8.1  CTC Software Delivery Methods

ONS 15454 SDH provisioning and administration is performed using the CTC software. CTC is a Java application that is installed in two locations; CTC is stored on the TCC2 card and it is downloaded to your workstation the first time you log into the ONS 15454 SDH with a new software release.

8.1.1  CTC Software Installed on the TCC2 Card

CTC software is preloaded on the ONS 15454 SDH TCC2 card; therefore, you do not need to install software on the TCC2 cards. When a new CTC software version is released, follow procedures in the Cisco ONS 15454 SDH Software Upgrade Guide to upgrade the ONS 15454 SDH software on the TCC2 cards.

When you upgrade CTC software, the TCC2 cards store the new CTC version as the protect CTC version. When you activate the new CTC software, the TCC2 cards store the older CTC version as the protect CTC version, and the newer CTC release becomes the working version. You can view the software versions that are installed on an ONS 15454 SDH by selecting the Maintenance > Software tabs in node view (Figure 8-1).

Figure 8-1 CTC Software Versions, Node View

Select the Maintenance > Software tabs in network view to display the software versions installed on all the network nodes (Figure 8-2).

Figure 8-2 CTC Software Versions, Network View

8.1.2  CTC Software Installed on the PC or UNIX Workstation

CTC software is downloaded from the TCC2 cards and installed on your computer automatically after you connect to the ONS 15454 SDH with a new software release for the first time. Downloading the CTC software files automatically ensures that your computer is running the same CTC software version as the TCC2 cards you are accessing. The computer CTC software files are stored in the temporary directory designated by your computer's operating system. You can use the Delete CTC Cache button to remove files stored in the temporary directory. If the files are deleted, they download the next time you connect to an ONS 15454 SDH. Downloading the Java archive files, called "JAR" files, for CTC takes several minutes depending on the bandwidth of the connection between your workstation and the ONS 15454 SDH. For example, JAR files downloaded from a modem or a data communication channel (DCC) network link require more time than JAR files downloaded over a LAN connection.

8.2  CTC Installation Overview

To connect to an ONS 15454 SDH using CTC, you enter the ONS 15454 SDH IP address in the URL field of Netscape Communicator or Microsoft Internet Explorer. After connecting to an ONS 15454 SDH, the following occurs automatically:

1. A CTC launcher applet is downloaded from the TCC2 card to your computer.

2. The launcher determines whether your computer has a CTC release matching the release on the ONS 15454 SDH TCC2 card.

3. If the computer does not have CTC installed, or if the installed release is older than the TCC2 card's version, the launcher downloads the CTC program files from the TCC2 card.

4. The launcher starts CTC. The CTC session is separate from the web browser session, so the web browser is no longer needed. Always log into nodes having the latest software release. If you log into an ONS 15454 SDH that is connected to ONS 15454 SDHs with older versions of CTC, CTC files are downloaded automatically to enable you to interact with those nodes. The CTC file download occurs only when necessary, such as during your first login. You cannot interact with nodes on the network that have a software version later than the node that you used to launch CTC.

Each ONS 15454 SDH can handle up to five concurrent CTC sessions. CTC performance can vary, depending upon the volume of activity in each session, network bandwidth, and TCC2 card load.

---

Note The TCC2 card requires Software R4.0 or later.

---

8.3  PC and UNIX Workstation Requirements

To use CTC in the ONS 15454 SDH, your computer must have a web browser with the correct Java Runtime Environment (JRE) installed. The correct JRE for each CTC software release is included on the ONS 15454 SDH software CD and the ONS 15454 SDH documentation CD. If you are running multiple CTC software releases on a network, the JRE installed on the computer must be compatible with the different software releases.

You can change the JRE version on the Preferences dialog box JRE tab. When you change the JRE version on the JRE tab, you must exit and restart CTC for the new JRE version to take effect.Table 8-1 shows JRE compatibility with ONS software releases.

Table 8-1 JRE Compatibility

ONS Software Release	JRE 1.2.2 Compatible	JRE 1.3 Compatible	JRE 1.4 Compatible
ONS 15454 SDH Release 3.3	Yes	Yes	No

8.5  CTC Window

The CTC window appears after you log into an ONS 15454 SDH (Figure 8-3). The window includes a menu bar, toolbar, and a top and bottom pane. The top pane provides status information about the selected objects and a graphic of the current view. The bottom pane provides tabs and subtabs to view ONS 15454 SDH information and perform ONS 15454 SDH provisioning and maintenance. From this window you can display three ONS 15454 SDH views: network, node, and card.

