Unprovisioned unit can be shipped directly from the factory to the subscriber’s location without any
preprocessing by the Service Provider.
The PHONE ADAPTER contacts the Service Provider’s provisioning server via the IP network or
Internet when it is plugged into the subscriber’s home or business Local Area Network (LAN) –
assuming the provisioning server is reachable from the subscriber’s home network – to pull the
designated profile to be installed in that particular PHONE ADAPTER unit. Furthermore, th
ADAPTER unit will periodically contact the provisioning server to download an updated profile. The
protocol for downloading the configuration profile can be “clear text” TFTP or HTTP data or it can be
encrypted TFTP, HTTP or HTTPS data if security is required. Security will be discussed in more
details in a later section.

However, some basic information must be provided to the PHONE ADAPTER before it can be

1.1.3. Security Overview
Security may be applied at many levels in the context of the PHONE ADAPTER. The following are
examples of information that should be secured:
• The configuration profile pulled from the provisioning server – The downloading of the
profile should be secured since it contains authentication (password/user name ID /
number) information for accessing subscriber telephony services. It may also contain other
passwords and/or encryption keys used for a variety of management and service
operations.
• The administration password to the PHONE ADAPTER unit – The unit must disallow
access to administrative functions to unauthorized users. This access can be controlled
with an administrator password. The administrator password can be one of the parameters
in the PHONE ADAPTER configuration profile.
