The IEEE 1588 card can be configured to operate as a PTP grandmaster or as a PTP slave. 2 As a PTP grandmaster, the IEEE 1588 card typically synchronizes PTP slaves on the network to International Atomic Time (TAI). The XLi IEEE 1588 Clock derives TAI from the Global Positioning System (GPS). In addition, Symmetricom designed the XLi IEEE 1588 Clock so the user can distribute Coordinated Universal Time (UTC) or user-entered time over PTP. 1 As a PTP slave, the IEEE card automatically discovers a PTP master within its subnet/subdomain and synchronizes to it. The PTP slave in turn, can be configured as the primary reference source for the XLi IEEE 1588 Clock (the clock synchronizes to the PTP slave). The XLi’s Time Interval/Event Time (TIET) feature can be used to measure PTP synchronization across timing networks. For example, to measure a PTP slave’s synchronization to the PTP grandmaster, the user connects the PPS output of a PTP slave to the XLi IEEE 1588 Clock and configures F110 to display the time interval between each PPS. See F130 - Precision Time Protocol Status (page 116) and F131 - Precision Time Protocol Network Config (page 119) for more information. Standard Configuration 5 The XLi IEEE 1588 Clock can be purchased in two configurations. The first configuration includes one IEEE 1588 card preconfigured as a PTP master and located in Option Bay 4. The second configuration has an additional IEEE 1588 card preconfigured as a PTP slave located in Option Bay 2.

See “F131 - Precision Time Protocol Network Config” on page 119. GPS C/A Receiver (87-8028-2) Introduction The GPS C/A Receiver acts as a Stratum 0 timing reference source to the XLi. It tracks up to 12 L1 GPS satellites, decodes their signals for time and position, and feeds this data to the XLi through the internal backplane. When available and enabled, the GPS C/A Receiver card provides superior time and frequency accuracy on the XLi (See “System Time & Frequency Accuracy” on page 10). The GPS C/A Receiver card comes with an L1 GPS antenna, cabling, and mounting hardware unless otherwise specified at the time of purchase. The GPS C/A Receiver uses a TRAIM (Time Receiver Autonomous Integrity Monitoring) algorithm to monitor the integrity of the receiver’s timing solution. Using redundant measurements, TRAIM detects and quarantines anomalous GPS signals, independent of the GPS health ephemeris data. The quarantined signal is excluded from the timing solution for 12 hours before it is requalified for inclusion in the timing solution. See “Installing the GPS Antenna” on page 15 for information on selecting an antenna site, mounting the antenna, and signal strength requirements. The GPS C/A Receiver card can be managed and configured using F53 – GPS Operation Mode (page 58) and F119 – GPS Receiver Configuration (page 110). 4 XLi IEEE 1588 Clock 997-01510-03, Rev.

If a timing reference is not available (or becomes unavailable) and Aux Ref is enabled, the XLi locks to the Aux Ref input. Under those conditions, frequency output accuracy is equal to the reference < 1 x 10-12. Note: To set the time and date manually, see “F3 – Time & Date” on page 40.

To accomplish this, the user sets up the GPS antenna, connects it to the GPS receiver in the XLi IEEE 1588 Clock, and configures GPS as its primary reference source. When the XLi IEEE 1588 Clock locks to the GPS reference source, it computes TAI and synchronizes the PTP grandmaster (the IEEE 1588 card). When the PTP grandmaster is synchronized to the XLi IEEE 1588 clock it starts operating, sending out PTP Sync and Follow_Up messages and responding to PTP requests. 1 Selecting a GPS Antenna Site Select a site outdoors that... • • • • • • • Is the highest point available Offers a full 360° view horizontally, to within 10° vertically of the horizon Is higher than neighboring buildings/obstructions Is protected from strong radio frequency (RF) and microwave transmissions Is set away from RF-reflective surfaces that cause multipath interference Is set 3 ft.

