Product List E1 TDM Over IP
Product Summary

Tekway's TOIP TDM pseudowire gateway is customer located equipment (CLE), extending TDM-based services over IP, Ethernet and MPLS networks. Using TDM pseudowire technology, it delivers 1~4ch. E1 and 16~30FXS/FXO services over packet transport, in addition to enabling transparent LAN bridging.

The TOIP TDM pseudowire gateway supports carriers in their migration to next generation networks, by allowing them to continue generating revenues from their ongoing legacy services over PSNs.

The TOIP is designed to meet the requirements of small customer sites. It reduces operating expenses by delivering virtually all TDM, data and LAN services over IP/Ethernet/MPLS networks, while ensuring strict priority to the TDMoIP traffic over the network link. End users continue to receive all familiar services, while carriers and service providers maintain revenues from legacy services. The compact size, ease of installation and support for multiple legacy and next generation Ethernet and IP-based services, make it ideal for small and medium-sized enterprises (SMEs).
