TISP4310T3BJ Overvoltage Protector
Description (Continued)
After a TIA-968-A Type A surge, the equipment can be faulty, provided that the fault mode causes the equipment to be unusable. There
are two wave shapes used: 10/160 for longitudinal surges and 10/560 for metallic surges. For modems with a TISP4310T3BJ connected
between the Ring and Tip wires (and without overvoltage protection to ground), the longitudinal 10/160 surge applied to both Ring and
Tip will not activate the TISP4310T3BJ, giving an operational pass. The metallic 10/560 surge is applied between Ring and Tip wires
and will operate the TISP4310T3BJ. As the TISP4310T3BJ has a current rating of 100 A 10/560, it will survive the TIA-968-A Type A 100
A 10/560 metallic surge, giving an operational pass.
After a TIA-968-A Type B surge, the equipment must be operational. The 9/720 wave shape is used for both longitudinal surges and
metallic surges. For modems with a TISP4310T3BJ connected between the Ring and Tip wires (and without overvoltage protection to
ground), the longitudinal 9/720 surge applied to both Ring and Tip will not activate the TISP4310T3BJ, giving an operational pass. The
metallic 9/720 surge is applied between Ring and Tip wires and will operate the TISP4310T3BJ. As the TISP4310T3BJ has a current
rating of 120 A 9/720, it will survive the TIA-968-A Type B 25 A 9/720 metallic surge, giving an operational pass.
The TIA-968-A B-type ringer has voltages of 56.5 V d.c. and up to 150 V rms a.c., giving a peak voltage of 269 V. The TISP4310T3BJ
will not clip the B-type ringing voltage, as it has a high impedance up to 269 V.
