# ce(4freebsd)

driver for synchronous Cronyx Tau-PCI/32 WAN adapters

## NAME

**ce** – driver for synchronous Cronyx Tau-PCI/32 WAN adapters

## SYNOPSIS

To compile this driver into the kernel, place the following line in your kernel configuration file:

**device ce**

Alternatively, to load the driver as a module at boot time, place the following line in [loader.conf(5)](/loader.conf/5.md):

```
if_ce_load="YES"
```

Additional options: **device sppp** **options NETGRAPH** **options NETGRAPH\_CRONYX**

## DESCRIPTION

The **ce** driver needs either [sppp(4)](/sppp/4.md) or [netgraph(4)](/netgraph/4.md). Which one to use is determined by the NETGRAPH\_CRONYX option. If this option is present in your kernel configuration file, the **ce** driver will be compiled with [netgraph(4)](/netgraph/4.md) support. Otherwise, it will be compiled with [sppp(4)](/sppp/4.md) support.

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

## HARDWARE

The **ce** driver supports the following models of Tau-PCI/32 WAN adapters:

- Cronyx Tau-PCI/32

  two fractional/unframed E1 interfaces, with 32 HDLC channels shared between them with total adapter throughput 2048 kbps.

- Cronyx Tau-PCI/32-Lite

  single fractional/unframed E1 interface, with 32 HDLC channels.

## HISTORY

The **ce** driver was added in FreeBSD 6.2, FreeBSD 5.5 and FreeBSD 4.11. The **ce** driver for previous versions of FreeBSD is available from *http://www.cronyx.ru/*.
