Term

MARGINS

Indicates the excess signal to noise ratio, at either the COT or RT, relative to a 10

Rate. mn is the current margin, cr is the minimum margin since last cleared, mx is the

maximum value since cleared, and N/A means Not Available. The normal range of a typical

margin is from 22 to 6 dB.

PULSE

Indicates the attenuation of the 2B1Q pulse from the distant end. PG-Flex operates with

ATTENUATION

pulse attenuations in excess of 30 dB. This value is related to the cable pair's 196-kHz loss.

The pulse attenuation is a more direct indication of the loop attenuation to the 2B1Q signal

than the 196-kHz loss. The normal range of pulse attenuation is from 1 to 32 dB

PPM

Indicates the relative offset of the crystal oscillator in the RT Line Unit from the COT Line

Unit's crystal oscillator. Any value between -64 and +64 is adequate. Values outside this

range indicate out of tolerance components or excessive temperature drift of critical

components.

HDSL 24 Hour

The number of 1-second intervals that contained at least one CRC error. This value is a

ES (Errored

running total of the last 24 hours.

Seconds)

HDSL 24 Hour

The number of seconds the HDSL loop was out of synchronization. This value is a running

UAS

total of the last 24 hours.
