Example: Channelized E1 IQ Interface Configuration

 
Figure 1: Channelized E1 IQ Interface Example
Channelized E1 IQ Interface Example

 

This example shows two ways to configure a channelized E1 IQ interface. Figure 1 shows a fractional E1 method and the NxDS0 method seen previously in the complex OC12 configuration example (see Example: Complex Configuration for a Channelized OC12 IQ Interface). The NxDS0 method breaks the channelized E1 IQ interface into discrete DS0 blocks, whereas the fractional method creates a clear channel E1 that is segmented by time slots.

To configure NxDS0 channels, include the partition statement at the [edit interfaces ce1-fpc /pic/port] hierarchy level. Include the timeslots and interface-type ds options to create the desired number of NxDS0 interfaces in time slots 2 through 32.

To configure a fractional E1 on a channelized E1 IQ interface, include the no-partition statement at the [edit interfaces ce1-fpc/pic/port] hierarchy level. After you commit this configuration, configure standard E1 options on the clear channel E1 interface. Include the timeslots statement at the [edit interfaces e1-fpc/pic/port e1-options] hierarchy level. Time slot 1 is reserved; use time slots 2 through 32.

Verifying Your Work

To verify correct operation of a channelized E1 IQ interface, use the following commands:

  • show interfaces

  • show interfaces controller

  • show interfaces interval (for E1 and channelized E1 channels)

To view the interface names of the physical channelized E1 IQ interface and the resulting interfaces configured on the channelized IQ interface, use the show interfaces controller command:

user@RouterA> show interfaces controller ce1-1/2/3

To view information about the physical channelized interface, include the ce1-fpc/pic/port option with the show interfaces command:

user@RouterA> show interfaces ce1-1/2/3

To view information about an NxDS0 interface, include the ds-fpc/ pic/port:channel option with the show interfaces command:

user@RouterA> show interfaces ds-1/2/3:1 detail

To view information about the fractional E1 interface, include the e1-fpc/pic/port option with the show interfaces command:

user@RouterA> show interfaces e1-1/2/6 detail
