The XMP1 is a flexible 64kbit/s Access Multiplexer and Cross-
and SDH applications from 8kbit/s up to STM-4. It has both electrical and optical 2Mbit/s, 34Mbit/s and STM-1 it also has an STM-4 optical line interfaces accompanied by a wide range of 64kbit/s or Nx64kbit/s subscriber interfaces, that enables operators to build either PDH or SDH networks using just one highly integrated system.

XMP1 is a modular, flexible and highly integrated cross-connect system within a single network element on 8/64 kbit/s level for PDH part and VC-12, VC-3 and VC-4 level for the SDH unit. The transmission rates are from 8 kbit/s up to 34Mbit/s for PDH and STM-1 and STM-4. It is in each configuration always a fully non-blocking cross-connect configurable as a terminal or add/drop multiplexer that enables you to set up complex communication and data networks adapted to your bespoke requirements.

The capacity of the digital switching matrix is 16x2 Mbit/s: 480 timeslots using CAS-Signaling, or 496 using 31 channels. The cross-connect of each individual 64k signal inclusive associated signaling information (2kbit/s) is freely configurable. These signals can be terminated on service interfaces and combined with other 2Mbit/s signals (E1) for interworking with a transport network or as connection inside pure XMP1 networks. New enhancements mean that customers with an installed base of XMP1 can now migrate to SDH and SDSL services

Applications

The XMP1 has been designed as a cross-connect multiplexer for various applications. In its standard application it can be configured to provide point-to-point, leased-line services in corporate networks, offering a full range of voice, ISDN, data and LAN services.

The SDH and 64kbit/s cross-connection functionality is fully integrated to support a great variety of PDH 64kbit/s based network applications as well as the seamless integration into STM-1/STM-4 rings, stars and meshed networks.

Furthermore, the newest extension of XMP1 by integrated SDH perspectives of migration for the customer based on the installed network base of XMP1.
