System Release Notice

TimeProvider 500IEEE 1588v2 Translator

Introduction

Thank you for choosing Symmetricom as your telecommunications timing and synchronization

solutions provider.

This Software Release Notice (SRN) describes the key features and known issues associated

with the revision 2.0.7 of the TimeProvider 500 IEEE 1588v2 Translator.

Product Overview

The TimeProvider 500 is a standalone IEEE 1588v2 Precision Timing Protocol (PTP) translator

product that enables rapid migration from TDM-based to packet-based timing and

synchronization solutions.

TimeProvider 500 is fully interoperable with Symmetricoms 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.

include:

Hardware Features:

1 Rack Unit (RU) Package

Dual -48 VDC Power Input Connectors

OXCO Oscillator

Integrated 100 Mbps PTP Network Port and Ethernet Management Port

Dual T1/E1 BNC and RJ48 Output Ports

Bookend Solution with Symmetricoms PTP-System Blades and TimeProvider 5000

Grandmaster Products

Software Features:

PTP to E1/T1, 1PPS, and 10 MHz Signal Translation

Improved Performance from Version 1.0

Auto-Negotiated Unicast

Multiple VLAN Support

PTP Performance Metrics

Command Line Interface (CLI)

Multicast (hybrid) PTP

PTP Management via TimeProvider 5000 Proxy, including Alarms

DHCP

TOD Messages on Serial Port

Notes:

Serial port settings are: 57600 baud, 8N1, Flow Control None.

Default values are: admi n(user name), symmadmi n** (password), and 192. 168. 1. 9 (IP

address).

After configuring IP and VLAN parameters, it is recommended that the settings be verified

with the showi nt erf aceconf i gCLI command.

Changing PTP packet flow configurations will result in a brief flow alarm.

There is some coupling for outputs. See the output connector section in the Overviewchapter of the TimeProvider 500 2.0 User Guidefor output coupling information.

When changing the grandmaster attachment from one interface to another, disable PTP first

(using the set pt p addr - mode di sabl eCLI command), change the attachment, and then

enable PTP after the attachment change. If PTP is not disabled, communication may not be

re-established between the grandmaster and the TimeProvider 500.

To view the current product number, firmware version, and product serial number, use the

showi nvent or yCLI command.

The pulse width factory default is 500 ns when running on 090-03863-01 hardware. For an

optimum pulse shape on the 090-03863-01 hardware, the pulse width should be set to 500 ns

(default value) or less.

When switching from unicast to multicast and there is no multicast master, delay requests will

continue to be sent to the unicast grandmaster until the unicast lease expires.

Do not attempt to load 1.0 firmware on a unit that is running 2.0 or higher firmware. This type

of firmware loading is not supported.

When upgrading firmware, only lowercase file names are supported; including directory paths

and usernames.

Please consult the TimeProvider 500 2.0 User Guide(098-00172-000) for detailed descriptions

of the features listed above.

Upgrading from Version 1.0 Firmware

When upgrading from version 1.0 firmware, to any revision of the 2.0 firmware, non-volatile

settings are preserved. See Appendix C of the TimeProvider 500 2.0 Users Guidefor acomparison of the 1.0 CLI commands with updated and new 2.0 CLI commands.

Known Issues

24240: Prolonged flooding of the TimeProvider 500 with non-sync packets may cause a

reboot.

Workaround:Assure that the TimeProvider 500 is filtered so that non-sync packets are not

sent to the units IP address.

25441: The TimeProvider 500 reads the leap second pending flags from the sync message

rather than from the announce message. This could cause the UTC time to be incorrect for a

short time after a leap second event.

Workaround: Some grandmasters set the leap pending flag in the sync message. The time

will correct within 30 seconds of a leap second event.
