By default, T1 interfaces use extended superframe framing format. You can configure SF (superframe) as an alternative.
To have the interface use the SF framing format, include the framing statement at the [edit interfaces interface-name t1-options] hierarchy level, specifying the sf option:
- [edit interfaces interface-name t1-options]
-
framing sf;
To explicitly configure ESF framing, include the framing statement at the [edit interfaces interface-name t1-options] hierarchy level, specifying the esf option:
- [edit interfaces interface-name t1-options]
-
framing esf;
