FCC Part 68, DOC CS-03, UL 1459, and CAN/CSA-22.2 No. 225-M90 are all system (i.e. connectors, power
supply, cabinet, etc.) requirements. Since the MT88E43 is a component and not a system, the application circuit
(Figure 11) has been designed to meet the CO Trunk interface requirements of FCC, DOC, UL, and CSA; thus
enabling the complete system to be approved by these standards bodies.
Products are designed in accordance with meeting the above requirements; however, full conformance to these
standards is dependent upon the application in which the MT88E43 is being used, and therefore, approvals are the
responsibility of the customer and Zarlink will not have tested the product to meet the above standards.
