TD-TDMOIP-20 Series

Product Overview

The TD-TDMOIP-20 series TDMOIP is based on self-developed with independent intellectual property rights of Techroutes Network (P) Ltd. TD-TDMOIP-20 series TDMOIP is based on the IETF of PWE3 SAToP / CESoPSN agreement standard. The equipment allows up to 16 El TDM data streams in L2TPv3/IPv4, UDP/IPv4, L2TPv3 /IPv6, UDP/IPv6, MPLS (MFA-8) and METRO Ethernet (MEF-8) transmitted crystal in the network.

TD-TDMOIP-20 Series CESoPSN can ensure that the circuit simulation communication priority, the jitter and wander in line with the G.823/G.824, G.8261, and TDM specification. Built-in slot allocation circuit TSA, any time slots per El port group can be reorganized .Have the Processing capacity of Channel Associated Signaling. Provide network management which based on the WEB, SNMP-band, and the network management information comprehensive. CESoPSN has a high transmission efficiency, low propagation delay, clock recovery and high accuracy characteristics can be widely used, including the vast majority of backhaul and other applications.

TD-TDMOIP-20 series provide Ethernet optical port and Ethernet electrical ports both in the Ethernet side of the device, while 1/2/4/8/16 El interface at the WAN side.
