The M3UA Message Handling Distribution (MHD) table is used for ISUP traffic routing in a licensable SP2000 deployment only.

The M3UA MHD records are used to determine which Gateway Controller (GWC) or Call Agent (for example, C20) the ISUP message is destined to based on the incoming Routeset and CIC value.

A maximum of 400K records can be created in this table through proprietary M3UA messages from the Call Agent. The C20 ASP will download the MHD table when their ASP associations are active.
