Trying to bring up an ss7 link with an Erricson switch using a Digium Te121 card.? Channel 16 the signaling channel seems to be putting out trash possibly the mtp2 bad frame being reported. Here are the current configurations.
?
Zaptel.conf
(have tried the signaling channel dchan=16 and mtp2=16)
?
# Span 1: WCT1/0 "Wildcard TE121 Card 0" (MASTER) HDB3/CCS/CRC4
span=1,1,0,ccs,hdb3,crc4
# termtype: te
bchan=1-15,17-31
mtp2=16
[linkset-siuc]
?
; The linkset is enabled
enabled => yes
?
; The end-of-pulsing (ST) is not used to determine when incoming address is complete
enable_st => no
?
; Reply incoming call with CON rather than ACM and ANM
use_connect => no
?
; The CIC hunting policy (even_mru, odd_lru, seq_lth, seq_htl) is even CIC numbers, most recently used
hunting_policy => even_mru
?
; Incoming calls are placed in the ss7 context in the asterisk dialplan
context => ss7
?
; The language for this context is da
language => us
?
; The value and action for t35. Value is in msec, action is either st or timeout
; If you use overlapped dialling dial plan, you might choose: t35 => 4000,st
t35 => 15000,timeout
?
; The subservice field: national (8), international (0), auto or decimal/hex value
; The auto means that the subservice is obtained from first received SLTM
subservice => 0
?
?
; The host running the mtp3 service
; mtp3server => localhost
?
[link-l1]
?
; This link belongs to linkset siuc
linkset => siuc
?
; The speech/audio circuit channels on this link
channels => 1-15,17-31
?
; The signalling channel
schannel => 16
; To use the remote mtp3 service, use 'schannel => remote,16'
?
; The first CIC
firstcic => 1
?
; The link is enabled
enabled => yes
?
; Echo cancellation
; echocancel can be one of: no, 31speech (enable only when transmission medium is 3.1Khz speech), allways
echocancel => no
; echocan_train specifies training period, between 10 to 100 msec
echocan_train => 350
; echocan_taps specifies number of taps, 32, 64, 128 or 256
echocan_taps => 128

[host-pbx.local]
; chan_ss7 auto-configures by matching the machines host name with the host-<name>
; section in the configuration file, in this case 'gentoo1'. The same
; configuration file can thus be used on several hosts.
?
; The host is enabled
enabled => yes
?
; The point code for this SS7 signalling point is 0x8e0
opc => 0x005a
?
; The destination point (peer) code is 0x3fff for linkset siuc
dpc => siuc:0x189d
?
; Syntax: links => link-name:digium-connector-no
; The links on the host is 'l1', connected to span/connector #1
links => l1:1
?
; The SCCP global title: translation-type, nature-of-address, numbering-plan, address
;globaltitle => 0x00, 0x04, 0x01, 4546931411
