Chapter 2 WLAN Handsets overview 17

Feature options area

When a feature is activated, or when you are on an active call, the Feature options area shows you the action you must take to proceed.

For example: Pswd. This means you must enter your mailbox password.

The Feature options area shows the label for the Ftre soft key and for the three display soft keys. These button labels appear directly above the Feature and display soft keys, and to the right of the Ftre label on the display. These button labels vary, depending on the feature in use.

WLAN handset states

The WLAN Handset can be in one of the states described in the following table.

IMPORTANT!

User MUST end every call

The user 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 this is not done, it will result in the ringer not ringing and you might miss an important call.

Table 3 States of the WLAN Handset

State

Description

 

 

Power off

The handset is turned off. It is not registered with the Call Server.

 

Normally the handset enters the power-off state when the user presses Power Off/

 

End Call for approximately two seconds when the handset is in the standby state.

 

The batteries can be recharged in the power-off state.

 

 

Standby

This is the normal state when the handset is online but inactive. In the standby state, the

 

handset can receive calls and access the User Option menu.

 

To perform other operations, the handset must be active (off-hook).

 

The standby state uses less power than the active (idle) state. The batteries can be

 

recharged in the standby state.

 

When the handset is in the standby state, the programmed extension number is shown in

 

the display area.

 

 

Active

This is equivalent to a regular telephone being off-hook.

(off-hook)

The handset goes to the active (off-hook) state by pressing Power On/Start Call when

 

 

the handset is in the standby or active (idle) states. When in this state, the handset uses a

 

soft ring.

 

 

Active (idle)

This is equivalent to a regular telephone being idle. The active (idle) state is reached in

 

two ways:

 

An incoming call in the Standby state causes the handset to go to the active (idle) state

 

and begin ringing.

 

The user presses FCN and 3 when the handset is in the active (off-hook) state to access

 

the function menu. In this state, the handset does not ring when a call comes in.

 

In the active (idle) state, the handset and access point exchange a small packet

 

approximately once every 15 milliseconds. This increases the power consumption and

 

consumes bandwidth, particularly for the RF portion of the link. Therefore, the handset is

 

not normally left in the active (idle) state except for special situations.

2210, 2211, 2212 specifications

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.
