Downloading VoIP Firmware

If you have installed an AT-AR027 VoIP PIC, you now need to download and install the VoIP firmware onto your PIC. Before you begin, check that the PIC Error LED on the PIC is off, and that the PIC has been recognised by your switch or router, using the show system command.

1.Download the VoIP PIC firmware.

Point your web browser at www.alliedtelesis.com/support/software/. Navigate to the PIC product information page and find the firmware files you need from the support page. You will need:

•the PIC boot code, which is responsible for loading the protocol image onto the PIC

•the images for the protocols you wish to run on the PIC—SIP and/or H.323 Download the firmware files you need and save them to your TFTP server.

2.Load the boot code onto your switch or router.

To load the boot code from your TFTP server, use the command:

load method=tftp destination=flash server={hostnameipadd}

file=filename

3.If possible, load the protocol image onto your switch or router.

If you have enough space, load the protocol image onto your switch or router’s flash, so that it does not need to be continually connected to an external TFTP server. Use the load command as described above.

4.Set the boot code and protocol image.

To set the boot code on the switch or router, use the command: set voip bootcode=filename server={ipaddflash}

This command sets the boot code filename, and specifies the location of the protocol image that the boot code will load.

To set the name of the protocol image (file), and specify what type of VoIP protocol the protocol image supports, use the command:

set voip file=filename protocol={h323sip} type={fxsfxo}

5.Set the interface for the VoIP traffic.

To set the preferred interface for VoIP traffic, use the command: set voip public interface=interface

If a logical interface is not specified, 0 is assumed (that is, eth0 is equivalent to eth0-0).

The AT-AR021 (U) BRI-U is primarily designed for digital telephony applications, featuring two BRI (Basic Rate Interface) ports. This enables organizations to efficiently connect to ISDN lines, facilitating reliable voice communications. It supports a variety of protocols, ensuring compatibility with numerous telecom networks, which is essential for businesses relying on seamless voice integration.

The AT-AR022 ETH is a versatile solution that focuses on enhanced Ethernet connectivity. Designed for high-speed data transmission, it supports multiple VLANs (Virtual Local Area Networks) and Quality of Service (QoS) configurations. This ensures that critical applications receive the bandwidth they need while providing efficient network traffic management.

For organizations requiring enhanced Ethernet capabilities, the AT-AR026 4ETH offers four Ethernet ports, providing flexibility for multiple devices to connect simultaneously. This model is particularly beneficial for small to medium-sized enterprises looking to develop a robust local area network (LAN) without extensive infrastructural changes. Its ability to support power over Ethernet (PoE) enables it to power devices like VoIP phones and security cameras directly through the network cable, simplifying deployment and reducing clutter.

The AT-AR023 SYN model is tailored for synchronous communication, making it ideal for applications that demand constant data flow and real-time processing. Its advanced synchronization technology ensures minimal latency and maximum throughput, critical for industries such as finance and telecommunications, where precise timing is essential for operations.

Finally, the AT-AR024 ASYN4 caters to asynchronous communication applications. This device supports four asynchronous serial ports, enabling connectivity with a wide range of equipment, including legacy systems, smart devices, and industrial machinery. It serves as a bridge for organizations transitioning from traditional systems to modern networking paradigms.

In summary, Allied Telesis offers a diverse portfolio of networking solutions through the AT-AR021 (U) BRI-U, AT-AR022 ETH, AT-AR026 4ETH, AT-AR023 SYN, and AT-AR024 ASYN4. Each model embodies unique features and technologies designed to enhance connectivity, ensure compatibility, and facilitate seamless communication across various platforms, making them essential components for contemporary network infrastructures.
