Chapter 1 Overview of the TimeProvider
Overview
20 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008
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 the 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 information 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 300 119-4 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 Expansion Panel that doubles (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.

Figure 1-3. TimeProvider 1100 Expansion Panel
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 must 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.
097-58001-02 Revision G – April 2008 TimeProvider User’s Guide 23
Chapter 1 Overview of the TimeProvider
Operating Modes
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.
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 TimeProvider’s clock design includes a highly stable ovenized Quartz crystal or
Rubidium oscillator with Direct Digital Synthesis (DDS) to produce accurate
synchronization outputs. In a dual-IOC configuration, the clock function is redundant
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.
Chapter 1 Overview of the TimeProvider
Performance Monitoring
24 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008
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 and 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.
097-58001-02 Revision G – April 2008 TimeProvider User’s Guide 25
Chapter 1 Overview of the TimeProvider
Performance Monitoring
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.
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 inputs), or ITU-T G.812 (for Type I and Type 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.
Chapter 1 Overview of the TimeProvider
NTP Operation
26 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008
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 factory-
installed 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 Ethernet 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 congestion, and
can be up to 50 ms accuracy.
097-58001-02 Revision G – April 2008 TimeProvider User’s Guide 27
Chapter 1 Overview of the TimeProvider
NTP Operation
The NTP implementation in the TimeProvider 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 only 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
28 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008
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
the TimeProvider TL1 Reference Guide
for more
information.

Shelf
Both the front-access and rear-access shelf provides a chassis for mounting the
Input module, one IMC or one IMC/TPIU, two IOCs, and up to four Output modules.
A backplane provides connections between the modules.
Input Module
The Input module receives the incoming reference signals and contains the alarm
input/output connector. A variety of connector modules allows you to select the
connector style and input impedance to match the wiring system at the installation
site.
Information Management Card (IMC)
The Information Management Card, known as the IMC, contains a processor that
manages communications between the two IOCs and the serial and Ethernet
communications ports. It also provides communication to the GPS receiver in the
antenna; if the IMC fails or is removed, GPS operations cease.
Chapter 1 Overview of the TimeProvider
Functional Description
32 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008
Integrated Information Management Card with TimeProvider Interface Unit
(IMC/TPIU)
For users who use the GPS feature, the integrated IMC/TPIU combines the features
of the IMC card with the TPIU into the same size footprint as a stand-alone IMC
card (see the descriptions of the IMC and TPIU). The IMC/TPIU reduces rack space
requirements by eliminating the rack mounted stand-alone TPIU. Functionally, the
IMC/TPIU supports the same functions as the IMC card, controlling all
communication channels within the TimeProvider and managing GPS control
processes. If the IMC/TPIU fails or is removed, GPS operations cease.
Input/Output and Clock Module (IOC)
The TimeProvider operates with one or two IOCs. A second IOC in the shelf
provides protection should the primary IOC fail. The IOC accepts the incoming
reference signal and decodes the SSM, if present.
With the system properly provisioned and a reference signal selected, the local
oscillator in the IOC operates in one of the following states:
Warm-up – For up to 20 minutes after applying power to the shelf, the IOC
operates in warm-up mode.
Fast-lock – After warm-up is complete, the IOC enters the fast-lock state, where it
quickly frequency-locks the local oscillator to the reference input.
Normal lock – After the IOC has completed the fast-lock cycle, it enters the
normal lock mode, in which the TimeProvider uses the proper amount of filtering
for the selected mode. When set to the SSU mode and locked to an active input
traceable to a Primary Reference Source (PRS), the TimeProvider complies with
the G.811 and GR-2830-CORE standards.
Holdover – If the reference signal is lost, then the clock enters the holdover
mode. The accuracy of the TimeProvider output is then dependent on the quality
level of the oscillator in the IOC.
Free-run – If the IOC starts without a system reference, the TimeProvider enters
the free-run state after warm-up. If a reference is applied, then the TimeProvider
enters the fast-lock and then the normal-lock states.
Bridging – In the event that all input references are lost, the TimeProvider goes
into the bridging mode where the outputs continue to provide accurate timing
outputs for a user-defined amount of time. If the inputs have not been requalified
before the bridging time has elapsed, then the TimeProvider enters the holdover
mode.
After the IOC has been in the Normal lock mode for at least three days, SmartClock
holdover mode becomes available. Compared to the normal holdover mode, this
mode provides a superior output quality.

Chapter 1 Overview of the TimeProvider
System Power
Output Module
The Output module provides the output connectors for the TimeProvider. Like the
Input module, each Output module uses one of a variety of connectors that match
the wiring system at the installation site. Making Output Connections, on page 66,
describes the Output Modules available for the TimeProvider and the Expansion
Panel.
Expansion Panel
The Expansion Panel provides up to 32 additional outputs that the TimeProvider
can generate. See Expansion Panel, on page 21 and Rack Mounting, on page 56
for more information.
TimeProvider Interface Unit
The TimeProvider Interface Unit (TPIU) provides power, communication, and a
composite timing reference signal between the antenna and the TimeProvider main
shelf. The TPIU is an external, stand-alone rack mounted assembly included in
Antenna Kits 990-58545-01 and 990-58545-02. The TPIU can be used only with
IMC card 090-58031-01. During antenna installation, you can use the LEDs on the
TPIU to detail the status of the received power and antenna communication. See
Making GPS Connections, on page 71 for more information.
System Power
The TimeProvider main shelf has redundant –48v DC inputs. The inputs are diode
or’d; in the event that one supply fails, the other takes over. The –48v returns are
isolated from the chassis and circuit grounds. A 5 A fuse on the IOC protects the
TimeProvider; the shelf is protected from damage in case the connections are
reversed.
The power supply range is from –36 to –72 V DC. The power requirements vary
according to the type of IOC installed;
Table 1-1
lists the power requirements.
The procedure for installing power is described in Making Power Connections, on
page 61.

