HDSL 3192 HTU-C Installation and Maintenance Practice6 61247004L1-5ARecommended maximum local loop loss information for PIC cable at 70°F, 135 Ω, resistivetermination is provided in Table 4.An approximation for the maximum amount of wideband noise on an HDSL local loop asmeasured by a 50 kbps filter is ≤ 31 dBrn.An approximation for the maximum level of impulse noise as measured using a 50 kbps filteron an HDSL loop is ≤ 50 dBrn.NOTEThese approximations are to be used as guidelines only and mayvary slightly on different loops. Adhering to the guidelines shouldproduce performance in excess of 10 -7 BER.Table 3.
