Multi-level operations
Overview
The following figure shows the multiple levels of operations procedures for Alcatel-Lucent 1850 TSS-5. The Alcatel-Lucent 1850 TSS-5 operations procedures are built on three levels of system information and control, spanning operations needs from summary-level status to detailed reporting. Different software is used and different features are available, depending on whether SONET/SDH (VLNC2, VLNC50, VLNC52, VLNC55, VLNC64), PDH (VLNC50, VLNC52, VLNC55, VLNC60, VLNC61, VLNC62, VLNC64) or Ethernet (VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64) operations are involved.
Example
The following figure, shows the multi-level operations procedures for Alcatel-Lucent 1850 TSS-5. The Alcatel-Lucent 1850 TSS-5 operations procedures are built on three levels of system information and control, from on-site indicators and switches, to remote methods for status reporting and control.
Figure 5-1: Multi-layered operations
SYSCTL, VLNC50/VLNC52/VLNC55, and VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 faceplate (operations level 1)
When a SYSCTL circuit pack is installed, office alarms are provided by a set of discrete relays that control office visual alarms. Separate relays handle critical/major alarms (CR/MJ) and minor (MN) alarms. These relays are located on the access panel at the right of the wall-mount shelf, or at the rear of the rack-mount shelf.
The first operations tier consists of light-emitting diodes (LEDs) and push buttons on the SYSCTL circuit pack faceplate, and LEDs on the VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit pack faceplate. These allow routine tasks and diagnostics to be performed without a craft interface terminal (CIT) or any test equipment. The SYSCTL circuit pack faceplate provides system-level alarm and status information for the local and remote terminals. The circuit pack faceplate FAULT LEDs allow fast and easy fault isolation to a particular circuit pack.
Miscellaneous discretes
Miscellaneous discretes are often referred to as "environmental alarms". Access to the Miscellaneous Discrete Inputs (MDIs) and Miscellaneous Discrete Outputs (MDOs) is via the VLIU.
The following SYSCTL MDIs/MDOs are managed via the TL1 or the WaveStar® CIT:
When a SYSCTL circuit pack is not installed, and the shelf is operating with VLNC4x circuit packs, a physical alarm output is available on the Miscellaneous Discrete Output connection MDO for that slot.
The following VLNC42B MDIs/MDO are managed via the WebGUI:
-
4 MDIs
-
1 MDO
Physically, the MDO is a normally open set of contacts; it is open in the event of a power failure or pack pull. The state is controlled by software.
Note:
The MDI/MDO housekeeping alarms are only available when the VLNC42B is in T-MPLS mode.
SYSCTL
The SYSCTL faceplate LEDs show local system information. The highest active alarm level is shown by the red LEDs for CR and MJ alarms. Yellow LEDs are shown for MN and ABN alarms. A green PWR ON LED shows that the power is on and the terminal is receiving a −48 VDC or +24 VDC source.
The Update/Initialize (UPD/INIT) button addresses the local system. The recessed UPD/INIT button serves several functions during installation and circuit pack replacement. During the first 10 seconds after powering up the SYSCTL circuit pack, depressing this button initializes the nonvolatile memory with provisioning and state information. Secondly, after removing a circuit pack or PTM, depressing this button updates the system equipment list to show the slot or signal is now unequipped.
The SYSCTL circuit pack faceplate's remote display functions serve the single-ended maintenance needs of access transport applications. When any alarm or status condition exists at a remote Alcatel-Lucent 1850 TSS-5 shelf, that alarm can be viewed in the Alarm List on the WaveStar® CIT.
Table 5-1, SYSCTL circuit pack faceplate LEDs details the various LEDs and push-button switches and describes their functions.

VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64
When Alcatel-Lucent 1850 TSS-5 is equipped with only a VLNC40/42/42B circuit pack, it operates as an Ethernet aggregator. When the shelf is equipped only with a VLNC60, VLNC61, VLNC62, or VLNC64 circuit pack, it operates as an Ethernet backhaul device for T1/E1 pseudowires (VLNC60/VLNC61/VLNC62/VLNC64), or data from ML-PPP sessions (VLNC60/61/62). If the shelf is equipped with two circuit packs, it can perform two functions. In these applications, it is not functioning as a SONET or SDH network element. The VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 faceplate LEDs show the state of the circuit packs.
