5V bus systems.
The RocketModem IV is
available with four or
eight RJ11 modem ports
that can operate at
speeds up to 56 Kbps
and uses on-board user
upgradeable firmware.
RocketModem IV
features include:
• Ring Indicator (RI) status is included on all modem ports
• Individual software controlled modem reset capability
•Speaker
All V.92 modems are analog line devices. The following figure shows when you can
and cannot achieve 56 Kbps.

• V.92 modems can receive data at rates up to 56 Kbps, provided the data is
being transmitted by a digital modem on a digital (e.g., T1 or ISDN) line.
• V.92 modems can send data over analog (twisted pair) phone lines at a
maximum rate of 33.6 Kbps—even if communicating with other V.92 modems.
• The actual data rate achieved depends on the age and condition of the analog
phone lines, and may be lower than 33.6 Kbps.

Installing the RocketModem IV
Use the following procedures to install a single RocketModem IV.
Note: Make sure that you install new adapters one at a time to minimize
installation problems.
Installing the RocketModem IV
European Installations: Before Hardware Installation
Before installing this board, ensure that the power drawn by this board, together
with the host and any auxiliary boards drawing power from the host, is within the
rating of the host power supply. Equipment must be installed such that, with the
exception of connections to the host, the clearance and creepage distances shown
in the following table are maintained between the board and other assemblies that
use or generate the voltages shown in the table. The larger distances shown in
(brackets) apply where the local environment within the host is subject to
Caution
conductive pollution or dry non-conductive pollution which could become
conductive due to condensation (Pollution Degree 3 environments). Failure to
maintain these minimum distances would invalidate the approval.
Note: Obtain advice from a telecommunications safety engineer for a host or other
expansion boards fitted in the host using or generating voltages greater than
300 V (rms or dc).
Minimum Clearance Creepage Voltage
2.0 mm 2.4 (3.8) mm Up to 50 Vrms or Vdc
2.6 mm 3.0 (4.8) mm Up to 125 Vrms or Vdc
4.0 mm 5.0 (8.0) mm Up to 250 Vrms or Vdc
4.0 mm 6.4 (10.0) mm Up to 300 Vrms or Vdc
Safety Notices Installation of inside wire may bring you close to electrical wire, conduit,
terminals and other electrical facilities. Extreme caution must be used to avoid
electrical shock from such facilities. Avoid contact with electrical current by
following these guidelines:
• Use tools with insulated handles.
• Do not place telephone wiring or connections in any conduit, outlet or junction
box containing electrical wiring.
Note: Do not work on your telephone wiring at all if you wear a pacemaker.
Telephone lines carry electrical current.
• Telephone wiring must be at least 6 feet from bare power wiring or lightning
rods and associated wires, and at least 6 inches from other wire (antenna
wires, doorbell wires, wires from transformers to neon signs), steam or hot
water pipes, and heating ducts.
• Before working with existing inside wiring, check all electrical outlets for a
square telephone dial light transformer and unplug it from the electrical
outlet. Failure to unplug all telephone transformers can cause electrical shock.
• Do not place a jack where it would allow a person to use the telephone while in
a bathtub, shower, swimming pool, or similar hazardous location.
• Protectors and grounding wire placed by the service provider must not be
connected to, removed, or modified by the customer.
Do not touch telephone wiring during lightning!

Installing the Hardware
Installing the
Hardware
Use this procedure to install the RocketModem IV.
1. Extract the appropriate driver for your operating system and if desired, print
the installation document. See Before Installing the Hardware
on Page 2, if
you need the driver and documentation.
The device driver is available on the Comtrol CD shipped with the product or
can be located by using Locating Software and User Guides
on Page 5.
You can insert the Comtrol CD, double-click on the driver, and extract the files
to your host system a new subdirectory, for example: \Comtrol.
2. Review the information discussed in Safety Notices
on Page 3 and FCC Notices
on Page 13.
3. Turn your computer off and remove the system unit cover.
Note: For best results we recommend installing RocketModem IV boards one
at a time, to simplify the configuration process.
4. Select an available PCI slot and remove the slot cover.
5. Insert the RocketModem IV in the expansion slot making sure that it is seated
securely.
Note: The RocketModem IV is a full length card. Do not remove the support
bracket during installation. Deformation of the card due to bracket
removal is not covered by the warranty.
6. Re-install the expansion slot cover screw.
Note: When powered up, the RocketModem IV generates significant heat. After
you install and configure the RocketModem IV, make sure the system
cover is closed and the ventilation fan is unobstructed. If you install
more than one RocketModem IV, you may want to add an additional
internal cooling fan.
7. Connect standard RJ11 (telephone) cables between the
RocketModem IV ports and the phone line jacks. See Modem Cables
on Page 16 if you need information about the RJ11 pinouts.
The modem ports on the RocketModem IV mounting bracket are
numbered as shown in the illustration at right. The port on the “top”
edge of the board is modem Line 1, and the port at the “bottom” edge
of the board, nearest the bus connector, is Line 8.
8. Power up the computer, and install and configure the device driver
for your operating system using the software installation and
configuration document for your operating system (Before Installing
the Hardware on Page 2).
After you have successfully installed one RocketModem IV, you can
install additional RocketModem IV boards by repeating this process.

Using RocketModem IV Features
The following subsections discuss using the speaker, Caller ID, Voice mode, and
Low Power Sleep mode.
Note: See the software installation document (Before Installing the Hardware
Page 2) for your operating system to reset a modem ports.
Using RocketModem IV Features
on
Using the Speaker The RocketModem IV includes a speaker, which enables you to listen to the call in
progress and helps you determine the state of the phone line and the modem. This
speaker is shared by all modems on the board and can be controlled for individual
modems by use of AT commands.
The following table lists some of the more commonly used speaker-related AT
commands. For a complete list, see the Conexant AT Commands for CX81801
SmartV.XX, CX06833 SMXXD, CX81300 SmartACF, and CX06827 SCXXD
Modems Reference Manual, Doc. No. 102184B: July 1, 2003.
AT
Command
Usage
ATL (0, 1, 2, 3). Enter the ATL n command to set the modem speaker
L
volume, where 0 is the lowest level and 3 is the highest level.
This value is written to S22 bits 0 and 1.
ATM (0, 1, 2, 3). Enter the AT Mn command to set the modem speaker
mode. This value is written to S22 bits 2 and 3. Valid values are:
• M0 - Speaker always off
M
• M1 - Speaker on when making call but off when receiving carrier
• M2 - Speaker always on
• M3 - Speaker off when making call but on when answering
&V
Enter AT& V to display the contents of the S-Registers and check the
state of the L and M registers.
Using Caller ID The RocketModem IV supports the use of Caller ID services through use of the
+VCID and +VRID commands.
The following page numbers are referenced from the Conexant AT Commands
Reference Manual.
• To enable formatted caller ID, use at+vcid=1.
For detailed information, see Section 3.2.1: Generic Modem Control: +VCID
Caller ID (CID) on Page 3-3.
• To enable formatted retrieval of the last caller information, use at+vrid=0.
For detailed information, see Section 3.2.1: Generic Modem Control: +VRID
Report Retrieved Caller ID (CID) on Page 3-4.
Additional information for these commands, see Table 6-1: Voice Commands on
Page 5-1 and Table 6-6: Events Detectable in the Voice Mode per V.253. Page 5-13.
Using Voice Mode After being put into voice mode, characters entered from the telephone set are
passed on to the application. Enable voice mode using this command: at+fclass=8.
