Both a central office (CO) POTS splitter and a remote (R) POTS splitter shall conform to them. E.4.1.1 ! ! Frequencies and Level of Voice-band Signal Signal frequency: 0.2- 4.0 kHz Signal level: maximum of+3 dBm The frequencies and level of the voice-band signal provided by the local switch (LS) are as follows. A signal of+36 dBm at 400 Hz may be used as a howler signal. E.4.1.2 External CO POTS Splitter Function The external CO POTS splitter may be located some distance form the ATU-C modem. To protect against DC faults, DC blocking capacitors should be included in the xDSL port of the POTS splitter. These capacitors configure parts of the input to the xDSL HPF function, so they must be included when the input impedance is calculated. If the POTS splitter function is included entirely within the modem, the capacitors should be included as part of the HPF function. E.4.1.3 ZHP Definition To facilitate testing of the POTS splitter independently of the actual modem or specific vendor, two ZHP’s are defined to allow proper termination of the xDSL port during voice band testing. The ZHP’s are valid only for voice band frequencies. They shall be as shown in Figure E-19. ZHP Remote end(ZHP-r) E.4.2 DC Characteristics This paragraph contains the DC specifications, such as the loop DC current, the ringing, the L1-to-L2 DC voltage, the loop DC resistance, the isolation resistance, the L1-to-L2 capacitance, and the capacitance to ground, and the methods for measuring them. All requirements included in 1. must be met in the presence of all POTS loop currents ranging from 0 to 130 mA. E.4.2.1 Loop DC Current The POTS splitter should ensure normal operation for loop DC currents ranging form 0 to 130 mA 462 Boston St - Topsfield, MA 01983 - Phone: 978-887-8050 - Fax: 978-887-5434 P/N: AD-8039J E.4.2.2 Ringing The POTS splitter should accept the following ringing signals. !
