Software release
- JUNOS 5.6 and later
Description
- Ten E1 ports
- Power requirement: 0.15 A/48 V @ 7.2 W
- Intelligent queuing (IQ) PICs support fine-grained queuing per-logical interface.
- Channelization: E1, DS0
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.
