Remote Access 2 - 8 - AT&T SYSTEM 25 Manual

This feature allows a caller to dial into a System 25 from the public network using a
predetermined 7- or 10-digit number and use some features and services. The caller may be
required to dial a barrier (security) code after reaching the system. Using Remote Access, an
employee of a company with a System 25 PBX can access system facilities from home or other
remote locations. It is a valuable feature for salesmen on the road and people at small branch
offices.
If a barrier code is required, the specific barrier code used determines the calling privileges of
the user. Up to 16 different barrier codes can be administered for the system. If a barrier
code is not required, calling privileges for Remote Access calls are determined by a system-
wide default Class of Restriction (COR).
When the Remote Access caller is using a rotary voice terminal, dial pulses are not accepted
by the system after the special dial tone is returned. When dial tone times out, the call
routes to an attendant; if Night Service is active, the call routes to an administered "backup"
multiline station.
The System Administrator can assign CO, FX, or WATS trunks for Remote Access calls.
These trunks can be dedicated to Remote Access or shared with other kinds of calling. On
dedicated trunks, all incoming calls receive special Remote Access treatment. On shared
trunks, Remote Access is allowed only during Night Service times; at other times incoming
calls receive standard trunk treatment.
If DID service is in use, a valid DID number (otherwise unassigned) can be used for Remote
Access. Since the DID Remote Access number does not become "busy" until all DID trunks
are busy, multiple Remote Access calls can be active at the same time.
If Barrier Codes have been set up, Remote Access callers can activate the Forwarding feature.
See the "Remote Access Forwarding" section in the entry, "Forwarding," on page 2-43 for
complete information.
