Zhone Technologies Z-PLEX-10-24-DOC-SC manual Bert, Bes, Clk

Parameter reference Alphabetical Reference

Syntax: GET PMTOT:ALLTOT:x

BERT

Activates a bit error rate test (BERT) on a T1 line. The BER test sends a data pattern and measures the bit error rate on the selected time slot. Possible values are:

•OFF (default): terminates the BER test.

•QRSS (quasi-random signal source): activates the BER test and sends a QRSS pattern during the BER test.

•ALT10: sends a 10101010 pattern during the BER test.

•2047: sends a 2047 test pattern during the BER test.

Note that you cannot perform a BER test and a loopback test simultaneously.

Configuration group: T1CFG

Syntax: (GET/SET) T1CFG:BERT:X:(QRSS/ALT/2047/OFF)

BES

BES (bursty errored second): indicates the total number of seconds with more than one and fewer than 320 CRC-6 (ESF), BPV (D4/D-frame), or CRC-4 (E1) errors.

Configuration group: PMCUR, PMTOT, PMINT, FARPMCUR, FARPMTOT, FARPMINT

Syntax: GET (PMCUR, PMTOT, FARPMCUR, FARPMTOT):x

Syntax: GET (PMINT, FARPMINT):x:(0-95)

CLK

Specifies whether the data port clock is inverted. DTE clocking usually requires a Normal setting. If synchronization problems occur, specify the clock is inverted. Possible values are:

•NORMAL (default)

•INVERTED

Configuration group: DPCFG

Syntax: (GET/SET) DPCFG:CLK:1:(NORMAL/INVERTED)
