Carrier-Grade Capabilities with Point Code Redundancy
SS7 signaling infrastructure is mission-criticalProtocols designed for maximum availabilityNMS’s SS7 redundancy benefits
No single point of failurePreserve stable calls and transactionsShare point code on two boards in different (or same) chassis
Uses distributed modelUtilizes on-board, high-speed, private Ethernet
Support in MTP3, ISUP, SCCP, TCAP, and TUP

SS7 Passive Monitoring Feature
Set of APIs and tools used in conjunction with a TX board to monitor up to 16 live SS7 signalling linksTypical applications
TestingLawful interceptCustomized SMS messages (international roaming greetings)
FiltersMTP2 signal units and headers can be filtered to massively reduce host loadHigher lever protocol layers such as ISUP and SCCP messages (based on DPC*, OPC* and/or SIO* fields)
Message collection and buffering to limit host interruptsNot supported
Injection of messagesDual mode (monitoring and SS7 signaling simultaneously)
* DPC: Destination Point Code
OPC: Originating Point Code
SIO: Service Indication Octet

Notes
Each monitored link requires 2 receive (RX) ports on the TX board
32 receive (RX) ports are available on the TX 4000:max of 16 monitored links per TX board
Receive (RX) level at TX board must be at 10 dB loss or better (includes protection circuitry and cabling)
