GVTCI currently provides ADSL, SDSL, and IDSL.

RADSL broadband (Rate adaptive digital subscriber line)
Allows broadband data services to be carried on conventional copper pair telephone cables, with the rate adapting to the line conditions. The capacity provided depends on the distance between the subscriber's premises and the local telephone exchange; RADSL broadband provides higher capacities for subscribers who are closer to the exchange, with lower rates for subscribers who are further away.

SDSL (Symmetrical Digital Subscriber Line)
SDSL is a symmetrical service, which means that information travels upstream and downstream at the same rate. It was designed for applications requiring high speeds in both directions. SDSL speeds begin at 192 Kbps and go as high as 1.1 Mbps. SDSL is well suited for business applications because of its symmetrical nature.

IDSL (ISDN DSL)
IDSL is essentially used to provide DSL service to customers who do not qualify for SDSL or ADSL. IDSL is capable of reaching customers who are up to 36,000 feet away from the telephone company Central Office. IDSL operates at a symmetrical speed of 128 Kbps.

ISDN
Integrated Services Digital Network and is a system of digital phone connections which allows voice and data to be transmitted simultaneously across the world using end-to-end digital connectivity. There are two basic types of ISDN service: Basic Rate Interface (BRI) and Primary Rate Interface (PRI). BRI is a basic service is intended to meet the needs of most individual users. PRI is intended for users with greater capacity requirements.

WIRELESS
Using the radio-frequency spectrum for transmitting and receiving voice, data and video signals for communications.