C, 12/12/2006 15 S 1 S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S Blocked signals and multipath cancellation significantly increase GPS acquisition time. Multipath cancellation is caused by reflected signals that reach the antenna out of phase with the direct signal. Multipath cancellation and blocked signals are typically caused by vertical reflective objects positioned to the side and above the antenna. To solve these problems, mast mount the antenna at least 1 meter away from and above the reflecting surface. Verifying the Site Verify that the length of cable from the GPS antenna site to the XLi does not exceed the maximum GPS antenna lengths recommended to meet the GPS signal strength requirements. When calculating the total antenna cable length, include cable that is needed to meet safety and regulatory requirements, such as lightning arrestors and building code requirements for running coaxial cable from the exterior to the interior of a building. If possible, test the GPS signal reception of a particular site before mounting the antenna and running the cable indoors. Some sites may turn out to be unsuitable due to interference. Notes: • • • • • The XLi requires a 12-volt compatible antenna. Antennas not rated for 12 V will be damaged. Use a splitter, not a BNC “T” connector, when connecting an antenna to multiple receivers. The L1 GPS antenna is designed to operate with up to 150 ft. (45.72 m) of RG-59 coax cable. A line amplifier is available for cable runs between 150 - 300 ft. (46 - 91 m) in length (RG-59). A down-converter kit is available for cable runs of 1,500 ft. (457.2 m) in length (RG-58). Mounting the GPS Antenna Mount the GPS antenna on an antenna mast (recommended) or on the peak of a building. For the mast, use 2-inch (5.08-cm) diameter PVC pipe or conduit that is rigid enough to withstand high winds without flexing. Use guy wires to stabilize masts longer than 10 ft. (3.048 m). Avoid mounting the antenna on a tower, which requires a specialist to maintain. 16 XLi IEEE 1588 Clock 997-01510-03, Rev.

Symmetricom recommends using the standard 12-volt capable antenna and cable provided with the GPS receiver. 1 Figure 4: GPS Signal Strength Requirements Connect the GPS antenna cable to the GPS receiver’s ANTENNA connector at the rear of the XLi. Note: Use a 12-volt capable GPS antenna. Making Additional Connections and Powering Up Make the following connections to the XLi (all cables supplied): 1. For access to the web and command line interfaces, connect NET network port (on the Main CPU Card, 87-8000) to the LAN using the Cat 5 network cable (supplied). For local access to the command line interface only, connect the SERIAL I/O port (on the Main CPU Card, 87-8000) to the to the PC’s serial port using a null modem cable. 2. Connect the 1588 network port to the timing network. 3. Connect the AC Power Supply it to a power source. The green STATUS light on the power supply indicates that the XLi is receiving power. Upon receiving power, the XLi goes through its startup sequence; displaying “BOOTING”, “LOADING”, and “STARTING”. After approximately 40 seconds, the XLi displays the clock status, and user interfaces (front panel/command line) become available. The IEEE 1588 card requires an additional 2 minutes to complete its startup sequence before it is available from the user interfaces. Warning: Ensure that a disconnect device, such as a switch, with the appropriate voltage/ current rating is provided when operating/installing the XLi. 18 XLi IEEE 1588 Clock 997-01510-03, Rev.

Do this if you plan on using the command line or web interface to manage the XLi over the network. Using the front panel keypad/display configure the network port settings as follows: Press Result ENTER Displays “FUNCTION” 100 Enters 100 as the function number ENTER Displays Function 100’s first screen: “COMPANY 00-A0-69…” ENTER Displays “IP ADDRESS…” 1-9… Enter the unit’s IP Address (e.g., 192.168.0.11 ENTER Displays “SUBNET MASK…” 1-9… Enter the Subnet Mask (e.g., 255.255.255.000) ENTER Displays “DEFAULT GATEWAY…” 1-9… Enter the Default Gateway’s IP address (e.g., 192.168.0.1) ENTER Displays “10-100 BASE-T (CURR BW 10) - AUTO” ENTER Displays “REMOTE LOCKOUT – UNLOCK” (Leave unchanged) ENTER (5 times) Displays “SAVE CHANGES – YES” ENTER Saves the new network parameters, and reboots the XLi 2 1 Configuring the XLi 5 Enter the XLi’s IP address as the address in a browser and log on to the XLi’s web interface. The factory set user name is “operator1” and the password is “zeus”. If this XLi was field-upgraded for IEEE 1588 operation, the password may also be “casey”. • • • Click the Admin Home link and then the Accounts Admin link. Change the factory set user names and passwords. Click the Admin Home link and then the Option Bay # GPS M12 RECEIVER link. - Verify that the Antenna Cable Delay is correct. For the standard 50 foot (15.24 m) coaxial cable supplied with the GPS antenna, the Antenna Cable Delay is 60 ns. To compute the correct value for other antenna cable lengths, see “F51 – GPS Antenna Cable Delay” on page 55. - Leave GPS Operation Mode as “Dynamic” and Time Reference as “Primary”. Click the GPS Config & Status link. After approximately 20 minutes of operation, check that GPS Clock Status is locked and GPS Antenna is OK. - If GPS Antenna is OK and GPS Clock Status is unlocked, click the GPS Satellite List link. The Tracked Satellite List should list four or more “current” GPS satellites. It may take significantly longer than 20 minutes for four or more “current” GPS satellites to appear if the GPS XLi IEEE 1588 Clock 997-01510-03, Rev.

