SDH - the technology of the synchronous digital hierarchy of the transmission of data - the solution for all levels.

     The family of single-board SDH of the multiplexers Of metropolis® AMS and Metropolis® Of aM1-Plus from Lucent Of technologies significantly enlarges the possibilities of designing of economical transport networks and networks of access.

     The multiplexers, which do not in practice have analogs on the contemporary telecommunication market, make it possible to solve many communication line tasks considerably cheaper and it is more effective, the utilized as far as previously PDH systems. The wide collection of the interfaces (E1, E3, STM-1, X.21, Ethernet 10/100 Base- T) given to user considerably enlarges their field of application. This equipment easily is established before the wall and street cabinets, before the counters, before any accomodations of operators and enterprises of connection.

     With the aid of the family of the multiplexers Of metropolis® is possible the creation of the urban and local transport networks of level STM-1/STM-4, of extensions of digital flows from the transport main or the equipment of commutation; before the mobile connection for organizing the transport infrastructure of network.

     For the corporate customers - this is the inexpensive solution “fiber for the business” (access to the networks of the operators of connection, connection LAN-LAN, [UATS]/[ATS] flows).

     The interfaces Of [e]1 can be programmed with the renewal function of synchronization. This makes it possible to forego the additional hardware with the synchronization of other equipment from the channels 2 Mbit/s. The interfaces Of ethernet can be used for creating their own corporate network or for the assignment to the customers of the services of virtual local computational networks.

     Before the networks, built on the systems of mini-SDH, as the system of technical operation and maintenance is completely effective the use of a program packet ITM-CIT on the base usual PK with OS Windows. This system realizes practically all functions of the more complex systems for net control.

     Company “[NTTS] energy” achieves delivery of equipment based on the storage before Moscow and under the order, allows services on its installation, start- adjustment, down guarantee and post to after-sales service.
