• 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 conguration 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 Conguration File.
8
• The DOCSIS Conguration 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 conguration 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.

2.0 Overview, continued

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 congured 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 di󰀨erent security methods to ensure network integrity, but common considerations are:
• Network MAC ltering may have to be modied 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 di󰀨erent than the DHCP server, the response from the DHCP server must contain the TFTP and TOD addresses.
2.3 System Conguration 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 Conguration File per RFC 4639 (IPv4), or through SNMPv3 Notication 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, conguring the network prior to eld installation will allow the installation to be veried while personnel are still on-site. Performing eld installation before network conguration and before the installation can be veried, 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 conguration 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 Conguration File to set modem communication options. (See Section 3.3, The DOCSIS Conguration File for instructions on how to create a DOCSIS Conguration 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.

3.0 Network Conguration, continued

3.2 Establishing IP Connectivity

The DM3X Transponder supports the CableLabs DOCSIS 3.0 IPv6 implementation. The main benet 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 congurable 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 Conguration File
A cable modem’s DOCSIS Conguration File is a type-length-value (TLV) le that contains important operational parameters as dened by the DOCSIS standards. It provides certain settings for the cable modem. In addition to standard entries, settings in the DOCSIS Conguration File should include the modem’s community strings and if an upgrade is necessary, rmware upgrade parameters. Place the Conguration File in the TFTP root directory.
The transponder’s cable modem interface can support both IPv4 and IPv6 addressing schemes. The required DOCSIS Conguration File operational parameters will di󰀨er depending on company policies, cable modem rmware versions and IP addressing schemes. The following DOCSIS Conguration File details listed in this manual are general guidelines. Please consult the published DOCSIS Specication resources (CableLabs) for additional DOCSIS Conguration File details and guidelines.
To build a DOCSIS Conguration File, use a DOCSIS TLV editor program. See the example Conguration Files in Sections 3.3.5 and 3.3.6.
NOTICE:
The modem community strings should be set in the DOCSIS Conguration File. Failure to set community strings will result in a less secure system. For automatically updating modem rmware with the DOCSIS Conguration File, see Section 5.1, Upgrading DM3X Modem Firmware.

NOTICE:
DOCSIS conguration 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 conguration 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 di󰀨erence 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.
20 704-939-B10-001 Rev. A5 (06/2019)
3.0 Network Conguration, continued
3.3.7 Proprietary Conguration File ‘atidoc33.cfg’
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 conguration le is optional and provides an alternative method to the modem’s DOCSIS conguration 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 conguration le.
NOTICE:
The recommended method for setting the SNMP trap address(es) is through the modem DOCSIS conguration le (See Section 3.3, The DOCSIS Conguration File). Alpha-proprietary parameters may also be set through the modem’s DOCSIS conguration le, eliminating the need for the atidoc33.cfg proprietary conguration 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 conguration Setup le must be named “atidoc33.cfg” and placed in the root directory of the TFTP server. DM3X settings are updated according to values dened in this le at start up and after every 24 hours of operation. Sample atidoc33.cfg Entries:
• Network Access Control (3) [Len - 1]: 1
• SNMP MIB Object (11) [Len = 24]: atiMgmtSnmpTrapAddress.1 / 10.20.30.40
• SNMP MIB Object (11) [Len = 24]: atiMgmtSnmpTrapAddress.2 / 10.20.30.50
• SNMP MIB Object (11) [Len = 23]: atiMgmtSysTamperPolarity.0 / 1
