2.11.2 Switching Module Software
The switching module software provides all call processing and the necessary control
software to allow the switching module to communicate and pass data to and from the
AW.
2.12 Features
The DRM supports most of the features (for example, ISDN, Centrex) of the 5ESS
switch.
2.12.1 Signaling System 7 (SS7)
Signaling is provided by the Packet Switching Unit (PSU). For detailed information on
SS7, see 235-200-1165ESS Switch Signaling Gateway Common Channel Signaling
Document.
2.12.2 Session Initiation Protocol (SIP)
Session Initiation Protocol (SIP) - also supported on the PSU, for details see
235-200-1185ESSSwich Session Initiation Protocol - OAM Manual
2.12.3 Automatic Message Accounting (AMA)
The AMA feature is a billing feature that provides control, collection, and recording of
AMA data.
In case of an AW outage, the switching module is capable of storing 72 hours of
Automatic Message Accounting (AMA) data before requiring download to the AW for
storage on the hard disk.
A switching module circular AMA data buffer protects AMA data by ensuring that
certain pointers in the AMA storage area are not updated until the AMA data can be
retrieved once the AW is restored.
For more information on AMA, see 235-190-300, 5ESS Switch Billing Features and
Specifications.
2.12.4 AMADNS
Automatic Message Accounting Data Network Service (AMADNS) for DRM can be
either sender or receiver initiated.
