Important!
This is not a standalone procedure. Perform this procedure only as directed by Procedure 9-9: Establish subtending low-speed UPSR/BLSR.
Important!
This procedure assumes that the subtending ring is established by interconnecting Alcatel-Lucent 1665 DMX nodes using a Function/Growth slot at the host Alcatel-Lucent 1665 DMX node and the OC-48 Main/Function/Growth slot pair of the Alcatel-Lucent 1665 DMX nodes in the subtending ring.
Ignore all alarms until procedure is complete.
Complete the following steps to establish a subtending low-speed OC-48 2-fiber BLSR. (Refer to the example in Figure 9-10, Subtending 2-fiber BLSR example and 2-fiber bidirectional line switched ring worksheet at the end of this procedure when performing this procedure.)

From your work instructions, determine the network configuration. Refer to Figure 9-10, Subtending 2-fiber BLSR example for an example. If possible, make a sketch of the existing network and the required subtending ring connections. If required, select the Administration → OSI Neighbor Map command at the host Alcatel-Lucent 1665 DMX node and note the NEs connected to Main 1 and Main 2. Access each NE identified, select the Administration → OSI Neighbor Map command, and note the NEs connected to Main 1 and Main 2. Repeat this step until the network can be sketched. | ||||||
2 |
Important! Two or more shelves in the same network cannot have the same TID. Using the work instructions and office records, verify that no duplicate TID settings exist between the nodes in the existing network and the subtending ring. If duplicate TID settings exist, determine new settings and at each site with duplicate TID settings, select Administration → Set TID from the System View menu, and enter new TID settings. Reference: Procedure 7-11: Set/change system TID | ||||||
3 |
If required, modify the network service access point (NSAP) address and/or enable Level 2 routing capabilities at the host Alcatel-Lucent 1665 DMX node and the nodes in the subtending ring. Reference: Procedure 7-13: Provision network layer 3 parameters | ||||||

Important! When the Main slot pair is equipped with LNW26B OC-48 OLIU circuit packs, low-speed OC-48 BLSRs are only supported in slot pair D1 and D2 or G1 and G2 only. Alcatel-Lucent 1665 DMX supports up to two subtending BLSRs. At the host Alcatel-Lucent 1665 DMX node, refer to DMX Node 5 in Figure 9-10, Subtending 2-fiber BLSR example, install the OLIU circuit packs in the appropriate Function/Growth slot pair (A1 and A2, B1 and B2, C1 and C2, D1 and D2, or G1 and G2). Important! If the work instructions or office records do not specify OLIU types, refer to Alcatel-Lucent 1665 Data Multiplexer (DMX) Applications and Planning Guide, 365-372-300, for a description of OLIU circuit packs and applications. Optical line power measurements and/or office records must be used to verify that the span length can be supported. The subtending ring connections to the host Alcatel-Lucent 1665 DMX node must be in two slots in the same Function/Growth group (for example: A1 and A2.) Reference: Procedure 4-3: Install OLIU circuit packs in Function slots | ||||||
5 |
Important! If OSI over DCC is enabled for ports, an inconsistent DCC values alarm is reported when the ports are looped back. If required at the host Alcatel-Lucent 1665 DMX node, clear the inconsistent DCC values alarm by disabling OSI over DCC for the required ports. From the System View menu, select Configuration → DCC Terminations and disable OSI Over DCC for the required DCC ports. Reference: Procedure 6-4: Provision DCC terminations | ||||||
6 |
Important! The Application parameter of the low-speed OC-n port pairs being connected must be provisioned 2F BLSR. Up to 15 BLSR protection groups may be supported by a single network element when the Main slots are equipped with Very Large Fabric LNW59, LNW82, or LNW504 OLIU circuit packs. From the System View menu at the host Alcatel-Lucent 1665 DMX node, select Configuration → Equipment, select the required low-speed OC-n ports, and provision the port parameters according to the work instructions. Reference: Procedure 4-4: Provision OLIU circuit packs/ports for service | ||||||
7 |
At the host Alcatel-Lucent 1665 DMX node, verify that the low-speed OC-n ports were provisioned correctly using the View → Equipment command. | ||||||

From the system view at the host Alcatel-Lucent 1665 DMX node,

Important! 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. From the System View menu, select Configuration → DCC Terminations and provision the DCC terminations for the required DCC ports according to the work instructions. Result: If OSI over DCC is enabled, an inconsistent DCC values alarm will occur if the OC-n ports are looped back. Reference: Procedure 6-4: Provision DCC terminations | ||||||
12 |
From the System View menu at the host Alcatel-Lucent 1665 DMX node, select View → DCC Terminations and verify that the DCC terminations were provisioned correctly. | ||||||
13 |
At each node in the subtending ring, provision the required Main/Function/Growth ports, 2-fiber BLSR protection group, DCC terminations, synchronization, and remote NE status functions according to the work instructions.
| ||||||
14 |
Beginning at the host Alcatel-Lucent 1665 DMX node, connect the fibers between the required low-speed OC-n port in Function/Growth slot 1 and the required OC-n port in Main/Function/Growth slot 2 at the adjacent node and verify the integrity of the optical span being established. Reference: Refer to Figure 9-10, Subtending 2-fiber BLSR example when connecting fibers. The following connections are required at the host Alcatel-Lucent 1665 DMX node:
Reference: Procedure 14-4: Perform connection and verification of optical facility | ||||||
15 |
Perform end-to-end optical line test. Reference:
| ||||||
16 |
Repeat Step 14 and Step 15 for each optical span in the subtending 2-fiber BLSR. Continue around the subtending ring in the same direction until all nodes are connected. Refer to the example at the end of the procedure. | ||||||
17 |
| ||||||
18 |
At the host Alcatel-Lucent 1665 DMX node, verify 2-fiber BLSR protection switching:
Repeat this step at each node in the subtending 2-fiber BLSR (refer to the 2-fiber BLSR worksheet at the end of the procedure) to verify protection switching. | ||||||
19 |
At each node in the subtending ring, click the Alarm List button and verify that no alarms are present. If required, clear any alarms that are present. Reference: Alcatel-Lucent 1665 Data Multiplexer (DMX) Alarm Messages and Trouble Clearing Guide, 365-372-302 | ||||||

Important! Establishing service requires that the proper slots in each terminating node be properly equipped with the correct circuit pack(s) for the type of service being established. It also requires numerous cross-connections in each of the nodes representing the path of the required service. Additionally, transmission tests should be performed to verify the continuity and quality of the established circuit. The subtending ring is now ready for initial service to be established.
