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
