Note
It is best to hold the cable just below the RJ-12 plug. This makes it easier to insert the plug
than if you hold the RJ-12 plug itself. When inserting it, make sure that you can hear the RJ-
12 connector click into place!
The following table shows the pinout of the two connectors for the above standard
connecting cable.
