MERLIN LEGEND Communications System Release 5.0
Feature Reference 555-650-110
Features
Remote Access
Description
The Remote Access feature allows people to use the system by dialing the
number of a line/trunk designated for remote access. The remote user should be
required to dial a barrier code (password) after reaching the system. Beginning
with Release 3.0, the systemwide barrier code length is programmed for a
minimum of 4 digits and a maximum of 11. After gaining access to the system, a
remote user can do any of the following:
Dial extension numbers directly without going through a system operator.
Remote callers can call inside extensions, data workstations, or calling
groups just as if they were calling from an extension within the system.
Select a regular or special-purpose outside line (for example, a WATS line)
or a pool or Automatic Route Selection (ARS) line to make outgoing calls. If
the pool is busy, the system can be programmed to allow the remote user
to use Callback to queue a call for the busy pool.
Arrange to have calls forwarded, change the forwarding destination, or
cancel forwarding to a telephone inside or outside the system.
Remote access also allows remote system programming and maintenance.
Specific outside lines/trunks (ground-start, loop-start, emulated ground-start or
loop-start) are programmed for either dedicated or shared remote access. When
dedicated remote access is programmed for a line/trunk, all incoming calls on that
line/trunk are treated as remote access calls. When shared remote access is
programmed for a line/trunk, incoming calls on that line/trunk are treated as
remote access calls only when Night Service is activated on the system. Remote
access can be programmed for any outside line connected to the system, except
Direct Inward Dial (DID) or dial-in tie trunks. Loop-start lines programmed for
remote access should also be programmed for reliable disconnect.
!
SECURITYlALERT:
Avoid programming a remote access line as a destination for Night Service
on any published telephone number. Professional toll-fraud criminals scan
telephone directories for published local and 800 telephone numbers. Using
these numbers, they attempt to gain access to the system, then may use
such features as Remote Access to reach outside facilities from within the
the caller has dialed the eleventh digit—giving the impression that
additional digits are required—even if the barrier code length is
shorter.
SMDR registers 16 zeros for any remote access calls in which 3
failed attempts have occurred.
NOTE:
Calls made through remote access to locations outside the system
may vary in transmission quality.
