Connection of Customer-Provided Terminal Equipment to the 
Telephone Network

AGENCY: Federal Communications Commission.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: The FCC published in the Federal Register of November 19, 1997 
(62 FR 61649), final rules to Part 68 of Title 47, Code of Federal 
Regulations. Those rules govern the terms and conditions under which 
customer-provided terminal equipment may be connected to the telephone 
network without causing harm to the public switched network. This 
document corrects the typographical errors and omissions found in that 
document.

EFFECTIVE DATE: May 7, 1998.

    (e) Intentional paths to ground (as required by Sec. 68.304). (1) 
Connections with operational paths to ground. Registered terminal 
equipment and registered protective circuitry having an intentional dc 
conducting path to earth ground at operational voltages that was 
excluded during the leakage current test of Sec. 68.304 shall have a dc 
current source applied between the following points:
    (i) Telephone connections, including tip, ring, tip 1, ring 1, E&M 
leads and auxiliary leads, and
    (ii) Earth grounding connections.

    Note to paragraphs (e)(1)(i) and (e)(1)(ii): For each test 
point, gradually increase the current from zero to 1 ampere, then 
maintain the current for one minute. The voltage between paragraph 
(e)(1)(i) and paragraph (e)(1)(ii) of this section shall not exceed 
0.1 volt at any time. In the event there is a component or circuit 
in the path to ground, the requirement shall be met between the 
grounded side of the component or circuit and the earth grounding 
connection.

    (2) Connections with protection paths to ground. Registered 
terminal equipment and protective circuitry having an intentional dc 
conducting path to earth ground for protection purposes at the leakage 
current test voltage that was removed during the leakage current test 
of Sec. 68.304 shall, upon its replacement, have a 50 or 60 Hz voltage 
source applied between the following points:
    (i) Simplexed telephone connections, including tip and ring, tip 1 
and ring 1, E&M leads and auxiliary leads, and
    (ii) Earth grounding connections.

    Note to paragraphs (e)(2)(i) and (e)(2)(ii): Gradually increase 
the voltage from zero to 120 volts rms for registered terminal 
equipment, or 300 volts rms for protective circuitry, then maintain 
the voltage for one minute. The current between (e)(2)(i) and 
(e)(2)(ii) of this section shall not exceed 10 mA peak at any time. 
As an alternative to carrying out this test on the complete 
equipment or device, the test may be carried out separately on 
components, subassemblies, and simulated circuits, outside the unit, 
provided that the test results would be representative of the 
results of testing the complete unit.
