• All power supply data is stored in the power supply Inverter Module’s class information base (CIB) tables in
1
the power supply. This data is accessible directly via the power supply’s LCD Display (see the power supply’s
technical manual for details). The CIB tables are the source of the transponder’s data.
2
• The DM3X Transponder contains both SCTE-HMS Management Information Base (MIBs) and the proprietary
Alpha MIB tables. The SCTE-HMS MIBs are industry standard MIB tables that store power supply, battery and
generator data from the CIB tables (See Section 6.0, Data Management). The Alpha MIB contains all the data of
the SCTE-HMS MIBs plus additional power supply settings and values as well as the transponder’s conguration
values.
3
• A xed or stationary external generator or additional power supplies may be connected through the COM
(AlphaBus) port permitting monitoring locally through the Ethernet connector or remotely via the Web page or
SNMP-based Network Management System.
4
• Power supply and transponder parameters can be monitored and set locally using a personal computer and a
standard Ethernet cable.
5
• The transponder transmits data via its cable modem directly over the Coax or Hybrid Fiber Coax network.
6
•The Cable Modem Termination System (CMTS) is the bridge between the cable network and the TCP/IP network.
The transponder’s cable modem communicates over the HFC network to the CMTS.
7
• The Dynamic Host Control Protocol (DHCP) server needs to be provisioned with the transponder’s cable modem
CM MAC address and the MAC address needs to be assigned a DOCSIS Conguration File.
8
• The DOCSIS Conguration File and rmware les should be available in the Root Directory of the Trivial File
Transfer Protocol (TFTP) Server.
9
•The Time of Day (TOD) Server provides the cable modem with the current date and time.
10
• A Network Management System (NMS) or MIB Browser allows remote monitoring, control, and conguration of
the transponder, power supply, and connected device parameters. Alarms and traps can be set and monitored.
11
•The power supply and generator data may be accessed remotely through the transponder’s Web page by placing
its IP address into a standard Web browser.
12
• The following ports of the Transmission Control Protocol/Internet Protocol network must be opened: 161=SNMP,
162=SNMP, Traps, 69=TFTP, 80=HTTP, 37=TOD.

2.2 Network Connectivity
The transponder’s cable modem must be provisioned to be recognized by the CMTS as a valid device to be assigned an
IP address from the DHCP server, to locate the TFTP and TOD servers and to communicate with the SNMP management
server (trap receiver). The DM3X Transponder must be provisioned in the cable system to allow it to be recognized by the
CMTS, receive an IP address, TOD, TFTP les and communicate with the SNMP management system.
In single IP congured devices, data from both the cable modem and power supply are accessed and managed through
the modem’s IP address on the secure private modem network. The transponder is not accessible from the public
Customer Premises Equipment (CPE) network. Consequently, the Network Management System (NMS) that monitors the
power supplies must have access to the same private modem network.
CMTS and system vendors use dierent security methods to ensure network integrity, but common considerations are:
• Network MAC ltering may have to be modied to allow the cable modem OUI of 00:90:EA for North America, and
00:03:08 for European models.
• For SNMP access, UDP ports 161 and 162 must not be blocked.
• For TFTP access, port 69 must not be blocked.
• For HTTP access, port 80 must not be blocked.
• For TOD access, port 37 must not be blocked.
• Firewalls must allow TFTP, DHCP, SNMP and TOD communication to the cable modem.
• If the address of the TFTP or TOD server is dierent than the DHCP server, the response from the DHCP server
must contain the TFTP and TOD addresses.
2.3 System Conguration and Installation
NOTICE:
Before installation, read all of Section 2.0, Overview.
DM3X Transponder installation and setup is comprised of three basic steps:
1. Configuring the Network: Provisioning the DHCP Server with the transponder’s MAC address and assigning it a
DOCSIS Configuration File.
2. Setting Options: The DM3X Transponder is designed for out-of-the-box, “plug and play” operation, but non-default
settings such as SNMP trap destination addresses may be required for the Network Management System (NMS).
SNMP trap addresses can be set automatically via the DOCSIS Conguration File per RFC 4639 (IPv4), or
through SNMPv3 Notication settings (IPv6), while proprietary options may be set through type-11 TLV entries.
3. Field Installation of the DM3X Transponder into the power supply, connecting the battery string wire harnesses,
Tamper, Environmental Control (as applicable), RF drop cable and verifying operation.
These steps can be performed independently of one another. However, conguring the network prior to eld installation
will allow the installation to be veried while personnel are still on-site. Performing eld installation before network
conguration and before the installation can be veried, might result in additional eld service calls to correct mistakes.
Carefully read the following section in order to understand the dependencies within the system before performing system
conguration or hardware installation.

