Hardware Requirements
Operating System Requirements
The Telex PTToC Virtual Matrix can be installed on virtually any modern Windows based
operating system however Windows 10 Professional x64 or Windows Server 2019 x64
are highly recommended.
Memory Requirements
The memory requirement for the Telex PTToC Virtual Matrix are very minimal and system size does
not realistically need to be considered. It is recommended to use 8GB of memory
with any modern OS which will also provide sufficient resources for operation of the
Virtual Matrix.
Storage Requirements
The storage requirements for Telex PTToC Virtual Matrix in the standard configuration are not
substantial but some incremental storage space is required for Activity/Debug Logs.
In the standard configuration, a minimum of a 128GB SSD is recommended although
a 256GB SSD is preferred. An SSD is specified only for reliability.
Network Requirements
Bandwidth Requirements
The network bandwidth requirements must be carefully analyzed to ensure proper
bandwidth is available at any point where multiple clients will share the same physical
connection point. The most obvious connection point where this is critical is at the
server where bandwidth requirements will be the sum of the requirements of every
possible client. The least obvious connection point where this is also important occurs
when multiple remote clients in one physical location need to access the server in
another physical location as the bandwidth requirements for the connection between
these two points will be the sum of the requirements for all remote clients.
To determine the bandwidth requirements it is necessary first to determine the network bandwidth utilization per client connection, which is indicated below for the various audio sample rates that can be configured.
Telex PTToC:
| Audio Sample Rate | Data Rate (Kbps) |
|---|---|
| 48 KHz | 200 |
To determine server bandwidth requirements, first determine maximum potential bandwidth utilization by multiplying the number of clients (users and devices interfaced) by the Data Rate associated with appropriate Audio Sample Rate for the configured Audio Time Slice per packet. The product is the bandwidth required if every client were to receive audio simultaneously (maximum download bandwidth requirement) and also the bandwidth required if every client were to send audio simultaneously (maximum upload bandwidth requirement). In a typical system, the maximum download bandwidth requirement must be allocated for, as several system functions can require simultaneous audio transmission to all clients. The maximum upload bandwidth requirement however will realistically never be achieved as it is not feasible that all audio sources in a system would be active simultaneously since the result would be inaudible. As such the upload bandwidth to be allocated must be made based on the estimation of the number of simultaneous active audio sources noting that inactive audio sources will have no bandwidth requirements.
Firewall Requirements
Telex PTToC requires certain ports to be traversable through firewalls to allow the various components to connect. Factors such as the network location of the hardware and of the PTToC clients that will connect to the Virtual Matrix as well as where those connections originate will need to be considered. For the initial configuration, it is recommended to completely disable the Windows Firewall. The diagram and the chart below indicate which ports are required for all components.
The IP-224, the C-Soft Console and the Virtual Matrix Secondary Server will generally coexist on the same private network segment as the Virtual Matrix Primary as as such there may not be any firewalls between.
The PTToC clients are most likely to exist in the public network outside of the private network. In such case there will be a firewall to traverse. By default, the clients establish their initial connection to the server on the standard HTTP/HTTPS ports of 80/443. Note that the HTTP port is optional as it sole purpose is to redirect any HTTP request to an HTTPS request. In addition to the standard HTTPS port, a default WSS port of 444 is also required to complete the connection. As forwarding the standard HTTP/HTTPS ports may not be possible, it may be required to change the default HTTP/HTTPS ports in the System Administration → System Settings dialog. Note that the WSS port will always be 1 greater than the HTTPS port. If the HTTPS ports is changed, all clients must then append the new port number to the Virtual Matrix Host Name (eg 100.100.100.100:8443).
| Port or Port Range | Protocol | Description |
|---|---|---|
| 80 | TCP (HTTP) | System Administration and Telex PTToC App data (Unsecure) |
| 443 | TCP (HTTPS) | System Administration and Telex PTToC App data (Secure) |
| 444 | TCP (WSS) | Telex PTToC App Signaling data (Secure) |
| 1001 | TCP (IOIP) | Telex PTToC Virtual Matrix Failover data |
| 49152 to 65535 | UDP (WebRTC) | WebRTC Media audio |
| 1054 to 65535 | UDP (Multicast) | Connection to C-Soft Console |
| 1054 to 65535 | UDP (Multicast) | Connection to IP-224 |
The C-Soft Console and IP-224 use the UDP multicast address range 224.0.0.0 to 239.255.255.255.
Software Installation
Download Telex PTToC Virtual Matrix from our downloads page and unzip the installer.
Run the installer and follow the prompts. You will need to accept Telex License Agreement to install the software. During the installation process you will be asked if you want to install the Telex PTToC Virtual Matrix to run as a service or application. Servers should run Telex PTToC as a service.
Licensing
To license your Telex PTToC System you need to acquire a valid license file from Telex. To do so you must provide Telex with your unique ‘System Identification Code’ generated automatically when you install the Telex PTToC Virtual Matrix. The ‘System Identification Code’ is a unique value specific to the computer on which the Virtual Matrix was installed and is not transferable to any other computer. If the server you are running the Telex PTToC Virtual Matrix on has dual network cards make sure the primary NIC to be used is select as the Primary Server IP Address in the System Settings before sending the system identification code as it is dependent on the network card being used.
1) Log into the Telex PTToC System Administration and select License from the System tab at the top of the screen.
2) If you do not have a Telex PTToC license copy the code and send it to your Telex PTToC sales representative. If you already have a Telex PTToC license click 'Upload License' and select the license file.
