Before You Begin
Review this section before performing any of the procedures in this document
Electrostatic Discharge (ESD) Warning
Computer components are extremely sensitive to electro-static discharge (ESD). You
must wear an anti-static wrist strap and install the linecard at an ESD-safe workstation.
Do not open the static-protective bag until necessary. Before removing the linecard from
the static-protective bag, touch the bag to a grounded, unpainted metal surface for at least
two seconds (this drains the static electricity from the bag and from your body). Turn off
and unplug your computer before removing the case.
Gathering Tools and Equipment
Before you begin disassembling the OneBox platform, verify that you have the following
required tools and equipment:
• This document
• #2 Phillips screwdriver
• One or more Dialogic SCbus linecards
• SCbus cable to connect multiple SCbus cards
• If the addition of SCbus linecards increases the number of ports for which you are
currently licensed, a new feature key diskette
• OneBox Telephony Server program CD-ROM
• Dialogic System Software SR5.01 CD-ROM (if applicable)
• If you are installing a D/41ESC and linecords from the telephone system are two-pair
(have RJ-14 plugs), two RJ-11–to–RJ-14 converters for each D/41ESC
• If you are installing a D/160SC-LS, a D/160 adapter cable (with a DB-37 connector
on one end and a RJ-21 at the opposite end) for each D/160SC-LS
• If you are installing a D/160SC-LS and linecords from the telephone system end in

Technical Specifications of Dialogic SCbus Linecards
OneBox functions with linecards designed for the Signal Computing bus (SCbus). The
SCbus is a hardware standard, created by Dialogic and the Signal Computing System
Architecture (SCSA) steering committee, that allows hardware components from
different manufacturers to interoperate in the same platform. Multiple SCbus components
are connected together through the use of an SCbus cable. The following Dialogic SCbus
linecards are approved for use with OneBox:
• D/41ESC 4-port linecard
• D/160SC-LS 16-port linecard
Tables 1 and 2 list the technical specifications of each of the previously mentioned
linecards.
Note The telephone company may require some of these specifications, such as the
FCC registration number, if the linecard is connected directly to central office (CO) lines.

Preparing Dialogic SCbus Linecards for Installation
Before installing a Dialogic SCbus linecard in the OneBox platform, you need to
determine the ports it will handle so you can configure its linecard identification number
and, in the case of the D/41ESC, configure its default line state.
To prepare a Dialogic SCbus linecard for installation:
1. Select the linecard identification number for the linecard by dialing the rotary switch
SW1 (refer to the section “Configuring the Linecard Identification Number,” on the
next page, for instructions).
If you are… Then…
Replacing an existing
linecard with one of the
same model
Select the linecard identification number previously
used by the linecard you are replacing.
Replacing an existing
linecard with one of a
different model
If the replacement linecard is a D/41ESC or D/160SC-
LS linecard, select the linecard identification number
previously used by the linecard you are replacing.
Adding another card Select a new linecard identification number for the
linecard.
2. Set the default line state (hook switch state) of the linecard to offhook.
If you are preparing a… Then…
D/41ESC Flip the SW2 switch position 1 on the D/41ESC to the ON
position.
Refer to “Configuring the Default Line State (Hook Switch
State)” for information about setting the default line state.

Configuring the Linecard Identification Number
Each Dialogic linecard installed in the OneBox platform must be configured with a
unique linecard identification number, referred to by Dialogic as the Board ID, Board
Locator ID, or Board Locator Technology ID. This number, from 0 through 15 hex (1–16
decimal), is used by Dialogic System Software to determine which card is sending a
signal. Linecard identification numbers must be assigned in ascending order to each
linecard starting at 0. OneBox assigns line numbers in ascending order based on the
linecard identification number. For example, if a D/41ESC is installed in the platform and
its linecard identification number is 0, the four ports provided by the linecard will be
assigned line numbers 1–4. If another D/41ESC linecard is installed in the platform and
its linecard identification number is 1, the four ports provided by the linecard will be
assigned line numbers 5–8.
If the linecard will be used to replace an existing linecard and it is the same model
number, be sure to configure this replacement linecard to use the same linecard
identification number.
IMPORTANT
Do not set two linecards to the same linecard ID number. The Dialogic System Software
(device driver) will be unable to locate these linecards.
To set the linecard identification number:
• Dial the rotary switch SW1 to select a unique linecard identification number.
Refer to Figure 1 and Table 3, later in this section, for information about the D/41ESC
linecard; refer to Figure 2 and Table 4 for additional information about the D/160SC-LS
linecard.

Dialogic SCbus Linecard Installation and Replacement
R3B ãAug 2001 Ericsson Enterprise AB 7
Configuring the Default Line State (Hook Switch State)
Each Dialogic D/41ESC linecard has a configurable default line state (hook switch state).
This setting determines how the D/41ESC will respond to incoming telephone calls when
the OneBox platform is turned on but the OneBox server is not running or the Dialogic
System Software device driver is not started.
Dialogic configures each D/41ESC linecard at the factory with onhook as its default line
state, which means the linecard will respond to all incoming telephone calls with ring no
answer (RNA) when OneBox is not running or the Dialogic System Software device
driver is not started.
We recommend that each Dialogic D/41ESC linecard be configured to offhook as its
default line state. When the default line state is set to offhook, the linecard will respond to
all incoming telephone calls with a busy signal when the OneBox platform is turned on
but OneBox is not started or the Dialogic System Software device driver is not started.
To change the default line state to offhook:
• Flip the SW2 switch position 1 on the D/41ESC to the ON position.
Refer to Figure 1, on the next page, for assistance in locating the SW2 switch.

