Functional Overview

Functional Overview

The TimeProvider 500s function is to communicate with a PTP grandmaster clock,receive timing information through a PTP flow, and make corrections to a localclock. The local clock is then converted to a T1 or E1 signal, PPS signal, or

sinusoidal 10MHz signal for use in a variety of applications. The TimeProvider 500serves as a translator between timing over packet and traditional SONET/SDHnetworks. Set up and monitoring is managed over a serial port or a remote telnetsession using the TimeProvider 500s CLI command set.

Chapter 1 Overview


RJ48C Connectors

The stack of 2 RJ48C connections labeled OUT3and OUT4 can provide twoseparately driven output signals, configurable as either E1 or T1. These aredifferential outputs (tip and ring) conforming to signal levels defined in G.703.

1PPS/E1/T1 Output Connectors

The TimeProvider 500 provides configurable outputs at either 1PPS, E1(2.048MHz), or T1 (1.544MHz) frequencies. See Configure Frequency Outputsformore information. Specific signal types at each frequency are detailed in the CLIcommand, set output out1, out2, out3 & out4, on page 103.

There are E1/T1 channels provided at a BNC connector (OUT1and OUT2) and an8-pin modular connector (OUT3and OUT4). However, there is a separate driver foreach of the 4 outputs (2 BNC and 2 RJ48C) so that all of the connectors can beloaded simultaneously as desired. Each of the two channels control the output type.The BNC provides a 75single-ended interface while the RJ48 provides a 100balanced connection. Since there are only two E1/T1 channels, Figure 1-5showswhich outputs are coupled in terms of frame type. Output 1 and Output 4 arecoupled together and Output 2 and Output 3 are coupled together.

Figure 1-5. Output Connector Frametype Coupling

The output can be observed on an oscilloscope by connecting directly from the

OUT1or OUT2BNC connectors or the OUT3or OUT4RJ48C connectors.

The signal connections on the RJ48C connectors provide differential outputs onpins 4 (ring) and 5 (tip), per ANSI T1.403. To properly observe the outputs via theRJ48C connection on a scope requires the use of a balun to convert to asingle-ended signal. There are many types of measurement devices that aredesigned for use with differential signals, which would be appropriate to use directlywith the RJ48C outputs (for example, a device that can evaluate the framing).

Note: The RJ48C physical connector is the same size as RJ45 (an

8-pin modular connector). RJ45 is used for Ethernet whereas the term

RJ48C is used for E1/ T1 lines. The pinouts for RJ45 and RJ48C are

different. RJ45 (Ethernet) uses pins 1, 2, 3 and 6 whereas RJ48C uses

pins 4 and 5.

OUT 4

OUT 3

OUT 1 OUT 2

The frame format and disable controls are coupled between outputs 1 and 4 andbetween outputs 2 and 3. For non-1PPS signals, these output pairs must have thesame signal type since they share the same framer. Only outputs 1 and 2 can beconfigured for the 1PPS signal.

If output 4 is disabled, then output 1 will be disabled if it is not configured for 1PPS.

Outputs 3 and 2 have a similar coupling.

For example, if output 1 is configured for 1PPS, then output 4 can be configured forany signal type, except 1PPS. If output 1 is configured for E1, then output 4 must beconfigured as an E1 with the same frame format.

This section will only use if0 (interface 0) which applies to networks not using VLAN.A discussion of if1 through if4 (interfaces 1 through 4) used for VLAN can be found

in Interface Connections, on page 55.

Using the TimeProvider 500 IP address information in Table 2-2, and the setipcommand, the following example shows how to set the TimeProvider 500 IPaddress to Table 2-2. Although the subnet mask is not changed from the factorydefault settings, it can be changed with the set ipCLI command.

Example:

TP-500> set ip if0 192.168.1.5 netmask 255.255.255.0 gateway 192.168.6.1

After setting the IP address for the TimeProvider 500, type show interface configtoverify that the IP address of the TimeProvider 500 is reconfigured per the entries

made with the setipcommand as shown in Figure 2-5.

