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, facilitating management of differentiated services up 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 are still existing in local areas and remote offices. The problem of the E1 time slot tansmission, it is not able to directly access the IP switching network and cause the E1 circuit working devices to stop or seek the PTN network for extenedng access.
TAINET TDM over IP (FNTU 761) series use Pseudo-Wire Emulation Edge to Edge (PWE3) pseudowire emulation technology to access and use in Ethernet. Based on the CESoPSN and SAToP standards, with optical and electrical Ethernet interfaces to easily access each node in the IP network and reache the so-called TDM over IP feature.
TAINET TDM over IP (FNTU 761) device can easily switch the E1 curcuit from 2G/3G base station to an IP packet switching network. The traditional E1 can also be used to switch to the IP network through FNTU 761, which facilitates connection tasks with the central database and the voice center.
