PC Attendant Console Features
Strata DK General Description    5/99107
Split/Switch Button
The Split/Switch
 button is used to alternate between source and destination parties; the two 
parties are kept separate. This feature can only be used during a three-way conference (console, 
source and destination party). The parties can be connected on outside lines only, either on [DN] 
lines only, or on a combination of outside and [DN] lines. The Split feature does not work on four-
party conference calls.
Three-way Calling
Three-way Calling enables an Attendant to talk simultaneously with the source and destination 
parties. This feature requires a connection with a station user or outside caller, including a party on 
Consultation Hold.
Through Dialing
This feature lets an Attendant provide outgoing call privileges to a restricted station user. On a 
call-by-call basis, the Attendant can access otherwise denied trunks and then pass the dial tone to 
the station user. The station user can then complete the call dialing procedure. Through Dialing can 
also be applied to callers using DISA and incoming Tie trunks.
Transfer Direct to Voice Mail
A button on the DK PC-ATT enables direct transfer of outside callers to a station user’s voice 
mailbox. This is more efficient than directing a call to a busy station which, if call forward was set 
to voice mail, would then forward. This is also helpful when the Attendant knows a station user is 
unavailable. This feature is also useful the called party does not own a station set, but they do have 
a voice mailbox. The Attendant can release the call when voice mail answers.
Trunk Group Busy Indication
This feature shows the trunk groups and whether all members of the group are busy. Trunk groups 
with no members are always shown busy.
Trunk Group Control
Outgoing CO line groups can be restricted on an as-needed basis. This feature also restricts 
outgoing calls on two-way CO line groups. This enables the Attendant to control outgoing traffic 
on heavily-used line groups during busy hours.
Volume Control
The Vol Up and Vol Dn buttons adjust the console’s ringing and handset/headset volumes. 
Windows PC Operation
The Strata DK PC-ATT software runs on the computer as an application within Windows. Toshiba 
recommends using a dedicated PC for the console; however, other applications can run 
simultaneously on the same PC. The PC can toggle between Attendant Console mode and other 
applications.
The console commands are similar to other Windows applications, making training easier for 
previous Windows users. Either a mouse or keyboard can be used for console operation.

(Off-premises Station)
1. Only PESU circuits 1 and 2, and RDSU circuits 1~4 provide Off-premises Station (OPS) capability. PESU must use OL13A or 
equivalent line conditioning for OPS connection. RDSU must use OL13A or OL13B if providing –24 volt loop voltage. If 
equipped with the –48 volt loop option PCB (R48S), OL13A, OL13B, or OL13C may be used for OPS connection.

2. When ordering DS-1/T1 circuits, six items must be specified:
lThe number of channels per T1 circuit, fractional increments are normally 8, 12, or 16 channels, full service is 24 channels. 
Unused channels must be bit-stuffed.
lType of CO line assigned to each channel: Loop Start, Ground Start, Tie (Wink or Immediate Start), DID (Wink or 
Immediate).
lFrame Format Type: Super Frame (SF) or Extended Super Frame (ESF). The T1 provider normally specifies the Frame 
Format to be used, either is adequate for DK424 CO digital voice lines. ESF provides a higher level of performance 
monitoring, but requires trained personnel and the ESF CSU normally costs more than an SF only CSU.
lLine Code Type: Alternate Mark Inversion (AMI) or Bipolar 8 Zero Substitution (B8ZS). The T1 provider normally 
specified the Line Code to be used, either is adequate for DK424 T1 CO digital voice lines.
lThe customer may have to provide the Channel Service Unit (CSU) to interface the DK424 T1 circuit to the Telco T1 circuit. 
(CSUs are a Telco requirement.)
lRDTU Network Channel Interface Codes: 04DU9-BN, 04DU9-DNZZ, 04DU9-1SN, 04DU9-1KN, 04DU9-1ZN.

3. For information on how to order ISDN PRI/BRI circuits, you should refer to the Toshiba ISDN Training CBT. ISDN circuits 
may require a customer-provided CSU for PRI and/or Terminal Adapter or Network Terminal units for BRI. In U.S. CSU/TAs 
must be UL-listed in the U.S. In Canada, they must be CSA certified.
