Note The CLI allows SDH framing and channel mappings although these

configurations are not supported currently. Do not configure the channelized

OC-12 modules for SDH framing.

The 1-port (see Figure 1-11) channelized OC-12 OSMs support channelized

configurations down to OC-3 and DS3. The channelized OC-12 modules can be

configured as multiple OC-3 or DS3 channelized interfaces, or a mix of OC-3,

DS3, and DS3 subrate channelized interfaces. Each port uses LC fiber connectors

for use with SMF.

Table 1-10 2-Port OC-12 ATM Modules

The 2-port OC-12 Asynchronous Transfer Mode (ATM) OSM (see Figure 1-12)

provides:

• Standards-compliant SONET/SDH interface; SONET/STS-3c and

SDH/STM-1c framing and signaling overhead.

• Two SC fiber ports providing full-duplex operation at 622 Mbps per port

(half-duplex operation is not supported).