If this delay is unexpected, consider relocating the GPS antenna to a better site or troubleshooting the GPS antenna cable. Press the STATUS key on the front panel. The display should show “LOCKED GPS PRI” without an asterisk (“*”). If an asterisk appears, it means that the GPS receiver is currently unlocked from the GPS satellites, this may indicate a problem with GPS satellite visibility or signal strength. Configuring the IEEE 1588 Card(s) Two versions of the XLi IEEE 1588 clock are currently available: The first version has: • • An IEEE 1588 card configured as a PTP master in Option Bay 4 A GPS receiver in Option Bay 1 The second version has: • • • An IEEE 1588 card configured as a PTP master in Option Bay 4 An IEEE 1588 card configured as a PTP slave in Option Bay 2 A GPS receiver in Option Bay 1 Note: With two IEEE cards, be mindful of the Option Bay number when changing the settings. PTP Master Note: The IEEE 1588 card requires 5 minutes from power up to initialize. Until then, the card does not appear in the user interfaces, or is reported as "NOT AVAILABLE". Function F131 is available for configuring IEEE 1588 cards. The IEEE 1588 card located in Option Bay 4 is preconfigured as a PTP master, as shown here: • • • • • • • • • • • • 20 PTP AVAILABILITY - OPTION BAY 4 PTP IP ADDRESS (STATIC) - 010.048.000.103 PTP SUBNET MASK (STATIC) - 255.255.000.000 PTP DEFAULT GATEWAY (STATIC) - 010.024.000.001 PTP DHCP - ENABLE PTP SYNC INTERVAL - 2 SECONDS PTP BURST MODE - DISABLE PTP PORT STATE - ENABLE PTP SUBDOMAIN NAME - _DFLT PTP RESET TO FACTORY DFLT? - NO PTP INIT TO USER SETTINGS? - NO PTP CLOCK CONFIG, BAY 1 - MASTER XLi IEEE 1588 Clock 997-01510-03, Rev.

Using the familiar keypad display interface, modify the following F131 settings: • • • If a DHCP server is not available on the timing network, disable DHCP and set static values for the PTP IP ADDRES, SUBNET MASK, and DEFAULT GATEWAY.1 Configure the following settings on so that the PTP master and PTP slaves match each other: - PTP SYNC INTERVAL - The rate at which synchronization packets are sent out. The factory setting, 2 seconds, is the recommended value. - PTP BURST MODE - Enables quick and accurate synchronization. Generates additional network traffic. - PTP SUBDOMAIN - Defines the PTP master as a member of a logical timing network. (Recommended) Enable PTP PREFERRED MASTER to have PTP slaves on the timing network favor the PTP grandmaster over other potential masters. 2 1 IMPORTANT: If one of the PTP slaves on the timing network is a Symmetricom IEEE 1588 card, the interval for all PTP masters and PTP slaves must be set to 2 SECONDS. PTP Slave To reconfigure the IEEE 1588 card from being a PTP master to being a PTP slave, complete the following steps: 1. Having logged in to the web interface, from the Admin Homepage, click the link Option Bay 4 IEEE 1588 Master. The new 1588 web page takes approximately 5 seconds to load. 2. Set Clock Configuration to Slave Primary. 3. Try operating with Slave Synchronization Threshold at 5 microseconds. Timing networks with bursty or heavy traffic, routers, or many layers of hubs and switches may need the higher 1000 microsecond setting. 4. Click the Submit Changes button. 5. The front panel display should show "LOCKED PTP PRI" soon after. 5 The IEEE 1588 card is now operating as a PTP slave and is also functioning as the primary reference source to the PTP master. The GPS receiver, which was previously operating as the primary reference source to the IEEE 1588 clock, is now a STANDBY reference source. 1. After saving changes, if DHCP is enabled and a DHCP server is available, F131 displays the DHCP-assigned settings following the PTP DHCP ENABLE screen. XLi IEEE 1588 Clock 997-01510-03, Rev.