3.0 Network Configuration
3.1 Provisioning the DHCP Server with the MAC Addresses
On the DHCP server, assign the cable modem’s CM MAC address with a DOCSIS Conguration File to set modem
communication options. (See Section 3.3, The DOCSIS Conguration File for instructions on how to create a DOCSIS
Conguration File).
The CM and CPE MAC addresses are located on the DM3X Transponder and on the packing slip, see below. The CM
MAC address may be labeled as the RF MAC address on some DM3X units.

3.2 Establishing IP Connectivity
The DM3X Transponder supports the CableLabs DOCSIS 3.0 IPv6 implementation. The main benet of IPv6 is its
expanded addressing capability, increasing the address space from 32 to 128 bits, providing virtually unlimited number
of networks and systems. The DM3X Transponder determines the IP provisioning mode via the CableLabs SNMP MIB
parameter docsIf3CmMdCfgIpProvMode (SNMP OID: 1.3.6.1.4.1.4491.2.1.20.1.31.1.1). The DM3X will support the
following congurable IP Provisioning Mode Override policies:
• Honor MDD: The cable modem of the DM3X unit will acquire an IPv6 or IPv4 address as directed by the MAC
Domain Descriptor (MDD) message for provisioning and operation.
• IPv4 only: The cable modem of the DM3X unit will acquire a single IPv4 address for the CM management stack,
overriding the TLVs in the MDD message.
• IPv6 only: The cable modem of the DM3X unit will acquire a single IPv6 address for the CM management stack,
overriding the TLVs in the MDD message.
3.3 The DOCSIS Conguration File
A cable modem’s DOCSIS Conguration File is a type-length-value (TLV) le that contains important operational
parameters as dened by the DOCSIS standards. It provides certain settings for the cable modem. In addition to standard
entries, settings in the DOCSIS Conguration File should include the modem’s community strings and if an upgrade is
necessary, rmware upgrade parameters. Place the Conguration File in the TFTP root directory.
The transponder’s cable modem interface can support both IPv4 and IPv6 addressing schemes. The required DOCSIS
Conguration File operational parameters will dier depending on company policies, cable modem rmware versions and
IP addressing schemes. The following DOCSIS Conguration File details listed in this manual are general guidelines.
Please consult the published DOCSIS Specication resources (CableLabs) for additional DOCSIS Conguration File
details and guidelines.
To build a DOCSIS Conguration File, use a DOCSIS TLV editor program.
See the example Conguration Files in Sections 3.3.5 and 3.3.6.
NOTICE:
The modem community strings should be set in the DOCSIS Conguration File. Failure to set community strings
will result in a less secure system. For automatically updating modem rmware with the DOCSIS Conguration File,
see Section 5.1, Upgrading DM3X Modem Firmware.

