HUAWEI SSN6GSCC OptiX OSN 7500 system control board

• Provides the 10M/100M Ethernet port, which is used for communicating with the NMS. The Ethernet port is accessed through the EOW.
• Provides the F&f interface, which is accessed through the AUX and is used to manage the COA.
• Provides one 64 kbit/s synchronous data port F1, which is accessed through the AUX.
• Provides the RS232 OAM interface, which is used for connecting a PC or workstation, and supports the remote maintenance by using a modem that uses the RS232 DCE interface. The OAM interface is accessed through the EOW.

Processes a maximum of 160 DCCs (D1-D3). In this manner, the link is provided for transmitting the NM information.

• Provides the RTC.
• Supports the high-precision clock synchronization feature, and complies with the IEEE 1588 V2 protocol. The N4GSCC receives the time information through interfaces S1-S4 of the EOW. The S1, S3 and ALMI4 interfaces receive the first channel of time information, and the S2, S4 and ALMI4 interfaces receive the second channel of time information.

• Supports service performance monitoring and collects information about performance events and alarms.
• Provides 16 alarm inputs and four alarm outputs through the AUX.
• Provides one 4-output alarm cascading port through the AUX.
• Controls the four cabinet indicators through the AUX.
• Supports intelligent fan speed control and manages the fan alarms.
• Supports simulation package loading and diffused loading.
• Supports the function of detecting whether a packet data board is in position.

• Reports the alarm indicating a fault in the power supply (the power supply and the backup power supply of the EOW), for the AUX/EOW board.
• Supports the monitoring of the -48 V or -60 V power supply.
• Supports the in-service check function for the PIU board and supports the failure check function for the lightning protection module of the PIU.

The N4GSCC and N6GSCC support the packet function.
