AT&T® DS1 Service
AT&T® DS1 Service provides cost-effective digital connections for businesses with heavy data traffic volume. Operating at 1.544 megabits per second (Mbps), DS1 Service lets you combine voice and data traffic, link remote hosts, and make your business more productive with data-intensive applications like video conferencing.
DS1 Service provides the equivalent of 24 voice-grade 64-Kbps channels, with 64-Kbps clear-channel end-to-end transmission. This means your interstate or international data transmissions can be carried by the long distance carrier of your choice, ensuring smooth handoffs. AT&T's digital network guarantees a performance objective of 99.995% error-free seconds. And with remote testing, AT&T can pinpoint the location of line trouble easily and fix it quickly.
Since DS1 Service carries your data traffic on dedicated circuits—not switched with the traffic of others—you'll enjoy unmatched data security. Dedicated service simplifies network management, too, since you won't have to keep track of different levels of switched network links.
As your data transmission needs grow, DS1 Service lets you migrate seamlessly to AT&T's higher-speed services, such as DS3 Services. What about options? Superframe and Extended Superframe formats are available. And AT&T Network Reconfiguration Services gives you complete control over your network by letting you reroute traffic as needed.

How It Works
In AT&T's Network
AT&T® DS1 Service uses dedicated private lines between sites that you designate. The service uses end-to-end digital facilities, which are inherently more reliable than analog. Why? An analog system converts your data, which is digital, to analog format, then amplifies the signal for transmission—also amplifying noise the signal encounters, increasing the chance for error. A digital system accepts your digital data without conversion, simply regenerating the original signal as it moves through the network. AT&T's digital network uses timing controls to ensure that signals conform to international standards, so your data can flow seamlessly to other carriers worldwide.
At Your Premises
Any piece of equipment linked to a DS1 Service facility must connect using a standard DS1-compatible channel/digital service unit (CSU/DSU) or CSU/DSU-capable device.
