Bob,
The item you refer to is called
a Ring Initialization tool.
Try calling IBM.
I searched Black Box, Google.com
and IBM's website and found nothing.
Someone at IBM has one though.
Call tech services and ask where you can order one.

Subject: RE: IBM 8228 MAU
Has anyone ever seen a schematic diagram for the "port resetting thingy" ?
I have a MAU that does not seem to work...
Perhaps all it needs is a "reset" with such a device...
Perhaps one could build such a device yourself...
Anyone????

The 8 ports on the 8228 are electro-mechanical.
The Ring-In, Ring-Out ports are not.
The thingy with the red light has a 9-volt battery in it.
It is used to reset the 8 ports.
Insert the thingy into the port until the light turns on then off (takes
only a couple
of seconds.
You need to do this to an 8228 any time you have not used it for awhile.
