New Features and Functionality
Network Time Protocol
The Network Time Protocol (NTP) feature enhances the SNTP (Simple Network Time Protocol)
functionality of the ONS 15327 for Release 3.3. Now NTP servers are supported. Previously, the ONS
15327 supported only an SNTP server.
Routing Improvements
Release 3.3 supports the ability to add a default route for connection to external systems. When the
default route is added to one node, it is then advertised to all other DCC connected ONS 15454s and
ONS 15327s.
Spanning Tree Control
Release 3.3 adds the ability to Turn Spanning Tree off for Ethernet circuits. You can disable or enable
spanning tree on a circuit-by-circuit basis on unstitched Ethernet cards in a point-to-point configuration.
This feature allows you to mix spanning tree protected circuits with unprotected circuits on the same
card, to reuse VLANS, and to set up two single-card E-series Ethernet cards on the same node to form
an intranode circuit.
AIS Off Mode for J1 Path Trace
In previous releases, when a J1 trace mismatch is detected the ONS 15327 inserts AIS path in the
timeslot. The AIS off mode feature will allow customers to choose between sending or not sending
AIS-P downstream from the TIM-P defect. When AIS-P is inserted downstream the likelihood of a traffic
outage increases. The AIS off mode feature does not require any special configurations other than J1
compatible modules. See the Cisco ONS 15327 User Documentation for details on J1 compatibility.
Orderwire Passthrough
Orderwire passthrough allows you to use Local/Express Orderwire between two ONS 15454 nodes that
each have the AIC card, but have intermediate nodes between them that have no AIC card installed. As
of Release 3.3 the ONS 15327 is supported for acting as an intermediate node in Orderwire passthrough.
Line Buildout
Release 3.3 allows setting the Line Buildout (LBO) distance for the ONS 15327 BITS out signal. This
setting is located in the Provisioning > Timing tabs. The setting is only applicable to the BITS Out signal
and has no effect on the BITS in signal.
Add Node Button
The Add Node button in CTC Release 3.3 allows you to easily add nodes to your CTC session view. The
Add Node button appears in the upper left corner of the CTC window in any view. For more information
on this feature, see Cisco ONS 15327 User Documentation, Release 3.3.
Span Upgrades
In Release 3.3, in-service span upgrades are supported.