NOTICE:
DOCSIS conguration les vary from system to system. Take into consideration your company’s policies and test
the le on a local system prior to widescale deployment.
In previous versions of the DM product line, an additional conguration le (also known as a Setup File)
could be used for distributing custom Alpha MIB settings to all DMs on a network. This is still the case,
with the only dierence being the name of the le, which for the DM3.0 Series is atidoc33.cfg. It may be
used if preferred but is not required.
The DM3X Transponder will attempt to download a TLV-formatted le ‘atidoc33.cfg’ from the modem’s provisioning TFTP
server at start up and every 24 hours thereafter. The atidoc33.cfg proprietary conguration le is optional and provides an
alternative method to the modem’s DOCSIS conguration le for deploying Alpha proprietary SNMP MIB parameters to
eld-installed DM3.0 Series Communications Modules.
The atidoc33.cfg le should be used if the following conditions are true:
1. Non-default settings, such as SNMP Trap Destination Addresses need to be distributed to all DM3X
Transponders.
2. The operator does not desire to place Alpha-proprietary parameters into the modem’s DOCSIS conguration le.
NOTICE:
The recommended method for setting the SNMP trap address(es) is through the modem DOCSIS conguration le
(See Section 3.3, The DOCSIS Conguration File). Alpha-proprietary parameters may also be set through the
modem’s DOCSIS conguration le, eliminating the need for the atidoc33.cfg proprietary conguration le.
To build the atidoc33.cfg le, enter the desired SNMP OIDs and values from the Alpha MIB into a TLV le as TLV type-11
entries using a TLV editor (Refer to sample entries below). The DM3X proprietary conguration Setup le must be named
“atidoc33.cfg” and placed in the root directory of the TFTP server. DM3X settings are updated according to values dened
in this le at start up and after every 24 hours of operation.
Sample atidoc33.cfg Entries:
By default, the DM3X Transponder will download the atidoc33.cfg le from the provisioning TFTP server every 24 hours.
However, these settings may be adjusted per the tables below by placing the respective SNMP varbinds into the modem’s
DOCSIS conguration le.

4.0 Web Interface
Overview
The DM3X provides an embedded Web server interface to allow operations personnel the ability to connect locally or
remotely via TCP/IP over Ethernet with a laptop/computer to verify the status of common data points and to congure
various operating parameters. Unless otherwise stated, data values shown in the gures throughout this section are
shown for illustration purposes only.
4.1 Local Web Server Access
The DM3X Ethernet port (comparable to the Craft port on some transponder models) will typically be used as a local
connection point allowing the user to connect directly to the DM3X Web server interface to verify/congure common
communication parameters and view power supply status and battery values. The Ethernet port on the DM3X is a fully
functional standard Ethernet port, capable of providing all the functionality of any standard Ethernet connection.
To access the DM3X Web server locally utilizing
a Web browser, use the following procedure:
NOTICE:

5.0 Upgrading Firmware
5.1 Upgrading DM3X Modem Firmware
The rmware is upgraded using standard DOCSIS methods as dened in RFC4639.
There are two ways to upgrade the modem’s rmware: By directly setting the appropriate MIB parameters in the
docsDevSoftware branch, or by including the appropriate SNMP parameters and values in the modem’s DOCSIS
Conguration File, stored in the TFTP root directory.
Both methods are explained below.
5.1.1 Identifying the Modem and Obtaining Firmware Files
The cable modem rmware in the DM3X requires its own rmware and manufacturer’s Code Verication Certicate (CVC
le).
Contact Alpha Technologies Services, Inc. to obtain the latest rmware and manufacturer’s CVC les.
The IP address of the TFTP server from which the rmware
will be downloaded. This OID has been deprecated, refer to
docsDevSwServerAddress (OID:1.3.6.1.2.1.69.1.3.7.0).
Set to the lename of the rmware le. Example:
[“rmwareImage.bin”]
1 = Initiate upgrade (manual method)
2 = Upgrade on next reboot (Cong File Method)
3 = Ignore update
1 = TFTP download is in progress
2 = Last upgrade was performed at reboot
3 = Last upgrade was initiated by setting
docsDevSwAdminStatus to “1”
4 = Firmware upgrade failed
5 = Other
The current version of rmware installed in the modem
The type of address (IPv4, IPv6) of server used for upgrades
The IP address of the server from which the rmware will be
downloaded. A set of this object to an IPv4 address will result
in also setting the value of docsDevSwServer to that address.
If this object is set to an IPv6 address, docsDevSwServer is set
to 0.0.0.0. If docsDevSwServer is set, this object is also set to
that value.
The Transport protocol to be used for software upgrades:
1 = TFTP
2 = HTTP

6.0 Data Management
6.1 SCTE-HMS MIBs
The DM3X remotely reports power supply data and alarms using the Simple Network Management Protocol (SNMP) over
the DOCSIS (Data Over Cable Service Interface Specication) communications standard. The DM3X typically reports into
a centralized Network Management System (NMS) through a standard collection of data access points referred to as the
SCTE-HMS Management Information Bases (MIBs). The NMS polls the DM3X for power supply data with the option of
having the transponder send SNMP traps in the event that an alarm condition occurs.
The following MIB (Management Information Base) les are required for the NMS or SNMP Manager to collect data from
the transponders. These les can be found on the Society of Cable Telecommunications Engineers (SCTE) Web site
www.scte.org. There are dependencies between MIB les so they should be compiled in the order listed below:

