Addendum

3.4.1 Description

(Paragraph 3) Delete the following sentence: Modems not part of a backup pool will not be learned.

3.4.6 Configuration Copy

The Configuration Copy is a feature that enables a user to store/retrieve up to five modem and interface card configurations in non-volatile memory. These are in addition to the current running configuration.

The interface card configurations are tagged to the slot, and are stored in the switch. The modems, on the other hand hold their own settings. The user can copy from and copy to any configuration in memory including the current running configuration. Source and destination configurations must be different.

When instructed to copy a configuration, the switch sends a command to the modem to copy the configuration, and if successful, the switch updates the slot configurations as well. If the destination configuration is the current configuration, the modem re-initializes itself and uses the new settings. The switch interface card is only updated when the destination configuration is the current configuration.

A user must be careful not to copy onto the current configuration unless that is desired, interruptions in traffic will occur.

Section 1 - RCS10 Redundant Communication System Description

1.1 Introduction

As shown in Figure 1-1, Radyne ComStream's RCS10 is a complete, self-contained modem system with all modems, terrestrial interfaces and redundancy switch functions included in a single equipment cabinet that is 10 rack units high (17.5 inches). This compact and versatile common equipment package is unique and offers unsurpassed performance, reliability and flexibility. In addition to full support for Intelsat's IDR/IBS services, the system may be operated in closed networks.

The built-in M:N Redundancy Switch is an intelligent microcomputer controlled system, capable of controlling up to ten DMD10 modems in a variety of configurations.

The switch can be operated automatically, in which case an automatic back-up of a failed on-line modem occurs after a preprogrammed delay. The switch may also be operated manually, allowing the operator to manually switch in the backup unit. Front panel controls and indicators provide for auto/manual configuration, as well as display of online/off-line status information for all modems in the redundancy configuration.

All switch and modem operating parameters, such as variable data rates and selectable IBS/IDR framing, are easily set and changed by the operator. The modem and redundancy switch monitor and control functions are available at the front panel of the system (Refer to Section 3). All functions may also be accessed through a terminal or a personal computer via a serial link (RS485 or Ethernet) for complete remote monitoring and control capability.

Section 2 - Installation

2.0 Installation Requirements

This chapter instructs the user in the methods for setting up and installing an RCS10 Redundant Communication System into a Satellite Modem system.

2.1 Unpacking the System Unseal the shipping cartons taking care not to damage the cartons, the packing material or the

equipment inside. The cartons and the packing material should be saved in the event that an RCS10 will need to be reshipped. Examine the exterior of the units for any possible shipping damage.

2.1.1 List of Items Carefully remove the units from the cart ons. In addition to this manual, be sure that the following

items are present:

• RCS10 Redundant Communication System

• 2 AC Power Cords

• RCS10 System Test Data Sheet

2.1.2 In Case of Shipping Damage If any shipping damage is discovered on any of the above listed equipment, promptly contact the

transporter and file a damage claim. The shipping company is responsible for any damage caused during shipping. Radyne ComStream Corporation should also be contacted.

Damage as a result of transportation is not covered under the Radyne ComStream Corporation Warranty. Refer to the Warranty section in the front of this manual for further information.

The procedure for returning faulty or damaged equipment is contained in the warranty section in the front of this manual.

2.1.3 Test Data Sheet Each RCS10 Redundant Communication System is shipped with a Test Data Sheet. This report

contains information on the results of the Switch quality control testing. The report also includes information pertaining to the system settings that were made at the factory. Radyne ComStream Corporation recommends that the user save this report for future reference.

2.2 Site Considerations Adequate site planning and preparation simplifies the installation process and results in a more

reliable system. The user should ensure that the site has adequate electrical power, environmental controls and

protection against sources of electrical radiation and interference.

2.2.1 Power Sources The power sources should be properly grounded and as free as possible from electrical interference.

If a redundant configuration is to be used, then each power cord on the RCS10 must be plugged into its own separate power circuit. Each circuit must have its own independent circuit breaker.

Grounding is ac hieved automatically when the three-prong power plug is inserted into a power receptacle. This should be checked by testing that there is no voltage present between the chassis of the Switch and the power line ground.

Page A -1

RCS10 Technical Specifications Appendix A

The protective ground must not be bypassed with a three-prong to two-prong adapter or defeated in any way. Defeating the ground may result in operator Injury or damage to the system.

2.3 Rack Mounting To allow for the easy installation of cables and adequate air circulation through the units, a

minimum of six inches of clearance must be provided at the sides and rear of the units. In addition, the RCS10 requires a minimum of 1-3/4 inches (1U) of clearance at the top of the unit.

The RCS10, when fully populated, weighs approximately 100 lbs. When installing into a rack enclosure, a minimum of two technicians are required to minimize personal hazard.