Communication Ports
34 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008
Communication Ports
The TimeProvider contains three communications ports that allow you to provision,
monitor, and troubleshoot the shelf. The Ethernet and Remote serial ports are
located on the shelf, and the local Craft serial port is located on the IMC. You
communicate with the TimeProvider using the TL1 protocol.
You can select one of four security levels for each user; each level has varying
levels of access to provisioning parameters. See Defining the Security Parameters,
on page 94.
Ethernet
An Ethernet connector provides connectivity to an Ethernet local area network.
Each main shelf has a unique internet protocol (IP) address. Once the IP address is
set and a connection is made to a LAN, you can access the TimeProvider on an
intranet.
The Ethernet port supports up to 10 simultaneous connections to port 5000.
Local Craft Serial Port
This EIA-232 port supports local control; you can configure the TimeProvider with
TL1 commands using a terminal or personal computer (PC) with terminal emulation
software or Symmetricom’s craft software, SynCraft. The connector is located on
the front panel of the IMC or IMC/TPIU card. The default specifications are
9600-8-N-1. The Local port is configured as a DCE interface.
Remote Serial Port
The Remote serial connector can be used in the same manner as the local Craft
serial port. The Remote port has additional control support to manage an external
modem for remote access. The Remote port is configured as a DTE interface.
Reference Input Signals
The Input module accepts one or two E1, 2.048 MHz analog, T1, and Composite
Clock (including JCC and JCC4) inputs on ports INP1 and INP2. The CC inputs are
used solely for Subtending mode; if you provision INP1 or INP2 to a CC type, then
Subtending mode is automatically enabled. You can also connect a 2.048, 5, or 10
MHz or Japan-specific 1.544 MHz or 6.312 MHz input reference signal on the PRS
port. The TimeProvider accepts full-level signals or bridged signals (–20 dB); the
inputs are terminated per G.703. You can also connect a GPS antenna via the
TimeProvider Interface Unit (TPIU) to the GPS Input port on the shelf, or via the
integrated IMC/TPIU card.
097-58001-02 Revision G – April 2008 TimeProvider User’s Guide 35
Chapter 1 Overview of the TimeProvider
Reference Input Signals
Make the input connections using the procedures described in Making Input
Connections, on page 63, then provision the inputs using the software commands
described in Provisioning the Input Reference, on page 108.
Input State
You can provision each input to one of three states:
Disabled – the input is not used
Monitor – the system monitors the input for signal faults and performance data,
but it cannot be selected as the system reference
Enabled – the system monitors the input for signal faults and performance data.
The input can be selected as the system reference in SSU or SUB mode or as a
backup reference in PRR mode.
Selecting the Input
Many considerations influence which system reference you choose:
SSM or User-assigned Quality Level
User-assigned Priority Level
Switching mode
User-assigned Input State
Active alarms on an input
You can provision the TimeProvider to automatically select the highest-quality input
based on priority and performance qualification, or you can manually select the
input signal you want to use. If that signal becomes disqualified for any reason, the
local oscillator goes into the Holdover mode.
Revertive Switching
Telcordia GR-378 and GR-1244 define two reference selection modes: Revertive
and Non-revertive. In the revertive mode, when an input used as the system
reference is disqualified (for any reason), if that input returns, it reverts to the
system reference when the disqualifying reason is removed. The system reference
switches two times: once when the disqualifying event occurs, and again when the
input is no longer disqualified. In the non-revertive mode, the system reference does
not revert to the initial input when the reason for disqualification is removed. The
system reference switches only once when the disqualifying event occurs.
Quality Level and Priority Level
When the REFMODE parameter is provisioned to AUTO, the system reference
switches when the input signal is disqualified. When the input signal is re-qualified,
the TimeProvider can either keep the current reference or switch back to the
re-qualified signal. When the REFMODE parameter is set to FORCED, then the
reference does not switch and remains locked to that reference and the local
oscillator enters Holdover mode if the input is not re-qualified. You may also
Chapter 1 Overview of the TimeProvider
Reference Input Signals
36 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008
provision the REFMODE parameter to FORCED to select an input as the system
reference regardless of the priority levels of other outputs. If this input is lost or is
disqualified, then the REFMODE automatically changes to AUTO and the next
available reference based on priority and QLEVEL becomes the system reference. If
no other input references are available, the TimeProvider enter the Holdover mode.
The QLEVEL (Setting the Input Quality Level, on page 112) and the PRIORITY
(Setting the Input Priority Level, on page 113) parameters work together with SSMs
to determine the switching strategy for the inputs when the unit is in the SSU mode.
If the active/primary input becomes unavailable, the switching strategy determines
which input to use: the TimeProvider uses the input with the next highest QLEVEL.
If all inputs have the same QLEVEL, then the TimeProvider uses the input with the
highest PRIORITY.
To provision the TimeProvider as non-revertive, you must provision the user-assigned
Priority Level on all inputs to the same value. To provision the TimeProvider as
revertive, you provision any one of the inputs to a different Priority Level.
If the original primary input becomes available again, the REFMODE, QLEVEL and
PRIORITY parameters determine whether the TimeProvider switches back to that
input. If REFMODE is set to AUTO, then the reference switches according to the
QLEVEL and PRIORITY settings. If the QLEVEL and/or PRIORITY parameter of
the original input is higher than the current input, the TimeProvider reverts back to
the original input. If the QLEVEL parameter is the same for all inputs, then the
TimeProvider does not revert back to the original input.
SSMs and Quality Level
Synchronization Status Messages (SSMs) can be included in the bit stream of the
incoming signal to indicate its quality level. You must provision the input to read the
SSM, and you must provision the bit position of the incoming SSM.
If the incoming signal does not include SSMs, or if you disable them, then you can
provision the Quality Level to an appropriate value. The QLEVEL value is used in
the same manner as the incoming SSM to determine which input is used when the
active input is disqualified. SSMs are described in more detail in Synchronization
Status Messages (SSMs), on page 41.
SSU Mode
Table 1-2 illustrates which input is the active system reference under several
different input conditions when the TimeProvider is in the SSU mode.

Two IOCs are available:
A Rubidium-based version that meets ST2/Type II standards. This IOC meets or
exceeds the ST2 requirements in ANSI T1.101 and Telcordia GR-1244, as well
as the ITU-T G.812 Type II specification.
A Quartz-based version that meets ST3E/Type I standards. This IOC meets or
exceeds the ST3E requirements in ANSI T1.101 and Telcordia GR-1244, as well
as the ITU-T G.812 TYPE III specification and ITU-T G.812 Type I specification.
Output Signals
The main shelf has 32 output connections arranged in four groups of eight outputs;
each group is labeled A through D. The optional Expansion Panel also has four
groups of eight outputs that correspond to each group in the main shelf; using the
Expansion Panel, the TimeProvider supports up to 64 outputs. The outputs are
“universal:” you can select from E1, 2.048 MHz, T1, 8 kHz, CC, JCC, JCC4, 1.544
MHz, and 6.312 MHz. You can provision E1 and T1 signals with standard framing
and G.703 formats. Additionally, TIA/EIA B-422 (1.544 and 2.048 MHz) output
signals are available using the TIA/EIA B-422 Output module; this module can be
installed only in the main shelf and cannot be installed in the Expansion panel.
The output types provisioned in each group of the Master shelf are automatically
provisioned in the corresponding group of the Expansion panel and cannot be
configured differently.
When you install a Retimer module or a TIA/EIA B-422 Output module in a main
shelf output group, then you can provision the corresponding group in the
Expansion panel to any desired output type.
The TimeProvider uses interchangeable Output modules, allowing you to select the
connector and termination impedance. Output modules are available with the
following connectors and output impedance:
BNC – 75 Ω
DB9 (4 connectors, 2 outputs per connector) – 120 Ω
DB9 (8 connectors, 1 output per connector) – 120 Ω
Metric (Siemens) 1.6/5.6 – 75 Ω
Metric (Siemens) 1.0/2.3 – 75 Ω
Wirewrap – 100 Ω/133Ω
BT43 – 75 Ω

