Configuring Connection with BSC/MSC/PSTN
Configuring TDM Time Slots (1)
Command: ADD ADD TDMIU This command command is used to designate which which VMGW the TID belongs
to as the UMG8900 supports VMGW functions func tions and can allocate TDM resources of one physical physic al device to multiple VMGWs. It could also designate the CMU that manages the TID. An E32/T32 E32/T 32 has 1024 1 024 physic phy sical al time slots at most. Therefo T herefore, re, the th e
end TID minus the start TID must must be less than 1024. The start TID of a TDM interface board (E32/T32/S2L) must be an
integral multiple of 1024.

Configure Local Office Information
Command: SET OFI/ADD OFI
MSOFTX3000 support 16 local office information tables( numbered 0
15).
~
The local office data index added for the first time is "0". SET OFI is used for the first time to add local office data.
Currently, MSOFTX3000 supports multi-SP configuration at the local office, so we could use the command ADD OFI to add SPs to break the number limitation of 16 signaling links.
Configuring Configurin g M3UA Link
Add MTP2 Links:
Command: ADD MTP2LNK.
This command is to configure the link in MTP2 layer. The MTP2 link could transfer the M2UA signaling and bear the MTP3 signaling.
The MTP2 link can be applied to the M2UA or MTP3 layer, to configure an SG based on M2UA, select the MTP2 link type for M2UA; to configure an SG based on M3UA, select the MTP2 link type for MTP3.
Configuring Configurin g MTP Link
Add Destination Point :
Command: ADD N7DSP.
These MTP3 destination destinati on signaling points form the topology of the signaling network where the local office MTP3 signaling points are are located.
Network indicator and local office SPC have been defined when we add local office information.
STP flag is to configure c onfigure whether HLR have ha ve STP function, it is up to network and operator.
HLR is directly connected with MSC, they are adjacent network entity in SS7 signaling network, so this adjacent flag is True.
Configuring Configurin g MTP Link
Add MTP Link Set:
Command: ADD N7LKS.
An MTP3 link link set set is a group group of signaling signaling links between between two adjacent signaling points
Adjacent Adjacent DSP index index is a index index of associated associated DPC to define define the destination of the link set. This index must be set in the former table.
Configuring Configurin g MTP Link
Add MTP Route:
Command: ADD N7RT.
An MTP3 route route is the path throug through h which signaling signaling messages messages are transmitted between two signaling points.
This command defines routes used by a link set.
The link set and DPC must be added in the two former tables.
Configuring Configurin g MTP Link
Add MTP Link:
Command: ADD N7LNK.
Module number is the module module number of WCSU board (or SGU board).
Circuit number is the time slot sl ot number of E1 used by the link, usually use 16th time slot in E1 as the signaling sign aling link, need to consult with HLR configuration.
Link Set Index indicates that that which link set the link is belong to.
SLC is a appointed value, it is a interface parameter, parameter, need to c onsult with with HLR configuration.
Choose 64k link, if need to use one E1 time slot as the signaling link.
Configuring Configurin g M3UA Link
Add IP Address:
Command: ADD IPADDR.
This command is used to configure the IP address of a specified interface on a specified board. In this chapter it is used to configure the IP address of SPF board.
It could be used to configure master, slave, and test IP addresses.
To configure multiple addresses for an IP interface, configure the master IP address first before a slave IP address. otherwise, configuring a slave IP address will fail.
Configuring Configurin g M3UA Link
Add M3UA Local Entities:
Command: ADD M3LE.
An M3UA M3UA local local entity correspon corresponds ds to an origin originating ating signaling signaling point point code (OPC) that is identified by network ID (NI) and OPC.
Local entity type specifies the application mode of the UMG8900 in the M3UA link. For the two peer devices, if the entity type is Applicatio Application n Server (AS) (AS) for one one device, device, the entity type is is SG for the the other.
Usually the entity type is set to SG for the UMG8900 and AS for MGC.
Configuring Configurin g M3UA Link
Add M3UA Destination Entities: Entities:
Command: ADD M3DE.
An M3UA M3UA destination destination entity defines defines a destination destination signaling signaling point point and is identified by NI and DPC.
Network Mode is valid only when the destination entity type is AS. It specifies whether the peer AS engrosses or shares a signaling point code with others.
Configuring Configurin g M3UA Link
Add M3UA Link Sets:
Command: ADD M3LKS.
A group group of M3UA M3UA links between between the local entity and and adjacen adjacentt destination entity constitute a M3UA link set.
An M3UA M3UA link set describe describes s the static features features of all the M3UA M3UA links from the local entity to an M3UA adjacent destination entity.
Configuring Configurin g M3UA Link
Add M3UA Routes:
Command: ADD M3RT.
M3UA route is the path from the local entity to the destination entity is called.
There can be multiple routes to a M3UA destination entity, but the routes to the same M3UA destination entity must use different M3UA link sets.
Configuring Configurin g M3UA Link
Add M3UA Signaling Signaling Links:
Command: ADD M3LNK.
The link set up between the SGP and the ASP through SCTP is called M3UA link.
Each end of an M3UA link can be either the SGP or the ASP (IPSP is not applied in the UMG8900).
First IP address is a mandatory parameter, and if second address is also specified, this configuration shall support the dual homing function.

Data Configuration Step (MGW side)
Between the UMG8900 and and MSC M SC Server common comm on channel signaling can be transferred through semi-permanent connections between TDM time slots. When a semi-perma semi -permanent nent connection is established between the TDM time slots s lots that bear the signaling, the two TDM time slots are always in the connected state. The SS7 signaling s ignaling is transparently transferred through this connection.

The UMG8900 can serve as an MGW in the t he core network, where it can interwork with other MGWs over over IP, TDM or ATM bearers.

ADD IP IPADDR ADD GWADDR GWADDR
Configuring IP Gateway
Add IP Gateway Address:
Command: ADD GWADDR
The purpose of configuring gateway address is to forward IP packets carrying services to the desired gateway. As an IP packet is unaware of its destination when being configured, you are unable to configure forward information of the IP packet with the ADD ROUTE ROUTE command command,, which which requires requires destination destination address. address.
An IP interface interface can be configured configured with two gateway gateway addresse addresses s at most.
Configuring IP Bearer Capability
Add IP resources for VMGW:
Command: ADD VMGWIP
For the UMG8900 supports VMGW functions, we use this command to allocate the IP bearer capability for each VMGW. IP bearer capability is the number of the combinations IP address + “
UDP port . ”
The UDP ports of an IP address can be shared by multiple VMGWs or be exclusively occupied by one VMGW; on the other hand, one VMGW can occupy UDP port resources of multiple IP addresses.
