Model 2616RC T-DAC User Manual 1 • Introduction
• 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 2616RC. 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 2616RC obtains power from the Patton ForeFront chassis. Total power consumption is a maximum of
43
watts provided by modular power supplies installed in the Patton ForeFront chassis.
Central processing unit
The 2616RC employs an Intel i960VH RISC processor operating at 100 MHz/100 Mips. The CPU controls
the memory, front/back-panel and management interface for WAN time slot mapping, local switching, loop
-
back and the management system. The memory holds:
• 4 MB Flash ROM
• 8 MB EDO DRAM
System timing
The T1/E1 T-DAC’s system timing may be derived from an internal clock from an on-board chip, external
BITS clock, or a network clock from one of the T1/E1 WAN ports or from the ForeFront system chassis clock.
The clock source may be configured in primary, secondary, or slave mode.
The system timing is configured through the NMS.
