2.4. E1 Multiplexer

Many Service Providers have already adapted SDH as the

backbone of their fiber networks, and are providing E1

transmission interfaces via SDH ADM. Each subscriber has

different bandwidth and interface requirements, so an E1

bandwidth is usually segmented to fulfill different requirements.

Because several subscribers are sharing an E1 bandwidth, an E1

multiplexer will need to be installed at each client end.

MSAP2000 has integrated SDH ADM and E1 Multiplexer onto a

single shelf, which not only conserves space, but will also

standardize network management, and reduce hardware

investment costs. Moreover, MSAP2000 can also function as a

traditional E1 Multiplexer, to provide 2W/41 E&M, ISDN BRI,

Nx64 Kbps, and Fractional E1 services together with the Service

Provider’s existing SDH optic fiber facilities.
