Product Overview

Orion Telecom Networks Inc. offers 'VCL-T1oP' T1 TDM over Packet (8 T1 Port GE Version) TDM over IP equipment supports transmission of up to 8 x T1 links over IP / Ethernet, MEF or MPLS Pseudo-wire networks.

The 'VCL-T1oP' T1 over Packet (8 T1 Port GE Version) TDM over IP equipment, equipped with a highly reliable clock recovery mechanism for low jitter and wander control, even under variable network conditions.

8 T1 Port T1oP equipment provides 2 x GigE electrical ports along with 2 x Gigabit optical ports which allow the Users 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.

The 'VCL-T1oP' T1 over Packet (8 T1 Port GE Version) TDM over IP equipment also optimizes on the network usage, such that the bandwidth used by the T1oP equipment on the packet network is limited to the corresponding to the number of T1 ports and the time-slots that are being transported over the Ethernet / packet network.
