1 General Information

1.1 Introduction

The ATS-6511 is a state-of-the-art signal distribution system providing GPS disciplined time and frequency references when locked to an ATS-6501. It utilizes an internal Ovenized Crystal Oscillator (OCXO) and low noise synthesizer (LNS) in conjunction with fiber optic inputs from an ATS-6501 to provide outputs that are characterized by the short-term stability of the OCXO, medium term stability of the ATS-6501 internal Rubidium reference and the long-term stability of the GPS constellation and/or and external Cesium reference. This provides a scalable architecture that allows users to fulfill a wide range of current and future requirements with a single unit. The ATS-6511 is suitable for a variety of precise time and frequency applications. Additionally, the ATS-6511B provides the user with the capability to enhance the frequency stability and holdover performance of the unit by using an external cesium (Cs) clock as the reference. An internal rubidium option is also available in the ATS-6511B-R.

In applications where reliability is a must the ATS-6511 is capable of operating from an AC (100 – 240VAC, 50-60 Hz) or DC Power -48 VDC (SELV type) (-18 to -60 VDC) source and comes with two fully redundant power supplies. The unit is capable of operating from a single supply in the event one of the two power supplies fails.

1.2 Ordering Information

ATS-6511A: Standard dual fiber input time and frequency distribution chassis. Dual AC input supplies included. Requires an external fiber time and frequency reference and includes two 1 PPS/DC IRIG, one 10 MHz, and one AM IRIG output module.

ATS-6511B: Long term holdover capability dual fiber input time and frequency distribution chassis. Dual AC input supplies included. Requires an external fiber time and frequency reference and includes two 1 PPS/DC IRIG, one 10 MHz, and one AM IRIG output module. A rear panel BNC connector is included for an external holdover reference, for instance a Cesium. The R option is available to provide an internal Rubidium for holdover.

ATS-6511C: Improved Phase Noise and Allan Deviation performance for the 1, 5, 10Mhz outputs. All other features equivalent to the ATS 6511B.

Option D (DC Power Input): Provides DC input -48 VDC (SELV type) (-18 to -60 VDC) capability instead of AC for one of the supplies. The second power supply is still AC.

Option D2 (Dual DC Power Input): Provides dual DC input -48 VDC (SELV type) (-18 to -60 VDC) capability instead of AC.

2 Installation

The ATS-6511 provides a number of features which may require additional setup and this section provides a guideline for the basic setup. After completing this section, the ATS-6511 will produce timing outputs to the coarse calibration accuracies specified in Appendix A. The ATS6511 is designed to be quickly and easily integrated with other system components. Just a few steps are required in setting up the system so that it will begin producing accurate timing outputs. In order to set the system up, users will need to power up the system and set up communications in order to have access to the system command port. The only inputs required for operation of the ATS-6511 are at least one power source and one fiber optic input sourced from a 4372A/4372A-T installed in an ATS-6501 with revision 3.6.3 or newer software.

2.1 Powering on the ATS-6511

Apply power to the system by supplying input power to at least one of the two power supplies. When power is applied to the ATS-6511 the front panel will go through a self test and then the ATS-6511 will begin booting up.

Note: If power is applied to both power supplies the Status Indicator on the front panel of both power supplies should be green. If power is applied to only one of the two supplies the power supply without input power should have a red Status Indicator and the unit’s Alarm Indicator should be red.

Note: The ATS-6511 front panel Power-On Self Test (POST) will occur even if the front panel software flash is removed.

A. The Date/Time display will sequentially test each segment on each individual position

within the display.

B. One at a time, each position of the display will display the number 8 starting from the far

left and working to the right.

C. Each LED below the Date/Time Display (Alarm, Oscillator Locked, Input A, Input B, &

Outputs Enabled) will be turned on one at a time starting from the left to right. As each LED is tested it will be green, then red, and then turn off with the exception of the Input A indicator, this indicator will turn red, then green, then off.

D. The Date/Time display will then display “-9876543210” on the front panel. E. Lastly the Date/Time display will have a “-“ in the center of each position in the display. F. While the ATS-6511 is booting up and waiting for the internal oscillator to lock the Osc

Lock, Input A, and Input B LED indicators on the front panel below the Date/Time display should be Red and the bars in the display after the POST will move to the top, then center, then bottom and then go out. This display will repeat cycling the bars on the Date/Time display as long as the unit is not tracking one of the input fiber signals. Once the unit obtains the date/time from the fiber input (A or B) the Input A and/or Input B LED will turn green, the Osc Lock light should turn green, the front panel will begin displaying the present Date/Time, and the Outputs Enabled indicator will turn green within ~2 minutes.

Note: As the ATS-6511 warms up, the Oscillator Lock indicator should turn green within ~5 minutes after the system is turned on and the system locks to one of the Fiber inputs. The Alarm light may stay on until the Outputs are enabled. This is normal and does not indicate there is a problem with the unit. When the unit has locked the OCXO to one of the fiber inputs, the outputs will be enabled and the Outputs Enabled LED will turn green within ~2 minutes.

2.2 Communicating with the ATS-6511

Operators are capable of communicating with the system through a LAN connection directly or via one of the USB Ports when using (ATS 94000-115200) USB to Serial cable to access the command port.

2.2.1 DHCP

The ATS-6511 runs DHCP by default and will be assigned an IP address if it is connected to a network with a DHCP server. The ATS- 6511 will display the current IP address assigned to the unit in the Date/Time display after pressing and releasing the Display pushbutton on the front panel. Users can use this IP Address to access the systems command port (1700).

Note: If the LAN Cable is not connected to the unit an IP Address is not assigned and the front panel display button will not display an IP address for the system. Once the LAN cable is connected to the unit it will automatically attempt to obtain an IP address from a DHCP Server. If this does not work you may need to power cycle the unit.

2.2.2 Static IP Addresses

If you require a Static IP Address there are two options to set the network information in the system.

2.2.2.1 Network

If the network has a DCHP Server you can obtain the IP Address (ip addr) by pressing and releasing the Display pushbutton on the front panel. Telnet into the system using telnet ip addr

1700. Once the “ATS-6511>” prompt is displayed use the network_config command to manually configure the IP address for the unit. (See section 2.2.3).

If the network does not have a DHCP Server, press and hold the front panel display pushbutton for ~10 seconds until the display shows the IP Address of 192.168.0.1. This temporarily sets the IP Address of the unit. Telnet into the system using telnet 192.168.0.1 1700. Once the “ATS6511>” prompt is displayed use the network_config command to manually configure the IP address for the unit. (See section 2.2.3).

Note: If the LAN Cable is removed from the unit and reconnected the unit will attempt to obtain an IP Address from the DHCP Server. If the default IP Address (192.168.0.1) was set it may get reset. Press the Display Button on the front panel to make sure the IP Address is still set, if not press and hold the button until the default IP Address is set again.

