# Zaptel Configuration File
#
# This file is parsed by the Zaptel Configurator, ztcfg
#
#
# First come the span definitions, in the format
# span=<span num>,<timing source>,<line build out (LBO)>,<framing>,<coding>[,yellow]
#
# All T1/E1 spans generate a clock signal on their transmit side. The
# <timing source> parameter determines whether the clock signal from the far
# end of the T1/E1 is used as the master source of clock timing. If it is, our
# own clock will synchronise to it. T1/E1's connected directly or indirectly to
# a PSTN provider (telco) should generally be the first choice to sync to. The
# PSTN will never be a slave to you. You must be a slave to it.
#
# Choose 1 to make the equipment at the far end of the E1/T1 link the preferred
# source of the master clock. Choose 2 to make it the second choice for the master
# clock, if the first choice port fails (the far end dies, a cable breaks, or
# whatever). Choose 3 to make a port the third choice, and so on. If you have, say,
# 2 ports connected to the PSTN, mark those as 1 and 2. The number used for each
# port should be different.
#
# If you choose 0, the port will never be used as a source of timing. This is
# appropriate when you know the far end should always be a slave to you. If the
# port is connected to a channel bank, for example, you should always be its
# master. Any number of ports can be marked as 0.
#
# Incorrect timing sync may cause clicks/noise in the audio, poor quality or failed
# faxes, unreliable modem operation, and is a general all round bad thing.
#
# The line build-out (or LBO) is an integer, from the following table:
# 0: 0 db (CSU) / 0-133 feet (DSX-1)
# 1: 133-266 feet (DSX-1)
# 2: 266-399 feet (DSX-1)
# 3: 399-533 feet (DSX-1)
# 4: 533-655 feet (DSX-1)
# 5: -7.5db (CSU)
# 6: -15db (CSU)
# 7: -22.5db (CSU)
#
# The framing is one of "d4" or "esf" for T1 or "cas" or "ccs" for E1
#
# Note: "d4" could be referred to as "sf" or "superframe" 
#
# The coding is one of "ami" or "b8zs" for T1 or "ami" or "hdb3" for E1
#
# E1's may have the additional keyword "crc4" to enable CRC4 checking
#
# If the keyword "yellow" follows, yellow alarm is transmitted when no
# channels are open.
#
#span=1,0,0,esf,b8zs
#span=2,1,0,esf,b8zs
#span=3,0,0,ccs,hdb3,crc4
#
# Next come the dynamic span definitions, in the form:
# dynamic=<driver>,<address>,<numchans>,<timing>
#
# Where <driver> is the name of the driver (e.g. eth), <address> is the
# driver specific address (like a MAC for eth), <numchans> is the number
# of channels, and <timing> is a timing priority, like for a normal span.
# use "0" to not use this as a timing source, or prioritize them as
# primary, secondard, etc.  Note that you MUST have a REAL zaptel device
# if you are not using external timing.
#
# dynamic=eth,eth0/00:02:b3:35:43:9c,24,0
#
# Next come the definitions for using the channels.  The format is:
# <device>=<channel list>
#
# Valid devices are:
#
# "e&m"     : Channel(s) are signalled using E&M signalling (specific
#             implementation, such as Immediate, Wink, or Feature Group D
#             are handled by the userspace library).
# "fxsls"   : Channel(s) are signalled using FXS Loopstart protocol.
# "fxsgs"   : Channel(s) are signalled using FXS Groundstart protocol.
# "fxsks"   : Channel(s) are signalled using FXS Koolstart protocol.
# "fxols"   : Channel(s) are signalled using FXO Loopstart protocol.
# "fxogs"   : Channel(s) are signalled using FXO Groundstart protocol.
# "fxoks"   : Channel(s) are signalled using FXO Koolstart protocol.
# "sf"	    : Channel(s) are signalled using in-band single freq tone.
#		Syntax as follows: 
#		 channel# => sf:<rxfreq>,<rxbw>,<rxflag>,<txfreq>,<txlevel>,<txflag>
#		rxfreq is rx tone freq in hz, rxbw is rx notch (and decode)
#		bandwith in hz (typically 10.0), rxflag is either 'normal' or
#		'inverted', txfreq is tx tone freq in hz, txlevel is tx tone 
#		level in dbm, txflag is either 'normal' or 'inverted'. Set 
#		rxfreq or txfreq to 0.0 if that tone is not desired.
# "unused"  : No signalling is performed, each channel in the list remains idle
# "clear"   : Channel(s) are bundled into a single span.  No conversion or
#             signalling is performed, and raw data is available on the master.
# "indclear": Like "clear" except all channels are treated individually and
#             are not bundled.  "bchan" is an alias for this.
# "rawhdlc" : The zaptel driver performs HDLC encoding and decoding on the 
#             bundle, and the resulting data is communicated via the master
#             device.
