art, musycc - Accoom Networks Artery T1/E1 network device
musycc* at pci?
art* at musycc?
The art device driver supports the Accoom Networks Artery Series Network
cards. This includes the following models:
Accoom Artery Single T1/E1 PCI
Accoom Artery Dual T1/E1 PCI
The following media types (as given to ifconfig(8)) are supported:
media T1 Set T1, B8ZS ESF operation.
media T1-AMI Set T1, AMI SF operation.
media E1 Set E1, HDB3, G.703 clearchannel operation.
media E1-G.704 Set E1, HDB3, G.704 structured operation without
media E1-G.704-CRC4 Set E1, HDB3, G.704 structured operation with
If no media type is set, the art driver places the card into E1-G.704-
The art driver supports the following media options for all available
mediaopt ppp Use PPP line protocol.
If no media options are set, the card defaults to cHDLC (Cisco High-Level
Data Link Control) with 32-bit HDLC CRC checksum.
It is possible to change the timeslot range for the following media
If no timeslots are configured, the art driver configures the card to use
all possible channels. Use ifconfig(8) to change the timeslot range.
Enable all possible channels for this card:
# ifconfig art0 timeslot all
Enable channels 1-31 for this card:
# ifconfig art0 timeslot 1-31
Enable channels 1-15, 16-31 for this card:
# ifconfig art0 timeslot 1-15,16-31
It is possible to change the clock mode of the interface with
ifconfig(8). To use the internal clock as clock source for the line, use
master mode. For example:
# ifconfig art0 media E1-G.704 mode master
The default mode recovers the clock from the incoming line signal. This
can be explicitly set by using the autoselect mode. For example:
# ifconfig art0 media E1-G.704 mode autoselect
art%d: device timeout The device has stopped responding to the network
art%d: internal FIFO underflow The internal FIFO got empty while
transmitting a packet. This may indicate a PCI bus congestion.
art%d: internal FIFO overflow The internal FIFO overflowed while
receiving a packet. This may indicate a PCI bus congestion.

The art device driver first appeared in OpenBSD 3.8.
