header mode The Avaya MPS parameter that determines how host message headers

are translated:

• if header mode is enabled, COMMGR translates header messages

• if header mode is disabled, the applications must translate header

messages

The Avaya MPS supports 24-byte header mode by converting into a

PACE structure.

Use a PeriProducer Environment block to enable or disable header

mode. From the Environment Class menu, select Host Environment.

command man page commgr headermode.

High-Level Data Link

Control

See HDLC.

high water mark A limit maintained by the system for MultiMedia files. The high

water mark signifies the point when available message space is

depleted. When the high-water mark is exceeded, SMP returns

mmfhigh to the appropriate administrative application. No more

messages should be recorded at this point (until the application

receives mmflow).

You can record CMR messages directly into application specific

MultiMedia files. Set the water mark limits in the configuration file

smp-mmf.cfg for each MultiMedia file used for recording; the

high-water mark is set on a per MultiMedia file basis.

For additional information, see the Avaya MPS System Reference

Manual and the Avaya MPS Application Programming Reference

Manual.

Contrast with low water mark.

man pages smp hwm, smp mmfadmline.

HOM Handle Object Manager. Used to keep track of all handle objects

currently in use by an MX application; prevents a handle object or its

data from being freed by one thread while still being accessed by

another. A handle object is a data structure that represents an MX

Telephony/Media object such as a phone line.
