14.4.2. Global switch configuration 
This is the minimal configuration so that basic features (preemption,
call forwarding, etc..) will work according to MLPP requirements. First
of all you have to enable the feature MLPP:
CHANGE-FEASU:TYPE=A,CM=MLPP; CHANGE-FEASU:TYPE=D,CM=EMOVR&EMRLS;
Assign the service domain for the switch. The first two digits are for network identification
and the last three digits are for the service domain (0-0-0-0-0 is the default value
unless
otherwise specified by the customer).
CHANGE-ZAND:TYPE=MLPP,MAUTO=NO,MCAMP=NO, MTONE=NO,MLPPDISP="P0P1P2P3P4",MLPPDOM=0-0-0-0-0; MDIVAC=YES;
IMPORTANT:
The MDIVAC has to be set for night station even if there is no
attendant console!
CHANGE-ZANDE:TYPE=MLPP,DOMALLOC=NO,DOMCHECK=NO, MCIQTAC=YES,USMUDIV=YES,USMUXFER=YES,FWDPREC=YES, CAMPPREC=YES,PNTTGLE=YES,MCAUSE=YES,CWTPRECT=YES, CONFDSCT=YES;
Assign the access codes for precedence levels.
ADD-WABE:CD=90,DAR=FLASHOV,CHECK=N; ADD-WABE:CD=91,DAR=FLASH,CHECK=N; ADD-WABE:CD=92,DAR=IMMED,CHECK=N; ADD-WABE:CD=93,DAR=PRTY,CHECK=N; ADD-WABE:CD=94,DAR=DSNR,CHECK=N; ADD-WABE:CD=95,DAR=PROT,CHECK=N;
For each subscriber the highest allowed precedence level and the service domain has
to be
configured. The customer must specify the precedence level for each subscriber.
PRECLEVL is the parameter used to set the allowed level. SVCDOM is the service
domain, use 0-0-0-0-0 as default unless otherwise specified by the customer. The first
two
digits are for network identification and the last three digits are for the service
domain.
CHANGE-SDAT:STNO=<station number>, TYPE=DATA1,NNO=1-1-755,SVCDOM=0-0-0-0-0, PRECLEVL=FLASHOV,CLASSSEC=TRADITIO;
Define the protocol elements by copying the protocol definition table.
COPY-PRODE:TYPE=PVCD,PVCDNO=16;
Prevent call forwarding of precedence calls to voice mail (if voice mail is installed)
CHANGE-RICHT:LRTE=<route to voice mail>, NOPRCFWD=YES;
