RFL VF-16B RFL Electronics Inc.
January 17, 2007 3 (973) 334-3100
-40 dBm0: Greater than 31 dB
-45 dBm0: Greater than 25 dB
Nominal Impedance: 600 Ω standard
Crosstalk Coupling:
400 Hz : 49 dB
700 - 1100 Hz: 59 dB
1100 - 3000 Hz: 58 dB
3700 Hz: 49 dB
Tracking (gain deviation for a 1004-Hz input):
+3 to -37 dBm0: 0.5 dB maximum
-37 to -50 dBm0: 1.0 dB maximum
-50 to -60 dBm0: 2.0 dB maximum

VF-16B Power Consumption:
Both Channels On-Hook with one phone per channel (factory default settings):
160mA@5V, 35mA@15V
Both Channels Off-Hook with one phone per channel (factory default settings):
210mA@5V, 95mA@15V
Both Channels Ringing with one phone per channel (factory default settings):
157mA@5V, 110mA@15V
Note 1: When connected to multiple phones and/or set to non-default settings, the board can
draw up to a total of 255mA@5V, and 225mA per channel @15V.
Note 2: When determining the power capacity in any given IMUX 2000 shelf, the power
consumption of the VF-16B is based on both channels ringing one phone per circuit with an
REN=1. If multiple phones are interconnected on each channel, please consult the factory for
proper power consumption that could impact the channel card capacity.
MA-302 and MA-302A Power Consumption:
TBD
Signaling Format:
T1 systems: RBS (Robbed-Bit Signaling)
E1 systems: CAS (Channel Associated Signaling)
Nominal Off-Hook Detection Threshold: 4.75 kΩ
