More details

TDM over IP toip ethernet to E1:TOIP-4


TDM over IP, 4E1s, 2 User Data Ports

Brief Introduction
As a cost effective solution for the traditional telecom services migrate to the IP packet networking technology, TOIP-4 adopts the innovative TDM over IP
technology, it transports the legacy E1 data through the existing Ethernet or IP network.
TOIP-4 is the new generation of the TDM over IP equipment with IP circuit emulation that supports transportation of four E1 and two local Ethernet ports over
Ethernet or IP network. The uplink ports and user data ports are IEEE 802.3 compliant, 10/100BaseT auto-sensed Ethernet port.
The state-of-the-art design provides the highest availability with the accurate timing signal and data bit stream reconstruction. Predefined system parameter
profiles that according to different application requirement; ultimately simplify the installation process and saving the maintenance cost.
Telecom and Enterprise users can save a lot of access and equipment costs and generates new revenue by offering different types of service over existing
Ethernet networks. It is also suitable for connecting to the wireless equipment to achieve fast deployment of E1 services. One particular application is to build E1 links with low cost Wireless LAN bridges, replacing much more costly microwave radios. Operators can use TOIP-4E1 to provide legacy TDM services over wired or wireless packet network.
1.        User-friendly Web server supported for easy setup and maintenance
2.        Support SNMP V1 and V2 network management
3.        Point to point and point to multipoint supported
4.        Four E1 Ports supported
5.        Uplink ports 1+1 backup supported
6.        Stable E1 clock recovery, low jitter and wander
7.        Low processing delay for E1 channels, high bandwidth usage efficiency
8.        Resist to packet loss, with PCM frame synchronization protection
9.        User definable encapsulation packet size for different application
10.    Support Ethernet encapsulation and UDP/IP protocol encapsulation.
11.    Support VLAN settings for E1 service and in band VLAN management.
12.    Enough jitter buffer to resist packet delay variation (PDV)
13.    Local Ethernet port throughput limiting, assuring E1 QoS
14.    Local and remote E1 LOS and AIS and packet loss indication for trouble- shooting and maintenance
15.    Support cascade concatenate for more than 4 E1 ports
