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.
