What is OMCI in GPON?
OMCI, short for ONT Management Control Interface, is a vital component to the operation of GPON (Gigabit Passive Optical Network). OMCI allows service providers to create a variety of applications and services utilizing the PON (Passive Optical Network), including voice, video and data, and features inherent flexibility.
In response to the surge in demand for high bandwidth from enterprises as well as residential customers, GPON has emerged as the most economical fiber option. 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). GPON supports triple play: voice, video, and data services.
Here is a diagram showing a GPON system with 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.
Some configurations needed to configure the service: such as custom ONU-type, vlan-profile, VOIP-profile, etc.

Note: After tcont1 and gemport1 and gemport2 are configured above, the corresponding TcontID and GemportID parameter information cannot be received on the ONU; that is to say, the OLT is not sent to the ONU in the form of OMCI; it needs to be in pon-onu-mng gpon- After onu_1/15/1:22 has configured the service-related configuration, it will be delivered to the ONU immediately.
The configuration is as follows: At this time, manually configure the WAN connection on the ONU WEB interface, and the service is communicating normally.
ZXAN(gpon-onu-mng)#show onu running config gpon-onu_1/15/1:22 pon-onu-mng gpon-onu_1/15/1:22 service 1 type internet iphost 1 gemport 1 vlan 100 service 2 type voip iphost 2 gemport 2 vlan 200
- Distribute VOIP and tr069 page parameter configuration through OMCI
The following is the WAN connection operation issued with the VOIP keyword:
ZXAN(gpon-onu-mng)#show onu running config gpon-onu_1/15/1:22 pon-onu-mng gpon-onu_1/15/1:22 service 1 type internet iphost 1 gemport 1 vlan 100 service 2 type voip iphost 2 gemport 2 vlan 200
The following mainly configure SIP server and SIP authentication account and password
The SIP server IP address or URL address is defined in the VOIP-profile template: note the at the end: portID does not need to be carried
The sip-service must be delivered in the form of a template, otherwise there will be a problem that the pots_0/2 voice account cannot be configured
voip protocol sip voip-ip mode dhcp vlan-profile v200 host 2 #OMCI issues VOIP WAN connection sip-service pots_0/1 profile VOIP userid 1 username 11111 password 11111 display-name 11111 sip-service pots_0/2 profile VOIP userid 2 username 22222 password 22222 display-name 22222
Tr069 The parameter configuration indicates the export business VLAN by way of business VLANID
Note that tr069 does not configure the user name and password for access: it needs to be pre-configured and set at the factory; C300 OLT can only be configured to issue the URL address parameters of TR069 ACS;
tr069-mgmt 1 state unlock (The default is the lock state. The ACS needs an account and password to access the CPE to be able to authenticate successfully. If you set unlock, you do not need an account and password to authenticate successfully. The premise is that the ACS server is configured with no account and password. Account password authentication registration method)
