Telecommunications

A. ADSL (Asymmetric Digital Subscriber Line)

• ADSL is a new, high speed transmission technology that makes possible the transport of multimedia applications over existing twisted pair copper telephone lines at spectacular speeds. ADSL supplies three (3) separate frequency channels over the same phone line.
  
  It supports:



• Two-way transmission of analog voice (POTS)
• A downstream (toward the customer) digital broadband channel of up to 8 Mbps for data
• An upstream (toward the CO) digital channel of up to 640 Kbps.

B. FRAME RELAY SERVICE

• Provides high-speed virtual private network capable of supporting applications with large bandwidth requirements:



• Fast
• Low Cost
• Flexible
• Connection-oriented

C. ISDN (Integrated Services Digital Network):

• ISDN allows you to integrate voice, data and video flexibility. And we offer two types of ISDN scaled to match your needs.



• Basic Rate ISDN (BRI) has two channels (B channels) for carring voive, data or video, and a third channel (D channel) which carries the call set-up information and low-speed packet data. Each of the B channels are capable of speeds as high as 64Kbps.



• Primary Rate ISDN (PRI) utilzes the same technology, but combines 23 B channels with one D channel. In total, PRI service offers up to 1.54Mbps of bandwidth, the equivalent of a T-1 line.
