SNA Connectivity
If you are one of the more than 50,000 businesses in
the U.S. that use System Network Architecture (SNA)
on your network, Sprint
Frame RelaySM Service
can enhance your network performance. Sprint Frame Relay
assigns a high priority to SNA traffic to provide the
speed and reliability required to support your mission-critical
applications.
Whether you are considering a new installation or a
transition from a legacy system, Sprint can help you through all
steps of the process, including consultation, acquisition,
implementation, and management.
Traditionally, SNA networks have been connected with
private leased lines, but cost and performance advantages
are leading more people to a frame relay solution. Below
is a comparison of both services as they apply to SNA
connectivity.
