Purpose of TDM over Packet technology
Telecom companies and enterprise users can save significant network and equipment cost and generate additional revenue by offering different types of services over a single packet-switched infrastructure by the use of E1oP equipment. The E1oP equipment is also suitable for connecting to Ethernet / packet wireless equipment to achieve fast deployment of E1 services over wireless Ethernet networks. One particular application is to build E1 links with low cost Wireless LAN bridges, replacing expensive TDM / E1 microwave radios.
The 4 x E1 over Ethernet (VCL-E1oP) multiplexer may be used to provide legacy TDM services over Ethernet optical fiber, or wireless Ethernet/IP networks.
How the TDM over Packet (4 E1 Port FE Version) equipment works
The E1 data streams received on the E1 interfaces are converted by the E1oP engine of the E1oP equipment to Ethernet data packets (of a fixed size) and transported over the Ethernet network with UDP / IP, MEF or MPLS headers. At the receiving end the E1oP reconstructs the original data streams by removing the IP, MEF or MPLS headers and converts the Ethernet data packets back to E1 frames using highly reliable and accurate clock recovery mechanism. The 'VCL-E1oP' (4 E1 Port FE Version) offers the user a choice of standard, E1 to packet and packet to E1 conversion mechanisms that include SAToP and CESoPSN technologies.

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.
