Release Link Trunks (RLT)
Release Link Trunks (RLT) are used between switch locations to provide
centralized attendant service or automatic call distribution group availability.
Remote access trunks
Tie trunks
Tie trunks carry communications between Communication Manager and other
switches in a private network. Several types of trunks can be used, depending on
the type of private network you establish.
Wide Area Telecommunications
Service (WATS)
Wide Area Telecommunications Service (WATS) trunks allow you to place
long-distance outgoing voice-grade calls to telephones in defined service areas.
The calls are priced according to distance in the service area, length of the call,
time of day, and the day of the week.
Public networking and connectivity
Caller ID (ICLID) on analog trunks
Caller ID on analog trunks 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.
Caller ID (ICLID) on digital trunks
In the United States, the user’s telephone displays calling party information (if the
telephone is a display telephone). Name and calling number are available from the
US central offices.
This feature may be used in countries that comply with either US. The display of
name and number will work with all Communication Manager digital telephones
(DCP and BRI) equipped with a 40-character or a 32-character alphanumeric
display.
