provide economical LTR forma
logic control of most any.800, 900, 450 or 220 MHz
repeater, the IDA Model RLC (Repeater Logic Controller) represents a significant price
breakthrough. Never before has LTR been so affordable.
When purchased with IDA's superior sounding interconnect, the RLC becomes an even greater
price/performance value. The microprocessor-controlled RLC was designed to function as the
controller of an SMR trunking repeater.
The RLC monitors the repeater channel for a mobile transmission. If a mobile begins
transmitting, the RLC decodes the subaudible data containing the mobile's ID, places the
information on the repeater data bus, and begins to send the handshake to the mobile. If
there is an ID validator on the system, and the mobile is invalid, the RLC will invalidate
the mobile using either Quick or normal invalidation.
If the ID is valid, the handshake will be completed, and the mobile will be able to use
the repeater. When the repeater is busy with a mobile transmission, the RLC sends
subaudible information to all the other mobiles assigned to the repeater, telling them
which repeater is to be used.
CROSSBUSY CIRCUITRY is a standard feature of the
The crossbusy feature allows LTR format trunking on "Non-Exclusive" channels.
Designed to protect against causing Co-Channel interference, the crossbusy feature of the
RLC will not allow LTR mobile radios to transmit or "step on" co-channel users
if activity is detected.
The LTR mobiles are trunked to an open channel if available. If an open channel is not
available, the trunking system is considered busy and the busy indication is sent to the
LTR mobile. In addition, this feature allows LTR trunking mobiles and conventional mobiles
to co-exist on the same repeater.
The RLC is merely installed along with the existing conventional panel. When a
conventional mobile is using the channel, the RLC will trunk the LTR mobile to another
available repeater. To provide maximum efficiency, when trunking "non-exclusive"
channels it is best to limit the home channel or channels to LTR only.
OPTIONAL: System wide validation and billing data
If constructing a new LTR � site is in your plans or
just adding more channels, you owe it to yourself to check out the RLC. Call the friendly
sales staff at IDA and learn how affordable "logic" can be.
