1.0 Introduction The AlphaNet DSM Series Embedded DOCSIS Transponder (XP-DSM) allows monitoring of Alpha XM2 and GMX power supplies through existing cable network infrastructure. Advanced networking services provide quick reporting and access to critical powering information. The XP-DSM utilizes Simple Network Management Protocol (SNMP) and standard Management Information Bases (MIBs) to provide network status monitoring and diagnostics.

2.0 System Overview, continued 2.2 Single IP Mode vs. Dual IP Mode Overview The XP-DSM can operate in either Single (default) or Dual IP Mode. To switch the transponder from Single to Dual IP Mode the “Block CPE” function must be disabled in the Discrete Menu of the Alpha MIB (see Section 6.2). Single IP Mode In Single IP Mode 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.
2.0 System Overview, continued 2.3 Network Connectivity Overview The XP-DSM cable modem must be recognized by the CMTS as a valid device to be assigned an IP address from the DHCP server, locate the TFTP and TOD servers, and communicate with the SNMP management server (trap receiver) (see Section 2.5). CMTS and system vendors use different security methods to insure network integrity, but common considerations are: 2.

2.0 System Overview, continued 2.5 6 XP-DSM Start-up and Reboot Routine, continued Monitoring and Managing Transponder and Power Supply Parameters. 6a A network management system (NMS) is software used to monitor transponder and power supply parameters on the network. The XP-DSM operates with an any NMS that supports SCTE-HMS standards. 6b The MIB browser is a valuable networking tool that enables personnel to remotely manage and configure an individual transponder through the SNMP-HMS and Alpha MIBs.
3.0 Network Configuration and Option Settings 3.1 Provisioning the DHCP Server with the MAC Addresses In the DHCP server, assign the cable modem’s RF MAC Address with a DOCSIS Configuration File to set modem communication options (see Section 3.2 to create a DOCSIS Configuration File). If desired, the MAC Address can be assigned a DSM Setup File to set transponder options (see Section 3.4). In Single IP Mode, if a DSM Setup File is not assigned, the transponder runs on its default settings (see Section 3.
3.0 Network Configuration, continued 3.2 The DOCSIS Configuration File A cable modem’s DOCSIS Configuration File is a type-length-value (TLV) file that contains important operational parameters as defined by the DOCSIS standards. It provides certain settings for the cable modem. In addition to standard entries, settings in the DOCSIS Configuration File should include the modem’s community strings and firmware upgrade parameters. Place the configuration file in the TFTP root directory.

3.0 Network Configuration, continued 3.3 Setting Communication Options The XP-DSM ships with the following default communication option settings: • Access Mode – Single IP • Network registration – DHCP • HTTP Web Server – Enabled • Read Community String – AlphaGet • Read/Write Community String – AlphaSet Communications Settings may be changed through the Alpha MIB remotely using a SNMP MIB browser, automatically using a DSM Setup File (see Section 3.
3.0 Network Configuration, continued 3.4 The DSM Setup File The DSM Setup File, atidoc01.cfg, is an optional type-length-value (TLV) formatted file similar to the modem’s DOCSIS Configuration File that distributes custom Alpha MIB settings to all XP-DSMs on a network. Unlike the DOCSIS Configuration File, the DSM Setup File is made up only of type 11 entries, OIDs supported by the transponder through the Alpha MIB.
3.0 Network Configuration, continued 3.4 The DSM Setup File, continued 3.4.2 Example of an atidoc01.cfg DSM Setup File Below is an example DSM Setup File with the following settings: Example DSM Setup File Parameters and Values Parameter Type Description Value atiMgmtSysDownloadCfgCheckProgress Integer OID: 1.3.6.1.4.1.926.1.3.2.1.12.0 Required file marker entry 3 atiMgntSnmpTrapAddress1 OID: 1.3.6.1.4.1.926.1.3.1.1. IP address Optional SNMP trap destination address 10.80.0.
3.0 Network Configuration, continued 3.4 The DSM Setup File, continued 3.4.3 Setting Transponder Community Strings with the DSM Setup File The default transponder read-only community string is AlphaGet. The default read-write community string is AlphaSet. These community strings are overridden by modem community strings set in the DOCSIS Configuration File. If the modem is left unsecured or if operating in Dual IP Mode, the XP-DSM needs to have its community strings set in the Alpha MIB.
3.0 Network Configuration, continued 3.5 Security in Dual IP Mode In Dual IP Mode additional SNMP security is required because data is exposed on the CPE network, which is more vulnerable to packet sniffing and community string deciphering than on the secure cable modem network. For an explanation of Dual IP Mode, see Section 2.2. For an explanation of the Alpha MIB, see Section 6.2. There are two methods of providing SNMP Security in Dual-IP Mode: the Secure Access List, and the Key-Match.
4.0 Using the Local Port The local port allows a technician to monitor and set XP-DSM parameter values directly using a personal computer and a Local Port Adapter Cable (Alpha Alpha P/N 745-826-21). Terminal emulation software is necessary (HyperTerminal is recommended). Procedure: 1. Launch the terminal emulation software.

