• Two EIA-530, X.21 or V.35 serial ports
• Power requirement: 0.07 A @ 48 V (3.4 W)
Description
• Configured as data terminal equipment (DTE) ports
• Resynchronization signal
• Receives clock rates up to 16 Mbps
• Local, data communications equipment (DCE) local, and DTE remote loopbacks
Hardware features
• Supports four queues per port
• Random early detection (RED)
• Transmitter Signal Element Timing is looped from the timing received on the Transmitted
