Configuring CT1/PRI
Interface in CT1 Mode
Configuring an CT1/PRI
Interface operating as a
PRI interface
When it is working as a PRI interface, timeslot 24 is used as a D channel for
■
signaling transmission. Therefore, only a group of timeslots except timeslot 24
can be chosen as the B channel. This timeslot group is bundled together with
timeslot 24 to form a PRI set. This PRI set will work as an interface logically
equivalent to an ISDN PRI interface where you can configure PPP at the data
link layer, IP or IPX at the network, DCC, and other configurations.
The timeslots on a CT1/PRI interface can be bundled into either channel sets or a
PRI set at a time.
Follow these steps to configure a CT1/PRI interface in CT1 mode:
To do...
Enter system view
Enter CT1/PRI interface view
Bundle timeslots on the
interface into channel sets
Configure other interface
parameters
For each channel set, the system automatically creates a serial interface numbered
serial number:set-number. This interface is logically equivalent to a synchronous
serial interface where you can make other configurations about:
Data link protocol such as

"IP Addressing Configuration" on page 623

"Backup Center Configuration" on page 1961
■
primary or secondary interface for backup

Enter system view
Enter CT1/PRI interface view
Bundle timeslots on the
interface into a PRI set
