SCONFIG(8) FreeBSD System Manager's Manual SCONFIG(8) NAME sconfig -- channel configuration utility for Cronyx adapters SYNOPSIS sconfig [-aimsxeftuc] [device name] [data rate options] [protocol options ...] [interface options ...] DESCRIPTION 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* closed. 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 name. <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) command. -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 option. -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 below. -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 below. -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 D). 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 state. 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 testing. 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 T3/STS-1. 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 timeslots. 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 only). 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 CAS). 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 only). dir=<number> 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 channels. ts=interval 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: "ts=1-3,5,17". pass=interval 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. EXAMPLES 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 158.250.244.2 158.250.244.1 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 158.250.244.2 158.250.244.1 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 200.1.1.1 200.1.1.2 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 158.250.244.2 158.250.244.1 up DIAGNOSTICS This section contains description of abbreviations used by sconfig while displaying various statistics. For description of options connected with statistics see above. Statistics 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. Ibytes The total bytes received. Ipkts The total packets received (for HDLC mode). Ierrs The number of receive errors. Obytes The total bytes transmitted. Opkts The total packets transmitted (for HDLC mode). 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 counting unavailable and severely errored seconds. Bpv (bpv) HDB3 bipolar violation errors. Fsyn (fse) Frame synchronization errors (E1 only). CRC (crce) CRC4 errors (E1). RCRC (rcrce) Remote CRC4 errors: E-bit counter (E1).

Sev (ses) Severely errored seconds - 832 or more framing errors, or 2048 or more bipolar violations. Bur (bes) Bursty errored seconds - more than 1 framing error, but not severely errored. Oof (oofs) Severely errored framing seconds - out of frame sync. Slp (css) Controlled slip second -- any slip buffer overflow or under- flow. 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. LOS Loss of sync. AIS Receiving unframed all ones (E1 only). LOF Loss of framing (E1 only). LOMF Loss of multiframing (E1 only). FARLOF Receiving remote alarm (E1 only).

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 compatible. BUGS 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 it.
