1.0 Introduction to the DOCSIS Transponder
The DOCSIS Digital Embedded Transponder for the XM2 power supply manages network powering
through existing cable modem or high speed data infrastructure. A single transponder can monitor and
manage multiple power supplies, multiple strings of batteries, and one generator . The transponder
transmits data to a management system via the existing DOCSIS network. SNMP (Simple Network
Management Protocol) keeps bandwidth use to a minimum. S tatus monitoring dat a is compatible with
ANSI/SCTE HMS (Hybrid Management Sublayer) standards.
With optional V oIP test functionality , the power supply transponder becomes a powerful network
diagnostics tool. Contact Alpha Technologies for more information.
Outstanding Features:
• Uses existing headend DOCSIS CMTS equipment.
• Uses ANSI/SCTE HMS st andards.
• Single transponder supports up to six power supplies, two battery strings, and one generator .
• Additional battery strings (up to a total of six) can be monitored with Alpha’s extended MIBs.

2.0 Transponder Installation
Steps to a Successful Installation:
• Operator’s IT Department must allow the transponders’ Cable Modem (CM) to obtain an IP address
from the DHCP Server.
• Operator’s IT Department must load the HMSINIT.ini file on the TFTP Server .
• Operator’s network security policies must allow SNMP traffic to pass between transponder and
SNMP manager .
• Install the transponder and any related equipment in the power supply .
• Connect an RF drop.
• Verify proper operation.
2.1 Provisioning the Transponder
Complete Sections 2.1.1 and 2.1.2 before connecting the transponder to the RF network.
Otherwise, you must reset each transponder.
2.1.1 Network Connectivity
The transponder’s CM must be recognized by the CMTS as a valid device. The CM
must obtain an IP address from the DHCP server, locate the TFTP and T OD servers,
and communicate with the SNMP management server (trap receiver). CMTS and
system vendors use different security methods to insure network integrity , but some
common issues are:
• A “subscriber account” (where the subscriber is the transponder) may be required
for each transponder.
• The transponder’s MAC address may have to be pre-loaded into the CMTS.
• MAC filtering may have to be modified to allow MAC addresses starting with
00:10:3f:xx:xx:xx to be registered.
• For SNMP access, UDP ports 161 & 162 must not be blocked.
• Firewalls must allow communication between the CM and the TFTP, DHCP, SNMP,
and TOD servers.
• If the address of the TFTP and/or TOD server is different than the DHCP server , the
response from the DHCP server must contain the TFTP and TOD addresses.
745-420-C0-002 Rev . B
11
2.0 Transponder Installation, continued
2.1 Provisioning the Transponder, continued
2.1.2 Transponder Configuration File
The transponder’s CM, at first power-up or reset command, requests a configuration file
from the TFTP server . The file must contain the IP address of the SNMP manager. It
may also contain up to five additional SNMP trap recipients. The SNMP manager will
be the only device that can perform SNMP set/get/get-next commands. The trap
recipients and SNMP manager receive the same traps generated by the transponder .
• File type: ASCII text file
• File name: HMSINIT.ini
• File location: Root directory of the TFTP server
• Maximum file size: 4096 bytes (4Kb)
• File format:
// IP address of the SNMP manager
[SERVER IP]
10.1.1.5
// IP address of up to 5 additional trap receivers
[TRAP SERVER IP]
10.1.1.6
10.1.1.7
• The “//” characters indicate an optional comment line.
• The identifiers must be in all caps, and enclosed by brackets “[ ]”.
• The IP addresses must appear on the next line after the identifier , one address per
line. Replace the IP addresses in this example with the actual addresses used in
the network.
• The trap server IP identifier is optional. Addresses for up to five trap recipients can
be listed.

