Output ImpedanceA:50Ω nominal with VSWR <1.5:1
TX IF Frequency Range: 950 MHz to 2150 MHz (L-Band)
TX IF Output. Signal Level: -72 dBm to -28dBm (l-Band) across
50Ω
TX IF Output Impedance: 50Ω nominal with a VSWR <1.5:1
Provides the Ethernet IP traffic interface for the Modem in NCW
mode.
Provides the Ethernet IP traffic interface for the Modem in NCW
mode.
Supports bi-directional transfer of digitized voice data between
the Modem and external security equipment when operating in
NCW mode.
A bi-directional, asynchronous interface that may be used to
control the Modem in the SCPC mode.
Provides bi-directional data transfer between the Modem and
external Baseband equipment when operation in the SCPC
mode.
Supports asynchronous exchange of control and status
information between the Modem and external Terminal
equipment. The Frame Strobe signal on this connector is
utilized by the Modem in stacking operations. This connector
also provides an interface for connecting to an external GPS
device.

External Frequency Reference input, 5/10 MHz, from 0.1V to
1.0V (-7 dBm to + dBm). 50Ω, VSWR <1.5:1
Accepts up to 48V direct current (DC) input to be multiplexed
onto the primary TX IF Interface for antenna power.
Operates with voltage from 90 -- 132 VAC (110 VAC nominal)
and 180 - 264 VAC (220 VAC nominal) and frequencies from
47Hz to 63Hz.
Connection point for a ground cable.
Provides access to the serial debug ports of each of the
internal processors
