A separate trunk group is needed for Operator Services due to network requirements which dictate that Multi-Frequency (MF) signaling be used.

In areas where there are multiple NPA's, a separate operator group is required for each separate NPA. For instance in Utah we have 435 and 801 NPA. One operator group for NPA 435 is required plus one group for NPA 801.