6.0 Data Management The XP-DSM remotely reports power supply data and alarms using the Simple Network Management Protocol (SNMP) over the DOCSIS (Data Over Cable Service Interface Specification) communication specification. The XP-DSM 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).
6.0 Data Management, continued 6.1 The SCTE-HMS MIB The SCTE-HMS MIB can be monitored with a SNMP compatible Network Management System (NMS) or with a MIB browser. The following MIB files are required for the MIB browser to collect data from the transponder. These files can be found on the Society of Cable Telecommunications (SCTE) Web site: www.scte.org. There are dependencies between MIB files, so they should be compiled in the following order.

There are a number of problems that can generate these alarms, and the exact nature of the situation is not specified.
7.0 Hardware Installation Before installing the hardware, provision the DHCP server with the cable modem’s RF MAC Address (see Section 3.1). If operating in Dual IP Mode, provision it with the CPE MAC Address as well. This allows the installation to be verified while the technician is on-site, eliminating the need for a second visit if there are problems with the installation. WARNING! To reduce the risk of electric shock, completely remove the inverter module from the power supply prior to installation.
7.0 Hardware Installation, continued 7.2 Hardware Installation Procedure NOTE: With the battery breaker in the OFF position, the power supply will not go into inverter mode. 1. Switch OFF the power supply’s battery breaker. 2. Unplug all inverter module connections (e.g. battery cable, remote temperature sensor). 3.

11.0 Frequently Asked Questions How is power supply data accessed from the XP-DSM? The XP-DSM uses Simple Network Management Protocol (SNMP) to provide power supply data and access to the transponder settings through the network. Management Information Base (MIB) files must be compiled into the SNMP software to provide a map of the data and settings. See Section 6.0. The Society of Cable Television Engineers (SCTE) created a standard for monitoring power supply data.
11.0 Frequently Asked Questions, continued Local Port: At the command prompt type TEXT. The firmware version will be displayed next to the SysDescr variable and will disaply as ‘ATI P01V1.10.0’ indicating firmware version 1.10.0. SNMP: SCTE-HMS CommonVendorInfo: OID: 1.3.6.1.4.1.5591.1.3.1.5. See Section 5.0. What is the purpose of the DOCSIS Configuration File? A DOCSIS Configuration File is required for all DOCSIS cable modems and provides settings for the cable modem.
11.0 Frequently Asked Questions, continued What if SNMP data can be accessed from the cable modem but power supply data is unavailable in Single IP Mode? Remotely verify that power supply data can be viewed through a Web browser. If you can connect to the Web page but cannot see power supply data, the problem is most likely one of the following: • The DEVICE ADDRESS on the power supply is set to ‘0’. The DEVICE Address must be set to a non-zero value. See Section 7.1.