6.2 SCTE-HMS MIB Alarms
6.2.1 SCTE-HMS Congurable Alarms
The HMS discrete and analog alarms provide the capability to monitor and alarm various power supply and environmental
conditions and measurements. The alarms in the SCTE-HMS propertyTable and the discretePropertyTable can be dened
and set to provide a custom monitoring system.
The following section provides an example and detailed information on how to set values and enable or disable alarms in
the MIB tables. For ease of reference they are in this sequence:
• An example of how to set a temperature alarm
• A table to help convert the desired reported alarm states to hexadecimal for setting the MIB
• Commonly monitored parameters and recommended values
Example:
The alarms for psTemperature on the following page are set so that the normal temperature range is from 30°C to 45°C.
If the temperature rises above 45°C, a casHI alarm will be sent to the alarmTable. Anything over 50°C is considered a
critical condition and will generate a casHIHI alarm. If the temperature falls below the normal level of 30°C, casLO will be
generated and if it continues to drop below 0, a casLOLO will be generated. The temperature must rise above the LOLO
limit plus the deadband value of 3°C before the casLOLO alarm will change to a casLO. The alarmEnable eld is set to 0F
Hex to monitor and alarm for all conditions.

DM3XAlarm Cloning & Distribution
SCTE-HMS Alarm settings can be distributed automatically to all DM3X Transponders on the network. Use the following
procedure to congure and distribute the alarm settings.
1. Select the desired SCTE-HMS alarm settings on a master DM3XTransponder.
The SCTE-HMS-PROPERTY MIB denes a method for setting thresholds for analog and discrete values that can be
used for setting traps or alerting a Network Management System when those thresholds are compromised. There are two
SCTE-HMS SNMP MIB Tables where these values are congured:
propertyTable OID: 1.3.6.1.4.1.5591.1.1.1
This table is used for setting thresholds for analog properties such as input & output voltages, individual battery voltages,
currents and temperature.
discretePropertyTable OID: 1.3.6.1.4.1.5591.1.1.3
This table is used to set alarm parameters on discrete conditions such as tamper on/o, major/minor alarms and various
inverter status conditions.
Full explanations of these MIB tables and their settings can be found by reading the SCTE-HMS-PROPERTY MIB. The
MIB table alarm settings can be changed to desired values using a SNMP MIB browser or status monitoring software.
Once the tables are congured with the desired alarm settings, proceed to Step 2 on exporting the “AlarmSettings.acf” le.
56704-939-B10-001 Rev. A5 (06/2019)
Page 57
6.0 Data Management, continued
2. Export the “AlarmSetting.acf” le of the master transponder’s alarm settings.
3. Connect to the Web page of the master transponder.
4. Navigate to the Advanced Conguration menu and select the HMS Alarms page.
5. Verify the alarm settings dened in Step 1 are displayed in the propertyTable and discrete PropertyTable. If further
changes to the alarm settings are required, refer to Step 1.
6. Click on the Export button at the bottom of the HMS Alarms page.
7. When prompted, refer to Section 4.3.1, Web Interface Security Levels for the applicable User Name and Security
Password.
8. Download the “AlarmSettings.acf” le to the TFTP root directory. If desired, the le may be renamed.
9. Distribute the “AlarmSettings.acf” le to other transponders.
10. The “AlarmSettings.acf” le is distributed to other transponders by setting the following Alpha MIB parameters
to the indicated values. This can be done to an individual transponder using a MIB browser, or to multiple
transponders by placing the SNMP OIDs into the modem’s DOCSIS conguration le or the proprietary atidoc33.
cfg conguration le.
Table 6-6, Status of Alarm Setting Download Parameters
Verify the transponder’s SCTE-HMS property tables have been updated by viewing the HMS Alarms Web Page, status
monitoring system or SNMP MIB browser.

