28.1.1 FR Configuration
A LR1104A LR1104A at Site 1 provides Frame Relay switching between a HSSI interface, connecting to the local router, and a 4 x T1 MFR bundle, connecting to the LR1104A. Continuity of PVC 16 is maintained through the LR1104A LR1104A, though this is not required.
The HSSI connection between the router and the LR1104A is defined as type UNI. The LR1104A serves as Frame Relay DCE and the router as the Frame Relay DTE. Note that the Frame Relay (Layer 2) interface type is independent of, and not necessarily the same as, the HSSI (Layer 1) interface type.

The BlackBox serves as a Frame Relay switch, connecting PVCs 16 and 31 through to another Frame Switch via a Clear Channel
