LAN
The dual 10/100-Mbps Ethernet LAN ports are presented on an RJ-45 connector with an auto-sensing/full- duplex 10Base-T or 100Base-T interface. They also include:
•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
Signaling
Robbed-bit, R1, R2, Q.921/Q.931
Modems
Up to 96/120 V.92, V.90, K56Flex, V.34+, ISDN B-channel digital calls (additional ports/functionality can be added by installing optional PMC expansion modules), or 64 kbps and 56 kbps DOVBS (data over voice bearer services).
RS-232 control port
An RS-232 port provides for initial configuration of the RAS. The RS-232 port also supports:
•Asynchronous data at 19.2 kbps
•An RJ-45 connector with EIA-561 pinout
•A VT-100 console management interface
•Hardware CD and DTR signals for external modem support
Power system
The Model 3125 obtains power modular power supplies installed in the cPCI chassis via PCMG 2.11 47-pin power connectors (one for the front blade and one for the rear blade). Maximum power consumption is
43 watts.
Central processing unit
The 3125 uses a RISC-based Intel model i80960VH processor operating at 100 MHz. The CPU executes the LAN protocol, IP routing, WAN protocol, management and authentication software. It also supports:
•4 Mbytes of FLASH memory
•32 Mbytes of EDO DRAM
Temperature
Operating range: 32 to 104 °F (0 to +40 °C)
Altitude
Maximum operating altitude: 15,000 feet (4,752 meters)
Humidity
5 to 95% relative humidity (RH) at 122 °F (50 °C)
