EIA-530 PIC (M10i Router)
Software release | - Junos OS Release 6.0 and later
|
Description | - Two EIA-530, X.21 or V.35 serial ports
- Power requirement: 0.07 A @ 48 V (3.4 W)
|
Hardware features | - 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
|
Software features | - 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)
|
Cables and connectors | - 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
|
LEDs | 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)
|
Instrumentation (counters) | - Per-port packet and byte counters
- Resynchronization counters:
- Number of resynchronizations initiated
- Time of last resynchronization
