## Zaptel Configuration File## This file is parsed by the Zaptel Configurator, ztcfg### First come the span definitions, in the format# span=<span num>,<timing>,<line build out (LBO)>,<framing>,<coding>[,yellow]# # The timing parameter determines the selection of primary, secondary, and# so on sync sources. If this span should be considered a primary sync# source, then give it a value of "1". For a secondary, use "2", and so on.# To not use this as a sync source, just use "0"## 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 zapdel 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.# "nethdlc" : The zaptel driver bundles the channels together into an# hdlc network device, which in turn can be configured with# sethdlc (available separately).# "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#loadzone = us#loadzone = us-old#loadzone=gr#loadzone=it#loadzone=fr#loadzone=de#loadzone=uk#loadzone=fi#loadzone=jp#loadzone=sp#loadzone=nodefaultzone=us
