Understanding Channelized Interface Clear Channels

Each port on a channelized T1/E1/ISDN PRI PIM is software configurable as a T1 or E1 clear channel. You can partition each port into up to 24 DS0 channels on a T1 interface or up to 31 DS0 channels on an E1 interface, and can insert channels from one port into another with the drop-and-insert feature. Channelized T1/E1/ISDN PRI ports can also be partitioned into channels for ISDN PRI service.

Note: When you configure a T1 or an E1 interface on the SRX-GP-QUAD-T1-E1 or SRX-GP-DUAL-T1-E1, the line encoding and the framing must be specified under the ct1-n/n/n interface, whereas the remaining T1 or E1 specific configuration items must be configured under the t1-n/n/n or e1-n/n/n interface, respectively. Channelized T1/E1/ISDN PRI ports can also be partitioned into channels for ISDN PRI service.