Chapter 1 Overview of the TimeProvider
Retimer Modules
40 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008
Each Output module plugs into a slot labeled A through D on the main shelf and on
the Expansion Panel and provides connectors and terminations for eight outputs.
Make the output connections using the procedures described in Making Output
Connections, on page 66. You can install the TIA/EIA B-422 Output module in any
of the four groups on the Main shelf only. You provision the output signal type for
each Output module using the software commands described in Provisioning the
Outputs, on page 118.
Retimer Modules
Symmetricom provides E1 and T1 Retimer modules for the TimeProvider. Each
module supports two full E1 or T1 circuits (signal types cannot be mixed on a single
Retimer module). The Retimer modules plug into one of the four slots for Output
modules in the main shelf. Retimer modules cannot be used in an Expansion Panel.
The TimeProvider meets system NEBS Level 3 and CE Class B requirements for all
configurations with a Retimer module.
The E1 Retimer module is only available with BNC connectors. The T1 Retimer
module is available only with wire-wrap connections.
Each Retimer module consists of two bi-directional circuits. Side 1 of the circuit
provides Reamplifying, Reshaping, and Retiming, or 3R. Side 2 of the circuit
provides Reamplifying and Reshaping only. Both Side 1 and Side 2 line interfaces
accept signals that are up to 16 dB down from DSX levels.
The TimeProvider generates an alarm when the Retimer exceeds a user-selected
slip rate. The default alarm level is NA (No Alarm), and the default slip rate is 4 slips
in a 24-hour period. A TL1 command allows you to clear the slip counter associated
with each Retimer port.
Should the TimeProvider or the Retimer module ever fail, a “cut-thru” capability
provides a relay bypass of the retiming circuit. The cut-thru feature automatically
engages under any of the following conditions:
User command – Disabling a port using TL1 commands
Retiming failure – A failure in the electronics (for example, power supply), or if the
module is physically removed from the shelf
All IOCs in the TimeProvider fail – IOC fault, physical removal, or shelf-level
power failure
When a cut-thru condition is detected, an autonomous event or alarm is generated;
the default alarm level is MN (Minor).

Chapter 1 Overview of the TimeProvider
Alarms
Alarms
The TimeProvider uses alarms to notify you when certain conditions are
deteriorating
below user-specified levels. These alarms are indicated by shelf and card status
lamps (LEDs) and by TL1 messages reported over the serial/EIA-232 or LAN
communication ports. In addition, the input panel has a connector that provides
contact closures to activate external alarms.
You can provision the alarm level for most alarms to one of the following levels:
non-reportable (NR), non-alarm event (NA), minor (MN), major (MJ), or critical (CR).
Alarms related to the inputs are special cases; you can only provision input alarms
for minor, major, or critical. To help prevent spurious or transient input alarms, a
delay timer (FLTDELAY) allows you to provision a waiting period that starts after the
alarm condition occurs; the alarm is set at the end of the period. A similar timer
(CLRDELAY) clears the alarm after the alarm condition is no longer present.
For more information on connecting alarms, see Making Alarm Connections, on
page 70. For information on provisioning alarm levels, see Provisioning the Alarm
Levels, on page 126.
Synchronization Status Messages (SSMs)
The TimeProvider supports input and output SSMs. SSMs provide a method for
providing clock quality information to any equipment that uses synchronization
inputs. Table 1-4 describes the ANSI SSM values and the traceability associated
with each value. Table 1-5 describes the ITU SSM values and the traceability
associated with each value.
Recommendation: To prevent Non-Service Affecting LOS
alarms, Symmetricom recommends that you provision unused
inputs to the Disabled state.

42 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008
The TimeProvider handles SSMs in accordance with T1X1.3 TR33, T1.101-1999,
GR-253, and GR-378.
Input SSMs
The TimeProvider extracts and decodes the SSM (if present) on the available
inputs. Using this information, the TimeProvider can automatically select the input
with the higher quality level.
You can manually provision the input quality level for those signals that do not have
SSM information or you can provision INP1 and INP2 to read the SSM on the input;
in either case the quality level of the reference input becomes the system’s quality
level, which is passed through to the outputs in the output SSM. If the IOC enters
the Free-run or Holdover mode, the system’s quality level is determined by the
CLKTYPE parameter for the local oscillator on the selected IOC module. You can
provision the CLKTYPE parameter to Type I, Type II, ST2, or ST3E.
Output SSMs
You must provision the TimeProvider’s outputs according to the type of SSM
operation you are using:
For ANSI SSM operation, set the output type to Extended SuperFrame (ESF) for
ANSI SSM operation.
For ITU SSM operation, set the output type to Channel Associated Signaling
(CAS) or Common Channel Signaling (CCS) with CRC4 framing. The SSM bit
location can be set by the user.

Chapter 1 Overview of the TimeProvider
SmartClock
These output formats automatically generate SSMs. The quality level of the
TimeProvider’s output depends on the quality level of the input signal or the quality
level of the local oscillator. During normal operation, when a qualified input is used
as the active timing reference, the TimeProvider copies the input’s quality level to all
DS1 ESF outputs and E1 CAS4 or CCS4 outputs. T1 SSM messages are mapped
to the corresponding equivalent E1 SSM message and vice versa.
If the IOC is operating in Holdover mode for any reason, the SSM quality is the
internal level of the oscillator installed in the IOC.
SmartClock
The TimeProvider uses Symmetricom’s SmartClock technology, which predicts
frequency changes due to aging of the local oscillator in the IOC; this offsets this
deterministic behavior by steering the output with a corrected deviation.
The TimeProvider begins the learning process as soon as you apply a valid external
reference source. The SmartClock technology is enabled after 24 hours of
continuous lock; the TimeProvider then issues an event message similar to this:
IOC1,EQPT,NA,SCAVAIL,NSA,04-12-14,12:13:14:\”SMARTCLOCK ALGORITHM, ENABLED\”
If you reset the IOC or if the oscillator becomes less stable (for example, due to
extreme temperature swings), the TimeProvider disables SmartClock and issues an
event message similar to this:
IOC1,EQPT,NA,SCAVAIL,NSA,04-12-17,15:16:17:\”SMARTCLOCK ALGORITHM, DISABLED\”
The TimeProvider automatically restarts SmartClock, which then begins to
determine a new aging rate for the oscillator.
BesTime
The TimeProvider uses Symmetricom’s BesTime algorithm when it is in the PRR
mode to provide enhanced GR-2830-CORE performance during bridging or
holdover situations. BesTime minimizes the effect of transients on the reference
signal on the outputs of the TimeProvider by comparing them against the system
reference to produce the most stable outputs from the TimeProvider.
The BesTime algorithm is based on Symmetricom’s patented use of multiple-input
phase-locked loops (MPLLs) to generate a correction signal for the local oscillator
(LO) in the IOC. With GPS as the primary input signal in PRR mode, the signals on
the PRS, INP1 and INP2 inputs may be enabled and used in the BesTime
ensembling algorithm to generate output signals derived from the optimum
weighting of each input.
Chapter 1 Overview of the TimeProvider
BesTime
44 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008
Two weighting algorithms - tracking and holdover - determine which of the inputs are
used as the ensembled reference. The tracking algorithm is used during normal
operation. If the GPS becomes disqualified, BesTime uses the holdover weighting
algorithm to determine what the GPS input would have been had it not been lost.
You can use the RTRV-BESTIME-STATS command to view the current weighting for
each input.
The BesTime control loops are designed so that the short-term (under 10 minutes)
stability is controlled by the LO, medium-term (10 minutes to several hours) stability
is controlled by the ensembled reference, and long-term stability and accuracy is
determined by the GPS control input.
The control loops can use either measurement data or prediction data. The inputs
are measured for phase, frequency, and drift transients. When the input to either loop
is determined to be valid, then the measured data is used to generate the correction
signal to the local oscillator. If BesTime detects a transient on the input, it switches to
the prediction data before the transient can start to affect the correction signal.
Normal Tracking
During normal GPS tracking, the GPS input provides the source of long-term
stability for all inputs to the ensembling algorithm. The ensembling improves the
medium-term stability of the output signals.
GPS Holdover
If GPS signals are lost, then all inputs to the ensembling algorithm have lost their
source of long-term traceability. BesTime substitutes the inputs with calibration

