ISDN Use ISDN trunks when you need digital trunks that can
integrate voice, data, and video signals and provide the
bandwidth needed for applications such as high-speed data
transfer and video conferencing. ISDN trunks can also
efficiently combine multiple services on one trunk group.
You cannot enter isdn unless the ISDN-PRI field, the
ISDN-BRI Trunks field, or both have been enabled on the
System-Parameters Customer-Options screen.
RLT Release Link trunks work with Centralized Attendant Service
in a private network.
Tandem Tandem trunks connect tandem nodes in a private network.
Tandem trunks allow inband ANI.
Tie Use tie trunks to connect a switch to a central office or to
another switch in a private network. Tie trunks transmit dialed
digits with both outgoing and incoming calls, and allow inband
ANI.
WATS Use WATS trunks to reduce long-distance bills when your
organization regularly places many calls to a specific
geographical area in North America. Outgoing WATS service
allows calls to certain areas (“WATS bands”) for a flat monthly
charge. Incoming WATS trunks allow you to offer toll-free
calling to customers and employees.