2.3.1 DMD10 (Modem) Installation into the RCS10 Chassis The RCS10 is shipped with the Modems (DMD10s) and External Reference Card packaged

separately for shipping purposes. All modems are universal and may be installed into any slot (1-9). The External Reference Card is installed in slot 10.

2.4 Configuring the system

If either AC line cord remains connected to the RCS10, dangerous AC voltages will be present within the unit and the cooling fans will also be operational. Although AC power is not present on the backplane, care must be taken when installing or removing a plug-in module since DC voltages will be present.

Before powering up the RCS10 or attaching cables to J12 (Sync Data RS422/RS485/V.35), the following steps MUST be verified in order to avoid damage to the equipment. Ensure the following:

1. The cables must be wired correctly. Refer to Table 2-1, J12 Sync Data,

RS422/RS485/V.35;

2. The External Interface is programmed or supports the appropriate Interface type: RS232,

RS422, or V.35;

3. The Universal Interface Module (UIM) is configured for the appropriate Interface type:

RS232, RS422 or V.35.

Page 1-2

This is EXTREMELY IMPORTANT as the Interface pins operate at different voltage levels

depending upon the Interface type selected. SERIOUS DAMAGE may occur, for example, if

the External Interface is operating at V.35 voltage levels and the Universal Interface is

configured for RS422 voltage leve ls.

2.4.1 Modem Connections

All modem connections are made to labeled connectors located on the rear of the unit: The connector definitions and pinout tables are shown below, and are those on the RCS10 unit and Universal Interface Modules. Any connec tion interfacing to the modem must be the appropriate mating connector. Refer to Figures 2-2 and 2-3 to locate the rear panel connectors.

2.4.2 Connector Pinout Tables

The following paragraphs and tables contain the pinout information for the various data/IF connectors located on the rear panel of the RCS10.

2.5 External Reference Card Section The External Reference Card plugs into slot 10 on the rear of the RCS10 (refer to Figure 2-3). The

External Reference module has one external IF reference input which is distributed to all ten DMD10 modems. Each modem’s on-board system oscillator can be individually locked to the external reference.

Additionally, the external reference module can be equipped with a 10-7 high stability reference oscillator that is distributed to all ten DMD10 modems providing a low-cost high-stability option. An External IF Reference Output (J2) is also provided for distribution to other equipment.

Also, the external reference has one BNC clock input (J3) that is distributed to all ten modems. Each modem control can independently select this external clock as its TX clock and/or RX buffered clock source. The connections and descriptions are as follows:

J1 - EXT IF REF IN (BNC) J1 provides an input for external clocking that can be selected by a particular modem (1-9). A

modem selecting this external clock will then lock its IF circuitry to this signal.

J2 - EXT IF REF OUT (BNC)

J2 provides a clock reference output that may either be the same as the input to J1 discussed above or the onboard RCS10 high-stability reference.

J3 - EXT BNC CLK IN (BNC)

J3 is the External BNC Clock Input that can be selected by a particular modem (1-9) for data clocking.

J4 - Remote RS485 I/O (9-Pin Female ‘D’)

J4 is the Remote RS485 I/O port. See Table 2-8 for the connector pinouts.

J5 - Remote Terminal Port (9-Pin Female ‘D’)

J5 is the RS C10 Remote Terminal Port. See Table 2-9 for the connector pinouts. J6 - System Fault Summary Relays (15-pin Female ‘D’) J6 is the System Fault Summary Relays connector. See Table 2-10 for J6 connector pinouts. J7/J8 - Optional Remote Ethernet Connections - J8/10BASE-T (Twisted pair), J7/10BASE-2

RCS10 Redundant Communication System Operation

Section 3 - Operation

3.1 Operating Procedures

Operation of the RCS10 consists of controlling the unit operating parameters and monitoring status and responses via one of the control interfaces. Control options for the RCS10 are as follows:

1. Front Panel Control

2. Terminal Mode Control

3. Remote Computer Mode Control

4. Remote SNMP Control

Any of the above methods may be used separately or together to monitor and control the RCS10.

3.1.1 Front Panel Control

The front panel of the RCS10 allows complete control and monitoring of all Modem and Switch parameters and functions via a keypad, LCD display, Modem and Switch status LEDs and LED indicators on the DMD10 modems.

3.1.2 Front Panel Layout and Features

The RCS10 Front Panel layout is shown in Figure 3–1. The front panel is divided into the following functional areas: the LCD front panel display, the Modem and Switch, the Keypad and the LED Indicators, each described below. Refer to Table 3-1 for a brief description of the RCS10 front panel controls and indicators.

3.1.3 Front Panel LCD Display

The front panel display is an 8 line by 40 character LCD display. The display is lighted and the brightness can be set to increase when the front panel is currently in use. The LCD display automatically dims after a period of inactivity that is programmable from the front panel.

