9 Page 9 of 42 Traceability of connecting hardware performance applies at Telebox Industries Corp. by part number and the production week printed on the printed wiring board. Lot number of delivered connectors is used for traceability of all contained single components. The quality assurance system at Telebox Industries Corp. is recognized by the following companies and organisations: TÜV Rheinland Group 3P Quality records of subsuppliers are kept and maintained by Telebox Industries Corp. A maximum 3 % failure rate applies for all delivered materials and components. All supplied printed wiring boards are identified by part number, and with producer code and production week. Plated contact wires and IDC contacts are delivered with certificates for plating and materials, and are containing test data for gold and nickel thicknesses and base metal composition. The first delivery is identified by a full quality report. Later deliveries includes thickness data only. All supplied contact components are stored using humidity and temperature controlled conditions. Batch size of printed citcuit boards is typically between 1000 and 5000 pieces. Batch sizes of produced connectors are 25 pcs for patch panels and 500 pcs for keystone jacks. Visual inspection of printed wiring boards for each individual connector batch is carried out initially on two patch panel printed wiring boards and 40 keystone jack printed wiring boards. Printed wiring boards for soldering and press-fit mounting are identified by different numbers due to the more strict requirements to hole diameter tolerances applicable for press-fit mounting boards. All stored components are scrapped if not used after five years. The year is identified by a separate colour coding and each quater is identified by a separate number. A new type of connector and each new batch of printed wiring board are approved by complete electrical measurements of two mounted samples. The first sample is a first production sample and the second sample is randomly selected from the first connector production batch. The printed wiring board for the first production sample is taken randomly from the printed wiring board delivery All measuring and test equipment were properly identified with a tag showing instrument number and calibration expiration date. Calibration data were properly filed. Calibration is carried out by external source (company IPE). Calibration of network analysers is done every 24 months. 12 persons (21 % of total staff) and equipment operators are working with quality assurance and quality control at Telebox Industries Corp. Incoming control External sub-suppliers are only used for printed circuit boaeds, plated contact wires and noncritical connector parts.

10 Page 10 of 42 Company Organisation Plan for Telebox Industries Corp.

11 Page 11 of 42 Telebox Industries Corp. has one main plated contact and one main printed wiring board supplier. Telebox Industries Corp. has close cooperation with this printed circuit supplier for continuous improvement of quality. Incoming inspection and approval of printed wiring boards includes dimensional measurements and testing of hole diameters. Furthermore one sample is mounted with components, soldered and measured in permanent link with Fluke DTX 1800 field tester. The printed wiring board delivery is approved after passing of visual, dimensional and electrical requirements. Internally produced, pressure moulded and stamped components, are also included in the incoming inspection system. Some pressure moulded parts are delivered from external suppliers. Adhesion of contact platings is verified for each batch by bending of contacts and inspection for flaking of platings. Traceability of incoming components is possible by the order number. A first-in /first-out principle applies at Telebox Industries Corp. 5.3 Production Facilities All production of connecting hardware is carried out at the Hsichih factory of Telebox Industries Corp. Before production, the production leader verifies that all components and materials are available for the complete production process. Daily reports of rejection rate and failures are made for each internal production test step. Pressure moulding of plastic parts and stamping of metallic parts are applied at Telebox Industries Corp. Dimensional measurements and visual control are carried by the operator on samples from the running production. Telebox Industries Corp. has manual and automatic assembly lines for keystone jacks and patch panels. A sequence of mounting, soldering and visual inspection of each individual type of contact and connector part is applied. Operator training, and detailed, illustrated instruction guides are applied for each production process. dc resistance testing of each port of all finished connectors is applied. Keystone jacks are generally produced using hand mounting and automatic press-fit mounting of RJ 45 and ID contacts. Patch panels are produced using hand mounting of components, wave soldering of contacts at 275 C and hand soldering of screen contacts. A lead free soldering process is applied. A 100 % control for visual appearance, for shorts and for interupted connections is carried out after the assembly operation.

12 Page 12 of Final Testing All 3P qualified connectors have performance verified using re-embedded technology. Evaluation of internal testing data demonstrated generally fine performance. Any failing components are offered to the customer with documented performance data. Results of testing are stored in paper form together with the tested sample. Comparative re-embedded measurements at Telebox Industries Corp. and 3P of a specific Cat. 6 keystone jack have earlier been carried out for return loss, and in connection with the present inspection visit for forward and remote near end crosstalk. The measurements showed fine correlation between 3P and Telebox Industries Corp. for both return loss and near end crosstalk. The below sampling data for final testing at Telebox Industries Corp. applies, i.e. one sample from each new PCB delivery and one sample from each produced lot.
