26 FSU 5622 ESP User Manual 61200.175L1-1
Chapter 4. Applications
Different roles can be assumed for each SDLC session. Discon-
nection starts the role determination procedure again.
In all cases, the FSU 5622 ESP is transparent to the XID (exchange
identification) negotiation between any two network devices.
The FSU 5622 ESP uses LLC protocol (mode 2) to transport
SDLC information frames. This protocol ensures a reliable link
across frame relay, providing protection from frame loss and
excessive delays. The encapsulation method uses the RFC 1490
format. See Table 4-A for an example of how to configure the
FSU 5622 ESP for this application.
