Create A Detailed Network Diagram - Mitel MiVoice Business Voice Quality And Troubleshooting Manual

CREATE A DETAILED NETWORK DIAGRAM

A network diagram will help you to pinpoint potential sources of voice quality issues. For
example, electrical echo originates at the ends of 2-wire segments.
Create a diagram that shows both the analog and VoIP network components. When you create
the diagram, ensure that you show the following:
• Communication Platforms: Identify the number and type of communication platforms (for
example: MiVoice Business Virtual, MiVoice Business Multi-instance, MiVoice Business for
Industry Standard Servers, MXe, CX/CXi, AX controllers). If the system is resilient, identify
the primary and secondary controllers.
• Analog Service Units (ASUs) and controllers with main option boards and embedded analog
option boards
• Network Service Units
• Management platforms (for example, Mitel MiCollab or MiVoice Enterprise Manager)
• Phones: IP, Digital, Analog, Wireless
• ONS Lines
• PCs: Dual Port IP phones with connected PCs
• Analog Trunks: Label the trunks as (1) Digital; (2) 2-wire audio analog; (4) 4-wire audio
analog
• IP Trunks
• SIP Trunks
• VoIP Trunking Gateways: Identify the gateway type
• Layer 2 Switches
• Routers
• Firewalls
• IP Addresses
• Subnets
• VLANs
• Bandwidth on data links that connect network components
• Bandwidth Management Zones
• Quality of Service Levels
