E3 over IP / E3 over Ethernet , TDM over IP / TDM over Packet / TDM over Ethernet
Technical Specification

Product Overview

Valiant’s 'VCL-E3oP', E3 over IP / Ethernet equipment provides transmission of one, point-to-point, E3 link over an IP / Ethernet, MEF or MPLS Pseudo-wire networks. The E3oP is compatible with AES/DES Encryption Data standards.

The 'VCL-E3oP’, E3 over IP / 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-E3oP', E3 over IP / 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 (Rapid Spanning Tree Protocol and Ethernet Port Trunking) and QoS by implementing 802.1Q based VLAN, Differentiated Services (Diffserv / DSCP), Port based Priority and 802.1p packet priority classification protocols for network optimization.
