Security

Introduction
The MIG RLC and Remote Office 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 Office 9150 unit's calling line
identification (CLID) is compared with its PSTN number configured on the
MIG 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 circuit-
switched network. If this level is chosen, a security identifier must be
configured on both the Remote Office 9150 unit and the MIG RLC port to
which the unit is assigned. When a connection between the host PBX and
Remote Office 9150 unit is attempted, the security identifiers are compared.
If they match, the connection is established. If they do not match, the host
PBX drops the call.
