Chapter 1 Overview of the TimeProvider

Overview

Overview

The TimeProvider is Synchronization Supply Unit (SSU) designed specifically to
meet the needs at the network edge. In small offices where core office
synchronization solutions are critical, an edge clock like the TimeProvider is ideal
because of its compact size and flexibility. Using the integrated GPS features, you
can use the TimeProvider in a “small” Central Office to act as a Primary Reference
Source (PRS).

The TimeProvider’s unique design incorporates the input, output, and clock
functions in a single card, available with either a Rubidium or quartz oscillator. This
allows you to simplify the storage inventory required for future expansion needs.
The TimeProvider shelf requires only three plug-in cards to operate with full
redundancy: dual Input/Output/Clock cards (IOCs) and a single Information
Management Card (IMC), which serves as a communications/alarm interface.
When dual IOCs are installed, you can mix any combination of Rubidium and quartz
oscillators (for example, Rb/Rb, Rb/Qz, or Qz/Qz) to the needs of the network. The
main shelf provides up to 32 redundant universal timing outputs; an optional
Expansion Panel provides an additional 32 redundant outputs.

Using Symmetricom’s SmartClock™ technology design, the oscillators within the
IOCs are enhanced with improved performance and accuracy. Using intelligent
firmware algorithms, SmartClock “learns” the effects of t he ageing of the clock while
it is locked to a reference signal and stores this information in its memory. If the
reference signals are lost or disqualified, SmartClock uses the stored data to
compensate for frequency changes while the TimeProvider continues to distribute
highly stable synchronization signals.

The TimeProvider also uses Symmetricom’s BesTime

®

algorithm when the GPS
input is activated. By using other inputs as references, Bestime calculates and
determines a weighting factor for each of the inputs and ensembles them in the
overall timing scheme to provide very accurate timing outputs. In the event of GPS
signal loss, BesTime continues to predict GPS timing info rmation to provide reliable
system timing outputs and holdover performance, ensuring that system reliability is
maintained. See BesTime, on page 43 for more information.

Shelves

The TimeProvider is available in two shelf models. Each shelf supports up to 32
redundant output channels.

 The TimeProvider 1000 is a 175 mm tall ETSI shelf that meets the requirements

of ETSI 300 1 19-4 January 1994 . Figure 1-1 shows the TimeProvider 1000 shelf.

 The TimeProvider 1100 is a 130 mm tall rear-access shelf; indicators are on the

front panel and connections are available on the rear panel. Figure 1-2 shows the
front panel of the TimeProvider 1100.

Expansion Panel

The TimeProvider has an optional Exp ansion Panel that d oubles (to 64) the number
of output channels available. Figure 1-3 shows the rear-access version of the
Expansion Panel. The Expansion Panel receives timing signals from the
TimeProvider main shelf through an expansion cable. The Expansion Panel
provides four groups (A through D) of eight signals; each group is automatically
provisioned to the same output signal type as the corresponding group on the main
shelf.

Inputs

The TimeProvider accepts the following types of input signals:

 Primary Reference Signals (PRS): 1.544 MHz, 2.048 MHz, 5 MHz, 6.312 MHz, or

10 MHz

 Span input signals:

– E1 or 2.048 MHz analog; user-selectable CAS or CCS framing
– T1 D4, Extended Superframe (ESF)
– 1.544 and 6.312 MHz
– Composite Clock, including Japan Composite Clock (JCC) and Japan

Composite Clock with 400 Hz (JCC4) signals

 GPS input:

– GPS signal from the stand-alone TimeProvider Interface Unit (TPIU)
– GPS signal into the TPIU integrated with the IMC (IMC/TPIU card)

The TimeProvider qualifies the input reference signals and detects the following
errors: Loss of Signal (LOS), Alarm Indication Signal (AIS), Loss of Framing, and
Synchronization Status Messages (SSM) where applicable. Reference Input

Signals, on page 34, describes the inputs in more detail.

Outputs

The TimeProvider produces a variety of outputs to meet different signal standards.
Output signal types include 8 kHz, 1.544 MHz, 2.048 MHz, 6.312 MHz, E1, T1, CC,
JCC, JCC4, and TIA/EIA-B-422 (1.544 and 2.048 MHz). The E1 and T1 signals can
be provisioned with standard framing that meets G.703 formats. The SSM bit
location is user-selectable on E1 outputs; CRC4 mu st be enabled in order to provide
output SSMs. These outputs are available through one of several different
connector panels. See Output Signals, on page 39, for more information on output
signals.

