Provisioning the Non-PTP Outputs
Example:
To provision TI/E1 port for an E1 output with a frametype of CAS, CRC enabled,
SSM-bit of 5, zero-suppression on, and to enable the port:
1. Login at the Admin or Config-user level.
2. Type
set port-control t1e1 io output
and press
Enter
.
3. Type
set port-control t1e1 signal-type e1
and press
Enter
.
4. Type
set output e1 frametype t1e1 cas
and press
Enter
.
5. Type
set output e1 crc t1e1 enable
and press
Enter
.
6. Type
set output e1 ssmbit t1e1 5
and press
Enter
.
7. Type
set output e1 zero-suppression t1e1 on
and press
Enter
.
8. Type
set port-control t1e1 state enable
and press
Enter
.
Provisioning TOD+1PPS Output
The TOD output port uses an RS-422 balanced signal level and RJ-45 connector. It
contains the TOD message and the 1PPS signal. The TOD message can be one of
two supported TOD formats: Cisco and China Mobile. At the connector, the 1PPS
signal shares the same timing characteristics as the standalone 1PPS signal from
the 10M/1PPS coaxial connector. These timing characteristics are pulse width, rise
time of the timing edge, and offset from UTC second, but they are separately
configured.
TOD+1PPS Output Example
To configure the TOD port as a TOD+1PPS output with the Cisco TOD format, and
to enable the port, use the following procedure:
1. Login at the Admin or Config-user level.
2. Type
set port-control tod format cisco
and press
Enter
.
3. Type
set port-control tod state enable
and press
Enter
.
Note:
The Cisco TOD message format reports leap seconds using
TAI-UTC. The China Mobile TOD message format reports GPS leap
second using GPS-UTC.
