Figure E-1. Network Processor (NP) Interface Module
The optional SLM-5650A Network Processor (NP) Interface Module (Figure E-1), also referred to as
the “NP Interface” or the “card”, is Comtech EF Data’s third generation IP router and Ethernet
bridge device. The NP Interface supports a number of primary operating modes:
•
Layer 2 Ethernet Bridge Mode
•
Layer 2 and Layer 3 SCPC Ethernet BPM (Bridge Point-to-Multipoint) Mode
•
Layer 2 and Layer 3 Vipersat BPM Mode
•
Layer 3 SCPC IP Router Mode
•
Layer 3 Vipersat STDMA Router Mode
The NP Interface is designed to process more than 150,000 packets per second (pps) in Layer 2,
Layer 3, or BPM mode of operation. It provides four RJ-45 connectors for user data, wired as
described in Table E-1. The NP Interface also has a single RJ-11 console interface that is intended
only for factory-use initial interface configuration. The Maximum Ethernet Frame size for the
SLM-5650A is 1518 for all modes.
