QX3440-TDMoE Interface Card

QX3440-TDMoE Interface CardThe TDMoE plug-in card is designed for use within the QX3440, HX9500 & HX9550 multiplexers. The TDMoE card is used to transport TDM traffic over IP network, in addition to Ethernet traffic. As the communications network migrates from TDM to IP, the TDMoE card provides a flexible and cost effective choice for the transport of legacy TDM signals.

The TDMoE interface card has a 4 E1 back plane card or 4 x 31 TS. All E1 and TS can be
encapsulated  in  maximum 64 Pseudowires (PW) or Bundled to 64 directions. Each Bundle includes from 1 to 31 timeslots and also allows CAS signalization

There are 4 Ethernet ports on the face of the TDMoE interface cards which allow the unit to act as mini switch:

  • 2 x WAN ports Combo 10/100/1000BaseT and 1000SX/LX/ZX SFP
  • 2 x LAN ports 10/100/1000BaseT
