3.7.2.1 The Company's facilities and service may be used with or terminated in Customer-provided terminal equipment or Customer-provided communications systems. Such terminal equipment shall be furnished and maintained at the expense of the Customer, except as otherwise provided in this price list. The Customer is responsible for all costs at its premises, including Customer personnel, wiring, electrical power, and the like, incurred in the use of the Company's service.

3.7.2.2 When such terminal equipment is used, the equipment shall comply with the minimum protective criteria set forth below and shall not interfere with service furnished to other Customers. Additional protective equipment, if needed, shall be employed at the Customer's expense.

3.7.2.3 When service(s) using voice grade facilities is terminated in Customer-provided terminal equipment, channel derivation devices, or communications systems, the Customer shall comply with the following minimum protective criteria:

a. When the facilities furnished under this price list are used in common with local telephone company services, it is necessary in order to prevent excessive noise and cross talk, that the power of the signal applied to the local lines be limited. A single valued limit for all application cannot be specified. Therefore, the power of the signal in the band over 300 hertz which may be applied by the Customer-provided equipment at the point of termination will be specified by the Company for each application, to be consistent with the signal power allowed on the telecommunications network as specified in FCC Part 68 Rules and Regulations.

b. To protect the telecommunications services from interference at frequencies which are above the band of service provided, the carrier will specify the acceptable signal power in the following bands to be applied by the Customer-provided equipment or communications system at the point of termination to insure that the input to facilities of the Company or other communications company that the Company connects with does not exceed the limits indicated.
