Zero Touch Provisioning
1
Agenda
 Overview of Zero Touch Provisioning (ZTP)
 ZTP in PANS
 Issues with ZTP in BAN
 Possible ZTP solutions for BAN
 Deployment Example
What is Zero Touch Provisioning
(ZTP)
Theory
 Automated subscriber and service provisioning system (SSPS)
 Subscribers and services are created with the bare minimum
human intervention
Practice
 Largely automated SSPS with human intervention required
 Full automation is can be
 Uneconomical
 Insecure
ZTP in Dial-Up over Plain Old
Telephone Service (POTS)
 ZTP for Dial-Up access has existed for a number of years
 Pre-paid
 Subscription
 It is rather easy to implement as there is no requirement to
configure NEs

Issues with ZTP on DSL (PANS)
 Subscriber line patching and qualification between MDF
and DSLAM is largely a manual process
 DSLAM and ATM (if present) may need to be provisioned
for each subscriber
 Subscriber self installation not always successful
 Truck rolls are a necessity for installations where
• New copper runs are required
• POTS splitter installation
• CPE installation failure

Opportunities in BAN
 Ability to provide more than 1 service
 Opportunity to up sell additional services
 Broader revenue streams
 Examples:

128 / 256 / 512 / 1024 kbps Internet services
Multimedia on Demand
Application on Demand
VoIP, Video conferencing
Captive Portal
 Flexible and open service activation interface
Opportunities in BAN (2)
Multi Service offering
Over Broadband Access Networks
Lease Lines
Dial Up
Service Activation Interfaces
 1st Generation
 Single service
 Activated during subscription
 2nd Generation
 Multiple services but only 1 available at any one time (OR
model)
 Activated during log on
 3rd Generation
 Multiple services, any available at any time (AND / OR
model)
 Activated any time

Summary
 ZTP allow operators to reduce manpower cost in customer
acquisitions
 ZTP allow operators to easily roll out multiple services over a
single Broadband Access Network
 3rd Generation Subscriber Service Activation Interface allows
zero touch provisioning and activation
 Advantage for operator:
 More services - broader revenue base
 ZTP – faster service rollout and customer commissioning
 Advantage for subscribers:
 Choice of services and when they want it