Distributing non-TAI time over PTP while the PTP slave is a reference source will have a predictable effect on the XLi’s system time. 1 Note: Later on, when reconfiguring the IEEE 1588 card as a PTP master, use F119 to set the GPS receiver as the PRIMARY reference source. (In F119: Set GPS TIME REFERENCE, BAY 1 to PRIMARY.) Note: For XLi IEEE 1588 Clocks with the second IEEE 1588 card in Option Bay 2 (preconfigured a PTP slave, configure the network settings, PTP SYNC INTERVAL, PTP BURST MODE, and PTP SUBDOMAIN. The factory settings are the same as for the PTP master, except the static IP Address is 010.048.000.105 and Clock Configuration is Slave Primary. Rack Mounting the XLi The XLi comes with the following parts needed to mount the XLi securely in any EIA standard 19-inch (48.26-cm) rack: • • 2 mounting brackets 4 flat-head, Phillips screws Have the following items ready and available: • • The appropriate AC source to connect to the XLi’s power supply. A #2 size Phillips bit screwdriver To rack mount the XLi: • • • • 22 Unscrew the four phillips-head screws from the front end of the side panels. Use the same screws to attach the rack mount brackets, as shown. Tighten the screws using a #2 size Phillips screwdriver. Position the XLi in any EIA Standard 19-inch (48.26 cm) rack system, and line up holes in the brackets with the holes in the rack. XLi IEEE 1588 Clock 997-01510-03, Rev.

There is also an Alarm Status LED on the front panel. 2 Alarm Status LED The Alarm Status LED, located on the front panel, displays the alarm-state of the XLi unit. The LED has four states: Dark = Power is off. 1 Green = No F73-related alarms. The current reference source input is locked. Amber = No F73 Alarms. Timeout Delay is counting down, but hasn’t elapsed. The current reference source input is unlocked (e.g. broken antenna cable or no GPS signal) Red = An indicator in F73 has triggered an alarm. Check F73 to find out what the fault/unlock condition is and take appropriate action. Notes: • The amber LED can turn green again while the reference source input remains unlocked because: - F119’s ‘GPS Status’ controls whether the LED turns amber. - F73’s ‘Timeout Delay’ controls how long the LED remains amber. • The blinking of the LED has no meaning. It is a user preference that can be enabled or disabled using the F73’s ‘LED Blink’ setting. If enabled, the LED blinks when it is green and yellow, but stays unblinking when it is red. If disabled, the LED doesn’t blink. 5 Keypad/Display Interface Time Display Press the TIME button on the keypad to display the time only.

Session Timeout and Priority The XLi’s system firmware closes inactive command line sessions on the network port after 15 minutes. The XLi does not terminate inactive command line sessions on the serial port. The user can open a network port session and a serial ports session concurrently, provided the other session is inactive (i.e., not actively performing a function such as F8 - Continuous Time Once-perSecond). The XLi does not allow two or more concurrent network port sessions. A network port session can be active while an inactive serial port session is open. However, if the serial port session receives user input at this point, it takes control away from the network port and does not yield control to the network port again. The network port will show a prompt, but won’t accept additional commands after the serial port has taken control. Attempting to close the network port session and open a new one will fail; a network port connection cannot be re-established until the serial port has been closed. The following transcripts shows a ‘contest’ between a serial and a network port session: Serial port session: >f100 ic f100 IP:192.168.46.150 SM:255.255.255.0 G:192.168.46.1 >NOTICE: A NEW TELNET SESSION HAS BEEN STARTED ON THE INTERNET PORT! >f100 ic NOTICE: THERE IS ALREADY A TELNET SESSION ON THE INTERNET PORT!

System I/O - the status and configuration of the input and output connectors on the rear of the main CPU card (e.g., communication settings, code out, J1, J2, and J3). Subsystem - configuration of the option cards located in the option bays Under Subsystem, the XLi names CPU-aware option cards to the right of the option bay where they are located. Non-CPU aware cards can be present and fully operational in an option bay, but are not shown in the web interface. For more information, see F118 – Option Board Configuration (page 108). Only option bays with CPU-aware option cards will have active links. Clicking the link of an unpopulated or non-existent option bay simply refreshes the web page. 2 When clicking on links, allow each page to load before clicking another link. Clicking links too quickly may cause the Login page to appear. Submitting Changes 1 When submitting changes, only click the Submit Changes button once. Wait for the web page to load before navigating away from the page or submitting another change. Logging Out To log out, click the Logout button located in the upper left corner of the page. If the user closes the browser without logging out, a new session will not be available until the XLi closes the inactive session after 30 minutes. Notes Notes for specific pages in the web interface: • • • Units equipped with the GPS C/A Receiver (87-8028-2): When the user changes the M12 GPS Mode setting and applies the changes, the GPS C/A Receiver goes through several states before attaining the user-specified mode.

