examined to determine if the message can be
processed. Gateway Screening enables a network
management mechanism to prevent unauthorized
access, and thus protects network integrity.
Multiple Originating Point Code
The Alcatel 5070 SSG ANSI supports Multiple
Originating Point Code definitions, which allow
link sets to have a different adjacent point code
definition than the main STP point code. This
flexibility allows for ease of installation into
networks in which the Alcatel 5070 SSG ANSI
is replacing previously installed STP systems,
and in cases where network signaling is being
consolidated to a smaller set of STP systems
to provide economic savings in operations
and maintenance.
This functionality allows introduction or
consolidation of new STP systems into the
network without impact to subtending and
interconnected network elements. Rather than
having to change destination point codes and
adjacent node point codes, subtending and
interconnected elements retain their routing
definitions, while the new system is introduced
into the network via facility switchovers.
OSS Interfaces
The Alcatel 5070 SSG ANSI provides interfaces
to Telcordia operations support systems (OSSs)
for SS7 routing provisioning, LNP provisioning,
data collection and monitoring. The system
includes functionality based on GR-310 and
GR-778 for interface to the Telcordia Signaling
Network Activation Manager and the Telcordia
Network Performance Manager. Also, a CMISE
interface for LNP provisioning either to the
Signaling Network Activation Manager or to
an LSMS is provided per SR-4384. In addition
to monitoring capability, the system provides a
serial logging channel interface for delivery of
alarm and user interface command information.
