Three-Way Calling - D
term
T-2D
Service Conditions (cont’d)
5. When the additional station answers the held call, the decision to send Override Tone depends on the
originating station service restriction class.
6. The Conference Trunk (CFT) function is required for the node which accommodates the station operating
a three-way conference within the FCCS network.
7. Three-Way Calling can also be established when using the trunk belonging to the remote node within the
FCCS network.
Programming
STEP 1: ASYD
- System Data 2, Index 1, Bits 0 & 1. Consultation Hold allowed or denied. 00: Denied; 01:
Originating and Terminating Calls allowed, Tandem Call Denied; 10: Only Terminating Calls
Allowed; 11: All calls allowed.
System Data 2, Index 6, Bit 2. This Bit remains as data “0”. CALL TRANSFER-ALL CALLS [C-11].
System Data 2, Index 6, Bit 3. Enable add-on ability. This Bit remains as data “0” to allow THREE-
WAY CALLING.
System Data 3, Index 2. Assign data 91H for Normal (N), Hooking (H) values.
STEP 2: ATRK - Assign LENs as Route 909, Digital Conference Trunk. The LEN consists of the following:
Group and level numbers for the digital conference trunk are 210, 213, 216, 221, 224, 227, 232, 235.
STEP 3: MBTK
- Make idle the Digital Conference Trunk
STEP 4: ARRC
- Allow for trunk-to-trunk connections between any two routes that may be used in THREE-
WAY CALLING. Assign these routes for ARI-A-RES: This connection is for a station and two trunks
ARI-D-RES. If the originating party hangs up, the remaining two parties will stay connected.
STEP 5: ARSC - The Route Restriction Class must be constructed so as to allow the station access to the
involved routes.
STEP 6: ASFC
- When Consultation Hold Enhancement is used, assign each station Service Feature Class
(SFC) that allows SFI 138 and SFI 140.
SFI 138: Consultation Hold Enhancement
SFI 140: Send Warning Tone to interrupted parties when three-way calling is established using
Consultation Hold Enhancement
FCCS Programming
This data setting describes only the additional or replacement commands used to activate FCCS
services. When used as an FCCS feature, these commands replace the non-network commands (for
example, AAED is replaced by AAEDN). Note that the data setting for FCCS service varies depending
on the node.
Note
STEP 1: ARRCN
- Allow for trunk-to-trunk connections between any two routes that may be used in THREE-
WAY CALLING. Assign these routes for ARI-A-RES: This connection is for a station and two trunks
ARI-D-RES. If the originating party hangs up, the remaining two parties will stay connected.
STEP 2: ARSCN
- The Route Restriction Class must be constructed so as to allow the station access to the
involved routes.
