This adapter allows you to connect an RJ11 telephone connector to an RJ45 connector. This adapter would typically be used in installations that only have RJ45 connectors, but where you want to use a telephone with an RJ11 connector. All four pins in the RJ11 connector are wired straight through to the four middle pins in the RJ45 connector.
This means that the connector is universal, and can also be used for ISDN, etc. This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 6250-00-109-1091, indicating validated use in U.S. government and defense logistics supply chains.
