SCONFIG(8)		FreeBSD	System Manager's Manual		    SCONFIG(8)

     sconfig --	channel	configuration utility for Cronyx adapters

     sconfig [-aimsxeftuc] [device name] [data rate options]
	     [protocol options ...] [interface options ...]

     The sconfig utility is used for configuring the channel options of	the
     Cronyx adapters. In asynchronous mode all the parameters should be	set by
     standard stty(1) utility, with sconfig you	could set only few of them
     (see below).

     Some of the options could be set only on free channels, that is the cor-
     responding	network	interface in down state	in the synchronous mode, and
     in	the asynchronous mode the asynchronous terminal	device /dev/tty*

     Other channel options could be changed ``on the fly''.  Generally,	the
     channel options are set up	during the operating system startup, for exam-
     ple from the /etc/rc file.

     Note, that	not all	options	have a sense for every particular case,	and an
     attempt to	set some of them can hang up the channel or the	whole adapter.

   Information options
     You can specify only one of these options.	If information option is spec-
     ified, sconfig will show corresponding information	and will ignore	all
     other options, except device name.	See also description of	the device

     <none>	 This will show	settings of the	channel.

     -a		 Print all settings of the channel.

     -i		 Print interface settings, equal to the	output of ifconfig(1)

     -m		 Print modem signal status. The	description of all signals can
		 be found in any document related to the modems. Only LE sig-
		 nal should be described. If this signal is On,	than some what
		 use channel. If it is Off, than channel is free.

     -s		 Print brief channel statistics. This is general statistics.
		 See also -x , -e , -f , -t and	-u options. For	the descrip-
		 tion of output, see below.

		 This statistics is very useful	if something goes wrong. For
		 example, if you have no any interrupts, than you use inter-
		 rupt that is not registered in	BIOS for use with ISA bus.

     -x		 Print full channel statistics.	This options allows to see
		 some more counters, but with less precision than with -s

     -e		 Print brief E1/G703 statistics. If you	select this option,
		 you will get statistics accumulated for period	of time	equal
		 to 15 minutes.	For the	description of output, see below.

     -f		 Print full E1/G703 statistics.	This option shows all E1/G703
		 statistics that shows previous	option(	-e ), but also total
		 statistics for	whole period of	time and statistics for	24
		 hours (if available). For the description of output, see

     -t		 Print brief E3/T3/STS-1 statistics. If	you select this
		 option, you will get statistics accumulated for period	of
		 time equal to 15 minutes. For the description of output, see

     -u		 Print full E3/T3/STS-1	statistics. This option	shows all
		 E3/T3/STS-1 statistics	that shows previous option( -t ), but
		 also total statistics for whole period	of time	and statistics
		 for 24	hours (if available). For the description of output,
		 see below.

     -c		 Cleans	all kind of statistics.

   Device selection
     Device is equal to	the name of the	interface that is used for a name of
     the interface that	is sees	ifconfig. The channel number depends on	the
     order of loading drivers by the system.  Some times people	confuse	chan-
     nel number	and adapter number because of the same spelling. Adapter num-
     ber appears in kernel context, channel number in configuration context.

     <none>	 You can omit device name only if you want to get information.
		 This will cause printing information about all	available
		 channels of Cronyx adapters. In the case you want to make
		 some settings you MUST	specify	device name.

     cx##	 This is the channel name for the Sigma	family of Cronyx
		 adapters. (ISA	bus)

     ct##	 This is the channel name for the Tau family of	Cronyx
		 adapters. (ISA	bus)

     cp##	 This is the channel name for the Tau-PCI family of Cronyx
		 adapters. (PCI	bus)

     ce##	 This is the channel name for the Tau32-PCI family of Cronyx
		 adapters. (PCI	bus)

   Data	rate options
     value	 If case of nonzero value it will cause	setting	data rate to
		 given value and setting the internal clock source of the syn-
		 chronization (in synchronous mode).  Zero value is equal to
		 the extclock. The transmitted data (TXD) are synchronized
		 using the internal on-board timing generator, the internally
		 generated timing signal is driven on the TXCOUT pin, and the
		 signal	on the TXCIN pin is ignored. This mode is used for
		 direct	terminal-to-terminal communication, e.g. for connect-
		 ing two computers together in a synchronous mode via rela-
		 tively	short cable.  This method should also be used for
		 testing channels with an external loopback connector.

     extclock	 Set the external timing clock source of synchronous channels.
		 External clock	mode is	the most common	method for connecting
		 external modem	hardware. In this mode the external timing
		 signal	is received on TXCIN pin of the	connector, and it is
		 used as a synchronization clock for transmitting data (TXD).

