on will be the only one to hear
the transmission.
There is no super -group formed, so radio
communication is still at the single talkgroup level.
Multi -Select is utilized to send an APB to several
channels/talkgroups.
The number of trunked channels that are used for this
call can be one or the number of multi -selected
talkgroups depending on console setup.
Multi -Select has a limit of twenty (20)
trunking/conventional resources.
Secure Multi -Select requires that the DIU have a key
in location 3.

Console Priority
1. DESCRIPTION
Console operator positions have ultimate control of
transmitted audio on an assigned voice channel
resource. The console position possesses the
capability to take control of an assigned voice
channel for a talkgroup call so that the operator's
audio overrides any subscriber• audio. Console
priority is a feature that enables dispatchers to gain
immediate access to an assigned voice channel so
that a central point of audio control exists,
