isdnPLCI -- ISDN Physical Link Connection Identifier parameter

Synopsis

   #include <sys/types.h>
   #include <sys/scoisdn.h>
   
   typedef isdnDword_t isdnPLCI_t;

Description

The isdnPLCI (Physical Link Connection Identifier) parameter describes a physical connection between two endpoints. The PLCI is given by the ISDN driver during the creation of the physical connection. This parameter is a dword with a range from 1 to 255 (0 reserved), and also includes the controller:

0 0 PLCI Ex./Int. Controller

31 16 8 7 6 0

0	0	PLCI	Ex./Int.	Controller
31	16	8	7	6 0
