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&apos;t know much about it, but is doesn&apos;t appear to have ever been used. A manual appears to be available on line from the manufacturer. We have not tested it.
