Module 13 - TimeProvider 5000 Overview


2/43

The TimeProvider 5000 is a Next Generation Network (NGN) packet-based

timing and frequency device that combines the functionality of a highly-

accurate, IEEE 1588 v2 Grand Master Clock with T1/E1 and 1PPS/10MHzI/O ports.

What is the TimeProvider 5000?

• The primary application for the TP 5000 is to provide frequency

synchronization over Ethernet through the use of PTP/IEEE 1588

• One of the main drivers for this technology is to accommodate the

growth in wireless network traffic at a lower cost than traditional TDM

backhaul.

• Some IP addresses are reserved (set intra-system)

• Also contains serial comms, timing signals

• Cards are hot-swappable

• -48V is distributed to IOC and IMC cards• Active IOC

• Active IOC drives signals on I/O module

• Active IOC controls timing for chassis



25/43

TP5000 Capacity

• Each IOC card has two Ethernet ports. They can be set in bonding

mode as a redundant port or set to Active/Active.

• In bonding mode, Eth1 configurations and settings will be used.

• If the two ports are set to Active/Active, they must reside on twodifferent subnets.

• The TP5000 supports up to 500 unicast clients per Active port.



26/43

TP5000 Capacity

• Each port can support up to 500 clients

• Each port can support up to 17000 pkts/sec

• Announce, sync, delay packets

• These limits are doubled if ports are independent

• Also have limit on other packets

• Get “excessive traffic alarm” if exceeded• Could be from attack or excessive signaling pkts

• Each client should not negotiate more often than every 10 seconds

(lease default should be 300 sec)



27/43

PTP Message Rates

Message Range

Announce 3 (1 pkt/8s) to -3 (8 pkts/s)

Sync 7 (1 pkt/128s) to -7 (128 pkts/s)

Delay Req/Resp 7 (1 pkt/128s) to -7 (128 pkts/s)

The time interval in PTP Messages is represented as the logarithm to the base 2

in seconds.

For example:

Interval = 7 1 Messages every 128 seconds

Interval = 3 1 Messages every 8 secondsInterval = 1 1 Message every 2 seconds

Interval = 0 1 Message every second

Interval = -1 2 Messages every second





28/43

TP5000 Performance

• The TP5000 support 100/1000BT Full Duplex.

• For best performance with clients, both the Grandmaster and clients

should be run at the same speed.

“Bonding”• The active port’s configuration is shared for both the active and

standby port

• This includes the IP address and MAC Address



31/43

Port Redundancy

Requirements for card

and port redundancy:• Port protection is

enabled

• All ports must have

the same IP address

32/43

Card Redundancy

• One card is active and drives outputs

• If card fails, other card takes over

• Will also switch on loss of Ethernet

• Switchover in less than 10 seconds

• Send gratuitous ARP after switchover

• PTP flow automatically continues• Characteristics

• I/O module outputs – smooth transition

• Ethernet outputs – lose packets for several seconds

• Manual switchover also supported



33/43

Card Redundancy

• Neither card is primary

• On system power-up, IOC1 will be active• After initial warm-up, Rb IOC will be active

• Switchover is non-revertive

• Both cards share same configuration (IOC1)

• Configuration and state is synched betweencards automatically

• Addresses

• Same IP address on both cards

• MAC address is different for each card• Default for 1.1 – card redundancy on, port redundancy off

• Independent cards are NOT supported



34/43

Card Redundancy


redundancy:• Two IOC cards

Shelf Modes of Operation

• Grandmaster

• Primary source of PTP timing packets to be distributed on thenetwork

• TimeAnalyzer (probe) mode

• The 5000 is used to monitor incoming PTP packets to monitor and

record performance.



37/43

Reference Modes/TimeScales

Auto Timescale (default and recommended)

• Will automatically switch between PTP and ARB depending on

what the input is.

• System will always use PTP mode if GPS is connected and

functioning

PTP Timescale (GPS mode)

• The mode used when locked onto GPS

ARB Timescale (System mode)• This mode is used when a E1/T1 reference is being used or when

the system is in Free-run



38/43


39/43

IOC/IMC Time Synchronization

The IMC and IOC modules communicate with each other through

Ethernet communications.

• The system assigns a range of IP addresses that the modulescan use

• The IP address range can be changed by the user.

The ranges are:

• A: IP address range 10.0.250.8 to 10.0.250.47

• B: IP address range 172.16.250.8 to 172.16.250.47

• C: IP address range 192.168.250.8 to 192.168.250.47

• These addresses can't be used for external Ethernet ports.



40/43

VLAN’s

• The TP5000 supports up to 16 VLAN’s

• Each VLAN must have its own address and

subnet.

• There is no default VLAN configuration, itmust be configured.

• VLAN is supported while using both Port

and Card redundancy



41/43

Backup and Restore

The TimeProvider 5000 has the ability to:

• Backup the current configuration to non-volatile memory• Restore the saved configuration from memory

• Revert the system to factory defaults



42/43

SNMP

• Simple Network Management Protocol (SNMP) is an application layer

protocol that allows you to manage network devices.

• The TimeProvider 5000 supports both SNMPv2c and SNMPv3.

• If SNMP is present, port 161 becomes the port of standard SNMP

interactive communications and port 162 becomes the trap port.

• SNMP is an optional feature for the TP5000 that must be enabled to

function.

• Can either be ordered in a new system, or added to a previouslyordered system as a field upgrade.



43/43

Security

• Standard user access list with three levels of access

• User

• Config

• Admin

• The TimeProvider 5000 supports RADIUS authentication

• The system must be configured in order to use this feature

• The TP5000 allows local login, even if RADIUS loginauthentication is enabled
