Personal Station Access 
20
Calls an employee originates from the station are recognized and displayed as the 
employee’s calls, and calls routed to the employee’s extension route to the voice 
terminal “associated” with that extension. 
A telecommuting or hoteling employee can also use PSA when working at home. 
For example, the employee installs a DCP terminal and a DEFINITY Extender at 
home, calls into the system, and uses PSA to associate the remote phone with their 
extension. The system associates the home terminal — that is, recognizes the 
home terminal as having the employee’s preferences and permissions. When 
someone calls the employee’s extension, the call rings at the employee’s home. 
When the employee no longer needs to use the office, they “dissociate” from the 
terminal. 
PSA requires users to enter a security code and can be used on-site or off-site. 
PSA-invalid attempts generate referral calls and are recorded by Security 
Violation Notification (SVN) software, if that feature is enabled. If a user 
interrupts the PSA dialing sequence by pressing the release button or by hanging 
up, the system does not log the action as an invalid attempt.
Detailed description
The preferences and permissions that are retained with PSA include the definition 
of terminal buttons, abbreviated dial lists, and class of service (COS) and class of 
restriction (COR) permissions assigned to the your station. Extensions that do not 
have a COS, such as Expert Agent Selection (EAS) agents or hunt groups, cannot 
use PSA.
PSA functions only on analog, hybrid, and Digital Communications Protocol 
(DCP) terminals. Many types of DCP terminals exist, and these terminals have 
different types and numbers of buttons. If you attempt to associate DCP stations 
with DCP terminals that have incompatible buttons, button mapping is 
unpredictable. This is also true of hybrid terminals. If you want a user to be able to 
use the terminal buttons and to have consistent displays, associate stations with 
terminals of the same type.
Stations and ports on different switches cannot be PSA associated. This includes 
stations on different switches (or nodes) within Distributed Communications The 
system does not limit the number of stations that can use PSA. However, heavy 
use of the associate and dissociate functions may temporarily impact system 
performance.
