Model 51200-S Dial-Up Test System

The Model 51200-S Dial-Up Test System thoroughly measures and verifies the operation of a broad range of modern telephony features, including Custom Local Area Signaling Services (CLASS), modem and FAX data-transport capability, POTS and coin telephone operation. The System is a compact, C.O.-based unit which responds to commands from the technician in the field with no assistance from other personnel.

The 51200-s incorporates unique features, such as EXPRESS TEST, single-person operation, Interactive Voice Response (IVR), and menu-selectable tests with programmable parameters and options, all designed to provide maximum testing speed and efficiency while reducing maintenance costs.

The System's IVR clearly introduces the test menu, prompts the technician through each test sequence, and reports test results. This IVR feature, coupled with EXPRESS TEST, makes the 51200-S the fastest, most easy-to-use and most complete test set of its kind.
