3.12.3. Generation (Example) 
The digital MFC-R2 line signaling version described by ITU-T Q.400-Q490
can be configured in OpenScape Access/Branch with the OpenScape Access
PRI module.
The DIUT board must be configured in E1/CAS functionality (FCTID=2),
for example
ADD-BCSU:MTYPE=DIU,LTG=1,LTU=19,SLOT=3,PARTNO="Q2335-X",LWVAR=0,FCTID=2,HWYBDL=A,ALARMNO=0,MACADDR=00-1A-E8-32-60-5E,TDMLAW=0;
Additionally, a vSIUX2 must be configured. Configuration of vSIUX2
is the same as for standard SIUX2 boards. MFC-R2 functionality is selected
by configuring the Q2341-X function ID3. Within the ID3 function, vSIUX
only provides a MFC subset of R2, i.e. MFC-R2 forward and backward functionality
(other MFC variants such as R1, SOCOTEL or MFP are not supported).
Depending on the configuration, you can set up a maximum of 8 MFC-R2
signal receivers and MFC signal transmitters on this. These always operate
in pairs and the configuration is also always in pairs, for example
ADD-BCSU:MTYPE=SIUP,LTG=1,LTU=19,SLOT=5,PARTNO="Q2341-X", MFCTYPE=R2B&R2B&R2F&R2F&R2F&R2F&R2F&R2F,LWVAR=0,FCTID=3;
is the configuration for 2 backward signal transmitters (which includes
2 forward receivers) and 6 forward transmitters (which includes 6 backward
receivers).
Other SIUX functionality (e.g. DTMF, ANI,
) is not implemented in
vSIUX2. If it is configured by AMO, the board remains unavailable.
IMPORTANT:
Initialization can be performed in an active system
but will only be activated when the shelf has been reloaded (AMO USSU).
There is no indication from AMO BCSU that a restart has to be performed.
Initialization of MFC signals
A default initialization of MFC signals (frequency and attenuation)
is performed in vSIUX2 code. The frequency of all signals is defined
according to Q.441 of ITU-T Q.400-Q490, attenuation is set to -8dBm0.
It is possible for national applications to provide special signal
definitions by means of special initialization files. By default there
are three different files on the system's hard disk.
- APSP/LTG/LG25/PZJSMFD0 is the initialization file for default signals, A-law
- APSP/LTG/LG25/PZJSMFD1 is the initialization file for default signals, µ-law
- APSP/LTG/LG25/PZJSMFD2 is the initialization file for signals for Brazil (A-law, -13dmB0)
The initialization file can be selected by AMO ZAND, for example
-
CHANGE-ZAND:TYPE=SIUXPER,LEVMFC=2;for BrazilInitialization file 0 is selected by default. In addition to the signal description, the file also indicates which HWY/TSL is to be used for which line on SIUX.
