Caution – If you configure a line for fractional T1 or fractional ISDN and reset the
!
board before configuring the group and channels, you will no longer be able to see and
configure the line.
You use the fractional keyword in this command to break up a channelized T1 line
into groups. The isdn-fractional keyword refers to PRI only.

Configuring Fractional Settings

The PortMaster 4 supports fractional service on T1, E1, or ISDN PRI lines. To configure a
line for fractional use, you must create channel groups and assign channel numbers.
You must also set the channel rate for a fractional T1 or E1 line.

Setting Channel Groups

You can divide the channels of a T1, E1, or ISDN PRI line into numbered groups after
the line type has been set to fractional with the set Line0 fractional command.
To set the channel group for a T1, E1, or ISDN PRI line, use the following command.
Table 10-2 explains the channel group options.
Command> set Line0 group Cgroup channels Channel-list
