Compact [multiservisnyy] multiplexer of level STM-1, which makes it possible to transfer voice and data as far as one line SDH and intended for the assignment to the small and average enterprises of the services of IP- transport, commutation Of ethernet and TDM.

Metropolis® AM1 Of plus- multiplexer and the data-transmission system, ensures multiplexing the wide spectrum of signals beside the flows STM-4 or STM-1.

Metropolis® AMU - compact multiplexer of the access of level STM-1 or STM-4 (with the declared support of level STM-16) for the sake of the high density of ports making possible at the point of the operators of connection to allow reliable, highly productive and high-speed communication line services.

These are the intellectual multiplexer and transmission system with the high capacity, which can multiplex standard speeds PDH and SDH to the higher levels, up to 2,5 Gbit/s (STM-16).