The display has two distinct areas showing current information. The bottom row of the display shows the functions of each of the four softkeys (labeled ‘S1’, ‘S2’, ‘S3’, and ‘S4’ in Figure 3-1). If a softkey provides a function, then that function will be displayed just above the corresponding key. If no function is displayed above a softkey, then there is no function associated with that key, and pressing it will have no effect. The rest of the display shows current parameter and status information. The LCD display is a window into a large matrix of switch and modem parameters that can monitored and changed from the front panel.

The ten keys contained in the MODEM and SWITCH are used to view and change a particular set of control parameters as described by the label next to the key. Each of these keys are used to display a series of menu trees that are displayed on the LCD and used to view and enter control parameters. These keys and their corresponding menus are described separately below:

3.1.4 Front Panel LCD Indicators

There are sixteen (16) LEDs on the RCS10 front panel to indicate the selected LCD menu tree and current switch status. The color of the illuminated LEDs on the front panel indicate overall switch status according to the following key: An illuminated green LED indicates normal operation. An illuminated yellow LED indicates a condition that is not proper for normal operation, however, all satellite channels are currently on-line. An illuminated red LED indicates that the RCS10 was unable to provide redundancy protection for a satellite channel, and at least one channel is off-line. For the purposes of this discussion, the LEDs are separated into two major groups, MENU LEDs and SWITCH STATUS LEDs. The Menu LEDs are those LEDs immediately next to the front panel

Page 3-4 TM058 - Rev. 2.3

RCS10 Redundant Communication System Operation

3.1.7 Menu LED Indicators Each Menu LED corresponds to the MODEM group or SWITCH group key located to the right of the

LED. When lit, these LEDs indicate which menu tree is currently active on the LCD. For example, if the SWITCH-TEST LED is illuminated, then the LCD is displaying one of the menus that allow control of RCS10 test modes.

3.1.7.1 SWITCH STATUS LED Indicators (Color as indicated below) Normal: Green - indicates that the unit is currently under power Major Alarm: Red - indicates that at least one satellite channel did not receive redundancy

protection and is off-line. Minor Alarm: Yellow - indicates that a redundancy warning exists and the RCS10 may not be

providing redundancy protection.

Test Mode: Yellow - indicates that the switch is performing one of the system tests. Event: Yellow - indicates that a condition or system event has occurred that the RCS10

has stored in memory. The events may be viewed from the Front Panel or from the Terminal port.

Remote: Green - indicates that the unit is set to respond from either the Terminal port or the Remote M&C port

3.1.8 Local/Remote Control The switch operates in both Local and Remote modes. In Local mode, changes to the system’s

configuration can be implemented only from the RCS10 front panel. Remote access to the system is limited to a query of status information only. While in the local mode, the switch responds to remote commands with the Error Message ‘Not Allowed in Local Mode.”

In Remote Mode, configuration commands can be issued from a ‘Dumb’ terminal, a computer, or a network through the system’s built-in Ethernet channel. The terminal and computer interfaces to the switch are mutually exclusive. In Remote mode, all front panel switches used to change operating parameters are locked out and changes can only be made remotely. LEDs and displays remain operational, however.

The only configuration command allowed into the system, whether it is in Local or Remote mode, is a change in Control mode. The user can command the system to go into local or remote modes from the front panel, dumb terminal, computer M&C or a network.

3.1.9 Terminal Control The switch will emulate a WYSE-50, ADDS -VP or VT-100 dumb terminal. It will display a Main

Menu and prompt the user to select the equipment to monitor and control. If the system is in Remote mode, configuration paramet ers can be altered. If the system is in Local mode, however, no commands are allowed except for a control mode change.

Terminal mode has several basic display screens that show the current status of the RCS10’s modes and variables. The screens will show both status and control variables. Only the Control variables can be modified. To modify a variable, the user will enter the variable number at the prompt followed by a carriage return. The cursor then will move to the variable area and the user will either type in a new value or press the space bar to scroll through the available selections.

3.1.10 Remote M&C Interface The interface to a remote computer and monitor system is done through the Radyne ComStream

RLLP protocol. There are two types of packets the switch can receive; Direct and Encapsulated. Direct packets are those intended for the switch, and Encapsulated packets are those intended for the modem or the UIMs. The Encapsulated packets are embedded in the switch’s relay command.

TM058 - Rev. 2.3

Page 3-5

Operation RCS10 Redundant Communication System

3.1.11 SNMP Control

The Simple Network Management Protocol (SNMP) is used to monitor and control the RCS10 Switch parameters when the Switch is connected to a network. On a network, a client is one host, an SNMP Manager communicates with a server in another host, an SNMP Agent. The Manager, a remote M&C, requests the agent (RCS10 Switch) to read or write information (objects) in a Management Information Base (MIB) resident in the Agent. Refer to Addendum A in the back of the manual for additional information and a complete compilation of the RCS10 MIB.

