Front Panel Operation MN-CDM625
5–49
5.2.1.11.8 CONFIG: Mask  ROp (RAN Optimization) (FUTURE)
RAN Optimization Rx Alarm = Active
(Active,Masked) ()
Although selectable/viewable, this mask is reserved for the RAN Optimization option card which,
at present, is not supported. It will be supported in a future release.
5.2.1.11.9 CONFIG: Mask  BUC
Appendix F. CDM-625 ODU (TRANSCEIVER, BUC, LNB) OPERATION
BUC alarm = Active (Active,Mask)
Attach to Tx alarm = No (Yes,No)()
When using L-Band, a Block Up Converter (BUC) may be included in the system. A ‘smart’ BUC
may be monitored and/or controlled via the modem via FSK (Frequency-Shift Keying control).
For a modem in a 1:1 redundancy setup, you must customize the fault indications for the
physical setup.
5.2.1.11.10 CONFIG: Mask  LNB
Appendix F. CDM-625 ODU (TRANSCEIVER, BUC, LNB) OPERATION
LNB alarm = Active (Active,Mask)
Attach to Rx alarm = No (Yes,No)()
When using L-Band, a Low-Noise Block Down Converter (LNB) may be included in the system. It
cannot be monitored and/or controlled by the modem, except for the power supply values. For a
modem in a 1:1 redundancy setup, you must customize the fault indications for the physical setup.
5.2.1.11.11 CONFIG: Mask  CEX (G.703 Clock Extension mask)
G.703 Clock Extension = Active
(Active, Masked) ()
Use the
▲▼ arrow keys to select Active or Masked, and then press ENTER.
Selecting Active generates a CEX alarm if the G.703 Clock Extension mode is set to TxLock and
the input is lost or removed from the G.703 interface.
