Command Reference
■ Only one timeslot bundling mode is supported on one CE1/PRI interface at a time.
In other words, you cannot use this command and the
channel-set command
together.
When creating a pri-set on a CT1/PRI interface, note the following:
■ Timeslot 24 is D channel for transmitting signaling; it cannot form a bundle that
includes itself only. The attempts to bundle only timeslot 24 will fail.
■ In a pri-set formed by timeslot bundling on a CT1/PRI interface, timeslot 24 is used
as D channel for signaling transmission, and other timeslots as B channels for data
transmission. You may randomly bundle these timeslots into a pri-set (as the D
channel, timeslot 24 is automatically bundled). The logic features of this pri-set will
be the same like those of an ISDN PRI interface. If no timeslot is specified, all the
timeslots are bundled into an interface similar to an ISDN PRI interface in the form
of 23B+D.
■ The system automatically creates a serial interface after timeslot bundling on the
interface. This serial interface has the same logic features of ISDN PRI interface.
The serial interface is numbered in the form of serial
number:23, where number
is maximum serial interface number plus 1.
■ Only one timeslot bundling mode is supported on a CT1/PRI interface at a time. In
other words, you cannot use this command and the
channel-set command
together.
