Up to 128 ONTs per PON port can be connected to LTP-8(16)N. Up to 256 ONTs using XGS-PON technology or 128 ONTs using GPON technology can be connected to LTX-8(16), LTX-8(16) rev.B. Up to 256 ONTs using XGS-PON technology or 128 ONTs using GPON technology can be connected to LTX-8(16)C. On LTX-8(16)C, odd-numbered logical ports operate in GPON mode, while even-numbered ports operate in XGS-PON mode. This must be taken into account when configuring multiple ONTs, since it is not possible to set an ONT index higher than 128 for ports in GPON mode.

APPENDIX E. ONT SFP-ONU configuration

The LTX product line offers SFP-ONU solutions for both operating standards: NTU-SFP and NTX-SFP. Their configuration is identical, with the exception of selecting the port operating mode. Below are examples of SFP-ONU configurations with traffic passing in different modes: untagged, trunk mode, and tunnel mode.

When working with LTX, it is necessary to configure the PON port operating mode according to the used standard:

Enter the configuration mode:                                        
LTX-16# configure terminal

Go to the configuration of the PON port to which the NTU will be connected:
LTX-16(configure)# interface pon-port 1

Change its operating mode:
LTX-16(config)(if-pon-1)# pon-type gpon

Apply and save the configuration:	 
LTX-16(config)(if-pon-1)# do commit
LTX-16(config)(if-pon-1)# do save

After changing the port operating mode, the OLT will be reconfigured.

For correct operation in GPON mode, it is necessary to create a DBA profile with the recommended bandwidth settings:

Enter the configuration mode:                                                
LTX-16# configure terminal

Create a new DBA profile:
LTX-16(configure)# profile dba dbaGPON

Configure PON-type GPON:
LTX-16(config)(profile-dba-dbaGPON)# pon-type gpon

Set the recommended guaranteed bandwidth value:
LTX-16(config)(profile-dba-dbaGPON)# guaranteed bandwidth 512

Set the recommended maximum bandwidth value:
LTX-16(config)(profile-dba-dbaGPON)# maximum bandwidth 1244160

Apply and save the configuration:
LTX-16(config)(profile-dba-dbaGPON)# do commit
LTX-16(config)(profile-dba-dbaGPON)# do save

This profile will need to be used when configuring interface ont instead of the default dba1 profile.

Configuration example for VLAN transmission via an untagged ONT SFP-ONU

Task

Configure the terminal in bridge mode. Data transmission to the ONT will be carried out in VLAN 2149. Untagged traffic will be output from the SFP-ONU.

Solution

A distinctive feature of the ONT SFP-ONU is that it operates only in bridge mode. Full configuration is performed by the OLT using the OMCI protocol without the need for an ACS server.

Suppose the upstream switch is connected to front-port 1. Add the required VLAN to its configuration:

Enter the configuration mode:                                             
LTP-N# configure terminal

Uplink-port configuration mode: 					
LTP-N(configure)# interface front-port 1

Receive traffic in VLAN 2149 from front-port 1:					
LTP-N(config)(if-front-1)# vlan allow 2149

Apply configuration:
LTP-N(config)(if-front-1)# do commit

Configuration example for VLAN transmission via ONT SFP-ONU in Tunnel mode

Task

A tunnel needs to be established in VLAN 700 for client services: IPoE (VLAN 100), PPPoE (VLAN 200), and multicast (VLAN 300). The OLT uplink receives double tagged traffic with these services in a single external tag, which will be used for tunneling: 700.100, 700.200, 700.300. They need to be passed to the switch connected to the OLT via SFP-ONU.

Solution

Add tunnel VLAN to the uplink interface configuration:

Enter the configuration mode:												
LTP-N# configure 

Uplink-port configuration mode:                 
LTP-N(configure)# interface front-port 1

Receive traffic in VLAN 700 from front-port 1:		
LTP-N(config)(if-front-1)# vlan allow 700

Apply configuration:
LTP-N(config)(if-front-1)# do commit

Cross-Connect and Ports profiles configuration:

Create and enter the Cross-Connect profile for SFP-ONU:	 
LTP-N(configure)# profile cross-connect tunnel

Set a service architecture for 1-to-1:
LTP-N(config)(profile-cross-connect-tunnel)# traffic-model 1-to-1

Specify bridge mode operation:	             
LTP-N(config)(profile-cross-connect-tunnel)# ont-mode bridge 

Assign this Cross-connect to bridge group 20:	 
LTP-16N(config)(profile-cross-connect-tunnel)# bridge group 20

Specify Tunneling VLAN        
LTP-N(config)(profile-cross-connect-tunnel)# outer vid 700    

Enable multicast traffic passing
LTP-N(config)(profile-cross-connect-tunnel)# multicast enable

To ensure proper flow of multicast traffic, it is necessary to disable IGMP snooping in the tunneling VLAN. To ensure proper flow of IPoE and PPPoE traffic in the tunneling VLAN, it is necessary to disable DHCP and PPPoE snooping:

Enter the  VLAN tunneling configuration mode:
LTP-16(configure)# vlan 700

Disable igmp snooping:
LTP-N(config)(vlan-700)# no ip igmp snooping enable

Return to the top configuration section:
LTP-N(config)(vlan-700)# exit

Go to ip dhcp configuration:
LTP-N(configure)# ip dhcp

Disable dhcp snooping in VLAN tunneling:
LTP-N(config)(dhcp)# no snooping enable vlan 700

Return to the top configuration section:
LTP-N(config)(dhcp)# exit

Go to ip pppoe configuration:
LTP-N(configure)# ip pppoe

Disable PPPoE snooping:
LTP-N(config)(pppoe)# no snooping enable

Apply configuration:
LTP-N(config)(pppoe)# do commit

Save configuration:
LTP-N(config)(pppoe)# do save

Configuration example for VLAN transmission via ONT SFP-ONU in selective-tunnel mode

In addition to the previous settings, in tunnel mode it is needed to perform the following steps:

Change cross-connect operating mode to "selective-tunnel"
LTP-N(configure)# profile cross-connect tunnel
LTP-N(config)(profile-cross-connect-tunnel)# tag-mode selective-tunnel

Specify the needed VLAN ID for the previously configured ONT service:								
LTP-N(config)(if-ont-1/3)# service 1 selective-tunnel vid 100,200,300

Apply configuration:		
LTP-N(config)(if-ont-1/3)# do commit
