In the upstream direction, the HG8240 is connected to the optical splitter and the network-

side OLT through the passive optical network (PON) port, namely the OPTICAL port, to

provide integrated access services.

l

In the downstream direction, the HG8240 is connected to various terminals through the

following LAN-side ports to implement the triple play service:

–

Four 10/100/1000M Base-T Ethernet ports, which can be connected to terminals such

as PCs, STBs, and video phoned to provide the high-speed data and video services.

–

Two TEL ports, which can be connected to telephone sets or fax machines to provide

superior and cost-effective voice over IP (VoIP), fax over IP (FoIP), and modem over

IP (MoIP) services.

3.1 OMCI Protocol

This topic describes the principles of the OMCI protocol and how to set up an OMCI channel.

3.1.1 Principles of the OMCI Protocol

This topic describes the principles of the OMCI protocol.

3.1.2 Setting Up an OMCI Channel

This topic describes how to set up an OMCI channel.

3.1.1 Principles of the OMCI Protocol

This topic describes the principles of the OMCI protocol.

The optical network termination management and control interface (OMCI) protocol is defined

in ITU-T Recommendation G.984.4. OMCI defines the format and the mechanism of the

messages exchanged between the OLT and the ONT. OMCI also analyzes the service model of

the ONT at a finer grain and defines a series of management entities used for service description.

OMCI specifies the format of the messages exchanged between the OLT and the ONT and the

mechanisms of confirmation and retransmission. In this way, OMCI provides a logical channel

for communication. Enabled with OMCI, the OLT supports the management and configuration

of various types of ONTs, the offline configuration of ONTs, and the configuration recovery of

online ONTs. Based on this mechanism, the ONT need not save the configuration information

locally. This helps to provision services and maintain the terminal.

3.1.2 Setting Up an OMCI Channel

This topic describes how to set up an OMCI channel.

Context

The process of setting up an OMCI channel between the OLT and the ONT is performed

automatically and requires no manual operation.

Procedure

Step 1

After being powered on, the ONT interacts with the OLT through Physical Layer OAM

(PLOAM) messages to complete the registration.

Step 2

From the PLOAM messages, the OLT learns whether the ONT supports the OMCI protocol. If

the ONT supports the OMCI protocol, an OMCI channel is set up between the OLT and the

ONT.

Step 3

After the OMCI channel is set up, the OLT issues the configuration and management information

about the ONT to the ONT through the OMCI channel, and the ONT uploads its status and alarm

information to the OLT through the OMCI channel.

NOTE

l

The PLOAM protocol is defined in ITU-T Recommendation G.984.3 and is used for the operation,

maintenance, and management at the physical layer.

l

OMCI is a master-slave management protocol. The OLT functions as the master device and the ONT

as the slave device. The OLT controls multiple ONTs through the OMCI channel.
