EPON VoIP tasks at a glance

To configure basic EPON VoIP, perform the following tasks:

1.     Configuring the IAD module on an ONU

2.     Configuring the voice VLAN operation mode on an ONU

3.     Bringing up a VoIP port on an ONU

4.     (Optional.) Setting the heartbeat parameters for the voice service on an ONU

Configuring the IAD module on an ONU

About this task

The Integrated Access Device (IAD) module acts as the gateway of the VoIP or FoIP media. Under the control of the SIP server or the Media Gateway Controller (MGC), IAD converts the analog voice data to IP data, transmits the IP data over the IP network, and completes call exchange between the calling and called parties.

You can configure the IP address of the IAD module on an ONU remotely.

You can issue the following operations to the IAD module on an ONU.

·     cancel—Cancels the registration of the IAD module from the SIP registrar server or MGC.

·     re-register—Registers the IAD module with the SIP registrar or MGC.

·     reset—Restores the factory defaults to the IAD module.

Configuration procedure

4.     (Optional.) Issue an operation to the IAD module of the ONU.	iad operation { cancel | re-register | reset }	N/A

 

Configuring the voice VLAN operation mode on an ONU

About this task

The voice VLAN feature enables the device to transmit voice packets on an ONU in a dedicated VLAN. Use this feature to guarantee the transmission of voice packets when a network congestion occurs.

The device supports the following voice VLAN modes:

·     Transparent mode—The ONU directly sends voice packets to the OLT without tagging the packets. As a best practice, do not use this mode.

·     VLAN tagging mode—The ONU tags voice packets with a VLAN ID.

·     QinQ mode—The ONU tags voice packets with an inner VLAN ID and an outer VLAN ID. The outer VLAN ID is used as the voice VLAN in the network layer for the service provider to manage voice services in a centralized way.

Configuration procedure

To configure the voice VLAN operation mode on an ONU:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Enter interface view.	·     Enter ONU interface view. interface onu interface-number ·     Enter RONU interface view. interface ronu interface-number	N/A

Bringing up a VoIP port on an ONU

About this task

You can remotely bring up a VoIP port on an ONU from an OLT.

An ONU might identify physical VoIP ports as POTS or FXS interfaces. Support for POTS and FXS interfaces depends on ONU model.

Configuration procedure

2.     Enter interface view.	·     Enter ONU interface view. interface onu interface-number ·     Enter RONU interface view. interface ronu interface-number	N/A
3.     Bring up a VoIP port on the ONU.	undo voip-port port-number shutdown	By default, VoIP ports on an ONU are shut down.

 

Setting the heartbeat parameters for the voice service on an ONU

About this task

An ONU sends a keepalive message to the SIP server or MGC at the heartbeat cycle. If no reply message from the server or MGC is received after the specified heartbeat count, the ONU determines that the connection with the server is down.

Configuration procedure

To set the heartbeat parameters for the voice service on an ONU:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Enter interface view.	·     Enter ONU interface view. interface onu interface-number ·     Enter RONU interface view. interface ronu interface-number	N/A
3.     Set the heartbeat parameters for the voice service on the ONU.	voip heartbeat { cycle interval | count count }*	By default, the heartbeat cycle is 60 seconds and the heartbeat count is 3.

 

Configuring the negotiation and transmission modes for the fax and modem services on an ONU

About this task

An ONU supports the following negotiation modes for the fax and modem services:

·     Auto-Voice Band Data (auto-VBD) mode—The ONU automatically changes the codecs for the fax and modem services without negotiating with the SIP server or MGC.

·     Auto-negotiation mode—The ONU negotiates the codecs for the fax and modem services with the SIP server or MGC.

An ONU supports the following transmission modes for the fax and modem services:

·     T.38—Fax-dedicated transmission mode. The ONU encodes the fax signals into data and then sends the data to the peer device over an IP network. The peer fax machine decodes the data into fax signals upon receiving the data. This mode features in low bandwidth usage and high transmission efficiency.

·     Transparent—Pass-through transmission mode, also called T30 mode. The ONU directly sends the fax signals to the peer fax machine over a PSTN network. This mode features in simple implementation and low transmission latency. However, it might suffer from packet loss and network jitter.

Configuration procedure

To configure the negotiation and transmission modes for the fax and modem services on an ONU:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Enter interface view.	·     Enter ONU interface view. interface onu interface-number ·     Enter RONU interface view. interface ronu interface-number	N/A
3.     Configure the negotiation mode for the fax and modem services on the ONU.	voip fax-modem negotiation-mode { auto-vbd | negotiate }	By default, the auto-negotiation mode is used for the fax and modem services on an ONU.
4.     Configure the transmission mode for the fax and modem services on the ONU.	voip fax-modem transmission-mode { t38 | transparent }	By default, the transparent mode is used for the fax and modem services on an ONU.

Configuring SIP digit maps for an ONU

About this task

A digit map is a dial plane used to restrict outgoing calls that can be placed on an ONU. If the dialed number does not meet the requirements of a digit map, the call cannot be placed.

A digit map can include the following characters:

·     Digits 0 to 9.

·     DTMF signs—Pound sign (#), asterisk sign (*), A, B, C, and D. These are functional keys on telephones.

·     Wildcard character—X. It is used to match any digit.

·     Range characters—Includes left square bracket ([), right square bracket (]), and hyphen (-). For example, range [*#] indicates asterisk sign (*) or pound sign (#) and range [0-9] indicates any digit in the range of 0 to 9.

·     Position character—Dot (.). If a dot is included in a digit map, it indicates that the preceding digit appears one or more times.

·     Digit map delimiter—Vertical bar (|). A digit map can include multiple dial plans separated by the delimiter, for example, 1xxx|3xxx.

·     Timer—T, S, or L.

Restrictions and guidelines

The device issues the configured digit maps to ONUs. Support for digit maps depends on the ONU model. Interpretation of digit maps varies by ONU model.

To allow an ONU to place any call number, configure only one digit map [0-9*#]..

If you configure the content multiples times for the same digit map, the most recent configuration takes effect.

You can configure a maximum of 64 digit maps.

Configuration procedure

To configure SIP digit maps for an ONU:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Enter interface view.	·     Enter ONU interface view. interface onu interface-number ·     Enter RONU interface view. interface ronu interface-number	N/A
3.     Configure a digit map for the ONU.	voip digit-map map-name map-content	By default, no digit maps are configured for an ONU. Default digit maps exist on some ONUs. Calls can be directly placed on these ONUs and no digit maps are required to be configured. Support for default digit maps depends on ONU model.

 

Adding SIP users to an ONU

Restrictions and guidelines

The SIP users to be added to an ONU must use phone numbers as well as username and password that have already been registered with the SIP registrar server.
