Control
Overview
Alcatel-Lucent 1665 DMX provides extensive control features, accessible through a number of technician and operations system (OS) interfaces. In addition to accessing local Alcatel-Lucent 1665 DMX NEs through direct interfaces, technicians and OSs can use the operations features supported via the DCC in the optical signals to access remote NEs. Control functions are supported by the SYSCTL circuit pack.
Three-tiered operations interface
Alcatel-Lucent 1665 DMX maintenance procedures are built on three levels of system information and control. The first tier is provided by the LEDs, displays, and push-button switches located on the faceplate of the SYSCTL circuit pack. The second tier uses WaveStar® CIT to provision and retrieve detailed reports of performance monitoring, alarm and status, and system configuration for both local and remote NEs. The third tier uses the OS interfaces such as TL1 and TL1 over IAO LAN (TCP/IP or OSI) or CIT to monitor performance, gather alarm information, and configure the system. Also, the IAO LAN interfaces provisioned for TCP/IP support software download and provisionable database backup/restore via FTP.
SYSCTL faceplate
The faceplate of the SYSCTL circuit pack contains indicators that provide system-level information and control functions. The condition of the individual transmission circuit packs can be determined using faceplate LEDs.
The figure on the following page, shows the SYSCTL faceplate. There is a 35-segment numeric LED display and three push-button switches for Update/Initialize (UPD/INIT), ACO/test (ACO/TEST), and Select (SEL) for local operations.
LNW2 comes equipped with two removable Non-volatile Memory (NVM) cards that can also be ordered separately. The Alcatel-Lucent 1665 DMX shelf will only function properly when it is equipped with an LNW2 that contains two fully functioning NVM cards.
In addition to the Active and FAULT LED, there are also seven alarm/status LEDs on the SYSCTL faceplate, listed below. The FAULT LED is lit if the SYSCTL detects its own failure:

Embedded operations channel
Access and control extends beyond the local Alcatel-Lucent 1665 DMX to remote network elements via the SONET section data communications channel (DCC). Craft interface dialogs and operations messages are exchanged in the DCC overhead bytes on each OC-3, OC-12, OC-48, and OC-192 interface.