6.2.2 SNMP Traps
Use of SNMP Traps allow the network manager to set conditions (alarms) under which the device (or devices)
autonomously reports to the headend the existence of the pre-congured event. The type of event determines the level of
action to be taken.
1. Verify the IP address of the trap destination server(s) has been configured.
• If the trap destination server requires conguration, refer to Section 3.3.3 Setting SNMP Trap Destination IPv4
Method, and 3.3.4 Setting SNMP Trap Destination Addresses—IPv6 Method, for instructions.
2. Alarms must be congured. SNMP alarm traps sent by the transponder are formatted according to the SCTEHMS-ALARM-MIB specication with the following information included:
• SNMP Trap community string:
• commonTrapCommunityString, OID 1.3.6.1.4.1.5591.1.3.1.11.0
• Default value is “public”
Example Alarm Trap:
The example below is a psTamper alarm trap indicating a discreteMinor alarm: Tamper is open. Data from the raw trap will
appear as shown below. Refer to Table 6-7, SNMP Alarm Trap Varbinds and Explanations, for denitions of the varbinds.
Optional user-congurable parameter that is often used to provide a unique logical
name, or even the physical address of where the Communications Module is
installed.
This varbind was designed by the SCTE-HMS committee with the intention of being
used by sophisticated trap interpreters. The information is “coded” within the octet
strings:
Octet 1-4: POSIX Time of alarm occurrence (most signicant byte rst)
Octet 5: Alarm Type (See description below)
Octet 6: Contents of commonNeStatus immediately after alarm occurred
Octet 7-m: Alarm Object Identier (BER encoded)
Octet n-z: Alarm value (BER encoded)
Most trap interpreters cannot decode this message, which is why varbinds 4 and 5
were added that provide the same information in a more useable format.
This eld provides the varbind of the parameter that is alarming along with the value
of that parameter. This is the same information encoded in varbind #3 Octets 7
through Z.
In the example above the value would be:
OID: 1.3.6.1.4.1.5591.1.4.2.1.27.1.0 (psTamper)
Value: 2 (Open)
This is the information from varbind #3 Octet 5 above. The alarm location will
always be the SCTE-HMS currentAlarmAlarmState and the type will be determined
based on how the alarm was congured in the SCTE-HMS PropertyIdent MIB
tables.
OID 1.3.6.1.4.1.5591.1.1.2.1.2.0 (currentAlarmAlarmState)
Type: 1-7 based on SCTE denitions:
1 NOMINAL
2 HIHI
3 HI
4 LO
5 LOLO
6 Discrete Major
7 Discrete Minor
The Type will be determined by how the alarm is congured in the SCTE-HMS
PropertyIdent MIB, whether it is a Discrete or Analog alarm and the level of alarm
dened for that state.

59704-939-B10-001 Rev. A5 (06/2019)
Page 60
6.0 Data Management, continued
Trap on Normal
The DM3X has the capability of sending a “return to normal” trap once an alarmed condition returns to a normal state.
This feature is enabled by default but can be disabled by setting the TRAP ON NORMAL parameter in the MIB point
atiMgmtSnmpTrapOnNormal to a value of “2”. The contents of this trap message will be identical to the SNMP Alarm
traps, but the value of the Alarm Type dened in the 5th varbind will be “1” (NOMINAL).
SCTE-HMS Warm-Start Trap
In addition to the SNMP alarm traps, the DM3X will also send an SCTE-HMS warm-start trap when it is initialized. Some
SNMP monitoring software requires this trap for auto-identication of the transponder. The format of this trap will be
similar to the alarm trap, but the only information sent will be:
• commonTrapCommunityString, OID 1.3.6.1.4.1.5591.1.3.1.11.0
• commonPhyAddress, OID, 1.3.6.1.4.1.5591.1.3.2.7
• commonLogicalID, OID 1.3.6.1.4.1.5591.1.3.1.1.0
SCTE-HMS Cold-Start Trap
An SNMP-HMS cold-start trap will be generated by the DM3X anytime it initializes with a new rmware version. In
addition, a cold-start trap is sent whenever the conguration has changed. If any parameter in the HMS PROPERTY table
has changed since the last reset, a cold-start trap will be sent upon the next reset.
6.2.3 General Power Supply Alarms
The Intelligent CableUPS detects a wide array of alarms and displays the type of active alarm in the Smart Display screen
and the severity of alarm (e.g., Major/Minor) by means of the Inverter Module LEDs.
General power supply alarms are passed directly from the power supply to the transponder without specic denition
and are classied in the HMS MIB table as psMinorAlarm and psMajorAlarm. There are a number of problems that can
generate these alarms and the exact nature of the situation is not specied. Minor and Major alarms are dened by the
SCTE standards committee as follows:
psMajor
“Service has been dropped or a service interruption is imminent. Indicates that an immediate truck roll is appropriate.”
Several psMajor alarms are latching, meaning that the alarm won’t clear until the problem is xed and after a successful
completion of a Self-Test. A Self-Test is the preferred method of verifying the resolution of the alarm condition as cycling
the power has the potential of masking the problem and not indicating the actual state of the system.
psMinor
“A non-service aecting condition has occurred and should be monitored.”

