M28946
G.shdsl Dual-Bearer Multi-Mode Transceiver
Overview
Description
The M28946, part of the M28976 chipset, includes two independent full-rate T1/E1 interfaces, capable of simultaneously carrying two separate pulse code modulation (PCM) data streams over a single twisted pair. Utilizing advanced 32-level pulse amplitude modulation (PAM), the M28946 operates at speeds up to 4640, or twice the normal G.shdsl rate, enabling operators to double their line utilization at distances of up to 7,000 feet or 2 KM. The M28946 offers all of the features provided by the M28945 multi-mode transceiver including multi-pair operation and guaranteed interoperability with legacy systems including HDSL2, SDSL and Mindspeed's AutoBaud™ software.
