DESCRIPTION


The MD-400-E1T1 transports a T1 or E1 interface for voice and data service over longer distances than standard T1 DSX interfaces.

The MD-400-E1T1 embeds the latest G.SHDSL technologies that are approved by the ITU-T, ETSI and ANSI bodies for transporting E1/T1 services over copper pairs. SHDSL spectrum density is compatible with other voice and ADSL services when sharing the same multiple pair cables.

The MD-400-E1T1 operates on either one or two copper pairs to provide longer reach. Distances can also be raised up in inserting SHDL repeaters in the copper line.

The MD-400-E1T1 transports E1 or T1 interface, but also it performs Nx 64 kbps adaptive rate to provide to best throughput / distance ratio when transporting fractional E1 or T1 as the SHDSL reach increases for lower rates. The MD-400-E1T1 offers high performances in most line conditions and ensures stable transmission quality thanks to a user defined Signal to Noise Margin.

The terminal interface of the MD400E1T1 can be set as E1 or T1, full or in fractional mode with or without CRC. N fractional mode, the first extracted timeslot can be defined. The receiver sensitivity can be set for long or short haul.

The MD-400-E1T1 is easy to integrate in any application thanks to a choice of power supply options. It can be powered from a mains adapter or from a 48 Vdc battery.

The MD-400-E1T1 comes in a compact enclosure with DIN rail and wall mounting capabilities.

The MD-400-E1T1 comes with both a CO and CPE factory configurations that makes it a ready to run solution for clear channel operations. All parameters can be user defined through an intuitive menu interface. The MD-400-E1T1 can also be remotely controlled through the EOC channel as defined in the G.991.2 standard.

The MD-400-E1T1 does not support unchannelized (clear channel) T1.
