Welcome to
the second of our blogs on subscriber activation. This month we’re looking at
the complex subject of CPE configuration and management.
If we step
back in time around five years ago the subject of customer premise equipment
(CPE) configuration and management was important to digital service providers
but arguably far less vital than it is today. DSPs have always struggled with
the issues around configuration and management of diverse CPE. However, the
development of the broadband forum’s standards (TR 69, 64, 111 and 176) for
ADSL CPE management and the increasing popularity of VoIP and IPTV have necessitated
that more sophisticated systems for CPE management be developed.
For today’s
ADSL broadband customer, activation means more than just setting up their PC.
It means activating their gateway with services, security and quality of
service (QoS) parameters, possibly configuring IPTV or VoIP equipment, and
potentially even activating other devices on their network. To enable this, an
auto-configuration server (ACS) is required and we shall look at some of the
challenges it overcomes below. But first,
let me share with you a story that will set the stage for why an ACS is so
important.
A large UK
company had a vulnerability revealed in its home gateway in 2007 that allowed
for “eavesdropping, caller spoofing and other nasty attacks”. Fortunately the
company in question had an ACS and so was able to rapidly update their deployed
gateways, but what would have happened had they not had this facility? How
would they have updated the 100s of thousands of gateways they had deployed?
Recall? Disk based upgrade? Outbound calling to customers? What about the
impact on brand equity and customer satisfaction? The impact to them as an
organization would have been significant, in the 10s of millions of pounds.
This is an extreme case but organizations suffer similar medium and low impact
events on a regular basis all of which have a cost associated with them.
Implementation of an ACS can be seen as an insurance policy that pays dividend
when something like this occurs and can be quickly resolved.
Having the soft touch
If you’re managing activation of services in a customer’s home then
there are probably four things that are of utmost importance to you:
Customer
experience – First
and foremost you want your new subscriber to have a great installation
experience. This will determine their attitude to you and ultimately even
contribute to whether or not you retain them as a customer. It’s far easier to
create an initial good customer experience than to attempt to repair a bad
relationship created by a poor customer experience. Installation
quality – The
quality of any installation can have a long term impact on the quality of
service a subscriber receives. Detecting problems at point of install that can
then be rapidly solved by an engineer prior to him leaving the customer’s
property is likely to have a very beneficial impact on the customer’s
satisfaction with your service. Time! – If you’re conducting engineer
installs, time *is* money. A lot of DSPs use third party engineers to conduct
installations. Simply rolling a truck to a customer’s home is likely to set you
back $ 50 - $ 100 before you start to account for any extra time the engineer
has to spend at the customer’s location. On-going
maintenance –
Whatever CPE is installed at the customer’s home you want to be able to
continue to maintain it once you’ve left the customer’s location. Part of this
is simply being able to update modems with new firmware but there is also the
requirement to be able to enact service policies such as bandwidth usage, user
quarantine, abuse management and security management.
Motivated by Installation
I have found that there are three primary motivators of customer
satisfaction with an installation: simplicity, reliability and speed.
SIMPLICITY: Zero-touch configuration allows the customer
to simply connect the device to the network and an ACS automatically triggers
power cycling of the device, enables services and triggers any required
provisioning. The customer is oblivious to any of this, they just knows that
their device works immediately (or very nearly so) without them needing to go
through a complex set up procedure.
RELIABILITY: Zero-touch configuration delivers
reproducibility and removes the potential for human error ensuring that every
installation follows a distinct and known path. This contributes to a high
quality of installation. It also has the ability to look at modem parameters
such as line attenuation (the degradation of signal to a modem generally due to
distance and physical line characteristics). This can give an engineer or call
center representative a clear indication of whether the quality of an
installation is good and allow them to take immediate action to improve the
line quality if required.
SPEED: Zero-touch provisioning also potentially
means not having to role a truck, or at the very least, significantly cutting
down on the amount of time an engineer spends at a customer’s home. To
understand the impact of this, imagine for a moment that you have a DSP that is
doing 30,000 IPTV installs a month at a truck roll cost of $100 per truck roll.
Remove the need for this truck roll and you’re instantly saving $3 M a month or
$36 M a year. Even halving the time an engineer has to spend at a customer home
would have a significant impact on costs.
Closing Thoughts
Although not strictly part of the activation process the foundation
for on-going maintenance is laid down during activation. The use of an ACS to
activate gateways or other LAN devices means that they can be connected to
thereafter for maintenance activities. In my mind this is the single most
important activation benefit that an ACS provides, not only does it allow for
the auto provision of new, free and paid services but it also allows for the
automatic update of devices as seen in my earlier story.
So to summarize, a good DSP activation process has a number of
requirements that necessitate the implementation of automated systems. A
combination of disk based install and an auto-configuration server provides a
flexible solution that meets the majority of these needs.
