Phase Lock Oscillator
4. Lamp Indications
Lamp indications for this circuit card are shown in the table below:
Note:
This lamp is effective when this card is mounted in TSWM0 of the IPX-U/IPX-UMG system. When this card
is mounted in ISWM, this lamp is not used.
LAMP NAME COLOR STATE
OPE Green Remains lit while this circuit card is in active state.
MJ Red
Lights when the following MJ fault has occurred:
• All of the clock supply routes have failed when the system operates as the clock
subordinate office
• 32.768 MHz output clock failure (including CLK card)
• 8 KHz output clock failure (including CLK card)
• Input Frame Pulse (FP) failure (FP is supplied by the SYNC card)
• Internal OSC (±5 ppm deviation) have failed when the system operates as the clock
source office
MN Red
Lights when the following MN fault has occurred:
• One or more (but not all) DTI/DCS clock supply routes have failed
• Drifting failure
• Internal OSC (±5 ppm deviation) failure
SYNC Green Remains lit while the system is synchronized with the network.
ICK Green Lights when the internal oscillator is operating normally.
CKPKG
Note
Green Lights when the CLK card in TSWM1 is in normal operation.
ALM0
Note
Red Lights when clock failure has occurred in the CLK card.
ALM1
Note
Red Lights when FH failure has occurred in the CLK card.
PALM Red Remains lit when the On-Board Power Supply is abnormal.
