Configuring Channelized OC12 Interfaces
On Channelized OC12 PICs, you can configure 12 T3 channels per port. To configure
channelized OC12 interface properties, you can include the
t3-options
SONET/SDH options are ignored, and some can only be configured for channel 0,
though they apply equally to all channels. The
is also ignored.
For T3 channels on a channelized OC12 interface, the
only for channel 0; it is ignored if included in the configuration of channels 1 through
11. The clock source configured for channel 0 applies to all channels on the
channelized OC12 interface. The individual T3 channels use a gapped 45-MHz clock
as the transmit clock. When you configure the clock source for a channelized
interface—

Aggregated SONET/SDH Interfaces" on page 936.