3.1.12 Manual/Automatic Backup Modes The switch operates in both Manual and Automatic backup modes. In Automatic Mode, a failed

unit will be automatically replaced with a Backup unit if a Backup unit is available. However, if an online Modulator or Demodulator fails while it is set to Manual mode, it will not be automatically backed up.

There are two types of Automatic backup modes; Revertive and Non-revertive. In Automatic Revertive mode, a failed unit is replaced with the backup unit after the fault delay time has passed. The failed unit continues to be monitored and if the failure condition clears itself, and another failure occurs with no available backup units, then the Switch will automatically ‘Unback’ the passing unit and then backup the newly failed unit. In Automatic Non-Revertive mode, a failed unit is replaced by the Backup unit after the Fault Delay time has elapsed. However, if the failure condition clears itself, the Switch does not return the failed unit bac k online if another monitored unit fails and no backup units are available. The failed channel can be unbacked manually using the <BACKUP> front panel selection.

3.1.13 Standby Modes A backup unit can be set to three standby modes; self-test, hot standby and preemptable. In self-

test mode, the backup Modulator’s IF output is looped into the IF input of the backup demodulator and performance is continually checked.

In hot standby mode, the backup modulator and/or demodulator settings are matched to that of a priority online modulator and/or demodulator so that if a modulator and/or demodulator fails, it will immediately be replaced by a backup. The other modems are still monitored and will be backed up, but the switchover will be longer.

In preemptable mode, the backup modulator or demodulator is used online. However, if another modem, covered by the backup fails, the backup will be preempted and will backup the failed modem.

3.1.14 Test Port Operation (Operational on Backup Modem 2 Only) The backup channel’s terrestrial interfaces can be used to test the operation of the channels that

they cover. On the modulator side, the test port can be tied to any modulator that the backup is monitoring and used to inject baseband test signals into the online modem. On the demodulator side, the test port is used to monitor the demodulator output of the online modem. The user can set the test port selections by specifying the modulator and/or demodulator that is connected to a backup’s Mod and Demod test ports from any of the available user interfaces.

3.1.15 Backup/Online When a modem is first installed into the RCS10, it is set up as an online unit by default. It is up to

the user to change its configuration from ‘online’ to ‘backup,’ and to set up a backup pool for it if configured as a backup, or add it or remove it from a backup pool if set up as online. These configuration settings are performed on the front panel through the <SWITCH CONFIG> key.

Page 3-6 TM058 - Rev. 2.3

RCS10 Redundant Communication System Operation

The backup algorithm operates in both manual and automatic reve rtive and non-revertive modes with automatic backup assignments and priority levels. There is a limit on the total number of backup attempts for any prime. Once a failed prime is flagged for backup, a ‘ * ‘ is displayed on the prime backup assignment front panel screen to indicate a backup is in progress. A ‘ B ‘ or a ‘ BB ‘ will replace the ‘ * ‘ if the backup is successful, otherwise another backup attempt is made. After three failed backup attempts, an ‘ F ‘ or ‘ FF ‘ is displayed and the prime is remove d from the ‘backup modem’ backup pool. No further backup attempts are made. The backup modem is now available to backup any other failed prime in its pool.

There are two ways a failed prime can be placed back in the backup pool. The first is when the summary fault status changes, the other is through user intervention. Setting of the backup assignment, priority, and backup modes clears the total number of backup attempts.

3.2 Guide to Front Panel Monitor and Control

The front panel can be used to perform complete monitor and configuration of the RCS10. The operation of the front panel becomes easy after a short period of use in which the user becomes familiar with the basic concepts and operations. Front panel control is implemented as a series of data entry ‘screens.’ The screens are organized into several groups that contain related parameters and status values. Screens allow the modification of control parameters, display of status parameters, or both. Different screens will be displayed on the front panel based on keypresses from the front panel. The screens will be displayed in order; this order defines the ‘menu tree’ for a particular group of related screens.

3.2.1 Remote Port Control

When in Computer Mode, the RCS10 uses an RS485 Serial Control Port (Remote Port) for use with computer-controlled remote monitor and control systems. The Remote Port is a 9-pin female ‘D’ sub connector (J3) located at the rear of the unit on the External Reference Card. The pinouts for the remote port are listed in Section 2. The remote port supports standard UART asynchronous protocol with 8 data bits, no parity, and 1 stop bit (8N1) at 4 baud rates: 9600, 4800, 2400, and

1200. The Remote Port utilizes a binary protocol called Radyne Link Level Protocol (RLLP). The RLLP is a multi-drop, packet -oriented protocol with handshaking, and is described in Appendix B at the end of this manual.

