SLM-5650A Satellite Modem
Network Processor (NP) Interface
User access to management and control of the NP Interface via the built-in HTTP/HTTPS
Interface or Telnet server (port 23) is possible using the available RJ-45 connectors (see Figure
8-2) as follows:
• When in Router Mode, access is possible using any of the NP Interface RJ-45 Ports 1
through 4.
When in BPM Mode (see Chapter Sect. 8.5), only the base modem's J5 Ethernet RJ-
•
45 port can be used for management and control.

Functional Hardware Description

The NP Interface employs the very high performance Intel IXP2350 network processor/32-bit
microcontroller with four embedded MicroEngines to perform the high-speed Layer 3 routing
functions.
A functional block diagram is provided in Figure 8-2. The front-end of the NP Interface design
incorporates a Gigabit Ethernet (GbE) switch device that provides all Layer 2 management. The
back-end of the NP Interface design incorporates an FPGA to provide the WAN framing and
deframing, plus the interface into the main SLM-5650A modem design.
