NOC Case: How it all started

• Elisa and Teleste have a long term relationship in products

• In Network Design, the cooperation started in 2009

• In 2011 Cable Network – documentation & document hosting services started, and the cooperation was expanded to installations - the first project Turnkey Design & Installation for the HFC Network in Riihimäki

• Discussions for NOC cooperation were initiated in late 2012 and the agreement was signed in October 2013


Elisa’s Key Objectives for NOC cooperation

• Improving the quality of service experienced by the end-users & reducing the repair costs caused by truck rolls

• Sorting out faults, to the extent possible, from the control room

• Anticipating capacity constraints before they become noticeable to the customers

• Reducing costs of repairs carried out in the field, speeding up such repairs and improving the final quality of service


Scope of the cooperation

• Teleste's Network Operations Center, NOC, monitors Elisa's entire CATV/cablemodem network

• All glitches are analysed by NOC before any remedial operations in the field are launched. If possible, issues are corrected through remote maintenance

• Teleste's Element Management System (EMS) allows locating quickly any network faults and guiding the field technician directly to the relevant spot

• Disruptions can be minimised by preventing the fault from spreading in the network and limiting its scope

• Teleste takes care of the Capacity Management and monitoring of the network components


Services provided to Elisa

• Second level processing of CATV and cable modem fault tickets including fault-by-fault analysis and examination of the possibility to repair the fault remotely

• Monitoring of several production systems, such as CMTS and EMS

• Sending the defects requiring repair in the field over to the contractor's work queue

• Technical support and guidance for the fault repair contractor working in the field

• Monitoring and further development of network quality
