<h1 class="title topictitle1" id="ariaid-title1">Provisioning a CPE for VoIP Deployments</h1>
<div class="body conbody"><p class="shortdesc">Over the last decade, the telecom industry initiated an intense migration from legacy
networks to Voice Over IP (VoIP). VoIP brings numerous benefits such as reducing communication
costs for end users, reducing operation and maintenance costs for carriers, and introducing a
large variety of new applications such as instant messaging, file sharing, video conference
and much more.</p>
<p class="p">With a large variety of functions, different Customer Premise Equipment (CPE) are used by
providers to deliver telecom services to residential and enterprise subscribers. CPEs
represent a significant component into the network to secure communications between parties
and ensure quality of service. CPEs also permit adapting the connection between legacy and
IP based systems, and fulfill advanced features in compliance with the evolving environment
of modern communications. For service providers, CPEs represent an important element of the
capital and operation expenditures. It becomes of major concern for CPE vendors selecting a
product design that will offer a competitive pricing structure, but also efficient
management tools that will facilitate enabling new services. The following sections provide
an overview of Mediatrix Product Line benefits and advantages for VoIP services
deployments</p>

<div class="body conbody"><p class="shortdesc">The Technical Report 069 (TR-069), also known as CWMP, is a Broadband Forum technical
specification. This protocol can be used to monitor and update the Mediatrix unit configurations
and firmware. In other words, when using TR-069, the Mediatrix unit can get in contact with an
Auto Configuration Server (ACS) to initiate a configuration script transfer/execution and a
firmware upgrade. </p>
<p class="p">The first time the Mediatrix unit is connected to the network, it will attempt to contact the
Auto Configuration Server (ACS), which is the entry point for the administrator. The Mediatrix
unit will obtain the URL of the ACS using either the DHCP server with option 43 or by retrieving
the information directly from the Customer's Profile. Therefore, upon start-up, the Mediatrix
unit will contact the ACS, which in return will send the required configuration files and
initiate, if necessary, a firmware update. This automated sequence is what is referred to as
zero-touch, as the Mediatrix unit is automatically configured by the ACS according to the
instructions given by the administrator without manual intervention on the unit.</p>
<div class="p">The administrator can determine a schedule for the Mediatrix unit to periodically contact the
ACS. These contacts will allow the Mediatrix unit to:<ul class="ul" id="concept_sfd_ljg_1r__ul_efh_f5m_1r">
<li class="li">verify if new configurations are available,</li>
<li class="li">verify if a new firmware update is available and</li>
<li class="li">send notifications for monitoring purposes.</li>
</ul></div>
<div class="p">Monitoring is achieved by regularly sending notifications to the ACS, through the mean of
"Inform" requests, which can be: <ul class="ul" id="concept_sfd_ljg_1r__ul_x24_k5m_1r">
<li class="li">Passive: the information is sent according to the schedule.</li>
<li class="li">Active: the information is sent immediately when a parameter status changes, regardless of
the periodic schedule.</li>
</ul>Because the Periodic Informs are initiated by the Mediatrix unit, they have no problem
passing through residential or enterprise NAT and firewalls. </div>
<p class="p">Furthermore, the administrator can initiate a connection to the Mediatrix unit to perform
immediate maintenance or monitoring. This will only be possible if the NAT firewall has been
configured to allow communications initiated by the ACS.</p>
<p class="p">The TR-069 protocol can be activated on units that are already deployed with a licence key (For
more details on licences refer to the<a class="xref" href="https://documentation.media5corp.com/display/DGWLATEST/How+to+Activate+a+Licence+on+a+Mediatrix+Device" target="_blank">Technical Bulletin - How to activate a licence on a Mediatrix

be enabled/disabled for a specific configuration via the Management interface.</p>

parameters available in the Mediatrix CPE, to perform firmware updates, to import a configuration
and to monitor the Mediatrix CPE.</p>
<p class="p">To configure the Mediatrix CPE parameters with the SNMP, a secure SNMPv3 or a non-secure SNMPv1
connexion can be used. The CPE does not grant an SNMPv3 access without authentication and
privacy. Because the connexion is initiated by the Management Server, the communication is
usually unable to go through the NAT Firewall. </p>
<p class="p">Unit monitoring is possible with SNMP because it provides access to all the status parameters
of the CPE. Furthermore, the CPE can send notifications, called traps, to the Management Server,
that will allow the administrator to monitor specific events. Because it is the CPE that sends
the notifications, the communication is usually able to go through the NAT Firewall however the
SNMP protocol, based on UDP, does not insure reliable delivery of notifications.</p>

<div class="body conbody"><p class="shortdesc">As defined in the Oxford Dictionary, authentication is the process or action of
verifying the identity of a user or process.</p>
<p class="p">In an Internet telephony network environment, authentication will allow the Mediatrix unit to
make sure the peer it is communicating with is the proper network or endpoint (unit or end-user
device). This provides a level of security for communications as no communication will be allowed
if the authentication is not confirmed. </p>

<div class="body conbody">
<p class="p">You can globally set the transport type for SIP all the endpoints of the Mediatrix unit to
either UDP (User Datagram Protocol), TCP (Transmission Control Protocol), or TLS (Transport
Layer Security). </p>
<p class="p">Please note that RFC 3261 states the implementations must be able to handle messages up to
the maximum datagram packet size. For UDP, this size is 65,535 bytes, including IP and UDP
headers. However, the maximum datagram packet size the Mediatrix unit supports for a SIP
request or response is 5120 bytes excluding the IP and UDP headers. This should be enough, as
a packet is rarely bigger than 2500 bytes.</p>

<div class="body conbody"><p class="shortdesc">Mediatrix CPEs offering session border controller capabilities address a large variety
of applications such as network demarcation, SIP firewall, SIP normalization and survivability.
To facilitate the implementation of these applications, Mediatrix session border controller
provisioning is based on a catalog of configuration templates named Rulesets. Rulesets define
one or several rules used to filter, manipulate or route inbound or outbound
requests.</p>
<div class="p">For example, they can manage: <ul class="ul" id="concept_twt_xr3_br__ul_dmr_qlb_br">
<li class="li">NAT Traversal</li>

<li class="li">SIP normalization</li>
</ul>By selecting these Rulesets, administrators will manage service activations following a
few steps procedure and saving valuable operation time. A Ruleset editor available with
Mediatrix session border controllers enables administrators to create new Ruleset or modify
existing ones to adjust settings to different deployment scenarios.</div>
