+Frame Relay (FR) support for linux is built into a two tiered system of device 
+drivers.  The upper layer implements RFC1490 FR specification, and uses the
+Data Link Connection Identifier (DLCI) as it's hardware address.  Usually these
+are assigned by your network supplier, they give you the number/numbers of
+the Virtual Connections (VC) assigned to you.
+
+Each DLCI is a point-to-point link between your machine and a remote one.
+As such, a seperate device is needed to accomodate the routing.  Within the
+net-tools archives is 'dlcicfg'.  This program will communicate with the
+base "DLCI" device, and create new net devices named 'dlci00', 'dlci01'... 
+The configuration script will ask you how many DLCI's you need, as well as
+how many DLCI's you want to assign to each Frame Relay Access Device (FRAD).
+
+The DLCI uses a number of function calls to communicate with the FRAD, all
+of which are stored in the FRAD's private data area.  assoc/deassoc, 
+activate/deactivate and dlci_config.  The DLCI supplies a receive function
+to the FRAD to accept incoming packets.
+
+With this initial offering, only 1 FRAD driver is available.  With many thanks
+to Sangoma Technologies, David Mandelstam & Gene Kozin, the S502A, S502E & 
+S508 are supported.  This driver is currently set up for only FR, but as 
+Sangoma makes more firmware modules available, it can be updated to provide
+them as well.
+
+Configuration of the FRAD makes use of another net-tools program, 'fradcfg'.
+This program makes use of a configuration file (which dlcicfg can also read)
+to specify the types of boards to be configured as FRADs, as well as perform
+any board specific configuration.  The Sangoma module of fradcfg loads the
+FR firmware into the card, sets the irq/port/memory information, and provides
+an initial configuration.
+
+Additional FRAD device drivers can be added as hardware is available.
