TID Multiplexing: TID Multiplexing Troubleshooting

TID Multiplexing Troubleshooting

If an OSS is not getting a response from an NE, it can send a TL1 retrieve header 
command (

RTRV-HDR

) to determine if the problem is with the NE or with AI296. The 

parent connection on AI296 responds to 

RTRV-HDR

 commands that have the same TID 

as the one configured for the card.

Tip: For more information regarding TL1 commands, responses, and formats, refer 

to the Belcore document GR-833-CORE.

RTRV-HDR