   Protocol options
     Note. These option	could be set only if channel is	free and they requires
     specifying	of the device name.

     async	 Set asynchronous protocol (or mode). In this mode Cronyx
		 adapters behave as a usual serial devices and you may work
		 with them using usual serial utilities.  All asynchronous
		 settings are performed	via serial configuration utilities.
		 With sconfig you may set only a few of	them. See also
		 stty(1).  (Only for Sigma family)

     cisco	 Set the Cisco HDLC synchronous	protocol.

     fr		 Set the Frame Relay synchronous protocol (ANSI	T1.617 Annex

     ppp	 Set the PPP synchronous protocol. Parameters to the PPP could
		 be set	by the command spppcontrol(1).

     keepalive=on, keepalive=off
		 Turns on/off sending keepalive	messages. This option is used
		 only for synchronous PPP. If this option is on, than PPP will
		 periodically send echo-request	messages. If it	would not
		 receive any echo-reply	messages for some (definite) period of
		 time it will break connection.	It is used for tracking	line

     idle	 You are using NETGRAPH. Protocol depends on connected module.

   Interface options
     Not all of	these options could be set on running channel and not all of
     them are suits to all kind	of adapters/channels. In all dual state
     options off is default value. All this options is not applicable in asyn-
     chronous mode, except debug option.

     port=rs232, port=v35, port=rs449
		 Set port type for old Sigma models.

     cfg=A, cfg=B, cfg=C
		 Set configuration for the adapter. This option	could be set
		 only for Tau/E1 and Tau/G703 and only if all channels are not
		 running.  cfg=A - Two independent E1/G703 channels. This is
		 default setting.  cfg=B (Only for ISA models) - For Tau/G703
		 this mean one G703 channel and	one digital channel.  For
		 Tau/E1	first physical channel divides on to subchannels. One
		 of them goes to the first logical channel and another one
		 goes to the second physical channel. Second (logical) channel
		 is digital channel.  cfg=C - This configuration is used only
		 for E1	models.	In this	case first physical channel consists
		 of three data flows. Two of them go to	two (logical) chan-
		 nels. The last	one goes to the	second physical	channel. On
		 new models (Tau32-PCI,	Tau-PCI/2E1 and	Tau-PCI/4E1) this con-
		 figuration means single source	of synchronization and passing
		 all unused (in	both channels) timeslots from one channel to
		 other.	For the	detailed description of	the configuration see
		 your documentation to the adapter. This option	could not be
		 set on	running	channel.

     loop=on, loop=off
		 Turn on/off internal loopback.	This mode is useful for	test-
		 ing. Switch on	this option and	try to send something. If you
		 have no any interrupt,	than, probably,	you forgot to switch
		 using IRQ for PCI to ISA bus. Check your BIOS settings.

     rloop=on, rloop=off (Only for Tau32-PCI and Tau-PCI/E3)
		 Turn on/off remote loopback. This mode	is also	useful for

     dpll=on, dpll=off
		 Turn on/off digital phase locked loop mode (DPLL). When
		 enabled, the receiver timing clock signal is derived from the
		 received data.	Must be	used with NRZI encoding, to avoid the
		 synchronization loss.

     nrzi=on, nrzi=off
		 Turn on/off nrzi encoding. In off state nrz encoding is used.
		 NRZ - the zero	bit is transmitted by the zero signal level,
		 the one bit - by the positive signal level. NRZI - the	bit
		 number	zero is	transmitted by the change of the signal	level,
		 the one bit - by the constant signal level. Commonly is used
		 with dpll=on option.

     invclk=on,	invclk=off
		 Invert	the both transmit and receive clock signals (Tau and
		 Tau-PCI only).

     invrclk=on, invrclk=off
		 Invert	the receive clock signals (Tau-PCI only).

     invtclk=on, invtclk=off
		 Invert	the transmit clock signals (Tau-PCI only).

     higain=on,	higain=off
		 Turn on/off increasing	the E1 receiver	non linear sensitivity
		 to -30	dB (E1 only). In of state the sensitivity is -12 dB.
		 This allows increasing	line distance.

     cablen=on,	cablen=off (Only for Tau-PCI/T3	and Tau-PCI/STS-1)
		 Turn on/off adjusting transmit	signal for long	cable

     monitor=on, monitor=off
		 Turn on/off increasing	the E1 receiver	lines sensitivity to
		 -30 dB	(Tau32-PCI, Tau-PCI/2E1	and Tau-PCI/4E1	only). This
		 could be used for interception	purposes.

     phony=on, phony=off
		 Turn on/off the so-called phony mode (Tau32-PCI and Tau-PCI
		 E1 family only). This mode allows receiving raw CEPT frames
		 from E1 line. Raw frames could	be accessed, for example, via
		 raw protocol. Packets would come at rate of 500 frames	per
		 second	with length 16xN (for Tau-PCI/E1 model), where N is
		 the number of timeslots. For Tau-PCI/2E1 and Tau-PCI/4E1 N
		 should	be equal to 32 independently from number of used

     unfram=on,	unfram=off
		 Turn on/off unframed mode (Tau32-PCI, Tau-PCI/2E1 and Tau-
		 PCI/4E1 only).	 unfram=on switches channel to unframed	G.703
		 mode.	unfram=off switches channel to framed E1 (G.704	mode).

