Tools that restrict unauthorized outgoing calls

Digit conversion
Digit conversion allows you to identify numbers, area codes, or countries you do
not want called. Whenever the numbers entered correspond to the numbers on
the conversion list, the numbers are given a different value, such as 0, and then
forwarded to the new destination, such as the attendant console.
■ For DEFINITY G1 and G3i, the conversion can be to “blank” (intercept
tone), or to a Route Number Index (RNX) private network number, where
Private Network Access (PNA) software is required to route the call
through AAR.
■ For DEFINITY G2 and System 85, the conversion is to an RNX private
network number, and AAR software is required.
■ For DEFINITY G1, G2, G3i, and System 85, once the call is sent to AAR
software, the RNX can be translated as “local,” and the call can be directed
to an internal station or to the attendant console.
Station security codes
Station security codes (SSCs) are used with two features: Personal Station
Access and Extended User Administration of Redirected Calls. Starting with
DEFINITY ECS Release 5, the Security Violations Status report shows the 16
most recent invalid attempts of SSC use. The report is refreshed every 16
seconds, and it shows the date, time, port/extension, FAC, and dialed digits for
each invalid attempt. Enter the monitor security-violations
station-security-codes command at the prompt to access this report.
SSC violations are summarized in the Security Violations Summary report. Enter
the list measurements security-violations summary command to access this
report.
SSC input entry has a pre-administered security capability. For details, refer to the
‘‘Personal station access’’
section in this chapter.
Finally, SSCs should be changed about once every six months.
Personal station access
The Personal Station Access (PSA) feature allows multiple users to work at the
same voice terminal location at different times. PSA provides capabilities that are
similar to TTI, but for a single station. This feature is available starting with
DEFINITY ECS Release 5.
Each PSA user must have a station security code (SSC), which includes as many
as eight digits.