The ETSI-style shelf (990-58001-01) complies with ETSI 300-119 shelf projections.
Each shelf accepts one IMC or IMC/TPIU and one or two IOCs; the shelf also
supports one Input module and from one to four Output modules. Each Output
module terminates eight output timing signals. Alarms terminate on wire-wrap or
DB-25 connectors, depending on the Input module used. The minimum
configuration is one IMC or IMC/TPIU and one IOC for non-protected operation.
Using two IOC modules provides protection in case one of the IOC modules fail.
See Table 2-5 for part numbers for front-access shelf systems.

Making GPS Connections
To connect a GPS signal to the TimeProvider, you must install a GPS antenna with
either the standalone TimeProvider Interface Unit (TPIU) and an IMC or the
integrated IMC/TPIU card using the procedures in this section.
Installing the GPS Antenna
These installation procedures are to be used in support of local company
procedures and the Installation Job Specification.
Prior to installing the antenna, you should plan the site, antenna location, lightning
suppressor location, cable route, and all other details. Use Figure 3-19 as a guide to
locating the antenna.
Figure 3-19. Locating the GPS Antenna
To install the antenna, refer to Figure 3-20, and perform the procedure in this
section. Ensure all user-supplied materials are available. The maximum distance
between the antenna and the shelf is 1000 feet (304 m).

Warning: To prevent arcing, ensure that the lightning suppressor is
installed away from electrical devices and cabling.
Warning: To prevent possible damage to the TimeProvider, use only
the lightning suppressor supplied with the antenna kit.
Note: Use the following antenna installation instructions as a
guideline only. Install the antenna using company-approved
techniques, and follow all appropriate local building and electrical
codes.
Note: To achieve optimum results, the TimeProvider GPS rooftop
antenna requires a minimum cable length of 8 meters (27 feet) from
the antenna to the TimeProvider system; this overall length includes
the cable section to the lightning suppressor.
Recommendation: Symmetricom recommends that you use one of
the following grounding points:
Valid roof ring ground system.
Cad weld to building structural steel.
Central office ground plate within 15 m of antenna cable entrance
into building.
Order two cables, or a single cable run can be made from the antenna
to the TimeProvider shelf. The cable can then be cut at the lightning
suppressor location, and TNC connectors attached to the cut ends of
the cable. The “xx” in the part number indicates the cable length.

Reference Guide describes command lines and responses. For a complete
description of the TL1 syntax, refer to Telcordia (Bellcore) Technical Reference
TR-NWT-00831 and TR-NWT-00833.
TL1 Command Structure
The TL1 commands you issue to the TimeProvider use the following structure:
verb-modifier:|tid|:|aid|:[<ctag>]::|<keyword>|=<value||;
where:
: (colon) is a block separator
, (comma) is a parameter field separator
; (semicolon) is the terminating character for commands and responses
[ ] (square brackets) indicate optional parameters
Adjacent colons indicate unused fields. If an unused field is the last parameter in the
list, for example the general block or the parameter block, you can omit the colon
and simply type the semicolon.
If you enter a space in the command string, the TimeProvider ignores it.
TL1 commands are not case-sensitive.

The time and date is in the Telcordia GR-833 format. A sample normal response is:
TIMEPROVIDER 03-08-28 11:23:54
M 1 COMPLD
;
In-Process Response
The TimeProvider sends an in-process response only if it cannot respond to the
command within two seconds. The response terminates with a less-than character
(<) with no semicolon until after the TimeProvider sends the requested output
response message. The format of the in-process message is:
<cr><lf><lf>

The TL1 command may generate an event message specific to the command. This
event message accompanies the command description in this chapter.
Autonomous Messages
In addition to the TL1 response messages described in the above sections, the
TimeProvider returns Autonomous Messages to report alarms, configuration
changes, or condition changes. Frequently, an Autonomous Message is returned at
approximately the same time as the TL1 response message that is associated with
a command, because the command happens to change the unit’s state.
Autonomous Messages are not directly correlated with commands, and therefore
they do not contain a correlation tag (ctag).
The TimeProvider can generate an Autonomous Message at any time, whether to
report that a user-initiated change has occurred, to report that an active alarm
condition exists, or to report that an alarm has been cleared. The format of the
Autonomous message is as follows; note that the text REPT identifies the response
as a Autonomous Message.

Defining the Security Parameters
The TimeProvider supports users at the following four access levels:
None – Anyone with access to a serial or Ethernet port on the TimeProvider can
issue commands set to this access level. If no Security-level users are defined,
then anyone connected to the TimeProvider can issue every command available
<ipaddr> Value Description
IP address of host to be pinged 1.0.0.1 – 254.254.254.254 Pings the host system
097-58001-02 Revision G – April 2008 TimeProvider User’s Guide 95
Chapter 4 Provisioning the TimeProvider
Defining the Security Parameters
User – Users entered into the user list at the User level can issue commands set
at the User access level
Admin – Users entered into the user list at the Admin level can issue commands
set at the Admin access level
Security – Users at this access level can issue every command available
You can edit the commands available at each access level using the ED-CMD-
SECU command. You can display the current access level for each command by
issuing the RTRV-CMD-SECU command. See the TimeProvider TL1 Reference
Guide for details on these commands. Record the values you provision in Table 4-4.
The first person to log into the TimeProvider is automatically assigned the Security
access level (described in Defining a User at the Security Access Level, on page
95); this person normally performs the initial provisioning and defines users and
their appropriate access levels.
Defining a User at the Security Access Level
TimeProvider Access Levels
The security measures built into the TimeProvider are based on a list of users
authorized to access the unit. Each user has their own password and is assigned to
one of the following access levels: NONE, USER, ADMIN, or SECURITY. Users can
issue the TL1 commands available at their access level. Managing the User List, on
page 96, describes how to manage the user list.
If you do not define a Security-level user, the security features are not enabled and
an unauthorized user could gain access to the TimeProvider and compromise the
security of your network.
If you define a user at a level other than Security before you define a Security-level
user, you cannot execute Security-level commands. You will need to contact
Symmetricom Global Services (see Obtaining Technical Assistance, on page 187)
to correct this problem.
Recommendation: To avoid a possible service call to unlock the
TimeProvider, Symmetricom recommends that you enable the
security feature by defining a user at the Security access level.
Note: The factory default security setting is None, which allows all
users to access the system.
Recommendation: Symmetricom recommends that you record
and store the Security-level user’s name and password in a
secure location.

