•
Default - Variable—Select this option if the ONS 15310-MA SDH nodes are on the same side of the
firewall as the CTC computer or if no firewall is used (default). This option sets the CTX listener
port to Port 57790. It can be used for access through a firewall if Port 57790 is open.
• Standard Constant—Select this option to use Port 683, the CORBA default port number, as the CTC
computer listener port.
•
Other Constant—If Port 683 is not used, enter the IIOP port provided by your administrator.
Unavailable ports are listed in the “Management Network Connectivity” chapter of the
Cisco ONS 15310-MA SDH Reference Manual .
Step 4 Click Apply . A warning appears telling you that the port change will apply during the next CTC login.
Step 5
Click OK .
Step 6 To access the ONS 15310-MA SDH using the IIOP port, log out of CTC by choosing Exit from the File
menu.
Step 7
Log back into CTC. See the “DLP-H29 Log into CTC” task on page 16-43 for instructions.
Step 8 Return to your originating procedure (NTP).
DLP-H45 Set Up External or Line Timing
Step 1 In the node view, click the Provisioning > Timing > General tabs.
Step 2
In the General Timing area, complete the following information:
• Timing Mode—Choose External if the ONS 15310-MA SDH derives its timing from a BITS source
wired to the port on the 15310; choose Line if timing is derived from the STM-M, E1-28, or E1-84
port. A third option, Mixed, allows you to set external and line timing references.
Note
Because Mixed timing can cause timing loops, Cisco does not recommend its use. Use this mode
with care.
• SSM Message Set—Choose a synchronization status messaging (SSM) message set. All
ONS 15310-MA SDH nodes can translate Generation 2 message sets, so choose Generation 2 if the
ONS 15310 is connected to other ONS 15310 nodes. Choose Generation 1 only when the ONS
15310 is connected to equipment that does not support Generation 2. If a node that has its SSM
Message Set set to Generation 1 receives a Generation 2 message, it maps the message down to the
next available Generation 1 message. The transit node clock (TNC) and ST3E become an ST3.
Purpose This task defines the external or line SDH timing source for the
ONS 15310-MA SDH.
