The 1643 AM/1643 AMS are configured for remote and local operations management via the Alcatel-Lucent Optical Management Solution and SNMP management solution. Remote management can be realized via the STM-1 or STM-4 DCC and the Alcatel-Lucent OMS or ITM-CIT software.
1643 AM/1643 AMS is configured for remote and local operations management via the Alcatel-Lucent Optical Management Solution. Remote management can be realized via the STM-1 DCC and the Alcatel-Lucent OMS or locally via ITM-CIT.
Local connection is available via an RJ45 socket on the main board to connect a PC loaded with the ITM-CIT software.
Management access features include:
Simultaneous access by the element management system and local workstations
Remote access to other 1643 AM/1643 AMS in the same network by ITM-CIT
NE level security via three password controlled authorization levels: ADMIN, CONFIGURE and VIEW.
Transmission and equipment fault supervision is monitored remotely via the Alcatel-Lucent OMS and locally via LEDs on the unit and via the ITM-CIT. The local ITM-CIT may also be used to remotely access other 1643 AM/1643 AMS nodes in the same network.
Alarm and port termination monitoring features include:
Physical port provisioning of STM-1 or STM-4 aggregate, STM-1 tributary, E1, E3, DS1, DS3, SHDSL, X.21 and Ethernet ports in three different modes: automatic (AUTO), monitored (MON), or non-monitored (NMON)
VCx (x=11,12,3,4) and P12 (egress) path termination point provisioning in either the MON or NMON mode
Alarm severity levels of PROMPT, DEFERRED and INFORMATION provisionable for each alarm type by provisioning the alarm severity assignment profile (ASAP)
The user can assign an alarm message and severity to each MDI (miscellaneous discrete input) by provisioning the alarm severity assignment profile (ASAP).
Failure reporting features:
Failure reports are generated for equipment, configuration and software faults with sufficient information to identify the next step in the fault correction process
Alarm forwarding to the remote EMS (Element Management System) is supported via Alcatel-Lucent OMS (LAN-10BaseT) and to the local workstation via the F-interface (ITM-CIT)
The NE can store the 500 most recent alarm events and can be accessed by either the local or remote monitoring stations
Transmission failures are reported as defined in G.783 and ETS 300417
Centralized supervision alarm system. The ITM-CIT informs of each new alarm change for each accessible NE.
Software maintenance includes the following:
Local and remote software download via Alcatel-Lucent OMS or ITM-CIT, non-service affecting. Minor LAN traffic interruption may occur in case of switch of the software backup store in order to upgrade/downgrade the system.
Faster MIB download duration. The ARC timer is set to five minutes. If a local CIT or OMS connection is established within five minutes, the ARC process will continue. If the local CIT or OMS confirms the MIB download within five minutes, the 1643 AM/1643 AMS will restart. However, if the MIB download is not confirmed within five minutes, the 1643 AM/1643 AMS opens the DCC according to the parameters in the safeplace.
The 1643 AM/1643 AMS supports MIB upload and download functions to and from a PC via the local Q-LAN interface. The MIB image can be saved as a binary file. This feature is supported by the 1643 AM/1643 AMS and the ITM-CIT.
The MIB image that is uploaded from the 1643 AM/1643 AMS can be downloaded via the Q-LAN interface to the other NEs with hardware variations. For more information about the hardware variations, refer Software maintenance.
The 1643 AM/1643 AMS NEQ value is 0.25 and is compatible with the requirements of network management system.
In-service database reprovisioning available via the local workstation running ITM-CIT software.
The 1643 AM/1643 AMS supports the ITM-CIT and EMS to display a dynamic software download progress indicator per module. This module also indicates the software download percentage for the SHDSL module.
The “Fast download” tool permits to load the current software of the equipment via a PC connected to the Q-LAN interface of the equipment.
Important! Please note that the SHDSL feature is realized differently in Release 6.1 and later versions than in the previous releases. Thus it cannot be upgraded to Release 6.1 and later versions.

For circuit testing during maintenance operations, the system provides:
Loopbacks on incoming E1 , DS1, E3, DS3 and X.21 signals (loopbacks on E1/DS1/X.21 are exclusive)
Loopbacks on outgoing E1, DS1, E3, DS3, SHDSL and X.21 signals
NT1 (Network Termination) loop-back on a 2 Mbit/s line dedicated to ISDN.
Provisioning and retrieval of performance monitoring parameters are derived from the overhead bytes (SOH, POH of each VC) and are in accordance with ITU-T Recommendations G.874 and G.826. This is accomplished via Alcatel-Lucent OMS and ITM-CIT. Performance threshold counts are user settable. Each managed NE has a current data register for 15 minutes or 24 hours.
The following parameters are monitored:
Ethernet (LAN and WAN) performance monitoring information can be derived from bytes sent, bytes received and packets dropped. This information is available in 15 minutes or 24 hours registers.
ISDN Performance monitoring information can be derived for 2 Mbit/s signal from pN_EBC (Near-end Errored Block Count).
This information is available from:
Egress (Egress refers to the SDH to PDH transmission direction)
Ingress (Ingress refers to the PDH to SDH transmission direction).
For transparent E1 interfaces, it is possible to do near-end performance monitoring on each 2 Mbit/s signal in both directions (PDH to SDH and SDH to PDH) at the 2 Mbit/s system interface. Near-end information is obtained from CRC-4 violations and defects.
The 1643 AM/1643 AMS support the following diagnostic and recovery features:
The equipment continuously runs self-diagnostic tests to monitor the health of the transmission system
Anomalies are reported via system indicators (FAIL LED) or Alarms on the Element Management System and/or WaveStar® CIT
The equipment will auto-recover from a database failure by requesting the backup database be downloaded from the Alcatel-Lucent OMS.
The 1643 AM/1643 AMS support two LEDs which provide the following maintenance information:
The 1643 AM/1643 AMS provide four miscellaneous discrete inputs (MDIs) which can be used to read external devices assigned by the customer. Examples are monitoring temperature, humidity, open doors, etc.
The equipment provides four miscellaneous discrete outputs (MDOs) which can be used to drive external devices assigned by the customer. Examples are signaling devices, temperature conditioning, etc.
When not assigned by the customer, the 1643 AM/1643 AMS behave such that MDO 1 has been assigned to indicate a power failure (normally open contacts will close), MDO 1, MDO 2, MDO 3, MDO 4 are respectively assigned to power failure, Prompt, Deferred, Information alarms.
The 1643 AM/1643 AMS systems support one bidirectional HDLC-transparent DCCR connection between the two STM-1 line ports. Note that, selectable per port, either the MS channel or the RS channel can be used at the same time. This feature facilitates the interworking with third party equipment.
The user can select the LAPD protocol (ITU-T Q.921) for OSI layer 2 to be based on AITS (Acknowledged Information Transfer Service) or UITS (Unacknowledged Information Transfer Service). In the AITS mode the receive side sends an acknowledgement back to the transmit side, if a data packet has been received. If this acknowledgement does not arrive, the transmitter sends the packet again. In the UITS mode no acknowledgements are sent.
