ADC T1544-30B T1 Short Loop Office Repeater
ADC telecommunications model T1544-30B Short Loop Office Repeater with the original box. This measures about 10" x 3.75" x .5" and is marked with "Date 940930" and a bar code "T1R1AL34AC". This is from the estate of an industrial telecommunications engineer and ham radio enthusiast. We don't know much about it, but is doesn't appear to have ever been used. A manual appears to be available on line from the manufacturer. We have not tested it.
