When the system administrator assigns lines to a basic telephone, the

administrator must provide the user with a list of codes for the lines

and/or line pools he or she can access.

While Night Service with Outward Restriction is in effect, people with

basic telephones cannot enter a password to make calls. To allow them

to make after-hours calls, the administrator must assign these basic

telephones to the Exclusion list. (See “Night Service.”)

Basic telephones can receive ringing intercom calls, but not intercom calls

with voice announcement.
