2 Channel Associated Signaling (CAS)

When using CAS signaling, each traffic channel has a dedicated signaling channel. In other words, the signaling for a particular traffic circuit is permanently associated with that circuit.

E&M (earth & magneto, or ear & mouth) is a type of CAS signalling that defines line signaling and register signaling. It is also called Signalling System R1 and is mainly used in North America. E&M was originally developed to allow PABXs in different geographic locations to communicate over an analog private circuit. Some digital interfaces such as CAS also use versions of E&M signaling.

The terms forwards and backwards are heavily used in descriptions of E&M.

  • Forwards is the direction from the calling party to the called party.
  • Backwards is the direction from the called party to the calling party.

2.1 Setting the Mediatrix Unit to Use the EandM Signaling Protocol

Steps
  1. Go to System /Hardware .
  2. In the PRI Ports Configuration table, located on the same line as the port you wish to dedicate to E&M signaling, from the Signaling selection list, choose E&M .

    Note

    When changing from E&M to ISDN/R2 or ISDN/R2 to E&M, you must change your routes accordingly. For instance, if you are in ISDN with a route isdn-Slot2/E1T1, then change to E&M, you must change the route to e&m-Slot2/E1T1.

  3. From the Line Type selection list, choose T1 .
  4. Click Apply .
  5. Restart the unit.

3 EandM Auto-Configuration

The E&M Auto-configuration feature allows the detection and the configuration of all, or a specific, E&M interfaces so that the E&M link goes up and becomes usable with a minimal user interaction.

When launching an auto-configuration process, it stops automatically when all selected interfaces have been tested. For each interface, the auto-configuration process is considered a success when the link becomes up or a failure when all combinations have been tried without having a link up.

During E&M Auto-Configuration, the following parameters are updated:

  • PortPinout : TE / NT
  • ClockMode : MASTER / SLAVE
  • LineCoding : B8ZS / AMI
  • LineFraming : SF / ESF

3.1 Auto-Configuring EandM

Context
Launching auto-configuration may terminate abruptly all ongoing E&M calls.
Steps
  1. Go to E&M /Status .
  2. In the Automatic Configuration table, from the selection list, choose the interface to auto-configure.

    Note

    Please note that some parameters cannot be auto-configured. For instance, the clock mode is configured according to the endpoint type, master for NT and slave for TE.

  3. Click Start Sensing .
Result
Auto-configuration on all E&M interfaces may take some time to complete. Some of the current E&M settings might be replaced by new values.

4 EandM Preset Configurations

It is possible to save a set of configuration as presets for future E&M connections.

Using preset files is especially useful for units that do not use the default values provided by Media5. These preset configuration files are located in the file system's persistent memory listed in the DGW Web interface, under Management /File and they differ depending on the Mediatrix unit you are using.

Note

Only script files can be used as R2 Preset configuration.

It is also possible to export the current E&M configuration in a Preset Configuration file.

Note

User-defined presets are not kept in the event of a factory reset.

Installed configuration scripts/images are listed in the DGW Web interface, under Management /File

7 Documentation

Mediatrix units are supplied with an exhaustive set of documentation.

Mediatrix user documentation is available on the Documentation Portal .

Several types of documents were created to clearly present the information you are looking for. Our documentation includes:

  • Release notes : Generated at each GA release, this document includes the known and solved issues of the software. It also outlines the changes and the new features the release includes.
  • Configuration notes : These documents are created to facilitate the configuration of a specific use case. They address a configuration aspect we consider that most users will need to perform. However, in some cases, a configuration note is created after receiving a question from a customer. They provide standard step-by-step procedures detailing the values of the parameters to use. They provide a means of validation and present some conceptual information. The configuration notes are specifically created to guide the user through an aspect of the configuration.
  • Technical bulletins : These documents are created to facilitate the configuration of a specific technical action, such as performing a firmware upgrade.
  • Hardware installation guide : They provide the detailed procedure on how to safely and adequately install the unit. It provides information on card installation, cable connections, and how to access for the first time the Management interface.
  • User guide : The user guide explains how to customise to your needs the configuration of the unit. Although this document is task oriented, it provides conceptual information to help the user understand the purpose and impact of each task. The User Guide will provide information such as where and how TR-069 can be configured in the Management Interface, how to set firewalls, or how to use the CLI to configure parameters that are not available in the Management Interface.
  • Reference guide : This exhaustive document has been created for advanced users. It includes a description of all the parameters used by all the services of the Mediatrix units. You will find, for example, scripts to configure a specific parameter, notification messages sent by a service, or an action description used to create Rulesets. This document includes reference information such as a dictionary, and it does not include any step-by-step procedures.
