Setting the Emulation Mode
To set the framing emulation mode, include the framing statement at the [edit chassis
fpc fpc-slot pic pic-slot] hierarchy level:
[edit chassis fpc fpc-slot pic pic-slot]
user@host# set framing (t1 | e1);
After a PIC is brought online, interfaces are created for the PIC’s available ports according
to the PIC type and the framing option used:
•
If you include the framing t1 statement (for a T1 Circuit Emulation PIC), 12 CT1 interfaces
are created.
•
If you include the framing e1 statement (for an E1 Circuit Emulation PIC), 12 CE1 interfaces
are created.
NOTE: If you set the framing option incorrectly for the PIC type, the commit
operation fails.
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.
Bit error rate test (BERT) patterns with all ones received by T1/E1 interfaces
on Circuit Emulation PICs configured for SAToP do not result in an alarm
indication signal (AIS) defect. As a result, the T1/E1 interfaces remain up.

Setting the Encapsulation Mode
E1 channels on Circuit Emulation PICs can be configured with SAToP encapsulation at
the provider edge (PE) router, as follows:
NOTE: The below mentioned procedurecan be used to configure T1 channels
on circuit emulation PICs with SAToP encapsulation at the PE router.
1. In the configuration mode, go to [edit interfaces e1-fpc-slot/pic-slot/port] hierarchy
level.
