     isdnd.rates -- isdn4bsd ISDN management daemon rates description file

     The file isdnd.rates contains descriptions	how long charging units	last
     at	a given	time of	day, day of week and the distance to the destination.
     If	this file is available,	this information may be	used by	the isdnd(8)
     ISDN connection management	daemon to calculate the	short hold time	for a

     The format	of a rate entry	line is	as follows:

     The first field, the (rate-code) defines a	collection of rates (for each
     day of the	week) which can	be referenced in the isdnd(8) configuration
     file isdnd.rc(5).	This field must	start with the identifier "ra" fol-
     lowed by a	digit in the range of zero to four.

     The second	field, the (day-number)	selects	the day	of week	for which this
     entry defines the rates, where 0 stands for Sunday, 1 for Monday and so
     on	until the digit	6 which	stands for Saturday.

     The rest of the line consists of one or more space	separated fields which
     have the following	syntax:


     Start_hour	and start_minutes define the begin of a	time section and
     end_hour and end_minutes define the end.  Charge_unit_length define the
     length of a charging unit in the previously defined time section.	No
     spaces or tabs are	allowed	inside this field.  The	hour and minutes spec-
     ifications	MUST have exactly 2 digits, in case just one digit is needed,
     a leading 0 must be used.

     For example,


     defines, that between 2:00	PM and 6:00 PM the length of one charging unit
     lasts 90 seconds.

     /etc/isdn/isdnd.rates  The	default	rates specification file for the isdnd
			    ISDN daemon.

     The line:

     ra0 0 00.00-05.00:240 05.00-21.00:150 21.00-24.00:240

     defines the unit lengths for a Sunday.