Refer to “F: World Map of Time Zones:” on page 193. F1 is the basis for Standard Time and Local Time used by F69. For an expanded explanation of Local, Standard, UTC, TAI, and GPS time, see “F69 – Time Mode” on page 65. For example, to set the time zone for Pacific Standard Time (UTC –8 hours), set the value in F1 to – 08:00. Exclude the 1-hour Daylight Saving Time (DST) offset from this value. DST is handled separately by “F66 – Daylight Saving Time (DST) Mode” on page 63. Because the front panel display and Multicode Output card can be configured to display/distribute Local or Standard time, we recommended configuring F1 as described in the “3: Installation and Set-up” on page 15. The factory setting for F1 is UTC –8:00 hours (Pacific Standard Time). Related topics: • • • “F2 – 12/24 Hour Format” on page 39 “F11 - Time Output Format” on page 50 “F27 – FTM III Configuration” on page 53 Command Line To display the time zone offset, enter “F1 ” on the command line. The XLi responds with the following character string: F1 : where: F = ASCII character F 01 = function number = ASCII space character (one or more)= either no character or + for positive offsets or – for negative offsets = one – or two-digit hours offset from 00 to12 hours : = ASCII character for a colon = two-digit minutes offset = carriage return character = line feed character For example, to set the time zone offset, enter: F1 –8:00 38 XLi IEEE 1588 Clock 997-01510-03, Rev.

The factory settings for F2 are 24-hour format for the display and 24-hour format for IRIG (F90) The user can apply F2 regardless of the time scale selected using F69 (Local, Standard, TAI, GPS, UTC). 5 Typically, 12 hour notation only applied to Standard and Local time. Symmetricom strongly recommends using 24 notation when F69 is set to TAI, GPS, and UTC. Applying 12 hour notation to those time scales is non-standard and causes ambiguous representation of time. For example, if 12 hour notation is applied to TAI, the front panel displays “249:10:21:34” once in the morning, and once at night. Note: Symmetricom strongly recommends using only 24 hour notation for the XLi IEEE 1588 Clock. The 12-hour notation counts hours from 1 to 12 twice per day, like a conventional wall clock. The 24-hour notation counts hours from 0 to 23 once per day. For example, in the 24 hour notation, 18:00 is equivalent to 06:00 in the 12-hour notation (i.e., 18:00 – 12 hours = 06:00). Command Line To display the current hour format, send: F2 XLi IEEE 1588 Clock 997-01510-03, Rev. C, 12/12/2006 39 S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S The XLi responds: F2 DI 1 where: F = ASCII character F. 02 = Function number. = ASCII space character (one or more). D = ASCII character for Display format.= 12 or 24. I = ASCII character for IRIG format = Carriage return character. = Line feed character. For example, to display the current hour format, send: F2 The XLi responds: F2 D24 I24 To set the hour format, send: F2 D12 I24 XLi responds: OK F3 – Time & Date Use function F3 to set the XLi system clock’s time and date. If the XLi is using GPS as its primary reference source, setting F3 manually is unnecessary. Following startup, the XLi synchronizes its time and date to the GPS reference source1. If the XLi doesn’t have GPS as its primary reference source, use F3 to set the time for the IEEE 1588 option card. F3 prompts the user for the Time Mode, the Date in mm/dd/yyyy format, and the Time in hh:mm:ss format. The hours in hh:mm:ss should be given using 24-hour notation (e.g., 6 pm = 18:00). 1. Normally, with the factory configured settings and a good GPS antenna placement. 40 XLi IEEE 1588 Clock 997-01510-03, Rev. C, 12/12/2006 S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S TIME MODE selects which time scale (TAI, Local, Standard, GPS, UTC) is being entered by the user. The XLi, translates the user entry into its equivalents in other time scales. For example, if Local time is 5 hours relative to UTC, entering LOCAL - 07/14/2006 - 10:47:10 in F3 shows up on the front keypad display as UTC 198:15:47:10. TIME MODE in F3 defines only the entry of time in F3; it does not control the time scale displayed or output by the XLi. F3’s Time Mode should not be confused with F69 (see “F69 – Time Mode” on page 65). F69 controls the time scale displayed/output on the front panel display, F8 - Continuous Time Once-per-Second, F9 - Time On Request, and F90 – Code Output Configuration. 2 Notes: • Avoid saving/applying new F3 settings while the XLi is locked to a reference source and distributing time information. Doing so allows the XLi to distribute the potentially incorrect time set by F3 for up to 8 seconds until the XLi re-synchronizes to the (GPS) reference source. If the user applies new F3 settings while the XLi is locked to the reference source, the XLi switches to the F3 time and then back to GPS reference without generating an alarm. With IEEE 1588 packets, for example, this means that the incorrect time would be distributed for a short period of time until the XLi resynchronized with the GPS reference source. 1 Command Line To display the time and date, send: F3 XLi responds: F3 / / : : where: F3 = ASCII string for function F3. = ASCII space character (one or more). 5
