2.0 System Overview

2.1 System Diagram

All power supply, battery, and generator data are stored in the class information base (CIB) tables in

the power supply. These data are accessible directly via the power supply’s smart display (see the

power supply’s technical manual for details). The CIB tables are the source of the transponder’s data.

The XP-DSM is comprised of a cable modem and a transponder. The transponder contains both

SCTE-HMS management Information base (MIBs) and the propriety 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 6.1). The Alpha MIB contains all the data of the SCTE-HMS MIBs plus

additional power supply settings and values, and transponder data.

Power supply and transponder parameters can be monitored and set locally using a personal

computer and a Local Port Adapter (Alpha P/N 745-826-21) (see Section 4.0).

The XP-DSM transmits data via its cable modem directly over the Coax or Hybrid ber-coax network.

The Cable Modem Termination System (CMTS) is the bridge between the cable network and the

TCP/IP network. The XP-DSM’s cable modem communicates directly with the CMTS.

The following ports of the Transmission Control Protocol/Internet Protocol network must be opened:

161 = SNMP 162 = SNMP Traps 69 = TFTP 80 = HTTP

The Dynamic Host Conguration (DHCP) server needs to be provisioned with the XP-DSM’s cable

modem RF MAC Address: the MAC Address needs to be assigned a DOCSIS Conguration File (see

Section 3.1).

The DOCSIS Conguration File should be saved in the TFTP Root Directory of the Trivial File

Transfer Protocol (TFTP) Server. If used, a DSM Setup File should be placed in the same location. To

build DOCSIS Conguration or DSM Setup Files, see Section 3.0.

The Time of Day (TOD) Server provides the cable modem with the current date and time.

A Network Management System (NMS) or MIB Browser allows remote monitoring of parameter

values and changing of settings in MIB tables. SCTE-HMS and Alpha MIBs must be installed in the

browser (Section 6.0). Alarms and traps can be set and monitored (see Section 6.3).

In both Single and Dual IP Modes, power supply parameters can be monitored on an internal network

Web browser. In Dual IP Mode only, the transponder is given an IP address independent of the cable

modem and parameters can be monitored on the public network (see Section 2.2).

Fig. 2-1, Single IP Mode

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. The

transponder is not accessible from the public

(Customer Premises Equipment) network.

Consequently, the Network Management

System (NMS) that monitors the power supplies

must have access to the same private modem

network.

Single IP Mode Considerations:

• Communication with the transponder 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 transponder a

CPE IP address.

• Access to the transponder is limited to the private LAN network making data

management less versatile, especially for eld personnel.

Dual IP Mode

In Dual IP Mode the transponder acts like

a CPE device to the cable modem, and

registers a second IP address on the public

CPE network. This allows the power supply

data to be accessed and managed from

anywhere within the public (CPE) network.

Dual IP Mode Considerations:

• The transponder is accessible on

the public (CPE) network. This

makes data management more

versatile.

• Because the transponder is a CPE on the public network, access is less secure.

• The CPE requires its own IP address, which may be in short supply.

NOTE:

The transponder settings determine whether the system operates in Dual or Single IP Mode. The cable

modem always interacts with the transponder both as a CPE and as an extension of its own IP address.

Fig. 2-2, Dual IP Mode

11745-814-B0-001, Rev. A

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:

• MAC ltering may have to be modied to allow RF MAC registration of addresses starting

with 00.05:CA and 00:03:08.

• For SNMP access, UDP ports 161 & 162 must not be blocked.

• For TFTP access, port 69 must not be blocked.

• For HTTP access, port 80 must not be blocked.

• For Web access with rmware version 1.05.0, allow trafc on port 61520.

• Firewalls must allow communication between the cable modem and the TFTP, DHCP,

SNMP, and TOD servers.

• If the address of the TFTP or TOD server is different than the DHCP server, the response

from the DHCP server must contain the TFTP and TOD addresses.

2.0 System Overview, continued

2.4 SystemCongurationandInstallationOverview

NOTE:

Before installation read all of the “System Overview” Sections.

XP-DSM installation and setup is comprised of three basic steps:

1. Conguring the Network: provisioning the DHCP Server with the transponder’s MAC

Address (Section 3.1) and assigning it a DOCSIS Conguration File (Section 3.2).

2. Setting Options: There are a number of ways transponder options can be set.

They can be set automatically before or after hardware installation via the DOCSIS

Conguration File or the DSM Setup File (see Sections 3.2 and 3.4), remotely after

installation of the hardware (Section 3.3), or locally by plugging a computer directly

into the transponder’s local port (Section 4.0). The SCTE-HMS and Alpha MIBs

need to be compiled into a MIB browser before it can be used to monitor or set

transponder and power supply parameters (Section 6.0).

3. Field Installation: a straight-forward procedure that consists of installing the XP-

DSM into the power supply (Section 7.0), installing the battery sense wire harnesses

(Section 8.0), and verifying operation (Section 9.0).

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 (Section 9.0). Performing eld installation before network conguration—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.

2.5 XP-DSM Start-up and Reboot Routine

The above diagram, read left to right, indicates the order of operations as the transponder comes

online. There are certain conditions that must exist for each step to occur, resulting in successful data

monitoring and management. The numbers below correspond to the numbered arrows above.

When the XP-DSM is installed and powered-up, it nds the DOCSIS frequency being used by the

Cable Modem Termination System (CMTS), and establishes communication.

The CMTS communicates with the DHCP server to get an IP address for the XP-DSM’s cable

modem. The DHCP server must be provisioned with the XP-DSM’s cable modem RF MAC

address for it to recognize the modem as a valid device (Section 3.1). This means the cable

modem’s RF MAC address must be assigned a specic DOCSIS Conguration File, stored in the

TFTP root directory of the TFTP server (Section 3.2).

