what is the difference between ZAHO and ZYEF commands?
-ZAHO command is displaying active alarms. While ZYEF, it is an interrogating command status:
For ET card.
ZYEF:ET,et#; – This will display status of ET if its PCM failure or OK.
While ZAHO:ET,xx; – This will display current active alarm.
In a chain of BTS sites with one as a hub site,sometimes the hub site has pcm failure and OM is BL but we see the dependent sites are normal and working!!!!!!
– what BTS model are using? Is their transmission in the chain are the same?
