9745-419-B0-001 Rev. A (11/2013)

The EDH4 transponder:

• Uses existing headend equipment

• Uses ANSI/SCTE HMS standards

• Measures analog or receives digital SCTE/HMS data from power supplies

• Can be network-managed through your existing CMTS

To the cable network infrastructure, the EDH4 transponder appears as a DOCSIS 2.0 cable modem. The

EDH4 is assigned an IP address like any other DOCSIS device on the DOCSIS network. The assigned

IP address is used to access the HMS status monitoring data via SNMP, the HMS MIBs and a Web

interface.

For complete DOCSIS specications, please visit the CableLabs Website (www.cablelabs.com).

Fig. 1-1, The EDH4 Transponder

1.0 Introduction

1.1 Overview

Alpha’s EDH4 transponder provides the ability to manage network power through an existing cable

modem infrastructure for a variety of power supplies. Please see your Alpha representative for a complete

listing. This manual focuses on the power supplies listed below.

HMS-Enabled Power Supplies:

• XM2 with EDSM Interface

Non-HMS Alpha Power Supplies:

• AM with RPM interface

• XM with USM interface

• XM2 with USM2 or USM2.5 interface

Lectro Power Supplies:

• ZTT

• ZTT+

• CPR with Level 2 Interface

A single transponder can monitor a power supply and a maximum of four (4) battery strings. Power sites

with multiple standby power supplies and generators may possibly be monitored with one EDH4 unit

depending on the architecture, power supply models and data interfaces, please contact your Alpha

representative for details. The EDH4 transponder transmits data to a management system over the

network’s existing DOCSIS infrastructure using standard SNMP (Simple Network Management Protocol).

Status monitoring information is compatible with ANSI/SCTE HMS standards.

1.0 Introduction, continued

1.2 Interfaces

The EDH4 includes six status LEDs and a mix of analog and digital connections supporting multiple

congurations.

Fig. 1-2, The EDH4 Transponder Interfaces

1.3 Receiving Data

The EDH4 transponder can receive analog power supply data through its PWR SUPPLY port and battery

data through its two battery ports (BAT A/B and BAT C/D). It can receive HMS power supply data through

its HMS interface port (rear panel) and can simultaneously directly measure and report battery voltages

through its two battery ports (BAT A/B and BAT C/D). The transponder uses the direct battery connection

when congured to receive battery data through both the HMS interface port and a direct battery

connection.

1.4 Powering the EDH4 Transponder

Power the EDH4 transponder through one of the following transponder interfaces:

• Battery Interface Connection (BAT A/B)

• Battery Interface Connection (BAT C/D)

• HMS interface port (HMS)

• Auxiliary (generic) I/O (AUX I/O)

In the event of multiple sources of power (e.g., batteries and HMS port), the highest voltage will source

power to the transponder.

Installation Notes:

• Before eld installation, the transponder’s MAC address should be loaded into the DHCP server,

and DOCSIS conguration le options should be set. This permits on-site verication of network

connectivity and data, preventing the need for an additional visit to the site should there be a problem

with the installation.

• Do not place the transponder on top of the power supply or batteries.

• Make all battery harness connections and connect the interface cable to the power supply before

connecting the cables to the transponder.

1.5 Connector & LED Summary

1.0 Introduction, continued

Connector Description

RF The RF connector, the physical interface to the cable plant, exchanges RF data between the CMTS

and the transponder.

BAT A/B and BAT C/D There are two battery interface connectors to the battery strings. The connection labeled BAT A/B

interfaces to battery strings A and B. The connection labeled BAT C/D interfaces to battery strings

C and D. The EDH4 also receives power through these interfaces when they are used to measure

battery data. When the transponder is used to monitor an SCTE HMS power supply, battery data

can be gathered through the transponder's SCTE HMS connection (labeled HMS), or through the

BAT A/B and BAT C/D ports.

AUX I/O The AUX I/O connector provides a generic input/output port to allow monitoring of co-located

equipment if required. Pin 19 allows powering the unit with 24 - 60 Vdc. Also, 3.3 volt power is

available on pin 20. Common ground is on pin 1.

HMS The HMS connector on the back of the transponder accepts the standard SCTE HMS-022 Interface

Cable, and exchanges ANSI/SCTE HMS digital data between the transponder and a power supply

with a SCTE HMS-022 interface.

PWR SUPPLY The main power supply interface is through this connector. This connector delivers both digital and

analog signals to the transponder for monitoring as well as digital outputs and an interface to an

external temperature sensor and/or line voltage sense transformer, if applicable.

CNTL CNTL provides connection to a battery mat heater control.

LED Indicators

The EDH4 transponder includes six green LEDs:

• STAT • US

• ELINK • DS

• ONLINE • PWR

The LEDs indicate transponder status. See Section 3.1 Checking the LEDs.

Table 1-1, EDH4 Connector Functionality

745-419-B0-001 Rev. A (11/2013)

PS

Cable modem infrastructures are likely to have unique characteristics. Therefore it is strongly

recommended one transponder be installed and tested for proper operation before deploying the entire

system throughout your network.

