Channelized OC12 IQ PIC

Image g003043.gif

Software release
  • JUNOS 5.6 and later
Description
  • One OC12 port
  • Power requirement: 0.23 A/48 V @ 10.8 W
  • Intelligent queuing (IQ) PICs support fine-grained queuing per logical interface.
  • Channelization: OC3, DS3, DS1, DS0
  • Optical interface support — see Table 6

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.
