Revision 1.0
As explained in CHAPTER 1, the installed system (IPX-U) can have a connection also with other IPX and/or IMX
series via the FCCS link. If this is the case, perform the following tests, too, by referring to the “Fusion Network
System Manual”:
1. FCCS (Fusion Call Control Signal) Connection Tests between the installed system and other IPX and/or
IMX series
- Station-to-Station Test
- ATTCON Connection Test
- Line (LC, ELC, DLC card) Connection Test
- 3-party Conference Trunk Function Test
2. FCCS Alternate Routing Test

Seizure of trunk to be tested
When seizing from a station Place the trunk to be tested into idle state, and make busy all 
other trunks.
Station “A” dials the number for station “B” in the PBX-B
When seizing from an 
ATTCONAn ATTCON sets up the connection with a specific trunk 
designated by Individual Trunk Access for CCIS TRK 
service and dials the number for Station “B” in the PBX-B.
Call termination to Station “B” in 
the PBX-BThe call terminates to Station “B” via a CCIS Tie Line.
Check of  speech  conditions After the call has been answered at the ATTCON, check the 
speech conditions including speech level, presence of noise 
and one-way speech state.

have been checked and a fault has 
been detectedPerform fault localization procedure when a fault has 
occurred to CCIS Tie Line (See Procedure A on the next

START
Test the trunks in the primary route 
one at a time.Make busy all trunks in the primary route except the trunk to

PAD Setting
1. Analog Trunk
a) For an outgoing/incoming call via a Tie Line:
 Via MAT command “ARTD” and switch settings on the TLT circuit card.
b) For a tandem Tie Line connection:
 Via command “APAD” or switch settings on the TLT circuit card(s).
At both the originating and terminating offices, an 8 dB PAD is set for the EMT route via the “ARTD” command or
switch settings. At the tandem office, a 4 dB PAD is set for the terminating and originating sides of each EMT route
via command “APAD.”
Through this arrangement, an 8 dB PAD is in service for outgoing and incoming connections, and 4 dB PADs are in
service for each line in a tandem connection (total: 8 dB). This arrangement is shown in Figure 049-1.

2. Digital Trunk
a) For an outgoing call to/incoming call from a Tie Line:
 Via command “ARTD”/“ACRD” 
Note
b) For a tandem Tie Line connection:
 Via command “APAD”/“AFPD” 
Note
Note:
Command “ACRD” and “AFPD” are available for the Fusion network only. For details, refer to the “Of-
fice Data Specification.”
At both the originating and terminating offices, 0 dB is set to the outgoing side and 8 dB is set to the terminating of
the DTI/CCT route via “ARTD”/“ACRD” command.
At the tandem office, 0 dB is set for both the terminating and originating sides of each DTI/CCT route via “APAD”/
“AFPD” command.
This arrangement is shown in Figure 049-2.
