Chapter 6. Configuration61200051L1-1D ISU 2x64 Dual Port ISDN Service Unit User Manual 55Setting Protocol OptionsThe ISU 2x64 communicates with many different types of tele-communication equipment including other ISU 2x64s, ISDN ter-minal adapters, Switched 56 DSUs, and BONDING-compatibleinverse multiplexers. Communicating between such diversetypes of equipment requires various rate adaptation protocols tosupport various bit rates and DTE settings. See Figure 6-21 forthe menu tree. The ISU 2x64 supports the following rate adapta-tion protocols:• Clear Channel (no rate adaptation protocol) (synch. only)• BONDING mode 1 (Bandwidth on Demand InteroperabilityGroup)• CCITT V.120• CCITT V.110• DSU 57.6 ASYNC• T-LINK (Dial DDS DSU/CSU)• SAP (Simple ADTRAN Protocol)• FALLBACK• PPP async-syncFigure 6-21Protocol Menu TreeSee Recommended Operating Protocols on page 6 for more informa-tion on recommended modes of operation.The desired protocol may be selected with AT commands at theDTE port or from the ISU 2x64 front panel.