2.2.2.2 Console Cable

This feature allows local users to set the unit up without having to access the system via the network. Connect a terminal to one of the USB ports on the rear panel using the USB to Serial conversion cable (ATS 94000-115200). Changes can be made using any terminal program (e.g., HyperTerm, TeraTerm) from the serial port of a computer/terminal. The communication settings are 115200 Baud, No Parity, 8 Data Bits, and 1 Stop Bit. Once connectivity is established the user will see the ATS-6511> command prompt. Execute the network_config command to set the IP Address, Netmask, Broadcast IP, and/or Default Gateway for the system if you are using a static IP Address. (See section 2.2.3).

ATS-6511A/B/C Users Guide

DOC 6511_Release K

Note: Make sure the USB Console Cable (ATS 94000-115200) is installed in one of the two USB ports when the system is powered on. If not, power the system down, plug the cable in and re-apply power.

Caution: The system default settings allows the operator to set a default IP address by pressing and holding the Display pushbutton on the front panel for ~10 seconds. This will set the IP address to 192.168.0.1. The IP address will be displayed on the front panel after it is set. If the button is held down too long and the IP Address is set to the default by mistake, you may be able to clear this by pulling the LAN connection on the rear panel and plugging the connector back in. If not, power-cycle the unit to restore the proper network settings. This front panel IP reset feature can be disabled using the frontpanel_button command. Users are cautioned that this reset feature is ON by default and must be turned off if this is not the desired behavior.

2.2.3 Setting an IP Address

Use the following steps to set the IP Address on the ATS-6511.

A. Telnet into the system telnet ip addr 1700 or connect to the unit via the (ATS 94000-

115200) USB Console Cable and the ATS-6511> prompt should appear.

B. Use the network_config command and options to set the system to the desired network

settings.

network_config --mode <DHCP|static> --ip <ip addr> --mask <mask> --broadcast <broadcast> -gateway <gateway>]

[Example]

network_config --mode static --ip 192.168.1.50 --mask 255.255.255.0 --broadcast 192.168.1.255

--gateway 192.168.1.1

C. These network settings will take effect immediately. Users should see the following:

<working> ………..

D. Users connected via the network will need to reconnect to the system using the newly

assigned static IP Address. Users do not need to save these changes; they are automatically stored on the system. The ATS-6511 will start up with the new settings each time it is rebooted or power cycled.

E. Users can also view the current network settings using the network command. This will

display the current settings.

ATS-6511>network

[mode] static [static] [broadcast] 192.168.150.255 [default_gateway] 102.168.150.1 [ip] 192.168.150.85 [netmask] 255.255.255.0 [OK] 2013-08-13T14:11:12Z

Once timed out, the connection will drop.

2.2.4 Firewall Settings

The system IP firewall has a default “allow all” policy. To enable the firewall, the customer needs to create a firewall rules file on the product file system named /mod/tsc/firewall.rules. There are example firewall rules files on the product in the directory /usr/tsc/site/firewall. Example rules files may be copied to the correct location and edited on the product using ‘vi’. Once the rules file is setup, reboot the product.

Note that miss-configuration of the firewall can lock out network access to the product. If that occurs, the firewall may be disabled by using a USB command port adapter, and executing the command firewall --disable. This removes the current firewall rules and resets it to immediately allow all traffic exposing the device.

The firewall is the standard FreeBSD IPFW. Full documentation on the firewall configuration may be found here:

http://www.freebsd.org/doc/en/books/handbook/firewalls-ipfw.html

2.2.5 USB Ports

The USB ports on the rear panel allow:

• Users to access the command port (ATS 94000-115200). See section 2.2.2.2. Users

can set the IP Address on the box following the instructions on section 2.2.3.B-C. The system will automatically connect to the command port and provide the ATS6511> command prompt.

• The ATS-6511B to communicate with a 5071A Cesium Clock (ATS 94001-5071A).

See section 2.7.

2.3 ATS-6511 Installation

The ATS-6511 is ready for installation into a standard 19" (48.3 cm) rack using either slides or shelves and will take up 1U of rack space. The C-300-S Series rack slides from General Devices or equivalent slides are recommended.

CAUTION: Use the screws provided with the unit to mount the rails to the side of the chassis. If longer screws are used, you could damage the power supplies or prevent them from being removed from the chassis.

2.4 ATS-6511 Modules

2.4.1 Power Supplies

The ATS-6511 operates with two power supplies capable of operating on different power sources. The 4385A (AC Power Supply) and 4386A (DC Power Supply) are available. The ATS-6511 is capable of operating on one power supply in the event the other fails or its input source fails. Power Supply #1 is on the left and Power Supply #2 is on the right. See Appendix A for the specifications on the Power Supplies.

ATS-6511A/B/C Users Guide

DOC 6511_Release K

2.4.2 Output Cards

The ATS-6511 has the capability using six output cards in each unit. The cards slots are identified by number so the operator is capable of determining the slot of the card in the show command and identifying the cards physical location in the chassis. Figure 1 shows the rear panel layout of the unit from left to right.

Slot 1 Slot 3 Slot 5 Slot 2 Slot 4 Slot 6

Figure 1 Rear Panel Output Card Locations

The ATS-6511 will operate with six different types of output cards. All output cards except the 4399A can be operated in any of the six slots. The 4399A is a double wide module that can only be installed in slots 3 and 5. The divider between Slots 3 and Slot 5 must be removed to accommodate installation of the 4399A L-Band module. To remove this divider, remove modules that are installed in these slots. Remove the screw located on the top of this divider. After removing this screw, pull the divider out the back of the chassis and install the 4399 Card. Once the card is installed power cycle the unit to allow the system to start up with the current card configuration.

At start up the unit will automatically detect and configure the system based on the cards installed. The cards are also hot swappable. Each of the standard output cards has four output connectors with the output number identified as shown below in Figure 2. See Appendix A for the specifications of each output module.

2.4.2.1 4394A (PPS/DC IRIG)

The factory default for this module provides two 1PPS outputs and two DC IRIG (B000) Outputs. The default configuration sets Outputs 1 and 2 to 1PPS and Outputs 3 and 4 to DC IRIG. The output types are user selectable/programmable. Users can change the signal types (PPS/DC IRIG), the PPS signal parameters, and the IRIG signal types on individual output ports.

• PPS: Valid PPS settings are 1, 10, 100, 1K, 10K, 100K, 1M PPS and 10M PPS. To set the PPS signal parameters use the pps command:

ATS-6511> pps [slot#] [port#] [pulse period] [pulse width]

Figure 2 Single Slot Output Module

ATS-6511A/B/C Users Guide

DOC 6511_Release K

The following example sets the PPS on Slot 1, Port 2 to 1MPPS and the pulse width to 500nsec (1/2 the duty cycle).

ATS-6511>pps 1 2 1e-6 5e-7

The following rules apply:

1. PERIOD - period of pulse in seconds(max of 1, min of 1e-7)

2. WIDTH - pulse width in seconds (minimum of 5e-8)

3. For PPS Rates where the duty cycle is 10 µ s or greater the pulse_width must be a

multiple of 10 µs, at least 10 µs wide, and at most half the duty cycle of the pulse_period.