3.2.2 Terminal Port Control

When in Terminal Mode, the RCS10 uses an RS232 serial port (Terminal Port) for use with a separate terminal or computer running a terminal emulation program. The Terminal Port is a 9-pin female ‘D’ sub- connector (J2) located at the rear of the unit on the External Reference Card. The pinouts for the RS232 port are listed in Section 2, “Installation.” The terminal port supports standard UART asynchronous protocol with 8 data bits, no parity, and 1 stop bit (8N1) at 3 baud rates; 19200, 9600, and 2400.

The Terminal Interface is menu-driven and allows complete monitoring and control of all RCS10 parameters. Three terminal emulation protocols are supported: DEC VT-100, Wyse-50, and ADDS Viewpoint. The terminal display is a full-screen presentation of the current status of the RCS10 modes and variables. The screens will display both status and control variables. The status variables cannot be modified, but the control variables can be. Each variable that can be modified will have a display number next to the value. Changing the value is accomplished by typing the number of the variable to be changed. Two types of input may then be requested from the user. If the input is multiple choice, the space key must be pressed to cycle the available choices until the desired value is displayed. The ‘Enter’ or carriage return key must then be pressed for the new value to take effect. If the input is numerical, the desired value should be typed using number keys

TM058 - Rev. 2.3

Page 3-7

Operation RCS10 Redundant Communication System

(‘0’ to ‘9’), then pressing the ‘Enter’ key. An input can be aborted at any time by pressing the ‘ESC’ key. If an invalid value is entered, an error message will be displayed on the terminal.

Following a valid input, the RCS10 places the new settings into nonvolatile RAM, changing the switch configuration immediately and storing the configuration for the next time the unit is powered up.

3.3 Backup Ha ndler

The switch operates both in manual and automatic backup modes. In automatic mode, a failed unit will be automatically replaced with a backup unit if a backup is available. However, if an online Modulator or Demodulator fails while it is set to manual mode, it will not be automatically backedup. Backup mode is accessed in the <CONFIG SWITCH> menu.

To manually back up a modem, set the desired backup (1 or 2) to ‘Manual’ in the <CONFIG SWITCH> menu and then in <FORCE MANUAL BACKUP>. Also, in the <CONFIG SWITCH> menu, select the backup that is in ‘Manual’ mode and enter the number of the prime modem to be backed up. Backup 2 can select available modems between 1-8. Backup 1 can select available modems between 1-8 or 1-9 if backup 2 is set for traffic.

There are two types of Automatic Backup Modes: Revertive and Non-revertive. In Revertive mode, a failed unit is replaced by the Backup unit after the fault delay time passes. The failed unit continues to be monitored, and if the failure condition clears itself and another failure occurs with no available Backup units, then the SWITCH will automatically unback the passing unit and then back up the newly failed unit.

In Non-revertive mode, a failed unit is replaced by the Backup unit after the fault delay time passes. However, if the failure condition clears itself, the SWITCH does not return the failed unit back online if another monitored unit fails and no Backup units are available. The failed channel can be unbacked manually by setting the BACKUP unit to manual using the front panel <BACKUP> selection located in <CONFIG SWITCH> and instructing it to manually back modem #0.

There are two types of delays available to the user in the RCS10 Switch. The Fault Delay time for each Modulator and Demodulator is preprogrammed by the operator to be between 0 and 299.9 seconds through the <CONFIG SWITCH> Menu. The SWITCH continually checks for the return of a good signal during the delay time. If the signal returns, no switchover takes place and the timer is reset. If more than one unit fails, the first one to timeout will be the first one that is replaced until no Backup units are available.

If the unit is still inoperative at the end of the delay time, and the backup unit is available, then the backup tak es place. If the backup unit is in both automatic and hot standby modes, then if the online unit (the one the backup is standing by for) fails, it will automatically be backed-up regardless of fault delay.

The other type of delay available to the user is the Acquisition Delay. This is the amount of time it takes the Demodulator to acquire lock. When a Prime fails, the backup unit has up to the programmed Acquisition Delay to lock. If it fails to lock, a Major Alarm is asserted along with a descriptive event logged in the Event Buffer. Backup status faults will also be generated to ‘Flag’ the unsuccessful backup.

The Backup Modem has up to three attempts to successfully backup a prime. If it fails, an ‘F’ or ‘FF’ is displayed on the Backup Summary front panel screens and the Prime is removed from the ‘Backup Modem’ backup pool. No further backup attempts are made.

Nine different priority levels may also be set and are used by Revertive switching to make a decision to drop a link that is already being backed up in favor of another link of higher importance. As long as a free backup modem remains, that backup will handle the outage. Should no free backups exist, then any outage is considered for backup on a priority basis. Priority is set with 1 being

Page 3-8 TM058 - Rev. 2.3

RCS10 Redundant Communication System Operation

highest and 9 being lowest priority. Priority setting may be accessed in the <CONFIG SWITCH> menu.

