2.1
Frame relay
The frame relay Speed Touch 591s provides the following key features:
•
support for SHDSL payload rates of 192, 384, 512, 768, 1024, 1152, 1536, 2048,
and 2304 kb/s
•
frame relay UNI, PVC support
•
frame relay QoS, providing four service categories:

•
•
•
•
frame-relay-to-ATM network interworking, allowing two frame relay devices to
be connected over an ATM network with guaranteed quality of service over the
entire line (see Figure 2-1)
•
frame-relay-to-ATM service interworking, allowing a frame relay device to be
connected to an ATM device over an ATM network (see Figure 2-2)
•
frame forwarding, allowing the system to support packet-oriented protocols such
as X.25 and PPP, which use HDLC-based packets, and to transport them across
an ATM network (see Figure 2-3)