4. For PPS rates where half the duty cycle is less than 10 µ s, the pulse_width must be

exactly one-half the pulse_period. (See example above.)

The system will generate an error message if the values are not correct or entered improperly.

To verify the settings use the settings hardware:slots:N command (N=Slot #) to obtain the current settings for a particular card.

2.4.2.6 4399A (L-Band BPSK module)

This module provides four RF outputs and one 1 PPS output on SMA connectors and is controlled via the 9 pin RS-232 located on its panel. The 4399A serial interface is via RS-232, at 115200 baud, 8-N-1, with flow control set to “none”. The serial interface is the means for issuing commands to the module as well as sending the file containing the BPSK bit pattern. Commands are case-sensitive. The BPSK bit pattern file can be sent to the board using Hyperterminal or any other communications program that supports the XMODEM protocol.

To send the bit pattern file using Hyperterminal, follow these instructions:

ATS-6511A/B/C Users Guide

DOC 6511_Release K

1.) Type “sendfile <ENTER>” at the terminal. The unit will then initiate erasure of the

on-board flash. This erasure process will take approximately 1 minute.

2.) Once erasure is complete, the terminal will prompt “send file.” The device will then

send an initiate character to the terminal once every 10 seconds until the file is sent. (NOTE: this process can be aborted by typing “Ctrl-C <ENTER> <ENTER>” but the flash will remain empty.)

3.) To send the file, select “Transfer” from the menu bar, followed by “Send File…”.

4.) Browse to the bit pattern file desired, and then select “Xmodem” from the Protocol

list.

5.) Click “Send”. The file will then be transferred to the device.

6.) Once transmission is complete, the Xmodem transfer window will close and the

device will send a termination character to the terminal once per second.

7.) Type “<ENTER> <ENTER>” to exit the transfer routine.

4399A Commands:

Note: The following commands are case-sensitive.

deviceid: reads and returns the rev number of the board.

sendfile: erases the flash memory and waits for the input of a new BPSK file. The BPSK file is

transmitted via XMODEM. If a BPSK signal is running when this command is issued, the signal output will be stopped.

freq: used to set the carrier frequency of the BPSK signal. After “freq <ENTER>” is typed, the terminal will prompt for the frequency. Frequency is entered in MHz, in hexadecimal format (i.e. 1500 MHz will be entered as “5DC”). Valid frequencies are 900 MHz – 1175 MHz, 1225 MHz – 1575 MHz, and 1625 MHz – 1750 MHz.

chiprate: used to set the rate at which the BPSK bits are transmitted. After “chiprate <ENTER>” is typed, the terminal will prompt for the chip rate. Chip rate is entered in MCPS, in hexadecimal format (i.e. 10 MCPS will be entered as “a”, and 20 MCPS will be entered as “14”). Valid chip rates are 1 MCPS – 20 MCPS.

run: used to reinitialize the signal output with the current frequency and chip rate settings.

stop: used to disable the signal output.

The following is a sample instruction set to initialize and run the 4399A unit at a frequency of 1 GHz, with a chip rate of 16 MCPS:

Welcome. 4399A> freq Enter freq>3e8 Done. 4399A> chiprate Enter rate>10 Done. 4399A> run

ATS-6511A/B/C Users Guide

DOC 6511_Release K

Done.

4399A BPSK File Format:

The BPSK file is sent to the 4399A unit through the serial port, via XMODEM. The file to be sent must be in binary format, with the first 32 bits designating the full length of the file. The BPSK signal may then begin on the 33rd bit and continue to the end of the file. This means that the BPSK file for a 10,000,000-chip pattern will actually be 10,000,032 bits long, and therefore the first 32 bits of the file must read 009896A0 (when viewed with a hex editor).

This device is designed to utilize chip patterns in 1,000,000-chip increments in size, but can accommodate any chip size that is divisible by 16. Maximum capacity of the internal flash memory is 32 megabits. When sending an output, the 4399A will continuously repeat the entire bit pattern in sequential order, from bit 33 to the end. Using this format, “1” represents the carrier signal and “0” represents the carrier signal after a 180 degree phase shift.

A very short sample of a 64-bit BPSK pattern follows:

00000060 D1CAEF91 3134E17C

This will cause the unit to continuously repeat the following pattern:

1101 0001 1100 1010 1110 1111 1001 0001 0011 0001 0011 0100 1110 0001 0111 1100

2.5 Fiber Optic Input Behavior

The ATS-6511 does not have a front panel switch to select the desired Fiber Input. This is accomplished via the auto switching feature or the command port. The default setting has Input A as the primary input, the Auto-Switching feature enabled, the minimum time for the primary source to be valid is 60 seconds, and the rearm feature is on. Once the ATS-6501s are operating and their outputs are enabled they will send the reference signals via fiber to the ATS-6511(s). One ATS-6501 drives Input A, a redundant ATS-6501 drives Input B. The ATS-6511 will select Input A once that fiber pair comes on line and the system locks to it since it is the default input.

Once the ATS-6511 is operating and both fiber inputs are present the unit will monitor the fiber inputs. The fiber pair driving the ATS-6511 is displayed on the front panel; Input A or Input B will be ON and Green. The status input:switch command will indicate the switching mode and the selected fiber pair. (i.e. Auto Switch: A). The alternate source input will also indicate the status of the fiber and if the signal is present and it will flash Green (On for 1 second, off for three seconds). If neither fiber input is available, the ATS-6511B or C will enter holdover mode using the internal Rubidium (ATS-6511B-FR or ATS-6511C-FR option) if available, the external reference input if available (ATS-6511B or C), or the internal OCXO (ATS-6511A, B or C).

2.5.1 Auto-Switching

When enabled, one of the two fiber pairs (A or B) will be the primary source. System settings can be checked using the settings fiber:switching command.

The mode indicates the ATS-6511 is using the auto switching feature. If there is a loss of signal on Fiber A (master) the Input A indicator will turn RED to indicate there is an issue with that source and the system will automatically switch over to Input B and the Input B indicator will turn ON. The status input:switch command will indicate an auto switch occurred as well as which fiber is currently selected (i.e. Auto Switched: B (now in B after an autoswitch). Once the signals to Input A are restored the INPUT A indicator will flash Green (on for 1 second/off for three seconds). When the master source (in this case Input A) remains valid for the [min_valid_time] (seconds-in this case 60) and the [auto_rearm] is true, the ATS-6511 will automatically switch back to the master source, in this case Input A becomes the active channel.

Note: If the [auto_rearm] is false, the system will remain on Input B until the operator commands the system to return to Input A. Once Input A is restored the Input A indicator will flash Green (on for 1 second/off for three seconds) and the system will remain in this mode until the operator commands the system to switch back to A. (fiber_switching auto A 60)

Caution: The system will not switch back to the primary source unless the manual option is used or until the [min_valid_time] has expired if you are using the auto mode with the norearm option off.

If there is a loss of signal on Input B (the alternate source) the INPUT B indicator will turn RED to indicate which fiber pair has been lost. Once the signals are restored the INPUT B indicator will flash Green indicating the source is available.

