C LASSIFICATION OF RUNNING INFORMATION

The running information of ZXG10-BTS (V1A) mainly comes from the panel indicators of OMU, TRU and other modules. Flashing of the indicators means differently, from which the running status of the equipment can be determined.

1. OMU

There are four indicators on the OMU panel, which, from top downwards, are power supply indicator, alarm indicator, running indicator, and active/standby indicator. The meanings of the combination statuses of the panel indicators are shown in Table 3-1.

Table 3-1 Names and meanings of the OMU indicators

Indicated status Power supply

The board not powered on Normally off Normally off Normally off Normally off

The board powered on Normally on X X X

BOOT starting Normally on Normally off 4 Hz flashing Normally off

Active status Normally on X X Normally on

Standby status Normally on X X Normally off

Process initially started Normally on Normally on Normally on Normally on Fault of the 4M or 8K

clock Normally on Normally on 1 Hz flashing X

LAPD link disconnected Normally on 1 Hz flashing 1 Hz flashing Normally on System initialization

status Normally on 4 Hz flashing 4 Hz flashing Normally on

File downloading Normally on 1 Hz flashing 4 Hz flashing Normally on

Note: X means “the indicator can be in any status”.

2. TRU

There are five indicators on the TRU board, i.e., power supply indicator, alarm indicator, running indicator, status indicator ST1 and status indicator ST2 from top downwards. Meanings of combinations of the panel indicators are shown in Table 3-2.

Table 3-2 Names and meanings of the TRU indicators

Indicated status Power supply

BOOT starting Normally on Normally

4Hz flash X X

Process initially started Normally on Normally on

Normally on X X

Fault of 4M or 8K clock Normally on Normally on

1Hz flashing X X

LAPD link disconnected Normally on 1Hz flash 1Hz flashing X X

HDLC link disconnected Normally on 4Hz flash 1Hz flash X X

System initialization status Normally on 4Hz flashing

1) X means “the indicator can be in any status ”.

2) The priority sequence of the indicators in working status is shown as follows: the priority gradually decreases from top downwards, i.e., “fault of 4M or 8K clock ----LAPD link disconnected ----HDLC link disconnected ----file downloading ----system initialization status”

3) ST1: Status indicator 1.If it is normally on, it means that this TRU is the carrier shelf where the BCCH channel is located. If it is normally off, it means that this TRU is the carrier shelf where the non-BCCH channel is located.

4) ST2: Status indicator 2.It is reserved in design, and not used in actual running.

3. BIE

There are four indicators on the BIE panel, i.e., power supply indicator, alarm indicator, running indicator, and active/standby indicator from top downwards. Meanings of combinations of the panel indicators are shown in Table 3-3.

4. EBIE

There are four indicators on the EBIE panel, which are, in turn from the top down, power supply indicator, alarm indicator, running indicator and active/standby indicator. Meanings of combinations of the panel indicators are shown in Table 3-4

5. CKU

There are five indicators on the CKU board, i.e., power supply indicator, alarm indicator, running indicator, active/standby indicator and phase lock indicator from top downwards. Meanings of combinations of the panel indicators are shown in Table 3-5.
