Mute

While on a call, press and to turn the microphone off.

Press and again to turn the microphone on.

End calls

You must end every call, by pressing the Power Off/End Call key, to release system resources and allow the WLAN Handset to function properly. If you press the Power Off/End Call key, you enable the handset to go to low-power standby mode to conserve battery power.

Push-to-Talk

Push-to-Talk is available on the WLAN Handset 2211 only.

Push-to-Talk mode enables the WLAN Handset 2211 to operate in a group broadcast mode in addition to the standard handset operation. The WLAN Handset 2211 supports eight multicast channels with the current channel saved in the handset memory.

IMPORTANT!

Pressing any other keys or buttons (such as the Up/Down/Select or keypad keys) while in a Push-to-Talk call will terminate the call.

Call period

Push-to-Talk mode operates on the concept of a call period. The Push-to-Talk call period begins with the first transmission and ends when there has been no two-way radio traffic on the channel for 10 seconds.

The Push-to-Talk mode controls the handset keypad during the call period. Therefore, it is not possible to use the keypad for any other functions. However, it is possible to place and receive telephone calls.

Nortel Networks, once a titan in the telecommunications arena, produced a variety of products that were pivotal in shaping the future of communication technologies. Among these products were the Nortel 2212 and 2211, which played a significant role in enterprise environments, particularly in the realm of voice over IP (VoIP) and unified communications.

The Nortel 2212 and 2211 are voice codecs used primarily in voice and video communications. They are built to handle multimedia transmissions over packet-switched networks, enhancing voice clarity and video quality. The 2212 codec is particularly noted for its ability to support a wide range of audio frequencies, which allows it to replicate sounds with greater fidelity. This is crucial in corporate settings where clear communication is imperative.

One of the standout features of both codecs is their ability to support multiple voice channels. The 2212 can handle up to 12 simultaneous voice calls, while the 2211 is optimized for smaller operations and can manage 11 calls effectively. This scalability is essential for businesses of varying sizes, enabling them to grow without needing substantial overhauls to their existing infrastructure.

In terms of technology, the Nortel 2212 and 2211 utilize advanced compression algorithms to minimize bandwidth usage while maintaining high audio quality. This is especially beneficial for organizations operating in areas with limited bandwidth or needing to cut costs related to data transmission. Nortel's technology optimizes the transmission over IP networks, making it suitable for VoIP, video conferencing, and even multimedia content delivery.

Additionally, both codecs are compliant with various standards, which makes them compatible with a wide array of telecommunications equipment. Their interoperability means that businesses can integrate these codecs into existing networks without significant disruptions.

Security is another prominent characteristic of the Nortel 2212 and 2211. With built-in encryption protocols, these devices ensure that voice and video communications remain secure from potential eavesdropping or unauthorized access.

In summary, the Nortel 2212 and 2211 play crucial roles in modern telecommunications, offering robust features like scalability, advanced compression, compatibility, and security. Their legacy continues to influence the development of communication technologies and practices in enterprises around the globe, even as newer systems emerge in the fast-evolving telecom landscape.
