  The 935AT is a multi-functional portable unit that features a powerful Next Generation Voice Test Suite. It offers a laboratory quality VF TIMS, a full-featured BERT, RS-232, and a host of other functions as standard equipment. The 935AT’s versatile signaling features enables it to simulate, test and monitor at almost any point in a hybrid network. It is equally at home at the IAD, IP phone, gateway, switchroom, PBX closet, customer or carrier DEMARC, in the lab, or on the production floor. Its ability to simulate and monitor both sides of a connection makes it an indispensable troubleshooting tool. Performs voice processing design verification Characterized & Test Echo Cancellers Troubleshoot and Quantify packet voice impairments.
