The Alcatel 5523 ADSL WorkStation is the key application for managing the xDSL Access Network.

The 5523 AWS is ALMAP basedThe ALcatel MAnagement Platform is fully object

oriented

The functionality the 5523 AWS offers is TMN based: Fault Management Configuration Management Accounting Management Performance Management Security Management

TMN Management Layers Scope

BML – Business Management Layer To manage the overall business: e.g. return on investment,

system decision support, market analysis

SML – Service Management Layer To manage services offered to customers: order handling,

service handling, billing, service development, planning

NML – Network Management Layer To manage network connectivity, routing,

protection in various topologies and across different regions

EML – Element Management Layer To manage Network Element’s configuration, alarms,

performances

DSLAM management

5523 AWS GUI This is the GUI explained in the rest of this presentation. Between AWS and DSLAM: IP-connectivity (SNMP, TFTP)

5523 TL1 gateway a separate application based on the non-graphical TL1 commands uses the same management path towards the DSLAM as the

AWS GUI It is possible to launch TL1 based scripts

5528 WAM (Web-based ASAM Manager) connecting using TCP/IP or RS232 serial cable

manage your DSLAM(s) from within your browser

Global architecture explained (1)

ANEL USM (AWS Network Element List) Global view on all NEs (ASAM/ISAM/ISAMV..).

Hierarchical or flat view. It is possible to create, modify and delete DSLAMs

PNM IM knows for each DSLAM, on which server the corresponding EML-

IM is running.

EML USM/IM (Element Management Layer) EML-IM communicates with the DSLAM One EML IM can handle several DSLAMs One EML-server can host several EML-IMs Similar IM processes: SGM, VOX (VEM), LANX+EML

40

Global architecture explained (2)

AS USM/IM (Alarm Subsystem) The AS IM receives alarms which can be shown in AS

USMs You can create alarm sublists CAL = Current Alarm List HAL = Historical Alarm List

PMV (Performance Monitoring Visualization) Set monitoring points on ports Performance storage PMV : table or graph

License keys

Different licenses exist: AWSCore 7324 RU ADSL2+ READSL2 IGMP

License keys are encrypted keys, based on : Host ID AWS release Duration Number of ports Number of operators
