If the 12 V wall-mount power supply is used, check the supply’s cable and the circuit breaker for the 120 V receptacle the supply is plugged into.35Network LOS351. Verify that the cable from the network demarcation is in NET modular jack on the bottom/end of the T1 CSU ACE.352. If all connections seem intact, the far end CSU ACE can be looped back (using a BERT test set to send the LB code, or using MANUAL LB at the other end) to isolate the problem to the far end customer premises or the network.353. If the problem persists after the LB has been activated, the problem appears to be within the network or the far end CSU ACE. In this case, notify the carrier.354. If the problem disappears after loop-up, then the cause must be at the far end customer premises.35Equipment LOS361. Verify that the cable from the CPE is in the CPE modular jack on the bottom/end of the CSU ACE.362. If all connections seem intact, use a BERT test set in the NET IN and NET OUT jacks to test the CPE.36Power On - Self Check Failure36EPROM Checksum Failure36Maintenance36Chapter 4 Specifications37Network and Customer Interface37Line37Data Rate37Signal Format37Output Amplitude37Network Connector Type37Customer Interface Connector Type37LED Indicators37PWR37SYNC37Net LOS37NET MAN LB37NET RMT LB38EQ LOS38EQ MAN LB38EQ RMT LB38Power38Local Power38Environmental38Temperature38Relative Humidity38Index39A39B39C39D39E39I39L39M39N39O39P39S39T39U40Tamanho: 500 KBPáginas: 40Language: EnglishAbrir o manual