Table 5-2, VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 faceplate LEDs details the various LEDs and describes their functions.

Local craft interfaces (operations level 2)
An on-site craft person can connect a local terminal or PC to the Alcatel-Lucent 1850 TSS-5 for administrative access. This administrative access can be to the CIT/TL1 interface of the VLNC2 SYSCTL circuit pack for administration of TDM operations for the VLNC50/52/55, VLNC35, and SYSCTL, or to the CLI interface of the VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 for administration of the functions of each circuit pack.
SYSCTL craft interfaces
Local craft interfaces available from the SYSCTL circuit pack are generally accessed on-site through a serial connection to the RS-232 port on the circuit pack faceplate. The serial port on the SYSCTL circuit pack can be used for an on-site CIT and TL1 administrative connection, and for software downloads.
Alcatel-Lucent 1850 TSS-5 also has a LAN port on the SYSCTL circuit pack faceplate. The LAN port, normally used for remote access, can also be used for on-site access. A network connection to the LAN port supports TL1 over OSI and IP network connections. Software download via FTAM or FTP is also supported.
VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 craft interfaces
The VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit packs operate independent of the SYSCTL circuit pack, and are configured using their own internal command line interface (CLI). Two RJ45 connectors on the VLIU interface unit provide RS-232 connections to the MAIN slots. One of RJ45 connector can be used to establish a serial connection to a VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit pack in the MAIN 2 slot, and the other can be used to establish a connection to a VLNC60/VLNC61/VLNC62/VLNC64 in the MAIN 1 slot.
The VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit packs also have a LAN port on their faceplates, that can be used to access the CLI via a TELNET or SSH connection from a properly configured PC, connected with a crossover cable. The LAN port has a default IP address that can be changed, using a CLI serial connection through the serial port on the VLIU interface unit associated with the MAIN slot in which the circuit pack is located. If an appropriate IP address is assigned to the LAN port, it can be connected and accessed through the office IP network.
Note:
Refer to Table 6-1, VLIU compatibility for more information about supported configurations.
Remote Operations System (OS) TL1/CLI/LAN interfaces (operations level 3)
The third operations level consists of the remote access to OS interfaces. Access for TL1 and related SONET/SDH network monitoring is provided via the CIT LAN and serial connection to the SYSCTL. Access for the Command Line Interface of Ethernet circuit packs that operate independent of the SYSCTL circuit pack is provided via IP network and serial connection to the circuit pack.
The following figure shows how the Alcatel-Lucent 1850 TSS-5 works with the various operations interfaces.
Figure 5-2: Alcatel-Lucent 1850 TSS-5 operations interfaces
For SONET/SDH operations using the SYSCTL, the OS can use more than one NE as a GNE to provide redundancy and distribute the TL1 message volume across multiple links to the OS. The TL1 GNE serves as a single interface to the OS for NEs in the same subnetwork. The TL1 GNE receives operations information from NEs through the DCC. It reports this information, and its own information, to the OS using TL1 messages. The OS can send TL1 commands through the GNE to any NE in the subnetwork. Alcatel-Lucent 1850 TSS-5, as well as other-vendor NEs that adhere to GR-253-CORE, can serve as the TL1 GNE for Alcatel-Lucent 1850 TSS-5.
CIT LAN (IAO LAN) and RS-232 CIT (Serial)
The LAN interface on the SYSCTL circuit pack can be used for a CIT network connection to the unit. OSI or IP based network connections are supported. OAM&P activities such as loopbacks and testing, protection switching, provisioning, PM, retrieving reports, and security on other Alcatel-Lucent 1850 TSS-5 NEs in a subnetwork are supported through the WaveStar® CIT.
A remote WaveStar® CIT connection through the serial port on the SYSCTL circuit pack is also possible if the port is equipped with a modem for remote dial-in access. However this port is usually used for on-site serial access to the unit.
CLI LAN and RS-232
The VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit packs are configured using their own internal command line interface (CLI) accessed via a serial or an IP network connection or from the web-based graphical user interface (GUI). A local CLI connection can be established through one of the RJ45 serial ports on the VLIU interface unit. A remote connection to this port is also possible if the port is equipped with a modem for remote dial-in access.
The VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit packs have a network connector on their faceplates. When the port is properly configured, the VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit pack can be connected to an administrative IP network through this connector, and can be accessed remotely by a TELNET or SSH connection.
