3.2.4 Configuring the Basic Parameters of E1 Interface
In order that the device on the two ends of E1 trunk will be synchronized in
communication, E1 clock source needs to be configured for the devic e on both ends. At
this stage, there are two ways to select the clock source: generating the clock by itself
and extracting the clock from the line.
When channel-group is successfully configured, the system will create the serial port
corresponding to the channel-group automatically. The number of the new serial port is
“(the number of the serial port where the channel group lies + the t otal num ber of the
serial ports): channel-group number”.
Please use commands controller e1 and interface serial in global configuration m ode
and perform other configurations in E1 controller interface configurat ion mode.