Installing the transponders and making them operational consists of the following steps, which are

explained in detail in this manual.

• Provisioning the transponders in the network

• Adding conguration data to the cable modem conguration le

• Installing the transponder

• Powering the transponder and checking the LEDs for status

• Verifying the power supply parameters are reporting correctly on the transponder Web page and/

or power supply monitoring system.

1.6 Provisioning the Transponders in the Network

Before installing EDH4 transponders, the transponders must be provisioned in the network for the

network to recognize, discover, and communicate with them when they are powered up. The following

graphic shows a typical network.

NOTE: Some provisioning systems require that the transponder’s MAC address be added to the CMTS

prior to installing the transponder to achieve full functionality.

1.8 Security

Different security methods are used to ensure network integrity. Some common issues are:

• A subscriber account (where the transponder is the subscriber) may be required for each

transponder

• The transponder’s MAC address may have to be pre-loaded into the CMTS

• MAC ltering may have to be modied to allow MAC addresses starting with 00:10:3F:xx:xx:xx or

00:26:97:xx:xx:xx to be registered

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

• Firewalls must allow communications between the cable modem and the various servers.

1.9 CongurationFileChoices

Alpha strongly recommends that the cable modem conguration le has been successfully modied and

tested prior to deploying transponders into the system in quantity. The transponder manages SNMP lters

and trap destinations via the docsDevNmAccessTable.

To ensure the proper management of SNMP access, such as limiting access to specic SNMP managers

or allowing the transponder to send SNMP/HMS traps, the docsDevNmAccessTable must be populated

via the cable modem conguration le.

Additional SNMP Object Identiers (OIDs) may be added to further congure other options such as the

transponder's HTTP port, its User Name and Password conguration information.

For Dual IP conguration, refer to Section6.0,DualIPConguration.

The deployment of an EDH4 DOCSIS-based transponder is similar to provisioning a standard subscriber

cable modem or Multimedia Terminal Adapter (MTA) with certain exceptions owing to the transponder

being a system support device. For instance, care must be used when provisioning, such that it is not

invoiced in the billing system or mistakenly blocked. Cable operators will want to adapt a deployment

strategy to t their unique operational landscape.

2.1 Alpha XM Series 2 and EDSM Card (HMS-Enabled)

The EDH4 transponder can be interfaced to power supplies that support the SCTE-HMS interface. In

addition, the EDH4 transponder can receive battery string data through the HMS interface port and can

measure battery strings directly. If battery data is present from both the HMS interface and the direct

battery connection (EDH4 BAT A/B or BAT C/D), the EDH4 transponder uses the direct battery connection

data.

2.0 Installation

When installing the EDH4 transponder (which is recognizable by the presence of 6 LEDs on the

front panel, as opposed to 4 on the older models), care must be taken to recognize the difference

between the new labeling of the 4 pin front panel connector “CNTL.” This is to be used with

a battery mat heater control. The older units had an identical connector, labeled “AUX PWR.”

DAMAGE WILL RESULT if the older cable is plugged into the new transponder.

Alpha’s Enhanced Digital Status Module (EDSM) is a status monitoring interface for the XM Series

2 power supply. The EDSM continuously gathers power supply, generator, and battery data. Data is

transferred to an industry standard digital transponder (DT) using a serial interface, specied by the ANSI/

SCTE25-3 standard. DT connector equipped EDSMs connect to either an embedded digital transponder

or an external digital transponder such as the EDH4.

2.2 Alpha XM Series 2 Power Supply and USM Series Interface

The XM2 batteries are isolated from chassis ground by design. Any voltage potential difference

between battery (-) and chassis ground must be eliminated before installing the transponder

to avoid potential transponder damage. To accomplish this, attach a ground jumper between

battery (-) and chassis ground before installing the transponder. Once the transponder is

installed the jumper may be removed if desired.

Switch Battery Breaker OFF prior to removing the Inverter Module for USM2/USM2.5 Card

installation and conguration.

Installation Procedure:

1. Remove the XM2 Inverter Module:

• Switch OFF the battery breaker. Disconnect the battery input, and the temp probe cables.

• Disconnect all the cables (TMPR, XPDR, and SYS COM) from the Communications Module.

• Loosen the thumbscrews on the Inverter Module.

• To remove the Inverter Module, grasp ONLY the handle of the Inverter Module, and pull rmly to

release the module from the connector. Slide the module assembly straight out.

• Disconnect the ribbon cable attaching the Inverter Module to the power distribution board before

sliding the inverter module all of the way out.

2. Plug the 2 x 9 pin strip connector into the Inverter Module.

3. A new USM2.5 will come with a snap-on support. Position the USM2.5 over the strip connector and

the rear hole for the support and carefully push into place. Verify the position of the strip connector,

and that the support is fully seated into the Inverter Module mounting shield.

4. When replacing a USM2.5 the support may already be installed. If so, align the USM2.5 over the

supports and gently push onto the strip connector. Verify the position of the strip connector, and that

the support is fully seated into the Inverter Module mounting shield.
