3 What is Remote?
4 Remote is a collection of specifications sanctioned by CableLabs that allows OCSIS to ride over an ernet Network CableLabs, MHAv2 Series CM-SP-R-: Remote System Specification CM-SP-R-EPI: ownstream External Interface Specification CM-SP-R-UEPI: Upstream External Interface Specification CM-SP-R-TI: Remote OCSIS Timing Interface Specification CM-SP-R-OSSI: Operation support Systems Interface Specification CM-SP-R-GCP: Generic Control Plan Specification CM-SP-R-OOB: Out of Band signals Specification **No new ernet requirements.
5 R Framing ernet Header 802.1Q VLAN (optional) MPLS Header (optional) IPv4/6 Header L2TPv3 Pseudowire Header Payload OCSIS Frames ernet CRC HUB R- Operation Systems Billing System OCSIS Core VIEO Core R- Framer Client to Client. Backhaul Aggregation Router R- OCSIS Analog Modem R omain ernet Physical Layer
6 Remote- defines Pseudowires (L2TPV3) that transmit: -OCSIS (data traffic) -Broadcast Video -and management within an IP packet and an ernet frame. - Transmitted over ernet physical layer - ernet/ip frames make OCSIS/Video invisible to the network - no impact to coaxial plant, packet cores, modems & OSS/BSS - OCSIS data makes up the bulk of the payload volume - Allows a multivendor interoperable environment.
7 A note on Service Cores OCSIS and Video cores organize and distribute a bandwidth availability per the policy given by Operation and Billing systems. (OSS/BSS) OCSIS data is unique per service group. Video can be unique per service group or the same for two or more service groups. When video is the same for all service groups we call it broadcast Fox, CBS, NBC, etc.

11 What is the capacity needed for the Remote ernet Backhaul?
12 Backhaul Capacity (Gpgs) Client to Client R- Backhaul Capacity Single direction capacity- download Router in Agg servicing: 16 s 4 or 8 nodes per OCSIS service group Compounded annual growth rate CAGR 40% OCSIS ata Static 1.25 Gpbs Broadcast video US 4 PR per SG LATAM / EU 4 RP per SG US 8 RP per SG LATAM / EU 8 RP per SG Broad Market View United States (US) SG start at 3 Gbps Lating America / Europe (Latam/EU) start at 1 Gbps Start in 2019 because most capacity has already been purchased until then Timeline (Yrs)

14 Backhaul Optics Adoption Timelines Backhaul Capacity (Gpgs) US 4 PR per SG LATAM / EU 4 RP per SG US 8 RP per SG LATAM / EU 8 RP per SG (1) 200 G 150 (1-2) 100 G (1-5) 10G ZR Timeline (Yrs) Adoption time frame is dependent on cost delta between G WM ZR to100g WM optics Early deployments with WM 10G ZR, quickly exhaust fiber capacity.
15 100G client (ernet) specification is needed today to enable R is full scale deployments G standard is necessary now. Routers must be installed day one with capability to grow to 100G backhaul. - note, 200G is also useful, but 100G is the high volume runner with expected robust cost reductions.