Installing Dialogic SCbus Linecards in the Platform
After the switches have been configured on the Dialogic SCbus linecards, the linecards
can be installed in the OneBox platform.
IMPORTANT
Dialogic SCbus linecards cannot be used in a computer platform containing Dialogic PCI linecards
(includes D/41EPCI and D/240PCI-T1) or Dialogic D/41D cards. If Dialogic PCI linecards or D/41D
linecards are currently installed in the platform, they must be removed prior to installing the Dialogic
SCbus linecards. Dialogic SCbus linecards can be used in conjunction with all Brooktrout fax cards.
To install Dialogic SCbus linecards:
1. Verify that the linecard identification number and the default line state, if applicable,
are set for each linecard (refer to “Preparing Dialogic SCbus Linecards for
Installation” for instructions).
2. Determine the telephone lines each linecard will handle.
3. Select an ISA expansion slot.
If the linecard… Then…
Replaces an existing linecard Remove the existing linecard from the ISA
expansion slot.
Adds ports to the OneBox platform Select an empty ISA expansion slot, remove the
slot’s retaining screw and access cover plate.
4. Insert the card’s edge connector into the bus slot. Apply pressure only to the top edge
of the card, and gently rock the card forward and backward to seat the edge connector
into the slot.
5. Install the retaining screw.
If the screw is not installed when you attach the SCbus cable, it can unseat the card
from the slot.
6. Repeat steps 1–5 for each linecard.

7. If you have more than one SCbus card installed, cable the cards together.
IMPORTANT
Do not place PEB terminators on any cards on the SCbus. The SCbus is self-terminating, so no
terminators are required.
a. Plug the first (end) connector on the SCbus cable to the SCbus connector on the
first SCbus card installed in the platform as shown in Figure 3.
b. Plug the last (opposite end) connector on the SCbus cable to the SCbus connector
on the last SCbus card installed in the platform.
c. Plug a free connector on the SCbus cable to the SCbus connector on each
remaining SCbus card installed in the platform.
8. Replace the cover on the platform and reattach its power cord.

Cabling Dialogic D/41ESC Linecards to the
Telephone System
After D/41ESC linecards have been installed into the platform, they need to be cabled to
the telephone system (switch).
OneBox assigns line numbers in ascending order based on the linecard identification
number. For example, if a D/41ESC linecard is installed in the platform and its linecard
identification number is 0, the four ports provided by the linecard will be assigned line
numbers 1–4. If another D/41ESC linecard is installed in the platform and its linecard
identification number is 1, the four ports provided by the linecard will be assigned line
numbers 5–8. Keep this line number assignment scheme in mind when connecting each
D/41ESC linecard to the telephone system.
To cable Dialogic D/41ESC linecards to the telephone system:
1. Install the linecords from the telephone system to the connectors on the D/41ESC
(refer to the linecard diagram in Figure 4 for channel assignments).
If the linecords from the telephone
system (switch) end with…
Then…
RJ-11 plugs Plug RJ-11 linecords into the RJ-11 connectors
on the linecard.
RJ-14 plugs Plug RJ-14 cords to the RJ-11–to–RJ-14
converter, then plug the RJ-11 cord on the
converter to the RJ-11 connector on the
linecard.

Cabling Dialogic D/160SC-LS Linecards to the
Telephone System
After the Dialogic D/160SC-LS linecards have been installed into the platform and have
been connected to the SCbus cable, they need to be cabled to the telephone system.
OneBox assigns line numbers in ascending order based on the linecard identification
number. For example, if a D/160SC-LS linecard is installed in the platform and its
linecard identification number is 0, the 16 ports provided by the linecard will be assigned
line numbers 1–16. If another D/160SC-LS linecard is installed in the platform and its
linecard identification number is 1, the 16 ports provided by the linecard will be assigned
line numbers 17–32. Keep this line number assignment scheme in mind when connecting
each D/160SC-LS linecard to the telephone system.
To cable Dialogic D/160SC-LS linecards to the telephone system:
1. Connect the D/160 adapter cable to the linecard and tighten the screws.
The D/160 adapter cable, also known as a SA/240 or Amphenol cable, has a female
DB-37 connector and a female RJ-21 (Amphenol) connector. The pinouts for each of
these connectors is shown in Figure 6.
2. Choose one:
If linecords from the telephone
system end with… Then…
RJ-14 plugs Continue to step 3.
RJ-21 (Amphenol) plugs Plug the RJ-21 plug to the RJ-21 connector on the
D/160 adapter cable, then skip to step 5.
3. Connect the D/160 adapter cable to a male RJ-21–to–RJ-14 converter (also known as
a harmonica), shown in Figure 7.
4. Plug the RJ-14 linecords to the RJ-21–to–RJ-14 converter.
Figure 7 displays the channel assignments of the RJ-21–to–RJ-14 converter. It also
