Procedure 6-4: Provision DCC terminations
Overview
 |
NOTICE Service-disruption hazard |
Changing the DCC termination parameters may affect system operations.
Do not change the DCC termination parameters on an in-service system unless you are directed to do so from another procedure.
Use this procedure to provision the DCC termination parameters for an OC-N port.
Important!
The DCC termination parameters are generally provisioned when the system/optical span is integrated into a network.
Before you begin
Prior to performing this procedure,
-
Refer to Before you begin and Required equipment in this chapter.
-
Verify that the work instructions specify the OC-N port address and the required DCC termination parameter settings.
Steps
Perform the following steps to provision the DCC termination parameters for an OC-N port.
1 |
Using the work instructions, determine whether OSI over DCC or IP over DCC is to be provisioned for the required OC-N port.
| ||||||
2 |
From the System View menu, select Administration → Data Communications. Result: The Data Communications window opens. | ||||||
3 |
Click on the TCP/IP tab and select DCC-ALL from the Port AID: drop-down menu. | ||||||
4 |
Important! When IP over DCC is enabled for DCC ports, each DCC port does not require a unique IP address. IP over DCC interfaces are also referred to as unnumbered lines. Although each unnumbered line does not have a unique IP address, the network element must have the TCP/IP function enabled for the Port AID DCC-ALL and an IP address must be assigned. The IP address assigned to the DCC-ALL AID is used as the router ID for unnumbered lines. For DCC links that require the local network element and the far-end network element to be in the same subnet, the DCC-ALL AID of the local network element must have an IP address that is in the same subnet as the IP address of the far-end network element. Enable the TCP/IP Function parameter, provision the IP Address according to your work instructions, and provision the IP Subnet Mask to be 255.255.255.255. (When your Port AID is DCC-ALL, your IP subnet mask must be 255.255.255.255.) Click Apply. Result: A WaveStar® CIT Warning appears stating that executing this command will cause the system view to close and may cause the system to reset, then asks you to confirm executing this command. | ||||||
5 |
Click Yes to execute the command. Result: The WaveStar® CIT disconnects from the network element. A flashing b in the IND display on the SYSCTL indicates that a boot is in progress. During the boot, the b may extinguish for up to 20 seconds and then resume flashing. If automatic synchronization is unsuccessful, the date and time must be reset manually. If required, refer to Procedure 7-10: Set date and time. | ||||||
6 |
Re-establish the log in session to the network element. Reference: Procedure 14-2: Connect Personal Computer (PC) and establish WaveStar® CIT session | ||||||
7 |
From the System View menu, select Configuration → DCC Terminations. Result: The Configure DCC Terminations window opens. | ||||||
8 |
Select the required DCC Port being provisioned from the Port AID: drop-down menu. | ||||||
9 |
Important! The DCC Channel Parameters are generally provisioned when the system/optical span is integrated into a network and should not be changed unless you are reconfiguring the network and have been directed to do so. Provision the DCC Channel Parameters according to the work instructions and click Apply. Important! The LAPD Role parameter is not applicable if IP Over DCC is enabled. If OSI Over DCC is enabled, the LAPD Role parameter must be provisioned differently at each end of an optical span. For example, if the LAPD Role parameter is provisioned to user-side at one end of an optical span, then the LAPD Role parameter must be provisioned network-side at the other end of the optical span. | ||||||

If required, repeat Step 8 and Step 9 to provision other DCC ports; otherwise, click Close to exit. End of steps |