Provisioning the IOC
Provisioning the IOC
This section describes how to provision the IOC.
Setting the System Mode
The SET-SYS-MODE command allows you to provision the operating mode of the
TimeProvider to one of the following:
SSU – Synchronization Supply Unit: provides filtering compliant with G.812 and
GR-1244
SUB – Subtending mode: provides composite clock input tracking compliant with
GR-378
PRR – Primary Reference Receiver mode: provides ITU-T G.811 and Telcordia
GR-2830 requirements for Primary Reference Receivers/Clocks
In the SSU mode, you can select the system reference from signals on the GPS,
PRS, INP1, or INP2 connectors.
In the SUB mode, the PRS input is set to Monitor only; you can select the system
reference from signals on the INP1 or INP2 connectors. You can provision these
inputs to Composite Clock signal types only when the TimeProvider is in SUB mode.
In the PRR mode, the antenna provides GPS signals as the primary reference.
When enabled and qualified, the PRS, INP1, and INP2 signals are used as part of
the BesTime algorithm only to enhance the stability of the output signals. If the GPS
input is lost when in PRR mode, the TimeProvider enters the Holdover mode even if
qualified signals are present on the other inputs.
Setting the System Mode
Use the SET-SYS-MODE command to provision the TimeProvider’s operating
mode. See Operating Modes, on page 23, for more information on how the
operating mode affects the TimeProvider’s inputs and outputs.
SET-SYS-MODE:[<tid>]::[<ctag>]::<keyword>=<value>;

Controlling Automatic Reference Switching
The TimeProvider can determine which input reference signal has the highest
quality. When the active reference signal falls below a preset quality level, the
TimeProvider can automatically switch to the next highest input reference signal. To
use this feature, you must enable Automatic switching.
You can also use the performance monitoring features to automatically switch the
input reference signal when user-defined performance thresholds are crossed. See
Setting MTIE and FFOFF Thresholds, on page 116 for more information on setting
and using performance monitoring commands.
Automatic Return to a Higher Priority Reference
When the REFMODE parameter is provisioned to AUTO, the system reference
switches when the input signal is disqualified. When the input signal is re-qualified,
the TimeProvider can either keep the current reference or switch back to the
re-qualified signal. The first case, keeping the current reference, is also known as
“non-revertive” mode; the second case, switching back to the re-qualified input, is
known as revertive mode.
The QLEVEL (see Setting the Input Quality Level, on page 112) and the PRIORITY
(see Setting the Input Priority Level, on page 113) parameters work together with
SSMs to determine the switching strategy for the inputs when the unit is in the SSU
mode. If the active/primary input becomes unavailable, the switching strategy
determines which input to use: the TimeProvider uses the input with the next
highest QLEVEL. If all inputs have the same QLEVEL, then the TimeProvider uses
the input with the highest PRIORITY.
To provision the TimeProvider as non-revertive, you must provision the
user-assigned Priority Level on all inputs to the same value (1, 2, 3, or 4). To
provision the TimeProvider as revertive, you provision any one of the inputs to a
higher or lower Priority Level, with 1 being the highest priority.

Provisioning the Input Reference
112 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008
If the original primary input becomes available again, the REFMODE, QLEVEL and
PRIORITY parameters determine whether the TimeProvider switches back to that
input. If the QLEVEL and/or PRIORITY parameter of the original input is higher than
the current input, the TimeProvider reverts back to the original input. If the QLEVEL
parameter is the same for all inputs, then the TimeProvider does not revert back to
the original input.
Enabling Automatic Switching
Use the ED-SYNC command to set the reference selection to Automatic or Forced.
When set to Automatic, then the QLEVEL and PRIORITY parameters determine the
switching strategy to be revertive or non-revertive. When set to Forced, then the
TimeProvider uses the input selected with the INPREF keyword (see Manually
Selecting the Reference, on page 114).

Setting the Input Quality Level
Use the ED-SYNC command to set the quality level (QLEVEL) of the specified
input. You set the QLEVEL when using inputs that do not have an associated SSM,
or when you want to set an alarm threshold for inputs that have SSMs. The
QLEVEL determines the TimeProvider’s output SSM.
If you provision QLEVEL below the quality level of the local oscillator in the IOC,
then the TimeProvider disqualifies the input with the INPQL alarm. An INPQL alarm
also occurs if the incoming SSM indicates that the input signal is below the quality
level of the local oscillator or if the incoming SSM is below the provisioned level.
Normally, you provision the QLEVEL for each input to be either unique or all the
same. If you set all QLEVEL for inputs to unique values, then you have set up a
revertive switching strategy. If you set all inputs to the same value, then you have
set up a non-revertive switching strategy.

Enabling NTP Authentication
You use the ED-EQPT command to enable or disable MD5 authentication for NTP.
When you enable authentication, the TimeProvider as the NTP server includes the
authentication value in an encrypted portion of the time transmission (you use the
KEYGEN keyword to set the authentication key). An NTP client that has the same
authentication key value can then authenticate the identity of the NTP server.
Authentication is optional.

130 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008
Sample Command
SET-ATTR::SYS:TS1000::ELEVTIME=ENABLE;
This command allows alarms to automatically escalate to the next higher alarm
level after the time period specified in the FLTDELAY keyword has elapsed (see
Provisioning System-Level Alarms, on page 130, for more details).
Sample Command
SET-ATTR::SYS:TS1000::EXPFAIL=NA;
This command disables the Expansion Fail alarm that occurs if you are not using an
Expansion Panel with the TimeProvider.
Provisioning System-Level Alarms
You use the ED-SYNC command to provision system-level alarms. The CLRDELAY
and FLTDELAY parameters are system-wide; the parameters cannot be set for
individual alarms.
ED-SYNC:[<tid>]:<aid>:[<ctag>]::<keyword>=<value>;
This command has a default access level of ADMIN.
Note:
1When the fault is detected, the input is immediately removed from the possible reference
list. The fault must be continuously present for the period specified by FLTDELAY before
the alarm is set. After the alarm is set, it clears once the input signal is fault-free for the
period specified by CLRDELAY.
2Once INPFREQ is set, the alarm clears when the input frequency is within the defined
pull-in range

