Command Reference Guide
framing
Use the framing command to configure the network framing format for a T3 physical interface. Use the no
form of this command to return to the default value. Variations of this command include:
framing cbit
framing m13
Syntax Description
cbit
m13
Default Values
By default, all T3 interfaces are configured for cbit parity framing.
Command History
Release 6.1
Functional Notes
M13 is an asynchronous framing format that uses all 21 DS3 M-Frame C-bits for bit stuffing indicators.
End-to-end path parity and datalink capabilities are not provided by the standard M13 format. C-bit parity
framing differs from M13 by allowing monitoring of the data path (end-to-end) and supporting out-of-band
(OOB) data links.
Usage Examples
The following example configures the T3 interface for m13 framing:
(config)#interface t3 1/1
(config-t3 1/1)#framing m13
60000CRG0-35E
Configures the interface for C-bit parity framing.
