CP(4)

NAME

     cp -- driver for synchronous Cronyx Tau-PCI WAN adapters

SYNOPSIS

     device cp

     Additional options:
     device sppp
     options NETGRAPH
     options NETGRAPH_CRONYX

DESCRIPTION

     The cp driver needs either sppp(4) or netgraph(4).  Which one to use is
     determined by the NETGRAPH_CRONYX option.	If this option is present in
     your kernel configuration file, the cp driver will be compiled with
     netgraph(4) support.  Otherwise, it will be compiled with sppp(4) sup-
     port.

     Refer to sconfig(8) for information about the cp adapter configuration.

HARDWARE

     The cp driver supports the following models of Tau-PCI WAN adapters:

     Cronyx Tau-PCI	   V.35 and RS-232 interfaces
     Cronyx Tau-PCI/R	   RS-530(RS-449) and X.21 interfaces
     Cronyx Tau-PCI-E1	   fractional E1 interfaces
     Cronyx Tau-PCI-G703   unframed E1 interfaces
     Cronyx Tau-PCI-2E1    fractional E1 and unframed E1 interfaces
     Cronyx Tau-PCI-4E1    fractional E1 and unframed E1 interfaces
     Cronyx Tau-PCI-E3	   E3 interface
     Cronyx Tau-PCI-T3	   T3 interface
     Cronyx Tau-PCI-STS1   STS-1 interface
