522 NT8D02 and NTDK16 Digital Line cards
Table 199
Digital line card-power required
Voltage
±5.0 V dc
+15.0 V dc
–15.0 V dc
The digital line card needs +15V DC over each loop at a maximum current
of 80 mA. It requires +15V, -15V, and +5V from the backplane. The line
feed interface can supply power to one loop of varying length up to 1070 m
(3500 ft) using 24 AWG wire with a maximum allowable AC signal loss of
15.5 dB at 256 kHz, and a maximum DC loop resistance of 210 ohms; 26
AWG wire is limited to 745 m (2450 ft).
The digital line card provides +15 V dc over each loop at a maximum current
of 80 mA. It requires +15 V, -15 V, and +5 V from the backplane. One
NT8D06 Peripheral Equipment Power Supply ac or NT6D40 Peripheral
Equipment Power Supply dc can supply power to a maximum of 16 digital
line cards.