Confirm TimeProvider 500 Network Communication

If not already done, a standard RJ45 Ethernet cable should be connected from theTimeProvider 500 port labeled 1588 into the network that will provide connectionto the grandmaster clock(s). See Figure 1-4. TimeProvider 500 connection is

100Base-T.

There are a number of ways to confirm that the TimeProvider 500 is now available

on the network. The following is a method available on any WindowsPC:

1. From a PC that is on the same network as the TimeProvider 500, select Start >Run.

2. In the Run dialog box, selectcmd, then click OK. This initiates a commandsession as shown in Figure 2-6.

3. At the prompt, type pingfollowed by the TimeProvider 500 IP address, then

press Enter. See Figure 2-6. The example shows successful connection.

44/174



If ping was not successful, here are some considerations:

First, ensure that a physical link has been established from the TimeProvider 500to whatever it is connected to (likely a switch). The small green LED in theupper-right-hand corner of the 1588 connector on the TimeProvider 500 (seeFigure 1-4) should be lit solid green. If it is not, there is likely a basic link problem.

A similar check can be done on the computer being used for the ping. For theremainder of this discussion, it is assumed that the user is able to establishconnection from the computer into the network that includes the PTP flow of theTimeProvider 500 being used.

Once the physical link is established, ensure that the device linked to theTimeProvider 500 is capable of running 100Base-T. The TimeProvider 500 willauto-negotiate the rate, but does not support speeds other than 100Base-T.

Configure PTP Settings

Now that the TimeProvider 500 is configured for the network, configuration of PTPsettings can be configured for access to the target grandmaster to establish PTPpacket flow. Using the show ptpcommand, current PTP configuration data is shownin Figure 2-7.

Figure 2-7. GrandMaster (GM1) Factory Default Settings

Setting the Target Grandmaster IP Address

As with the TimeProvider 500, the IP address for the grandmaster will likely becustomized for your system network. The IP address of the grandmaster isconfigured on the grandmaster. To configure the TimeProvider 500 to use thegrandmaster IP address, use the set ptp addresscommand as shown in thefollowing example:

Note:Auto-negotiate can be disabled using the set auto-negcommand.

Configuration Setup

TP-500> set ptp address gm1 192.168.1.100

TimeProvider 500 will respond with:

Grand Master 1 address set to 192.168.1.100

Confirm that the setting for the target grandmaster address is now configured byusing the show ptpcommand.

Figure 2-8. Confirming GrandMaster (GM1) IP Address Setting

Configure GrandMaster (GM2) Clock (Optional)

The TimeProvider 500 allows you to select two grandmaster clocks for its source ofsynchronization. Configuring the target address for the second GrandMaster (GM2)

is similar to the configuration for the primary GrandMaster (GM1), except that GM2is used in the set ptp addresscommand instead of GM1. Confirmation of the secondGrandMaster (GM2) address can be seen via show ptpas shown in Figure 2-7. Inthe example, note that the GM2 IP address is shown as 0.0.0.0, which is the factorydefault (unconfigured). If the second grandmaster is not used, it is recommendedthat the 0.0.0.0 setting be left unchanged so that the TimeProvider 500 does notattempt communication with a second grandmaster.

Confirm Connectivity with Grandmaster Clocks

To confirm connectivity with GrandMasters (GM1/GM2), follow these steps:

1. Use the show ptpcommand to view the current PTP settings. See the GrandMaster IP address shown in the Setting the Target Grandmaster IP Addressexample.

