Product Information

The Lucent 5ESS Class 5 Switch manufactured by Lucent Technologies is one of the most popular in the world servicing at one point in time approximately half of all U.S. telephone lines. The Lucent 5ESS was most recently marketed under the Alcatel-Lucent brand.

The VCDX (Very Compact Digital eXchange) was marketed to small telephone companies and was used in some instances as a large PBX. It consisted of a single Switching Module, had no Communications Module, and used a Sun Microsystems workstation as its Administrative Module.

Lucent 5ESS has three main types of modules:

  • Switching Module (SM) – Each SM handles several hundred to few thousand telephone lines or several hundred trunks or mixture thereof where each of them has its own processors, also called Module Controllers, which perform most call handling processes, using their own memory boards.
  • Administrative Module (AM) – AM is a dual processor mini main frame computer of the AT&T 3B series, running UNIX-RTR. AM contains the hard drives and tape drives used to load and backup the central and peripheral processor software and translations.
  • Communication Module (CM) – The Communications Modules form the central time switch of the exchange. 5ESS runs on a Time-Space-Time (TST) topology in which the Time-Slot-Interchangers (TSI) in the Switching Modules (SM) assign each phone call to a time slot for routing through the CM.
