2 Wire DID 4RU Plug-in Card
PRODUCT DESCRIPTION

The Fiber Optic Link 2-wire DID (Direct Inward Dialing) system provides a fiber optic transmission of a Telco DID TRUNK line to a PBX (loop start) over two optical fibers.

The copper signal is converted to optical, transmitted over fiber optic cable, and converted back into the original copper signal. This allows for network extension over long distances, and provides electrical isolation between both ends of the network.

The 2-wire DID system transmits signals in the voice-frequency or audio range (300Hz-3.4KHz) while providing reverse battery signaling to communicate call status. The 2 Wire DID system is compatible with any RLH 4RU card housing or shelf, is temperature hardened for tough environmental conditions where 24/7/365 operation and rugged reliability is important, and is covered by our Exclusive Unconditional Lifetime Warranty.

This card is designed to be installed into a 4RU card housing. See housings Here.
