Some of the optional ME attributes are made mandatory.

Some of the mandatory ME attributes are set with default values (thus avoiding the need to update/utilize the attribute).

OpenOMCI is applicable only for the ONUs.

OpenOMCI is based on the ITU-T G.988 standard and it is consistent with G.988 with respect to the mandatory ME (Managed Entity) attributes. ITU-T OMCI (ITU-T G.988) and OpenOMCI are the two well-known OMCI standards available (Verizon also released a standard for OMCI intended to be used in Verizon networks). It is necessary to protect the downstream data with security as every message is broadcasted to all downstream ONUs.

These keys are used to enhance data security by invoking the downstream encryption and password protection.

OMCI supports a mechanism that allows mutual authentication of OLT and ONU and subsequent secure communication of encryption keys.

Link layer, network layer, and application layer are monitored in Ethernet mode.

Encapsulated traffic is monitored in GEM mode.

AAL1, AAL2, AAL5, VC and VP are monitored in ATM mode.

The ONUs create entities on request from the OLT, and monitor the data traffic and history of different services as listed below: In addition to the failure reporting, the OMCI also supports test, measurement, and in-service monitoring. The OLT collects the alarm information in real time for monitoring and resolution purposes. The ONUs detect and report equipment, software, and interface failures using alarms to the OLT. The OMCI primitive data unit is 48 bytes in length and it is encapsulated in a GEM frame (with GEM header of 5 bytes).

вЂ“ The ONU uses the OMCC to update its status and alarms information to the OLT. вЂ“ The OLT uses the OMCC to invoke the control and the management operations of the ONU

The OLT learns the capability of ONU to support OMCI by using the PLOAM messages and establishes the OMCC>.

Zte Gpon Snmp Management registration#

The ONU Initiates and completes the registration process with the OLT using PLOAM (Physical Layer OAM).The procedure below explains the OMCC establishment. On successful boot-up and registration of the ONU with the OLT, the OLT sets a GEM Port-ID to the ONU, which will be used by the ONU to map OMCC traffic. Update the OLT with fault alarms, performance threshold, and MIB value changes.Monitor the alarms and inform system failures.Manage UNIs (User Network Interface) at the ONUs.Establish and release connections across ONUs.OMCI is used by the OLT to manage the ONUs in the following areas: A protocol-independent MIB (Management Information Block) is used for configuring the entity information and storing the management records. The traffic in the OMCC channel has the highest transmission priority. The OMCI protocol messages are carried over Onu Management and Control Channel (OMCC) and are encapsulated into the GEM (GPON Encapsulation Method) frames. OMCI (ONU Management Control Interface) defines a mechanism and message format that is used by the OLT to configure, manage, and monitor ONUs. As shown in the figure below, a GPON system consists of: an OLT (Optical Line Terminal) at the central office, an ONU/ONT (Optical Network Unit / Optical Network Terminal) at the customer premises, and an ODN (Optical Distribution Network) in between the OLT and ONU. GPON supports triple play: voice, video, and data services. GPON is a form of fiber optic access network that uses a single optical fiber and an unpowered (passive) optical splitter to serve point-to-multipoint fiber to the premises (enterprise and residential). In response to the surge in demand for high bandwidth from enterprises as well as residential customers, GPON (Gigabit Passive Optical Network) has emerged as the most economical fiber option.
