Digitally controlled transmission impairment measuring apparatus |
| abstract |
A portable microprocessor controlled transmission impairment measuring unit capable of operating as a master unit or a slave unit and responsive to digital or manual control measures all basic parameters necessary to characterize a voice channel for its ability to transmit data traffic, as defined by Bell System Technical Reference PUB41009, dated May 1975. Measurements can be made manually end-to-end with a unit at each end of a circuit to be tested; manually looped-back with a unit at one end of the circuit; or remotely from one end with a MASTER operated unit controlling a SLAVE operated unit with all measurements displayed on the MASTER unit. The unit can also be used as a voice frequency repeater and can be operated with other test sets and computers having compatible measurements and capabilities. |
