RLC Stand Alone LTR� Logic

Designed to provide economical LTR � format 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 sub audible 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 sub audible information to all the other mobiles assigned to the repeater, telling them which repeater is to be used. 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.

RLC CAPABILITIES & FEATURES

	Quick invalidation which doesn't handshake with an invalid mobile, so that an invalid mobile cannot keep the repeater busy.
	Supports both EF Johnson RDB and Uniden RNDL bus.
	Second sync mode which acts as a backup to the primary sync unit on the repeater data bus.
	Capable of transmitting FCC system ID.
	Switchable polarity of sub-audible data and COR signals.
	Selectable hang time for loss of.COR and loss of mobile data.
	Time out timer for continuous transmission.
	Switchable enable/disable of the idle repeater message.
	Cross Busy Circuitry is a standard feature allowing the RLC to share the same repeater with a conventional tone panel. Converts your conventional channels to LTR trunking format at the same time allowing the channels to be used by existing conventional mobiles.
	Validation Option This option provides system-wide validation. Validation and invalidation of customer ID codes can be done over-the-air with DTMF tones, remotely via phone line and modem, or locally.n

LTI Logic Trunked Interconnect

The LTI (Logic Trunked Interconnect) module is designed to add high performance telephone interconnect capability to the IDA model RLC (Repeater Logic Controller). Incorporating all of the design innovations and engineering enhancements made possible by 15 years of building LTR � trunking equipment, the LTI is a price performance breakthrough in a small easy-to-install package. If you are constructing a new LTR site or adding new channels, the RLC & LTI combination makes good economical sense.

	Dynamic Loading The dynamic loading feature allows the system operator to prioritize system usage based on which customer and what type of call. The LTI recalculates system activity every 30 seconds and will automatically adjust any or all of the following. -Interconnect call length timers. The 4 separate call length timers are adjusted independently -Maximum total interconnect calls in progress -Enable/Disable low priority dispatch users -Enable/Disable high priority dispatch users
	Airtime Billing Data Collection Each LTI has a 128K buffer. The Master LTI can store any billing records received on the TLA bus. – Dispatch airtime data collection – Interconnect airtime data collection – 64K of dispatch billing data can be stored in the Master LTI – Condensed dispatch records by hour, by day, or by billing period – Interconnect airtime billing records that exceed the Master LTI’s storage capacity are sent to other LTI’s on the system. Each additional LTI has 128K of buffer.
