-Implementing a Channel
-======================
-
-* What is a channel?
-
-A channel is a unit which brings in a call to the Asterisk PBX.  A channel
-could be connected to a real telephone (like the Internet Phone Jack) or
-to a logical call (like an Internet phone call).  Asterisk makes no
-distinction between "FXO" and "FXS" style channels (that is, it doesn't
-distinguish between telephone lines and telephones).
-
-Every call is placed or received on a distinct channel.  Asterisk uses a
-channel driver (typically named chan_xxx.so) to support each type of
-hardware.
-
-* What do I need to create a channel?
-
-In order to support a new piece of hardware you need to write a channel
-driver.  The easiest way to do so is to look at an existing channel driver
-and model your own code after it.  
-
-* What's the general architecture?
-
-Typically, a channel reads a configuration file on startup which tells it
-something about the hardware it's going to be servicing.  Then, it
-launches a thread which monitors all the idle channels (See the chan_modem
-or the chan_ixj for an example of this).  When a "RING" or equivalent is
-detected, the monitoring thread should allocate a channel structure and
-assign all the callbacks to it (see ixj_new, for example), and then call
-ast_pbx_start on that channel.  ast_pbx_start will launch a new thread to
-handle the channel as long as the call is up, so once pbx_start has
-successfully been run, the monitor should no longer monitor that channel.
-The PBX thread will use the channel, reading, writing, calling, etc., and
-multiplexing that channel with others using select() on the channel's
-file descriptor (if your channel doesn't have an associated file
-descriptor, you'll need to emulate one somehow, perhaps along the lines of
-what the translator API does with its channel.  
-
-When the PBX is finished with the line, it will hang up the line, at which
-point it the hardware should again be monitored by the monitoring thread.
