CIRCUIT CARD EXPLANATIONS
When using an IPTRK circuit card for FCCS Networking via IP [F-36] (Point-to-Multipoint Connection),
connect an Ethernet cable from the IPCON connector to the router. Next, connect another Ethernet cable
from FCON connector to LANI card (CPR, PCI slot 00/03) via HUB. The following figure is an example
when connecting the IPTRK circuit card to the LANI of CPU0, PCI slot 0. When 100BASE-TX Ethernet
cable is connected to IPCON/FCON connector,...

2.1 Required Hardware
This feature is available using the following hardware. As shown, both signal and speech paths can be
provided by connection of IPTRK circuit cards between the nodes.
Figure 3-2   Example of Required Hardware for CCIS Networking via IP [C-163]
Note:
One IPTRK circuit card assigned as CCH by the ACSC command is assumed as the D-channel controlling
card, used as the speech circuit as well. The IPTRK circuit card can control...

2.2 Required Hardware (Point-to-Multipoint Connection)
This feature (allowing IPTRK circuit cards for both speech and CCIS signal channels) is available by using
the following hardware. Once this feature is set, each IPTRK circuit card can make a Point-to-Multipoint
connection with IPTRK circuit cards of multiple nodes.
Note:One IPTRK circuit card assigned as CCH by the ACSC command is assumed as the D-channel controlling
card, used as the...

2.3 Service Conditions
1. To send/receive speech and CCIS signals, each node will use an IPTRK circuit card. At this time, the
IPTRK circuit cards in the self-node and each of its connected node can be in either 1-to-1 ratio, or in 1-
to-n (n=2 or more) relations. This is referred to as Point-to-Multipoint connection.
2. A maximum number of two IPTRK circuit cards per UNIT are allowed. Accordingly, a total of 16 IPTRK
circuit cards can be...

6. Tandem Path through function is not provided.
7. This feature supports QoS (Quality of Service) function.
8. When a system message indicates “TCP link failure” due to data congestion on the router or IP network,
a call cannot be made via an IPTRK circuit card. When a call is attempted despite this, the caller hears
busy tone.
9. When a system message related to “TCP link failure” is created during call origination or speech, that
call’s...
