Use this procedure to initially equip and test a new Alcatel-Lucent 1665 DMX for a DS1 subshelf in an existing multishelf Digital Cross-Connect System (DCS) application.
Up to 12 DS1 subshelves are supported in a multishelf DCS application.
This procedure assumes that all hardwired installation and testing of the unequipped Alcatel-Lucent 1665 DMX shelves is done. It also assumes that power is applied to the shelves.
The basic purpose of this procedure is to:
Install and test system required circuit packs and software.
Install and test optional circuit packs that you want to install at initial installation.
Test the Alcatel-Lucent 1665 DMX for proper and alarm free operation before placing into the network.
Additional references are provided at the end of this procedure for provisioning optional system and circuit pack port parameters.
Important!
Some of the steps and procedures referenced in this procedure provide information on provisioning port parameters. If you provision parameters after installing each circuit pack, then you should NOT perform the part of the procedure in Step 13 to reset all provisionable parameters to default values.
Depending on local procedures, you may set the circuit pack and/or port parameters in this procedure, or reference the appropriate procedures in this document when you are ready to establish your network and service configurations.
A DS1 subshelf supports up to 4 pairs of LNW801 56DS1/E1 circuit packs in the Function slots (Growth slots not used) and one pair of LNW48/50/54/203 OC-12 packs in the Main slots. If other circuit packs types are installed, the system reports an unexpected CP type alarm. The LNW801 circuit packs are configured for DS1 ports. E1 interfaces are not supported in this release. The OC-12 ports on the main circuit packs must be configured as a unidirectional nonrevertive 1+1 OC-12 protection group.
The cross-connections on the DS1 subshelves are fixed and provide nonblocking access in the main shelf to all 224 DS1 signals in the subshelf.
You must log in as a Privileged user to complete this procedure.
Before you begin this procedure:
Refer to Laser safety and Electrostatic discharge in Chapter 1, Safety.
If not previously completed, install generic and WaveStar® CIT software on the PC. Refer to Procedure 14-1: Install software on the PC.
Obtain the work instructions for this procedure which state the quantity and type of circuit packs to be installed.
Verify that you have the proper type and code of circuit packs being installed.
If system and circuit pack port parameters are being set at this time, ensure you have a full set of work instructions detailing the values of the parameters being set.
It is suggested that you first install and test all the required circuit packs, perform the necessary system tests, reset all provisionable parameters to factory default values, then provision system and port parameters from values given in your work instructions.
Complete the following steps to initially equip and test a new Alcatel-Lucent 1665 DMX for a DS1 subshelf in multishelf Digital Cross-Connect System (DCS) applications.
1 |
Install SYSCTL circuit pack in the DS1 subshelf. Reference: Procedure 4-1: Install SYSCTL (LNW2) in new Alcatel-Lucent 1665 DMX shelf | ||
2 |
Connect personal computer and establish WaveStar® CIT session with the DS1 subshelf. Reference: Procedure 14-2: Connect Personal Computer (PC) and establish WaveStar® CIT session | ||
3 |
Install system software, if required. Reference: | ||
4 |
Important! The LNW48, LNW50, LNW54, or LNW203 OC-12 OLIU circuit packs are required in the Main slots at a DS1 subshelf. Install the required circuit packs in the Main slots at the DS1 subshelf. Reference: Procedure 4-2: Install OLIU circuit packs in Main slots | ||
5 |
Important! The system Timing Mode should be provisioned to Free Running to avoid Holdover alarms before adding the DS1 subshelf to the multishelf DCS system. The timing parameters for a subshelf are set automatically as part of the subshelf startup procedure. Select Configuration → Timing/Sync to provision the system Timing Mode to Free Running. Reference: Procedure 6-5: Network Element synchronization provisioning | ||
6 |
Install any required LNW801 56DS1/E1 circuit packs in the Function slots on DS1 subshelf. Reference: Procedure 4-6: Install DS3/EC1 circuit packs | ||
7 |
Provision DS1 ports, if required at this time and not already performed. Reference: Procedure 4-7: Provision DS3/EC1 circuit packs/ports for service | ||
8 |
Improperly-seated circuit packs or missing apparatus blanks may cause service hits on in-service systems. All slots in Alcatel-Lucent 1665 DMX must be equipped with fully-seated circuit packs or apparatus blanks to prevent service hits on in-service systems. Install 177D Apparatus Blanks or LNW98 circuit packs in any unused Function/Growth slots. Important! All slots in the Alcatel-Lucent 1665 DMX must be equipped with fully-seated circuit packs or apparatus blanks. | ||
9 |
Perform the LED test to verify that all LEDs are operating properly. Reference: Procedure 14-13: Perform LED test | ||
10 |
Perform local terminal transmission tests, if required. Reference: Procedure 14-9: Perform DS1/E1 transmission test | ||
11 |
Perform local facility transmission tests, if required. Reference: Procedure 14-9: Perform DS1/E1 transmission test | ||
12 |
Test protection switching function, if required. Reference: Procedure 14-12: Test function unit equipment protection switching | ||
13 |
Perform one of the following depending on whether or not you have already provisioned circuit packs and ports for service:
Result: You will be logged off the system during the controller reset and provisionable parameters will be set to factory default. 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. Holdover alarm may also occur since timing mode reverts back to External. If required to silence alarm, select Configuration → Timing/Sync and provision the system timing mode to Free Running. | ||

Add the DS1 subshelf to the existing multishelf DCS application, when required. Reference: Procedure 4-31: Add subshelf to multishelf Digital Cross-Connect System (DCS) application End of steps |
