CP525 cMux User’s Manual Rev. 5.20.12 (3944)
STM-1/OC-3 present
Indicates if the module has been detected by the CP525.
Write to module
This box must be checked to allow the configuration file be written to the SFP module.
If the box is not checked the configuration file may still be edited without affecting the
module. If the box is checked the configuration file is written to the module every time
the
Apply
button is clicked.
Tx clock source
The transmitter clock may be internally generated, or derived from the received data
stream.
Frame type
Select SDH or SONET, respectively, according to the accessed network.
Payload FCS (Frame check sequence)
Check this box to enable FCS error detection.
Disable interface
Not available.
Scrambler
Tick this box to enable the module internal scrambler. Must be ticked to successfully
receive scrambled network data.
Ethernet flow control
A tick enables flow control of Ethernet data from the CP525 to the SFP module. Flow
control prevents data overflow in the SFP module buffer. Buffer overflow leads to data loss
that would go unnoticed until attempting to decode the data at the receiving end.
In the
Fault Propagation
field check boxes allow to select which network fault(s) shall cause
shut-down of the Ethernet data flow:
LOS
Loss of signal
AIS
Alarm indication signal
RDI_P
Remote defect indication
In the
Thresholds
field bit error rate measurements indicate an estimate of the network link
quality. The check boxes allow selection of pre-defined threshold BER values to raise alarms.
For further details refer to the vendor SFP user manual.
