Controlling ISDN Access

iMarc units with a DBM can limit access through the following methods:

ISDN Call Security

The iMarc unit uses the Caller Identification Method to screen calls and avoid
accidental or intentional disruption of network traffic. The answering DBM only
accepts calls with valid calling number identifiers or phone numbers.
When the ISDN DBM interface is enabled and Caller Identification Method is set to
Caller ID, the DBM takes advantage of ISDN services for network backup and
Calling Number Identification Service (CNIS) to provide backup security. ISDN
assures the integrity of calling party identifiers. The DBM uses the calling party
identifier to identify the calling unit and switches PVC connections as specified by
the user. No additional security is required.
When the ISDN DBM interface is enabled and Caller Identification Method is set to
Proprietary, the DBM queries the originating unit for its Local Phone Number to
identify the calling unit. If the returned number is in one of the unit's Inbound
Calling IDs, the call is accepted. If not, or if the queried unit does not respond
within five seconds, the unit drops the call.
See Caller Identification Method in the
additional information.
