Default
MFC routes were given a CAC prompt on which was configured the CAC
value of incoming route when tandeming to CIS. This data has no more
utility on incoming MFC route as a CAC conversion table is configured
against prompt CAC_CONV. Thus, CAC prompt is removed from MFC
incoming routes. On upgrade, former CAC prompt value is moved into a
CAC conversion table, and this table is assigned to the route.
In the gateway side CIS to R2MFC, the purpose of this mapping is to
convert the 10 CIS CAC meanings into R2MFC CAC value. For this, a
conversion table is defined.
Prior to upgrading, the CAC sent was defined in the R2MFC table (LD 94).
In this R2MFC table, it is the same value for all non-tie incoming trunks. In
LD 15, for CAC conversion table, the same range (1-10) and default value
(6) than in LD 94 are used. The value 0 is also allowed, it means that the
value defined in R2MFC table for incoming non-Tie trunk has to be used.
CAC conversion tables must be defined by the craftsperson in LD 15. Up
to 32 tables can be configured. Then a configured conversion table entry
can be assigned on each incoming DTI2 CIS route. For this, new prompt
CAC_CONV is added to the CIS incoming route configuration. If no CAC
conversion table is configured on the CIS route, the default table entry
number 0 will apply on CIS incoming routes.
Default table entry is number 0 and is configurable. During upgrades, this
table is defined in memory as shown in
CIS incoming DTI2 route" (page
to 0, the R2MFC table is used until default table number 0 is configured.