3.3.1 1:N or 2:N Switching

The SWITCH is very flexible in set -up options. It may be set up as M:N or 2 1:Ns simply by instructing the switch as to which backup is assigned which primes for auto-mode backup. This is located in the <CONFIG SWITCH> menu. Setting Backup 1 and Backup 2 for M/D or MD backup (Mod/Demod or Modem switching respectively) of all 8 primes would give a 2:8 switch setup. If backup 1 were set for M/D or MD backup of prime 1, 2, 3 and backup 2 were set for M/D or MD backup of primes 4, 5, 6, 7, 8, then this would net two 1:N setups with the first being a 1:3 and the second being a 1:5. Any combination using the available backups and primes can be achieved.

Additionally, if backup 2 were set for traffic (again in the <CONFIG SWITCH> menu) instead of backup operation, you could then achieve a switching of 1:9.

3.4 RCS10 ‘Learn’ Feature This section describes the Learn and the Backup Test feat ures

3.4.1 Description

During backups, when primes modems are failing, it is essential that a good known system configuration be used. In order to ensure that the backup process is successful, the Learn and Backup Test features are used to complement the backup algorithm by providing a snapshot of a known good state of the system.

The switch holds images of all modems current status and control parameters. These can be viewed and/or modified through the front panel, computer, and Ethernet interfaces. Once satisfied with the system’s operation, the user can, at any time, initiate a Learn of one or all the modem parameters. The latter are to be used during backups (learned modem configuration) and are stored in nonvolatile memory.

The Backup Test Feature can be used in conjunction with the Learn Feature to ensure that the backup is capable of backing up primes that are part of its pool.

Here is the three-step process:

- Assign a backup(s) to the prime modem(s) to be learned;

- Learn the prime modem(s);

- Ens ure that the assigned backup(s) is capable of backing up the prime modem(s).

It is essential that the user learn the configuration of the prime modems in the system. During backups, if the prime modem configuration has previously changed, the backup modem(s) will be configured with the older parameters.

Learned and current modem configuration images are periodically monitored for any discrepancies. A switch minor alarm as well as module alarm status bit(s) are asserted if there are differences between the two. To draw the user attention to the prime modem configuration change, the switch minor alarm LED flashes if the configuration change alarm status is not masked. Once a modem is part of an auto backup pool, the user shall be notified of any changes to the modem configuration. User intervention will be required to acquire a new modem’s configuration.

3.4.2 Alarms & Reports Every time a modem is queried, its learned and current configurations are compared. Any

differences are time/date stamped and logged as a warning event. A switch minor alarm and a bit(s) in the switch module status alarms are asserted as well. If the prime modem configuration change alarm status is not masked, the switch minor alarm LED also flashes.

Backup modem is unable to backup prime. The return error,

Every time a backup test fails, an event is time/date stamped and logged as an alarm event. A switch minor alarm and bits in the switch module status alarms indicate the backup test status of the particular prime. These bits reflect the status of both backup 1 and 2.

Popup error messages or error returns are also generated whenever commands to learn a modem or modems are unsuccessful. Possible errors are as follows:

MODEM_NOTPRESENT = Modem not present MODEM_NOBACKUP = Modem not part of a backup pool MODEM_COMMERROR = Modem communication error Popup error messages or error returns are also generated whenever commands to test a backup’s

capability to backup primes that are part of its backup pool. Possible errors are as follows: MODEM_NOTPRESENT = Modem not present BACKUP_NOTPRESENT = Backup modem not present IOCARD_NOTPRESENT = I/O card not present MODEM_NOBACKUP = Modem not part of a backup pool MODEM_COMMERROR = Backup modem communication error MODEM_PARAMETER = Backup modem is unable to backup prime. The return error in this case might be specific to the parameter in question MODEM_CONFIGCHANGED = Modem’s configuration has changed Popup error messages or error returns are also generated for the copy modem configuration

command. Possible errors are as follows:

MODEM_NOTPRESENT = Modem not present IOCARD_NOTPRESENT = I/O card not present MODEM_COMMERROR = Backup modem communication error MODEM_PARAMETER = in this case, might be specific to the parameter in question NOTE: During backups, the switch uses the learned parameters of the primes it’s attempting to

backup. It is essential that the user learns the current configuration of the primes to guarantee user desired operation. The learned parameters are also used in the Backup Test and Copy features.

