Tempest Makes It Simple

Lucent WaveStar ADM 4/1 multiplexer
A synchronous access multiplexer that multiplexes standard PDH or SDH signals into one or two STM-1 or STM-4 signals

The WaveStar® ADM 4/1 system has as the main application to give access to an SDH network. It can work in both synchronous and asynchronous environments. Further, it contains an advanced pointer processing feature to eliminate phase shifts so it can be used for wireless base stations that need to be in perfect synchronization with the master station. The system can be used as a terminal multiplexer / dual terminal multiplexer (126 x 2 Mbit/s) or as an add/ drop multiplexer for up to 63 x 2 Mbit/s or a Hub Multiplexer for up to 5 STM-1 interfaces. It can be used in a large variety of network types such as rings, stars and strings. It has advanced protection mechanisms such as card protection, MSP, path protection and SNCP. Synchronization could come from various sources such as from 2 Mbit/s tributary, STM-1 aggregate incoming signal, STM-1 tributary incoming signal or an external 2 MHz clock.

The WaveStar ADM 4/1 consists of a shelf with 1 supervision slot and 6 flexible slots that can contain units with one or more of the following functionalities: 16 x 2 Mbit/s tributaries, 32 x 2 Mbit/s tributaries, 34 Mbit/s or 45 Mbit/s tributary, STM-1 optical or electrical line interface, STM-4 optical line interface, transfer for the add/ drop function. All boards have on-board power converters. In case of card protection, 2 Mbit/s switches are mounted on the connecting field of the shelf.
