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.
