G.SHDSL.bis EFM / TDM Line Card Ethernet Access Device Networking Accessories Network Communication Solutions Selangor, Malaysia, Kuala Lumpur (KL), Petaling Jaya (PJ) Supplier, Master Distributors, Supply, Supplies | ALTAAS Topologies Sdn Bhd

The G.SHDSL.bis EFM/TDM line card series which takes advantage of the latest G.SHDSL.bis standard, is a mini-terminal enabling the transport of traffic from Ethernet and E1 interface with speed 5.7M/11.4M over EFM bonded 2/4 wires G.SHDSL.bis link.

The G.SHDSL.bis EFM/TDM line card supports high-speed dedicated symmetrical data transmission and utilizes DSL bandwidth. The automatic line rate can be up to 5.7Mbps over 2-wire copper line. To reduce operation/management burden, G.SHDSL.bis EFM/TDM line card within iEAC-16 can control and monitor remote unit via Embedded Operation Channel (EOC) by following ITU-T G.991.2.
