 ISDN Lite Switch
 

Introduction. What is an ISDN Lite and what it can do

ISDN Lite is an adjunct processor/switch organized as a scalable set of Processing Modules (PMs). It resides on a PCI interface of a control workstation. The control workstation is an IBM RS/6000 communications server, or some other general-purpose computer equipped with a PCI external connector. ISDN Lite can be configured and deployed in cost-effective solutions for some of the most difficult ISDN-related problems faced by carriers today:

  • Provisioning ISDN BRI in non-ISDN Central Office areas
  • Serving ISDN customers located beyond the Carrier Service Area (CSA)
  • Relieving ISDN Central Office switch congestion.

ISDN Lite services and systems will comply with established standards and operational support system requirements:

  • Basic criteria will be in accordance with ISDN N1, N2 and N3
  • Standards conformance
  • Q.921
  • Q.931
  • Q.941
  • Switch/OSS interfaces
  • TR08
  • TR303
  • X.25 protocol
  • SS7 generation, recognition, and interoperation

These capabilities enable ISDN Lite to function as a full Network Element and interface with existing Operational Support Systems. As may be necessary, IBM or the customer may develop special features and interfaces.
