I have found that keeping the dock plugged into an external monitor, keyboard, and mouse enhances the usability of many applications, and is almost a necessity given the small size of the 7" form factor. Even the video output ports on both the dock and tablet support both VGA and HDMI, one drawback is the low external resolution size, which is limited to 1024x640 pixels.
The CIUS docking station turns the Cisco CIUS into a full Cisco IP phone. The best way to use a Cisco IP phone is to connect it into a Cisco Communications Manager server. The Cisco Communications manager can be the company's entire phone system, and it is currently the #1 shipping business phone system in the world, so there are many organizations that could take advantage of this capability. If an organization has a different phone system, it is still possible to stand up a small Cisco Communications manager installation for just the Cisco CIUS's, and then integrate the Cisco phone system into the company's existing IP or traditional phone system.
The HD video conferencing endpoint capabilities of the CIUS can be enabled by connecting it into the Cisco Communications Manager, but for full HD video conferencing capabilities it is best to have the Cisco Video Infrastructure in place. This provides for standards based video calls to other organizations over the internet, HD video conferences using a centralized conferencing codec, and bandwidth management for the calls.
The Cisco CIUS can be used as a full Virtual Desktop endpoint using either VMware View or Citrix HDX Receiver for Citrix XenApp and XenDesktop. The two virtual desktop applications have their pros and cons, and it is good that the Cisco CIUS supports both. At the 7" form factor when not using the external monitor, the most useful is Citrix XenApp, which provides full screen application capability.
It is important to operate the Cisco CIUS over a good network. Both the Local Area Network and the Wide Area Network has to have a good Quality of Service policy implemented, and there has to be sufficient bandwidth for the voice, video, and virtual desktop streams. The CIUS preferentially uses 802.11n wireless LAN for call control even when docked, so it is best to have a good wireless infrastructure in place that has sufficient coverage, bandwidth, and Quality of Service. The advantage of always using wireless for call control is to allow the user to undock the CIUS in the middle of a video or voice call and to permit it to continue the call without interruption.
The Cisco CIUS is a new category of tablet device that is focused at a distinctly different market than the consumer tablets from Apple and other Android tablet manufacturers. When it is deployed in an enterprise environment that has the right types of back end applications, it can be a very useful device. The two issues of small screen size and low external monitor screen resolution on the 7" CIUS are a limitation for its use as a general purpose tablet. This is overall a good product that works well and can be the main device for a mobile device strategy. It is an especially good choice for organizations that have concerns about security and have existing voice, video, and virtualization deployments. cisco voip phone system, cisco small business
