Example: Configuring a Channelized Interface to Drop and Insert Time Slots

No special configuration beyond device initialization is required before configuring this feature.

To configure or edit the drop-and-insert feature on a channelized T1/E1/ISDN PRI interface:

  1. Create a new interface.

    [edit]user@host# edit interfaces ct1-3/0/0
  2. Configure the clock source and partition on the interface.

    [edit]user@host# set interfaces ct1-3/0/0 clocking externaluser@host# set interfaces ct1-3/0/0 partition 1 timeslots 1-10user@host# set interfaces ct1-3/0/0 partition 1 interface-type ds

    Note: While configuring the drop-and-insert feature, you must ensure that both ports on the channelized T1/E1 PIM run on the same clock.

  3. Create another interface.

    [edit]user@host# edit interfaces ct1-3/0/1
  4. Configure the clock source and partition on the interface.

    [edit]user@host# set interfaces ct1-3/0/1 clocking external interface ct1-3/0/0user@host# set interfaces ct1-3/0/1 partition 1 timeslots 1-10user@host# set interfaces ct1-3/0/1 partition 1 interface-type ds

    Note: While configuring the drop-and-insert feature, you must ensure that both ports on the channelized T1/E1 PIM run on the same clock.

  5. Create additional interfaces and configure the drop-and-insert feature on those interfaces.

    [edit]user@host# edit interfaces ds-3/0/0:1user@host# set interfaces ds-3/0/0:1 data-input interface ds-3/0/1:1

    Note: Both interfaces configured for the drop-and-insert feature must exist on the same PIM. For example, you can configure ds-3/0/0:1 as the data input interface for ds-3/0/1:1, but not for ds-4/0/0:1.
