Splice Detection Screens; Chronic Circuit Screen - ADTRAN 1181113L2 Installation And Maintenance Practice

HDSL New Enhanced Feature Overview HDSL2 for General Distribution Installation and Maintenance Practice
EEPROM Support
The results of the splice detector are stored to the Electronically Erasable Programmable
Read-Only Memory (EEPROM) on a daily basis at the same time the 24-hour PM registers are
stored to EEPROM. A total of 14 days splice detection history is retained. This history is read
from the EEPROM upon power up.
Event Support
An event log entry "Splice Detector Reset' is made any time the splice detector is reset. Also an
event log entry "Bad Splice Detected" is made on the first detection occurrence seen since the
last splice detection reset. This entry serves to alert the technician that a trouble has been
detected without filling up the event log.
Splice Detection Screens
Chronic Circuit Screen
The Chronic Circuit screen (Figure B-2) displays general information about circuits with bad
splices.
NOTE
Since this detector employs a very sensitive measurement, it is
imperative that all obvious troubles be cleared prior to relying on the
splice detection information for troubleshooting the circuit. This is
reflected by the following screen statement: "Wire pairs pass all
electrical tests and meet deployment guidelines."
