Chapter 1 Overview

Overview

Symmetricom's TimeAnalyzer is an all-in-one test and measurement instrument for

collecting and analyzing IEEE 1588 packet-timing data, as well as analyzing

traditional synchronization signals. This powerful test tool can help you meet the

PTP packet sync performance requirements in every stage of your project:

engineering, network planning, packet-timing deployment and troubleshooting. With

its easy-to-carry portable enclosure, TimeAnalyzer is designed for use in the field,

as well as in the lab.

IEEE 1588 packets may traverse a broad range of networks - such as Ethernet,

Digital Subscriber Line (xDSL), Gigabit Passive Optical Network (GPON), and

Microwave - under a variety of traffic conditions. By measuring Packet Delay

Variation (PDV), users can characterize a network and determine its suitability for

delivering sync packets. TimeAnalyzer can also measure and analyze traditional

synchronization signals, allowing users to validate the synchronization outputs of

independent PTP clients. Both types of measurements are essential to ensure

reliable synchronization.

Using a hardware time-stamp processor that delivers nanosecond caliber-timing

accuracy, and a comprehensive computation engine, TimeAnalyzer collects PTP

data and analyzes in real-time and off-line graphical displays. Measurements

include Packet Delay Variation (PDV), Minimum Time Deviation (MinTDEV), band

TDEV, percentile TDEV, MATIE, MAFE, and Min Time Dispersion. TimeAnalyzer

also features a set of masks in the packet domain that correspond to the masks in

the synchronization domain, as defined by Telecommunication standards. These

masks help determine if the PTP packet flow delivered over the network meets the

synchronization criteria for the application, and allow TimeAnalyzer to present a

very intuitive and user-friendly PASS/FAIL result for the given conditions.

The six masks available for packetTDEV and packetZTIE analysis cover application

requirements ranging from synchronization interface requirements, to traffic

interface requirements, to wireless backhaul frequency offset requirements. Four of

the masks apply to the packetZTIE calculation and two of the masks apply to the

packetTDEV calculation. The masks are described further in Table 1-1 below:

Chapter 1 Overview

Overview

TimeAnalyzer can also perform physical-level frequency and phase measurements

using frequency and timing signals delivered through T1, E1, 10MHz, and 1PPS.

TimeAnalyzer generates various performance data, including MTIE, TDEV,

frequency deviation, and fractional frequency offset, which can be compared

against Telecordia, ANSI, ETSI, or ITU-T requirement masks.

With an easy-to-use GUI for initiating measurements and analysis, TimeAnalyzer's

software enables users to quickly configure a test system and collect PTP

timestamp data for PDV analysis. Users can collect data using a wide range of

sampling rates (1Hz to 64Hz) to allow for pattern and trending analysis. The

timestamp data can also be saved into a file and exported to a network emulator

system for traffic simulation and playback. This export function provides a complete

integration path to test the PTP network using traffic simulation and verification for

R&D development, network planning, and network troubleshooting.

TimeAnalyzer is available in two configurations, the 7500 and the 7100. The

TimeAnalyzer 7500 has all the features of the 7100, and also includes the

TimeWatch Probe module. Figure 1-1 shows the TimeAnalyzer 7500. Figure 1-2

shows the TimeAnalyzer 7100.

Power and Ground Connections

The TP5000 probe module uses –48 VDC power, which is provided through

TimeAnalyzer’s power distribution panel.

TimeProvider 500 Client Module

The TimeProvider 500 (TP500) client module shown in Figure 1-7 provides a

client-clock function with the ability to synchronize to a grandmaster clock. To

perform the client-clock function, the TimeProvider 500 uses IEEE-1588 v2 as a

frequency reference to steer either T1 or E1 frequency outputs. The TP500 client

module can be configured and monitored using the Command-Line Interface (CLI)

accessible locally with the RS232 connection or remotely via a Telnet connection.

The TP500 Client module “translates” IEEE 1588v2 packet flow into two T1/E1

signaling outputs (G.823/G.824). The TimeProvider 500 PTP translation function

enables legacy Time-Division Multiplexing (TDM)-based devices to transparently

send and receive critical timing and synchronization signals over a packet-based,

Ethernet backhaul network without requiring any modifications to their existing

hardware or software. TimeProvider 500 is fully interoperable with Symmetricom’s

TimeProvider 5000, TimeHub, and SSU 2000 IEEE 1588v2 grandmaster products,

as well as third-party grandmaster products that comply with the IEEE 1588v2

protocol standard.

Warning: To avoid serious personal injury or death, exercise caution

when working near high voltage lines and follow local building

electrical codes for grounding the chassis.

Figure 1-8. TP500 Module Connections

Power Connector

A Molex-style connector is used to provide -48 volts DC (labeled Power). When the

unit is successfully powered, the PWR LED near the left side of this panel will

illuminate green. If the power connection is reversed, the unit will not be damaged, it

simply will not power-up. Startup power will be < 17 watts. Steady-state power

(nominal 25° C) <9.5 watts. The TP500 Client module uses –48 VDC power and is

not equipped with a power switch. Power to the unit is controlled by TimeAnalyzer’s

DC power supply.

RJ48C Connectors

The stack of 2 RJ48C connections labeled SPAN1 and SPAN2 (can use standard

Ethernet cable) provides two separately driven output signals, configurable as either

E1 or T1. These are differential outputs (tip and ring) conforming to signal levels

defined in G.703.

