The ATS 2E is a full-featured audio test set in a portable, hand-held unit. The set facilitates the installation and maintenance of leased or dial-up circuits and equipment connected to the Public Switched Telephone Network (PSTN). Designed to comply with CCITT recommendations, the ATS 2E performs all basic analog transmission measurements plus Signal-to-Noise (S/N) ratio, background noise and impulse noise tests. Noise filters provide CCITT psophometric weighting. The ATS 2E has manual and auto-dial facilities (DTMF/MF/Pulse), "line hold", integral speaker and microphone. It can also function as a telephone handset on 2- and 4-wire circuits, with dial, hold, talk and listen capabilities.
