Chapter 1 The BPX Switch: Functional Overview
BPX Switch Operation
Network Interworking
Part A of Figure 1-4 shows typical Frame Relay to network interworking. In this example, a Frame Relay
connection is transported across an ATM network, and the interworking function is performed by both
ends of the ATM network.
These are typical configurations:
•
IGX switch Frame Relay (shelf/feeder) to IGX switch Frame Relay (either routing node or
shelf/feeder).
•
MGX 8200 series Frame Relay to MGX 8200 series Frame Relay.
•
MGX 8200 series Frame Relay to IGX switch Frame Relay (either routing node or shelf/feeder).
Part B of Figure 1-4 shows a form of network interworking where the interworking function is performed
by only one end of the ATM network, and the CPE connected to the other end of the network must itself
perform the appropriate service-specific convergence sublayer function.
These are sample configurations:
•
IGX switch Frame Relay (routing node, shelf, or feeder) to BPX switch or to MGX 8220 ATM port.
•
MGX 8200 series Frame Relay to BPX switch or MGX 8200 series ATM port.
Network Interworking is supported by the FRM, UFM-C, and UFM-U on the IGX switch, and the FRSM
on the MGX 8200 series. The Frame Relay Service Specific Convergence Sublayer (FR-SSCS) of AAL5
is used to provide protocol conversion and mapping.
