Hello from the Eighth Doctor
I just completed a search for the descriptions behind the RJ48 device,
using this search term in Google, RJ48C, RJ48S, RJ48X. It returned
about 20 such requests, and then they started to repeat.
I am not convinced that the search engine has a properly defined
method for searching for technical subjects.
I have here a device which when properly configured will become the
CPE for a leased line such as the T1 family. And I needed to find out
how the connecters for it were wired. Even though the exact pinouts
were given in my Leviton book on the subject of cabling.

pins 1 & 4, 2 & 5) towards network.
RJ-48S: 8 position modular jack. Pins 1-2 & 7-8
