framing [m13 | cbit]
Use the framing command to configure the network framing format for a T3 physical interface.
Syntax Description
m13 Configures the interface for M13 framing.
cbit Configures the interface for C-bit parity framing.
Default Value
By default, all T3 interfaces are configured for C-bit parity framing.
Applicable Platforms
This command applies to the NetVanta 5000 Series.
Command History
Release 6.1 Command was introduced.
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
data links.
Usage Example
The following example configures the T3 interface for M13 framing:
(config)#interface t3 1/1
(config-t3 1/1)#framing m13