7.0 Installation
7.1 Verifying Power Supply Device Address
Before installing the hardware, provision the DHCP server with the cable modem’s CM MAC address. This allows the
installation to be veried while the technician is on-site, eliminating the need for a second visit if there are problems with
the installation.
WARNING! ELECTRICAL HAZARD
To reduce the risk of electric shock, completely remove the Inverter Module from the power
supply prior to installation. For eld installation, use a service power supply to avoid losing
power to the load.
CAUTION!
The DM3X Transponder is static sensitive. An ESD wrist strap should be worn when installing the
transponder.
Before removing the Inverter Module, verify the power supply device address and rmware version is correct.
The power supply device address must not be set to zero and no two power supplies monitored by a single DM3X
Transponder can have the same address. The power supply must have a unique address to communicate with a system

7.2 Installation / Replacement Procedure in XM2 Power Supplies
NOTICE:
The DM3X is powered via the Battery A/B Sense/Power Harness. The sense harness must be connected to the
batteries before being plugged into the DM3X A/B connector to power the transponder.
If the XM2 CableUPS has been shipped without a DM3X Transponder, or the existing module requires removal and
replacement, do so via the following procedure:
1. Switch OFF the Inverter Module battery breaker.
NOTICE:
With the battery breaker in the OFF position, the power supply will not go into inverter mode.
2. Disconnect the battery input and temperature sensor cables from the Inverter Module, followed by the tamper, RF
and battery sense cables if a transponder is currently installed.
3. Loosen the Inverter Module thumbscrew and (if applicable) the two transponder thumbscrews.
4. Slide the Inverter Module out of the power supply.
5. Disconnect the ribbon cable attached at the back of the Inverter Module.
6. If the Inverter Module is equipped with a transponder, remove it by loosening the two Phillips captive screws.

7.6 I/O Connections (TPR, ENV)
The Alpha DM3X Transponders are all populated with a Tamper interface to report the status of the power supply
enclosure door when equipped with the optional tamper switch. The Alpha DM3X Transponders are populated with
the Environmental and I/O Controller interface (referred to in this section as I/O Port) which can be used to monitor
and control an array of contact relay devices such as battery heater mats, enclosure moisture sensors and emergency
generators.
The tamper switch interface is designed to report and alarm the status of the power supply enclosure door. The circuit
created by the tamper switch is a contact relay, so other contact relay devices can be designed to be monitored through
this interface. For example, the Alpha Utility Line Sensor (Alpha P/N 746-399-2X) uses the tamper interface to monitor the
Utility outlet to report the presence of line voltage.

