1 Switzerland - 1 Switzerland - 1 Courses CHP588 CHP589 SOPHO 2000 IPS Networking Concept

2 Switzerland - 2 Network Concept This chapter covers the following areas 2000 IPS System Networking Remote PIM CCIS Multi-Vendor Networking Public Switching Connection VoIP Mobile Solutions

3 Switzerland IPS System Networking CCIS CCIS Networked systems for multi-site organisations Up to 255 nodes: configuration for > extensions free extension numbering (8 digits) call routing optimisation (LCCR) high level of feature transparency enables centralised functionality: directory dialling operator management messaging voice mail Network Management Central Operator Analog, Digital, IP CCIS: Common Channel Inter-Office Signalling

4 Switzerland IPS System Networking Inter-Site Choice of inter-site network interfaces to match traffic with costs IP Frame Relay E&M analogue E1 2Mbps Voice transmission Call control Signalling Voice and Signalling ISDN CCIS networking on-demand call set-up

5 Switzerland IPS System Networking Inter-Sophos CCIS Networked systems between SOPHO platforms CCIS over IP SV IPS is3000

6 Switzerland IPS System Networking Multi-Sites 1/3 Multi Site IP Phones Acts as one system: Management PSTN / ISDN Centralized Call Processing Centralized System Data Single Point of Entry Management 2000 IPS WAN Dispatching Centre e.g. Headquarters Substations e.g. Branch Office

7 Switzerland IPS System Networking Multi-Sites 2/3 Multi Site IP DECT Acts as one system: Management PSTN / ISDN Centralized Call Processing Centralized System Data Single Point of Entry Management 2000 IPS WAN Dispatching Centre e.g. Headquarters Substations e.g. Branch Office

8 Switzerland IPS System Networking Multi-Sites 3/3 Multi Site - Remote PIM over IP Management PSTN / ISDN Conversations are rerouted PSTN / ISDN 2000 IPS WAN Stand-alone mode: Full functionality Local break-out 2000 IPS Dispatching Centre Substations

9 Switzerland - 9 Remote PIM 1/2 One main site and max. 30 remote sites can build up a large single PBX with multi-site distribution. Each remote can work as standalone PBX, in case the link to main site is broken.

10 Switzerland - 10 Remote PIM 2/2 Remote PIM main characteristics Can have their own TDM/IP extensions/trunks Transparent extension and network features throughout distributed system (it is one system.) IP phone Peer to Peer In case main site is not reachable, remote sites can work as independent IPPBX (survival mode) Limitations: no operator attendant console, no DSS, no ISDN terminal, no AP00, recommend to program the system from main site only.

11 Switzerland - 11 CCIS Common Channel Inter-office Signalling (CCIS) Advanced NEC proprietary signaling Transparent user and trunk features throughout the CCIS network Supported also by is3000 systems CCIS signaling through both TDM and IP trunks Network Management TDM or IP connection Centralized Operator

12 Switzerland - 12 Multi-Vendor Networking 1/3 Analogue E&M 2 or 4 wire configurable Support Types 1 and 5 Support continues and Wink signaling Support DTMF and pulse dialing Priority Call features (coming soon) Adjustable transmission level Adjustable timing 2000IPS 4ODTA 4 interfaces on board E&M interfaces Transmission Equipment Transmission Equipment E&M interfaces Other PBX E&M trunk Interfaces

13 Switzerland - 13 Multi-Vendor Networking 2/3 Digital 2Mbps QSIG (Q-reference Signaling) Digital 2Mbps E1 Channel Associated Signaling Remote Extension over E1 interface (to be implemented)

14 Switzerland - 14 Multi-Vendor Networking 3/3 H.323 or SIP to connect other VoIP telephone systems H.323 is set of standards defined by ITU-T SIP standard defined by IETF

15 Switzerland - 15 Public Switching Connection 1/3 PSTN Analogue Loop Start Signaling (FXS) Old and simple signalling, specification from customer is not required PBX works as an extension of PSTN exchange Charging meter, Power Fail Transfer, polarity reversal as start charging and/or release signal Main disadvantage: DID (Direct Inward Dialling) is normally not supported. An operator or specified extension needs to answer the incoming call from PSTN and transfer it to desired extension 2000IPS PN-8COTU 8 interfaces on board 2w analogue telephone lines Copper wire several km PSTN network

16 Switzerland - 16 Public Switching Connection 2/3 PSTN Digital ISDN Signaling ISDN standard defined by ETSI and ITU-T Most used worldwide PRA (30B+D) or BRA (2B+D) 2000IPS PN-DTA 30 channels 4w digital connections Copper wire several km Optical/HDSL connection PSTN network

17 Switzerland - 17 Public Switching Connection 3/3 SIP Signaling SIP standard defined by IETF Emerging as common standard for IP connection to Internet provider Provide ISDN like features 2000IPS IP-PAD IP connections SIP network

18 Switzerland - 18 VoIP 1/2 VoIP solutions VoIP applications IP phones and IP soft phone SIP phones (coming soon) CCIS IP trunk for interconnecting 2000IPS and is3000 systems SIP trunk for connection to internet provider H.323 trunk IP DECT VoWLAN Voice Peer to Peer for local connection and IP trunk connection Hybrid telephone system Integration into existing TDM network VoIP gateway: IP-PAD
