<div class="sectionbody" style="max-width:45em">

A PHY link is a physical connection / link towards a given PHY.
This might be, for example,
</span>
<ul class="">
<li>
<span>
a set of file descriptors to device nodes in the /dev/ directory
(sysmobts, litecell15)
</span>
</li>
<li>
<span>
a packet socket for sending raw Ethernet frames to an OCTPHY
</span>
</li>
<li>
<span>
a set of UDP sockets for interacting with OsmoTRX
</span>
</li>
</ul>
</li>
<li>
<span>
Each PHY links has a set of attribute/parameters and a list of 1 to n PHY instances.
</span>
</li>
<li>
<span>
PHY links are numbered 0..n globally inside OsmoBTS.
</span>
</li>
<li>
<span>
Each PHY link is configured via the VTY using its individual top-level
vty node.
</span>
</li>
<li>
<span>
The PHY links and instances must be configured above the BTS/TRX nodes in the configuration file. If the file is saved via the VTY, the code automatically ensures this.
</span>
</li>
</ul>
</div>
</div>
<div class="sect1 slide">
<h1 id="_phy_instance">PHY instance</h1>
<div class="sectionbody" style="max-width:45em">
<ul class="">
<li>
<span>
A PHY instance is an instance of a PHY, accessed via a PHY link.
</span>
</li>
<li>
<span>
In the case of osmo-bts-sysmo and osmo-bts-trx, there is only one
instance in every PHY link. This is due to the fact that the API
inside that PHY link does not permit for distinguishing multiple
different logical TRXs.
</span>
</li>
<li>
<span>
Other PHY implementations like the OCTPHY however do support addressing multiple PHY instances via a single PHY link.
</span>
</li>
<li>
<span>
PHY instances are numbered 0..n inside each PHY link.
</span>
</li>
<li>
<span>
Each PHY instance is configured via the VTY as a separate node beneath each PHY link.
