  6. Summary of key NMS differentiators • Single screen for Multi-service Provisioning • Manages Network nodes (iMAP) + CPE (iMG + iBG) • Multi-services - VoIP POTS, E1/T1 lease lines, Multicast IPTV, High Speed Internet Access • Multiple media - copper twisted pairs and fibre (P2P & P2MP) • GbE & 10GbE Protected Transport Rings • XML/SOAP northbound interface • Subscriber Web Portal – self provisioning

  7. Provisioning Services • “A ONE screen affair”

  8. The Requirement – Deliver Multiple Services to a Subscriber via a single network connection Single Network Connection Service Provider 1 Service A - data Service B - voice Service Provider 2 Service X - data Service Y - voice Service Z - video Customer - name Location – address Connected to – port, chassis Services – Data - Service Provider 1 Voice – Service Provider 2 Video – Service Provider 2 Connecting Services to Subscribers …. Services are provisioned for delivery via an Ethernet access network

  44. iMG Auto Configuration via AlliedView NMS DHCP Server (Option 82/60 support) 2. DHCP server provides to RG: - its IP address and also the - IP address of the tftp server (NMS) - “bootstrap” directory (per RG type)at tftp server 6. Use DHCP Listener to Discover RG Mgmt IP address. DHCP Server “Listener” 6 NMS iMAP’s DHCP Relay configured to send DHCP to both Server and Listener Via MAPMgmt VLAN 7 5 2 7.
