LTP-X EasyMode description

EasyMode is a function set of LTP optical terminals. EasyMode is dedicated to fast GPON deployment according to realized service model. EasyMode allows providers to configure Triple Play services promptly.

...

• Acquaintance with GPON technology and ELTEX equipment;
• Fast testing of the main capabilities of the equipment;
• Automatic configuring of the equipment on a network.

Software and hardware requirements

The EasyMode is supported by the hardware of B and C revisions and by NTU terminals. EasyMode operation requires the firmware version not lower than:

Installation and connection

To get acquainted with device hardware, installation and connection methods, refer to LTP user manual on the website.

Connection to the terminal

Connection to LTP is possible either with a console cable or with an Ethernet cable to the GE port.

Console cable connection

For LTP rev.B, the RS-232 cable DB9(F) – DB9(F), which is included in the delivery package, is used. The port is located on the left side of the front panel, as shown in Figure 1.

Table 2 lists connectors, LEDs and controls located on the front panel of LTP rev.C/rev.D.

Table 2 — Description of the connectors, LEDs, and controls located on the front panel of LTP rev.C/rev.D

Connect the cable and configure the following connection parameters:

...

Default username and password: admin/password.

Connection via Telnet/SSH

Connect the Ethernet cable to any of the GE/ComboGE ports. By default, the IP address of the LTP management interface — 192.168.1.2/24. Configure an address 192.168.1.1 on your computer and subnet mask 255.255.255.0 as it shown in Figure 4.

...

Default username and password: admin/password.

Service model in EasyMode

The EasyMode includes a prepared configuration for the network, a diagram of which is shown in Figure 5.

...

• Internet service using IPoE technology. It is possible to add option 82 specified by you to DHCP packets.
• "VLAN on service" model. Subscribers of one service are in the same VLAN.
• User isolation. There is no connectivity between subscribers at the channel level.
• Dedicated multicast VLAN. Unicast services: IPTV (Video-On-Demand, VoD) are spaced from multicast traffic.
• Multicast traffic is available for all ports of subscriber terminal.

EasyMode enabling and configuration

EasyMode can be used with the values you specify or with default values.

Default configuration

Parameters to be applied by default:

To enable EasyMode with default values, you should execute the easy-mode command. After that, a warning will be displayed stating that the current configuration of the device will be lost.

...

After that, you can proceed to sections 6.3 and 7 of this manual.

Custom configuration

You can change the settings of the LTP management interface, service VLANs and parameters of DHCP option 82 using the Wizard. In addition, you can quickly add already connected subscriber terminals and after completing the configuration, get a network ready for operation.
To start working with Wizard, you need to execute the easy-mode wizard command. After that, a warning will be displayed stating that the current configuration of the device will be lost.

VLAN Configuration

Specify the VLANs you want to use for the services. VLAN data will be automatically registered tagged to all Ethernet ports, with the exception of VLANs for the built-in ACS server.
If all the default values are correct, you can refuse the change by responding N to the invitation to change. If the default value for a single service is correct, you can skip input by simply pressing <Enter>.
As an example, change the VLAN as follows:

...

Current VLAN configuration:
 ACS VLAN ID: 2
 Internet VLAN ID: 100
 VoIP VLAN ID: 200
 VoD VLAN ID: 300
 Multicast VLAN ID: 400
Do you want to change VLAN configuration? (y/N):   y
        Enter ACS service VLAN ID (leave blank for default) [2]:
        Enter Internet service VLAN ID (leave blank for default) [100]: 1001
        Enter VoIP service VLAN ID (leave blank for default) [200]: 1002
        Enter VoD service VLAN ID (leave blank for default) [300]: 1003
        Enter Multicast VLAN ID (leave blank for default) [400]: 3

Configuration of the LTP management interface

In the next section, you can change the access settings for LTP. If you are satisfied with the default value, reply N to the change prompt. If you are satisfied with the default value for a single parameter, you can skip input by simply pressing <Enter>.
As an example, change the management settings as follows:

...

In this case, you need to select a different IP subnet.

DHCP Relay Agent (option 82) configuration

The last configuration step — DHCP option 82 configuration for substitution into packets from subscribers. By default, option substitution is disabled. If option 82 is not used on your network, you can skip configuring it by answering N to the prompt to change.
When enabling option substitution, the following values of the Circuit-Id and Remote-Id suboptions are used:

...

Do you want to use option 82? (y/N):   y
Current configuration dhcp-ra overwrite-option 82:
 Circuit id: %HOSTNAME%-%PONSERIAL%-%VLAN0%
 Remote id: -
        Do you want to setup Option 82 format?
  (answer No for default option) (y/N):   y
        Enter Circuit ID (leave blank for empty option): %GPON-PORT%-%ONTID%
        Enter Remote ID (leave blank for empty option): %MNGIP%

Saving configuration

After applying the new configuration, the following message will be displayed.

Adding new ONTs

Automatic ONT activation configuration

In the simplified setup mode, the ONT auto-activation mode is enabled, and the required ONT configuration is applied automatically from the corresponding auto-activation template. These templates were created when EasyMode was enabled. For NTU-1, which are controlled using OMCI protocol only, the easy-ONT template is used. For all other ONTs, the easy-RG template is used.

...

Manual ONT activation

After enabling and configuring EasyMode, in order to add new connected ONTs into the configuration, you need to:

Configuration of VoIP on the ONT

Consider configuring ONT RG parameters using the internal ACS on the basis of VoIP settings. For more information about working with ACS, refer to the Eltex ACS User manual, which can be found at the link.
Configure for the ONT 454C545866000101 the number 101 with the secret password on the SIP server sip.test.pon. For this purpose, do the following:

1. Execute the acs command to operate with the built-in ACS server.

   Блок кода
   language xml
   LTP-4X# acs LTP-4X(acs)#

   
   

2. Switch to the ONT configuration mode and select the desired ONT by serial number using the ont and ont 454C545866000101 commands.

   Блок кода
   language xml
   LTP-4X(acs)#ont LTP-4X(acs-ont)#ont 454C545866000101 LTP-4X(acs-ont-sn='454C545866000101')#

   
   

3. Set private parameters for enabling the phone line, SIP server address, numbers and passwords.

4. Apply the changes with the commit command and reconfigure the ONT with the reconfigure command.

   Блок кода
   language xml
   LTP-4X(acs-ont-sn='454C545866000101')#commit LTP-4X(acs-ont-sn='454C545866000101')#reconfigure Ok LTP-4X(acs-ont-sn='454C545866000101')#

   
   

5. Exit the ACS mode using the exit command.

   Блок кода
   language xml
   LTP-4X(acs-ont-sn='454C545866000101')#exit LTP-4X(acs-ont)#exit LTP-4X(acs)#exit LTP-4X#

   
   

Using a predefined ONT configuration without EasyMode

If you are not satisfied with the proposed EasyMode service model, you can only use the predefined ONT configuration by configuring LTP by yourself, according to your needs.

...

LTP-4X# configure terminal
LTP-4X(config)# interface ont 2/2
LTP-4X(config)(if-ont-2/2)# no easy-mode
LTP-4X(config)(if-ont-2/2)# exit
LTP-4X(config)# exit
LTP-4X# commit
    Changes successfully commited (1 chunk)
LTP-4X# send omci restore interface ont 2/2
    [ONT2/2] was successfully restored to default config and rebooted
