This field specifies the type of trunks associated with this trunk group

The only acceptable values are tone and rotary. If the field is set to automatic or mf, then the value of tone is used instead. Note that this does not apply to DS1 PRI links.

This value is used in the routing table

This value is only necessary if the Dial Access? field is set to y. If that field is set to n, the TAC value is not pushed down to the media gateway.

There may be more than one port within a trunk group definition that pertains to a given media gateway

This only applies for DID analog trunks or for DS1 tie trunks. Note that this does not apply to DS1 PRI tie trunks.

This field contains a value only when the Digit Treatment field is set to insert1, insert2, insert3, or insert4
