Parameter Function Values
Administrative
Status
Controls whether the selected
recovered clock source is active or
not
UP — Adaptive clock recovery is enabled.
DOWN — Adaptive clock recovery is disabled. This
state should be selected as long as the source
configuration has not yet been completed, or
when it is necessary to stop using this clock
source.
Default: DOWN
Source Quality Specifies the quality of the original
timing source, using the standard
SDH/SONET terminology.
You should not select Stratum 1 and
Stratum 2. Contact RAD Marketing
Department for details
The available selections are STRATUM 1,
STRATUM 2, STRATUM 3, STRATUM 3E, or
STRATUM 4.
Default: STRATUM 4
Network Type Specifies the type of packet switched
network used to transport the
pseudowire
Type A – Switch-based network, for example, an
MPLS/ETH network.
Type B – Router-based network, for example, an
UDP/IP network.
Default: Type B
³ To select a pseudowire as timing reference:
1. To start the nodal timing configuration, navigate to Configuration > System >
Clock Source and then select Source.
2. Make sure that Rx Clock is selected: if not, select this option.
3. After making your selection, the Clock Source screen changes to enable
selecting master and fallback sources.
4. Select Master Port to start the selection of the master timing sources.
5. For each source:
1. To select a physical port, first select RX Clock in the Type column, and
then specify the desired slot and port.
The list includes only slots in which modules with ports capable of
providing a timing reference are installed and/or programmed.
2. To use pseudowires, first select Recovered in the Type column, and then
specify the index number of the recovered clock source to be configured
(see
Table
3-12
). The Slot column displays None in the corresponding
row.
6. After configuring all the required sources, press ESC to return to the Clock
Source screen.
7. To select pseudowires as fallback sources, select Fallback Port and repeat the
same actions. Make sure to select different sources: you cannot select again
a source already included in the Master Port list.
