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

This section highlights new features and functionality for Release 4.1.x. For detailed documentation of 
each of these features, consult the user documentation.

Release 4.1.3 adds SONET support for the DS3i-N-12 card, as specified herein. For DS3i-N-12 card 
features and specifications, refer to the Cisco ONS 15454 SDH Reference Manual, R4.1.x and R4.5.

The DS3i-N-12 card is not compatible with the DS3 or the DS3E card. There is no in-service upgrade 
path from DS3 or DS3E to DS3i-N-12. Plugging a DS3i-N-12 card into a slot provisioned for DS3 will 
result in an MEA. Plugging a DS3 card into a slot provisioned for DS3i-N-12 will result in an MEA.

The DS3i-N-12 card operates with either the XC10G or the XCVT card. Future cross connect cards will 
be supported as they become available.

The DS3i-N-12 card operates with either the TCC+ or the TCC2 as the shelf controller as long as the 
particular type of TCC card is supported with the particular software release. Future shelf controller 
cards will be supported as they become available.

Plugging a DS3i-N-12 card into a SONET chassis running a 4.0 or later software release that does not 
support the DS3i-N-12 will result in an MEA. On software releases prior to 4.0, the DS3i-N-12 card will 
continuously reboot without raising any alarm.

The following guidelines apply for circuit provisioning with the DS3i-N-12 card.

A circuit from a DS3i-N-12 port to a DS3 port cannot be provisioned.

A circuit from a DS3i-N-12 port on an ONS 15454 (SONET) node to a DS3i-N-12 port on another 
ONS 15454 node can be made.

A circuit from a DS3i-N-12 port on an ONS 15454 (SONET) node to a DS3i-N-12 port on an ONS 
15454 SDH node can be made, but there will be no end-to-end provisioning. The circuit must be 
provisioned in a two part process: The DS3i-N-12 to optical card is provisioned on the SONET side 
and the DS3i-N-12 to the corresponding SDH optical card is provisioned.

You are only allowed to create STS3C circuits from/to the DS3i-N-12 card.

There can only be four independent STS3C circuits provisioned from/to the DS3i-N-12 card.

The ports used in each of the STS3C circuits are 1, 2, and 3; 4, 5, and 6; 7, 8, and 9; 10, 11, and 12.

Each port on the DS3i-N-12 card can be provisioned independently in or out of service, but if less 
than three ports are used, the extra bandwidth is underutilized, because the STS3C will still be 
provisioned across the span cards.