9.3.1 Detailed LED Descriptions
After power is applied or a reset occurs, all LEDs will ash in certain patterns indicating the cable modem chipset is
starting or restarting. Once it is ready, it will begin the DOCSIS requirement of searching for the downstream frequency
lock and the LEDs will follow the detailed descriptions below.
ALM/RDY - Alarm/Ready
During normal operation, this LED blinks GREEN, indicating a heartbeat pulse from the processor. The frequency of
ashing by this LED provides a visual alert for power supply discrete major and minor alarms, if congured in the property
and discrete property tables of the SCTE-HMS MIB. The ALM LED (RED) is factory defaulted OFF. Refer to Section
6.2.3, General Power Supply Alarms for information on conguring the DM3X Transponder for active monitoring and
alarming. If an event triggers an HMS alarm, the ALM/RDY LED blinks RED according to the alarm type until the alarm
has been resolved. For a minor alarm, the frequency of ashing (RED) will be more OFF than ON and for a major alarm
the frequency of ashing will be (RED) more ON than OFF. If there are multiple active alarms, including one or more major
alarms with one or more minor alarms, the major alarm will take precedence in terms of the indication.
DS - Downstream Communication
This LED indicates the state of the CM’s attempt to gain a downstream signal. This process may take several seconds,
depending on how long it takes the CM to locate a carrier signal and lock onto a channel. The LED ashes while
searching for the downstream DOCSIS channel and is on solid when the downstream channel is locked.
US - CM Registration
Once a downstream channel has been negotiated between the CM and CMTS, the modem attempts to register with the
DHCP server and obtain the Conguration File. This LED ashes while the process takes place. Once a ranging status of
‘success’ has been received, the LED will remain on solid. This is the best indication that the DM3.0 Series Transponder is
communicating with the CMTS in the headend.
OL - Network Communication Status
The Ethernet link LED remains ON when there is an active connection on the Ethernet port (e.g., a computer is connected
for local diagnostics). Momentary ashes during CPE communications via the Ethernet Craft Port when connected to a
CPE device OR ashes while performing early authentication, IP connectivity, BPI initialization.
LNK - CPE Activity
The CPE activity LED ashes to indicate that data is being transmitted or received between the DM3.0 Series
Transponder and a network device.

9.5 Dual IP Mode
9.5.1 Overview
The DM3X Transponder can operate in either Single (default) or Dual IP mode. In Single IP mode, data from both the
cable modem and power supply are accessed and managed through the modem’s IP address on the secure private
modem network. In Dual IP mode, the Communications Module acts like a CPE device to the cable modem and registers
a second IP address on the public CPE network.
The following table lists some of the common characteristics of the DM3X Single IP and Dual IP congurations:
Single IP Mode vs. Dual IP Mode
Single IPDual IP
Network
Data Access
Security
IP Addresses
Data Management
All data from both the cable modem and
power supply are accessed and managed
through the modem’s IP address on the
secure private modem network.
The Network Management System requires
access to the same private modem network.
Communication with the Communications
Module is limited to the private LAN network
and is very secure.
Where the IP address pool is limited, there is
no need to issue the Communications Module
a CPE IP address. Only one (1) IP Address is
required for the cable modem of the DM3.
Access to the Communications Module is
limited to the private LAN network making
data management less versatile, especially for
eld personnel.
The Communications Module acts like a CPE
device to the cable modem and registers a
second IP address on the public CPE network.
Dual IP mode allows the power supply data
to be accessed and managed from anywhere
within the public (CPE) network.
Since the Communications Module is a CPE
on the public network, access may be less
secure.
The CPE requires its own IP address, which
may be in short supply. A total of two (2) IP
addresses are required, one for the cable
modem and one for the Communications
Module.
The Communications Module is accessible
on the public (CPE) network. This makes data
management more versatile for eld personnel.
Table 9-3, Single IP Mode vs. Dual IP Mode

9.5.3 Conguring Dual IP Mode
To switch the DM3X Transponder from Single to Dual IP mode the atiMgmtSnmpSnmpCPEAccess parameter of the Alpha
MIB will need to be enabled. The Dual IP enable setting can be set through the DOCSIS Conguration File, the DM3.0
Setup File (atidoc33.cfg), the Provisioning Mode via the Communications Web page or remotely using SNMP by setting
the following Alpha MIB:
The CPE Communications Module IP can be assigned its IP, Subnet Mask and Gateway Addresses either via DHCP
(default) or manually, either through the web page or via the below SNMP settings:
NOTICE:
After conguring the Static settings, the Communications Module must be reset in order for the settings to take
eect.
When the IP address
is static, this is the IP
address to which the
CPE will respond.

