VCL Products > TDM over IP > VCL-E1oP (32E1 Port GE Version) - Technical Specifications
Our Gigabit Ethernet (GE) version products use a high-stability timing, ultra low noise OCXO for accurate timing and highly stable clock synchronization. This provides very stable clock synchronization and exceptional performance even under the most demanding network conditions.
VCL-E1oP (32E1 Port GE Version)
TDM over IP / TDM over Packet / TDM over MPLS
Technical Specification
'VCL-E1oP' E1 over Packet (32 E1 Port GE Version) TDM over IP equipment supports transmission of up to 32 x E1 links over IP/Ethernet, MEF, or MPLS pseudo-wire networks. The 'VCL-E1oP' E1 over Packet (32 E1 Port GE Version) TDM over IP equipment is equipped with a highly reliable clock recovery mechanism for low jitter and wander control, even under variable network conditions. 32 x E1 Port E1oP (E1 over Packet) equipment provides 4x Gigabit electrical Ethernet ports along with 4x Gigabit optical Ethernet ports, out of which the user may select and use any 4 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.
