Configuration Tasks
Configuring Framing
Framing is used to synchronize data transmission on the line. Framing allows the hardware to determine
when each packet starts and ends. To configure framing, use the following commands:
Verifying Framing Configuration
Use the show controllers serial command to display the framing method:
Router# show controllers serial 2/0/0
Serial2/0/0 -
Framing is c-bit, Clock Source is Line
Bandwidth limit is 44210, DSU mode 0, Cable length is 10
rx FEBE since last clear counter 2, since reset 0
Data in current interval (546 seconds elapsed):
0 Line Code Violations, 0 P-bit Coding Violation
0 C-bit Coding Violation
0 P-bit Err Secs, 0 P-bit Sev Err Secs
0 Sev Err Framing Secs, 0 Unavailable Secs
0 Line Errored Secs, 0 C-bit Errored Secs, 0 C-bit Sev Err Secs
Data in Interval 1:
0 Line Code Violations, 0 P-bit Coding Violation
0 C-bit Coding Violation
0 P-bit Err Secs, 0 P-bit Sev Err Secs
0 Sev Err Framing Secs, 0 Unavailable Secs
0 Line Errored Secs, 0 C-bit Errored Secs, 0 C-bit Sev Err Secs
Command Purpose
Router# configure terminal Enters global configuration mode.
Router(config)# interface serial slot/subslot/port Selects the interface to configure and enters
interface configuration mode.
• slot/subslot/port—Specifies the location of the
T3/E3 interface. See the
“Specifying the
Interface Address on a SPA” section on
page 17-5.
T3
Router(config-if)# framing {bypass | c-bit |
m13}
E3
Router(config-if)# framing {bypass | g751|
g832}
Sets the framing on the interface.
• bypass—Configures framing bypass to use
the full T3 or E3 bandwidth.
• c-bit—Specifies C-bit parity framing. This is
the default for T3.
• m13—Specifies M13 framing.
• g751— Specifies g751 framing. This is the
default for E3.
• g832—Specifies g832 framing.
