The Motorola Modular Processing System (MPS) is a complete line of modular headend support products that combine the functions of separate headend equipment into a single versatile chassis.

The MPS family supports signal reception, processing, transmission, and access security. The modular approach supports:

� System expansion flexibility through the addition or exchange of functional modules that meet system upgrade requirements

� Cost efficient sparing through inventory of spare functional units rather than complete MPS units

� Reception and transmission of multiple transport streams

� Processing of MPEG-2-compatible transport streams

Each MPS consists of a chassis assembly and plug-in modules. The MPS mainframe contains the following:

� A chassis with an integral backplane and front panel user interface

� A plug-in power supply module

� A system controller module

The MPS architecture supports numerous module configurations to suit your operation’s system requirements. Figure 1-1 illustrates the front panel of the MPS:

Chassis

The MPS Chassis provides the housing for up to eight functional modules, a common system controller, and a power supply. All modules, including the system controller and power supply, can easily be installed and removed through the front-panel access door.

All modules plug directly into a configurable backplane that provides high-speed transport, control and command data flow, and power distribution within the unit. The high-speed transport-multiplex (HSTM) connectivity is programmed by the system controller to correspond to the current application of the MPS unit. Interfacing with other headend equipment, Serial multi-drop and Ethernet communications with the system controller is accomplished with input/output connections at the rear of each module.

A front-panel interface is housed in the front center of the chassis. The front panel consists of a multiline LCD display with backlighting, the keypad, and status LED. The front panel interface, the JAVA™-enabled console, and headend network interface are used to configure and monitor the MPS.

The backplane enables power distribution, HSTM transmission, intermodule systems communications, and ancillary data/control connections.

The chassis also houses several fans that provide forced-air convection thermal management under supervision of the system controller.

System Control ler

The system controller is based on the Motorola 68EN360 32-bit microprocessor that provides for configuration and control of all the functional modules within the unit and network interface to all of the modules. It serves as the proxy agent for any module in network management schemes.

The system controller interfaces with each module through both serial and parallel system busses located on the common backplane. It directs code download events to its resident CPU and to the functional module CPUs as required by the headend server. The system controller directs the system and serial bus communications, and the front-panel interface and cooling functions. It controls the configuration of the functional modules and supports configuration of the MPS as the applications evolve to implement different system solutions.

The system controller also programs the backplane HSTM connections corresponding to the configuration and functionality of the MPS unit.

Power Supply

The power supply is a 200-Watt universal switched mode design. The power supply module is inserted and removed through slot 10 on the main chassis. It complies with all dc accuracy and noise requirements of the functional modules. An IEC connector on the chassis provides for multiple-country ac-mains support. The on/off switch is accessible from the front panel.

Fil ler Modules

The filler modules are simply “dummy” plastic inserts required for proper thermal management within the unit. Filler modules must be inserted into empty slots to provide for proper airflow within the chassis.

Functiona l Modules

The following list provides a sample of modules that are currently supported in the MPS system. For more information about a module, refer to the appropriate MPS module installation sheet.

DC II QAM Provides ITU/B standard 64 or 256 QAM modulation for content provided from various input channels

DHEI In Provides a DHEI interface from various headend products

DHEI Out Enables DHEI output to various headend products

DS3 Provides DS3 input/output for telecommunications interfacing, such as SONET transport of multiplexes

DVB-ASI In Converts an input ASI MPEG data stream to the MPS Infobus format

DVB-ASI Out Provides DVB ASI compatible output for an MPEG data stream in MPS Infobus format

DVB-QAM Provides DVB compatible QAM modulation for an MPEG data stream from either ASI or MPS Infobus format

DVB-SPI In Converts an input DVB SPI MPEG-II data stream to the MPS Infobus format

DVB-SPI Out Accepts MPS Infobus format MPEG-II data stream and converts it to DVB SPI format

Encrypt/Insert Performs DVB and DCII compliant scrambling, as well as insertion of local SI and PSI

L-Band Dual digital satellite receiver that receives two independent QPSK-modulated L-Band inputs and converts them to MPS Infobus format.