     scrambler=on, scrambler=off
		 Turn on/off the scrambling of G.703 data (Tau32-PCI, Tau-
		 PCI/G.703 and Tau-PCI/2E1, Tau-PCI/4E1	in unframed mode

     use16=on, use16=off
		 Turn on/off the usage of 16-th	timeslot for data transmission
		 (Tau32-PCI and	Tau-PCI	E1 family only).  Normally 16-th
		 timeslot is used for signaling	information (multiframing

     crc4=on, crc4=off
		 Turn on/off CRC4 superframe mode (E1 only).

     syn=int, syn=rcv, syn=rcv0, syn=rcv1, syn=rcv2, sync=rcv3
		 int - use an internal clock generator for G703	transmitter
		 (clock	master).  rcv -	use the	G703 receiver data clock as
		 the transmit clock (clock slave).  rcv0, rcv1,	rcv2, rcv3 -
		 use the G703 receiver clock of	the other channel (E1 models

		 Binds logical channel to the physical channel (Tau32-PCI,
		 Tau-PCI/2E1 and Tau-PCI/4E1 only). Using this parameter you
		 could,	for example, split E1 physical channel into several

		 Set up	the list of timeslots to use by	the channel (E1	only).
		 The timeslots are numbered from 1 to 31, and are separated by
		 comma or minus	sign, giving an	interval. For example:

		 Set up	the list of timeslots, translated to the E1 subchannel
		 in cfg=B and cfg=C configurations (Tau/E1 only).

     debug=0, debug=1, debug=2
		 Turn on/off debug messages.  0	- turn off debug messages.  1
		 - turn	on debug messages, equal to the	debug option to	the
		 ifconfig(8) utility.  2 - high	intensive debug	message,
		 developers only.

     Set up the	channel	1 for use with the HDSL	modem or any other synchronous
     leased-line modem,	and PPP/HDLC protocol (for Sigma):

	   sconfig cx1 ppp extclock
	   ifconfig cx1 up

     Set up the	channel	0 of Tau/E1 for	use with the Cisco protocol over E1
     link, with	the single virtual connection.	The DLCI number	is detected
     automatically.  Use timeslots 1-10:

	   sconfig ct0 cisco ts=1-10
	   ifconfig ct0 up

     Set up the	channel	0 for the synchronous null-modem link to the nearby
     computer, internal	clock source, 256000 bits/sec, protocol	Cisco/HDLC
     (for Tau):

	   sconfig ct0 cisco 256000
	   ifconfig ct0 up

     Set up the	channel	1 for the leased line link using data-only null-modem
     cable (or modems like Zelax+ M115). Synchronous DPLL mode,	128000
     bits/sec, protocol	PPP/HDLC, NRZI encoding	(for Sigma):

	   sconfig cx1 ppp 128000 nrzi=on dpll=on
	   ifconfig cx1 up

     This section contains description of abbreviations	used by	sconfig	while
     displaying	various	statistics. For	description of options connected with
     statistics	see above.

     When running, the driver gathers the statistics about the channels, which
     could be accessed via sconfig utility or by ioctl(2) call SERIAL_GETSTAT.

     Rintr	 The total number of receive interrupts.

     Tintr	 The total number of transmit interrupts.

     Mintr	 The total number of modem interrupts.

     Oerrs The number of transmit errors.

   E1/G.703 Statistics
     For E1 and	G.703 channels the SNMP-compatible statistics data are gath-
     ered (see RFC 1406). It could be accessed via sconfig utility or by
     ioctl(2) call SERIAL_GETESTAT.

     Unav (uas)	 Unavailable seconds - receiving all ones, or loss of carrier,
		 or loss of signal.

     Degr (dm)	 Degraded minutes - having error rate more than	10e-6, not

   E1/G.703 Status
     sconfig utility also prints the E1/G.703 channel status. The status could
     have the following	values (nonexclusive):

     Ok		 The channel is	in valid state,	synchronized.

     TSTERR	 Test error (G.703 only).

     stty(1) ioctl(2) sppp(4) spppconrol(8) ifconfig(8)	route(8)

     This utility is a replacement of utilities	cxconfig and ctconfig that was
     used in past with FreeBSD drivers.	Those two utilities and	the present
     utility are not compatible. And therefore all scripts should be rewrit-
     ten. More over, Linux and FreeBSD version of present utility not fully

     All software produced by Cronyx Engineering is thoroughly tested. But as
     created by	the man	it can contain some `BUGS'.  If	you have caught	one,
     try to localize it	and send a letter with description of this bug and all
     operation that you	have done. We will try to reproduce an error and fix