Testing Alarm Conditions
Testing the IOC Operating Modes
Warm-up Mode
The IOC enters and remains in the Warm-up mode for approximately 30 minutes
after you apply power to the shelf, or when you install the IOC into the shelf. The
following actions occur when an IOC enters the Warm-up mode:
The Power LED on the IOC flashes green
An event is generated and stored in the event log
To verify that an IOC is in warm-up mode:
1. Apply an appropriate signal to the INP1, INP2, and/or PRS inputs.
2. Visually inspect the Power LED on the appropriate IOC. The LED is flashing
green in the Warm-up mode.
3. Type RTRV-ALM::IOC1; (or RTRV-ALM::IOC2;). The TimeProvider responds
with a complied message indicating that the designated IOC is in alarm.
Locked Mode
The IOC enters and remains in the locked mode after it has completed the warm-up
cycle. The following actions occur when an IOC enters the Locked mode:
The Power LED on the IOC is green
An event is generated and stored in the event log
To verify that an IOC is in locked mode:
1. Visually inspect the Power LED on the appropriate IOC. The LED is continually
green when the IOC is tracking at least one input.
2. Type RTRV-LOG::IOC1:::EVT; (or RTRV-LOG::IOC2:::EVT;). The
TimeProvider responds with a list of events related to the specified IOC. Look for
the entry with the text “Clock entered lock mode.”

Chapter 5 Testing the TimeProvider
Testing Alarm Conditions
Testing the Reference Switching
To test the ability of the TimeProvider to switch references, you perform a two-step
test:
Connect appropriate reference inputs to the TimeProvider.
Create a fault on the selected reference signal and observe that the
TimeProvider changes to the appropriate secondary input.
To test the reference switching:
1. Connect a suitable reference signal to the PRS input and a second reference
signal to the INP1 input. Wait for the Qualified LEDs for both inputs to turn green
and for the Active LED to light on the PRS input.
2. Issue the ED-EQPT::PRS:::INSTATE=DISABLE; command to disable the PRS
input and force the TimeProvider to switch to the INP1 reference.
3. Observe that the Active LED changes from the original input to the secondary
input (PRS to INP1 or INP1 to PRS).
Testing the Non-Revertive Operating Mode
When the TimeProvider is in the non-revertive operating mode, the input reference
signal does not revert to the original input after it recovers from an error condition.
The TimeProvider is in non-revertive mode when the QLEVEL parameter for INP1,
INP2, and PRS inputs is set to the same value, and the PRIORITY parameters for
the same inputs are set to the same level.
To test the non-revertive operating mode, perform the following steps:
1. Define the non-revertive mode by setting the QLEVEL and PRIORITY
parameters to appropriate values. See Setting the Input Quality Level, on page
112, and Setting the Input Priority Level, on page 113, for further information.
2. Provision and connect appropriate reference inputs to the TimeProvider.
3. Create a fault on the selected reference signal and observe that the
TimeProvider changes to the appropriate secondary input.
4. Remove the fault on the initial reference signal and observe that the
TimeProvider does not revert to that initial reference input. The event log
indicates that the reference signal is no longer in fault.
Chapter 5 Testing the TimeProvider
Testing Alarm Conditions
150 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008
Testing the Revertive Operating Mode
When the TimeProvider is in the revertive operating mode, the input reference
signal reverts to the original input after it recovers from an error condition.
The TimeProvider is in the revertive mode when the QLEVEL parameter for INP1,
INP2, and PRS inputs are set to different values, and the PRIORITY parameters for
the same inputs are also set to different values.
To test the revertive operating mode, perform the following steps:
1. Define the revertive mode by setting the QLEVEL and PRIORITY parameters to
appropriate values. See Setting the Input Quality Level, on page 112, and Setting
the Input Priority Level, on page 113, for further information.
2. Provision and connect appropriate reference inputs to the TimeProvider.
3. Create a fault on the selected reference signal and observe that the
TimeProvider changes to the appropriate secondary input.
4. Remove the fault on the initial reference signal and observe that the
TimeProvider reverts to the initial reference input. The event log and the LEDs
indicate that the input is no longer in fault, and that the reference has changed.
Testing the Power Alarms
To test the ability of the TimeProvider to detect and report problems with the battery
power, you perform a two-step test:
Connect power to the TimeProvider on both Batt A and Batt B terminals
Remove power from one terminal and observe that the TimeProvider issues the
appropriate alarm
When power is lost from the Batt A or Batt B terminal, the factory default alarm is
Major.
1. Connect the appropriate power supply to both the Batt A and Batt B connectors.
The TimeProvider enters the Warm-up mode.
2. Remove power from either the Batt A or Batt B terminal. Observe that the Major
LED on the IMC is red. Verify that a Major alarm is included in the event log.
097-58001-02 Revision G – April 2008 TimeProvider User’s Guide 151
Chapter 5 Testing the TimeProvider
Testing the Communication Ports
Detecting Input Errors
You can provision the TimeProvider to perform a variety of functions when an input
error occurs. Possible errors include:
AIS - Alarm Indication Signal
LOS - Loss of Signal
OOF - Out of Frame
Loss of Alignment
Excessive wander
Input is disqualified
GPS faults
The TimeProvider reports these and other errors on the front panel alarm LEDs, in
an autonomous event message, and via devices connected to the alarm relays. You
can provision each error to a specific alarm level (Minor, Major, or Critical).
Setting an Alarm Strategy
You can set up the input alarms to prevent spurious input errors from triggering an
alarm. The FLTDELAY keyword parameter sets a period from 1 to 15 seconds that
an input error must be present before the alarm is issued. You can provision the
alarm to clear from 1 to 1000 seconds after the input error clears using the
CLRDELAY keyword parameter. Use the ED-SYNC command syntax described in
Provisioning System-Level Alarms, on page 130 to provision the FLTDELAY and
CLRDELAY keywords.
Testing the Communication Ports
The TimeProvider has three communication ports. This section describes how to test
each port; if you do not plan to use a port, then you can skip the corresponding test.
Local Craft serial port
Remote serial port
Ethernet port
Testing the Local Craft Serial Port
The local Craft serial port is on the faceplate of the IMC or IMC/TPIU, and is
configured as a DCE device. The default settings for the local Craft serial port are
9600 Baud, 8 bits, no parity, 1 stop bit, echo on, and handshaking disabled.
To connect a device to the local Craft port, perform the following steps:
Chapter 5 Testing the TimeProvider

