6.1 Standalone Mobile Interworking Module"Distributed DCE"

Conclusion:

By comparison with PSTN access, the set of functions

comprising:

"TAF + GSM/UMTS transmission subsystem + IWFcan be considered as a DCE distributed throughout the

PLMN. This DCE has a standard set of interchange circuits and

transmission characteristics conforming to ITU

recommendations.

The various applications already developed within thePSTN/ISDN can therefore easily be ported to a GSM

network.

6.1 Standalone Mobile Interworking ModuleManagement commands

The INTMIMcommand also lets you interrogate (display) the characteristics

of a particular SMIM :

The SPC of the SMIM in the localsignalling network of the RCP

The MIWx boards in the SMIM. The MIWx boards are referenced here

by their number in the rack, 1 to 5 from the middle of the subrack going

outwards.

The name of any associated SMIM

The state of the SMIM (in service, out of service or initialising)

It is possible to place an SMIM in or out of service respectively using the

SETMIM: INand SETMIM: OUTcommands.

The INTIMAcommand for interrogating the SMIM alarms indicates the

defective board (the number of the MIWx or the DTR) and in some cases the

cause of the fault.

MSRNis a temporary number in E.164 format provided by the Visited MSC to the Gateway MSC : it will be translated

by the gateway SSP (and maybe by intermediate transit exchanges) in a routing solution to the target MSC.

6.2 MSRN common pool managementHow to do it ?

INTMRNcommand lets you interrogate the MSRNscommon pool declared in the database of an RCP : Itprovides the first MSRN of the database (in national

[recognition]and international [allocation] formats )and the number of MSRNs in the pool.

IWFTYP : Inter Working Function type

CREMRNallows the operator to create a MSRN pool

IWFTYP : Inter Working Function type

ROAMTYP : Roaming type

DIGREC : First MSRN number for recognition

DIGALL : First MSRN number for allocation

LGPOOL : Length of the pool

DELMRNallows the operator to delete a MSRN pool IWFTYP : Inter Working Function type

ROAMTYP : Roaming type
