Thanks for the info, Bob. This is *close* to what I want.
Since they're counters, I can use this to watch the total number of calls per polling interval (in my case, 5 minutes). And although that's not what I was looking for, I'm going to graph it anyway, because the total number of inbound & outbound calls is pretty interesting as well.
However, what I'm trying to do is track the utilization of my PRI's. In other words, what percentage of B channels are in use at particular times of day? Obviously, I'll only have samples at the polling intervals, but at least it'll give me something to go with.

David,
Correct me if I'm wrong, but it appears that you are looking for the number
of calls connected at one polling interval (e.g "....poll with MRTG so I end
up
with the number of channels that list a "4" for their status?");
You could try looking at this table.
"isdnSigStatsInCalls" "1.3.6.1.2.1.10.20.1.3.3.1.1"
"isdnSigStatsInConnected" "1.3.6.1.2.1.10.20.1.3.3.1.2"
"isdnSigStatsOutCalls" "1.3.6.1.2.1.10.20.1.3.3.1.3"
"isdnSigStatsOutConnected" "1.3.6.1.2.1.10.20.1.3.3.1.4"
IsdnSignalingStatsEntry ::= SEQUENCE {
isdnSigStatsInCalls Counter32,
isdnSigStatsInConnected Counter32,
isdnSigStatsOutCalls Counter32,
isdnSigStatsOutConnected Counter32,
isdnSigStatsChargedUnits Counter32
}
isdnSigStatsInCalls OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of incoming calls on this interface."
::= { isdnSignalingStatsEntry 1 }
isdnSigStatsInConnected OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of incoming calls on this interface
which were actually connected."
::= { isdnSignalingStatsEntry 2 }
isdnSigStatsOutCalls OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of outgoing calls on this interface."
::= { isdnSignalingStatsEntry 3 }
isdnSigStatsOutConnected OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of outgoing calls on this interface
which were actually connected."
::= { isdnSignalingStatsEntry 4 }

Bob