If you receive a COMPAT alarm, then one or more of the installed hardware and/or
software components is not compatible with other components. Refer to the
Software Release Notice (097-58001-22) for a list of compatible components and
firmware revision levels. If necessary, update the firmware in one or more
components using the procedures in Upgrading the Firmware, on page 187.
Removing the IOC
You can remove either of two IOCs in a shelf without affecting outputs. If you need
to remove the only IOC in a shelf, or remove both IOCs from a shelf, outputs are
interrupted and will resume once one IOC has achieved lock on an input signal.
IOC Memory
The IOC stores its configuration and the configuration of the redundant IOC, if it is
installed. This configuration information is stored in non-volatile memory, and is
retained even if the IOC is removed from the shelf. The IOC also stores the
configuration of the IMC. The configuration of the IMC is stored in volatile memory
and is lost if the IOC is removed from the shelf.
Removing the Only IOC
To remove the only IOC in a shelf, use the following procedure. Output signals will
be interrupted; they will resume once the IOC has achieved lock on an input signal.
1.
Save the contents of the IOC memory in the IMC by issuing the following command
:
CPY-MEM:::::IOC,IMC,IOC;
This command may take more than two seconds to execute; if it does, then the
In-Process response is issued. See the TimeProvider TL1 Reference Guide for
more information on the CPY-MEM command.
2. Issue the following command to take the IOC out of service:
ED-EQPT::IOCm:::IOCSTATE=OOSRV;
where m is 1 or 2, and determines which IOC you take out of service.
3. Attach a wrist grounding strap and connect it to the TimeProvider chassis.

4. Loosen the captive retaining screws and pull out on them to unseat the IOC from
the shelf.
5. Place the IOC in a static-free bag or on a static-free surface.
6. Install a new IOC using the appropriate procedure in Replacing the IOC, on page
160.
Removing a Redundant IOC
To remove one IOC when two IOCs are in a shelf, use the following procedure.
1. Issue the following command to take the IOC out of service:
ED-EQPT::IOCm:::IOCSTATE=OOSRV;
where m is 1 or 2, and depends on the slot in which the IOC is installed (1 is the
left slot and 2 is the right slot).
An IOC that is out of service cannot be selected to generate or monitor outputs.
An out-of-service IOC does not generate alarms.
2. Attach a wrist grounding strap and connect it to the TimeProvider chassis.
3. Loosen the captive retaining screws and pull out on them to unseat the IOC from
the shelf.
4. Place the IOC in a static-free bag or on a static-free surface.
5. Install a new IOC using the appropriate procedure in Replacing the IOC, on page
160.
Warning: To avoid possible electrostatic damage to the IOC,
place it in a static-free bag or on a static-free surface.
Note: To avoid generating unnecessary alarms, be sure to take
the IOC out of service before removing it.
Caution: To avoid a loss of output signals, do not take the only
IOC in a shelf out of service.
Warning: To avoid possible electrostatic damage to the IOC,
place it in a static-free bag or on a static-free surface.

Removing Two IOCs
To remove both IOCs in a shelf, use the following procedure.
1. Save the contents of the Active IOC memory in the IMC by issuing the following
command.
CPY-MEM:::::IOC,IMC,IOC;
This command may take more than two seconds to execute; if it does, then the
In-Process response is issued. See the TimeProvider TL1 Reference Guide for
more information on the CPY-MEM command.
2. Issue the following TL1 command to take the Standby IOC out of service:
ED-EQPT::IOCm:::IOCSTATE=OOSRV;
where m is 1 or 2, and corresponds to the location of the Standby IOC (1 is the
left slot and 2 is the right slot).
3. Attach a wrist grounding strap and connect it to the TimeProvider chassis.
4. Loosen the captive retaining screws and pull out on them to unseat the IOC from
the shelf.
5. Place the IOC in a static-free bag or on a static-free surface.

Diagnosing the Retimer Module
The Retimer module is transparent to framing errors, bipolar violations, and data
errors; these errors are passed through to the downstream Network Element. If an
incorrect signal type is inserted into the Retimer module (for example, if an E1
signal is connected into a T1 Retimer), the module may report a large slip count.
Verify that the proper signal is inserted into the Retimer module.
Note: If the replacement IMC has a different software load than the
original IMC, you cannot log in to the TimeProvider using the existing
username and password. You must create a new username and
password using the ENT-USER-SECU command.

Repairing the TimeProvider
Repairing the TimeProvider is limited to replacing cards. Refer to Working With
Cards, on page 82, for information on how to properly handle cards and modules to
prevent electrostatic or physical damage.
To remove an IOC, loosen the captive screws and lift the removal tabs on each side
of the card, then slide the module out of the shelf. To remove the IMC, loosen the
captive screws and pull the module out of the shelf using the U-shaped handle on
the front panel. Place the module on an anti-static surface or in an anti-static bag.
To remove an Input or Output module, loosen the captive screws and then pull the
module using the captive screw. Place the module on an anti-static surface or in an
anti-static bag.
Obtaining Technical Assistance
If you have technical questions about the TimeProvider, call Symmetricom Global
Services (SGS) at 888-367-7966 (toll-free in USA only), 408-428-7907, or
+49 700 3288 6435 in Europe, Middle East, or Africa. You can also email your
technical questions to support@symmetricom.com or
emeasupport@symmetricom.com.
Upgrading the Firmware
You can upgrade the firmware in the IMC or IOC using TL1 commands and software
available from Symmetricom. Only users with Admin-level or Security-level access
can execute the command. The command places the management module in the
firmware download mode and terminates all sessions except the session performing
the upgrade. During the upgrade process, no new sessions are allowed. Refer to
the TL1 Reference Guide for details on the upgrade process.
Use the following TL1 command to download the firmware.
Warning: To avoid possible electrostatic damage to the module
or panel, place it in a static-free bag or on a static-free surface.
Caution: To avoid a possible service call, do not issue any additional
TL1 commands to the TimeProvider, do not remove power from the
TimeProvider, and do not remove an IOC or IMC from the shelf during
the firmware upgrade process (minimum 30 minutes). Doing so could
corrupt the flash memory in a card, disabling the TimeProvider.

