be created on a CT3 interface in CT3 mode is either M × 1.536 Mbps (where M ranges from 1 to
28) or N × 56 kbps or N x 64 kbps (where N ranges from 1 to 300).
When a T1 line is working in unframed (T1) mode, the system automatically creates a serial interface
named serial number/line-number:0 for it. This interface operates at 1544 kbps and is logically
equivalent to a synchronous serial interface where you can make other configurations.
When the T1 line is working in framed (CT1) mode, you can bundle timeslots on it. The system
automatically creates a serial interface named serial number/line-number:set-number for it. This
interface operates at N × 64 kbps or N × 56 kbps and is logically equivalent to a synchronous serial
interface where you can make other configurations.

The default operating mode is CT3
mode.
4. Enable FT3 mode and set the
DSU mode or the subrate.
ft3 { dsu-mode { 0 | 1 | 2 | 3 | 4 }
| subrate number }
Optional.
By default, DSU mode 0 (the digital
link mode) is adopted, and the
subrate is 44210 kbps.
5. Set other interface
parameters.
See "Configuring other CT3
interface parameters."
Optional.
Serial interfaces created on CT3 interfaces support PPP, HDLC, and FR at the data link layer, and IP at the
network layer. Configure link layer protocols, and IP address for the CT3 interface if the network requires.
