4 Project No.: R1TRFTTE 4 Test report summary Testing was completed against all relevant requirements of the test standard. The results obtained indicate that the product under test complies in full with the requirements tested. The test results relate only to the items tested. 4.1 Revision History R1TRFTTE, Febuary 1, 2010 Corrected part numbers on page 1 and 3 to correct RSVLC-102A to RSVLC- 1002A. 5 Equipment under test 5.1 EUT Description The EUT is a PC based VoIP Gateway card. It provides public telecommunication network access via up to 2 Primary Rate ISDN ports. The card has different variants which allows the card to host the following configurations: 1 port Model A101. The differences between models are the addition of a DSP for echo cancellation or the use of PCI Express as opposed to PCI architecture 2 ports Model A102. The differences between models are the addition of a DSP for echo cancellation or the use of PCI Express as opposed to PCI architecture The A101 is a depopulated version of the A102. The A101/A102 shares the same drivers, F/W and H/W with the A104/A108 product evaluated in project TRFTTE. The exception is the number of ports on the framer/transceiver chip(s) and the line transformer. 5.2 Technical judgement The following technical judgements were made during the assessment: Technical judgement 1 The drivers, F/W and H/W are of the same family for the A102 and A104. The difference from the previously evaluated A104 is the layout of the analog portion of the circuit the number of ports in the framer (1 vs. 4) and the line transformer brand and number of ports. It was judged that the layers 2 and 3 did not have to be retested on the A102 / A101 and compliance to the requirement would be based on Nemko Report TRFTTE. It was further judged that only the electrical portions of the layer one tests were required to fully evaluate this variant of the product Technical judgement 2 The bus interface of the base card was judged as not affecting the evaluation; therefore only one variant was tested. As the A04 report used the PCI version this test used the PCI express version for completeness Technical judgement 3 The A102 board has 2 variants with one or two ports populated. It was judged that only one port of one variant required testing. The two-port card was tested on port one (labeled as A ). 5.3 Modification performed during the assessment No modifications were made during the assessment. Page 4 of 61
