Digital Cable Modem Ethernet M-1201

Digital Cable Modem Ethernet M-1201

Modem is designed to construct a high­speed duplex digital link between remote de­vices with Ethernet-interface. Modem includes SHDSL-port, 4 Ethernet 10BASE-T/100Base- TX ports and a port with RS-232-interface.

Linear interface SHDSL complies with ITU- T G.991.2.bis recommendations and is used for transmitting TCPAM coding sets. Modem can mul­tiplex two SHDSL channels in one logical channel (four-wire mode) to increase ranging at the cost of decrease in speed on the channel without de­crease of total speed.

Provides connection of analog telephone in MB for organization of communication. Power supply of remote SHDSL regenerators.

Controlling from the front panel (keyboard + display with menu system) from PC through RS-332 or Ethernet using telnet.
