Purpose: 
    Contains H.323 related timer values. Timer values are only
	used to clean up state in case of client error and are not
	aggressive.

History:

    1. created as cb931pdu.h for q931 consts (rajeevb, 19-Jun-1998)
	2. now contains all timer values for q931 and h245 (rajeevb, 19-Jun-1998)
