This mib describes the per product registrations that are then
used for the sysObjectId field.
        
The format is  1.3.6.1.4.1.5504.1.x.y.z where 5504 is our 
enterprise ID. 
        
X is the product type so:
        X = 1 - PLS
        X = 2 - CPE
        X = 3 - MUX
        
Y is the product model type:
        Y = 1 - BAN (for the PLS product)
              Etc.
        
        Y = 1 - IAD-50 (for CPE equipment)
                  Etc.
                   
        
Z is just an incremental field which needs to be documented 
what value maps to which product model.
        
For example, an IAD-50 could be .1.3.6.1.4.1.5504.1.2.1.1. A 
new model of the iad-50 that for some reason we would want 
to differentiate functionality would be
 .1.3.6.1.4.1.5504.2.1.2.
