1. DMux - 30 (MK-II)

When the PCM technology was developed as the semiconductor industry since early 1960's, today the channel bank digitized voice is the most effective solution for toll quality voice transport around the world.

By adoption of large scale ASIC chip set and the absorption of different PCM design experience by other manufacturers, AiSai designs the high compact and the most cost effective channel bank voice / data multiplexer - DMUX 30 (MK-II). The state of art integrated circuit design provides reliability and availability, and the modular design provides the highest flexibility and scalability. There have total 6 slots for the user interface module and trunk (mux) module.

The DMUX-30(MK-II) provides E1 mux card as well as fiber mux card that is used for fiber network direct access. The FO-4 fiber mux card also provides 4 addional E1 ports for further system expansion. Each interface module provides 6 circuits and DMUX-30 (MK-II) supports up to 30 voice or data channels that can be any kinds analogue voice or data transport. Service provider can depend on the demand to install the user interface modules that provide mixed voice and data services, which save the initial cost and also shorten the ROI period.

The system design is fully comply with the PCM multiplexing and international standards. such as G.703 / G.704. G.711 and G.823. The TDM bit-interleaved technology guaranties the low delay and the best voice quality. System supports different timing source, including master / slave clock and looped recovery clock mode. System up and running is just a minute of work.

The DMUX-30 (MK-II) provides the excellent voice quality and is the best timely solution for all telecom carriers and private enterprises. In combine with the E1 wireless or fiber optical network, the DMUX-30 (MK-II) can achieves the fastest voice / data deployment as the voice extender, point to point hotline or 64K leased data services, especially for the rural area and the remote office.
