NOTE: When T1 is used for SAToP, the T1 facility data-link (FDL) loop is not
supported on the CT1 interface device. The is because SAToP does not analyze
T1 framing bits.

Configuring T1/E1 Framing Mode at the MIC Level
To configure the framing emulation mode at the MIC level.
1. Go to the [edit chassis fpc fpc-slot pic pic-slot] hierarchy level.
[edit]
[edit chassis fpc fpc-slot pic pic-slot]
2. Configure the framing emulation mode as E1 or T1.
[edit chassis fpc fpc-slot pic pic-slot]
user@host# set framing (t1 | e1)
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 t1 statement, 16 channelized T1 (CT1) interfaces are created.
•
If you include the framing e1 statement, 16 channelized E1 (CE1) interfaces are created.
NOTE: If you set the framing option incorrectly for the MIC type, the commit
operation fails.
By default, t1 framing mode is selected.
Circuit Emulation PICs with SONET and SDH ports require prior channelization
down to T1 or E1 before you can configure them. Only T1/E1 channels support
SAToP encapsulation or SAToP options.