When both fiber inputs are not available, the unit will enter holdover mode. In the ATS-6511A, the internal OCXO is the holdover reference. The ATS-6511B-R provides an internal Rubidium reference for holdover, or can use the 10 MHz provided to the rear panel as the holdover reference. The ATS-6511B provides the user the ability to use an external input for holdover in addition to the internal OCXO.

2.5.2 Manual Switching

When the auto switching feature is disabled the operator must select the desired input (A or B) as the primary (master) source, in the example below Fiber A is the master. System settings can be checked using the settings fiber:switching command.

The mode indicates the ATS-6511 is using the manual feature. In this case the Input A indicator will be On and Green to indicate the system is locked to the primary (master) source. The Input B indicator will flash RED (on 1 second/off three seconds) to indicate the source is available and the system is in the manual switching mode.

If there is a loss of signal on Fiber A the Input A indicator will turn RED to indicate there is an issue with that source however the system will not automatically switch over to Input B. The Alarm Indicator will turn RED and the Oscillator Lock Indicator will go out indicating the system is free running on the internal clock. Once Input A is restored the Input A indicator will flash RED (on 1 second/off three seconds) to indicate the source is available. Once the ATS-6511 locks to the reference signal on Fiber A input the Input A indicator and the Oscillator Lock Indicator will turn Green and the Alarm Indicator will go out.

The indications for Input B will not change unless the ATS-6511 is commanded to use Input B (fiber_switching manual B) or the input signal to Fiber B is Lost. Once this occurs the Input B indicator will turn Green and the Oscillator Lock Indicator should come on within a few seconds. After this the Alarm indicator should go out. The system will remain on Input B until commanded otherwise. Once the signals are restored The Input A indicator will flash RED (on 1 second/off three seconds) to indicate the source is available and the system is in the manual switching mode. The Fiber B indicator will turn RED and remain on if the input signal is lost.

2.6 Fiber Modes/Calibration

The ATS-6501/6511 systems are capable of operating in three distinct modes. This section assumes the on-time-point (OTP) of the system is the rear panel outputs on the ATS-6511. This may not be the desired location for the OTP; users should refer to section 2.7 for information on changing the location of the OTP for the system.

Warning: Users are cautioned to set the system (ATS-6501, TSC 4340A, and ATS 6511A/B/C) up in the desired operational configuration and calibrate any ATS-6511s in the two_way_disabled fiber mode to ensure the 1PPS outputs are either known or compensated for as described below. Changes to the system configuration will likely require re-calibration. If you have questions contact Symmetricom.

2.6.1 Two Way Mode (ATS-6501 with 4372A-T Fiber Card)

This mode uses the data exchange between the ATS-6501 4372A-T (Two-Way fiber card) and the fiber A/B input on the ATS-6511 to calibrate the output of the ATS-6511 and set the system on-time point (OTP) to the rear panel of the ATS-6511. The fiber path may pass through a TSC4340A. This method provides three distinct advantages. 1) The delays between the 6501 and 6511 are constantly measured and the system will compensate for any changes (i.e. diurnal changes with or without a 4340A). 2) The pair of fibers for Input A and Input B do not have to be the same length and could take separate paths. 3) The system calibration is automatically done for each pair of fiber inputs as long as the fibers for that pair are of equal length. If the individual fibers used in the pair paths to Input A or B are different length, the path length difference between the two fibers must be determined and the fiber delay difference programmed in for each input (A and/or B).

Note: Refer to Section 2.6.4 to properly calibrate the system. Also note this is NOT the same as the legacy mode of operation. The ATS-6511 will not lock to the fiber input if the ATS-6501 has a 4372A Card and you are operating the ATS-6511 in the two-way_disabled fiber_mode.

2.6.3 One-Way Fiber Calibration

For system applications requiring the highest level of accuracy, the system should be calibrated at Symmetricom. This process involves installing the ATS-6501, user’s antenna and antenna cable, ATS-6511 and fiber optic cable(s) at the factory and comparing the PPS outputs to a system which has a known offset to UTC(USNO). Once the calibration is complete, the delay values are provided to the customer when the system is delivered. The PPS outputs will be accurate to the precise calibration levels specified in Appendix A as long as the user installs the antenna at a surveyed location. If a surveyed antenna location is not available, the ATS-6501 can be used to survey the location. Refer to the ATS-6501 manual for more information on installing the ATS6501 and antenna(s).

A coarse calibration of an ATS-6511 in a system is accomplished by accounting for the individual system delays and combining them to determine the overall delay of the system. This method is generally less accurate because the individual delays in the system are estimated and may not be entirely accurate. Refer to the ATS-6501 manual for more information on calculating the delay of the ATS-6501. Equation 2-1 gives the general formula for performing a coarse calibration of the cabling to the ATS-6511.

f_Measure)per_unit_oefraction(Index_of_rFiber*Length_of_onds)_Delay(ATS_

Eq. 2-1

ATS-6511A/B/C Users Guide

DOC 6511_Release K

The Index_of_refraction refers to the velocity of the fiber optic signal as it travels through the fiber. This information can be obtained from the manufacturer of the fiber. It is typically specified as the delay value based on a unit of measure. Use the value provided and if needed convert the fiber optic cable length to the correct unit of measurement and calculate the delay as shown in Equation 2-1.

Once the ATS-6511 delay has been calculated, it must be entered into the system using the fiber_delay command. The example below is using a delay value of 118.5 ns for both fibers. Once the fiber delay value has been properly set use the save command to save the current delay to ensure the system uses the correct delay value after a reboot or power cycle. Users can verify the value was set properly by using the settings fiber:delay command and reviewing the settings.

Note: The new delay value will take effect immediately and could cause an alarm if the delay value forces the 1 PPS offset to be larger than 100 ns. The system will steer the internal clock to remove the fiber delay, if the alarm light came on it will go out once the 1 PPS Value returns to within 100 ns. The ATS-6511 outputs will now be accurate to the fine calibration accuracy specified in Appendix A.

2.6.4 Asymmetrical Fiber Paths To a ATS 6511 Input Channel

Two way mode can still be used in systems with asymmetrical transmit and receive fiber paths to a particular ATS 6511 input channel. The difference in delay between the two paths must be determined and entered into the ATS 6511 settings. The delay difference can be determined by using an optical TDR, or measuring the 1 PPS offset between the ATS 6501 and ATS 6511 using each of the fibers in two_way_disabled mode. When using the OTDR subtract the ATS 6511 to ATS 6501 transmit path delay from the ATS 6501 to ATS 6511 transmit delay path to obtain the fiber delay differential. Enter this number, including the sign, using the fiber_delay_diff command.

2.6.5 TSC-4340A

The 4340A fiber distribution amplifier may be used to distribute one fiber connection from the 4372A or 4372A-T to up to eight ATS 6511A/Bs. The 4340A works in any ATS 6511 fiber mode. Ensure you match fiber types when designing and installing a system which will include a 4340A. If using single mode 4372A or 4372A-T (default for both) ensure you are using a single mode 4340A (4340AS-8S for example). All of the systems are also capable of operating using multi-mode fiber by simply replacing the SM SFPs in the units.

