Relay |
AT&T BusinessSM Frame
Relay Service offers you an affordable yet
fast and flexible data transport option.
Frame Relay is a connection-oriented
packet mode service that enables you to
transmit data at high speeds while
achieving cost-efficiency and performance
advantages over other architectures.
- Provides a fast, reliable alternative
to dedicated lines
- Makes it easy to add or
delete locations and modify
sites
- Allows you to create your
own routes and set up
permanent virtual circuits-your own
series of point-to-point virtual
connections-throughout your network
- Provides better performance
because it is based on X.25 LAPS
standards yet doesn't require the
error correction and control
information overhead of the X.25
protocol
- Establishes a "nailed-up"
connection between two locations in
the network, allowing large
variable-length frames to be sent back
and forth with very little control
information and validation at
intermediate nodes
- Includes 24x7
network monitoring and
maintenance
- Uses existing equipment
