VALIANTCOMMUNICATIONSVCL-E1oP (4E1 Port FE Version)4E1 over Packet / TDM over IPProduct OverviewValiant’s 'VCL-E1oP' E1 over Packet (4 E1 Port FE Version)TDM over IP equipment supports transmission of up to 4 x E1links over IP / Ethernet, MEF or MPLS networks.The 'VCL-E1oP' E1 over Packet (4 E1 Port FE Version) TDMover IP equipment, equipped with a powerful ARM-CortexProcessor which provides a highly reliable clock recoverymechanism for low jitter and wander control, even undervariable network conditions.4 x E1 Port E1oP (E1 over Packet) TDM over IP equipment isavailable with various Electrical (10/100BaseT) and Optical(100BaseFX) Ethernet port options which allow the users toimplement 1 1 add-drop (Drop-Insert), Ethernet linkredundancy (using Port Trunking / Port Bonding) and 802.1pbased QoS mechanisms for network optimization.The 'VCL-E1oP' E1 over Packet (4 E1 Port FE Version) TDMover IP equipment also optimizes on the network usage,such that the bandwidth used by the E1oP equipment on thepacket network is limited to the corresponding to the numberof E1 ports and the time-slots that are being transported overthe Ethernet / packet network.How the TDM over Packet (4 E1 Port FE Version) equipmentworksThe E1 data streams received on the E1 interfaces areconverted by the E1oP engine of the E1oP equipment toEthernet data packets (of a fixed size) and transported overthe Ethernet network with UDP / IP, MEF or MPLS headers.At the receiving end the E1oP reconstructs the original datastreams by removing the IP, MEF or MPLS headers andconverts the Ethernet data packets back to E1 frames usinghighly reliable and accurate clock recovery mechanism. The'VCL-E1oP' (4 E1 Port FE Version) offers the user a choice ofstandard, E1 to packet and packet to E1 conversionmechanisms that include SAToP and CESoPSNtechnologies.Hardware Highlights 19-Inch rack mountable 1U form factor (44mm) 1 1 Redundant Power Supplies, AC and DC, or AC plus DC.Redundant power supply inputs.Extended Temperature Range: (-200C to 600C)EMI / EMC ComplaintReal Time battery backed clock with life in excess of 10YearsPower over Ethernet (PoE) - OptionalPurpose of TDM over Packet technologyE1 Clock recovery and synchronization techniques:Telecom companies and enterprise users can savesignificant network and equipment cost and generateadditional revenue by offering different types of services overa single packet-switched infrastructure by the use of E1oPequipment. The E1oP equipment is also suitable forconnecting to Ethernet / packet wireless equipment toachieve fast deployment of E1 services over wirelessEthernet networks. One particular application is to build E1links with low cost Wireless LAN bridges, replacingexpensive TDM / E1 microwave radios.
