C.3 Node Default Settings
to be disabled when they are providing services (when the default is set to FALSE users must remove
or disable the services first, then put the ports out of service), and whether to report loopback
conditions on Out-of-Service, Maintenance (OOS-MT) state ports.
•
Power Monitor settings—Set default voltage thresholds for the node.
•
Network settings—Set whether to prevent display of node IP addresses in CTC (applicable for all
users except Superusers); default gateway node type; whether to raise an alarm when the backplane
LAN cable is disconnected; and whether to display the IP address in the LCD in an editable mode
(in which you can change the IP address directly from LCD screen), to display the IP address on the
LCD as read-only, or to suppress display of the IP on the LCD entirely.
OSI settings—Set the Open System Interconnection (OSI) main setup, generic routing
•
encapsulation (GRE) tunnel default, the link access protocol on the D channel (LAP-D), the router
subnet, and the TID address resolution protocol (TARP) settings.
•
1+1 and Optimized 1+1 protection settings—Set whether or not protected circuits have bidirectional
switching, are revertive, and what the reversion time is; set optimized 1+1 detection, recovery, and
verify guard timer values.
Note
•
BLSR protection settings—Set whether BLSR-protected circuits are revertive, and what the
reversion time is, at both the ring and span levels.
Legal Disclaimer—Set the legal disclaimer that warns users at the login screen about the possible
•
legal or contractual ramifications of accessing equipment, systems, or networks without
authorization.
Security Grant Permissions—Set default user security levels for activating/reverting software, PM
•
data clearing, database restoring, and retrieving audit logs.
Security DataComm settings—Set default security settings for TCC Ethernet IP address and IP
•
netmask, and CTC backplane IP suppression; set secure mode on and secure mode locked (for
TCC2P cards only).
Note
•
Security Access settings—Set default security settings for LAN access, shell access, serial craft
access, element management system (EMS) access (including Internet Inter-Object Request Broker
Protocol [IIOP] listener port number), TL1 access, and Simple Network Management Protocol
(SNMP) access.
Security RADIUS settings—Set default RADIUS server settings for the accounting port number and
•
the authentication port number, and whether to enable the node as a final authenticator.

Optimized 1+1 supports three timers that ensure the correct state of the cards at key points
in card communication. A verification guard timer is used when a Force is issued, to ensure
that the far end has a chance to respond. A detection guard timer is used to ensure the
presence of an SF/SD condition before switching away from a card. A recover guard timer
ensures the absence of SF/SD prior to switching to a card. You can change the default
number of seconds before these timers expire by changing the NE default for the
corresponding timer to a value within its domain of allowable values.
The secure mode supported setting is not user-configurable; rather, it depends upon the presence
or absence of TCC2P cards on the node for its setting.
