2.2 DESCRIPTION
Patton's new Voice/Data QuikConnect Module (Model no. IM1/J)
extends the functionality of its KiloModem products by allowing voice,
fax and data traffic to be carried over one transmission circuit. The
VDQM supports user interfaces for G3 fax, synchronous data and
PSTN or compressed voice traffic on one module.
Two RJ11 voice/fax ports support FXS, FXO and G3 fax while using
just 64Kbps of bandwidth. Each VDQM also provides a universal data
port that is user-configurable for V.35, RS232/V.24 and RS-530
interfaces. Inserted in the KiloModem products, the VDQM combines
voice/data/fax traffic onto a typical 2-wire or 4-wire circuit at speeds up
to 768kbps with distances up to 17.4 km.
The VDQM is the perfect solution for connecting remote branches or
satellite offices which require voice, fax and high-speed data
communications. Use a pair of VDQMs to connect a telephone and fax
machine in a remote branch office to a PBX in the head office. Serial
data traffic shares the same 2-wire interface and flows for free !!!

3.0 CONFIGURATION
The Model IM1/J VDQM is equipped with three sets of eight DIP
switches, which allow configuration of the unit to a wide variety of
applications. This section describes switch locations and explains all
possible configurations of the VDQM. Please refer to the appropriate
baseband modem (1092, 1093, etc) user manual to configure the
baseband modem.
3.1 CONFIGURING THE HARDWARE DIP SWITCHES
The 24 external switches are grouped into three eight-switch sets,
and are externally accessible from the underside of the VDQM printed
circuit board (See Figure 1).
The three sets of DIP switches on the underside of the Model
VDQM will be referred to as S1, S2, and S3, as shown above. Figure

This section tells you how to install the VDQM
QuikConnect™
module into the baseband modem, as well as how to connect the voice
and the data ports.
4.1 INSTALLING THE
QuikConnect™
MODULE
Each QuikConnect Module™ has a 50-pin card edge connector on
one side and an ethernet interface on the other. The instructions below
describe how to remove the existing QuickConnect™ Module and how
to install the new IM1/I module. If your base unit does not have an
existing QuickConnect™ already installed, please skip to section 4.1.2.
4.1.1 Removing the Existing
QuikConnect™
Module
1) Turn the power switch off. Leave the power cord plugged into a
grounded outlet to keep the unit grounded.
2) Loosen the two thumbscrews on the module by turning them
counterclockwise.
3) Grasp the two thumbscrews and gently pull the module from the
unit. Apply equal force to the thumbscrews to keep the module
straight during the removal process
7
4.1.2 Installing the New
QuikConnect™
Module
1) Make sure the power switch on the base unit is off. Leave the
power cord plugged into a grounded outlet to keep the unit
grounded.
2) Hold the module with the faceplate toward you and align the
module with the guide slots in the rear panel of the base unit.
3) While keeping the module’s faceplate parallel with the base unit
rear panel, slide the module straight in–so that the card edge
contacts line up with the socket inside the chassis. Figure 3
(below) shows how a
QuikConnect™
Module plugs into the rear
of the base unit.
NOTE: The card edge connector should meet the socket when
it is almost all the way into the chassis. If you encounter a lot of
resistance, remove the module and repeat steps 2 & 3.
4) With the card edge contacts aligned with the socket, firmly seat
the module by using your thumbs to apply pressure directly to
the right and left edges of the module faceplate. Applying
moderate and
even
pressure should be sufficient to seat the
module. You should hear it “click” into place.
5) To secure the module in place, push the thumbscrews into the
chassis and turn the screws clockwise to tighten.

4.2 CONNECTING TO THE VOICE PORTS
Both voice ports utilize a Data Access Arrangement (DAA) to
interface with telephone equipment. Both ports also utilize an ADPCM
CODEC to convert voice to digital information. The voice ports (V1 and
V2) use integral RJ-11 connectors. The FXS and FXO ports look the
same on the back of the VDQM
QuikConnect™
Module. Each is
shown on the rear of the VDQM module (See Figure 4, below).
Voice Port 1: Port 1 is permanently defined as a 32Kbs channel
conforming to G.721, capable of supporting normal
speech and Fax transmissions up to 14.4Kbs.
Voice Port 2: Port 2 is permanently defined as a 24Kbs channel
conforming to G.723, intended for voice transmission
only.
4.2.1 Identifying FXS/FXO Voice Modules
The VDQM is factory defined as a FXO (Foreign Exchange Service)
or FXO (Foreign Exchange Office) on both voice ports at the factory. To
determine the factory configuration of your VDQM, look at the label on
the inside of the rear panel. You will see one of the following Model
number codes, plus a serial number.