2.7 Setting the System On Time Point (OTP)

The OTP of a system is defined as the point at which the timing signals coincide with UTC(USNO). Typical systems use distribution amplifiers and cabling to distribute timing signals from a single source to multiple users. This distribution network will delay the timing signals and affect their accuracy. For this reason it is important to select an appropriate OTP so that the desired timing signals are accurate when they reach the user.

Section 2.6 describes calibrating the ATS-6511 in both the two-way and one-way modes assuming that the OTP of the system is the rear panel of the ATS-6511. This is not generally a convenient location for the OTP of the system because there will be a delay associated with the distribution of the signals to the user. Figure 3 illustrates how to move the OTP of the system from the rear panel of the ATS-6511 to the user inputs. In moving the OTP of the system it is imperative that the distribution delays from the ATS-6511 to each of the users is equal. This will ensure that all users receive accurate timing signals.

Once the delay of the distribution network is known the OTP of the system can be shifted from the output of the ATS-6511 to the input of the user equipment. Use the dist_delay command to enter the delay value between the rear panel and desired OTP location as shown in Figure 3-2. Installing cables and distribution with the same delays will also ensure the 10 MHz signals are in phase, and the rising edge is aligned with the 1 PPS signals. The example below shows a delay of 50nSec.

2.8 Using an External Frequency Reference (ATS-6511B or C)

Users may decide to provide an EXTERNAL frequency reference to the ATS-6511B or C. The external frequency reference may be monitored by the ATS-6511B or C via a RS232 connection through either of the USB Connectors on the rear of the unit (ATS 94001-5071A). The Symmetricom 5071A is currently the only model supported; users should contact Symmetricom about the possibility of utilizing other clocks. The 5071A communications settings must be set to 9600 Baud, No Parity, 8 Data Bits, and 1 Stop Bit (9600,N,8,1) and a null modem serial cable will be required.

WARNING: Prior to setting the reference to external ensure the 10MHz signal from the reference is connected to the 10MHz IN connector on the rear of the ATS-6511B or C. If not, the ATS-6511B or C outputs will not be within specification and it could take up to several hours for the system to begin providing outputs within their specifications.

Note: Make sure the USB-to-Serial Converter (ATS 94001-5071A) is installed on one of the two USB ports when the system is powered on. If not, power the system down, plug the cable in and re-apply power. The USB/Serial Cables are programmed to communicate with an external reference (ATS 94001-5071A) or to provide users access to the command port (ATS 94000-

115200). These cables are NOT interchangeable.

To set the type of reference use the reference_type command. If users are operating with a Symmetricom 5071A and they will set the system up so the ATS-6511B is communicating with the 5071A select hp5071A, if not select cesium.

If these settings are correct type save to save the proper reference and reference type in the default user configuration file on the system to ensure the system starts up properly after a reboot or power cycle.

2.9 System Configuration Files (Syscfg)

The system is capable of allowing users to monitor and verify system configurations using the syscfg command. The files can be set up so critical system parameters can be checked against user defined nominal values and when the system settings do not match the nominal values the system provides a user defined alarm string to describe the configuration mismatch. This applies to any data set the system generates on Port 1900. Users can define the field and the nominal value. Users are cautioned that these values reported on Port 1900 are checked and must exactly match the value in the syscfg file. As an example, if you are operating in the dymanic positioning mode you would not want to set a nominal value for the altitude, latitude or longitude. You can however set the nominal value to “dynamic” for the positioning mode to alert you if someone places the unit in the incorrect positioning mode.

By default the system is operating in the “Standalone” mode and in this mode these parameters are not checked against the information provided on Port 1900. To enable this feature users will need to set the nominal values in the /mod/tsc/syslog/localcfg.py file. If no user specific parameters are set the system will use the factory default file /usr/tsc/syscfg/syscfg_default.py. Once the settings are entered users can turn this feature on using the syscfg command. See Appendix D for examples.

3 Operations

The ATS-6511 is used to extend the timing signals provided by the ATS-6501 over fiber optic cabling to accommodate transmission over long distance and improve signal integrity.

3.1 Front Panel

The ATS-6511 has several front panel indicators to provide the operator with the overall status of the unit and will provide a visual alarm indication if a problem with the hardware or the unit detects a condition that would cause the output signals to be outside of their timing specifications. More detailed status information can be retrieved using the status command on the Command Port.

Figure 5 ATS-6511 Front Panel

3.1.1 Power Supply Indicators

Each power supply has a front panel indicator that provides the operator an instant visual indication of the supply status. Power Supply #1 is on the left, power supply #2 is on the right as viewed from the front.

Indicator Status

The active line will display false when the fans are functioning normally and true for one or both fans if they are not. If a fan is having issues you will see the number of occurrences increment up from 0 as each event occurs.

3.1.6. Flash Card

This card contains the operating system software, application, and user settings for the system.

3.1.7. Display Button

When pressed and released, this button will display the ATS-6511’s current IP Address if the address has been set through DHCP or statically. If the system is set up to use DHCP and it was unable to obtain an IP Address the system will set the IP Address to 0.0.0.0 and the system will not display an IP Address on the front panel when this button is pressed.

The second feature of this button is enabled by default. If this button is held down for ~10 seconds it will set the IP Address on the system to 192.168.0.1. This is a temporary setting and it will not survive a system reboot or power cycle. This feature can be disabled using the frontpanel_button command and setting the value to 0. Once set the value can be confirmed using the settings hardware command. Make sure to save the system settings.

3.2 Rear Panel

All hardware interfaces and connectors are located on the rear panel of the ATS-6511. The system can provide eight types of timing signals: 1 PPS, 10 MHz, 5MHz, 1MHz, DC IRIG, AM IRIG, NASA36 and L-Band BPSK depending on which output modules are installed and the system configuration settings. All output modules except the L-Band module have four BNC(F) connectors. The L-Band module has four RF outputs and one 1 PPS output on SMA(F) connectors (shown in slots 3 and 5 below). These outputs can be used to directly feed other instruments or feed a distribution system that provides any number of user outputs. The on-timepoint (OTP) of the system is typically at the output of the BNC connectors (Section 2.6) but it can be adjusted to be any point in an integrated system by accounting for distribution delays and adjusting the fiber delay value (Section 2.7).

ATS-6511A/B/C Users Guide

DOC 6511_Release K

Figure 6

ATS-6511A Rear Panel

The only inputs required for operation of the ATS-6511 are at least one power source and one fiber optic cable sourced from a 4372A (3.6.3 or newer) or 4372A-T (4.0.0 or newer) installed in an ATS-6501. Once the outputs are enabled, the unit will continue to output timing signals even when the fiber optic cable is removed. However, the accuracy of these outputs will degrade over time at a rate much faster than the ATS-6501 as the standard ATS-6511 has an OCXO whereas the ATS-6501 contains a Rubidium for holdover. The ATS-6511B and C has the option for an internal Rubidium or an external frequency reference (i.e. a Cesium) to improve holdover. For redundancy, a second fiber optic cable can be connected to the rear panel. This fiber should be sourced from a 4372A or 4372A-T in a different ATS-6501 chassis.

