These controls are typical for all PIIC module types, except as noted.
• Use the Tx Symbol Clock PLL drop-down list to select Alarm, Fault, Mask, or Fault (Tx On).
•
Use the Input Signal Loss drop-down list to select Alarm, Fault, Mask, or Fault (Tx On).
•
Use the Rx Buffer Clock PLL drop-down list to select Alarm, Fault, or Mask.
•
Use the Rx Buffer Overflow / Underflow drop-down list to select Alarm, Fault, or Mask.
•
Valid for G.703 PIICs only: Use the Ext Clock Activity drop-down list to select Alarm, Fault,
Mask or Fault (Tx On). This indicates that the External Clock is selected by either the TxClock
or RxClock, but no clock is present on J8 | EXT REF.
•
Valid for G.703 PIICs only: Use the Ext Clock In Range drop-down list to select Alarm, Fault,
Mask or Fault (Tx On). This indicates that the External Clock is selected by either the TxClock
or RxClock, but the clock rate on J8 | EXT REF does not meet the rate expected by the
CDM-760.
• Valid for ASI PIICs only: Use the Tx Frame Lock drop-down list to select Alarm, Fault, Mask
or Fault (Tx On).
