APPARATUS FOR VERIFYING SUBSCRIBER CARD OF DSLAM AND METHOD THEREFOR, PARTICULARLY CONCERNED WITH CONFIRMING PERFORMANCE OF DSLAM SUBSCRIBER CARD WITHOUT EXTRA MEASURING INSTRUMENT AND WITHOUT DIRECTLY CONNECTING MODEM OF SUBSCRIBER

摘要

Purpose a: device, it is used to verify a DSLAM and a kind of subscriber card of method is arranged to confirm that the performance of DSLAM (digital subscriber line access multiplexer) subscriber card not will use an additional measuring instrument and will not be directly connected to DSLAM reservation cards to the modem of a subscriber thus, reduces expense and passes through removal user's line connection. Construction: in modulation or after solution adjusting data subscriber's card DeMux or multiplex data. From a subscriber of external certificate plate (400) card with subscriber block connect with construct link and subscriber block modem as many, judgement based on ATM (asynchronous transfer mode) data subscriber block performance input simultaneously performance is set in advance, judge reference data. Subscriber's card witness plate (400) includes by the following; One input equipment (410) input/output signal. One ATM cell processing unit (412) multichannel and DeMux ATM data are transmitted from input equipment (410). One DSL (digital subscriber line) subscriber modems (500) adjustment has received data from ATM cell processing unit (412) demodulation ATM. One line coupling part (414) is by DSL user's modem (500) and a subscriber. One processor (418) controls link setting between DSL user's modem (500) and a DSL modems, and judges the performance of DSL modems, and the unit of reference data and input is judged based on performance. One processor-Hardware match unit (416) connects ATM cell processing unit (412), an xDSL subscribers modem and processor (418).
