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 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.

Chapter 1 Overview of the TimeProvider
Overview
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.
22 TimeProvider User’s Guide |
097-58001-02 Revision G – April 2008 |
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.
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 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.
24 TimeProvider User’s Guide |
097-58001-02 Revision G – April 2008 |
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.

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 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 |
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
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.
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 TimeProvider 1000.
