VCL-T1oP (2 T1 Port FE Version)
TDM to IP / TDM to Packet
Orion Telecom Networks Inc. offers 'VCL-T1oP' T1 over Packet (2 T1 Port FE Version) TDM over IP equipment supports transmission of up to 2 x T1 links over IP / Ethernet, MEF or MPLS Pseudo-wire networks.
The 'VCL-T1oP' T1 over Packet (2 T1 Port FE Version) TDM over IP equipment, equipped with a powerful ARM-Cortex Processor which provides a highly reliable clock recovery mechanism for low jitter and wander control, even under variable network conditions.
2 x T1 Port T1oP (T1 over Packet) TDM over IP equipment is available with various Electrical (10/100BaseT) and Optical (100BaseFX) Ethernet port options which allow the users to implement 1+1 add-drop (Drop-Insert), Ethernet link redundancy (using Port Trunking / Port Bonding) and 802.1p based QoS mechanisms for network optimization.
The 'VCL-T1oP' T1 over Packet (2 T1 Port FE 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.

Few Key Features Explained
VLAN Based Priority (Classifying Services) - VLAN based Priority feature allows the user to assign priorities to different VLANs carrying various types of services / traffic according based on user categories and preferences. The user may assign highest priority to TDM (E1/E3) traffic and Ethernet services on a lower priority. User may also configure which TDM link should be given preference over the other TDM links when the uplink bandwidth falls below a particular threshold.
Flow Control in an Ethernet Packet Networks: (Regulating Traffic) - Flow Control feature allows the user to regulate Ethernet traffic flow to minimize packet loss due to data bursts.
Port / Customer based bandwidth allocation (Port Rate Limiting) - Port based Ingress Ethernet Rate Limiting allows the user to assign the bandwidth as per port / service requirements, in addition to provisioning traffic by using 802.1Q and 802.1p VLANs and packet priority.
