Software release
- JUNOS 5.5 and later
Description
- Two OC3 ports
- Power requirements: 0.41 A/48 V @ 20 W
- Intelligent queuing (IQ) PICs support fine-grained queuing per logical interface.
- Conforms to ANSI T1.105-1991 and T1E1.2/93-020R1
- ATM and SONET/SDH standards compliant
- Alarm and event counting and detection
- Compatible with well-known ATM switches
- ATM switch ID, which displays the switch IP address and local interface name of the adjacent Fore ATM switches
- Optical interface support—see Table 3
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
