Overview of Channelized Interfaces

Channelized interfaces enable you to configure a number of individual channels that subdivide the bandwidth of a larger interface and minimize the number of Physical Interface Cards (PICs) that an installation requires.

Note: Channelized intelligent queuing (IQ) and channelized enhanced intelligent queuing (IQE) interfaces require M-series Enhanced Flexible PIC Concentrators (FPCs).

Wherever JUNOS configuration guides refer to channelized interfaces and PICs without the “intelligent queuing IQ”, or “IQE” descriptor, they are referring to the original channelized interfaces and PICs.

For SONET/SDH interfaces you configure on Channelized OC3 IQ, Channelized OC3 IQE, Channelized OC12 IQ, Channelized OC12 IQE, Channelized STM1 IQ, and Channelized STM1 IQE PICs, aggregated SONET is not supported.

For channelized IQ and IQE logical interfaces, you can configure class of service (CoS). For more information, see the JUNOS Class of Service Configuration Guide.