22 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008

Chapter 1 Overview of the TimeProvider

The TimeProvider outputs are arranged into four groups of eight outputs per group
in the Main shelf and four groups of eight outputs per group in the optional
Expansion panel. Each group is labeled A, B, C, and D, and can be configured
independently.

Operating Modes

Communication

Three communications ports provide access to the TimeProvider: Ethernet, local
Craft serial port, and a Remote serial port. These ports are described in detail in

Communication Ports, on page 34.

Clocks

The TimeProvid er’s clock design includes a highly stable ovenized Quart z crystal or
Rubidium oscillator with Direct Digital Synthesis (DDS) to produce accurate
synchronization outputs. In a dual-IOC configuration, the clock function is redunda nt
to provide protection, and you can mix and choose any combination of Quartz and
Rubidium oscillator to meet the needs of the network. Each IOC qualifies the input
signal and filters jitter and wander noise elements that may exist. In the event that
all input references are lost or disqualified, the TimeProvider’s clock design,
together with the SmartClock technology, goes into holdover mode with the
oscillator providing the system reference.

The Rubidium IOC meets Stratum 2/Type II performance; the Quartz IOC meets
Stratum 3E/Type I performance.

Operating Modes

You can configure the TimeProvider to operate in one of three modes:
Synchronization Supply Unit (SSU), Subtending (SUB) as defined by Telcordia
GR-378 Section 7, or Primary Reference Receiver (PRR) when the GPS input is
available. Each mode is unique in its operation, and is defined in the following
paragraphs.

SSU Mode

This is the TimeProvider’s default operating mode. You can select the system
reference from any valid input on the PRS, INP1, INP2, or GPS connectors.

The GPS input operates as another input reference to the TimeProvider and is
treated in the same manner as all other input references (PRS, INP1, or INP2). If
the GPS input is active but later becomes disqualified, then the TimeProvider
switches to the next available input reference according to the switching rules
(Priority, SSM, etc.). If there are no other qualified inputs, then the TimeProvider
enters the holdover state until an input is requalified.

097-58001-02 Revision G – April 2008 TimeProvider User’s Guide 23

Chapter 1 Overview of the TimeProvider

Performance Monitoring

In the SSU mode, the INP1 and INP2 inputs cannot be provisioned to receive
Composite Clock (CC) signals, including JCC or JCC4. The method of selecting the
system reference is described in Selecting the Input, on page 35.

SUB Mode

This mode allows the TimeProvider to operate as a Remote shelf where phase is
critical. When you select the SUB mode, INP1 and INP2 are automatically set for
CC inputs (including JCC and JCC4). Outputs provisioned for CC are phase-aligned
with the selected CC input reference. Other output types comply with G.703 and
GR-1244.

To configure the TimeProvider for Subtending mode, see Setting the System Mode,
on page 105.

PRR Mode

In PRR mode, the GPS is automatically selected as the system reference input.
This requires that you connect a GPS signal to the TimeProvider through either:

 the standalone TPIU (used with Antenna Kits 990-58545-01 or 990-58545-02) or
 the integrated IMC/TPIU card (used with Antenna Kits 990-58545-03 or

990-58545-04)

This mode complies with ITU-T G.811 and Telcordia GR-2830 requirements for
Primary Reference Receivers/Clocks. Valid signals on the PRS, INP1, or INP2
connectors are used in conjunction with BesTime to extend compliance with
GR-2830/G.811 standards.

The PRR mode uses Symmetricom’s BesTime servo control that allows the
TimeProvider to continue providing outputs in case GPS tracking is lost, the GPS
data loses integrity, or if the IMC is removed from the shelf. BesTime, on page 43
provides more information on the BesTime technology.

To configure the TimeProvider for PRR mode, see Setting the System Mode, on
page 105.

