Remote Access

Planning Form Instructions
In the "Short Hold Disconnect Interval" column of Form 2c, check "Yes" next
to any lines that you want to change from the long (450mn) interval to the
short (50 ms) interval.
Note: Be sure you have checked "No" for "Loop-Start Reliable Disconnect" if
your local telephone company uses a Short Hold Disconnect interval.
Use these instructions only if remote users need access to the system.
Remote Access allows people to use the system from a remote location. A
person working away from the office can call into the system on one of the lines
programmed for remote access, The system answers the call, and the user can
then do the following:
dial extension numbers directly without going through the system operator.
This means that a remote employee can call internal telephones, data
terminals, or calling groups just as if the call were being placed from an
internal telephone.
select a line pool, or special-purpose line, such as WATS or FX, to make
outgoing calls. If the line is busy, you can specify that the remote caller is
eligible for Automatic Callback. This means the caller can remain on the call
and not have to keep calling back to get an outgoing line.
Note: Calls made via Remote Access to locations outside the system may
vary in transmission quality
activate, change, or cancel the Call Forward telephone or extension number
programmed on a telephone.
Remote Access also allows remote system programming and maintenance by
AT&T or your authorized dealer.
To have Remote Access, the control unit must contain one or more 400,
400 GS/LS/TTR, 008 OPT, or 012 modules. These modules have touch-tone
receivers, which are required to make the Remote Access feature work. Check
the Control Unit Diagram on Form 1 to verify that one of these types of modules
is present before you begin planning Remote Access.
Note: The lines assigned Remote Access do not have to be connected to the
module with the touch-tone receiver.
It is recommended, but not required, that Remote Access lines appear on line
buttons on an operator console. This allows the operator to manually disconnect
a call in case an incoming call on that line does not disconnect properly.
