Cisco Bug: CSCzr00951 - ASI Outputs not muted on NIT update
Feb 03, 2012
- Digital Receivers/Decoders
Known Affected Releases
Symptom: An RF carrier is deleted from the NIT. MTRs with ASI outputs configured to use inband mode Apply or inband mode Uplink are expected to mute if they are configured to decombine a transport that appears in the deleted carrier. However, if the NIT update is received before the affected carrier is removed from broadcast, MTRs do not mute affected ASI outputs as expected. Conditions: Typical scenario: The RF carrier is being assigned a different transport ID or is to be deleted from the network. Example: 1. Configure MTR ASI Outputs in Apply/Uplink modes with CTID that belong to Carrier ID currently presented in NIT. 2. MTR RF input receiving this carrier must also be in Apply or Uplink mode. 3. Verify outputs are not muted and output a valid decombined stream 4. Change the NIT to remove the RF carrier used by outputs above or change the transport ID of the RF carrier Expected result: The MTR raises a Carrier ID Lost alarm and mutes ASI outputs using using content from the affected RF carrier. Actual result: The change in the NIT has no effect on ASI outputs and there is no alarm generated.
