Digital Cable Modem M-101

Digital Cable Modem M-101 is intended for construction of a high-speed duplex digi­tal communication channel through two-wire and four-wire cable lines between the remote E1 interface devices.

Linear interface SHDSL meets ITU-T G.991.2.bis requirements and it is used for transmitting a linear code Trellis-Coded Pulse

Amplitude Modulation (TCPAM).
