VCL-DS3oP (DS3 / T3 Version)

TDM over IP / TDM over Packet

Product Overview

Aries Telecom and Trading Corp. FZE.  offers  'VCL-DS3oP', DS3 (T3) over Ethernet equipment provides  transmission of one, point-to-point, DS3 (T3)  link over an IP / Ethernet, MEF or MPLS network.

The 'VCL-DS3oP', DS3 (T3) over Ethernet equipment is powered by 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.

The 'VCL-DS3oP', DS3 (T3) over Ethernet 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 (Port Trunking),  Ethernet Route 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 network and equipment cost and generate additional revenue by offering different types of (Gigabit Ethernet, T1 and DS3) services over a single packet-switched infrastructure by the use of DS3oP equipment. As the networks migrate to an IP based infrastructure, the DS3 over Ethernet equipment becomes a valuable tool for enabling DS3 services for inter-connecting legacy DS3 equipment over Gigabit Ethernet optical fiber links, or over wired / wireless Ethernet/IP networks.

How the TDM over Packet, DS3 over Ethernet equipment works

The DS3 channel received from the customer side equipment on the DS3 interface of the DS3 over Ethernet equipment is converted by its DS3oP engine 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 the DS3 over Ethernet DS3oP equipment reconstructs the original data streams by removing the IP, MEF or MPLS headers and converts the Ethernet data packets back to DS3 frames using highly reliable and accurate clock recovery mechanism. The 'VCL-DS3oP', DS3 over Ethernet equipment uses standard SAToP, DS3 to packet and packet to DS3 conversion mechanism making it suitable for use over all types of Ethernet / IP or MPLS infrastructure.