3.4.3 Service Mode

On occasion, it is necessary to remove a modem from the RCS10 chassis for service (hardware changes, firmware updates etc.) If the Switch is in Automatic Backup Mode, the modems must be placed in ‘Service Mode’ to remove it from the Backup Pool and stop a backup from taking place. To place a modem in Service Mode, press the front panel ‘Config System’ key and then press softkey ‘S4’ (Next) until the ‘Modem Service Mode’ screen is displayed. To modify a Modem Service selection, press softkey ‘S1’ (Service), and use the right and left arrows to highlight the modem to change and then press softkeu ‘S3’ (TOG MODE) to toggle the Modem Service selection. Finally, press the Enter key ‘ENT’ for the selection to take effect.

3.4.3 Interface Card (I/O) Configuration

Page 3-16 TM058 - Rev. 2.3

RCS10 Redundant Communication System Operation

Each Modem and I/O card in an RCS10 slot operates in sync. Each slot in the RCS -10 system consists of a DMD-10 modem and an IO card. The modem parameters are stored in non-volatile memory allowing the modem to return to its previous settings and configuration upon reset, power up, or hot insert. The I/O card parameters, on the other hand, are stored in the switch CPU card and are associated with the particular slot the I/O card is plugged into. This allows the newly inserted I/O card to match the operation of the modem already present in that particular slot. For instance, if an I/O card is moved from slot 2 to slot 4, it will get re-programmed with the saved parameters of slot 4. It is necessary for the us er to make sure that the I/O card is programmed with the desired parameters. Reprogramming the overhead and the interface types is recommended and might be necessary.

Due to the nature of the RCS10 system whereas the DMD10 modems are completely independent of the interface cards, the channel’s overhead parameters, both Mod and Demod, must be entered or reentered on initial setup of a channel. This is also true if a DMD10 modem is moved from one channel to another or if an interface card is moved from one channel to another. This can be done by either reentering the framing (96 Kb for IDR, 16/15 for IBS) or by reentering the mode setting (IDR or IBS) under both the Mod config. and Demod config.

When a prime is backed up, the backup modem uses the prime’s I/O card to carry traffic. At times, the prime is placed in Service Mode, modified and reinserted into the RCS10 chassis. The user must not make any modifications to the interface card as it may cause interruptions in traffic. Some modem parameters such as Ove rhead, ESC Source and External EXC Source are relayed to the I/O card as well.

3.4.4 Modem/I/O/Switch Communications

The RCS10 Switch M&C periodically queries the Modems and I/O card for current configuration and status. upon power-up or hot insert, the I/O cards are initialized according to the parameters associated with the slot. In case of failure, the Switch M&C logs a descriptive event in the event log, sets a Minor Alarm, and asserts the appropriate faults. It will then periodically attempt to initialize the failed I/O card.

The Modem parameters on the other hand are saved in the Modem’s non-volatile memory allowing the modem to return to its previous settings. The Switch periodically queries the modem for updates to its configuration. When a communication failure occurs, the Switch M&C takes the appropriate actions, but there are side-effects; the front panel updates seem sluggish and commands to the other Modems and I/O cards take longer to execute. The communication problems should be resolved for proper operation to resume. The ‘MODEM CHANNEL CONNECTION TEST,’ Alarm Status and Event Log should be used to help determine where the communication failure is occurring.

3.4.5 Configuration Copy

A user must be careful not to copy onto the current configuration unless that is desired, or

TM058 - Rev. 2.3

Page 3-17

Operation RCS10 Redundant Communication System

disruptions in traffic will occur.

3.5 Modem Checkout and Initial Power-up

The following descriptions assume that the RCS10 is installed in a suitable location with AC power applied to both slide out power supplies.

NEVER apply power to the slide-out power supply modules unless they are firmly seated in the RCS10, as there is a potential shock hazard at the AC/DC converter within the module.

Turn the unit on by switching both AC power switches (located above the power entry connectors at the rear of the RCU10) to the ‘ON’ position. At power-up, the switch processor performs a selfdiagnostic before beginning the primary monitor/control program. If a failure is detected during the power-up tests, the Major Alarm LED will illuminate. If there is no failure, there will be no indication on the front panel.

The initial field checkout of the switch can either be accomplished from the front panel or from a terminal connected to the Terminal Port. Using a terminal has the advantage of providing full screen access to all of the switch parameters, but requires a separate terminal or computer with terminal emulation software. If a terminal is used, the Terminal Port baud rate must first be set from the front panel.

NOTE: Upon power-up or ‘Hot Insert’ of the Universal Interface Modules (UIMs), the operator must set up the UIMs to the desired Interface Type. This can be accomplished by depressing the front panel ‘INTFC CONFIG’ key, selecting soft key ‘1’ or ‘2’ and then programming the applicable UIM interface type.

