Assigning Features to Data Stations
Calling Restrictions. These features inhibit line access, and allow
companies to control and manage communications costs for outgoing
data calls.
Data Status. This button allows monitoring of station activity (busy, not
busy) at any data station. Although this feature is similar to having an
Inside Auto Dial or Signaling button because it lights the green LED to
indicate extension-busy status, pressing the button has no effect. It does
not dial the data extension number. Thus, the button does not interfere
with a data call in progress, unlike an Auto Dial button, which dials its
programmed number.
Personal Lines. This feature provides direct access from an ISDN
terminal adapter data station to outside lines supporting the PRI, NI-1
BRI, or T1 Switched 56 interface.
Idle Line Preference. This feature automatically selects the first available
line for data calls.
Last Number Dialed. This feature automatically places a call to the last
number dialed from that data station. Dialing sequence must include
dial-out code for outside calls.
Personal Speed Dial. These 2-digit numbers are programmed for quick
dialing of frequently used numbers. The dialing sequence requires a dial-
out code for outside calls.
Privacy. This feature prevents loss of data by ensuring that data
transmission is not interrupted accidentally. Privacy is automatic for data
calls on ISDN terminal adapter data stations and on analog voice and
modem data stations. Privacy is activated manually on modem data-only
stations.
System Speed Dial. This feature allows quick dialing of numbers that are
used often systemwide. The dialing sequence requires a dial-out code for
outside calls. The System Speed Dial feature is programmed systemwide
for both voice and data stations. Follow the instructions earlier in this book
to assign System Speed Dial codes to data station users.
IMPORTANT:
Certain system (voice) features interfere with data connections. System features
that must be disabled are the following:
Voice Announce
Call Waiting
Automatic Callback