atidoc33.cfg in Dual IP Mode
NOTICE:
Refer to Section 3.3.5 for details on using the atidoc33.cfg le to propagate custom settings to eld deployed
DM3X Series Transponders.
In Dual IP mode, the DM3X Transponder will rst attempt to download the proprietary conguration le atidoc33.cfg
through the CPE’s interface from a TFTP server on the CPE network. In many networks, the TFTP server is blocked or
disabled, so the DM3X Transponder also has provisions to download this le through the Cable Modem interface from the
modem’s provisioning server if necessary. The lename and TFTP server location may also be specied through special
tags in the DHCP Oer, refer to Section 9.5.3, Specifying atidoc33.cfg Name and Location via DHCP Tags for details.
Similar to Single IP mode, any DM3X Transponder proprietary SNMP MIB setting may be placed in the modem’s DOCSIS
conguration le which would eliminate the need for atidoc33.cfg.
Changing Default atidoc33.cfg Download Settings in Dual IP Mode
The following table explains the download options available for the atidoc33.cfg le in Dual IP mode. The ‘Download

Value: =atidoc33.cfg (an equal sign needs to be in front of the lename for the DHCP server to recognize this as a valid
entry)
9.5.4 Dual IP SNMP Community Strings
The Communications Module community strings used for the CPE Communications Module in Dual IP mode can be
congured by the operator. The default Communications Module read-only community string is AlphaGet. The default
read-write community string is AlphaSet. These settings can be congured with the DOCSIS Conguration File, the DM3.0
Setup File (aitdoc33.cfg) or remotely using SNMP by including the parameters below:
NOTICE:
These community strings are only applicable for CPE access in Dual IP mode. CM access in both Single
IP and Dual IP modes use standard DOCSIS community strings set through the modem conguration le’s
docsDevNmAccessTable. See Sections 3.3.1 and 3.3.2.

9.5.5 Security in Dual IP Mode
In Dual IP mode, additional SNMP security to the DM3X Transponder proprietary MIBs is required since the
Communications Module and power supply data is exposed on the CPE network, which may be more vulnerable to packet
sning and community string deciphering than on the secure cable modem network.
There are two methods of providing SNMP Security in Dual IP mode: the Data Access Key (default), and the Secure
Access List.
Method 1: Dual IP Security Using the Data Access Key
In Dual IP mode atiMgmtSnmpAlphaSetAccess is the only SNMP parameter within the Alpha proprietary MIB
with SNMP write access on the CPE network by default. When this parameter is set to the value of the parameter
atiMgmtSnmpAlphaSetKey, the data access key, SNMP read/write access is granted to all parameters in the Alpha MIB
tree with read/write attributes. When this access is granted, the value of atiMgmtSnmpCPESetEnabled is automatically
changed to “2” (enabled). After the operator is nished setting the SNMP variables, SNMP write access can be disabled
by setting the atiMgmtSnmpCPESetEnabled to “1” or by setting atiMgmtSnmpAlphaSetAccess to any value other than the
data access key or by performing a reset to the DM3X Transponder.
The data access key parameters can be changed from the default values through the DOCSIS Conguration File, the
DM3.0 Setup File (atidoc33.cfg) or remotely using SNMP by including the following Alpha MIB parameters:
Data Access Key Parameters
MIB ParameterObject IDDescriptionValue
atiMgmtSnmpAlphaSetAccess1.3.6.1.4.1.926.1.3.1.3.3.0 Set to Access Key
atiMgmtSnmpAlphaSetKey1.3.6.1.4.1.926.1.3.1.3.4.0 Data Access Key (Dual IP)CIBSET (default)
Corresponds to whether
or not the action taken on
atiMgmtSnmpAlphaSetKey
was successful. Once
enabled, writing 1 to this
variable will disable CPE
sets.
Set to match the value of
atiMgmtSnmpAlphaSetKey
1 = Disabled (False)
2 = Enabled (True)

Page 96
9.0 Start Up and Verication, continued
Method 2: Dual IP Security Using the Secure Access List
The DM3X Transponder provides an alternative method of providing additional SNMP security in Dual IP by limiting
access to the Communications Module’s CPE address. The Secure Access List method limits remote SNMP access to
four IP addresses. Only the IP addresses listed in the SNMP Access Table are able to read or write to the Alpha MIB
parameters from the public (CPE) network. This method overrides the default Data Access Key method.
The IP address entries in the SNMP Access Table can be set through the DOCSIS Conguration File, the DM3.0 Setup
File (atidoc33.cfg) or remotely using SNMP by including the following Alpha MIB parameters:
