Performance Monitoring
The performance of the RDTU can be monitored using the Data Dump Mode. This requires an
RSIU, RSIS, PIOU or PIOUS PCB, an ASCII terminal (or PC) and, if monitoring RDTU
performance from a remote location, an IMDU or RMDS modem or Hayes compatible modem is
required.
The RDTU monitoring feature provides a printout (or CRT display) of RDTU detected T1 errors
as shown in
Figure 8-11 . There are no time parameters given with this error report so the time
between error count increments must be monitored manually. Basically the error count of any error
category should not increase within 24-hour periods (see
Table 8-2 on Page 8-19 ).
