  2. Branch A Head office 400~450 Centralized Attendant Branch B • ISDN • IP network • ATM, FR etc 100~399 500~599 Centralized Voice mail Branch C 600~650 1. What is Voice Networking? Voice Networking Provides a way of communication to inter-work between networked system over various networks. • Headquarter to Branch offices • Chains • Office to Cargo • Building to Building 1/20

  3. 1. What is Voice Networking? Background • Offices are located everywhere.  Should provide more efficiency for office worker. • Cost is growing and growing between Main and Branch offices. Benefit • Provide single network as one system • Cost effective with sharing the resources among multi-sites 2/20

  4. 1. What is Voice Networking? Protocols • DPNSS(Digital Private Network Signaling System) • QSIG of ETSI standards over ISDN • H.450 of ITU standards over VoIP • Proprietary protocols for enhanced feature by each vendor Remark1) RSG : Remote Service Gateway 3/20

  5. IP Network 2. LG Solution Diagram RSG LDK-300E(CS-1000) DSL or Cable Modem Router Home Office BLF Manager Headquarter Office LDK-24 Small Branch Office LDK-100 Router LIK-300 Branch Office Router Local Main Office 4/20
