SPVC-IE Signalling 
Type
Allows the user to signal out or terminate the soft permanent virtual 
circuit (SPVC). Select one of the following from the pull-down 
menu:
AnnexC+ (default) – Indicates that the SPVC-IE signalling first 
attempt will be accomplished with the PNNI 1.0 Annex C based 
SPVC signalling. If the call is rejected with the release cause of #88 
(Incompatible destination), the signalling will retry the same path 
using Addendum af-cs-0127 SPVC-IE support.
Addendum 127 – Indicates that the SPVC-IE signalling is always 
based on Addendum af-cs-0127 SPVC-IE support.
Template (Optional) Saves these settings as a template to configure another 
logical port with similar options. To create a template, check the 
box. Clear the box (default) if you do not wish to save the settings 
as a template.

Name link state advertisements (LSAs) will be advertised only if 
the logical port state remains “Down” for the specified minimum 
time. Enter a number of seconds (0-3600) for the minimum time. 
The default is 10 seconds.
