Configuring Fractional Settings
10-6 PortMaster 4 Configuration Guide
To configure a line, use the following command. Table 10-1 explains the line use
options.
Command> set Line0|isdn|t1|e1|fractional|isdn-fractional|inband
Table 10-1 Line Use Options
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