# "fcshdlc" : The zaptel (software) driver performs HDLC encoding and decoding on the
#             bundle and also performs incoming and outgoing FCS insertion
#             and verification.  "dchan" is an alias for this.
# "hardhdlc" : The hardware driver performs HDLC encoding and decoding on the
#             bundle and also performs incoming and outgoing FCS insertion
#             and verification.  Is subject to limitations and support of underlying
#             hardware.
# "nethdlc" : The zaptel driver bundles the channels together into an
#             hdlc network device, which in turn can be configured with
#             sethdlc (available separately). In 2.6.x kernels you can also optionally
#             pass the name for the network interface after the channel list.
#             Syntax:
#               nethdlc=<channel list>[:interface name]
#             Use original names, don't use the names which have been already registered 
#             in system e.g eth.
#
# "dacs"    : The zaptel driver cross connects the channels starting at
#             the channel number listed at the end, after a colon
# "dacsrbs" : The zaptel driver cross connects the channels starting at
#             the channel number listed at the end, after a colon and 
#             also performs the DACSing of RBS bits
#
# The channel list is a comma-separated list of channels or ranges, for
# example:
#
#   1,3,5 (channels one, three, and five)
#   16-23, 29 (channels 16 through 23, as well as channel 29
#
# So, some complete examples are:
#   e&m=1-12
#   nethdlc=13-24
#   fxsls=25,26,27,28
#   fxols=29-32
#
#fxoks=1-24
#bchan=25-47
#dchan=48
#fxols=1-12
#fxols=13-24
#e&m=25-29
#nethdlc=30-33
#clear=44
#clear=45
#clear=46
#clear=47
#fcshdlc=48
#dacs=1-24:48
#dacsrbs=1-24:48
#
# Finally, you can preload some tone zones, to prevent them from getting
# overwritten by other users (if you allow non-root users to open /dev/zap/*
# interfaces anyway.  Also this means they won't have to be loaded at runtime.
# The format is "loadzone=<zone>" where the zone is a two letter country code.
# 
# You may also specify a default zone with "defaultzone=<zone>" where zone
# is a two letter country code.
#
# An up-to-date list of the zones can be found in the file zaptel/zonedata.c

# Section for PCI Radio Interface 
# (see http://www.zapatatelephony.org/app_rpt.html)
#
# The PCI Radio Interface card interfaces up to 4 two-way radios (either
# a base/mobile radio or repeater system) to Zaptel channels. The driver
# may work either independent of an application, or with it, through
# the driver;s ioctl() interface. This file gives you access to specify
# load-time parameters for Radio channels, so that the driver may run
# by itself, and just act like a generic Zaptel radio interface.
#
# Unlike the rest of this file, you specify a block of parameters, and
# then the channel(s) to which they apply. CTCSS is specified as a frequency
# in tenths of hertz, for example 131.8 HZ is specified as 1318. DCS
# for receive is specified as the code directly, for example 223. DCS for
# transmit is specified as D and then the code, for example D223.
#
# The hardware supports a "community" CTCSS decoder system that has
# arbitrary transmit CTCSS or DCS codes associated with them, unlike
# traditional "community" systems that encode the same tone they decode.
# 
# this example is a single tone DCS transmit and receive
#
# # specify the transmit tone (in DCS mode this stays constant)
# tx=D371
# # specify the receive DCS code
# dcsrx=223
#
# this example is a "community" CTCSS (if you only want a single tone, then
# only specify 1 in the ctcss list)
#
# # specify the default transmit tone (when not receiving)
# tx=1000
# # Specify the receive freq, the tag (use 0 if none), and the transmit code.
# # The tag may be used by applications to determine classification of tones.
# # The tones are to be specified in order of presedence, most important first.
# # Currently, 15 tones may be specified..
# ctcss=1318,1,1318
# ctcss=1862,1,1862
#
# The following parameters may be omitted if their default value is acceptible
#
# # set the receive debounce time in milliseconds
# debouncetime=123
# # set the transmit quiet dropoff burst time in milliseconds
# bursttime=234
# # set the COR level threshold (specified in tenths of millivolts)
# # valid values are {3125,6250,9375,12500,15625,18750,21875,25000}
# corthresh=12500
# # Invert COR signal {y,n}
# invertcor=y
# # set the external tone mode; yes, no, internal {y,n,i}
# exttone=y
#
# Now apply the configuration to the specified channels:
#
# # We are all done with our channel parameters, so now we specify what
# # channels they apply to
# channels=1-4