Remultiplexer Performs 6:2 remultiplexing and enables message insertion and extraction

Decrypt/Extract Performs DVB and DCII compliant descrambling, as well as SI and PSI extraction

JAVA-Enabled Console

Each MPS unit can be configured with a PC running an Internet browser, such as Netscape Communicator™, with a Sun™ JAVA plug-in installed. The MPS system controller contains a JAVA applet that is loaded on the host computer whenever a session is initiated and provides for an SNMP session to run between the host and the MPS. A graphical user interface (GUI) enables configuration and snapshot monitoring capabilities

For information on configuring the MPS using the JAVA-enabled console, refer to the MPS-Modular Processing System JAVA-Enabled Console Operation Manual that shipped with your MPS unit.

O v e r v i e w 2 - 5


Network Manageabil ity

The MPS supports a set of MIBs and also supports the SNMP v.1 network protocol for both configuration and status monitoring of all essential device parameters. The system controller functions as a proxy agent to the functional modules that comprise the product.

P h ys i c a l O v er v i ew The MPS chassis mounts in a standard 19-inch equipment rack in a digital headend, network hub office, or network end office. It occupies five rack units (8.75 vertical inches) and requires one rack unit (1.75 inches) of space below it for cooling airflow.

I n s t a l l a t i o n 3 - 3


2 Install rear supports to improve stability.

3 Tighten all screws.

C o n n e c t i n g t h e I n t e r f a c e C ab l e s You must first perform the following standard cabling procedures:

� Connect the Ethernet interface cable to the headend LAN for configuration/control, and status/alarm reporting using a 10Base-T connection.

� Connect the module input and output ports to other external headend equipment, such as an IRT 1000/2000, or other MPS units.

Additional cabling requirements depend on your MPS configuration. Refer to the installation sheet of each module for cabling requirements.

CAUTION !

To avoid damage to the MPS, be sure that the power supply switch is in the off (0) position, and that the power cord is disconnected before installing or removing modules.

DANGER !

Electrostatic discharge (ESD) can damage the MPS unit and circuit card assemblies. Wear an antistatic wrist strap attached to a chassis ground to prevent ESD damage.

For instructions on how to connect the module input/output cables, refer to the installation sheet that shipped with the module.

C o n n e c t i n g t h e P o w er C a b l e Connect the power cord only after you make all I/O connections. The power supply automatically senses and adapts to any input from 90 through 264 Vac and 47 through 63 Hz. The MPS is guaranteed to meet all specifications with an ac input from 100 through 240 Vac nominal and 50 through 60 Hz nominal. Motorola recommends using an uninterruptible power supply (UPS) for headend equipment.

CAUTION !

To prevent electrical shock, do not use the polarized power cord with an extension cord, receptacle, or other outlet unless all blades can be fully inserted to prevent blade exposure.

I n s t a l l a t i o n 3 - 5


C o n f i r m i n g C o r r ec t I n s t a l l a t i o n To verify correct installation:

1 Read the above caution, and then connect the power cord to apply power to the unit.

2 Verify that the power switch is on. The power switch is located on the front of the power supply module.

3 Check, after the short initialization period, that the green DC POWER indicator is on and the LCD displays the main menu.

The other LED indicators may or may not be illuminated depending on the default configuration settings and the specific signal inputs to the unit.

If the above conditions occur, the unit can be configured. Refer to Section 4, “Setup and Operation,” for information on configuring the MPS using the front panel interface. For information on configuring the MPS using the JAVA-enabled console, refer to the MPS Modular Processing System JAVA-Enabled Console Operation Manual.

Refer to the model information sheet and module installation sheets that shipped with your MPS unit for information before preparing the modules for operation.


Section 4

S e t u p a n d O p e r a t i o n

At power-up, the operating configuration of the MPS is determined either by data stored internally in Flash memory or by data that is downloaded from a Bootstrap Protocol (BOOTP) server on the headend LAN. The particular method used to set up initial operation depends on your system configuration.

