Multichannel LIUs have integrated jitter attenuator and SONET desynchroniser

5 November 2003 Telecoms, Datacoms, Wireless, IoT

Exar has announced the industry's first DS3/E3/STS-1 LIUs with an integrated jitter attenuator and SONET desynchroniser. Extending last year's original R3 Technology (Reconfigurable, Relayless Redundancy) offering in its T1/E1/J1 products, Exar has now made this capability available in its DS3/E3/STS-1 devices. Applications include access equipment, digital cross-connect systems, routers, and digital subscriber line access multiplexer (DSLAMs), or any networking equipment located between the high-speed core and the lower-speed access network.

Exar has released five new devices: Two address desynchronisation requirements for mapping/demapping between SONET/SDH (synchronous) and DS3/E3 (asynchronous) networking environments: XRT75R03D (three-channel), and XRT75R12D (12-channel). Complementing these devices are the XRT75R03 (three-channel) and XRT75R12 (12-channel) with on-board jitter attenuator for applications where this capability is needed. Exar also offers a pin compatible device without the jitter attenuator, the XRT73R12.
