4.1.6 Operation Configuration
This page shows the running configuration of eMTA.
Label
Description
Network Access
Display the status of eMTA, denied means
currently no connectivity is established. Deny the
access to Internet. Allow means allow the access
to Internet.
Maximum Downstream Data
Rate
Display the maximum downstream data rate.
Maximum Upstream Data Rate
Display Maximum Upstream Data Rate
Maximum Upstream Channel
Burst
Display Maximum Upstream Channel Burst
Maximum Number of CPEs
Shows the maximum CPE that can be connected
at LAN side to access Internet at the same time.
Modem Capability
Displayed certain configuration, like PHS enabled.

4.1.7 Event Log
Label
Description
First Time
Display the time of the event.
Last Time
Display the last time of the event.
Priority
Event log severity.
Description
Detail of the event log.
Refresh
Refresh the log record.
Clear Log
Clear all of the logs.
During daily operation and trouble shooting, log is very useful. For example, you
can see “configuration file CVC validation Failure”, this indicates that eMTA failed to
validate the CONFIG file downloaded from MSO’s TFTP server, maybe caused by
error root key. Furthermore, event logs will be stored unless user clicks “clear log”
button. Power cycle reboot will not clear event logs.
