4.1.5 Upstream Burst

Label

Description

Modulation Type

QPSK/16QAM.

Differential Encoding

On/Off

Preamble Length

0-1024 (bits).

Fixed: 16 to 253 (assuming FEC on). Shortened: 16 to 253

(assuming FEC on)

Scrambler Seed

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.
