Network Management Systems (NMS) Features Quiz

Study Notes

MLLN NMS Overview

Network Management System (NMS) designed for MLLN (Multi-Layer Laser Network).
Tellabs Network Manager Release 13 is utilized to fulfill MLLN NMS requirements.
Supports regional partitioning and Virtual Private Network (VPN) capabilities.

Network Monitoring and Management Features

Performance monitoring includes uptime statistics and reasons for downtime.
Proactively generates circuit fault reports for timely detection and rectification.
On-demand bandwidth increases without modifying existing hardware.
Rapid circuit provisioning with low lead time for new service creation.
Circuit failure protection provided via automatic or manual recovery management.

Node Types and Capacities

Nodes function as digital multiplexers with various trunk and channel interfaces.
Cluster nodes serve as high-capacity cross-connect devices; expandable without interrupting traffic.
Basic nodes and midi nodes are flexible multiplexers; support customer access for tributary port capacity.
Mini nodes serve as low-capacity access multiplexers for smaller configurations.

VMUX Configurations

VMUX (Virtual Multiplexer) types include Type I, II, and III with specific configurations:
- VMUX Type I supports 32 N*64 kbps E1 Links.
- VMUX Type II supports 16 N*64 kbps E1 Links.
- VMUX Type III handles 8 N*64 kbps E1 Links.
Expansion possible via adding cards to the same chassis.

HDSL and NTU Specifications

HDSL driving distances for different bandwidths:
- 3.5 km at 2 Mbps
- 5 km at 1 Mbps
- 7 km for 64/128 kbps (utilizing 0.5 mm diameter copper cable).
Network Terminating Units (NTUs) provide various connection capacities (64/128 kbps, N x 64 kbps).
All NTUs support ITU-T Rec V.54 line loop testing with power-off signaling capabilities.

Accelerator and Micro Nodes

Accelerator Node A111 integrates PDH and SDH technologies; supports STM-1 interface.
Micro nodes function as small capacity cross-connections, particularly in mobile networks.

Cluster Node Specifications

Built on a master-slave architecture with a master sub rack and 1 to 8 slave sub racks.
Each slave sub rack can be single, double, or midi sized; total cross-connect port capacity reaches 512 Mbit/s.
Cluster node facilitates cross-connect at TS (64 kbit/s) levels and is capable of structural expansion.

Application of MLLN

Provides corporate high-speed internet access and various connectivity solutions, including:
- Broadband and LAN interconnections.
- Voice hotline connectivity.
- Point-to-point and point-to-multipoint connections.
Fully centralized management through the Network Management System.
