11. This feature does not support Broad Band Services H0/H1. Therefore, when assigning the IPTRK circuit
card routes by the ARTD command, enter BOB = 0.
12. This feature can use link re-connection function. Service conditions are the same as those for the normal
CCIS network.
13. PAD can be provided for RECEIVE control only.
14. On a conference call via IPTRK, Echo Canceller cannot be activated when using certain kinds of telephone
sets (generally analog telephones).
15. During IPTRK circuit card-related tandem connection, speech quality can become poor, or dual
connection failure may occur. DTMF and FAX relay cannot be used.
2.4 Data Programming
To activate this service via the Intranet, perform the data programming as follows:
Note:When office data is assigned/modified, be sure to initialize the IPTRK circuit card (by flipping its MB key
OFF 
→ ON → OFF).
STEP 1:Assignment of basic CCIS network data
Referring to the NEAX2400 IPX No. 7 CCIS System Manual, assign all the basic data (such as ASYD,
ARTD, ATRK, ADPC, ACSC, ACIC1, ACIC2, MBTK, etc.), necessary for the establishment of a
CCIS Tie line.
When assigning this data, consider the following:
Enter IPTRK = 1 for B-channel route on the ARTI command.
For the port assignment (B-ch) of the IPTRK circuit card, see Figure 3-3.

Note 2:This example represents the port allocation when sub board PZ-8VCTB is mounted.
Note 3:Be sure to assign a B-channel in the first time slot of the controlling IPTRK circuit card.
CCIS signal controlling channel is determined in accordance with the CIC numbers of speech
channel. To provide multiple interfaces for a single Point Code (activating CCIS and CCIS network
via IP together within one network), CIC numbers and CIC Group (CICG) must be assigned on the
same interface.

3. FCCS NETWORKING VIA IP [F-36]
This feature allows the system to exchange both speech and FCCS signals via the Intranet. It is not necessary to
use an FCH circuit card. To establish/release a call, the following connection patterns can be selected:
For both speech and FCCS signal channels, an IPTRK circuit card is used. At this time, the IPTRK circuit cards
in the self-node and each of its connected node(s) must be in 1-to-1 ratio. See Section 2.4 Data Programming.
When utilizing Point-to-Multipoint Connection for both speech and FCCS signal channels, an IPTRK circuit
card is used. At this time, the IPTRK circuit card, accommodated in the self-node, can be connected to multiple
destinations (IPTRK circuit cards of multiple nodes). See Section 2.4 Data Programming.

3.3 Service Conditions
1. To send/receive voice information, each node will use an IPTRK circuit card. At this time, the IPTRK
circuit cards in the self-node and its connected node(s) can be either in 1-to-1 ratio, respectively, or in 1-
to-n (n=2 or more) relations (referred to as Point-to-Multipoint connection). 
2. Be sure to use a router for connections between IP network and IPTRK circuit card.
3. A maximum of two IPTRK circuit cards per UNIT are allowed. Accordingly, a total of 16 IPTRK circuit
cards can be accommodated per IMG.
4. Only voice and FAX (G3) information can be sent/received via IPTRK circuit card.
5. A call cannot be established/routed across multiple IP networks. See the following figure.
6. When multiple IPTRK circuit cards are used for node-to-node connection and all the lines on an IPTRK
are busy, alternate routes are available (see the figure below). However, if a router cannot be used, all the
related IPTRK routes are made unavailable.

7. For Point-to-Multipoint connection, one IPTRK circuit card (assigned as FCCS signal controlling card by
the AFCH command), can control the B-channels of the same card, and also a maximum of 15 other
IPTRK circuit cards. It is not necessary to assign the trunk data for a time slot as a controlling channel.See
the following figure.
Note 1:The IPTRK circuit card can be accommodated in the shaded slots (a maximum of two cards per UNIT).
HW indicates Highway Block.
Note 2:Be sure to assign a B-channel in the first time slot of the controlling IPTRK circuit card.
8. During IPTRK circuit card-related tandem connection, speech quality can become poor, or dual
connection failure may occur. DTMF and FAX relay cannot be used.
9. Any service that is not available for the FCCS network, is not available utilizing this service.
10. This feature supports QoS (Quality of Service) function.
11. 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.
12. When a system message, related to “TCP link failure”, is created during call origination or speech, that
call’s speech channel is automatically restored via patrol function.
