Software release
- JUNOS 6.1 and later
Description
- Four E3 ports
- Power requirement: 0.38 A/48 V @ 18 W
- Intelligent queuing (IQ) PICs support fine-grained queuing per-logical interface.
Note: On the M5, M10, M20, M40, and M160 routers, this PIC requires an enhanced FPC. See the hardware guide for your router for more information.
Hardware features
- Clear-channel (34.368-Mbps) and subrate E3
- Unframed or ITU G.751 framing
- Data Service Unit (DSU) functionality
- Subrate and scrambling:
- Digital Link/Quick Eagle
- Kentrox
- HDB3 line encoding
- Full Bit Error Rate Testing (BERT)
- Local and remote loopback testing
Software features
- Quality of Service (QoS) per port: Weighted Round Robin (WRR), Random Early Drop (RED), Weighted Random Early Drop (WRED)
- Simple Network Management Protocol (SNMP): E3 MIB, QoS MIB
- Input policing and output shaping
- Provider-side rate limiting
- Full data link connection identifier (DLCI) range with sparse channel numbering
- Per-DLCI queues with weighted deficit round robin and strict priority
- Encapsulations:
- High-level Data Link Control (HDLC)
- Frame Relay
- Multiprotocol Label Switching (MPLS) circuit cross-connect (CCC)
- MPLS translational cross-connect (TCC)
- Point-to-Point Protocol (PPP)
Note: Extended support for graceful Routing Engine switchover has been added for this PIC. To configure graceful Routing Engine switchover, you must be running JUNOS release 7.0 or later.
Cables and connectors
- Standard E3 BNC coaxial cable interfaces
LEDs One tricolor per port:
- Off—Not enabled
- Green—Online with no alarms or failures
- Amber—Online with alarms for remote failures
- Red—Active with a local alarm; router has detected a failure
Alarms, errors, and events
- Alarm Indication Signal (AIS)
- Equipment failure (does not affect service)
- Frame error
- Line code violation
- Loss of Signal (LOS)
- Out of Frame (OOF)
- Yellow alarm bit (A-bit) disagreements
Instrumentation (counters)
- Layer 2 per-queue packet and byte counters
