Applications
When protecting telecommunication circuits,
P
devices are connected across Tip and Ring for metallic protection
and across Tip and Ground and Ring and Ground for longitudinal protection. They typically are placed behind some
type of current-limiting device. Common applications include:
• Central office line cards (SLICs)
• T-1/E-1, ISDN, and xDSL transmission equipment
• Customer Premises Equipment (CPE) such as phones, modems, and caller ID adjunct boxes
• PBXs, KSUs, and other switches
• Primary protection including main distribution frames, five-pin modules, building entrance equipment, and station
protection modules
• Data lines and security systems
• CATV line amplifiers and power inserters
• Sprinkler systems

P
solid state protection devices protect telecommunications equipment such as
modems, line cards, fax machines, and other CPE.
P
devices are used to enable equipment to meet various regulatory requirements including
GR 1089, ITU K.20, K.21 and K.45, IEC 60950, UL 60950, and TIA-968 (formerly known as FCC Part 68).

The Basic Characteristic of the P
The principle introduction
Operation
In the standby mode,
P
devices exhibit a high off-state impedance, eliminating excessive leakage currents
and appearing transparent to the circuits they protect. Upon application of a voltage exceeding the switching
voltage (V
S
),
P
devices crowbar and simulate a short circuit condition until the current flowing through the
device is either interrupted or drops below the
P
device’s holding current (I
reset and return to their high off-state impedance.

Once this occurs,
