  4. 4. Teleste Proprietary. All rights reserved. Migrating from DOCSIS 3.0 to 3.1 “The Challenge” What is key to success • Network reliability & performance • Quality of Service all the way in to the home • Customer satisfaction Do we have this today?
  5. 5. Teleste Proprietary. All rights reserved. Migrating from DOCSIS 3.0 to 3.1 “The Challenge” Work in progress! • Bad contacts • Poor connections • Damaged cables • Intermodulation • Common Path Distortion (CPD) • Ingress/Egress! • Screening effectiveness of the in-home domain!
  6. 6. Teleste Proprietary. All rights reserved. Migrating from DOCSIS 3.0 to 3.1 “The Challenge” Ingress • 90% induced by subscribers • Ingress perceived as an upstream issue • Ingress perceived as a network issue • DOCSIS 3.1 will allow higher modulation schemes with current network C/N but what about to day (Can we take our foot of the gas)? New Kids On The Block • Down Stream ingress C/N interference • Down Stream egress interfering with wireless services
  7. 7. Teleste Proprietary. All rights reserved. Can ingress/egress get any worse? New services being deployed • Deployments in CATV Band (700 -1200MHz) • Higher powered handsets and base stations • CPE equipment sensitive to LTE interference • Regulatory obligation not to transmit CATV signals outside of closed network (Egress)
  8. 8. Teleste Proprietary. All rights reserved. The problem Ingress/Egress/LTE interconnect RFI shielding effectiveness • Open ports of wall sockets • Open ports of passive splitters and taps • Loose RF connectors • Open RF connectors • Poor or damaged RF cables
