New Features and Functionality
Electrical IO Cards

When upgrading the software from Release 6.x.x to Release 7.x.x, the DS3 and EC1-12 cards fail to load
if the node name begins with the letters FL. Changing the node name resolves this issue.

TL1 Functionality
CSCeh88565
When the Cisco ONS 15600 is supporting 500 TL1 sessions and there is a sustained high level of
management traffic the active TSC might reset. This issue is visible when the Cisco ONS 15600 is
supporting 500 TL1 ENE logins to DCC-linked network nodes such as the Cisco ONS 15454. In a
laboratory test it was observed that an alarm flood (approximately 70000 alarm messages) in the network
would overload the active TSC and cause it to reset. The standby TSC transitions to active and the node
recovers. To avoid this issue configure TL1 sessions to throttle the amount of alarm data that is sent
across the management network. For example, when a TL1 session starts, the REPT^ALM and
REPT^EVT messages are allowed by default. The TL1 command “INH-MSG-ALL” will inhibit all
REPT-ALM and REPT^EVT autonomous messages from being transmitted. This issue is resolved in
Release 7.0.

The following feature has been added for Release 7.0.2.
Daylight Savings Time Support
With Release 7.0.2 CTC and TL1 display daylight savings time (DST) in keeping with the new DST rules
applicable from 2007 forward. As described in the change in energy policy for the United States of
America (USA), the DST start date will be the 2nd Sunday of March and the DST end date will be 1st
Sunday of November.

The following features were added for Release 7.0.
Server Trails
Release 7.0.x adds support for server trails. A server trail is a non-DCC link across a third-party network
that connects two CTC network domains. A server trail allows circuit provisioning when no DCC is
available. You can create server trails between any two optical or DS-3 ports. The end ports of a server
trail can be different types. Server trails are not allowed on DCC-enabled ports.
