MODULAR ONU

Features：

Miniaturized, low-cost, flexible deployment, suitable for deployment in ONU access density is not high, small and medium sized networks;

Layer aggregation switching, support port VLAN, flexible QinQ, link aggregation for network operators to offer a variety of flexible options;

QOS support, hardware-based implementations DBA dynamic bandwidth allocation in the downstream direction can configure multiple priority scheduling queue, a fundamental guarantee for the high-priority services can be best guaranteed QOS.

Rich OAM functions, the system supports ONU auto-discovery, auto registration, support for single link automatic loopback testing capabilities to support port-based, protocol-based VLAN support IGMP Proxy, Snooping function, ACL packet filtering based on port, packet classification, port-based traffic control, traffic shaping and other rich operable and management features.

. Complete network management functions support centralized management of my company s integrated network management platform EMS software supports native command line management, SNMP management, support the band, band network management;

EMS network C / S architecture-based design, with a complete network management capabilities. Supports automatic network topology, manually topological modification, support for OLT, ONU software online upgrade;

Easy to install, easy to maintain, plug and play device is turned on to work properly, ONU automatically registered, no additional configuration; the device after the device deployed operational status monitoring and configuration operations necessary business through a remote management platform.

Failure Analysis：
1 Power Check the following items to help separate issues:
Check the ambient conditions, you can not let EPON access equipment from overheating. Confirm EPON access equipment into and out of the pores clean. Recall "General site requirements." EPON access equipment requires temperatures workplace is -40 ° -85 °
As EPON access equipment can not start, and the "PWR" light is off, check the power supply.
2 ports, cables, and connection failure
If the port can not LINK EPON access equipment on, check the connection cables are correct, the peer connection is normal;
As the system starts, but Console port does not work, make sure the Console port is configured as 9600 baud, 8 data bits, no parity check bits, 1 stop bit, no flow control.
