A signed off station is a station to which no pen (module) is assigned. From a security point of view the status is SIGNED_OFF. In this status the station cannot be reached and cannot execute any action itself with the exception of the following functions:

Its class of service, group membership etc. remain unchanged. A previously activated FWD remains active.

A signed on user is a user configuration properly assigned to an enabled PEN. The dependability status SIGNED_OFF is not set.

An ID card user (anates) is a user without a specific telephone. These users identify themselves by means of their ID card and their PIN at any suitable stations/telephones in the system. Depending on the type of telephone used, such users may not always be able to access the entire range of features for which they are authorized. The device at which an ID card user identifies himself or herself remains configured under its original station number, and is administered with this number.

An identified ID card user is an ID card user who has identified himself/herself at a suitable telephone assigned to an enabled PEN. Such a user is regarded by the system as a standard, signed on telephone user in all respects, except that no group memberships (e.g. PU-group or CHESE group) are possible. These users sign off by removing the ID card from the card reader. However, ID card users are not placed in SIGNED_OFF status.

PENs with the CONNECTION_TYPE "SIGNED_OFF". For multiple device PENs, the dependability status of a circuit will be MULTIPLE_LINE, and only the CONNECTION_TYPE of the individual TSIs will be SIGNED_OFF (c.f. DISPLAY-SDSU, DISPLAY-BCSU).

PENs with a CONNECTION_TYPE other than "SIGNED_OFF". For boards with multiple-device PENs, the CONNECTION_TYPE of the circuit will always be MULTIPLE_LINE, whereas the TSIs can be free, signed off or assigned.