After setting the initial operating configuration, modify the configuration by:

� Sending commands from the JAVA-enabled console or a SNMP network manager

� Entering new parameter settings at the MPS front panel

� Forcing a reboot to download a new configuration from the BOOTP server

This section provides information to help you operate the MPS using settings entered at the front panel operator interface. However, it is recommended that you use the MPS JAVA-enabled console to setup and operate the MPS unit. The JAVA-enabled console provides configuration and monitoring capabilities not found on the front panel operator interface. For information on setting up and configuring your MPS unit using the JAVA-enabled console, refer to the MPS Modular Processing System JAVA-Enabled Console Operation Manual and individual MPS module information sheets.

The front-panel menus and options detailed in this section reflect features available in MPS product software revision 5.1.1 and are subject to change with future software revisions.

For information on downloading data from a BOOTP server, refer to Appendix D, “Initialization Information.”

4 - 2 S e t u p a n d O p e r a t i o n


U s i n g t h e F r o n t P a n e l O p er a t o r I n t e r f a c e The front-panel interface offers an additional way to modify the configuration of the MPS. It includes an LCD and cursor-control keys through which MPS operating parameters can be set. The LCD displays a series of menus showing specific MPS parameter settings. Within a given menu, some components are:

� Display-only fields that cannot be selected or changed

� Parameter settings that can be modified — preceded by a greater than symbol (>)

� Navigational aids that branch to other menus when selected — indicated by brackets ([ ])

For example, the configuration menu shown in Figure 4-1 includes a display-only field for OAM&P in the upper-left corner identifying the menu, the SUBNET and IP options as changeable parameter settings, and the UP option as a navigation aids to branch to other menus.

Figur e 4-1 Sample MPS Conf i gur at i on menu

OAM&P IP>000.111.222.255

[UP] SUBNET>000.111.222.255

In general, changeable parameters are indicated by a greater than symbol > preceding the option, and allowable options are contained in scroll lists or in the fields that are edited directly using the up- and down-arrow keys. Navigate from option to option within a menu using the left- and right-arrow keys. Select an option using the enter key (ENT). Use the up- and down-arrow keys to scroll through the available selections and then press ENT.

R eb o o t i n g t h e M P S Use the following procedure to reboot the MPS:

1 Select ADMIN on the MPS Main menu (Figure 4-2) and then press ENT to display the Administrative menu.

2 Select REBOOT on the MPS Administrative menu (Figure 4-15) and then press ENT.

3 Press the up-arrow key. When the unit displays OK, press ENT to reboot the MPS.

The boot process has three phases:

� Power-on self-test

� BOOTP process

� Application load and execute

The power-on self-test is an internal RAM test and executes only during a power-on cold boot. The MPS will not perform this test during a reboot from the front panel.

During the BOOTP process, the MPS initializes boot file systems. The boot program performs the BOOTP process by broadcasting a BOOTP request over the Ethernet, and then waiting for a BOOTP reply. Refer to Appendix D, “Initialization Information” for more information on the MPS BOOTP process.

During the application load and execute phase, the unit operating system loads and executes, the system initializes, and the unit begins normal operation.

E r a s i n g M P S S o f t w ar e To erase the MPS System Controller application image and JAVA Console files:


2 Select ERASE_SOFTWARE on the MPS Administrative menu (Figure 4-15), and then press ENT.

3 Press the up-arrow key; when the unit displays OK, and then press ENT to execute the software erase operation of the MPS (the MPS will reboot as a result of this operation).

This command is used to ensure that all current software files are deleted before reloading the MPS with new software. The MPS software consists of multiple files; since future revisions of the MPS software may not use all current files, this command ensures there is enough space in flash memory to load a new version of the software.

This operation does not delete the configuration settings in flash memory.

CAUTION !

If the BOOTP server is NOT on the local network, the MPS will not be reloaded with software and will not be rebooted. Erasing MPS software should only be done when a new version of MPS software is to be loaded onto the MPS.



