Dissociated telephones 
When a user requests to associate a telephone with PSA, any other telephone 
using that extension is automatically dissociated. It is possible to place emergency 
calls from a dissociated telephone, provided a COR has been assigned to 
dissociated phones on the Feature-Related System Parameters screen. 
PSA allows a dissociate request from a bridged appearance. However, when you 
execute a dissociate command from Terminal B, even if you are on a bridged 
appearance of an extension belonging to Terminal A, you dissociate the station 
belonging to Terminal B.
The dissociate function within PSA allows a user to restrict the features available 
to a phone. When a phone has been dissociated using PSA, it can be used only to 
call an attendant, to place an emergency call, or to accept a Terminal Translation 
Initialization (TTI) or PSA request. To enable users to make other types of calls 
from dissociated sets, you must establish a class of restriction for these phones. 
See 
‘‘Setting up Personal Station Access’’ on page 287
 for more information. 
NOTE:
Once a station has been associated with a terminal, anyone using the 
terminal has the capabilities of the associated station. Be sure to execute a 
dissociate request if the terminal can be accessed by unauthorized users. 
This is particularly important if you use PSA and DCP extenders to permit 
remote DCP access.
Interactions
Adjunct/Switch Application Interface
An ASAI link cannot use this feature because ASAI uses a BRI port. Do 
not assign to an ASAI link a Class of Service that allows PSA.
Bridged Appearance
When you execute a PSA dissociate request for the principal station, its 
bridged appearances remain active if the stations on which they appear 
have not been dissociated. When a call is made to the principal extension, 
any of its bridged appearances that can be alerted are alerted. Otherwise, 
the call follows the principal extension’s coverage path.
PSA dissociate requests executed at a bridged appearance dissociates the 
station that the bridged appearance is on.
Call Management
PSA dissociate automatically logs out an ACD agent.
