XRT75R06 6-Channel DS3/E3 Line Interface Unit (LIU) with Jitter Attenuator with R³ Technology™

The XRT75R06 is a six-channel DS3/E3 Line Interface Unit (LIU) with Jitter Attenuator with R3 TechnologyTM. It incorporates an independent receiver for each channel, transmitter and jitter attenuator, and supports E3 (34.368.Mbps), DS3 (44.736Mbps) and STS-1 (51.84 Mbps) modes of operation. The device has a differential receiver, which provides a high noise interference margin capable of receiving data from cables of over 1,000 feet or up to 12dB of cable attenuation. It contains an onboard Pseudo Random Binary Sequence (PRBS) generator and detector with the ability to insert and detect single bit error. This function can be used for diagnostic purposes. The device meets jitter and wander specifications described in the T1.105.03b, and ETSI TBR-24, and is compliant with jitter transfer templates outlined in ITU G.751, G.752 and G.755. It also provides a serial microprocessor interface as well as hardware mode for configuration and control.
