Example: Configuring Channelized OC12 IQ Interfaces

Configuring a SONET/SDH Interface

Configure a channelized OC12 interface as an unpartitioned, clear channel:

[edit interfaces]
coc12-5/0/0 {
no-partition interface-type so; # so-5/0/0
}

Configuring Multiple Interface Types

Configure the following interfaces on a Channelized OC12 IQ or IQE PIC:
  1. An OC3 interface
  2. Another OC3 interface
  3. A channelized OC1 partitioned into T1 interfaces
  4. A channelized OC1 converted into a T3 interface
  5. A channelized OC1 partitioned into T1 interfaces and channelized T1s, which are partitioned into NxDS0 interfaces
  6. A channelized OC1 converted into a channelized T3, which is partitioned into T1 interfaces
  7. A channelized OC1 converted into a channelized T3, which is partitioned into T1 interfaces and a channelized T1, which is partitioned into NxDS0 interfaces
  8. A channelized OC1 partitioned into channelized T1s, which are partitioned into NxDS0 interfaces
