EIA-530 PIC

■Supports four queues per port

■Random early detection (RED)

■Transmitter Signal Element Timing is looped from the timing received on the Transmitted Signal Element DCE. EIA-530 ports support the ability to invert the Transmit Data Element. The EIA-530 ports support the following rates:

■2.048 Mbps

■2.341 Mbps

■2.731 Mbps

■3.277 Mbps

■4.09 Mbps

■5.461 Mbps

■8.192 Mbps

■16.384 Mbps

■V.35 ports support up to 2.048 Mbps

■X.21 ports support up to 10 Mbps

■Encapsulations:

■High-Level Data Link Control (HDLC)

■Frame Relay

■Circuit cross-connect (CCC)

■Translational cross-connect (TCC)

■Point-to-Point Protocol (PPP)

■Two DB-25 male connectors (one per port, included with PIC)

■V.35 requires an EIA-530 to V.35 cable and connects to a V.35 DTE 34-pin Winchester type male cable (one per port)

■X.21 requires an EIA-530 to X.21 cable and connects to a X.21 DTE DB-15 male cable

Three bicolor per port:

■Data set ready (DSR):

■Green—DSR is detected or ignored

■Red—DSR expected but not present

■Data carrier detect (DCD):

■Green—DCD is detected or ignored

■Red—DCD expected but not present

■Resynchronization:

■Green—Keepalives are being received

■Red—Data terminal ready (DTR) toggled from low to high (resynchronization pulses are being sent)

■Per-port packet and byte counters

■Resynchronization counters:

■Number of resynchronizations initiated

■Time of last resynchronization
