Networking with NEAX2400 IPX and NEAX2000 IVS
2
General Description
The following explains connectivity issues between a NEAX2400 IPX and a NEAX2000 IVS
2
. An FCCS Group
consists of a network where multiple NEAX2400 IPXs are connected via FCCS link.
Note:
NEAX2400 IPX - NEAX2000 IVS
2
connection is available only if the NEAX2000 IVS
2
is the satellite office
(requires NEAX2000 IVS
2
Series 2000 or later software).
Service Conditions
Network Configuration
1. The following table shows the summary of network configurations:
Note:
For details, refer to the following services:
Maintenance - Centralized System Management Report - CCIS [C-57]
Billing - Centralized Billing - CCIS [C-55]
MCI - Message Center Interface - CCIS [M-67]
2. There are two connection types for the network:
a.) NEAX2000 IVS
2
- NEAX2400 IPX connection
b.) NEAX2400 IPX - NEAX2400 IPX connection
Network Establishment
• NEAX2000 IVS
2
- NEAX2400 IPX
1. Additional NEAX2000 IVS
2
s cannot be connected to a NEAX2000 IVS
2
that has already been connected
with NEAX2400 IPX. Only one SPAN is allowed for NEAX2400 IPX - NEAX2000 IVS
2
connection.
2. The maximum number of routes and nodes for the NEAX2000 IVS
2
are given by subtracting the number
of routes (LGRT) used for the NEAX2400 IPX from 899 (maximum number of routes in an FCCS group).
Note: This condition is applied to the NEAX2400 IPX side. The NEAX2000 IVS
2
system may accommodate up to
255 nodes (including NEAX2400 IPX), because the maximum number of Point Codes (PCs) assigned at
NEAX2000 IVS
2
system is 255, including the nodes in the network.
3. When the signal route is deleted, the voice route is used per route, but the signal route can be shared with
multiple routes. However, when the network is established using EVENT BASED-CCIS, the signal route
must be used per route.
• NEAX2400 IPX - NEAX2400 IPX
1. The maximum number of NIDs per FCCS group is 253.
2. The maximum number of routes assigned in each FCCS group is 899.
3. An NCN and NDM exist in each FCCS group.