2. Use the pingCLI command to confirm connectivity between the TimeProvider500 and the targeted grandmaster clock.

TP-500> show ptp

If there is connectivity, TimeProvider 500 will produce a response similar to thefollowing:

TP-500> ping if0 192.168.1.100

Pinging 192.168.1.11 [192.168.1.100]:

Reply from 192.168.1.100: time=0ms

If there is lack of connectivity, TimeProvider 500 will produce a responsesimilar to the following response:

TP-500> ping if0 192.168.1.100

Pinging 192.168.1.11 [192.168.1.100]:

Request timed out

If the ping request times out, here are some considerations to help troubleshoot:

All of the items listed for troubleshooting connectivity with the TimeProvider 500in Confirm TimeProvider 500 Network Communication, on page 43should beconsidered.

The targeted grandmaster clock settings should be reviewed, if available. Forexample, check the address settings it is actually using and anything related tonetwork configuration. For example, there could be firewalls in place preventingconnection.

If VLAN is being used in the TimeProvider 500, it is essential that thegrandmaster also be a member of the same VLAN (established by thevlan_configCLI command). If VLAN is enabled, and two grandmasters aretargeted by the TimeProvider 500, then both must be in the same VLAN with the

same VLAN-ID. See Configure PTP Settingsfor more information.

Confirm PTP Flow

When connectivity between theTimeProvider 500 and the grandmaster clock(s) isestablished, the actual PTP flow begins. The TimeProvider 500 starts PTP flow witha request to the grandmaster clock(s) to send it the appropriate set of PTP packetsat the desired rate and for a desired duration. Once flow is established, theTimeProvider 500 periodically sends a new flow to prevent a time out. Theautomatic time out allows client clocks (such as a TimeProvider 500) to be removedfrom the network without continuously consuming resources from the grandmaster

clock.

For a quick visual check for PTP flow, view the LED in the upper right-hand cornerof the RJ-45 connector labeled 1588 (see Link and Flow LED in Figure 1-4). Ifthere is flow, the Link and Flow LED will blink at a high-rate (multiple blinks persecond). Next, type show statusto view a list of current PTP-related settings, asshown in Figure 2-9.

Configuration Setup

Figure 2-9. List of Current PTP-Related Settings

Possible Flow State, on page 65shows several events related to PTP flow that canbe used to check on successful flow.

If the PTP flow is not as expected, here are some considerations:

Although it would likely require special user configuration, make sure thegrandmaster clock does not have its PTP port disabled. A disabled port will notsupport PTP flow. TimeProvider 500 provides a similar setting (see the set ptpaddr-modecommand), but the port is enabled by default.

Although perhaps unlikely, it is possible that the grandmaster does not havesufficient resources to support the requested PTP flow. For example, agrandmaster has a limit on how many clients can be supported.

A quick check for PTP flow can be seen by looking at the 1588 connector's LEDs.However, for a more reliable and detailed confirmation of PTP flow, use the showstatusquery to observe the actual flow rate shown in the Flow Direction section ofthe status response from the TimeProvider 500 as shown in Figure 2-9. See Detailsfor Show Status Function, on page 63for more information about the results of theshow statusquery.

Configure Frequency OutputsBy factory default, the TimeProvider 500 produces 2.048 MHz output and 1PPSoutput. If this is the desired output, no configuration is needed.

The show outputcommand identifies the current output configuration. Thefollowing example shows that the TimeProvider 500 is currently generating 2.048MHz clock from OUT1, OUT3, and OUT4 and a 1 PPS signal from OUT2.

Configuration Setup

Optional Configure VLAN Settings Example

When one of the external network devices or telnet sessions communicating withthe TimeProvider 500 is using VLAN, interface connections are available to supportthe external network devices (GM1, GM2, node manager) or remote telnetsessions. For interface connection information, see Interface Connections, on page55.

An interface connection for communication between the targeted external networkdevice or remote telnet session and the TimeProvider 500 needs to be establishedbefore a VLAN connection can be established. In this example, the procedure to setup a VLAN connection for a GM1 is described.

To connect the TimeProvider 500 with a GM1 using VLAN, perform the followingsteps:

1. Disable any current PTP flow.

At the TP-500>prompt, type setptp addr-mode disable, and then pressEnter

2. Enable a VLAN interface to use. For this example, use inte