Figure 8-3 Node View (Default Login View)

8.5.1  Node View

Node view, shown in Figure 8-3, is the first view open after you log into an ONS 15454 SDH. The login node is the first node shown, and it is the "home view" for the session. Node view allows you to view and manage one ONS 15454 SDH node. The status area shows the node name; IP address; session boot date and time; number of Critical (CR), Major (MJ), and Minor (MN) alarms; the name of the current logged-in user; and the security level of the user; software version; and the network element default setup.

8.5.1.1  CTC Card Colors

The graphic area of the CTC window depicts the ONS 15454 SDH shelf assembly. The colors of the cards in the graphic reflect the real-time status of the physical card and slot (Table 8-4).

Table 8-4 Node View Card Colors 

Card Color	Status
Gray	Slot is not provisioned; no card is installed.
Violet	Slot is provisioned; no card is installed.
White	Slot is provisioned; a functioning card is installed.
Yellow	Slot is provisioned; a Minor alarm condition exists.
Orange	Slot is provisioned; a Major alarm condition exists.
Red	Slot is provisioned; a Critical alarm exists.

The colors of the Front Mount Electrical Connection (FMEC) cards reflect the real-time status of the physical FMEC cards. Table 8-5 lists the FMEC card colors. The FMEC ports shown in CTC do not change color.

---

Note You cannot preprovision FMECs.

---

Table 8-5 Node View FMEC Color

Upper Shelf FMEC Color	Status
White	Functioning card is installed.
Yellow	Minor alarm condition exists.
Orange (Amber)	Major alarm condition exists.
Red	Critical alarm exists.

Ports can be assigned one of four states, OOS, IS, OOS-AINS, or OOS-MT. The color of the port in both card and node view indicates the port state. Table 8-6 lists the port colors and their states.

Table 8-6 Node View Card Port Colors 

Port Color	State	Description
Gray	OOS	Port is out of service; no signal is transmitted. Loopbacks are not allowed in this state.
Violet	OOS-AINS	Port is in an out of service, auto-inservice state; alarm reporting is suppressed, but traffic is carried and loopbacks are allowed. Raised fault conditions, whether or not their alarms are reported, can be retrieved on the CTC Conditions tab. The AINS port will automatically transition to IS when a signal is received for the length of time provisioned in the soak field.
Cyan (Blue)	OOS-MT	Port is in an out of service, maintenance state. The maintenance state does not interrupt traffic flow. Traffic is carried but loopbacks are allowed and alarm reporting is suppressed. Raised fault conditions, whether or not their alarms are reported, can be retrieved on the CTC Conditions tab. Use OOS-MT for testing or to suppress alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete.
Green	IS	Port is in service. The port transmits a signal and displays alarms; loopbacks are not allowed.

The wording on a lower-shelf card in node view shows the state of a card (Active, Standby, Loading, or Not Provisioned). Table 8-7 lists the card states.

Table 8-7 Node View Card States

Lower Shelf Card State	Description
Sty	Card is in standby.
Act	Card is active.
NP	Card is not present.
Ldg	Card is resetting.

The graphics on a port in node view show the state of a port (diagonal lines or loop graphics). Table 8-8 lists the port graphic and their description.

Table 8-8 Node View Port Graphics 

Lower Shelf Port Graphics	Description
Multiple diagonal lines on port	Port is in service and card was reset.
Loop graphic on port	Port is in service and has a loopback provisioned in Card View > Maintenance > Loopback tabs.

8.5.1.2  Node View Card Shortcuts

If you move your mouse over cards in the graphic, popups display additional information about the card including the card type; the card status (active or standby); the type of alarm, such as Critical, Major, and Minor (if any); and the alarm profile used by the card. Right-click a card to reveal a shortcut menu, which you can use to open, reset, or delete a card. Right-click a slot to preprovision a card (that is, provision a slot before installing the card).

8.5.1.3  Node View Tabs

Table 8-9 lists the tabs and subtabs available in the node view.

8.5.2  Network View

Network view allows you to view and manage ONS 15454 SDHs that have DCC connections to the node that you logged into and any login node groups you selected (Figure 8-4).

Figure 8-4 Network in CTC Network View

---

Note Nodes with DCC connections to the login node do not appear if you checked Disable Network Discovery check box in the Login dialog box.