Connection to a local area network (LAN) is supported by the ATS-6511. This allows users to access the unit remotely and also provides error monitoring capabilities. The USB ports can be used in conjunction with a USB-to-Serial conversion cable (ATS 94000-115200) to allow users access to the command port via a local terminal.

ATS-6511A/B/C Users Guide

DOC 6511_Release K

significant software/firmware changes that necessitate this update be done by completely replacing the flash card. Please refer to the software release notes to accomplish this update.

3.3.2.1 Flash Card Replacement

This requires removing the currently installed flash disk and installing a new one which has the updated software. Power the system down, press and release the SD card located in the SD Card slot on the front panel. Remove the current flash disk and replace it with the new flash. Once the new flash is securely installed restore power to the unit.

Caution: The system network and user configuration settings are NOT saved and the system will need to be completely set up with the network and system settings.

4. Once the update is complete the system will automatically reboot. Local users will

see the front panel display lock up for ~2 minutes. After this the system will begin launching the application and local users will see the typical boot process where the bars repeatedly start off at the top, move to the middle, then bottom, then go out. The application start up will take ~2 minutes. Once the oscillator lock light is on it should take about 5 minutes to steer the OCXO on frequency and phase, and enable outputs.

Note: Users can obtain the new software image and software release notes from Symmetricom

ftp://ftp.timing.com/pub/ATS-6511. Refer to the software release notes for specific instructions

related to a particular revision of software. If the software update is not applied after transferring the image to the unit and the unit is power cycled users will need to upload the .iso file again in order to update the system software.

Warning: Users upgrading from software versions prior to Version 3.9.X will NOT be able to use this command to update the software. This will require replacing the front panel flash card.

ATS-6511A/B/C Users Guide

DOC 6511_Release K

Caution: If the software update is not applied and the unit is power cycled users will need to upload the .iso file again in order to update the system software. The .iso file will be wiped from the system since it is held in volatile memory.

3.3.3 Declassifying the System

Some users may require that the ATS-6511 be declassified before shipping the system to a new location. Doing this involves removing all non-volatile memory from the unit. Power the system down and press lightly on the SD Card in the slot on the front panel. This will release the SD Card. Simply remove the flash disk from the front panel. The flash disk must be destroyed per the user’s standard security procedures. A new flash disk can be obtained from Symmetricom.

3.4 User Interfaces

Software interfaces on the ATS-6511 are limited in their ability to provide users with real-time control. Adjusting some system parameters during operation of the ATS-6511 can seriously impact the timing performance of the unit and therefore the ability to adjust these parameters is limited by the software. Once properly installed, the ATS-6511 serves as a stand-alone device which requires little to no interaction. Remote error monitoring capabilities are provided as a means to ensure that the unit is powered and operating properly.

3.4.1 Operating System

The ATS-6511 operates a Symmetricom modified version of FreeBSD. FreeBSD is a Berkeley derivative of the UNIX operating system.

3.4.2 Telnet

One advantage of accessing the ATS-6511 via telnet is that multiple telnet sessions may be active at once. It is recommended that users connect directly to the desired port based on the function(s) they are going to perform.

• 1700 Command

• 1800 Diagnostics

• 1900 Status

• 2100 Average TIC Data (4393A Card)

• 2101 Raw TIC Data (4393A Card)

3.4.2.1 Command Port (1700)

System commands can be issued to the ATS-6511 via the command port. These commands provide a limited set of operations to be used for remote control of the system. Typically, a remote monitoring station may record an error that indicates user intervention is required. The remote monitoring station would then be able to access the command port via the Ethernet and issue the commands required for recovering from the error. The following list provides a short description of each command.

Note: All commands are in lowercase and the commands are case sensitive.

3.4.3.2 Diagnostic Port (1800)

The ATS-6511 provides an IP port to aid in diagnosing system errors. Each of the subsystems within the ATS-6511 provides diagnostic output that can aid in identifying system errors. It is typically not necessary for users to access the diagnostic port because all system errors are reported on the front panel (Alarm Light), in the alarms list (status alarm) and/or can be recovered using the syslog command.

ATS-6511A/B/C Users Guide

DOC 6511_Release K

Diagnostic messages are only displayed on the diagnostic port. If users wish to save the messages provided by the diagnostic port then the output of this port must be saved to a file. It is recommended that diagnostic messages be saved only to remote systems and not locally on the ATS-6511. Storing files locally may cause the file system to exceed its storage capacity and the ATS-6511 will no longer operate.

The options for the diagnostic outputs include error, info, or debug messages from the, subsystems listed below. To determine the current settings telnet into the command port and use the settings diaglog command.

ATS-6511B>settings diaglog

To change the settings use the diag command then specify which message types (error, info, or debug) you would like to see for the desired subsystem. Example – if you want to look at the debug messages for the kas2 use the diag kas2 debug command. You can verify this by using the settings diaglog command.

Users can modify these settings as needed and are able to save these settings to the default start up if desired by typing save. These settings can also be saved to a different configuration file if desired by typing save and providing a configuration filename.

3.4.3.3 Status Port (1900)

This port provides users with real time system status updates. As the fields that are displayed using the config, settings, status, and network commands are updated internally they are forwarded to this port in real time. Users wanting to display system parameters, measurements,

ATS-6511A/B/C Users Guide

DOC 6511_Release K

and/or alarms in real time are able to use the data provided by the status port to update their displays in real time. See Appendix C for an example of the data provided by the status port.

3.4.3.4 Average TIC Data Port (2100)

This port provides users with average measurement results from each of the 4393A TIC Cards installed in the ATS-6511.

3.5 Status Command

The ATS-6511 provides overall system status, health, and measurement results via the status command available on the command port (1700). For more detailed information and a description of the fields refer to Appendix B.

Status provides a sequence of field names to distinguish various devices and information from one another. Each information field has a unique ID. Users can display the entire set of data fields using the status command. It is possible to further refine the data requested by adding additional information fields to the command line. For example, if the user simply wanted to get the information on this system type status unit.

Users can further refine the requested data fields by adding the desired information line to the field to look for specific data. If the user wanted to look for the system uptime, the user would simply add a “:” then the sub-category under unit. Additional subcategories can be added to the command line, separated with the “:”.

4 Theory of Operations

The ATS-6511’s function is the generation of timing signals extracted from the proprietary time code contained in the fiber cable connected to an upstream 4372A installed in an ATS-6501.

