E1 Set Clock - HP 6600 Command Reference Manual

When an E1 line operates in framed (CE1) mode, you can bundle timeslots on it into channel sets. For
each channel set, the system automatically creates a serial interface numbered serial
number/line-number:set-number. For example, the serial interface formed by channel set 0 on the first E1
line on E3 1/0 is numbered 1/0/1:0. This interface can operate at N × 64 kbps, and is logically
equivalent to a synchronous serial interface on which you can make other configurations.
Examples
# Create a 128 kbps serial interface on the first E1 channel on interface E3 2/0/0.
<Sysname> system-view
[Sysname] controller e3 2/0/0

e1 set clock

Use e1 set clock to configure clock source for an E1 line on the CE3 interface.
Use undo e1 set clock to restore the default.
Syntax
e1 line-number set clock { master | slave }
undo e1 line-number set clock
Default
The clock source for an E1 line on the CE3 interface is line clock.
Views
CE3 interface view
Default command level
2: System level
Parameters
line-number: E1 line number in the range of 1 to 16.
master: Adopts the internal clock as the clock source.
slave: Adopts the line clock as the clock source.
Usage guidelines
When the CE3 interface is working in channelized mode, you can set separate clock for each E1 line on
it.
Examples
# Use the internal clock as the clock source on the first E1 line on interface E3 2/0/0.
<Sysname> system-view
