Bellcore calling name ID
This feature allows the system to accept calling name information from a Local
Exchange Carrier (LEC) network that supports the Bellcore calling name
specification. The system can send calling name information in the format if
Bellcore calling name ID is administered. The following caller ID protocols are
supported:
■ Bellcore (default) - US protocol (Bellcore transmission protocol with
212 modem protocol)
■ V23-Bell - Bahrain protocol (Bellcore transmission protocol with
V.23 modem protocol).
Block collect call
This feature blocks collect calls on class-of-restriction basis. This feature is
available for any switch that uses the Brazil country code. If enabled for a station,
all trunk calls that terminate to the station will send back a double answer to the
central office (CO). This double answer tells the CO that this particular station
cannot accept collect calls. The CO then tears down the call if it is a collect call.
Busy tone disconnect
In some regions of the world, the CO sends a busy tone for the disconnect
message. With busy tone disconnect, the switch disconnects analog loop-start CO
trunks when a busy tone is sent from the CO.
