VCL-E3oP (E3 Version)

TDM over IP / TDM over Packet

Product Overview

Aries Telecom and Trading Corp. FZE. offers  'VCL-E3oP' (E3 over IP) equipment is used to transport a single E3 interface over an IP, MPLS or Ethernet network.

The 'VCL-E3oP' (E3 over IP) equipment, is equipped with a powerful PowerPC 400 MHz Processor which provides a highly reliable clock recovery mechanism for low jitter and wander control, even under variable network conditions.

'VCL-E3oP' is equipment provides 2 x GigE electrical ports along with 2 x Gigabit optical ports which allow the Users to implement 1+1 Ethernet link redundancy (Spanning Tree Protocol) and QoS by implementing Differentiated Services (DiffServ) and packet priority classification protocols for network optimization.

Purpose of TDM over Packet technology

Telecom companies and enterprise users can save significant network and equipment cost and generate additional revenue by offering different types of services over a single packet-switched infrastructure by the use of E3oP equipment. The E3oP equipment is also suitable for connecting to Ethernet / packet wireless equipment to achieve fast deployment of E3 services over wireless Ethernet networks. One particular application is to build E3 links with low cost Wireless LAN bridges, replacing expensive TDM / PDH microwave radios.

The 'VCL-E3oP' (E3 over IP) multiplexer may be used to provide legacy TDM services over Gigabit Ethernet optical fiber, or wireless Ethernet/IP networks.

How the  TDM over Packet (E3 Interface TDM over IP Version) equipment works

The E3 data stream received on the E3 interface is converted by the E3oP engine of the E3oP equipment to Ethernet data packets (of a fixed size) and transported over the Ethernet network with UDP / IP, MEF or MPLS headers. At the receiving end the E3oP reconstructs the original data streams by removing the IP, MEF or MPLS headers and converts the Ethernet data packets back to E3 frames using highly reliable and accurate clock recovery mechanism. The 'VCL-E3oP' (E3 over IP) equipment uses standard E3 to packet and packet to E3 conversion mechanism using the SAToP technology.
