Used for acceptance testing, detailed trouble shooting, daily maintenance and performance analysis of telecoms networks and switches.

多達(dá)10種協(xié)議同時(shí)分析。Easy to use multi-link instrument with true multi-protocol analysis capability for up to ten protocols simultaneously.

Ability to store 1GB of data with 1ms resolution, filter trigger and perform sequence recording for easy analysis.

協(xié)議分析

協(xié)議分析功能捕獲發(fā)出的信號(hào)單元并以解碼的形式顯示。The protocol-analysis function captures signaling units and displays them in decoded form. The captured signaling units in the log are time-stamped with a resolution of 1 millisecond. The MPA 7300provides full correlation of signaling information recorded from all connected signaling links. Different protocol descriptions may be associated with the various signaling-link interfaces. National protocol descriptions can easily be customized. Automatic error recognition The unique MPA 7300 expert system automatically recognizes all invalid signaling messages and sequences (all valid messages and sequences are contained in the protocol description). In case of a signaling error (syntax error, messages out of sequence or timeout between two messages), the collected events will be stored with an error message in the log.

濾波器

In this context, filtering means controlling which signaling messages/sequences and alarms are stored in the event log. An event recognizer in the MPA 7300 is a mechanism that allows the user to look for individual signaling messages and alarms with a specific content – e.g. ISUP RELease messages with cause 17 “user busy”. Sequence recognizers are used to capture a complete sequence of events forming a meaningful transaction – e.g. a telephone call or a Service 800 IN transaction. Both event recognizers and sequence recognizers can be used as filter conditions. The user can select from a wide range of predefined “click-and-go” events and sequence recognizers. Up to 500 concurrent calls/transactions can be followed by a sequence recognizer.

觸發(fā)類(lèi)型

The MPA contains two trigger types: One start trigger for enabling (open) storage of events and one stop trigger for disabling (close). An event recognizer can be selected as start trigger. A timing offset or event-number offset can also be specified before the event recognizer.
