User to User Signaling (UUS1) 
 

Definition  
This feature allows users to exchange messages during connection setup. The network transmits the messages transparently; checking only the length. Three UUS services are available:
 •   UUS1: Information is exchanged in control messages for connection setup and during connection release.
 •   USS2: Information is exchanged during the ringing phase. The number of messages is limited to two per trunk group. USS2 is available for telecommunications ports only.
 •   USS3: Information is exchanged during the active state of a connection.
HiPath 3000 currently supports only UUS1.

Supported features:  
 •   Name transfer via UUS for networked systems. Networking via ISDN dial-up lines. (Name transfer can be deactivated.)
 •   Name transfer from the CO via display messages.
