TDM over IP Communication

TAINET’s Fiber Ethernet Network Terminal Unit (FNTU) 761 series allows the operator to provide Ethernet data traffic and TDM E1 services such as inter-office LAN connectivity, Internet access and secure virtual private networks (VPNs). This approach extends the service over fiber, facilitates the management of differentiated services to the customer premises while ensuring Service Level Agreement (SLA) enforcement.

IP switching networks have been replacing the traditional SDH/PDH ring network. However, E1 connection still exists in local areas and remote offices. The problem of the E1 time slot transmission is that it is not able to access the IP switching network directly and it will cause the E1 circuit working devices to stop or seek the PTN network for extending access. FNTU 761 series is using Pseudo-Wire Emulation Edge to Edge (PWE3) technology to access the Ethernet. Based on the CESoPSN and SAToP standards, the optical and electrical Ethernet interfaces can easily access each node in the IP network and provide the so-called TDM over IP feature. 

While the mobile operators are taking a full swing on the deployment of LTE wireless networks; the SDH system is slowly replaced by IP fiber accessed network systems.

In order to continue supporting the old network system via its E1 interface, Tainet FNTU 761 provides the perfect TDM over IP solution. With FNTU 761, 4 to 32 E1 links will be transited into IP exchange networks. No matter it’s fiber IP network or microwave connectivity, FNTU will be a good fit for the existing system.
