igCurrActiveCalls

ZhoneGR303-MIB · .1.3.6.1.4.1.5504.4.3.1.1.1.13

Object

column calls Unsigned32

The number of calls currently in use. 
igCurrActiveCalls is used in conjunction with 
igMaxActiveCalls, the maximum number of calls 
available, to provide a metric for describing 
current utilization.  Does not imply that a call
has completed, but rather that the DS0 time-slot
has been allocated for a call by the GR-303
interface.
              
The DS1 frame is composed of 24 consecutively
numbered (1-24) time-slots (channels or DS0s).
              
Maximum number of currently active calls is the 
maximum number of DS1s assigned to the IG times
the maximum number of channels or DS0s per DS1 
less 2 or 4 channels for primary only EOC/TCM
and primary/secondary EOC/TCM = 
({1..28} * 24 - {2,4}) = {22..670}
              
28*24 equals maximum number of DS0's on a DS3, 
with 0 signaling channels. If you have one 
28-T1 IG with no redundancy you can have 
672 - 2 signaling DS0's , or 670, or 670 
DS0's available for active calls.
              
If you have a single-T1 IG, you have only 
24 - 2 signaling DS0's, or 22,  DS0's 
available for active calls.
