# This file is parsed by the Zaptel Configurator, ztcfg
#

# It must be in the module loading order

# Span 1: TE4/0/1 “T4XXP (PCI) Card 0 Span 1″ (MASTER)
span=1,1,0,ccs,hdb3,crc4
# termtype: te
bchan=1-15,17-31
dchan=16

# Span 2: TE4/0/2 “T4XXP (PCI) Card 0 Span 2″
span=2,2,0,ccs,hdb3,crc4
# termtype: te
bchan=32-46,48-62
dchan=47

# Span 3: TE4/0/3 “T4XXP (PCI) Card 0 Span 3″
span=3,3,0,ccs,hdb3,crc4
# termtype: te
bchan=63-77,79-93
dchan=78

# Span 4: TE4/0/4 “T4XXP (PCI) Card 0 Span 4″
span=4,4,0,ccs,hdb3,crc4

6) edit ss7.conf like this:
===========================
[linkset-ls1]
enabled => yes
enable_st => yes
use_connect => no
hunting_policy => even_mru
context => ss7_call
language => en
subservice => auto
variant => CHINA ; 支持中国ss7 号信令
[link-l1]
linkset => ls1
channels => 1-15,17-31
schannel => 16
firstcic => 1
enabled => yes

echocancel => no
echocan_train => 350
echocan_taps => 128

[link-l2]
linkset => ls1
channels => 1-31
schannel =>
firstcic => 33
enabled => yes

[link-l3]
linkset => ls1
channels => 1-31
schannel =>
firstcic => 65
enabled => yes

[link-l4]
linkset => ls1
channels => 1-31
schannel =>
firstcic => 97
enabled => yes

[host-openvox]
enabled => yes
opc => 0×222222
dpc => ls1:0×298922
links => l1:1,l2:2,l3:3,l4:4
===========================
7) edit extensions.conf：
==========================
[ss7_call]
exten => 100,1,Dial(ss7/outgoing number)
exten => 100,2,Hangup
==========================
make sure ss7 is up:
==========================
CLI> ss7 link status
linkset ls1, link l1, schannel 16, sls 0, INSERVICE, rx: 5, tx: 1/3, sentseq/lastack: 4/4, total    199328,    199424
CLI> ss7 status
