Network Protection 

Sophisticated Equipment Demands Sophisticated Protection 

• An unprotected or insufficiently protected communications network is a hazard to both your employee’s 

safety and your bottom line. 

• When a communications line is protected by Porta Systems products, hazards are quickly and safely shorted to 

ground. 

HAZARDS TO YOUR NETWORK 

Lightning: 

By far the most common cause of electrical surge damage to the communications network 

is lightning. Lightning can enter your network in a number of ways. It might strike a telephone 

or power line, causing high voltage to enter the equipment through incoming lines, 

or it might strike the ground and travel along buried cables. 

Power Crosses: 

Power crosses refer to incidents where a communications line comes in physical contact 

with an electrical power line. This could be caused by a downed telephone pole where 

phone and electrical lines have crossed. These incidents cause excessive AC current conditions 

to be carried into the communications system. 

Power Faults: 

Power faults should not to be confused with power crosses. In most buildings, the power 

company’s neutral line is bonded to the telephone company’s cable. If current is introduced 

onto this neutral line by any means, it can be transferred to the communications line and 

into the equipment. 

Induction: 

Communications lines need not come in direct physical contact with lightning or power 

overloads for a voltage spike or surge to be introduced on a line. These hazards can 

be induced from nearby sources such as the magnetic field surrounding a power line. 

Furthermore, when a brown out occurs, the power surge that accompanies the return to 

normal service can be transferred to nearby communications lines. 

Electrostatic Discharge: 

Most people have experienced the effects of electrostatic discharge in the home by simply 

walking across a carpet, touching a metal object and receiving a small shock. Similar type 

of shocks can be transmitted to communications circuits through the build-up and discharge 

of energy in dry climates.

Response of Various Transient Protectors 

Gas Discharge Tube (GDT) 

• A robust balanced three-electrode design. 

• Automatically resets after current surges of up to 10,000 Amps and high voltages. 

• Attractive for protecting high-speed carrier lines, such as T1, due to Ultra Low Capacitance. 

Solid State (S.S.) 

• Solid State thyristor based design. 

• Tighter voltage range which results in lower over-shoot voltage. 

• Quick transient response time. 

• Automatically resets after current surges of up to 100 Amps. 

Delta (GDT/TVS) 

• A robust balanced three-electrode GDT coordinated with Transient Voltage Suppressor 

(TVS) diodes. 

• Tighter voltage range which results in lower over-shoot voltage. 

• Quick transient response time. 

• Automatically resets after current surges of up to 20,000 Amps and high voltages.

primary voltage protection utilizing gas tube and solid state 

elements. Primary/Secondary voltage and current protection 

is provided by incorporating one or more of the following 

technologies into the protection circuit: 

• Gas Tubes 

• Thyristors 

• TVS Diodes 

• Metal Oxide Varistor (MOV) 

• Heat Coils 

• Heat Sensors

Gas Tube Protector 

(UL LISTED. HIGH ENERGY, 

ECONOMICAL, LOW CAPACITANCE) 

Provides a highly reliable and robust 

means of protecting equipment from 

high energy voltage and current surges 

(up to 10KA). The protector includes 

a heat-activated failsafe mechanism 

that provides protection against a 

sustained surge condition. 

Solid State Protector 

(UL LISTED. FAST RESPONSE, LOW 

ENERGY LET-THROUGH) 

With a response time of 5nanoseconds, 

these protectors 

are recommended for protection 

of sensitive equipment. An integral 

fail-safe mechanism permanently 

shorts the protector to ground in the 

presence of a sustained surge condition. 

Low Voltage Data 

Protectors 

(UL LISTED. HIGH-FREQUENCY DATA, 

ALARM, CCTV) 

For protection of LAN equipment 

and data communications circuits. 

Solid state technology provides fast 

reaction to hazardous voltage conditions 

and prevents damage to sensitive 

data equipment. For CAT 5E 

applications use our 505E or 1504PX2 

series blocks. (See page 19).

Building Entrance Terminals (BETs) 

In order to safeguard buildings and personnel 

from dangerous electrical surges, the 

National Electric Code (NEC) requires UL 

497 Primary Protection for incoming communication 

lines. This requirement applies 

to Service Providers (Telcos) at their demarcation 

point, and to Customer Premise owners 

and installers for runs between buildings in 

industrial, commercial, or campus environments. 

Failure to comply with this requirement 

not only creates a potentially dangerous 

condition, but also can result in costly fines, 

rework, and destruction of sensitive equipment. 

A Porta Systems Building Entrance 

Terminal (BET) equipped with its primary 

protectors meets or exceeds these 

demands.

SERIES 24 BETs 

Suitable for use by both Service Providers (Telcos) at 

their demarcation point and Customer Premise owners 

and installers for runs between buildings in an industrial, 

commercial, or campus environment.