E r a s i n g M P S C o m m an d s Use the following procedure to erase all Load MPS commands from NVRAM:


2 Select ERASE_COMMANDS on the MPS Administrative menu (Figure 4-15), and then press ENT.

3 Press the up-arrow key; when the unit displays OK, press ENT execute the command erase operation (the MPS will reboot as a result of this operation).

This command is used when an MPS is experiencing problems due to invalid Load MPS commands. This may occur if the MPS was loaded with a newer version of software but contains Load MPS commands that are only applicable to an older software version.

CAUTION !

This operation deletes all Load MPS commands from NVRAM. Upon rebooting, the MPS is required to be reloaded with commands from a controller such as a DAC 6000.

Appendix D

I n i t i a l i z a t i o n I n f o r m a t i o n

When the MPS is powered-up or reset an automatic initialization process occurs, which loads the executable software and parameter settings that control MPS operations. Typically, the MPS performs initialization by self-booting from internal flash memory. However, it is possible to boot the MPS by downloading information from an external BOOTP server. This is especially helpful when you need to reload or update the MPS executable software in the field.

S e l f - B o o t O p t i o n The MPS begins initialization by broadcasting a BOOTP request over its OAM&P port. If a BOOTP server is not connected to the headend LAN to respond to the request, the MPS times out waiting for a reply and then self-boots from information stored in its flash memory.

If the flash memory is corrupted or does not contain a valid MPS executable software image, the MPS will not boot successfully. All front panel LEDs will be off except for the DC POWER LED and the front panel will display the following message:

UNABLE TO LOAD APPLICATION IMAGE! ATTEMPTING REBOOT IN XX SECONDS

Where xx is the number of seconds before the MPS reboots.

In this case, the MPS does not process any input signals and must be reinitialized using a BOOTP server. The MPS will continuously attempt to BOOTP and download a valid executable software image. Each time the MPS fails to BOOTP and load a valid image, it will reboot and attempt to BOOTP again.

BO O T P S er v e r D o w n l o ad O p t i o n To initialize the MPS by download from a BOOTP server, the following conditions must be met:

� The MPS must be connected to the headend LAN through its OAM&P port.

� A BOOTP server must be present on the LAN.

� The BOOTP server must know the MAC address of the MPS OAM&P port (MAC address of the System Controller module).

� The BOOTP server must be running a Trivial File Transfer Protocol (TFTP) server.

The MPS begins initialization by broadcasting a BOOTP request over its OAM&P port. The BOOTP server receives the MPS BOOTP request. If the BOOTP server recognizes the MPS MAC address, it provides a reply from which the MPS can initialize itself. If the BOOTP server does not respond, the MPS is booted from the information stored in flash memory.

If the MPS receives the BOOTP reply, it stores the reply and downloads the boot file specified in the BOOTP reply message. The boot file downloaded contains a list of pathnames of all MPS application files. The format of this file is defined below in the Boot File Format section. The MPS then compares the list of pathnames in the downloaded boot file to the boot file stored in flash memory.

D - 2 I n i t i a l i z a t i o n I n f o r m a t i o n


If the downloaded boot file contains pathnames that are different, or if a file pathname has a force download flag attached, or if there is no existing boot file in flash memory, then the MPS does the following:

� Downloads application files from the TFTP server specified in the BOOTP reply when any of the following conditions are met:

� A file’s pathname in the newly downloaded boot file is different than the pathname specified in the flash memory boot file

� A file’s pathname has a Force download flag attached

� There is no boot file in flash memory (all files specified in the downloaded boot file are downloaded)

� Stores the new boot file and all newly downloaded application files to flash memory

� Boots the MPS using the new application files in flash memory

If the boot file does not contain different file pathnames or there are no force download flags, then the MPS self-boots using the application files it already has in flash memory.

