Configuring a CT1/PRI interface

A CT1/PRI interface can operate only in channelized mode. You can use the interface in the following
ways:
• When it is operating as a CT1 interface, you can divide all the timeslots (numbered 1 to 24)
randomly into groups. Each of these groups can form one channel set. For each channel set, the
system automatically creates a synchronous serial interface.
When it is operating as a PRI interface, you can choose a group of timeslots (except for timeslot 24)
•
as the B channel. Timeslot 24 is the D channel for signaling transmission. You can bundle the B
channel and the D channel to form a PRI set. For the PRI set, an ISDN PRI interface is created
automatically.

Configuring a CT1/PRI interface in CT1 mode

Step
1. Enter system view.
2. Enter CT1/PRI interface view.
3. Bundle timeslots on the
interface into a channel set.
4. (Optional.) Set other interface
parameters.
For each channel set, the system automatically creates a serial interface numbered serial
number:set-number. This interface has the same logical features as a standard synchronous serial
interface and supports the following configurations:
Data link protocols, such as PPP and HDLC.
•
• IP addressing.
Interface backup settings if the interface is used as a primary or backup interface.
•
NAT and packet filtering if a firewall is to be set up.
•

Configuring a CT1/PRI interface in PRI mode

2. Enter CT1/PRI interface view.

By default, no channel sets are
bundled.
The default timeslot speed is 64
kbps.
The timeslots on a CT1/PRI
interface can be bundled into
either channel sets or a PRI set, but
not both at the same time.
