Product Information

Lucent’s Expandable Switching System (EXS – previously Excel) is a host-controlled, distributed, programmable switching architecture. Lucent EXS provides a modular, highly-integrated, single logical and scalable switch environment, supporting over 30,000 non-blocking ports.

The Lucent EXS environment lets application developers implement applications cost-effectively across a wide range of port configurations with the assurance of seamless, incremental and economical growth as needed. Modular, common platform components further project system investments.

Lucent EXS Architecture

Lucent EXS uses a client/server architecture where the link between the switch and the host is based on TCP/IP over Ethernet. A single host can manage all switching nodes in a Lucent EXS system; multiple hosts are also supported. EXNET serves as the backbone for EXS. This dual counter-rotating fiber ring technology utilizes 1.2 Gbps, multimode optics.

EXNET Controller and I/O. Each EXS module is equipped with an EXNET card set: an EXNET I/O and an EXNET Controller. The EXNET Controller’s CPU kernel consists of the MC68040/360 in companion mode for high performance.

The controller functions as a switch matrix in Lucent’s Selective Space Switching architecture to provide a seamless connection between the available timeslots on the EXNET and the timeslots on each node. The EXNET I/O provides the physical connection to the EXNET fiber ring. EXNET can integrate external service resources such as voice processing. Providing them access to a centralized environment maximizes switch efficiency and reduces resource contention.

Lucent Excel/EXS Features:

  • Open programmable distributed environment.
  • Non-blocking architecture across all nodes
  • Integrates individual platforms into single logical switch
  • Seamless growth and linear scalability
  • Ring, node and card-level redundancy
  • Cost effective access to voice resources.

Cantata would later market the Excel switching platform and it is now Dialogic the company that currently commercialises the EXS system.

If you require any spare part, complete system and even software for the Excel switches, please do not hesitate to contact Carritech.
