Introduction MN-SLM5650AMN-SLM5650A
1–7
• (Static) Bridge Mode – This mode is used when the NP Interface is configured to
support a static point-to-point connection.
• Router Mode – This mode is used when the NP Interface is configured to support multi-
port Ethernet and, for Dynamic Point-to-Point Mode, to provide bridged connectivity for
data traffic while supporting routed network management and Vipersat traffic.
• BPM (Bridge Point-to-Multipoint) Mode – This mode is used when the NP Interface is
configured to provide bridged connectivity for data traffic while supporting routed
network management and Vipersat traffic.
Detailed information about these configurations and modes, and their functional association with
the Base Modem, NP Interface and/or the TRANSEC Module Interface, is provided in the
following chapters in this manual:

1.3.3.3 Data Interfaces
The SLM-5650A supports only one data interface at a time. The modem features two native data
interfaces (TIA/EIA-530/422 and TIA/EIA-613 [HSSI]), plus an option slot for installation of a
modular data interface. The optional modular interfaces available at this time are the Network
Processor, Gigabit Ethernet, G.703, and LVDS.
1.3.3.3.1 Network Processor
The optional Network Processor (NP) Interface is Comtech EF Data’s third generation IP router,
Ethernet bridge, and BPM (Bridge Point-to-Multipoint) device. The interface is designed to
process more than 150,000 packets per second (pps) in Layer 2, Layer 3, or Brouter mode of
operation. The NP Interface supports the following operating modes:
• Layer 2 Ethernet Bridge Mode
• Layer 2 and Layer 3 SCPC Ethernet Brouter Mode
• Layer 2 and Layer 3 Vipersat Brouter Mode
• Layer 3 SCPC IP Router Mode
• Layer 3 Vipersat STDMA Router Mode
• Extended Temperature Range -32 ° to 50 ° C
1.3.3.3.2 10/100/1000 BaseT (Gigabit Ethernet)
The optional 10/100/1000 BaseT (Gigabit Ethernet, or GbE) interface performs a simple bridge
function and passes IP packets, unaltered, in each direction between the LAN (10/100/1000
BaseT interface) and WAN (SLM-5650A modulator/demodulator).
