DISPCALL utility

This part describes the DISPCALL utility, DISPCALL uses, and restrictions
and limitations.

DISPCALL access level

DISPCALL is a low level internal diagnostic tool that monitors data
associated with the death of a call or with a call being held for analysis.
This data includes the originating and terminating ports of the call and the
software and hardware resources used on the call.
In addition to displaying data relating to calls that have died, DISPCALL
captures and displays data about calls in progress.
DISPCALL displays call processing data areas such as Call Condense
Blocks (CCBs), Call Data Blocks (CDBs), message buffers, extension
blocks, and protected and unprotected data for call processing agents. A call
processing agent is an originator or receiver of a call in the system.
DISPCALL data can be displayed in either formatted (English text) form or
in hexadecimal form. The format routines can be accessed from the
DISPCALL command level. For more information on the DISPCALL
command level, refer to Chapter 3 on page 3-1.
Access the DISPCALL utility by entering the DISPCALL command and the
appropriate parameters while in the Command Interpreter (CI) access level
of the MAP. Refer to Chapter 3 for correct command syntax.

conditions involves looking for missing or corrupted data on a repeating
equipment unit. For such analysis it is recommended that hard copies of the
DISPCALL outputs be retained.
