Smart multiplexer integrates ISDN, LAN and TDM access

In order to achieve optimum utilisation of Wide Area Network resources, Microtel has introduced the new E201 Multiplexer. It combines the benefits of a smart ISDN switch together with a time division multiplex (TDM) access device, allowing serial data and IP Ethernet traffic to be delivered simultaneously over a single E1 or even FE1 connection.

The new unit is equally suited to the needs of telecom operators who wish to deliver combined ISDN and data services over a single 2 Mbit/s connection, or for corporate clients deploying leased-line services over point-to-point multiservice connections.

The standard E201 unit is equipped with two 2 Mbit/s G.703 interfaces, one universal Nx64k interface and one Ethernet interface, allowing it to offer end-user connectivity for primary-rate ISDN (PRI), Nx64k serial data and IP Ethernet traffic for maximum flexibility of network applications.

The unit is fully compliant to the European ISDN standard (Q.931), and features full ISDN switching between the two G.703 interfaces to reduce network charges. It includes facilities for call filtering and ISDN number alterations (e.g. prefix dialling) for further network savings.
