■ Modular Cord Telephone Wiring 6-pin 4-core Approximately 3m Beige ・This is a wiring cord for telephones. It is not a LAN cable. ・It's a rare crossover (rollover) type, possibly from the ISDN era. (Confirmed with a LAN cable checker.) ・It should work without problems with general household telephones, but you may need to pay attention to the polarity with business phones, etc. (I'm not sure of the details...) Please consider this item, understanding that it is a used product. Thank you for viewing.