3.5.1 RCS10 Front Panel Data Entry Screens Control from the front panel of the RCS10 is implemented through a series of data entry screens

that are displayed on the front panel LCD. The screens are organized into groups of related parameters and status values. Within a single group, the screens are displayed on the LCD in a particular order; this order defines the ‘menu tree’ for that particular group of screens. Each menu tree is accessed by depressing one of the following keys on the RCS10 front panel:

MOD CONFIG, DEMOD CONFIG, INTFC CONFIG, MONITOR, TEST and ALARMS in the MODEM group, or CONFIG SWITCH, CONFIG SYSTEM, MONITOR/ALARMS , and TEST in the SWITCH group. For example, pressing the CONFIG SWITCH key causes CONFIG SWITCH SCREEN 0 – BACKUP MODE CONFIGURATION to be displayed on the LCD. The first screen of each menu tree is called the top level screen for that particular menu tree.

3.5.2 Basic Front Panel Controls

Once the top level screen for a particular menu tree is displayed, either the parameters on the screen can be edited, the next screen in the menu tree can be displayed, or the previous screen in the menu tree can be displayed. Each of these actions is discussed in detail below.

3.5.2.1 Changing Parameters from the Front Panel

Whenever there is a parameter that can be changed or edited from the front panel, the first character of the parameter value will highlight with a blinking box. This box is called the cursor, and the cursor defines what parameter is currently being edited. If there are several parameters on one screen, two of the softkeys will be labeled ‘<---’ and ‘--->‘. These keys are used to move the cursor from one parameter to the next, and therefore any of the configuration parameters displayed on the screen can be edited. The left arrow (‘<---’) moves the cursor to the left, and the right arrow

Page 3-18 TM058 - Rev. 2.3

RCS10 Redundant Communication System Operation

(‘--->‘) moves the cursor to the right. If the cursor is at the beginning or end of a row containing several parameters, the cursor will wrap to the opposite side of the display.

Editing a configuration parameter value is accomplished in one of several ways. If the parameter is numerical, the desired value should be entered from the numeric keys. Occasionally, the numeric values can be incremented and decremented by pressing softkeys labeled ‘UP’ and ‘DOWN’ respectively. In either case, when all of the numerical parameters have been edited to the desired values, pressing the ENTER key will execute a load of the parameters into memory, and then advance to the next screen in the menu tree. Pressing the CLEAR key will not execute a load of parameters into memory (the original parameter values before editing will be retained), and then move to the previous screen in the menu tree.

If a parameter has a non-numeric value, the allowed values for that parameter can be edited by pressing softkeys with the desired values. In cases where there are multiple parameters shown on a screen, the values are edited with the softkeys and loaded by pressing the ENTER key, which also advances to the next screen in the menu tree. Pressing the softkey labeled ‘NEXT’ or ‘PREVIOUS’ will abort loading the parameters into memory, and advance to the appropriate screen. In cases where there is a single parameter shown on a screen, pressing the softkey labeled with the desired value will immediately load the parameter into memory. In this case, the parameter load can be aborted by pressing the CLEAR key, which will return to the previous screen, or by pressing the softkey labeled ‘NEXT’, which will advance to the next screen in the menu tree and so on.

3.5.2.2 Moving to the Next Screen in a Menu Tree If the user desires to advance to the next screen in the menu tree, the softkey labeled ‘NEXT’

should be pressed. Some submenu screens can only return to a previous screen, in this case a softkey will be labeled ‘RETU RN’. In either case, if any numerical parameters are being edited, the values will not be loaded into memory. When the last screen of a menu tree is reached, advancing to the next screen will wrap to the first screen of the menu tree.

3.5.2.3 Moving to the Previous Screen in a Menu Tree

If the user desires to advance to the previous screen in the menu tree, the CLEAR key should be pressed. If any numerical parameters are being edited, the values will not be loaded into memory. If the clear key is pressed while the first screen of a menu tree is displayed, the previous screen will wrap to the last screen in the menu tree.

3.6 Summary of Basic Front Panel Controls

Shown below is a table describing the functionality of the front panel keyboard in relation to front panel control:

ENTER Loads edited values into memory and advances to next screen in the menu tree. CLEAR Aborts loading values into memory and moves to the previous screen in the menu tree. NEXT

Aborts loading values into memory and moves to the next screen in the menu tree.

(softkey) PREVIOUS

Aborts loading values into memory and moves to the previous screen in the menu tree.

(softkey) Numeric Keys Used to edit numeric parameters.

3.7 DMD10 Modem Strap Codes (Quick Set Keys)

The Strap Code is a quick set key that conveniently sets many of the modem parameters. For quick setup of the DMD10, Strap Codes are very helpful. When a Strap Code is entered,

TM058 - Rev. 2.3

the modem will be configured for the code’s corresponding data rate, overhead, code rate, framing, scrambler type and modulation. Refer to Table 3-2 below for a listing of the available RCS10 Strap Codes.

NOTE: The Strap Codes are only used to configure the Modems with the predefined settings. It might be necessary to reconfigure the Modem’s associated I/O Card, Overhead, Interface type etc., for the system to operate properly.