MPS configurations containing functional modules with on-board microprocessors, such as a Decrypt/Extract, Remultiplexer, or Encrypt/Insert module, require additional application code for each module from the BOOTP server. These files are downloaded during the system controller’s application startup process. The pathnames for these functional modules are in a secondary file that is listed in the boot file.

If any of the functional modules contain different application code, no application code, or there is a force download flag attached to a functional module file pathname, then the MPS does the following:

� Downloads the functional module application code from the TFTP server specified in the BOOTP reply.

� Stores the functional module application code to that module’s flash memory

Boots the functional module using the new functional module application code.

BOOTP Request and Reply Format

The BOOTP request and reply messages use the same packet format. The BOOTP packet format is defined in detail in the following specifications:

� RFC 1542, Clarifications and Extensions for the Bootstrap Protocol, by W. Wimer (10/27/93).

� RFC 1533, DHCP Options and BOOTP Vendor Extensions, by S. Alexander and R. Droms (10/08/93).

Refer to these specifications for complete information on the BOOTP packet format and field descriptions.

I n i t i a l i z a t i o n I n f o r m a t i o n D - 3


Boot Fi le Format

The boot file specified in the BOOTP reply is a “file of files,” that is, it serves as a pointer to several other files containing configuration information for the MPS. The MPS uses the filenames in the boot file to determine whether the boot information in the BOOTP reply is different than the boot information it has stored in memory. If a filename in the boot file is different, the MPS downloads the boot file and reads it to obtain the names of the following other files it requires for initialization:

Executable code file Contains MPS operating system executable and application software

Dynamic configuration file

ASCII file containing MPS operating parameter settings

Static configuration files

Multiple files to configure MPS processing tasks and messaging queues, TCP/UDP port names and numbers, as well as other LAN elements names and IP address assignments

After downloading and reading the boot file, the MPS downloads each file referenced in it.

Like the BOOTP request and reply message, the boot file and all downloaded files are transferred using UDP, which does not include error checking. Because undetected transmission errors during download process can cause initialization failure, always retry the initialization at least once before searching for a specific fault.

The boot file name must have an eight-character base and a three-character file extension, and all characters must be lower case.

Within the boot file, all lines must be either comment lines or data lines, and each line must be terminated with a carriage return or a carriage return+line feed. Comment lines begin with a # character in the first position. Data lines define the names of referenced files using two fields separated by any number of spaces or tabs:

� The first field identifies the file by its absolute file name as stored on the BOOTP server

� The second field identifies the file by its symbolic name as used by the MPS

� A third optional field can be used to force a file to be downloaded. This field is added to the end of a data line, separated by a space or tab. This field by default is not specified and should only be used by advanced users. To force a file to be downloaded, add an “F” to the end of a data line referencing a file. Note that flagged files will only be force downloaded when the MPS receives a BOOTP reply during the boot phase of the MPS.

MPEG-2 is typically compressed at higher than 5Mbs and intended for higher quality broadcast uses.

OAM & P

A telephone industry acronym referring to operations, administration, maintenance, and provisioning. The term refers to software required to generate the reports and commands needed to control all network equipment. The OAM&P port is a network (Ethernet) port through which a device communicates with the headend network. The OAM&P port is assigned a hardware (MAC) address at the factory; this MAC address is used for communication with the bootp server before the network (IP) address is assigned to the port.

Packet Ident i f ier (PID)

A number assigned to MPEG transport packets to identify the information stream to which they belong. The PID number is assigned in the packet header, and all packets from the same stream have the same PID number. A 13-bit number included in MPEG-2 transport packet headers.

Quadrature Ampl i tude M odulat ion (QAM )

A data modulation technique used to convert digital program information for delivery in cable TV systems over in-band frequencies. A form of double sideband modulation. The data stream is split into two half-rate streams. One of the data streams modulates a sine wave carrier, the other a cosine carrier at the same frequency. The resultant signal resembles a vestigial sideband signal with no pilot carrier present.

Quadrature Phase Shi f t Keying (QPSK)

A digital modulation method that combines two carriers that are 90 degrees out of phase (in quadrature), resulting in four possible phase states.
