IDM-TOP series of products are also called IP circuit emulator or adverse gateway. IDM-TOP16 supports 16 groups of E1 service base on TDM be extended to packet exchange network. Via the group network (Ethernet, IP network or MPLS network), the transmission of TDM service is very convenient. At the same time, the system assures the clock of the TDM and the jitter characteristics are superior to the ITU. Firstly, turn 16 E1/T1 circuit to IP groups, then transmit it to the Ethernet/IP network via 10/100base-T (or 100base-FX) layer.

The IDM-TOP equipments turn the TDM service to data packets which are based on the PSN network, the other side of the network executes adverse operation. It can be used on interface conversion, industry custom bandwidth rents, the TDM solution based on PON equipments in public network, Wireless equipments TDM solution, TDM circuit realization on industry Ethernet ring, IP private network consumers accessing improvement and the conversion of the E1 channel in the twisted-pair.

1. Features of 16E1 over IP converter
Archive the conversion of 16 groups of TDM services into packet exchange network;
Can transport on the complicated IP exchange network and so it can adapt some time delay while the transmission capability is good on the second layer of the Ethernet;
Supporting framed (all or part of it) and unframed E1 flow. The separate frames can be configured flexibly;
Qos management, low processing time delay; Assure the quality of TDM service;
