Channelized OC3 IQ and IQE Overview
Channelized intelligent queuing (IQ) and channelized enhanced intelligent queuing (IQE) interfaces allow arbitrary and dynamic channelization of serial links, allowing greater flexibility than regular channelized interfaces.
On each port of a Channelized OC3 IQ or a Channelized OC3 IQE interface, you can configure the following interface types:
- One OC3 SONET interface
- Up to three T3 interfaces
- Up to 84 T1 interfaces
- Up to three E3 interfaces (COC3 IQE PICs in SDH mode)
- Up to 63 E1 interfaces (COC3 IQE PICs in SDH mode)
- Up to 336 NxDS0 interfaces on an M Series router
- Up to 768 NxDS0 interfaces on a T Series router
Figure 1 shows an example of how a Channelized OC3 PIC might be partitioned. In the figure, the OC3 SONET interface would be a standalone interface because it would use the entire bandwidth of the PIC. The same applies to each port of the 2–port Channelized OC3 Enhanced IQ (IQE) PIC.

You can configure the following encapsulation types:
- PPP
- Frame Relay
- Cisco HDLC
- CCC
- TCC
- MPLS—On IQE interfaces.

To configure channelized interfaces, include the following statements at the [edit interfaces interface-name] hierarchy level:
