The off-hook ac termination is selected from the following:
0000 = 600 Ω
0001 = 900 Ω
0010 = 270 Ω + (750 Ω || 150 nF) (TBR21) and 275 Ω + (780 Ω || 150 nF)
0011 = 220 Ω + (820 Ω || 120 nF) (Australia/New Zealand) and 220 Ω + (820 Ω || 115 nF)
(Slovakia/South Africa/Germany/Austria/Bulgaria)
0100 = 370 Ω + (620 Ω || 310 nF) (New Zealand #2/India)
0101 = 320 Ω + (1050 Ω || 230 nF) (England)
0110 = 370 Ω + (820 Ω || 110 nF)
0111 = 275 Ω + (780 Ω || 115 nF)
1000= 120 Ω + (820 Ω || 110 nF)
1001 = 350 Ω + (1000 Ω || 210 nF)
1010 = 0 Ω + (900 Ω || 30 nF)
1011 = 600 Ω + 2.16 µ F
1100 = 900 Ω + 1 µ F
1101 = 900 Ω + 2.16 µ F
1110 = 600 Ω + 1 µ F
1111 = Global impedance
Read returns zero.
