PHYSICAL CONNECTIONS
The C510ip audio codec has two separate Ethernet connections. The first is a dedicated Web management interface and is labelled “MGR LAN” at the rear of the codec. The IP Audio
streaming Ethernet connection is also located at the rear of the codec and is labeled [ISDN ¾ – IP]. These two Ethernet connections are fully independent in terms of hardware and firmware and are implemented using different MAC addresses and software stacks on separate processors.
BROWSER: MANAGEMENT PORT DHCP
Connect the manager port Ethernet cable to your intranet and power on the unit. Then proceed to the menu,
Systembase C510ip -> System Options -> Ethernet Options ->Ethernet DHCP
Set DHCP to “ON” and proceed to the menu,
Systembase C510ip -> System Options -> Ethernet Options ->Ethernet IP
Once an IP address has been allocated by the DHCP server the address will be displayed here in the format xxx.xxx.xxx.xxx(dhcp).
BROWSER: CONNECT USING A WEB BROWSER
Now that we have an IP address allocated to the codec's management port you can connect using either IE8 upwards, Firefox, Chrome, Android or MAC OS based web browsers. This is achieved by entering the codec’s IP address into the address bar of the chosen browser package and pressing enter.
When connected the browser will present a login dialogue box as shown adjacent. To logon the default user name is “admin” and the default password is “admin”.
IP LINK: CONFIGURE IP AUDIO DHCP
Once connected you can proceed to the TAB labelled “IP CONFIG”
To enable DHCP address allocation for the IP Audio port, locate the option menu called “DHCP” and select “ON”. Now the screen will update and display the DHCP allocated address for the IP audio module will be displayed.
IP LINK: MAKE AUDIO CONNECTION
Configuring an IP connection is done using the “Remote Connections” tab of the configuration screen. The C510ip and C510ip-s codecs can handle multiple simultaneous connections at the same hence there are six remote IP address entries available. For a simple point to point IP connections we shall use the first entry.
To configure a remote connection you will require the IP address, domain name or SIP address for the remote codec. Once you have this, simply enter the address in the “Remote address” field of the 1st connection. Then select the required audio mode, format, sample rate and operating mode.
1/ If you wish to use the Systembase IP protocol then enter either the IP address or the Domain name of the destination codec and select audio modes APTX, G722 and PCM only.
The FEC drop down allows you to enable “Forward Error Control” on the connection. If “4” is selected from the dropdown menu then the receiving codec will be able to handle 1 in every 4 packets being lost on the network.
NOTE: FEC will only operate if you have enough packets in the receive queue. A FEC of 4 would require a minimum of 4 packets in the receive buffer at all times.
2/ For SIP protocol enter on one of the following: SIP address in the format e.g.
“sip:[email protected] ” if using a SIP server OR “sip:192.168.1.100” / “sip:c500xr.co.uk” if using point ot point SIP. In SIP mode you can use any of the audio modes. However, to achieve
maximum compatibility with other SIP devices you should use a audio mode that is post fixed with (rfc), e.g. G722(rfc).
3/ If you wish to multicast your audio then enter a multicast address and select your audio mode, sample rate. You may only select “Transmit” or “Receive” modes for multicast.
If using the Systembase protocol then it is possible to see the configured link state provided that the remote IP address is correct and the remote codec is configured correctly then the “Link State” will display “OK (2ms)” for example. The time displayed here represents the round trip IP packet delay to the remote codec and back.
If the “link State” is “OK” then you can connect to the remote codec by pressing either the
associated “Auto ON” button or the “Manual” button. Once connected, an entry will appear in the “Active connections” panel as shown above.
AUTO ON allows you to establish a non volatile connection. If the unit it power cycled the unit will automatically reconnect. Note that the far end codec cannot force a disconnect in this mode.
MANUAL allows you to establish a normal connection that can be disconnected from either end of the link. This function is volatile.
The Active connections panel will now display the name of the remote codec together with the it's public IP address. This panel will also confirm the audio mode of the connection. If using
Systembase protocol the “RMT-Q” field will show the active length of the remote codec’s receive buffer for monitoring QOS.
IP LINK 2: ASYMETRICAL AUDIO CONNECTIONS
The C510ip audio codec allows transmit and receive feed to concurrently support different audio formats. So with the correct configuration you can establish a duplex link with different sample rates and audio modes. The screen capture below shows a typical configuration that would achieve this.
In this example the transmit stream is Systembase protocol, G722 Mono whilst the receive stream is SIP protocol APTX stereo and 48KHz sample rate.
THE STATS PAGE
To access the Audio Stats you can select the TAB labelled “IP Audio Statistics”
The Stats page will show show the both the local and remote stats for all active connection's. The statistics as accumulative and can be reset to zero using the associated “RST” button.
STATIC IP ADDRESS:
In most situations it is preferable to have at least one codec using a static IP address so that it’s IP address is always known by roaming codec’s that wish to connect. This can be achieved by configuring the associated DHCP server (router) with the codec’s MAC addresses and enabling port forwarding. In this scenario the routers DHCP server associates a user defined IP address with a given MAC address so when a piece of equipment with a matching MAC address is connected to the local network, the DHCP server always allocates the same IP address.
To determine the MAC address of the codec select “About” TAB.
STATIC IP ADDRESS: NETGEAR DG384 ROUTER
1/ Go to the “LAN IP setup” menu and select “add”. Now configure an address reservation by adding the MAC address of the codec and assigning a suitable IP address. Finish by clicking OK and the address reservation table will confirm both the MAC and IP addresses of the codec.
PORT FORWARDING: GENERAL
To operate on a WAN one end of the link will require port forwarding to be configured on the router. Without port forwarding, packet’s that arrive at the local router will be dropped as the router will not know which internal IP address to forward them to. With port forwarding, specific ports, namely 5000 and 5001 for the C500ip, can be associated with the IP address of a codec on the internal LAN. So when a packet arrives at the router for ports 5000 or 5001, the configured router will automatically forward these packets onto the associated internal IP address.
NOTE: the calling codec will not require port forwarding to be configured as the process of connecting to the “configured end” will force the local routers ports to open.
PORT FORWARDING: NETGEAR DG384 ROUTER
Go to the Services menu and configure a service for the C510ip ports 5000 and 5001.
Note for SIP you will need to repeat the above process for ports 5060 and the chosen audio port number (5050 default).
Next, go to the Firewall Rules menu and create an inbound service for the C510ip. In this example the data on ports 5000 and 5001 will be forwarded onto the internal static IP address 198.0.0.61
NOTE: If quality of service is required then the codec support DSCP tagging. This will allow the network router to identify the IP audio stream and route the packets in a higher audio queue.
