Product Overview

'Orion Telecom Networks Inc. offers VCL-T1oP' T1 over Packet (2 T1 Port IEEE-1588v2 Version) TDM over IP equipment supports transmission of up to 2 x T1 links over IP / Ethernet, MEF or MPLS networks and synchronization using IEEE-1588v2 protocol.

The 'VCL-T1oP' T1 over Packet (2 T1 Port IEEE-1588 Version) TDM over IP equipment with IEEE-1588 protocol engine which provides a highly reliable clock recovery mechanism for extremely low jitter and wander control, even under variable network conditions.

2 x T1 Port T1oP (T1 over Packet) TDM over IP equipment provides 4 x GigE electrical ports along with 4 x Gigabit optical ports (out of which the user may select and use any 4 ports) to implement 1+1 add-drop (Drop-Insert), 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.
