ADEGOKE,
Are you shure that you NEED crc4 enabled on spans? It's
rarely used and improper settings causes E1 link to be
down. When you get link into the operation you should first
receive message that channels have been allocated from
asterisk debug messages. Until then there is no SS7 link
I do use sangoma A102 - and it's working.
My advice to try simple way first. Configure single SS7 link
- when you succeed with it - process furher configuring
more links.
See my working configs below, hopy it can help
I have empty zapata.conf

ZAPTEL.CONF
#
# 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,ccs,hdb3
bchan=1-31
span=2,0,0,ccs,hdb3
bchan=32-62
#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

#
# 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
