TS19 Portable Test Telephone Users Guide WXWarning A The case is designed to give rugged service and Good safety practices prohibit the connection of the TS19 and similar test sets to 117 volts AC commercial electrical power; should the TS19 be connected to commercial power, all warranties are voided. The TS19 Portable Test Telephone is not designed to meet the outside plant requirements of Bellcore Publication TR-TSY000344.
Keypad Controls and Indicators B HI Z/RING/TALK Switch: This three-position slide switch is labeled as HI Z for high impedance monitoring, RING for ringer and low impedance monitoring, and TALK for talk. • • • In the HI Z position, the TS19 is on hook with a high impedance coupling to the telephone line. This allows for telephone line monitoring without disrupting conversations, data or signaling. In the RING position, the TS19 is on hook with an electronic ringer connected to the telephone line.
TS19 Portable Test Telephone Users Guide C Ground Start Cord: This cord consists of two 2 conductors with alligator clips. In addition, the red (ring) conductor has a banana jack attached. This jack is located six inches below the Portable Test Telephone and is partially covered by the outer fabric of the cord. A separate cord is also included. This cord is 36 inches long with a banana plug on one end and an alligator clip on the other. Cord Number: P1980007.
Maintenance To locate a short circuit: Open one side of the telephone line and place the test set in the loop — one lead to each side of the opened line. On the CO side of the fault, a loud click will be heard. On the field side of the fault, no click will be heard. To locate an open circuit: Bridge the test set across the circuit line — one test lead on tip, the other on ring. Moving away from the CO, the fault is at the point where the loud click disappears.