Upgrading the Firmware
188 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008
ACT-SWDL:[<tid>]:<aid>:[<ctag>];
After you issue the command, you have 60 seconds to begin transferring the
upgrade file using the Ymodem transfer protocol. If you do not start the transfer
within 60 seconds, the command times out and you will have to issue the ACT-SWDL
command again. You can use the SynCraft application to transfer the upgrade file;
be sure to follow the recommendations in the Caution, above.
The system downloads the firmware using the Ymodem protocol; if the IMC
firmware is upgraded, the processor in the IMC is reset.
Sample Command
ACT-SWDL::IMC:TP1000;
If the image transfer takes more than 60 seconds to start, the error response is
SROF and the IMC returns to normal operation. You will need to start the download
process again to perform the upgrade.
If the header information in the referenced file is not correct, the error response is
SROF, followed by a message that says the firmware upgrade was not successful.
If the file header is correct, the TimeProvider responds with a message stating that it
is beginning the firmware upgrade, followed by a message stating the upgrade was
successful.
<aid> Description
IMC Downloads a new firmware image to the IMC.
If the IMC or IOC provisioning has changed in the newly upgraded firmware, you may
need to issue the CPY-MEM command from an in-service IOC to the IMC before the
IMC is fully functional. See the TimeProvider TL1 Reference Guide for more details.
IOC Downloads a new firmware image to the IOC.
Symmetricom recommends that redundant IOCs use the same firmware revision.
The Active IOC enters Standby mode, putting the second IOC in Active mode. After
acknowledging the changeover, the IMC starts the firmware transfer to the Standby IOC.
After the download, the Standby IOC must achieve Lock (CLKLOCK) mode before
changing again to Active mode. The Standby IOC is then upgraded.
If the first IOC upgrade is not successful, the entire process is aborted and an SROF
error message is generated. The IOC restarts with the existing firmware.
IOCm
m = 1 | 2 Downloads the IOC firmware image from the Active IOC to the Standby IOC.
This command does not require Ymodem or SynCraft to transfer an image file from
the computer to the TimeProvider.
097-58001-02 Revision G – April 2008 TimeProvider User’s Guide 189
Chapter 6 Maintaining and Troubleshooting the TimeProvider
Upgrading the Firmware
Upgrading the IMC
To upgrade the software in the IMC, use the following procedure. You must have the
upgrade software available on diskette or other media, as well as a Ymodem
file-transfer program such as SynCraft available before you begin the procedure.
Outputs are not affected during the IMC upgrade procedure.
1. Log in to the TimeProvider with an Admin- or Security-level user id and
password.
2. Back up the contents of the IMC memory in an IOC by issuing the following
command:
CPY-MEM:::::IMC,IOC,IMC;
3. To start the download, issue the command
ACT-SWDL::IMC:TP1000;
The TimeProvider issues an In-Process response, the TL1 connection closes,
and the TimeProvider waits to receive the upgrade software using the Ymodem
protocol.
4. Use a Ymodem file transfer program such as SynCraft to transfer the upgrade
software to the TimeProvider. You must start the transfer within 60 seconds or the
TimeProvider issues a Deny response.
The TimeProvider validates the received file, updates the flash memory and
reboots the IMC if the file is valid. If the file is not valid, the TimeProvider issues a
Deny response.
5. The COMPLD message appears after a successful transfer.
Upgrading the IOC
This section contains procedures for upgrading a shelf with a single IOC and for
upgrading a shelf with redundant IOCs.
Upgrading Single IOCs
To upgrade the software in a single IOC, use the procedure in this section. Outputs
from the TimeProvider will be interrupted for up to 30 minutes until the upgraded
IOC enters the Locked mode.
1. Log in to the TimeProvider with an Admin- or Security-level user id and
password.
2. Save the contents of the IOC memory in the IMC by issuing the command:
CPY-MEM:::::IOC,IMC,IOC;
Chapter 6 Maintaining and Troubleshooting the TimeProvider
Upgrading the Firmware
190 TimeProvider User’s Guide 097-58001-02 Revision G – April 2008
3. To start the download, issue the command
ACT-SWDL::IMC:TP1000;
The TimeProvider issues an In-Process response, the TL1 connection closes,
and the TimeProvider waits to receive the upgrade software using the Ymodem
protocol.
4. Use a Ymodem file transfer program such as SynCraft to transfer the upgrade
software to the TimeProvider. You must start the transfer within 60 seconds or the
TimeProvider issues a Deny response. The new software is loaded into the IOC,
after which it is rebooted and enters the Warm-up mode for up to 30 minutes.
5. The COMPLD message appears after a successful transfer.
6. Restore the contents of the IOC memory from the IMC by issuing the command:
CPY-MEM:::::IMC,IOC,IOC;
Upgrading Redundant IOCs
To avoid output interruptions, the TimeProvider must be in the following state:
Two installed and communicating IOCs
Both IOCs are in the Locked mode
Both IOCs are In Service
Both IOCs are alarm-free
One IOC is Active
If any of these conditions are not present, then the outputs are interrupted for up to
30 minutes until the upgraded IOC enters the Locked mode.
To upgrade the software in both IOCs, use the following procedure:
1. Log in to the TimeProvider with an Admin- or Security-level user id and
password.
2. Back up the contents of the IOC memory in the IMC by issuing the command:
CPY-MEM:::::IOC,IMC,IOC;
3. Start the download by issuing the command:
ACT-SWDL::IMC;
The TimeProvider issues an In-Process response, the TL1 connection closes,
and the TimeProvider waits to receive the upgrade software using the Ymodem
protocol.

Chapter 6 Maintaining and Troubleshooting the TimeProvider
Returning the TimeProvider
4. Use a Ymodem file transfer program such as SynCraft to transfer the upgrade
software to the TimeProvider. You must start the transfer within 60 seconds or the
TimeProvider issues a Deny response.
The active IOC (IOC1 for example) goes into Standby mode and the Standby
IOC (IOC2, in this example) goes into Active mode. The new software is loaded
into IOC1, after which it is rebooted and enters the Warm-up mode for up to 30
minutes.
When IOC1 enters the Locked mode, it becomes the Active IOC again (IOC2
goes into Standby). The new software is loaded into IOC2, after which it is
rebooted and enters the Warm-up mode for up to 30 minutes.
5. The COMPLD message appears after a successful transfer.
Upgrading One IOC From the Other
To upgrade the software in one IOC to match the software in the other IOC, issue
the command:
ACT-SWDL::IOCn:TP1000;
where n = 1 or 2, and identifies the IOC that receives the software from the other
IOC
You cannot upgrade the software in the Active IOC.

Clocks
LAN Port
The Ethernet 10BaseT port supports 10 full-duplex telnet sessions over TCP/IP. To
minimize response delays, Symmetricom recommends that you keep four or fewer
sessions open at any one time.
Clocks
The clocks in the TimeProvider are controlled with Direct Digital Synthesis
technology for calibration-free operation and precise frequency control.

Hold-in and Pull-in Range
Table 7-3 lists the default values for the Hold-in range and Pull-in range for the
Clock cards available for the TimeProvider.
According to GR-1244, hold-in is the process by which an NE and its clocks
maintain lock to the active reference as the frequency of that reference varies
arbitrarily slowly. Thus, the hold-in range is the largest band of input signal
frequency for which the NE and its clocks will maintain lock. As is the case for the
pull-in range, the hold-in range is generally specified so that an NE/clock of a given
stratum level will maintain lock with a reference that is traceable to a clock of the
same stratum level.
According to GR-1244, pull-in is the process during which an NE's clocks become
locked to a reference. In turn, an NE's pull-in range is the largest band of input
reference signal frequency for which its clocks will acquire lock. In general, pull-in
requirements are intended to assure that any NE/clock will always be able to lock to
a reference signal that is traceable to a clock of equal (or higher) quality. Therefore,
for a given stratum level the minimum pull-in range is generally the same as the
maximum acceptable free-run frequency offset.
Inputs
Front Access and Rear Access shelves contain three card slots: two for IOC cards
and one for an IMC or integrated IMC/TPIU card.
Each IOC supports three input ports: two span inputs and one PRS input.
Input supported:
PRS Input port: 2048 kHz G.703/13, 1.544/5/6.312/10 MHz sine or square
