70 Remote Gateway 9150 Installation and Administration Guide
Planning for Remote Gateway 9150 unit installation Standard 3.1
Security
The RLC and Remote Gateway 9150 unit offer the following types of security:
!
security level and, if required, security identifier to prevent toll fraud on the
host PBX
!
two levels of administration passwords to secure node configurations
Toll fraud
You can minimize toll fraud on the PBX by implementing one of the following
levels of security:
!
Caller ID
When Caller ID is selected, the Remote Gateway 9150 unit’s calling line
identification (CLID) is compared with its PSTN number configured on the
RLC port when a connection to the host PBX is attempted. If they match,
the connection is established. If they do not match, the host PBX drops the
call.
Caller ID authentication cannot be performed over the IP network.
!
security identifier
You can use security identifier authentication over the IP or PSTN. If you
choose this level, you must configure a security identifier on both the
Remote Gateway 9150 unit and its assigned RLC port. When an incoming
call attempts to initiate a connection between the host PBX and Remote
Gateway 9150 unit, Remote Gateway 9100 Series compares the security
identifiers. If they match, the attempted connection succeeds. If they do not
match, the host PBX drops the call and the connection fails.
Data network security
The Remote Gateway 9150 solution does not provide for data network security.
If security on the data network is an issue, security must be implemented on the
data network devices.
