For example:
[edit chassis fpc 1 pic 0 port 0]
user@host# set speed coc3-cstm1
NOTE: When the speed is set as coc12-cstm4, instead of configuring COC3
ports down to T1 channels and CSTM1 ports down to E1 channels, you
must configure COC12 ports down to T1 channels and CSTM4 channels
down to E1 channels.
Configuring SONET/SDH Framing Mode at the MIC Level
To set the framing mode at the MIC (MIC-3D-4COC3-1COC12-CE) level, for all four ports
on the MIC, include the framing statement at the [edit chassis fpc slot pic slot] hierarchy
level.
[edit chassis fpc slot pic slot]
user@host# set framing (sonet | sdh) # SONET for COC3/COC12 or SDH for CSTM1/CSTM4
After a MIC is brought online, interfaces are created for the MIC’s available ports on the
basis of the MIC type and the framing option used.
•
If you include the framing sonet statement, four COC3 interfaces are created when the
speed is configured as coc3-cstm1.
•
If you include the framing sdh statement, four CSTM1 interfaces are created when the
speed is configured as coc3-cstm1.
•
If you include the framing sonet statement, one COC12 interface is created when the
speed is configured as coc12-cstm4.
•
If you include the framing sdh statement, one CSTM4 interface is created when the
speed is configured as coc12-cstm4.
•
If you do not specify framing at the MIC level, then the default framing is SONET for
all the ports.
NOTE: If you set the framing option incorrectly for the MIC type, the commit
operation fails.
Bit error rate test (BERT) patterns with all binary 1s (ones) received by CT1/CE1
interfaces on Circuit Emulation MICs configured for CESoPSN do not result
in an alarm indication signal (AIS) defect. As a result, the CT1/CE1 interfaces
remain up.
