Huawei the PWX secondary power supply board

To supply the Huawei the FA16 device PWX board pieces PV8 board ATI transform to the plate supporting cable --- the the Huawei of FA16 device PWX board pieces PV8 board ATI the board pieces supporting cable CC03PWX secondary power supply board functions and principles of: communication systems, the AC The DC called once the power supply, while the DC input transformation called secondary power supply to the DC output. PWX board's main functions are: (1) For the purposes of the chassis to provide ± 5V DC, 75V AC ringing current; (2) monitoring, alarm output; (3) power backup (DC supply). Board of H303PV8 board (V5 protocol processing and control board) Overview H303PV8 V5 protocol processing and control board, also known as narrow-band control board, complete control of the same box narrowband veneer, and provides the narrowband business uplink E1 interface, narrowband exchange of resources and work the clock. H303PV8 plate is usually used in pairs, two veneer in active and standby mode, dual network dual hot backup to ensure the safety and reliability of the system working. E1 interface main standby function, using two veneer, E1 interface doubling. Each H303PV8 board provides eight E1 interfaces the 8 this box TTL HW interface, 32 extended differential HW interface. Two H303PV8 board provides 16 E1 interfaces, 8 this box TTL HW, the 32 expansion Differential HW interface. H303PV4 board with H303PV8 board functionality and performance indicators are the same, the main difference is that H303PV4 only four E1 interfaces. By E1 interface, H303PV8 the butt or cascade and the local exchange (LE), OLT or ONU. External wiring: PV8 cable trunk cable-PV8 to the DDF-15.00m-75ohm-4E1-2.2mm-(SYFVZ75-1.2/0.25 * 8) - (DIN4X8)-HONET relay cable-PV8 to DDF-30.00m- 75ohm-4E1-2.2mm-(SYFVZ75-1.2/0.25 * 8) - the relay cable-PV8 (DIN4X8)-HONET to DDF-40.00m-75ohm-4E1-2.2mm-(SYFVZ75-1.2/0.25 * 8) - -PV8 of the (DIN4X8)-HONET trunk cable to the DDF-50.00m-75ohm-4E1-2.2mm-(SYFVZ75-1.2/0.25 * 8) - (DIN4X8)-HONET relay cable-PV8 to DDF-60.00m-75ohm. -4E1-2.2mm-(SYFVZ75-1.2/0.25 * 8) - (DIN4X8)-HONET E & M interface board (ATI board) Overview: H301ATI board (referred to as the ATI board) is E & M interface board, can provide 6-channel 2-wire E & M interface and the Road 2/4 wire audio interface. H301ATI board is compatible with the user-card slot. Main functions: H301ATI plate through the access network semi-permanent connection channels with connected peer H301ATI board H301ATI plate E, M signaling signal detection, when the the signaling signal changes when, occupied channel encoding the signaling is sent to the peer, detection received the end H301ATI board signaling encoded control the plate corresponding to the corresponding signal output interface, channel resources usual interface occupied. Thus completing the transparent transmission of H301ATI board signaling signal and voice channel signal. Each H301ATI board can provide 2/4 the line audio line and 1E1M of signaling line does not support 2E2M. When the E, M signaling line when not in use, the 2/4 wire audio cable can be used independently, transmission of audio signals. H301ATI board audio interface level software adjustable, 2/4 line set by hardware jumper combined with software setup is complete.
