Channelized Interfaces Overview

Channelized interfaces enable you to configure a number of individual channels that subdivide the bandwidth of a larger interface and minimize the number of PICs that an installation requires. The JUNOS software supports M-series channelized interfaces and M-series channelized Q Performance Processor (QPP) interfaces.

Channelized QPP interfaces require M-series Enhanced FPCs. Wherever the JUNOS Internet Software Configuration Guides refer to channelized interfaces and PICs without the "Q Performance Processor" or "QPP" descriptor, they are referring to the original channelized interfaces and PICs.

This chapter provides a high-level overview of channelized interfaces, focusing mainly on the capabilities, properties, and structure of channelized QPP interfaces:

• Channelized Interface Capabilities
• Data Link Connection Identifiers on Channelized Interfaces
• Clock Sources on Channelized Interfaces
• Channelized QPP Interface Properties
• Structure of Channelized PICs with QPP
