MDR Store & Forward Adapter

Overview

• Synchronous Terminal Adapter converting ISDN LAPD/X.25 to LAPB/X.25
• Supports Lucent 5ESS® Switch APCP protocol
• Interfaces 5ESS® Switch ISDN API to CAS
• Buffers up to 30,000 MDR records
• Integral ISDN BRI “U” interface

The Transactor – MDR Store and Forward Adapter provides a buffered interface between the ISDN Application Processor Interface (API) of a Lucent 5ESS Switch and an X.25-connected Call Accounting System (CAS).

The Transactor essentially acts as a Synchronous Terminal Adapter, converting ISDN LAPD/X.25 to RS-232 LAPB/X.25. However, both protocol interfaces are fully terminated in the Transactor up to and including the Lucent 5ESS Application Processor Communication Package (APCP) protocol. The MDR records are extracted from the APCP messages from the 5ESS and repackaged in Network APCP protocol over the X.25 port towards the CAS. Because the X.25 network is not always reliable, during outages the Transactor will store up to 30,000 records for forwarding when the network is operational again.

For Call Accounting Systems previously connected using a Terminal Adapter, the Transactor can be connected without modification to the CAS or the 5ESS, and immediately extend the buffering capacity of the 5ESS.
