Notes:
1. Depending upon administration details, unauthorized calls may be blocked based upon 1s, 10s, 100s, and/or 1000s digit.
2. Equivalent DID is the capability for a switch to link to another switch that does not have DID. The ARS feature sends digits
including, if necessary, the remote access number, barrier code, and extension number. To the calling party, the number dialed is
the same as a DID number.
3. System 85 uses the ''Override'' feature to perform this function.
4. Although System 75 does not provide the ''Extension Number Portability'' feature, the ''Extension Number Steering'' capability
can be provided by the UDP software and used to port a maximum of 240 extension numbers (per System 75 switch) among all the
nodes in a portability subnetwork.