745-420-C0-002 Rev. B
2.0 Transponder Installation, continued
2.2 Verifying Software Version and Device Address
Before removing the Inverter Module (IM), verify the power supply software version and device
address are correct.
• IM firmware v3.00.0 is the minimum version compatible with the DOCSIS Embedded
Transponder .
• The power supply device address must not be set to zero, and no two power supplies
monitored by a single transponder may have the same address.
1. Press the Enter key on the inverter module twice to access the SETUP Menu.
2. Press the Down key until CODE VER is displayed.
3. V erify that the software code is 3.00.0 or higher .
4. Press the Down key twice until DEVICE ADDRESS is displayed.
5. If the address is correct (and not zero), skip to S tep 10.
6. To change the address, press the Enter key to enter the Edit mode.
7. Press the Up or Down key until the desired address (between 1 and 7) is displayed.
Remember that each power supply on a single transponder must have a unique address.
8. Press the Enter key to load the new address.
9. Press the Enter key again to accept the new data.
10. Press ESC three times to return to the OPERATION NORMAL screen.
2.3 Installing the Transponder Hardware
The following installation procedure assumes the EDSM card, AlphaGuard CMM data collection
module and AlphaBus network have already been inst alled. If not, see the EDSM Installation
and T echnical manual (P/N 704-721-C0) for further instructions.
The Embedded Transponder is static sensitive. An ESD wrist strap should be worn when installing
the transponder .
T ools Required: #1 Phillips Screwdriver
1. Move the XM2 Battery Breaker to the OFF position.
2. Unplug all connections to the front of the Inverter Module (battery cable, RTS, etc).
3. Loosen the thumbscrews holding the Inverter Module into the power supply . Slide the
Inverter Module out just enough to disconnect the ribbon cable. Now slide the Inverter
Module out of the power supply .
T o reduce the risk of electric shock, completely remove the Inverter Module from the Power
Supply prior to installation.

2.3 Installing the Transponder Hardware, continued
4. Attach the new transponder ribbon cable supplied to the 10-pin connector on the
transponder as shown in Fig. 2-1. The connectors are keyed to prevent incorrect
orientation.
5. Attach the plastic standoff to the transponder PC board as shown in Fig 2-2.
6. V erify that the MAC address label is installed on the transponder. If the label is missing,
locate the label in the packaging and apply to the transponder as shown in Fig 2-3.
7. Place the transponder as shown in Fig 2-3 below . The RF connector must be inserted
through the front of the Comm Module bracket.
8. Press the standoff into the Inverter Module chassis.
9. Secure the transponder to the Comm Module Bracket with the two screws provided.
10. Connect the transponder ribbon cable to the EDSM. Note the 90o twist in the cable.
1 1. Reconnect the Inverter Module ribbon cable, and reinstall the Inverter Module into the power
supply.
12. Reconnect all the cables unplugged in Step 2 .
13. Move the Battery Breaker to the ON position.

2.5 Verifying Transponder Operation
745-420-C0-002 Rev . B
During initial transponder power-up, the RDY LED will be on solid.
• Once the reset is complete, the RDY LED will flash at a ½ sec ON, ½ sec OFF rate.
• The RX LED will now be ON, flickering OFF occasionally , indicating a link with the CMTS
has been established.
• The HMS LED will occasionally flicker ON, indicating communication with the EDSM.

3.0 Network/Element Management Software
3.1 Provisioning the SNMP Manager
The following MIB (Management Information Base) files are required for the SNMP Manager to
collect data from the transponders. These files can be found on the Society of Cable
T elecommunications (SCTE) web site
so they should be compiled in the following order listed below:
ANSI/SCTE 36 2002 (formerly HMS 028), SCTE-ROOT Management Information Base (MIB)
Definitions
ANSI/SCTE 37 2003 (formerly HMS 072), Hybrid Fiber/Coax Outside Plant S tatus Monitoring

www .scte.org. These are dependencies between MIB files
3.2 Transponder Acquisition by the SNMP Manager
The transponder must first complete its initialization/registration and retrieve the .ini file from
the TFTP server . The transponder will then send a warm-start trap to the SNMP Manager
(specified as the Server IP in the .ini file). This trap provides the SNMP Manager with the
MAC and IP addresses of the transponder and should, depending on the configuration of the
manager software, initiate monitoring of the power supply system.
16
745-420-C0-002 Rev. B
4.0 Local Port
The local port allows the technician to communicate with the transponder and power supply through a
PC’s RS-232C serial port.
1. Connect the optional Local Port to RS-232C Adaptor Cable (Alpha P/N 875-349-10) between the
transponder’s Local Port and the computer’s serial port. Launch the computer’s Terminal Emulation
Software (HyperT erminal is recommended).
