C-167 Centralized Maintenance - CCIS
General Description
This FCCS service allows all nodes (NEAX2400 IPX systems) in the multiple FCCS groups (networks where
multiple NEAX2400 IPXs are connected via FCCS link) and NEAX2000 IVS
2
systems, connected via CCIS link,
to be maintained from a single MAT. The MAT used for this feature is called Centralized MAT.
Note: Requires NEAX2000 IVS
2
Series 2000 or later software.
Operating Procedure
Refer to the NEAX2400 IPX CCIS No.7 System Manual.
Service Conditions
NEAX2000 IVS
2
1. The data transmission speed between a NEAX2000 IVS
2
and a NEAX2400 IPX is 64 kbps maximum.
2. Internal MAT software for NEAX2400 IPX and NEAX2000 IVS
2
are installed in a MAT and start up the
software at the node to be logged in to.
3. See the manual describing NEAX2400 IPX for the method of checking the log-in user.
NEAX2400 IPX
1. All the systems in the network can be maintained by a single MAT (Centralized MAT).
2. The existing system (not NEAX2400 IPX) cannot be maintained via the Centralized MAT.
3. Time required for transmitting the 1 mbyte data (1 block of Data Memory) is 2 hours at 64 kbps data speed/
1 hour at 128 kbps data speed/15 minutes at 512 kbps data speed.
4. The number of MATs to be installed may vary depending on the customer specification (one or two MATs
can be used to centralize the MAT operation, and three or more MATs can be used to separate the MAT
operation).
5. By user ID and password written in the NDM of each FCCS group, the log-in user is checked when
logging in to the NEAX2400 IPX. This data is decided by the AUIDN command.
6. When on e of the conditions below are applied, the MAT is logged in to the node designated by the FPC,
but within the FCCS group where the MAT is installed, regardless of the designated FUG number (FCCS
group number) data.
a.) When no data is assigned to the SELF_FUG (FUG number in the self-FUG) in the AFUGN
command.
b.) When the FUG requested by the MAT is “0”.
c.) When the FUG requested by the MAT is the FUG number of the self-FUG.
7. The traffic information of the NEAX2000 IVS
2
may be collected from the Centralized MAT by logging
into the NEAX2000 IVS
2
node, and using the traffic information collecting command dedicated to the
NEAX2000 IVS
2
.
8. The function to collect traffic information of the NEAX2400 IPX is activated by logging into the NCN
(Network Center Node) of each FCCS group.
