Unit Description.
The DRC-32 desk-top controller from A.W. CommunicationSystems Limited
embodies the very latest hardware and software technology, thus maximising
functionality and reducing physicalsize of a radio control system operators unit to
that of a desk-top telephone unit.
Users of the DRC-32 can pre-select up to seven DS-32 channels for their individual
use. The operator can then select any one of the seen channels to transmit out on. A
monitor facility is provided to monitor the pre-selected channels without the transmit
function.
Only when a channel is selected will a transmission take place on that channel. Where
multiple operators have a channel in their pre-select groups, each operator can
monitor the outgoing audio from the other operators thus providing a fully informed
system.
The following is a brief description of the facilities available at your fingertips, all of
which are designed to enhance the radio facilities and ease the operator burden.
Please Note
The DRC-32 at your desktop will have been configured by your system supplier and
as such, may or may not have some of the features described herein enabled for your
use. Your supplier will help with any questions you may have regarding correct
operation and configuration.
Multiple Audio Paths.
The DRC1 will support operation using the built in loudspeaker and microphone, the
handset, which forms part of the unit, a plug in operator headset, and interconnection
with the telephone system. The DRC-1 also provides an audio input/output for use
with recording devices.
Individual Calling
Individual calling is the ability to call an individual mobile or portable radio terminal
using a uniquely allocated number. Having called the mobile resource, your
conversation with that mobile will not be overheard by the remainder of the fleet.
In an Individual calling system, a mobile wishing to communicate with a control room
operative makes a call using the unique number and the DRC-32 will either display
the call, or place it into a special queue to await operator call back.
It is also possible for the operator to call Groups of mobiles in order to make a
broadcast announcement or request.

Status Information
Status information forms part of the selective calling system. The status of a mobile is
indicated by appending one or more numbers to the mobile’s call-sign. In a similar
way, a control room operative can send a status code to a mobile to command a
required readiness state.
Alpha Tags
Alpha tags are text names, which can be allocated to individual identities, status
codes, and channels. These tags are intended to make the system readily
understandable by translating the numbers used within the system into text. By way of
example the incoming code 12349 can be tagged to display “Dog Van 3 Meal Break”
Headset Working
In busy control rooms it may be desirable to achieve quiet operation of the radio
system, and this can be achieved by plugging in an operator headset and microphone
combination. Once the operator is using the headset, then operation of the keypad
Transmit key will cause the operator’s voice to be transmitted. In receive mode, the
operator can choose to use the internal loudspeaker, or turn the loudspeaker off by
pressing the [LS] key.
Common Headset Working
If the operator is equipped with a headset, then the DRC-32 can also be
interconnected to the telephone system. This interconnection will have been
undertaken by your system supplier. By interconnecting the DRC-32 to the telephone
system, the operator can use the same headset to make and receive telephone and
radio calls. It is also possible to connect a mobile radio conversation directly to the
telephone system –see teleconnect.
Menu System
The menu system provides the operator access to many of the system facilities. The
menu is accessed by pressing the menu key and then using the up and down scroll
keys to move through the menu options. These are described in greater detail later.
Talk Through
Talk through is the term used for a facility which permits one mobile to speak with
another. It would be normal practise for the mobile requiring the talk through facility
to ask control to enable the facility. The DRC-32 can command talk through in several
-Page 6 –

ways which will depend upon what type of base station your service uses. This facility
is not available on TETRA channels.
Talk Through [TT] Key
The talk through key will enable the talk-through facility as described above. The key
will have been configured by your system supplier and there is no need here to
describe how it functions.
Facilities.
The [FAC]ilities key which can be found on the lower left hand side of the keypad
will have been programmed to control base station facilities. These facilities may be
unique to your service and as such is not possible for us to describe them here. By
way of example, your base stations may consist of a main equipment set, and a
standby equipment set. The standby set can be commanded to take over in the event
of equipment failure by operating the facilities key. When used with a TETRA
channel the Facility key selects either simplex or duplex calls.
Handset
In any mode of operation, picking up the handset will cause the DRC-1 to recognise
and use the handset microphone and ear-piece. For example, a control room
supervisor can pick up the handset and immediately communicate with a mobile
resource the operator is connected with.

Unit Connections.
The DRC-32 at your desk-top will have been installed and configured by your system
supplier. The connection information given below is offered as an aid to recognition
should any of the facilities become disconnected.

Menu System
The operation of the DRC-32 falls into two main categories being:-
1, Accessing and setting embedded facilities such as volume levels and alpha tags.
These would normally be set once and used many times.
2, using the frequently used facilities such as making and receiving calls from
terminals and from the telephone system.
Access to the items in category one is achieved through the menu system. The menu
system is termed a “nested” menu because once the upper menu has been accessed;
there are multiple choices which can be scrolled through using the scroll up and scroll
down keys.
The menu key itself acts as a select key and indicates to the system what choice the
operator is making from the options listed on the screen. The [CLEAR] keyacts as a
back-step key and its operation takes the operator one step backwards in the selection
process.
