2.2 Conditions for Network Establishment (NEAX2000 IVS
2
to NEAX2400 IMX Connection)
Conditions for connecting the NEAX2000 IVS
2
to NEAX2400 IMX are described below.
1. All IVS
2
systems must be directly connected to an IMX. See Figure 8-2.
Figure 8-2 NEAX2000 IVS
2
to NEAX2400 IMX Connection
2. The number of logical routes available (899) in the FCCS network is reduced by one for every route
provide in the NEAX2000 IVS
2
when connected via Enhanced CCIS.
Note:
The above is a condition of data assignment in the NEAX2400 IMX system. The NEAX2000 IVS
2
system
accommodates up to 255 nodes (including NEAX2400 IMX and NEAX2000 IVS
2
systems). The number of
point codes assignable in the NEAX2000 IVS
2
system is a maximum of 255, including Enhanced CCIS net-
works.
3. When directly connecting a NEAX2000 IVS
2
to a NEAX2400 IMX, one signal channel may support
multiple voice routes. However, when the Enhanced CCIS function is provided with EVENT BASED-
CCIS, a signal route must be provided per voice route.
