FCCS Networking via IP F-36
F-36 FCCS Networking via IP
         (Series 7400 software feature)
General Description
This feature allows the system to exchange both speech and FCCS signals over Internet/Intranet. To establish/
release a call, the following two connection patterns can be selected:
 IPTRK Point-to-Point Connection: For both speech and FCCS signal channels, an IPTRK circuit card
is used. At this time, the IPTRK cards in the self-node and each of
its connected node(s) must be in 1-to-1 ratio.
 IPTRK Point-to-Multipoint Connection: For both speech and FCCS signal channels, an IPTRK circuit card
is used. At this time, the IPTRK card, accommodated in the self-
node, can be connected to multiple destinations (i.e. IPTRK cards
of multiple nodes).
Point-to-Point Connection is functionally a kind of form within Point-to-Multipoint Connection.
 Connection via Cisco router: To establish an FCCS link, Q-SIG is used between the system and 
the router.

F-36 FCCS Networking via IP
Operating Procedure
No manual operation is required.
Service Conditions
Service Conditions for FCCS over IPTRK:
1. To send/receive voice information, each node shall use IPTRK circuit card(s). At this time, the IPTRK
cards in the self-node and its connected node(s) can be either in 1-to-1 ratio, respectively (called point-to-
point connection), or in 1-to-n [n=2 or more] relations (called point-to-multipoint connection). For point-
to-point connection, FCH-FGH card is used for FCCS signaling.
2. Be sure to place a router for connections between IP network and IPTRK/FGH card.
3. A maximum of 2 IPTRK cards per unit can be installed. Accordingly, a total of 16 IPTRK cards can be
accommodated per IMG.
4. Only voice and FAX (G3) information can be sent/received via IPTRK card.
5. Only a single FCH-FGH card can be connected to a router (i.e. an FCH-FGH, connected to a router, cannot
control the IPTRK card(s) connected to the other router). Accordingly, redundant configuration of FCH-
FGH is not available.
6. A call cannot be established/routed across multiple IP networks. See the figure below:
7. When multiple IPTRK cards are used for node-to-node connection and all the lines on an IPTRK are busy,
alternate routing is available (see the following figure). However, if a router or FCH-FGH card cannot be
used, all the related IPTRK routes are also made unavailable.
8. When using IPTRK card for point-to-multipoint connection, the port, assignable for FCCS signaling, is
the 1st LEN of each HW block. Other ports are to be used for speech channels.
9. For point-to-multipoint connection, a D-channel, assigned on an IPTRK card, can control the B-channels
of the same card, and also of a maximum of 7 other IPTRK cards.
10. IPTRK-related tandem connection is not available.

FCCS Networking via IP F-36
Service Conditions (cont’d)
11. Any service not available on the FCCS network, is not available with this feature.
12. Tandem Path through function is not provided.
13. This feature supports QoS (Quality of Service) function.
14. 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.
15. When a system message, related to TCP link failure, is created during a call origination or speech, that
calls speech channel is automatically restored via patrol function.
16. When all lines of an IPTRK card are busy, alternate routing to C.O. line or tie line is available. Details on
alternate routing patterns are shown in the following table:
17. PAD can be provided for Receive control only.
18. This feature does not support Broad Band Services H0, H1 of ISDN/CCIS line. This feature supports 1B
only.
19. When FCH-FGH card is used for FCCS signaling, a maximum of 16 nodes can be connected via this
feature.
20. When FCH-FGH card is used for FCCS signaling, the NDM data broadcasting may not work normally via
the FCCS link.
21. This feature does not support any OAI/ACD service.

F-36 FCCS Networking via IP
Service Conditions (cont’d)
Service Conditions for FCCS over IP using Cisco router:
1. DTI (1.5M and 2.0M) interface is used as speech channel.
2. The FCH-FGH card is used as a signal channel. Only a single FCH-FGH card can be connected to a router.
Accordingly, redundant configuration of FCH-FGH is not available.
3. An interface number is assigned to each speech channel and is changed into the TCP/IP port number
between PBX and router for speech channel control.
4. The TCP/IP port number for the TCP/IP (FCCS) packet, which is not controlled at speech channel, should
be different from that for the interface number. The TCP/IP packet is transmitted between PBXs such as
upon remote log-in to another node with Windows MAT. At this time, only the routing for the TCP/IP
packet is performed by the router.
5. The channel number and the connected-to router (router access number as termination number
information) can be recognized by adding Q.SIG message to TCP/IP packet, which makes speech channel
control between PBX and router available.
6. The router applying to FCCS Networking via IP service must be used.
7. The maximum number of digits for the router access code is 16.

4. A group for GROUP CALLING is identical to that of a SPEED CALLING - GROUP [S-23].
5. The number of groups per Module Group for GROUP CALLING and SPEED CALLING STATION/
GROUP [S-21, 23] is limited to the following: 
GROUP CALLING Station Code: 1 digit (X) Maximum 100 Groups 
2 digits (XX) Maximum 10 Groups
6. The number of stations that can be called per group can be set within the following limit: 
a.) Number of Groups x Number of Station Codes = Less than 1,000 
b.) The number of stations per group is assigned in multiples of 10
7. For more information, refer to SPEED-CALLING GROUP [S-23].
8. A station using GROUP CALLING must be allowed individual SPEED CALLING STATION [S-21] and
CALL WAITING - ORIGINATING [C-31] service.

3. Hotline assignments are programmed into System Data via the MAINTENANCE ADMINISTRATION
TERMINAL (MAT) [M-18].
4. The hotline station will hear reorder tone when the called station is in busy, lockout or make busy
condition.
5. When the station called from the hotline has activated CALL FORWARDING - BUSY LINE [C-2], the
call will be forwarded when the called station is busy.
6. When the station called from the hotline has activated CALL FORWARDING - ALL CALLS [C-5], the
call will be forwarded.
7. When the station called from the hotline has activated CALL FORWARDING - DONT ANSWER [C-3],
the call will be forwarded when the called station doesnt answer after a predetermined time interval.

incoming hotline call cannot be placed in the UCD [U-1] queue.
9. The hotline station will hear reorder tone (ROT) if the called station has set CALL FORWARDING - ALL
CALLS/BUSY LINE - OUTSIDE [C-28, 60].
10. ASAT numbers cannot be a connecting station (destination).
11. This feature can be activated via FCCS.
12. Only the station assigned telephone number is available for the station assignment when activating this
feature via FCCS.
13. The station, the Attendant Console/Desk Console (operator call), and the trunk can be a destination for
Hotline.
14. When Call Forwarding - All Calls/Busy Line/Don’t Answer service has been set to the called station, these
features are available for the call to the station.
15. When a calling party encounters a busy station, the call may bridge into the connection depending on the
data assigned by the ASYD command.
Interactions
1. The connecting station does not have to be a HOTLINE station. If the connecting station is busy, the
HOTLINE station will hear reorder tone.

H-1 Hotline
Interactions (cont’d)
2. CONSULTATION HOLD [C-17]: The HOTLINE station may put the destination station on
CONSULTATION HOLD [C-17]. In this state, the HOTLINE station may make an outgoing call, and is
therefore affected by CLASS OF SERVICE-INDIVIDUAL [C-15]. 
3. CALL WAITING-ORIGINATING [C-31]: A HOTLINE will not be allowed to camp-on to a busy
destination station.
