5.6.9.10. Class of Service Configuration 
The Class of Service interworking implemented by the Enhanced CDG
feature converts between the following values in OpenScape 4000 and Realitis
DX;
|
OpenScape 4000
|
DPNSS
|
Note
|
|
LCOS
|
RRC
|
In OpenScape 4000 LCOS is 2 parameters
LCOSV
for Voice calls
LCOSD for Data calls
This is known as TAC
in Realitis DX
|
|
ITR
|
CBG
|
where the originator or terminator is an extension
terminal
(ITR group is also know as VBZGR in OpenScape 4000)
|
|
ITR
|
Trunk Group
|
where the originator or terminator is a trunk
|
The values used by the OpenScape 4000 and Realitis DX for these parameters
do not have the same range, and to facilitate integration of OpenScape
4000 and Realitis DX switches in mixed networks the Enhanced CDG feature
provides mapping tables for these parameters to convert between the OpenScape
4000 and DPNSS1 values.
Class of Service Parameters:
LCOSMAP: this parameter is used to enable or disable the mapping
of all the parameters in the table following. The default value is 'enabled'
and is configured using AMO LWPAR:
To enable Class of Service Mapping
CHA-LWPAR:TYPE=CDG,BLNO=<number>,CDGTYPE=CONF,LCOSMAP=Y
To disable Class of Service Mapping
CHA-LWPAR:TYPE=CDG,BLNO=<number>,CDGTYPE=CONF,LCOSMAP=N
LCOSVRRG and LCOSDRRG Tables: These tables convert
between the LCOSV and LCOSD in OpenScape 4000 and the RRC (TAC) value
in DPNSS1. There are separate tables for LCOSV and LCOSD and the table
format for each is shown in Table 4.
Each table is Indexed using the OpenScape 4000 LCOS value. The table
is setup with default values with the DPNSS1 RRC having the same value
as the OpenScape 4000 LCOS - this is shown in :Table 4
(note that the OpenScape 4000 LCOS value sent out on CorNet-NQ has the
value 1 less than the value entered in the AMO).

The table can be configured using AMO LWPAR:
To change a single value in the LCOSVRRG table:
CHA- LWPAR:TYPE=CDG,BLNO=<number>,CDGTYPE=MAPPING,TBL=LCOSVRRG,LCOS=1 ,RRG=32;
To change many values in the LCOSVRRG table:
CHA- LWPAR:TYPE=CDG,BLNO=<number>,CDGTYPE=MAPPING,TBL=LCOSVRRG,LCOS=1 &2&3&4,RRG=32&33&34&35;
To change a single value in the LCOSDRRG table:
CHA- LWPAR:TYPE=CDG,BLNO=<number>,CDGTYPE=MAPPING,TBL=LCOSDRRG,LCOS=1 ,RRG=32;
To change many values in the LCOSDRRG table:
CHA- LWPAR:TYPE=CDG,BLNO=<number>,CDGTYPE=MAPPING,TBL=LCOSDRRG,LCOS=1 &2&3&4,RRG=32&33&34&35;
To set the LCOSVRRG table back to its default settings:
CHA-LWPAR:TYPE=CDG,BLNO=<number>,CDGTYPE=MAPPING,TBL=LCOSVRRG;
To set the LCOSDRRG table back to its default settings:
CHA-LWPAR:TYPE=CDG,BLNO=<number>,CDGTYPE=MAPPING,TBL=LCOSDRRG;
TRGCBG Table: This table converts between the OpenScape
4000 ITR (VBZ) value and the Realitis DX CBG (Call Barring Group) value
when the originator or destination of a call is a terminal on the PBX.
The format of the table is shown in Table 5.
The table is Indexed using the OpenScape 4000 ITR value. The table is
setup with default values with the DPNSS1 CBG having the same value as
the OpenScape 4000 ITR - this is shown in Table 5.

The table can be configured using AMO LWPAR:
To change a single value in the TRGCBG table:
CHA- LWPAR:TYPE=CDG,BLNO=<number>,CDGTYPE=MAPPING,TBL=TRGCBG,TRG=1,CB G=32;
To change many values in the TRGCBG table:
CHA- LWPAR:TYPE=CDG,BLNO=<number>,CDGTYPE=MAPPING,TBL=TRGCBG,TRG=1&2& 3&4,CBG=32&33&34&35;
To set the TRGCBG table back to its default settings:
CHA-LWPAR:TYPE=CDG,BLNO=<number>,CDGTYPE=MAPPING,TBL=TRGCBG;
DXTGITR Table: This table converts between the
OpenScape 4000 ITR (VBZ) value and the Realitis DX Trunk Group Number
( in the Call Barring Group of the DPNSS1 COS) value when the originator
or destination of a call is a trunk circuit. This is used for Trunk-to-trunk
barring within a mixed OpenScape 4000, Realitis DX network.
The format of the table is shown in below. The table has 32 entries.
The table is initially empty.
Entries are added to the table to map Trunk Groups values in Realitis
DX into Trunk Group values in OpenScape 4000 and vice versa.
The range of the OpenScape 4000 ITR value ( 0 to 15) is much smaller
than the Realitis DX Trunk Group values (0 to 200). This can result in
many Realitis DX Trunk Group values mapping onto a single OpenScape 4000
ITR value. This situation is shown in the following table. For the direction
Realitis to OpenScape 4000 the PBXXX converts the values as configured
in the table, searching using the DXTG value. For the direction OpenScape
4000 to Realitis DX the one of the DXTG values must be chosen from the
list ( e.g. in the table shown, OpenScape 4000 ITR value =0, this could
be mapped to DXTG values of 12 or 254 or 127 or 199. The parameter PRIME
is then used by PBXXX to choose which mapping to use; in the example
the OpenScape 4000 ITR value = 0 will be mapped into Realitis DX Trunk
Group value 127.
The parameter PRIME must be configured for one of the mappings where
there are many DX Trunk Group values for the same OpenScape 4000 ITR
value.