Performance Monitoring

The TimeProvider can monitor a nd qualify all enabled input signals based on phase
measurements. It measures the phase differences between the inputs and the
output of the corrected clock. From these phase measurements, the TimeProvider
computes frequency offset and wander of the input signals. Wander is reported in
terms of Maximum Time Interval Error (MTIE) and Time Deviation (TDEV) and
creates phase, MTIE, TDEV, and Fractional Frequency Offset (FFOFF) reports.
Performance data is automatically gathered on all enabled or monitored inputs.

24 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008

Chapter 1 Overview of the TimeProvider

Using MTIE and FFOFF data, the TimeProvider qualifies inputs based on these
metrics. You can specify thresholds to disqualify inputs and generate corresponding
alarms, causing the TimeProvider to switch references or enter the Holdover mode.

For more information on performance monitoring, see Using Performance

Monitoring, on page 116. The TimeProvider TL1 Reference Guide contains a

section describing the TL1 commands related to performance monitoring.

Performance Monitoring

Phase Measurements

The IOC measures and transfers 1-second phase data with 100 ns resolution from
each enabled input to the IMC or IMC/TPIU every 10 seconds. This phase data is
averaged to a 1 ns resolution, which is used to produce a 1-minute phase data
sample. The 1 ns data sample is the basis for MTIE, TDEV, and FFOFF
calculations. The phase data is not used to qualify an input reference source.

TL1 commands are available to display the 60 most recent phase data (at 100 pS
resolution) measurements, the previous 86400 1 ns data averages, and the
previous 10080 samples of 1-minute 1 ns-resolution data.

MTIE Calculations

MTIE is a measure of the relative noisiness of an input signal that relates to
frequency offsets and phase transients. The TimeProvider automatically calculates
MTIE for each enabled input from the 600 most recent 1-second phase updates.
From this calculation, you can retrieve MTIE values for 1, 5, 10, 50, 100, and
500-second windows. You can set an alarm threshold for each of these windows; if
the MTIE value exceeds this threshold and the alarm level is set to Minor or higher,
the TimeProvider generates an alarm.

You can use the automatic MTIE calculations to qualify each input with user-defined
qualification thresholds. If an input exceeds the threshold, then the input reference
automatically switches to the next-best input.

You can also set thresholds using pre-defined masks according to ANSI T1.101 (for
PRS inputs), ITU-T G.811 (for PRC input s), or ITU-T G.812 (for Type I and T ype II/III
inputs). The TimeProvider performs a second MTIE calculation using the previous
24-hour period; this calculation is not used to qualify inputs.

TDEV Calculations

TDEV is a measure of the relative noisiness of an input signal that relates to its
spectral content. The TDEV for each enabled input is automatically calculated from
the previous 24-hour period. The TDEV value is used for monitoring only and is not
used for qualifying an input signal.

You can retrieve the TDEV values for the following integration times: 1, 5, 10, 100,
500, 1000, 5000, and 7200 (84000/12) seconds.

097-58001-02 Revision G – April 2008 TimeProvider User’s Guide 25

Chapter 1 Overview of the TimeProvider

NTP Operation

FFOFF Calculations

FFOFF is a measure of the frequency deviation of the input signal against the
system reference, expressed as a ratio. The TimeProvider automatically calculates
FFOFF for each enabled input from the 600 most recent 1-second phase updates.

You can use the automatic FFOFF calculations to qualify each input with
user-defined qualification thresholds. If an input exceeds the threshold and the
alarm level is set to Minor or higher, then the input reference automatically switches
to the next-best input.

The TimeProvider stores historical FFOFF measurements for each enabled input
every 60 seconds. You can retrieve FFOFF data for the prior 24 hours, depending
on the number of faults that have occurred.

NTP Operation

The Network Timing Protocol (NTP) function is implemented in the IMC card or
IMC/TPIU card. You can activate the NTP feature by issuing a unique key
generated by Symmetricom, based on the serial number of the IMC card or the
IMC/TPIU card, or you can order the TimeProvider with the NTP option factory­installed and activated. Once activated, the NTP function cannot be deactivated.

