Hello I have acquired a working (or suppose to) AT&T Integrated
Services Digital Network 2B1Q Installation and Maintenance Test Set,
it includes a AT-T ISDN 7506 unit (phone) and ITE-6674 tester, I have
been trying to find information on this unit so I can use it in my
home lab or at least see if it works for what I need.
Any help would be great.....
