Usage Guidelines
Framing is used to synchronize data transmission on the line. Framing allows the hardware to
determine when each packet starts and ends. The two choices for T1 framing are Super Frame (SF), also
known as D4, and Extended Super Frame (ESF). The ESF scheme is a newer standard and is enabled by
default. To choose the T1 framing scheme, use the following command:
If you choose to use SF framing, you should disable yellow alarm detection for the T1 line. SF framing
may generate false yellow alarms. See the command "config ports snmp alert" on page 1328 to disable
yellow alarms.
Example
The following command sets framing to SF for the T1 ports:
config ports 3:1-3:4 t1 framing sf
