Configuring ADSL router for SLT PeoTV

When purchasing SLT (Sri Lanka Telecom) PeoTV connection, we are getting a  preconfigured ADSL router and STB. Generally, the router they provided is a 4-port, low-cost ADSL router. The unit which I received with my PeoTV connection is "PROLiNK H5004NK", and it is a decent quality 4-port ADSL router with a WiFi transceiver.

I used this router for one year, and the main issues I noticed with this router are its unnecessary resets during heavy network traffic and limit configuration options.

Due to the recent upgrade of my network, I replaced this router with the TP-Link W8961ND router. TP-Link W8961ND bundles with ADSL 2/2+ Modem, 300Mbps WiFi access point, and 4-port router.

TP-Link W8961ND Router

I purchased this router from a computer component seller and NOT from SLT. As usual, this router arrives with the default configuration, and I managed to configure it for SLT ADSL and PeoTV without any problems.

The firmware version of this router is version 3.0.0 (Build 170103).

To link PeoTV, I configure this router with the steps mentioned below:

1. Under Interface Setup > Internet:

Configure PVC0 virtual circuit with ADSL connection details, such as:

• Status: Active
• VPI: 8
• VCI: 35
• ISP: PPPoA/PPPoE
• Username: ADSL username provided by SLT.
• Password: ADSL password provided by SLT.
• Keep the rest of the parameters in the default configuration.

 2. Select PVC1 and configure it with the following parameters:

• Status: Active
• VPI: 8
• VCI: 36
• ISP: Bridge Mode

3. Now select remaining virtual circuits and set their status to "Deactivated".

4. Under Advance Setup > VLAN > Define VLAN Group:

• Activate VLAN index 1 with the following settings:

• ATM VCs: only port 1.
• Ethernet: only port 4.
• Wireless LAN: None

• If VLAN index 1 is properly configured it should appear in the VLAN group summary as follows: 

e4,p1

• Select VLAN index 2, and activate it as the inverse of VLAN 1, such as:

• ATM VCs: port 2 to 7 except port 1.
• Ethernet: port 1,2 and 3.
• Wireless LAN: on all available ports such as ports 1 and 4.

•  The group summary of this VLAN should appear similar to this:

e3,e2,e1,w1,w4,p0,p2,p3,p4,p5,p6,p7

VLAN configuration summary

5. Under Advance Setup > VLAN > Assign VLAN PVID for each Interface, set all the parameters as follows:

• Set all ATM VC ports to PVID 2 except port 1. PVID of the ATM VC port 1 should set to 1.
• Except port 4, all Ethernet Port PVIDs must set up 2. PVIDs of the Ethernet Port 4 should set to 1.
• Set all Wireless LAN BSSID and Guest Network PVIDs to 2.

PVID assignment

6. Under Access Management > ACL add following rules:

• Rule 1:
• Secure IP Address: 0.0.0.0 ~ 0.0.0.0
• Application: ALL
• Interface: LAN

• Rule 2:
• Secure IP Address: 222.165.185.1 ~ 222.165.185.6
• Application: WEB
• Interface: WAN

• Rule 3:
• Secure IP Address: 222.165.185.1 ~ 222.165.185.6
• Application: PING
• Interface: WAN

Access control listing summary

The most tricky part of this configuration is setting up CWMP configuration entries. To configure this remote management channel I have to find ACS credentials. Without setting up these CWMP configurations I got "Unable to establish connection" on my PeoTV STB.

After carefully observing a couple of SLT preconfigured routers I manage to extract ACS credentials from few routers. Due to firmware issues of some routers, we can easily extract the ACS password by staring at the source code of the configuration page.

Extract the ACS password from the router configuration page.

Based on my finding I configure my router with the following credentials:

• ACS URL: http://acs.slt.lk/
• Username: acs@slt
• Password: Acs#6754

• Connection path: /tr069
• Port: 7547
• Username: acs@slt
• Password: Acs#6754

Periodic informs are activated with 1800 seconds interval.

After setup the above parameters, I manage to get PeoTV stream on Port 4 of the router. Remaining 3 ports are available for general Ethernet routing.
