Software release
- JUNOS 6.1 and later
Description
- Four DS3 ports
- Power requirements: 0.41 A/48 V @ 20.0 W
- Intelligent queuing (IQ) PICs support fine-grained queuing per logical interface.
- ATM standards compliant
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
- 16-MB SDRAM memory for ATM segmentation and reassembly (SAR)
- ATM switch ID
- Configurable framing options:
- C-bit with ATM direct mapping
- C-bit with Physical Layer Convergence Protocol (PLCP) framing (default)
- M23 ATM direct mapping
- M23 with PLCP framing
- Internal and loop timing
Software features
- Per-virtual circuit (VC) and per-virtual path (VP) traffic shaping
- Unspecified bit rate (UBR) traffic shaping
- Fine-grained variable bit rate (VBR) traffic shaping
- Multiprotocol Label Switching (MPLS) circuit cross-connect (CCC)
- ATM Inverse Address Resolution Protocol (ARP), which enables routers to automatically learn the IP address of the router on the far end of an ATM permanent virtual circuit (PVC)
- Simple Network Management Protocol (SNMP):
- Management Information Base (MIB) 2 (RFC 1213)
