Cisco Cisco ONS 15454 SONET Multiservice Provisioning Platform (MSPP) Notas de publicación

To be compatible with TL1 and DNS, all nodes must have valid names. Node names should contain 
alphanumeric characters or hyphens, but no special characters or spaces. 

When a TL1 session to a remote node (ENE) is established via a gateway node (GNE) and you have 
changed the node name of the ENE via either TL1, CTC or SNMP, then you must wait for about 30 
seconds to issue a TL1 command via the GNE. This delay is to permit the updates to propagate to all 
nodes in the network. During this transition, neither the old node name nor the new node name can be 
used in the TL1 session to access the ENE. This 30 second window may be reduced in a future release.

This section documents caveats resolved in Release 6.0.3. 

Some fan trays exhibit high electrical noise which causes communication loss between the fan tray and 
the controller card.  Eventually, this causes the controller card to reboot. The noise is proportional to the 
voltage level of the shelf and inversely proportional to the speed of the fans.

Workaround: Allow the fan trays to run at high speeds. There is considerable reduction in the noise. 
This issue is resoved in 6.03, 7.05, and 7.23.

TCCs intermittently restart. Noise in the fan tray that occurs during normal operation causes the TCC 
card to reset. 

Split route circuits on some FC_MR-4 cards will take some errors at -5C to +10C ambient temperatures. 
This issue is resolved in Releases 6.0.1, 6.1, and 7.0. 

In a configuration with OC-48 Any Slot cards and an STS-24c circuit, provisioned between G1000-4 
cards with traffic going over the OC-48 span, extracting the G1000-4 card at one end of the STS-24c 
circuit before deleting the circuit will result in a traffic hit on all existing SONET circuits defined over 
that same span. This only occurs when the STS-24c is provisioned on timeslot 25.
