Distributed
Access Architecture
Services Suite
As the newest step in the continuing evolution towards an all-digital
headend, Distributed Access Architecture (DAA) extends the digital
portion of the headend/hub domain out to the fiber optic node and
places the digital/RF interface at the optical/coax boundary. This
strategic move offers many benefits, including increased bandwidth
capacity, improved fiber efficiencies (wavelengths and distance),
simplified plant operations with digital optics, decreased loads on
facility space and power systems, and directional alignment with
FTTx systems of the future.
Implementing DAA involves installing Remote PHY Devices (RPD’s)
in CommScope form-fitting nodes, supported by a Gen 2 E6000
chassis acting as an electronic Core (eCore.) Managing this
deployment across many headends and dozens or hundreds of
nodes is a time-consuming, potentially service-affecting activity
that must be approached with careful planning and execution.

changes required in their network to achieve a flexible, sustainable
network. CommScope’s skilled Project Managers, Deployment
Engineers and Technicians can manage and execute the transition
to DAA, allowing cable operator personnel to stay focused on
business as usual.
BENEFITS
· Leverage CommScope expertise for seamless upgrades
· Assurance of highest quality
· Timely management of resources and materials
· Focus staff on business as usual
· Manage execution across multiple sites to mitigate
PROFESSIONAL SERVICES
2 Distributed Access Architecture Professional Services
Four Categories of CommScope DAA Services Suite
Core/Edge Services Description
Site Audit and Documentation Review and updating of existing site-specific physical data required for the design and
integration of the CommScope E6000TM eCore integration.
Market Templates / Golden
Configuration / Operator Guideline
Create golden configuration to be applied to the eCore based on existing CMTS and other
operator supplied data. Contains information such as SNMP, TOD, NTP and provisioning
servers, user accounts, access control lists, and service classifiers.
Site Survey Review existing infrastructure to understand changes that need to be made to support DAA.
Engineering Design Plans Create detailed design and wiring plan to document how to install the new products into the
operator head end.
Site Specific eCore Configuration Create site specific configurations on a per eCore basis utilizing information from the node
combining plan, other operator supplied data and/or existing CMTS configuration data.
eCore Installation/ Upgrade Service The eCore Installation/Upgrade Services cover the physical actions of racking and stacking a
new chassis or performing a HW/SW upgrade to an existing chassis.
eCore Commissioning + Advanced SG
testing
Brings the powered up eCore to a minimal state of operational readiness, and ready for a site
specific configuration to be applied.
Maintenance Window Migration
Services
Assist with the integration of the new eCore and DAAS network with optional onsite/remote
eCore Engineer.
Installation, Configuration, Wiring,
Powering plans, Upgrades and
Deployment
Services available for third party and CommScope products including: R-Phy, VUE, vManager /
RPD Manager, Video Topology Manager, vCore, eCore, vCMTS, E6000 CCAP, E6000 Gen2
OSS/BSS Integration Ensure that the Orchestration systems (vManager, RPD Manager, Video Topology Manager)
integrate with back office systems.
RPD/vCore Integration Integrate RPD and vCore to ensure provisioning and all functions and features are enabled.
RF Recombining Services cover the physical actions of wiring to support the new RF Combining network for
migration to the new DAA architecture.
Distributed Access Architectures impact the Core and Edge Network by changing the functionality of the Core and moving some functions
to the Edge, closer to the Aggregation Network where the connection between the edge and outside plant occurs, and the Access Network
where services are delivered to the customer. CommScope has arranged its DAA Services Suite to align with these three network segments.
In addition, CommScope offers services that cut across the entire network project.
