Security
The Remote Access feature allows people at remote locations to enter the
system by dialing the number of a line or trunk designated for remote
access. The system can be programmed to require the remote user to dial
a barrier code (a type of password) after reaching the system. In earlier
versions, the system-wide barrier code length is fixed at 4 digits. Release
3.0 allows a system-wide barrier code length ranging from a minimum of 4
digits to a maximum of 11 digits, with a default setting of 7 digits. SMDR
records are enhanced to provide information for remote access calls. If the
remote access call is received on a facility providing Caller ID information
(see below), the SMDR report can help trace the call.
Caller ID
Caller information (telephone number) is furnished to MLX display
telephones by an 800 GS/LS-ID module using the LS (loop-start) option.
This allows customers to screen calls prior to answering the phone, as well
as providing calling party information for use with various applications. This
function is available only when the customer subscribes to caller
identification service from the local telephone company, if the telephone
company supports that service.
Shared System Access (SSA)
A telephone may have up to 27 Shared SA buttons to expand extension
coverage.
Authorization Codes
The Authorization Code feature allows you to make calls using your calling
privileges when you are dialing from an extension other than your own.
When you enter your authorization code (ranging from 2 to 11 characters
and unique across the system), the privileges and restrictions assigned to
your home extension override the current restrictions at the host extension.
This includes toll restriction, outward restriction, Facility Restriction Level
(FRL), Allowed Lists, Disallowed Lists, Night Service Exclusion List, and
Dial Access to Pools. All other functions on the telephone are those of the
local telephone, not the home extension.
Authorization codes can also be used for the purposes of call accounting
through the SMDR printout. The SMDR account code field can hold the
authorization code extension number or the authorization code itself.
Direct Voice Mail
If your company has voice mail, this feature allows you to dial a co-worker's
voice mailbox directly without ringing that person's extension. Direct Voice
Mail is especially useful for transferring calls when a co-worker is not
available.