4.1 Generation of Timing Signals

An OCXO serves as the low noise disciplined reference for the ATS-6511. The frequency of the low noise OCXO is measured against the frequency from the fiber signal and the low noise OCXO is steered to be on frequency. The phase adjustments made to the OCXO allow it to be aligned with UTC(USNO), via the ATS-6501 which is the source of GPS time and is used as a long term frequency reference. In doing this, the ATS-6511 exhibits the short-term frequency stability characteristics of the OCXO while exhibiting the long-term characteristics of GPS. The OCXO provides low phase noise performance for the 10 MHz outputs.

The 10MHz output provided by the OCXO serves as the time base for the ATS-6511. All timing signals (e.g., 1 PPS, IRIG-B, 10 MHz) are derived from this reference and thus exhibit the same frequency and phase characteristics. The 100 MHz TCXO which is the clock for the main FPGA is divided by 10 and phase locked to the OCXO 10 MHz output. The rear panel 10 MHz plug in card has a D/A converter which is used along with a sine look up table to provide a 10 MHz signal from the 100 MHz internal clock. This D/A output is then filtered and distributed to the four outputs of the plug in card. The FPGA which is clocked by the 100 MHz TCXO provides 1 PPS and serial time codes which are used by the 1 PPS/DC IRIG and AM IRIG cards to produce 1 PPS and IRIG time codes.

The 2 channel Low Noise Synthesizer (LNS) contains the low noise OCXO. A 1 PPS signal is generated in the LNS which is used to measure the fiber optic 1 PPS time of arrival. This measurement is used by the software PLL to steer the OCXO frequency to keep the ATS-6511 1 PPS on time with the ATS-6501. Commands are sent by the CPU to the Low Noise Synthesizer clock to adjust the analog control voltage to the OCXO as a means of affecting this steering.

The PPS signal from the fiber is used in aligning both the IRIG-B signal and the CPU clock to UTC(USNO). At startup this PPS is used to align the internally generated 1 PPS and IRIG-B signal with the correct 10MHz clock cycle. From that point on the 1 PPS and IRIG-B signals are kept on time by using the OCXO 10MHz signal as its reference. The 1 PPS signal from the fiber generates an interrupt to the ARM 9 processor which serves as an indicator of the top-of-second. This is used by the CPU along with EPOC messages received from the fiber to set the CPU time to UTC(USNO).

When both fibers inputs are no longer available the ATS 6511B and C provides superior holdover performance frequency locking the OCXO to the internal Rubidium or external reference input.

4.2 Startup Sequence

A very specific sequence exists for starting each of the internal devices within the ATS-6511. This sequence exists to ensure that the unit generates the appropriate timing outputs and that they are all in sync with each other. Startup time of the ATS-6511 varies from 5 to 15 minutes depending upon how long the unit has been powered off but the timing outputs are not enabled until 1 PPS and 10 MHz are accurate.

ATS-6511A/B/C Users Guide

DOC 6511_Release K

The fiber inputs A and B are monitored for signal presence and their time code, frequency and 1 PPS are extracted. If both signals are present, the unit will begin steering the OCXO to fiber input A’s frequency. Once the OCXO frequency is within 1e-10 of the fiber input frequency, the software propagates the fiber 1 PPS signal through the unit and the front panel indicator “OSC LOCK” will illuminate green. The software then begins using the system 1 PPS vs. fiber 1 PPS measurements to steer the phase of the system. The 10MHz frequency reference measurements are made on the internal OCXO source. The internal OCXO is generally warm and operational within 10 minutes. Once the phase has been steered to within 10 ns of the fiber 1 PPS, the outputs are enabled. The software will continue to steer the OCXO phase to keep the phase within 100 ps of the ATS-6501 1 PPS.

The Time Code generator uses 10 MHz, 1 PPS, and system time to generate the IRIG/NASA36 signals. As a result, it is the final step in the startup procedure. The Time Code generator uses the 10MHz as its frequency reference and the PPS to indicate the start of the second. These two signals serve as the time base for the Time Codes. System time is sent by the CPU to the Time Code generator to indicate what time is associated with the received PPS signal. This information is then used to produce the user/factory defined time codes.

5 Maintenance

The recommended maintenance schedule for the ATS-6511 is outlined in Table 5-1. Although this schedule is sufficient for most applications, it may be necessary to increase the number of scheduled maintenance events for extremely dusty or dirty environments. Contact Symmetricom if there are questions about the scheduled maintenance cycle.

A minimal amount of maintenance is required for the ATS-6511. It is designed to operate continuously over long periods of time with little to no interaction. The primary factor in maintaining a working unit is to verify that it remains dust free and the fiber connectors and cables are in good condition. The following maintenance schedule is applicable.

Monthly None Semi-Annual None Annual 1. Fan Filter1

2. Fiber Cable Inspection

3. Internal Inspection2

Table 5-1. Maintenance Schedule

Maintenance Required

5.1 Internal Inspection

The internal inspection of the ATS-6511 is necessary to ensure that all components are relatively free of dust and particles that may cause electronic components to fail. The following instructions outline the required steps in performing an internal inspection of the ATS-6511.

1. Shut the system down.

2. Remove the top of the ATS-6511.

3. Visually inspect the various components and make sure that an excessive amount of

dust is not present. Excessive dust can be removed by using compressed air or vacuum cleaner to clean the electrical components of any accumulated dust.

4. Use a vacuum cleaner to clean the fan filter of any accumulated dust.

5. Re-install the cover on the ATS-6511.

6. Restart the system.

5.2 Fiber Cable Inspection

The fiber cables are a common source of system locking failure because they are fragile and can be inadvertently damaged by pinching or bending too tightly. The following process outlines the steps required in performing an inspection of the fiber cables.

1. Follow the fiber cable from the rear of the ATS-6511 as far as possible away from the

unit. Look for any severe bends in the cable or damage to the shielding of the cable.

2. Remove any severe bends in the cable and replace any damaged cables.

In extreme operating environments it may be necessary to clean the fan filter more frequently.

Internal inspections are only required if the fan filter is extremely dirty.

ATS-6511A/B/C Users Guide

DOC 6511_Release K

3. Inspect the connectors. Verify that the cable connectors are not damaged at the

connection to the ATS-6511, upstream 4372A/4372A-T (ATS-6501) or TSC-4340 (1U 1x8 Fiber Distribution Amplifier.

5.3 Fan Filter

The fan filters helps protect the system from accumulating dust inside the unit as well and allows the fans to provide the proper level of cooling for the internal components. It is important to keep this filter clean to allow the proper level of air flow to prevent the system from overheating. To clean the filter:

1. Remove the fan assembly from the front by loosening the two captive screws.

2. Remove the filter from the fan assembly.

3. Use a vacuum cleaner to clean the fan filter of any accumulated dust.

4. Re-install the filter and assembly into the chassis. Take care to feed the cable into the

chassis while inserting the fan assembly.

6. Troubleshooting

The following section provides some basic troubleshooting information to assist users in case they suspect there is an issue with the system.

6.1 Front Panel Indications

You can use the front panel indicators to assess the status and operation of the unit. Under normal operating conditions the user should see:

• Green Status Indicator on both power supplies

• The front panel clock should display the last two digits of the year, the correct Julian

Date (see appendix D.) and the correct time (UTC). The time should also increment

each second.

