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.
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
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.
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.
The administrator can determine a schedule for the Mediatrix unit to periodically contact the ACS. These contacts will allow the Mediatrix unit to:
Monitoring is achieved by regularly sending notifications to the ACS, through the mean of "Inform" requests, which can be:
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.
The TR-069 protocol can be activated on units that are already deployed with a licence key (For more details on licences refer to How to activate a licence on a Mediatrix unit published on the Media5 documentation portal). However, it can be enabled/disabled for a specific configuration via the Management interface.
TR-069 methods supported by the Mediatrix unit include:
The Simple Network Management Protocol (SNMP) can be used to configure all the parameters available in the Mediatrix CPE, to perform firmware updates, to import a configuration and to monitor the Mediatrix CPE.
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.
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.
The Mediatrix CPE supports the following SNMP methods:
The following Management Servers are certified to be used with our Mediatrix units:
The Command Line Interface (CLI) provides an access to interactively configure all the Mediatrix unit parameters.
The CLI is accessed through either a secure SSH session (default) or an unsecure TELNET session. When using a secure SSH session, all communications between Client and server are encrypted before being sent over the network, thus packet sniffers are unable to extract user names, passwords, and other potentially sensitive data. This is the default and recommended way to access the Command Line Interface.
The command interpreter interface of the CLI allows the user to browse the unit parameters, write the command lines, and display the system's notification log.
The CLI supports several features and functionalities to facilitate the configuration of the parameters.
Restartmacro if restarting the service is required after changing a parameter through the CLI. The
Need Restartmessage will be displayed if a restart is required.
sysinfocommand. The information displayed includes:
Global>helpto display the list of all available keywords.
The Configuration Manager (Conf) service allows executing configuration scripts as well as performing the backup/restore of the CPE's configuration. Configuration scripts are files containing textual commands that are downloaded from a file server over the network to a Mediatrix CPE. Scripts can be downloaded using the FTP, TFTP, HTTP and HTTPS protocols. All available parameters used to configure the Mediatrix CPE are supported by the configuration scripts.
Written by the system administrator, scripts can be used to assign values to parameters or execute configuration commands such as:
The administrator can chose to trigger the execution of scripts in different ways:
It is possible to generate a configuration script from the configuration running on the Mediatrix CPE. This script can be used as a:
The automated importation of configuration scripts can be performed using a Customer Profile or using a DHCP server indicating the location of the file server with options 66 or 67. The automated importation to a CPE is what is referred to as zero-touch, as the CPE is automatically updated with the latest configuration scripts without manual intervention. Because the importation is initiated by the Mediatrix CPE, scripts have no problem passing through residential or enterprise NAT and Firewalls.
Mediatrix offers a very detailed level of configuration. This provides a powerful flexibility to adapt the configuration to almost any SIP implementation. SIP is a technology based on a list of RFC and 3GPP recommendations that SIP vendors address diferently. These differences led to interoperability issues that demanded frequent adaptations when deploying servers and endpoints from different vendors. The large list of configuration parameters available with Mediatrix CPEs make these adaptations possible.
The configuration database of Mediatrix devices is organised into services. Each service:
Parameters configure every aspect of the Mediatrix CPE behaviour including:
Access to parameters is granted according to administrator credentials, 3 access levels are supported. This is customizable in Customer Profiles. Manually accessing to configuration parameters is available though a web GUI, SNMP management servers and Command Line Interface.
Carriers and service providers usually define a configuration that will apply to a large number of units in compliance with the network architecture. It is the commands and the parameter values grouped in a text file that produce the Configuration Scripts.
To enforce security, configuration scripts can be encrypted and only Mediatrix units with the matching encryption key will be capable of decrypting and applying the configuration settings. Furthermore, configuration scripts can be downloaded and uploaded using HTTPS.
Configuration Script files are fetched by Mediatrix units from the network through any of the management interfaces available. Upon receiving the file, the Mediatrix unit executes each command line in sequence and assigns the values to the configuration parameters.
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.
For example, they can manage:
Security Certificates are files used to authenticate a Mediatrix CPE to other network elements and vice versa. In other words, they establish a secure connection, using TLS or HTTPS, between the Mediatrix CPE and the network elements. Security certificates contain attributes that identify a network element or an organisation. They also include a public or private encryption key.
Certificates are used to secure the following connections:
The Mediatrix CPE provides several troubleshooting features such as notification messages, diagnostic traces and SIP signalling logs.
The Syslog daemon is a general purpose utility for monitoring applications and network devices with the TCP/ IP protocol. With this software, you can monitor useful messages coming from the Mediatrix CPE.
Several features are available for monitoring.
