Network Processor (Np) Module Option; T1/E1, T2/E2 Module Option; Low Voltage Differential Signaling (Lvds) Module Option; 10/100/1000 Baset Gigabit Ethernet (Gbe) Module Option - Comtech EF Data SLM-5650A Installation And Operation Manual

1.3.1.3.3

Network Processor (NP) Module Option

The optional NP Interface is Comtech EF Data's third generation IP router, Ethernet Bridge, and
BPM 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: -25 to 50°C
1.3.1.3.4 G.703 T1/E1, T2/E2 Module Option
Appendix D. OPTIONAL DATA INTERFACE MODULES
The optional G.703 T1/E1, T2/E2 interface is designed for full duplex capability and is
automatically configured for simplex transmit or simplex receive operation. The interface
operates at the digital hierarchy bit rates of 1.544, 2.048, 6.312, and 8.448 Mps as defined by
ITU-T G.703.
1.3.1.3.5

Low Voltage Differential Signaling (LVDS) Module Option

Appendix D. OPTIONAL DATA INTERFACE MODULES
The optional LVDS interface provides a physical and electrical interface between an SLM-5650A
modulator and demodulator and signal sources operating with LVDS electrical characteristics.
1.3.1.3.6

10/100/1000 BaseT Gigabit Ethernet (GbE) Module Option

Appendix D. OPTIONAL DATA INTERFACE MODULES
The optional 10/100/1000 BaseT Gigabit Ethernet (GbE) interface performs a simple bridge
function and passes IP packets, unaltered, in each direction between the Local Area Network
(LAN) (10/100/1000 BaseT interface) and Wide Area Network (WAN) (SLM-5650A
modulator/demodulator).
IP packet traffic is framed via High-level Data Link Control (HDLC) encapsulation by the
SLM-5650A logic, and the SLM-5650A is both the origination and termination point for HDLC
encapsulation. HDLC CRC-16 verification is performed on all received (from WAN) HDLC frames.
