204 C 3: I M C
HAPTER NTERFACE ANAGEMENT OMMANDS
Description
Using the t1 unframed command, you can set a T1 line on a CT3 interface to work
in unframed mode (T1 mode). Using the undo t1 unframed command, you can set
the T1 line on the CT3 interface to work in framed mode (CT1 mode).
By default, T1 lines are working in framed mode.
A T1 line in unframed mode does not contain the frame control information and
cannot be divided into timeslots. Naturally, no timeslot bundling can be performed
on it. In this case, the system automatically creates a serial interface numbered
serial number / line-number:0 for it. This interface operates at 1544 Kbps and has
the same logic features of a synchronous serial interface on which you can make
other configurations.
For the related command, see t1 channel-set.
Example
Set the first T1 line on the T3 interface to work in unframed mode.

Parameter
t3: Sets the CT3 interface to work in unchannelized mode.
ct3: Sets the CT3 interface to work in channelized mode.
Description
Using the using command, you can configure the operating mode of a CT3
interface. Using the undo using command, you can restore the default setting.
By default, the CT3 interface is working in channelized mode.
Only when the CT3 interface is working in channelized mode can you configure
the T1 lines on it.
When the CT3 interface is working in unchannelized mode, the system
automatically creates a serial interface numbered serial number / 0:0 for it. This
interface operates at 44.736 Mbps and has the same logic features of a
synchronous serial interface on which you can make other configurations.
Example
Configure the interface T3 1/0/0 to work in unchannelized mode.
