1.2 LA-110 Product Overview
LA-110 is an advanced ATM Integrated Access Device (IAD) that provides voice,
data and LAN services over ATM networks for small and medium-sized businesses.
The services supported by LA-110 include:
• High-quality leased lines for analog voice or data
• High-speed data (serial and Frame Relay)
• Ethernet with MAC bridge for LAN-to-LAN or Internet access.
This wide range of services provides maximum flexibility for service integration,
ease of use and scalability. Moreover, LA-110 uses cost-effective SHDSL lines for
connection to the ATM network, offering long range over widely available twisted
wire pairs.
1.3 5620 Network Management Architecture
The 5620 Network Management System consists of three management layers,
from bottom to top in the hierarchy:
1. Element management layer
2. Network management layer
3. Service management layer.
The Alcatel 5620 NMS open architecture facilitates the integration of multi-vendor
devices management. Employing Model Descriptors (MDs), it can manage SNMP
and TL1 third-party elements. The MD interprets SNMP messages between the
managed devices and the 5620 Descriptors Module (formerly 5520 SNMP
Element Manager). Using a descriptor, the service provider can manage
provisioning of new nodes or modify and support existing ones.
The Alcatel system allows the network administrator to maintain multiple MD.
Management capabilities are easily extended for new node types by simply adding
relevant MD to the ensemble. A dedicated descriptors ensemble for each node
type is required (see Figure 1-2).
