Configuring Line Use
You can use a line as a single E1 or T1 line, as PRI B channels, as fractional E1 or T1
lines divided into channel groups, or for inband signaling for channelized T1.
Note – T1 and E1 lines require an external clock signal provided by the device to which
the PortMaster is connected, or by the telephone company network.
To configure a line, use the following command. Table 11-1 explains the line use
options.
Command> set Line0 isdn|t1|e1|fractional|isdn-fractional|inband
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.
Setting Channel Groups
You can divide the channels of a T1 or E1 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 or E1 line, use the following command. Table 11-1
explains the channel group options.