NTP operates in all three operating modes of the TimeProvider. In the Subtending
mode, the NTP server is supported when the system reference is a signal other
than GPS. The NTP data is transmitted by the Ethe rnet port on the shelf, and meets
the following standards and specifications:

 NTP V3
 MD5 Authentication (RFC 1321)
 NTP Leap Second correction based on GPS
 NTP supports a 10baseT connection under a 40% loading condition, and can

handle up to 100 requests per second (RPS) on average

 Typical unencrypted response time from the TimeProvider on an unloaded

network is < 10 ms

 Typical encrypted (MD5) response time from the TimeProvider on an unloaded

network is < 50 ms

 The client time accuracy is typically 2 ms between the internal NTP clocks of two

machines on the same 10 Mb/s Ethernet LAN with a 40% loading condition

Note: NTP over a LAN topology depends on network conge stion, and
can be up to 50 ms accuracy.

26 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008

Chapter 1 Overview of the TimeProvider

NTP Operation

The NTP implementation in the Ti meProvider supports full NTP server and client
mode operations, and works with or without GPS reference signals. The
TimeProvider supports the following NTP modes:

 Mode 1: GPS available, Server mode – The NTP application defaults to GPS as

the master time reference; only NTP Server mode is supported.

 Mode 2: GPS available, No Client mode – NTP Client mode is not supported

when GPS is available; only NTP Server mode is supported.

 Mode 3: GPS not available, Client mode – When GPS is not available, the

TimeProvider will go into client mode to search for time references from
user-programmed timeservers with valid IP addresses.

The user can input up to eight IP addresses of other timeservers. If there are
multiple timeservers, the TimeProvider performs an ensembling of all the
timeservers to determine the system time based on the averaging of all the
valid timeservers. The user can also manually select which of the timeservers
available to be the prime. The user can set how often to request an update
from each individual timeserver from the eight IP addresses, ranging from 16
seconds to 1024 seconds, incrementing in powers of 2.

At any instance in client mode, the time reference within the TimeProvider is
totally derived from the ensembling of the timeservers, and is not reliant on
the IOC for time ticks.

 Mode 4: GPS not available, Server mode – The TimeProvider can be enabled or

disabled for server mode operation. This mode is supported o nly when the Client
mode has found and validated the time stamp from the ensembling of the
timeservers.

MD5 authentication is included in the NTP implementation. The user can enable or
disable the MD5 feature, and is available in server and client modes. Client
configuration for MD5 operation requires Server IP, MD5 Authentication Key, and
Key ID.

The user can enter an MD5 Authentication Key of up to 32 ASCII characters that is
not case-sensitive. In addition, there is also a key ID ranging from 0 to 65534 in the
MD5 authentication process. When MD5 is enabled and a client requests NTP
information but the MD5 key cannot be authenticated or is missing the MD5 key
altogether in the request, then the TimeProvider does not process the client’s
request. The TimeProvider does not provide any response or events in these two
scenarios.

If MD5 is disabled, a client request is returned with the proper NTP time stamp
regardless of whether the client has an MD5 key attached in the request.

Chapter 1 Overview of the TimeProvider

SNMP – Simple Network Management Protocol

SNMP – Simple Network Management Protocol

The TimeProvider offers two versions of SNMP: v2 and v3. SNMP v3 software
offers additional security with authentication and privacy parameters. The security
feature allows secure transactions to provide protection against modification of
information, masquerade, and message stream modification.

Simple Network Management Protocol (SNMP) is based on a client-server
query-response mode. A manager is the client generating the queries, while an
agent is the server generating the responses.

The TimeProvider SNMP is an SNMP agent that requires Ethernet connectivity. If
SNMP is present, port 161 becomes the port of standard SNMP interactive
communications, while port 162 becomes the trap port. Since the TimeProvider
SNMP supports all existing functions, full system control of the TimeProvider is
maintained through SNMP.

The TimeProvider implements an SNMP agent. A Management Information Base
(MIB) browser or the SNMP Manager is used to access, retrieve, and query
information defined by the MIB.

All reports, queries, autonomous messages, control, provisioning, and administration
(except for communication port parameters, Set User ID/Password, Set IP
assignments, Reset connection, and SNMP community settings) are available
through SNMP. Refer to
information.

Physical Description

The TimeProvider consists of a shelf, plug-in cards, connector adapter panels for
the cards, cables, hardware, and software. The TimeProvider is available in two
configurations: front access (Model 1000) and rear access (Model 1100), as shown
in Figure 1-1 and Figure 1-2.

Figure 1-4 illustrates the location of the connectors, cards, and modules in the
