G.SHDSL.bis EFM/TDM Modem – E1 V.35 Fast Ethernet

The Comet 163xF EFM/TDM series is DSL modem which takes advantage of the latest G.SHDSL.bis standard, enabling the data to be transmitted from Ethernet, E1 and Nx64k Data interface with speed 5.7M/11.4M over EFM bonded 2/4 wires G.SHDSL.bis link.

It supports up to 15 Mbps per pair of G.SHDSL.bis symmetrical data transmission under extension mode. Along with time-slot assignment feature, Comet 1632F/1634F series provide multiple user interfaces for TDM traffic including E1 and/or Nx64k Data port and also with Ethernet traffic together.
