Cisco ONS 15454 SDH Installation and Operations Guide, R3.3
May 2002
Chapter 8 SDH Performance Monitoring
Changing Thresholds
Figure 8-9 Threshold tab for setting threshold values (Example of a DS3i card)
Change the threshold if the default value does not satisfy your error monitoring needs. For example,
customers with a critical E1 installed for emergency phone calls must guarantee the best quality of
service on the line; therefore, they lower all thresholds so that the slightest error raises a TCA.
Note A TCA is not reported if 0 or a number exceeding the threshold range is entered as the threshold
value.
Note Under the Provisioning > Threshold tab, the E1 card has user-defined thresholds for the E1 receive
(Rx) path PMs. In the Threshold tab they are displayed as EB, BBE, ES, SES, UAS, ESR, SESR, and
BBER without the Rx prefix. No threshold settings are associated with the E1 transmit (Tx) path
PMs. Displayed in the Performance tab are the PM counts received for the E1 Rx path PMs. The
displayed E1 Tx path PM values are based on calculations performed by the card and therefore have
no TCAs that require provisioning.
