The LT-4900 is for the "dispatch only" or "Interconnect" channels on any Logic Trunked Repeater (LTR®) System. The LT-4900 can be easily user configured for compatibility with either the EF Johnson or Uniden repeater bus protocols. The LT-4900 will operate flawlessly with other makes of controllers on the same system. The LT-4900 is fully self contained and includes every important Controller feature such as Logic Control Unit, Validator, Billing Data Generator, and System Manager. Many of the important LT-4900 standard features such as the front panel LCD display are simply unavailable in competing brands.

The interconnect supports End to End, E&M, and DID telephone systems.

Included with the unit is CSIBASE. CSIBASE Is a DOS based application for your PC that gives you full control and management of the LT-4900 controllers on each system and each site you operate.
