Feature Reference
Personal Station Access
Detailed description
The preferences and permissions that are retained with PSA include the definition of terminal buttons,
abbreviated dial lists, and COS and COR permissions assigned to the your station. Extensions that do not
have a COS, such as EAS agents or hunt groups, cannot use PSA.
PSA functions only on analog, hybrid, and 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 media servers or 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.
When a call that goes to coverage from a PSA-disassociated extension, Communication Manager sends a
message to the coverage point indicating that the call was not answered. If the coverage point is a display
phone, the display shows "da" for "don't answer." If the coverage point is a voice messaging system, the
VM system receives an indication from Communication Manager that this call was not answered, and
treats the call accordingly.
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 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
305 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.
