SUMMARY

The discussion centers on the limitations of fax machine cords, specifically the RJ-11 (phone jack) cable. Users noted that while a 6 ft cord is recommended for optimal performance, a 5 ft cord successfully restored functionality to a broken fax machine. One participant shared an experience with a 70 ft cable that still allowed for internet connectivity and fax transmission, indicating that while longer cables may reduce signal quality, they do not entirely inhibit functionality.

PREREQUISITES
  • Understanding of RJ-11 (phone jack) cable specifications
  • Knowledge of fax machine operation and requirements
  • Familiarity with signal degradation in telecommunications
  • Basic troubleshooting skills for fax machines
NEXT STEPS
  • Research the maximum distance specifications for RJ-11 cables
  • Learn about fax machine troubleshooting techniques
  • Investigate the effects of cable length on signal quality
  • Explore alternatives to traditional faxing methods
USEFUL FOR

Individuals dealing with fax machine issues, telecommunications technicians, and anyone interested in understanding the impact of cable length on signal quality.

I had a broken fax machine, and we finally found the book, after a month of looking. It said not to use a longer than 6 ft cord... Why? We replaced our 20 ft. with a 5 ft., now it works... hmmm :confused:

Which "cord" are you referring to? If it's the RJ-11 (phonejack) one, the cord can only be so long, a maxiumum distance. I don't know the maxiumum distance of an RJ-11 cable, but I imagine it's rather low.

From experience I don't think it is anything as small as 5ft. I used to have a cable going around the house (about 70ft long if not longer) so I could use the internet from my room and it did a pretty good job and it worked sending faxes through my fax modem too.

Although the internet connection speed you get is actually lower the longer the cable you use, it doesn't stop you completely from having a connection.