---

The graphic area displays a background image with colored ONS 15454 SDH icons. A Superuser can set up the logical network view feature, which enables each user to see the same network view.

The lines show DCC connections between the nodes. DCC connections can be green (active) or gray (fail). The lines can also be solid (circuits can be routed through this link) or dashed (circuits cannot be routed through this link).

There are four possible combinations for the appearance of DCCs: green/solid, green/dashed, gray/solid, or gray/dashed. DCC appearance corresponds to the following states: active/routable, active/nonroutable, failed/routable, or failed/nonroutable. Circuit provisioning uses active/routable links. Selecting a node or span in the graphic area displays information about the node and span in the status area.

The color of a node in network view, shown in Table 8-10, indicates the node alarm status.

Table 8-10 Node Status Shown in Network View 

Color	Alarm Status
Green	No alarms
Yellow	Minor alarms
Orange	Major alarms
Red	Critical alarms
Gray with Unknown#	Node initializing for the first time (CTC displays Unknown# because CTC has not discovered the name of the node yet)

Table 8-11 lists the tabs and subtabs available in network view.

8.5.3  Card View

Card view provides information about individual ONS 15454 SDH cards (Figure 8-5). Use this window to perform card-specific maintenance and provisioning. A graphic showing the ports on the card is shown in the graphic area. The status area displays the node name, slot, number of alarms, card type, equipment type, and the card status (active or standby), card state (IS, OOS, OOS-AINS, or OOS-MT), or port state (IS, OOS, OOS-AINS, or OOS-MT). The information that appears and the actions you can perform depend on the card.

Figure 8-5 Card View

---

Note CTC provides a card view for all ONS 15454 SDH cards except the TCC2, XC10G, XC-VXL-10G, and XC-VXL-2.5G cards. Provisioning for these common control cards occurs at the node view; therefore, no card view is necessary.

---

Use the card view tabs and subtabs, shown in Table 8-12, to provision and manage the ONS 15454 SDH. The subtabs, fields, and information shown under each tab depend on the card type selected. The Performance tab is not available for the AIC-I card.

8.6  TCC2 Card Reset

You can reset the ONS 15454 SDH TCC2 card by using CTC (a soft reset) or by physically reseating a TCC2 card (a hard reset). A soft reset reboots the TCC2 card and reloads the operating system and the application software. Additionally, a hard reset temporarily removes power from the TCC2 card and clears all buffer memory.

You can apply a soft reset from CTC to either an active or standby TCC2 card without affecting traffic. If you need to perform a hard reset on an active TCC2 card, put the TCC2 card into standby mode first by performing a soft reset.

---

Note When a CTC reset is performed on an active TCC2 card, the AIC-I card goes through an initialization process and also resets because the AIC-I card is controlled by the active TCC2.

---

8.7  TCC2 Card Database

When dual TCC2 cards are installed in the ONS 15454 SDH, each TCC2 card hosts a separate database; therefore, the protect card's database is available if the database on the working TCC2 fails. You can also store a backup version of the database on the workstation running CTC. This operation should be part of a regular ONS 15454 SDH maintenance program at approximately weekly intervals, and should also be completed when preparing an ONS 15454 SDH for a pending natural disaster, such as a flood or fire.

---

Note The following parameters are not backed up and restored: node name, IP address, mask and gateway, and Internet Inter-ORB Protocol (IIOP) port. If you change the node name and then restore a backed up database with a different node name, the circuits map to the new node name. Cisco recommends keeping a record of the old and new node names.

---

8.8  Software Revert

When you click the Activate button after a software upgrade, the TCC2 copies the current working database and saves it in a reserved location in the TCC2 flash memory. If you later need to revert to the original working software load from the protect software load, the saved database installs automatically. You do not need to restore the database manually or recreate circuits.

---

Note The TCC2 card does not carry any software earlier than Software R4.0. You will not be able to revert to a software release earlier than Software R4.0 with TCC2 cards installed.

---

The revert feature is useful if a maintenance window closes while you are upgrading CTC software. You can revert to the protect software load without losing traffic. When the next maintenance window opens, complete the upgrade and activate the new software load.

Circuits created and provisioning done after a software load is activated (upgraded to a higher software release) do not reinstate with a revert (for example, 4.0 to 3.4). The database configuration at the time of activation is reinstated after a revert. This does not apply to maintenance reverts (for example, 4.0.2 to 4.0.1), because maintenance releases use the same database.
