AUXILLARY EQUIPMENT A13.1 High Voltage Protection Equipment A13.1.1 Exchange Access Lines and Private Line Services A. General 1. Company services provided on metallic facilities that extend into a high voltage environment (i.e., electrical power generating, switching and distributing locations) require high voltage protection as a condition of service. 2. High voltage protection is required when either of the following induced voltage conditions can be expected on the metallic facilities due to Ground Potential Rise (GPR) and/or induction caused by faults in a customer's electric power system as follows: a. 800 Volts RMS or greater. b. 1100 Volts peak - asymmetrical or greater. 3. Faults in the customer's system include but are not limited to high voltages and currents that result from ground faults, switching transients and lightning. 4. The high voltage protection is designed to isolate hazardous voltages. 5. The protection objectives on Company services and facilities at these locations are as follows: a. To minimize electrical hazards to personnel engaged in construction, operation, maintenance and use of telecommunications transmissions. b. To limit electrical damage on telecommunications equipment, cable and wire facilities. c. To provide service continuity and integrity of telecommunications transmissions. d. To standardize design of equipment utilized for provision of protection from a hardware implementation standpoint. Original Page 2 EAST ASCENSION TELEPHONE CO., INC.

AUXILLARY EQUIPMENT A13.1 High Voltage Protection Equipment (Cont’d) A13.1.1 Exchange Access Lines and Private Line Services (Cont’d) C. Responsibility of Customer (Cont’d) 4. D. E. The customer shall provide 115 volt AC power fused with a 20-amp breaker to the equipment location. Responsibility of the Company 1. The Company shall install, test and maintain equipment provided within a mutually agreed upon time frame initiated by customer. 2. It is expressly declared that metallic facilities are in continually decreasing supply, and the Company is not obligated to continue to make such facilities available. Metallic facilities are offered only when existing facilities and operating conditions permit. Protective Service Types 1. Type 1- 2W: This service consists of two wire basic telephone service including direct current supervision and/or signaling and voice frequency spectrum transmission (may also include data service on an analog modem basis). 2. Type 2 - 4W – Special Services: This service consists of four-wire voice frequency spectrum transmission only-dedicated service. 3. Other: (See Section “H.1.c.”) Original Page 5 EAST ASCENSION TELEPHONE CO., INC. Gonzales, Louisiana By: Issued: Daniel J.

AUXILLARY EQUIPMENT A13.1 High Voltage Protection Equipment (Cont’d) A13.1.1 Exchange Access Lines and Private Line Services (Cont’d) F. G. Service Performance Objective Classification 1. Interruptions or outages of telecommunications circuits serving electric power substations may occur for physical reasons such as cable damage due to extraordinarily heavy storm loading, a vehicle striking and breaking a utility pole, a cable cut, a lightning strike, or acts of God. Circuit failures caused by such events cannot be prevented and the Company expressly states that provision of the service provided in this section cannot preclude such service outages as may occur due to the above mentioned circumstances. 2. Interruptions or outages due to the effects (GPR and/or induction) of faults in the customer's power generating, transmission and/or distribution systems are minimized through the installation and maintenance of high voltage protection service which is designed to operate in a fault-produced electrical environment. 3. The equipment provided in accordance with this tariff is designed for continuous telecommunications operation during power fault condition in compliance with specifications in Section "B". If service other than this is required by customer, see Section "H.1.c.". Provision of High Voltage Protection Service 1. The Company shall provide any required high voltage protection at the customer's premises and at the Company's central offices at rates and charges in Section "H". The Company will inspect and verify the protection when service is established at new or existing customer locations, and at future times as deemed necessary during changes, rearrangements or maintenance. 2. The Company reserves the right to suspend any service without adequate high voltage protection until adequate protection is provided. Original Page 6 EAST ASCENSION TELEPHONE CO., INC.