Once the modem is given an IP address, it is synchronized with the network through the Time of

Day (TOD) Server.

As the modem comes online, the XP-DSM downloads the DOCSIS Conguration le from the

THCP Server, which sets modem options (see Section 3.2).

The XP-DSM transponder’s options are set according to the DSM Setup File (if used). In Dual IP

Mode, the XP-DSM transponder is given its own IP address as a CPE to the modem (see Section

2.2).

Monitoring and Managing Transponder and Power Supply Parameters.

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.

The MIB browser is a valuable networking tool that enables personnel to remotely manage

and congure an individual transponder through the SNMP-HMS and Alpha MIBs. The

SCTE-HMS and Alpha MIBs must be compiled in the MIB browser in order to access all the

power supply and transponder parameters. (see Sections 6.1 and 6.2).

A Web interface enables personnel direct, read-only access to transponder and power supply

parameters using a common Web browser. It may be used to verify installation (see Section

9.3). In the default Single IP Mode, only Web browsers inside the private network have

access. While in Dual IP Mode, power supply data can be monitored on the public network

(see Section 2.2).

Transponder and power supply parameters can be monitored and options set locally using a

laptop or PC with a Local Port Adapter (Alpha P/N 745-826-21) (Section 4.0).

3.0 NetworkConguration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

Conguration File to set modem communication options (see Section 3.2 to create a DOCSIS

Conguration 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) and inherits community string settings from the

DOCSIS Conguration File.

If operating in Dual IP Mode, the DHCP server must also be provisioned with the

transponder’s CPE MAC Address, and extra security is needed (see Section 3.5)

The XP-DSM can be provisioned with static or dynamic IP addresses.

The RF and CPE MAC addresses are located in a number of places on the XP-DSM, and on

the packing slip, see below.

3.2 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 rmware upgrade

parameters. Place the conguration le in the TFTP root directory.

Due to different rmware and manufacturers’ Code Verication Certicate (CVC) les,

separate DOCSIS Conguration Files are required for the two cable modem versions

used with the XP-DSM in order to upgrade modem rmware: If your network includes

both versions, you will need to create two Conguration Files. The cable modem version

is indicated by the Organizationally Unique Identier (OUI) of the cable modem’s RF MAC

Address (see Section 5.1):

00:03:08 AM

00:05:CA Hitron

To build a DOCSIS Conguration File use a DOCSIS TLV editor program.

See the example Conguration File on the next page.

• 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 (default community strings will be required).

• For automatically updating modem rmware with the DOCSIS Conguration File, see Section 5.1.

3.2.1 SettingModemCommunityStringsintheDOCSISCongurationFile

Set the modem community strings with the DOCSIS Conguration File by including in it

the following SNMP parameters:

Table 3-1, Modem Community String Parameters

In Single IP Mode the community strings set in the DOCSIS Conguration File override any community strings

set in the Alpha MIB for the transponder (Section 3.3).

In Dual IP Mode or if the modem is left unsecured, the XP-DSM transponder reverts to default community

strings. Change these strings through the Alpha MIB (Section 6.2), either manually using a MIB browser or

automatically using a DSM Setup File (Section 3.4).

3.4 The DSM Setup File

The DSM Setup File, atidoc01.cfg, is an optional type-length-value (TLV) formatted le

similar to the modem’s DOCSIS Conguration File that distributes custom Alpha MIB settings

to all XP-DSMs on a network. Unlike the DOCSIS Conguration File, the DSM Setup File

is made up only of type 11 entries, OIDs supported by the transponder through the Alpha

MIB. The XP-DSM is programmed to check for this le at startup and after every 24 hours of

operation (congurable) and update with the settings dened.

The IP address of the TFTP server where atidoc01.cfg is located must be dened in the

modem’s DOCSIS Conguration File using the parameter docsDevSwServer. This entry

should be dened as type 21 (Software Upgrade TFTP server) and not type 11 (misc. SNMP

entries).

If a DSM Setup File is not used, the transponder will retain its default settings (see Section

3.3) until they are changed manually with a MIB browser or a local computer connected to the

XP-DSM’s local port (see Sections 6.2, 4.0).

Some common parameters set in the DSM Setup File are:

• Switching to Dual IP Mode.

• Setting transponder community strings in Dual IP Mode, see Section 3.4.3.

• Upgrading transponder rmware, see Section 5.2.

• Disabling or enabling the transponder’s Web server.

• Enable ‘Trap on Normal’, see Section 6.3.

• Setting SNMP trap addresses, see Section 6.3.

• Setting power supply parameters (Alpha recommends contacting your Alpha

representative before changing power supply settings).

3.4.1 Building the DSM Setup File

To build a DSM Setup File, enter SNMP parameters and values from the Alpha MIB

(see Section 6.2) inside a TLV le using a TLV editor.

The entry atiMgmtSysDownloadCfgCheckProgress with the value of 3 is the le

marker that the XP-DSM looks for to begin reading entries and must be the rst entry

in the le.

The DSM Setup File must be named atidoc01.cfg and placed in the root directory of

the TFTP server.

XP-DSM settings are updated according to values dened in this le at startup and

after every 24 hours of operation.

See the example le on the next page.

NOTE:

Most TLV editors will display the parameter name instead of the Object ID if the SNMP MIB le ATI-TABLES-

MGMT-MIB.mib is copied into the installation directory of the TLV editor. This makes the le more readable.

NOTE:

The procedure in this section applies to rmware version 1.08.0 or newer. For an application to upgrade from

earlier rmware versions, go to www.Alpha.com>Broadband>StatusMonitoring>DSM>XP-DSM Downloads.

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 Conguration 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. This can be done with the DSM Setup File by including the

following parameters:
