IQS-8500 Series and IQS-8120NGE/8130NGE
Clock Synchronization
Backplane
The backplane feature allows sharing the same backplane 8 kHz clock for
synchronization group purposes. The other module must support the
backplane clock feature to be able to use the generated backplane clock.
Configuration
: Allows the selection and configuration of the backplane
8 kHz clock that will be generated when enabled.
Clock Mode
: Allows the clock source selection. The default setting is
Internal
.
Enable
: Allows enabling the selected backplane clock.
Alarm Analysis
LOC
(Loss Of Clock): Indicates if the module is able (green) or unable
(red) to synchronize with the selected test clock.
Clock Mode
LAN WAN
Internal
: Internal clock of the unit (STRATUM 3). Internal is the only
available clock when 10GigE LAN transceiver mode is selected with
Frame
Analyzer
,
BERT
, or
RFC 2544
test.

External
: Clock from the connected
DS1/E1/2M
external clock signal (
For
IQS-8510G: EXT. CLK DS1/2M IN port; For IQS-8120NGE
/
IQS-8130NGE
and
IQS-8525
/
IQS-8535
:
AUX
port). Once the test is created, refer to
Clock
Synchronization

to complete the external clock settings. For
IQS-8120NGE and IQS-8130NGE,
External
is not available in Dual Test Set
one-way latency mode.
-
X
Recovered
: Live clock from the optical port input signal involved in the test.
Recovered is the only available clock when 10GigE
LAN
transceiver mode is
selected with Smart Loopback test. Recovered is only available for Smart
Loopback test.

Backplane
: 8 kHz clock from another module on the IQS-600. Note that the
other module must support the backplane clock feature and must be
enabled (refer to
on page 388 for more information).
