Channel Based Operation
- Kelli Higdon
Monitoring Signaling Links
From the FreeSWITCH/SMG cli run: "ftdm ss7 show status mtp3 <mtp3 name>"
# ftdm ss7 show status mtp3 mtp3-1
link1|span=1|chan=1|sap=1|state=Aligned|l_blk=N|r_blk=N|l_inhbt=N|r_inhbt=N
link1 => link name
span => TDMV_SPAN value
chan => physical channel number
sap => ftmod_sangoma_ss7 internal id for this sig link
state => state of link;
OUT OF ALIGNMENT => link is not active
CONNECTING => MTP is attempting to align the link
ALIGNED => MTP has aligned the link
l_blk => link is in local processor outage (lpo)
r_blk => link is in remote local processor outage (lpo)
l_inhbt => link is inhibited locally
r_inhbt => link is inhibited remotely
From the FreeSWITCH/SMG cli run: "ftdm ss7 show status mtp2 <mtp2 name>"
# ftdm ss7 show status mtp2 mtp2-1
mtp2-1|span=1|chan=16|sap=1|state=bnd-enabled|outsFrm=0|drpdFrm=0|lclStatus=N|rmtStatus=N|fsn=78|bsn=81

Monitoring Signaling Link Sets
From the FreeSWITCH/SMG cli run: "ftdm ss7 show status linkset <linkset name>"
# ftdm ss7 show status linkset LS1
LS1|state=InActive|nmbActLnk=1
state => linkset is either active or inactive
nmbActLnk => number of active links within this linkset

Monitoring Voice CICs
From the FreeSWITCH/SMG cli: "ftdm ss7 show status span X chan Y"
# ftdm ss7 show status span 1 chan 4
span= 1|chan= 4|cic= 4|sig_status=UP|state=DOWN|l_mn=N|r_mn=N|l_hw=N|r_hw=N|l_mngmt=N|l_ucic=N|flags=0x000000
span => TDMV_SPAN value
chan => physical time slot on the span
cic => the assigned cic value
sig_status => FreeTDM signaling module status; DOWN ( sig stack has flagged this channel as unavailable), UP ( sig stack has flagged channel as available)
state => FreeTDM channel state; DOWN, RINGING, DIALING, PROGRESS, PROGRESS_MEDIA, UP, TERMINATING, HANGUP, HANGUP_COMPLETE, CANCEL, RESTART and SUSPENDED
l_mn => local maintenance block
r_mn => remote maintenance block
l_hw => local hardware block
r_hw => remote hardware block
l_mngmt => local management block
l_ucic => Unequipped CIC message recieved
flags => ftmod_sangoma_ss7 internal flags
Blocking/Unblocking Signaling Links
To block/unblock the link:
From the FreeSWITCH/SMG cli: "ftdm ss7 deactivate link <linkname>" or or "ftdm ss7 activate link <linkname>".
# ftdm ss7 deactivate link link3
name=link3|span=3|chan=16|sap=3|state=Failed|l_blk=N|r_blk=N|l_inhbt=N|r_inhbt=N
# ftdm ss7 activate link link3
name=link3|span=3|chan=16|sap=3|state=Connecting|l_blk=N|r_blk=N|l_inhbt=N|r_inhbt=N
Blocking/Unblocking Voice CICs
There are 2 types of blocks that user can apply: single circuit block/unblock (blo/ubl) or group block (cgb/cgu)
From the FreeSWITCH/SMG cli: "ftdm ss7 blo span X chan y" or "ftdm ss7 ubl span X chan Y"
# ftdm ss7 blo span 1 chan 4
span= 1|chan= 4|cic= 4|l_mn=Y|r_mn=N|l_hw=N|r_hw=N|l_mngmt=N|l_ucic=N|
# ftdm ss7 ubl span 1 chan 4
span= 1|chan= 4|cic= 4|l_mn=N|r_mn=N|l_hw=N|r_hw=N|l_mngmt=N|l_ucic=N|
From the FreeSWITCH/SMG cli: "ftdm ss7 cgb span X chan Y range Z" or "ftdm ss7 cgu span X chan Y range Z"
# ftdm ss7 cgb span 1 chan 3 range 2
span= 1|chan= 3|cic= 3|l_mn=Y|r_mn=N|l_hw=N|r_hw=N|l_mngmt=N|l_ucic=N|
span= 1|chan= 4|cic= 4|l_mn=Y|r_mn=N|l_hw=N|r_hw=N|l_mngmt=N|l_ucic=N|
# ftdm ss7 cgu span 1 chan 3 range 2
span= 1|chan= 3|cic= 3|l_mn=N|r_mn=N|l_hw=N|r_hw=N|l_mngmt=N|l_ucic=N|
span= 1|chan= 4|cic= 4|l_mn=N|r_mn=N|l_hw=N|r_hw=N|l_mngmt=N|l_ucic=N|
Resetting Voice CICs
There are 2 types of resets that users can apply to CICs: circuit reset (rsc) and circuit group reset (grs)
From the FreeSWITCH/SMG cli: "ftdm ss7 rsc span X chan Y"
# ftdm ss7 rsc span 1 chan 4"
span= 1|chan= 4|cic= 4|sig_status=UP|state=RESTART|l_mn=N|r_mn=N|l_hw=N|r_hw=N|l_mngmt=N|l_ucic=N|flags=0x000000
From the FreeSWITCH/SMG cli: "ftdm ss7 grs span X chan Y range Z"
# ftdm ss7 grs span 1 chan 4 range 2"
span= 1|chan= 4|cic= 4|sig_status=UP|state=RESTART|l_mn=N|r_mn=N|l_hw=N|r_hw=N|l_mngmt=N|l_ucic=N|flags=0x000000
span= 1|chan= 5|cic= 5|sig_status=UP|state=RESTART|l_mn=N|r_mn=N|l_hw=N|r_hw=N|l_mngmt=N|l_ucic=N|flags=0x000000
