e1 set clock
e1 set frame-format
Command Reference Guide
When an E1 line operates at framed (CE1) mode, you can bundle the timeslots
on it. The system will automatically create a serial interface numbered serial
number / line-number:set-number. For example, the serial interface created by
the channel-set 0 of the first e1 line on E3 7/0 will be numbered 7/0/1:0. This
interface can operate at N x 64 Kbps and has the same logic features of a
synchronous serial interface on which you make other configurations.
For related command, see e1 unframed.
Example
Bundle a 128Kbps serial interface on the first E1 line on the interface E3 1/0/0.
[NEC-PHILIPS-E3 1/0/0]e1 1 channel-set 1 timeslot-list 1,2
Syntax
e1 line-number set clock { master | slave }
undo e1 line-number set clock
View
CE3 interface view
Parameter
line-number: E1 line number in the range of 1 to 16.
master: Adopts the internal clock mode.
slave: Adopts the line clock mode.
Description
Using the e1 set clock command, you can set the clock mode for an E1 line on
a CE3 interface. Using the undo e1 clock command, you can restore the
default setting.
By defaults, the E1 lines on a CE3 interface adopt line clock.
The E1 lines on a CE3 interface working in channelized mode are allowed to
use separate clocks.
Example
Configure the first E1 line on the E3 interface to adopt line clock mode.
[NEC-PHILIPS-E3 1/0/0]e1 1 set clock slave
Syntax
e1 line-number set frame-format { crc4 | no-crc4 }
undo e1 line-number set frame-format
View
CE3 interface view
Parameter
line-number: E1 line number in the range of 1 to 16.
crc4: The frame format adopted by an E1 line is crc4.
no-crc4: The frame format adopted by an E1 line is no-crc4.
