Figure 3 shows the recommended configuration for remote maintenance
monitoring on option 81, which also applies to option 51C, 61C, and 81C. In
this configuration, a switch box is normally set to the SDI port to remotely
monitor general system operation. The CPSI ports can be accessed for
debugging and patch downloading (through your Nortel Networks
representative).
