<h2>What<a id="What is a Channel Group</h2>

<p>A <span class="reference">Channel Group</span> is any group of channels or lines coming into your organisation.</p>

<h2>Adding a Channel Group</h2>

<p>To add a Channel Group to the Directory, simply select <span class="reference">Channel Group</span> from the <span class="reference">Organisation unit</span> list and give it a name that represents its function 
e.g. 'Main Aberdeen ISDN 30' as shown below. Then click <span class="button">Add</span> to put in to your Directory.</p>

<p>There are no limits to the amount of Channel Groups you can add so you can set up all your ISDN, analogue, fax lines and  private circuits exactly as they are on your switch. You simply select the Channel Group, give it a name and press Add.</p>

<p>Please note that a channel group on one site can be linked its counterpart on another site to provide on-net calls. To do this, click on the <span class="reference">Channel Group</span> and select <span class="button">Properties</span>. A screen similar to the following will appear:</p>

<p>Then click on the green add beside Remote end to drill down through directory until you find the channel group you would like to select for the 'B' end. Click on the green tick <img alt="Green tick" title="Green tick" onerror="imageSubtract(this);" onload="imageSubtract(this);" src="/web.ntl?cmd=docs.getimg&amp;i=80026"> when you are ready to choose the 'B' end you would like to create the private circuit relationship with.</p>

<p>This channel group will then be added as the remote end as shown below and calls between sites will be treated as on-net calls, therby eliminating the call duplication often associated with inter site links.</p>
