1 Overview of CYTA s Network Management Marios Hadjiprocopiou NMC Manager/Systems Engineer January 2007 Fixed Network Services Network Management
2 Overview Cyprus Telecommunications Authority Offers probably the most advanced telecommunications network in the Eastern Mediterranean region Committed to meeting the area's ever expanding needs and business goals via a portfolio of competitively priced and flexible products January
3 CYTA NMS Overview The Network Management Departmental Structure NMC Network Supervision & Quality Management 24/7 Operation Management Systems Network Support Functional areas January
4 Network Management Overview (1) Network Management Architecture based on NMF Model Scope Business Management Service Management area the architecture covers Business Needs End-to-End Management Network Management Element Management NMS Network Elements Technology & Standards January
5 Network Management Overview (2) Network Management Structure Business systems Non real time systems NETRAC (FaM,CallXpert, PMM, NWV7,BCR,NCI2) TTI Network Traffic Management System XMATE / EM / Ericsson Per-Technology/Service/Vendor NE NE NE NE OSW3/NMC2 / EM / Alcatel NetManager/ EM / Siemens Per-Technology/Service/Vendor January
6 CYTA Fixed network infrastructure (1) Circuit-switched PSTN/ISDN network Based on Alcatel and Ericsson technology 22 TDM exchanges Offers class 5 services to residential and business customers Packet-switched ATM/Frame Relay network Based on Cisco technology 19 ΑΤΜ/Frame Relay nodes, geographically distributed all over Cyprus, interconnected via STM-1 (155Mbps) or STM-4 (622Mbps) trunks Offers ΑΤΜ and Frame Relay services to business customers with guaranteed bandwidth and Quality of Service January
7 CYTA fixed network infrastructure (2) IP/MPLS backbone network Based on Cisco technology 6 Cisco core and 40 Cisco edge routers Offers MPLS-based ΙP VPNs to business customers Infrastructure for transporting video services over ADSL (Video On Demand) Backbone network for interconnecting soft switching elements for transporting voice, data and video (Broadcast TV via ADSL) Soft Switch network Based on Siemens technology 7 Media Gateways, 2 Media Gateway Controllers Signaling overlay network and Number portability platform Used for class 4 replacement, internet traffic offloading and provision of next generation services January
8 CYTA fixed network infrastructure (3) The CYTA Switched Network Manufacturer Type Ericsson (PSTN) Alcatel (PSTN/ISDN) Siemens International Switching Centers Regional Exchanges 2 2 (AXE replacements) 4 (gradually phased out) 2 (Combi XGE with Regional and Intl operation) Local Exchanges 16 7 (Media Gateways Remote Subscriber Units 78 & Juniper Aggregation routers) other networks: ATM/FR, IN, IP/MPLS, GSM, ADSL, CYTANET January
9 Softswitch evolution Class 5 replacement Media Gateway + Softswitch + Feature Server Next generation services International Gateways TDM & SIP connectivity Class 4 replacement Media Gateway + Softswitch OPEX reduction Internet traffic offloading Initial step for long-term transition from circuit to packet switching January
10 NOC Basic Functions Continuous monitoring and control of international telephony traffic Monitoring of national fixed telephony traffic Monitoring of other CYTA networks and Systems (GSM, GPRS, ADSL, ATM, IN). In case of serious faults, the NMC is used as a reference point between CYTA and other networks/ operators DASR, RASR DOFL, ROFL, route congestions Current and Near Term NMS Services Interfaces Voice quality monitoring CDRs SS7 PSTN/ ISDN NGN VoIP NMS GSM IN ADSL Billing Warehouse January
11 Network Management Tools Overview Netrac Modules Implemented Fault Management (FaM) Performance Management Module (PMM) Network Command Interface (NCI2) Call Expert Best Cost Routing (BCR) Automatic Routing Recommendations and MML generation for 700 International Destinations Limited Network Configuration Network Wide View SS7 (NWV7) Switching Element Managers XMATE for Ericsson NMC2 /Webpack / OSWS3 for Alcatel NetManager for Siemens January
12 Integrated Network Management System (INMS) An international tender has been issued for the provision of an Integrated Network Management System (INMS) Tender Issued: 10 th November 2006 Tender Closing Date: 9 th March 2007 Operation expected to start: Q1/2008 A new Management Center is being re-organised to accommodate all of CYTA s requirements and facilitate management operations The INMS shall be an Inventory-Powered Network Management system consisting of an integrated suite of best-of breed software applications January
13 INMS System Architecture The INMS shall provide the entire range of management functionality (in accordance with TMN and e-tom) including: Inventory Management Fault Management Configuration Management Accounting Management Performance Management Security Management. The proposed system shall integrate management operations for CYTA s next generation networks and platforms (e.g. IP/MPLS, IP TV, ADSL, IMS, Soft Switch etc) under a single and unified platform In addition, the proposed system shall provide fault management functionality for CYTA s legacy networks (e.g. SDH, ATM, PSTN etc) January
