About the Network

GT&T's Frame Relay Network is installed parallel to the Public Switch Telephone Network (PSTN) specifically to carry high-speed data traffic between two or more locations. This was done because of the demands of our customers to establish data links between their various locations, and the high cost of conventional point to point networks. It is made up of Nortel Networks Passport Switches inter-linked by fibre optic cables and E1 Circuits. Frame Relay is available in most of the towns and all the major business centres in Guyana. Traffic on the network is carried over Permanent Virtual Circuits and can support speeds of up to 155Mbps.

Benefits of using GT&T Frame Relay

1. It reduces your networking cost.
Reduced access and connection cost show immediate savings. The cost and benefits of connecting to our network is less than connecting your network by point to point methods of a similar speed and quality. In your current network configuration, linking all your sites would require multiple physical connections at each location. With our network we provide this same capability with one single physical connection at each location including Head Office.

2. Improves performance and availability of your network.
The network is supported by fibre optic cables that are known for their reliability, speed and security as a communications medium. As a result the performance of your network will improve as compared to the wireless modems which are subject to interference from the weather, vegetation, radio frequencies and tall buildings.

3. Simplifies your network management.
As the service provider, GT&T is responsible for keeping the network up 24 hours a day, hence reducing your work to the minimum. The network is managed by us at no extra cost to you.

4. You can take advantage of frame relay's bandwidth flexibility.

Bandwidth is dynamically allocated allowing for bursting over the purchase rate. Peak traffic hours are still handled by the network "for free." This is unlike lease lines and wireless systems where the bandwidth is fixed and you must plan and purchase bandwidth for the maximum traffic load.

5. Voice Over Frame Relay is one of the benefits of using frame relay networks.
6. Multi-protocol support including full TCP/IP support.
7. Changes to your network topology can be made without a visit to your premises.
8. Fibre provides secure, error-free and fast transmission of your data.
