WHAT IS VSAT?WHAT IS VSAT?

A Very Small Aperture Terminal (VSAT) is a device – known as an earth station that is used to transmit and receive satellite transmission.

The VSAT dish antenna– that is mounted on a roof on a wall, or placed on the ground.

This antenna, along with the attached low-noise blocker or LNB (which receives satellite signals) and the transmitter (which sends signals) make up the VSAT outdoor unit (ODU), one of the components of a VSAT earth station.

The indoor unit (IDU) is a small desktop box that contains receiver and transmitter boards which used to communicate with user equipment – LANs, PCs or etc.

The indoor unit is connected to the outdoor unit with a pair of cables

FEATURES & BENEFITS Scalable, high-performance Internet Protocol (IP) system that

provides high bandwidth satellite forward and return channels.

The system offers broadband-on-demand IP multi-service access from a Cyberjaya & TPM Hub to remote locations with an asymmetric broadband multi-frequency TDMA return channel.

Enables broadband Internet access by leveraging the unique advantages of satellite-based networks in providing point-to-multi-point transmissions.

Guaranteed information rates for each network location

Lower-cost terminals because fewer hardware components are needed

IP ADDRESSING

32 Bits

10 121 194 193. . .

Every machine on the Internet has a unique identifying number, known as IP address. Each IP address is 32 bits long and is composed of four 8-bit fields, called octets. The octets are splits into two sections :

Network ID : Identifies the network that a computer belongs to.

Host ID : Identifies the actual computer on the network.

Note: Network IP address & Broadcast IP address are not being used

Subnet mask used is 255.255.255.192.

Therefore, the following are the IP Address block in used :

NIC CONFIGURATION

• Set the properties of the Internet Protocol (TCP/IP)• Change the IP address and DNS server addresses

IP address : 10.121.194.194 Subnet mask : 255.255.255.192 (fixed)Default gateway : 10.121.194.193

Preferred DNS server : 10.251.3.2 (fixedAlternate DNS server : 10.253.0.13 (fixed)

* Note : For VSAT – JaringPreferred DNS server : 161.142.2.17 (fixed)Alternate DNS server : 161.142.212.17 (fixed)

Domain Name Server (DNS) - The Domain Name System (DNS) is a distributed Internet directory service. DNS is used mostly to translate between domain names and IP addresses, and to control Internet email delivery. Most Internet services rely on DNS to work, and if DNS fails, web sites cannot be located and email delivery stalls.

VSAT FIRST LEVEL TROUBLESHOOTING

02/27/06

Problem Troubleshooting Suggestion PC cannot access the Internet

Use the ping utility to check whether your PC can communicate with the RCST Router LAN IP address. If it cannot, check the Ethernet cabling, and check the LED status.

Check the gateway IP Address on the computer is a valid IP address, if it is not, correct the address.

Verify with GITN the DNS server specified for the PC is valid.

PCs cannot display web pages on the Internet.

Verify that the DNS server specified on the PC’s is correct. You can use the ping utility to test connectivity.

Note: LAN or Gateway IP Address is an IP Address belonging to the RCST Router. DNS IP Addresses are 10.251.3.2 and 10.253.0.13.

VSAT FIRST LEVEL TROUBLESHOOTING

02/27/06

VSAT INDOOR UNIT

Firstly, when the RCST’s power source is on - all four LEDs (PWR, ALM, ODU, and SAT) will be turned ON for approximately 3 to 5 seconds indicating power-on for POST test.

After 3 to 5 seconds, the PWR and ODU LED should stay ON and SAT LED will then starts blinking slowly indicating receive of outbound carrier.

After 5 to 10 seconds, the SAT LED will be blinking quickly indicating inbound synchronization in progress and stays ON and GREEN during operational. (Refer to the diagram)

During normal operation, the PWR (power), ODU, and SAT LED should stay ON. If for some reason either one of these LED is not ON or blinking, please refer to Link Star trouble shooting guide (refer to the diagram).

What should you do when you see thispage ?

02/27/06

Do not panic and please follow this checklist.

Ensure the Router is ON. UTP cable is tightly connected to the

Router/IDU and PC. Telephone line is connected to the

Router/IDU. Correct IP address, default getaway and DNS

IP addresses inserted.

Next are the easy step by step procedures for basic troubleshooting Note: Same method can be used for Win 98

02/27/06

Step 1: Click START and move the cursor to RUN

02/27/06

Step 2: Type command and Command prompt (black screen) will appear

02/27/06

Step 3: Check your IP

Type Type ipconfigipconfig Example, IP of PC is 10.39.155.2Example, IP of PC is 10.39.155.2

02/27/06

Important Information to remember

IP Address = Current IP used (PC) Subnet Mask = 255.255.255.192 (fixed for all) Default Getaway = Router’s IP

02/27/06

Step 4: PING Command

The purposes for ping command are:

• Verify hardware connection

• Test IP Network connectivity

For SchoolNet, 2 steps of ping test

need to be conducted:

1) Ping ADSL Router IP Purpose : To check router

connection Example : ping 10.39.155.1 Refer Figure 1

2) Ping DNS IP addresses Purpose : To check Internet

browsing Refer Figure 2