Warning: To avoid serious personal injury or death, exercise caution

when working near high voltage lines and follow local building

electrical codes for grounding the TimeAnalyzer

Note: The RJ48C physical connector is the same as RJ45 (an 8-pin

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

RJ48C is used for 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.

TimeProvider 500 Client Module

T1/E1 Frequency Output Connectors

The TP500 Client module provides configurable outputs at either E1 (2.048MHz) or

T1 (1.544MHz) frequencies. Specific signal types at each frequency are detailed in

the CLI command, set output signaltype, as described in. Both outputs must be the

same signal type. There are two independent, separately driven outputs, labeled

SPAN1 and SPAN2. For differential connection to the TP500 Client moduleeither

output, use the appropriate RJ-48C connection shown in Figure 1-8. SPAN1 is the

upper connection and SPAN2 is the lower connection. For single-ended connection

to either output, use the BNC connectors shown in Figure 1-8.

LEDs

At the center are four LEDs:

 PWR illuminates green when the unit is powered.

 SYNC provides high-level status indication. The indications and associated

meanings are described later in this document.

 OUT illuminates green when output is being generated on the SPAN

connections.

 ALARM illuminates Red to indicate a CRITICAL or MAJOR active alarm, AMBER

to indicate MINOR alarm. Current alarm status can be checked using the show

alarm command. For more information, see the CLI command, show alarm, in

the TP500 User’s Guide.

RS232 MGMT Serial Port

The DE9 connector labeled RS232 MGMT provides a local serial connection to the

TP500 module. Through this connection, a Command Line Interface (CLI) provides

configuration and status monitoring capability. The RS-232 serial port connection is

made through a DE9S female connector. This port allows you to connect to a

computer using terminal emulation software for remote monitoring an control. When

connecting to this port, use a shielded direct connect cable. See Provisioning the

TP500 PTP Client Module, on page 77, for default settings.

IEEE 1588 Remote Management Port

The RJ-45 connector labeled “1588” is the connection into the network that is

providing the grandmaster clock(s). This same connection is also used for remote

management.

Note: The outputs from the left BNC and lower RJ48C connection

(both labeled SPAN1) are generated from the same driver circuit, so

for proper signal level only one of those connections should be used

at any one time. The same situation applies to the right BNC and

upper RJ48C, both labeled SPAN2.

TimeWatch Probe Module (TA 7500 only)

TimeAnalyzer 7500 includes the TimeWatch probe module, which is designed to

perform an MRTIE measurement between two external clock inputs. The inputs are

independent and each can be either a 2.048 MHz clock or an E1 2.048 Mbit/s

signal. The probe module uses an internal TIE measurement engine that compares

two external inputs at 80 samples per second (80Hz) and calculates the relative

phase. This data is averaged to produce one TIE value for each second, this is then

used to calculate the MRTIE between the two inputs.

The calculated MRTIE is a worst case MRTIE from the start of the measurement

period which begins at probe initialization and is restarted if the mask is exceeded.

The computed MRTIE is compared against the chosen mask, and an exception is

generated if the mask is exceeded. The probe module’s firmware handles

communications with the attached PC application, whether TimeMonitor Watch or a

terminal, formats and then streams the live TIE measurement data directly to the

application. The application can then be used to view, store and further analyze the

measurement data.

Figure 1-9. TimeWatch Probe Module Front Panel

TimeWatch Probe Module Connections (TA 7500 only)

The probe module’s front-panel connectors are as follows:

Measure In (BNC)

M(R)TIE is computed on the relative phase between this input and the Ref In input .

The interface must be configured to be a full height 2.048Mbit/s (G.703 sec. 9), a

30dB down 2.048Mbit/s signal (G.703 sec. 9) or a 2.048MHz signal (G.703 sec. 13).

Ref In (BNC)

This input is used for the input of a reference clock signal. MRTIE is computed on

the relative phase between this input and the Measure In interface. The interface

must be configured to be a full height 2.048Mbit/s (G.703 sec. 9), a 30dB down

2.048Mbit/s signal (G.703 sec. 9) or a 2.048MHz signal (G.703 sec. 13).

Aux Out (BNC)

Can optionally provide a buffered copy of the Ref In signal; this interface can only be

used if the Ref In interface is a 2.048MHz signal.

PSTN Analogue Modem (RJ11)

This connector is used for connecting the probe to a PSTN network for

communication with the server. An optional internal PSTN modem must be installed

to enable this option. N/A for implementation in TimeAnalyzer.

LAN (RJ45)

This connector is used for connecting the probe to an Ethernet network to enable

communication with the server. It is available on all TimeWatch variants. The probe

will automatically detect the data rate of the network; however it may be necessary

to configure other network parameters before normal operation. This port will

auto-negotiate and run at speeds of either 10 or 100BASE-T.

Alarm Relay Contact

This interface uses a three pin terminal block with Normally Open, Common and

Normally Closed pins. It can optionally be connected to an external alarm

management system. If an MTIE exception occurs, the relays will be switched and

will remain in the active state until a minimum of 15 minutes after MTIE is within the

configured mask. The relay will also be in its alarm state if power fails to the probe

or if any hardware fault is detected, for example loss of Measure In signal.

Power (-48vDC)

This is the power supply connector and has four pins. Pin 1 is the positive voltage

V+, nominally 0V; pin 2 is the negative voltage, nominally -48V; pin 3 is ground; pin

4 is unused. Power is provided from TimeAnalyzer’s power distribution panel.