• The Alarm Light is Off

• The OSC Lock, Input A or Input B (for redundant systems), and Outputs Enabled

lights are green. Redundant fiber input flashing green (auto) or red (manual).

6.2 Alarm Light

The alarm light will turn red when the unit has detected a hardware failure or an event has occurred that may cause the timing signals output by the unit to be outside of their specifications.

• Either power supply missing/failed or without AC/DC input power.

• Any output module reporting a failure or is not locked to the reference

• There is an internal hardware error

• Reference clock wander has exceeded 100 ns from the input fiber frequency

• Master reference signal is missing.

• Over temperature (65 C)

• I2C Bus error

• System settings do not match the specified configuration in the system mode

If the alarm light is on users can determine the exact cause of the alarm by accessing the command port and typing the status alarm command and obtain a list of the current alarms.

If the alarm light was on and is currently off, users can connect to the command port and type the command syslog to obtain the list of errors from the error log file maintained by the system.

6.2.1 Power Supplies

The system has two power supplies and is capable of operating from either supply in the event one of them fails. If one of the status indicators on the power supply front panel is red there is a problem with that supply. The front panel alarm light should also be on. Power supply #1 is on the left and Power Supply #2 is on the right. The possible problems are listed below:

• Power Supply has failed

• Internal Fuse is open

• Power Supply is unplugged, make sure the power supply is plugged in

DOC 6511_Release K

ATS-6511A/B/C Users Guide

• Power Source has failed; ensure the power source is available and connected to

the rear panel of the unit.

Users can also check the current system using the status alarm and the status health:power_supply commands to check the system status.

6.2.2 Fiber Inputs

The system has two fiber inputs (A and B) and one of these will always be the master (primary) input. The master input will always display a solid green indication on the front panel when the reference signal from the ATS-6501 is being used to steer the internal clock and a solid red when the signal is lost. The redundant input will flash green/red (on 1 second/off 3 seconds) when the reference signal from the ATS-6501 is present. The redundant input will also be red when the reference signal is lost.

Input A/B Indicator Description

Steady Green Fiber input has been selected as the master and reference signal is present Flashing Green Redundant fiber input is available and the system mode is auto. Steady Red Reference signal is not present or fiber setting is incorrect. Flashing Red Redundant fiber input is available and the system mode is manual.

6.2.9 Configuration Not Readable

The internal bus used to communicate with the plug in modules and power supplies to determine their type and serial number is the I2C bus. If this alarm occurs the system should continue to operate correctly, but the unit should be power cycled at a convenient time to resolve this extremely rare condition. It the alarm is still active after a power cycle, return the unit for repair.

6.3 Communication Problems

This section describes some of the errors associated with communications problems and some potential sources of those issues.

6.3.1 LAN

• LAN Connector unplugged.

• DHCP

o When the system is operating press the “Display” button on the front panel. If

the IP Address is set it should switch to those displays and give the local operator the IP Address. If not, the IP Address was not set it will not display the IP Address and the unit will assign an IP Address of 0.0.0.0. Plug the LAN Connector into the rear of the unit and if a DHCP server is available, the unit should obtain an IP Address.

o Power cycle the unit.

• Static o Verify the static IP address Netmask, Broadcast IP, and Gateway were set

properly using the network command.

o If incorrect, Use the network_config command to set the correct Mode, IP

address, netmask, broadcast, and gateway.

6.3.2 Console (Command Port)

• USB to Serial adapter the improper type (ATS 94000-115200)

• Improper baud rate set on terminal serial port

o 115200,N,8,1, no flow control.

• Incorrect serial cable type (requires Null Modem cable.)

6.3.3 External Reference Adapter

• USB to Serial adapter the improper type (ATS 94001-5071A)

• Improper baud rate set on external reference serial port

o 9600,N,8,1, no flow control.

• Incorrect serial cable type (requires Null Modem cable.)

• Communication settings on the reference device are incorrect.

o Refer to the manual and set the system to 9600,N,8,1.

Note: Communications are only used when the external frequency reference is a hp5071A. If you are using a different cesium clock use the reference_type cesium command to set the proper reference clock type. This also applies when using the 5071A and the ATS-6511B or C will not be communicating with the clock.

6.4 Syslog Command

All system error messages can be listed using the syslog error command on the command port. The following information is typically contained in this log during startup. The date/time will be set to Jan 1 00:00:00 when the system is first powered on or rebooted since the time is not set until the unit is tracking the fiber input.

Appendix C Status Port (1900) Example

The data in this first section (boot+) is provided each time the user connects to the status port. It allows users to obtain all of the system settings/config/status/network parameters each time they connect to the status port. Once this data is sent the only data forwarded from this port is the data that has changed since the system has been running. This data will be preceded by the date and time of the event as this information is updated. It is important to recognize these parameters are also reflected in the results from the status command.

Appendix D. Detailed Command Information

The commands are listed alphabetically. Each command is listed with an explanation of what it does along with examples. All of the commands are case sensitive. The system will inform the operator that the commands were executed by returning an “OK” or other language denoting the command has been accepted. Operators will be informed if the system cannot recognize the command or syntax that was entered. In such cases where the data value entered is out of range or is incorrect the ATS-6511 will generate an error message and will leave the current operating value for that parameter unchanged and provide the operator with the acceptable range of values.

The system will recognize alphanumeric characters as well as the dash (-), single quotes ’’, and the underscore ’_’ when attempting to save user configuration files. Use of any other characters is prohibited and strictly enforced and the user will be informed they attempted to use an illegal filename.

If the system cannot recognize the configuration, status, network or settings parameter the operator is requesting it may return “no info”. Make sure the fields were typed correctly for the data you are attempting to retrieve.

Command Arguments:

• [ ] Any arguments contained are optional and can be left out if desired.

• < > Any arguments used with command.

• | is used to separate alternative inputs for a single parameter (e.g., On/Off, 1/0)

Alarm:

Description:Displays the current alarm state of the instrument. Equivalent to issuing the status

alarm command. The returned alarm information provides the most significant alarm condition that is currently active. It does not necessarily indicate all alarm conditions which are currently present. For that purpose, health nodes are used to monitor the current state of the instrument and raise alarms when the specified condition is detected. The health nodes themselves are part of the status tree and can be viewed by typing status health at the command prompt.

Once a health node alarm is triggered it will produce one of two types of alarms:

• Event alarm: Used to indicate alarms that have occurred but do not have a

persistent state. These alarms are latched and will remain active until the user clears them with the clear_alarms command. Such an alarm might be triggered by the loss of an external reference because even though the unit may switch to its internal reference and continue to operate, the event is significant and warrants the attention of the user.

• State alarm: Used to indicate alarms that represent the current state of the

temperatures within the instrument. The alarm itself will not clear until the operating temperature returns to normal conditions..

Syntax: alarm <-d MAX_DEPTH> <NODE>

MAX_DEPTH limit display to MAX_DEPTH levels of data

NODE specifies a node to display
