10.56.4. TFZ Signaling 
TFZ signaling has been developed for the digital interface between
OpenScape 4000 and the special telephone networks of the traffic enterprises.
Loadware variant 5
The loadware with TFZ signaling for the DIUC boards must be available
on the OpenScape 4000 system hard disk:
:PDS:APSP/LTG/LG57/PZFDCAS5 (for DIUC Q2185)
- You can configure the DIUC board with loadware variant 5 as follows:
DIUC64:
ADD-BCSU:TYPE=DIU,LTG=gg,LTU=uu,SLOT=bbb, PARTNO="Q2185-X",LWVAR=5;
- The loadware variant can be subsequently assigned as follows:
DIUC64 (Q2185):
CHA-ZAND:TYPE=LOADWARE,LWTYPE=DCAS,LWVAR=5; (for DIUC Q2185)
IMPORTANT:
To load the LWVAR, the board with the AMO BSSU must be switched off and on again.
Device TSTFZ
The following example shows the configuration of TFZ tie trunk circuits
with suffix-dialing.
- You can configure the class of trunk for TFZ tie trunk circuits as follows:
ADD-COT:COTNO=x,PAR=AND&USD;
- You can configure the trunk parameter circuits for TFZ tie trunk circuits as follows:
ADD-COP:COPNO=x,PAR=SDL&BR64&NO1A&IDP3&MSG& RLSA&RLSB&LSUP&TIE;
- You can configure the TFZ trunk group for tie trunk traffic (for example
30 circuits) as follows:
ADD-BUEND:TGRP=x,NAME="TFZ-TIE",NO=30;
- You can configure 30 tie trunk circuits with TFZ signaling as follows:
ADD-TACSU:NO=30,PEN=gg-uu-bbb-1,COTNO=x, COPNO=x,TGRP=x,DEVTYPE=AS,DEV=QSTFZ;
PTIME init block for device TSTFZ
The initialization data for the device TSTFZ are saved on the hard
disk in init block 40 (see AMO PTIME). The data are loaded automatically
from the AMO TACSU. To change a fixed default value (for example two-way,
incoming), the following steps must be taken:
- Load init timer block 40 from the hard disk into the DB (into TBLK 11,
for example) with:
COPY-PTIME:INIBLOCK=40,TBLK=11;
- You can change the value for parameter 3 with:
CHA-PTIME:TYPE=REST,TBLK=11,BTYPE=PARA,P3=2;
- You can assign the new timer block 11 to all trunk groups as follows:
CHA-TACSU:PEN=gg-uu-bbb-ss,DEVTYPE=AS, DEV=TSTFZ,CIRCIDX=11;
IMPORTANT:
To load the new parameters, all relevant circuits with the AMO DSSU must be switched off and on again. Alternatively, you can also selectively assign the modified timer block when configuring the circuits.
