At last! An affordable full featured LTR^® Trunking panel with combined interconnect and dispatch logic.

See our new LT-4200L data logger.

The LT-4900 is comprised of an LT-4200 LTR^® dispatch board and a Model 4000 interconnect board. Therefore an LT-4200 can be readily upgraded into a LT-4900 in the future.

Dispatch operation is identical to the LT-4200.

The interconnect capability of the LT-4900 leaves the competition in the dust. End to End (E/E), Direct Inward Dialing (DID) and Ear & Mouth (E&M) are all included standard. That's not all, you can have E/E and DID operational in the same unit! Since all formats are included, you will never be faced with expensive hardware and software products!
