MultiDSLA

MultiDSLA is a highly scalable solution for the measurement of network speech transmission performance to meet the needs of Enterprises, Network Operators, Service Providers, System Integrators and Equipment Developers.

MultiDSLA sets up calls and makes measurements between any end points in the voice network. Tests occur according to a pre-defined schedule or on demand with a simple to use graphical representation of the network. Comprehensive speech performance testing has never been this quick, simple and free of test design errors.

Voice communications systems delivering poor or erratic quality of service can have a significant negative impact on corporate image, customer satisfaction and employee productivity. Voice/data convergence, packet transmission techniques and the use of compression codecs can all bring cost benefits which are too easily lost when performance is not optimised. MultiDSLA equips you to manage Quality of Service, powerfully and effectively.

MultiDSLA - a new generation of network and equipment test systems incorporating the best features of the two channel DSLA and adding many new capabilities. MultiDSLA offers unrivalled ease of use and will perform the most complex test processes.

MultiDSLA brings a new concept in the evaluation of Conference Bridge performance. Many calls can be placed from the different types of nodes to the Bridge. Automatically, the speaker node rotates through each node with all the other nodes listening and measuring. The results build confidence in the Conference Bridge capability to support network translation from SIP to analogue, ISDN to H.323.

The Minimum Network Test System for VoIP comprises a DSLA and a pair of Virtual Nodes. Calls between DSLA channels, perhaps connected via an IP Phone handset, will correlate well with the end user experience. Calls between VNs yield useful data about the capability of the network to support speech traffic under various load conditions. Calls from VN to a DSLA segment the network to help identify problems and assess the effectiveness of engineering solutions.

The Telephone Tester option applies MultiDSLA and its powerful automation to the acoustic measurements of handsets. Automatic equalisation of the artificial mouth and level adjustment prepares the system for accurate measurments of loudness ratings and frequency responses. ITU-T Rec. P.310 and P.311 are fully scripted.

MultiDSLA will scale to support many nodes. The limitation is only in the processing power of the PCs running the application, SQL server and Metrics Processor. A large Enterprise network might include 200 sites around the world with one or more nodes at each site.

MultiDSLA allows the user to configure results presentation to meet specific requirements, selecting from a range of options for logging, setting limits, handling exceptions and generating alarm messages. Summary, Exception, Connection and Trend Reports are immediately available within the application or remotely over any convenient IP connection.

The new Perceptual Expectation Gap TM view of the speech quality between end points offers a convenient way to compare performance across different network technologies or against Service Level Agreement requirements.

 Product Background

Trusted Malden Electronics speech measurement know-how is now delivered in a modular, scalable architecture, exploiting the world renowned DSLAII, a state of the art standalone measurement system for speech performance assessment, with a reputation for unparalleled precision, capability and flexibility. DSLAII has become the reference measurement system in applications ranging from voice technology core development work to network operations.

The MultiDSLA combines this same measurement technology in a multi-node architecture with a very powerful set of management tools and report generators; even enabling simultaneous use by different people in different locations.
