LAN
The 10/100-Mbps Ethernet LAN port is presented on an RJ-45 connector with an auto-sensing/full-duplex 10Base-T or 100Base-T interface. Also included are:
•100Base-TX half-/full-duplex operation (100 + 100)
•10Base-T half-/full-duplex operation (10 + 10)
•Auto detection and fallback
•10/100 Mbps link and status indicators
RS-232 control port
The RS-232 port provides for initial configuration of the Model 3196RC. The RS-232 port supports:
•Asynchronous data rates of 19.2 kbps, 8 data bits, no parity, 1 stop bit.
•An RJ-45 connector with EIA-561 pinouts
•A management interface that supports VT-100 terminals
•Hardware flow control (RTS and CTS)
Power system
The 3196RC obtains power from the CPCI chassis via PCMG 2.11 47-pin power connectors on the front and rear blade. Total power consumption is a maximum of 43 Watts, provided by modular power supplies installed in the CPCI chassis.
Central processing unit
The 3196RC employs an Intel i960VH RISC processor operating at 100 MHz/100 Mips. The CPU controls the memory, front/back-panel and management interface for iDSL port/WAN time slot mapping, local switching, loopback and the management system. The memory holds:
•4 MB Flash ROM
•8 MB EDO DRAM
iDSL ports
The 16 iDSL ports operate at data-rates up to 144 kbps and are accessible via the RJ-21X 50-pin Telco connec- tor. Each port uses one twisted-pair (2-wires) for full-duplex communication. The iDSL ports can be concen- trated into TDM data output on the WAN ports. Other features include:
•Line encoding defined by iDSL
•“Plug-and-Play” automatic configuration between the multiplexer and the CPE modems
•Built-in surge protection
•Configuration parameters and line status indicators accessible to upper-level utility or application software