Warning! Connecting the FXS port of the VDM
to a telephone line WILL damage the VDM and
possibly the telephone line. ONLY connect
telephones or fax machines (or similar
equipment) to the FXS port.
NOTE! The FXO ports are designed to be
connected to a PBX (or similar equipment). If
you wish to connect the FXS ports directly to
PSTN, you MUST obtain approval from the PTT.
4.3 CONNECTING TO THE DATA PORT
The VDQM universal interface data interface is configured as DCE
(Data Circuit-Terminating Equipment). It may be configured to
transmit/recieve V.35, EIA-232 or EIA-422 electrical signals by
appropriately setting switches S1 and S2 (See Section 3.2).
As a DCE, the High Density 26 pin data port is designed to connect
directly to DTE (Data Termination Equipment), such as a router. Refer
to the pin assignments in Appendix C to construct a cable to connect
your DTE or DCE equipment. You may also purchase a connecting
cable directly from cable from Patton Electronics.
4.4 CONNECTING TO AC OR DC POWER
Instructions for connecting the power supply Universal Interface

5.0 OPERATION
Once the VDQM is installed, it should operate transparently. This
sections describes FXS and FXO power-up, and general operating
instructions.
5.1 GENERAL OPERATING INSTRUCTIONS
Both voice ports utilize a Data Access Arrangement (DAA) to
interface with the telephone line. Both ports also utilize an ADPCM
CODEC to convert the voice to digital information.
The FXS configuration (Model IM1/JS) has the capability to
generate battery voltage and ring signal. The battery voltage in the
"On-Hook" condition will be 47 V +/- 10%. In the "Off-Hook condition
the circuit will supply the required current which meets the country of
installation's V/I curve in accordance with NET- 4.
The ring signal has the capability to drive a 1 REN load. This
capability will typically allow for one phone and an extension to be
connected on a single port or to a single phone with a line length up to
1700 feet since most phones have a REN less than 1. This will allow
the unit to be placed in a phone closet if desired, as opposed to sitting
on a desk.
Dialing from an FXS port to an FXO port is accomplished via the
voice channel. DTMF digits generated by the phone connected to an
FXS port are transmitted to the FXO port. Dial Pulse dialing is not
permitted. Dialing between two FXS ports is not required.
5.2 OPERATING THE SYNCHRONOUS DATA PORT
The synchronous data port is a variable rate Universal DCE port.
Since both voice ports and framing/signaling information require 64Kbs,
the remaining bandwidth is used for the data port.
The physical interface of the Data Port is a female, High Density
DB-26. The electrical interface is user configured as a V.35, EIA-232,
or EIA-422. The configuration is accomplished via dip switches on the
module. At present, the design uses a "gapped" clock approach. The
clock sent from the module to the DTE terminal is halted during voice
and framing transmission. With the gapped clock approach, the clock
period of the host module is the period of the DCE clock. The effective
data rate at the DCE port is the host data rate minus 64Kbs.
5.3 FXS to FXO APPLICATIONS:
Figure 5 depicts a typical FXO to FXS application. A Model 1092
with an FXS VDQM acts as an extension of two PSTN phone lines,
which is connected to the 1092 with an FXO VDQM. In this example,
calls dialed into 555-1111 will automatically be sent to the fax machine
connected to Port 1 of Unit 2. When the handset of the phone
connected to Port 2 of Unit 2 is lifted, the phone line of Port 2 Unit 1 will
go off hook, passing dial tone and allowing for DTMF dialing. A router
connected to the Data port of Unit 2 can control the modem connected
to the data port of Unit 1.

5.4 FXS to FXS APPLICATIONS:
Figure 6 depicts a typical FXS to FXS application. The fax
machine connected to Port 1 on Unit 1 will communicate with the FAX
machine connected to Port 1, Unit 2. Phone numbers are not required
for the FXS modules but may be required for the fax machine to
operate properly. If a fax is to be sent from Unit 1 to Unit 2, a 'dummy'
digit can be entered into FAX 1 (NOTE: the fax machines must be set
to ignore dial tone). When the FAX 1 is given the send command, Port
1 unit 1 will go off-hook. The IM1/J will then send signaling bits to Unit
2, instructing Unit 2 Port 1 to ring. Fax 2 will answer the ring and
normal Fax traffic will commence.
To initiate a voice call, either phone is picked up, the phone at the
far end will ring. Once the phone at the far end is answered, both units
will go into voice mode and a conversation can be held.
