Digital Telephone IP Adapter description Standard 2.1
System security
There are two levels of security that you can set to control access from Digital
Telephone IP Adapter units to the RLC on the host PBX. This section describes
these security levels and how you can manage them using Remote Gateway
9100 Series Configuration Manager.
No security
When no security measures are used, the RLC accepts incoming calls from all
Digital Telephone IP Adapter units.
Use this level with caution as it exposes the RLC to unauthorized use. For
example, No security allows a user from an unauthorized remote site can
accidentally, or intentionally, connect to the RLC. With this connection made,
the unauthorized user can now place long distance phone calls through the RLC
and the host PBX.
Security identifier
When you choose the security identifier level of security, the Digital Telephone
IP Adapter automatically sends its configured security identifier (password) for
each connection request. The RLC compares the identifier configured to the
RLC port with the identifier assigned to the Digital Telephone IP Adapter. If the
identifiers match, then the RLC grants the requested connection.
If the identifiers do not match, then the RLC records an event in the Digital
Telephone IP Adapter system log. You can view the system log in Remote
Gateway 9100 Series Configuration Manager. The telephone displays
HOSTLESS MODE
,ïindicating that communications with the host PBX are
down.
