2.2Conditions for Network Establishment (NEAX2000 IVS2 to NEAX2400 IMX Connection)

Conditions for connecting the NEAX2000 IVS2 to NEAX2400 IMX are described below. 1. All IVS2 systems must be directly connected to an IMX. See Figure 8-2.

NEAX2000 IVS2 (B) cannot be added to NEAX2000 IVS2 (A) which is already connected with

NEAX2400 IMX.

2.The number of logical routes available (899) in the FCCS network is reduced by one for every route provide in the NEAX2000 IVS2 when connected via Enhanced CCIS.

Note: The above is a condition of data assignment in the NEAX2400 IMX system. The NEAX2000 IVS2 system accommodates up to 255 nodes (including NEAX2400 IMX and NEAX2000 IVS2 systems). The number of point codes assignable in the NEAX2000 IVS2 system is a maximum of 255, including Enhanced CCIS net- works.

3.When directly connecting a NEAX2000 IVS2 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.
