Industrial G.SHDSL.bis EFM/TDM Modem – E1/V.24/V.35/Ethernet

The Comet 164x & Comet 165x EFM/TDM series is industrial grade DSL modem which takes advantage of the latest G.SHDSL.bis standard, enabling the data to be transmitted  from Ethernet, E1, RS-232 and Nx64k Data interface with speed 5.7 / 11.4Mbps 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, RS-232 and/or Nx64k Data port and also with Ethernet traffic together.
