AN-TDM-IP-2E1/A is used to setup 2 transparent E1’s channel over LAN or IP networks
The AN-TDM-IP-2E1/A has many optional parameters, which can be modified by the user to suite different application requirements. Please read this manual carefully before installing the product.
It is well known that the E1 signal comes from PCM technology which is TDM in nature. It transmits information in a constant bit rate of E1_2048kbit/s, TDM technology occupies fixed transmission bandwidth, with QoS features suitable for real-time applications such as voice and video. The QoS features include short and stable transmission delay, low jitter and wander, etc.
The most widely used application of AN-TDM-IP-2E1/A is to set up point to point wireless E1 links using low cost wireless LAN bridges. AN-TDM-IP-2E1/A can work with most LAN bridges on the market.
Until recently, voice and data were, and still are to a large extent, transported over two separate networks. But the requirement for both types of information to be carried over a unified network is growing rapid. Packets over SONET/SDH techniques to integrate date into the TDM network have been around for many years. But for voice over packet based data networks, most of the efforts are spent on creating special equipment that packets voice or video signals, such as VoIP techniques.
The AN-TDM-IP-2E1/A can be used to emulate transparent E1 channels over an Ethernet with adequate QoS, so that most of the existing E1 based applications can be readily setup over Ethernet LANs and WANs. One particular suited application is to build E1 links with low cost wireless LAN bridges, replacing much more costly microwave radios.
Both Web Server and SNMP management are supported through anyone of two Ethernet ports of AN-TDM-IP. The management has four sections: Status, Line Test, Configuration and System.
