ONT Management Via TR069+OMCI solution
GPON terminals are managed using one of these protocols: optical network terminal management and control interface (OMCI), Extensible Markup Language (XML), or Technical Report 069 (TR069). This article will introduce you ONT Management Via TR069+OMCI solution.
Optical network terminals (ONTs) are classified into three types: bridge type, bridge+voice type, and gateway type.
A bridge-type ONT provides Layer 2 data and multicast services.
A bridge+voice-type ONT provides Layer 2 data, Layer 2 multicast services, and voice over IP (VoIP) services.
A gateway-type ONT provides Layer 3 data, Layer 3 multicast services, and VoIP services.
Each different type of terminal management protocol has a unique service management scope. Based on terminal types, provides three GPON terminal management solutions: OMCI, OMCI+XML, and OMCI+TR069.
General principles of the OMCI+TR069 solution
This solution allows the U2000 to manage the OLT using SNMP, manage voice and Layer 3 services using TR069, and manage PON link layer using OMCI.
The OSS issues service configuration parameters to the U2000 using the TL1 NBI.
The U2000 manages the OLT using SNMP.
The OLT issues PON link layer configuration to the ONT using OMCI.
The ONT returns execution results to the OLT. Then the IP channel is set up.
The ONT registers with the ACS.
The ACS encapsulates user information in a TR069-compliant format and sends it to the ONT through the IP channel. The user information includes operations, maintenance items, and queries performed by a user. The IP channel is bidirectional.
OMCI+TR069 advantage:
An OLT version and an ONT version are not bound to each other. In other words, an OLT upgrade does not require an ONT upgrade; the opposite is also true.
TR069 provides an enhanced definition and deployment scenario for the IP-based customer premises equipment (CPE) service management model. Therefore, ONT vendors can easily deploy new gateway and voice services.
OMCI+TR069 disadvantage:
TR069 is based on the IP protocol and requires an extra IP management network.
Different interfaces are used to manage the ONT. The network management system (NMS) manages the link layer and the ACS manages IP-based services.
