2-4 Installation and Setup
Connecting the DTE
The ASM-60 DTE interface provides interface for input/output data, clock
reference and control signals between the modem and the DTE. The ASM-60 DTE
interface can be either HSSI interface module, terminating in SCSI 50 female
connector (see Table 2-2), or one of the Ethernet interface modules, described in
greater detail in Appendix A, Appendix B and Appendix C.
To connect the HSSI interface:
• Attach the HSSI cable, terminated by SCSI 50 male connector to the SCSI 50
socket on the rear panel of ASM-60.
