Acme Packet 4600 Mib help

I've downloaded the MIB package and opened it to look at the individual notifications. What I can't find is the relationship of the number notification the SBC is sending, relative to what it actually is.

Example -

We're getting a generic trap from our system that looks like this.

Generic: 6; Specific: 16; Enterprise: .1.3.6.1.4.1.9148.3.2.6;

Variables:

[1] .1.3.6.1.4.1.9148.3.2.5.20.0 (Integer): 0

[2] .1.3.6.1.4.1.9148.3.2.5.21.0 (Integer): 3

[3] .1.3.6.1.4.1.9148.3.2.5.22.0 (OctetString): x.x.x.x:59316

How can I tell what it's telling me, so i can see if it's valid and something we want to be alerted on? ( the "x"s are our IP's)
