Test results

All BSIA comms equipment manufacturers have attended the BT facility in Swansea and tested their core products against the BSIA test plan. The results of these have been published on both the BT “Switched on” website and BSIA website.

The test results focus on the main potential failure mode for 21CN, which is additional network delay.  They also provide a 21CN compatibility test.

The latest issue of results is Issue 3 dated  23/04/10.  Changes to the previous issue are shown in red.  Click here for Issue 3.

Reading the results on their own may not provide a straightforward answer to whether certain equipment is at risk, as there are two other factors that can affect the overall delay of alarm signals; these being the type of receiving equipment and the type of network it is transmitted on. To assist with this, BSIA has also produced a web based “risk calculator” which allows you to enter the two fundamental values under consideration, those being the Communicator delay and the Receiver processing delay. Once these values are entered, a graphical representation is produced showing you the potential risk of failure on each of the known network routing configurations.

The web-based calculator is available by clicking here.

NB. Whilst every effort has been made to ensure that the results are full and reliable, the BSIA cannot accept any liability for the accuracy of the results or responsibility for any reliance upon the results. The tests which gave rise to the results were dependent upon British Telecoms technical equipment and were carried out by each contributing manufacturer themselves.
