Chapter 1 Overview of the TimeProvider

Overview

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

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

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

The TimeProvider also uses Symmetricom’s BesTime

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

Shelves

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

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

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

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

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

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

Inputs

The TimeProvider accepts the following types of input signals:

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

10 MHz

 Span input signals:

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

Composite Clock with 400 Hz (JCC4) signals

 GPS input:

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

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

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

Outputs

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

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

Chapter 1 Overview of the TimeProvider

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

Operating Modes

Communication

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

Communication Ports, on page 34.

Clocks

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

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

Operating Modes

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

SSU Mode

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

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

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

Chapter 1 Overview of the TimeProvider

Performance Monitoring

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

SUB Mode

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

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

PRR Mode

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

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

990-58545-04)

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

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

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

Performance Monitoring

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

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

Chapter 1 Overview of the TimeProvider

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

For more information on performance monitoring, see Using Performance

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

section describing the TL1 commands related to performance monitoring.

Performance Monitoring

Phase Measurements

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

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

MTIE Calculations

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

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

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

TDEV Calculations

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

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

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

Chapter 1 Overview of the TimeProvider

NTP Operation

FFOFF Calculations

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

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

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

NTP Operation

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

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

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

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

 Typical unencrypted response time from the TimeProvider on an unloaded

network is < 10 ms

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

network is < 50 ms

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

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

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

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

Chapter 1 Overview of the TimeProvider

NTP Operation

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Chapter 1 Overview of the TimeProvider

SNMP – Simple Network Management Protocol

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

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

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

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

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

Physical Description

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

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.

097-58001-02 Revision G – April 2008 TimeProvider User’s Guide 31

Chapter 1 Overview of the TimeProvider

Functional Description

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 sp ace 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 co mplies 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 T imeProvide r output is the n depende nt 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 requa lified 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 T ime Provider 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;

Chapter 1 Overview of the TimeProvider

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.

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

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 AUT O, 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

097-58001-02 Revision G – April 2008 TimeProvider User’s Guide 35

Chapter 1 Overview of the TimeProvider

Reference Input Signals

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 TimeProvid er as non-revertive, you m ust 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.

Clock Performance

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.

Chapter 1 Overview of the TimeProvider

Clock Performance

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 int erchangeable 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  TIA/EIA B-422 Wirewrap – 100 Ω (installed in main shelf only)

097-58001-02 Revision G – April 2008 TimeProvider User’s Guide 39

Chapter 1 Overview of the TimeProvider

Retimer Modules

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 requirement s 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 th e

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).

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

Alarms

Chapter 1 Overview of the TimeProvider

Alarms

The TimeProvider uses alarms to notify yo u when cert ain 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 (FL TDELAY) 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.

Recommendation: To prevent Non-Service Affecting LOS alarms, Symmetricom recommends that you provision unused inputs to the Disabled state.

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.

7SMC

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 (C CS) with CRC4 framing. The SSM bit location can be set by the user.

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

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 TimeProv ider 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 yo u 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:

Chapter 1 Overview of the TimeProvider

SmartClock

IOC1,EQPT,NA,SCAVAIL,NSA,04-12-14,12:13:14:\”SMARTCLOCK ALGOR ITHM, ENABLED\”

If you reset the IOC or if the oscillator becomes less stable (for example, due to extreme temperature swings), the TimeProvider disable s 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 Ti meProvider 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.

097-58001-02 Revision G – April 2008 TimeProvider User’s Guide 43

Chapter 1 Overview of the TimeProvider

BesTime

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. Y ou can use the RT RV -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) st ability 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 inpu ts 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 BesT ime detect s 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 predictions with respect to GPS. Each input is weighted according to the estimated prediction error over 24 hours.

Chapter 2 Engineering and Ordering Procedures

Shelf

The TimeProvider is available in two configurations: Mode l 1000 Front Access and Model 1100 Rear Access.

Model 1000 Front Access

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.

Model 1100 Rear Access

The NEBS-style shelf (990-58101-01) 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.

Chapter 4 Provisioning the TimeProvider

TL1 Overview

The TimeProvider uses the TL1 syntax; this chapter and the TimeProvider TL1 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 p arameter 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.

Table 4-1 describes the syntax used in this manual.

Table 4-1. TL1 Syntax Conventions

Symbol Description

^ Space character (ASCII 0x20) <cr> Carriage return (ASCII 0x0D) <lf> Line feed (ASCII 0x0A) [ ... ] Optional command parameter or data < ... > ASCII characters sent in commands or returned in response ( ... ) Numeric data that can be positive or negative

Chapter 4 Provisioning the TimeProvider

TL1 Overview

TL1 Response Format

Normal Response

For each TL1 command described in this chapter there is a normal response, an in-process response, or an error response. The TimeProvider response is always upper-case. The format of a normal response is:

<cr><lf><lf> ^^^sid^date^time<cr><lf> M ^ctag^COMPLD<cr><lf> ;

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> ^^^sid^date^time<cr><lf> IP^ctag<cr><lf> <

A sample in-process response is:

TIMEPROVIDER 03-08-28 11:24:15 IP^2 <

Error Response

If you mis-type a command or issue an invalid command, the TimeProvider sends an error message. The format of the error response is:

<cr><lf><lf> ^^^sid^date^time<cr><lf> M ^ctag^DENY<cr><lf> ^^^<errcde><cr><lf> ;

A sample error message is shown below:

Chapter 4 Provisioning the TimeProvider

Starting the TimeProvider for the First Time

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 REP T identifies the re sponse as a Autonomous Message.

sid date time <cr><lf> almcde atag REPT reptype aidtype<cr><lf>

aid,aditype:ntfcncde,condtype,srveff,ocrdat,ocrtim:condscr ”<cr><lf> ;

Refer to the TimeProvider TL1 Reference Guide for more information on Autonomous Messages.

Starting the TimeProvider for the First Time

The TimeProvider is delivered with a copy of SynCraft, Symmetricom’s network management application. Before you can use SynCraft or other network management software, you must provision the following parameters, as described in this section and in Setting Communications Parameters, on page 91:

 Source ID (sid)  Date and time  Ethernet parameters  Security-level user

Defining the Security Parameters

Checking Communication Links

Two commands allow you to check the communication links from a computer or network to the TimeProvider: PING and RTRV-HDR.

Ping

Use the PING command to check an Ethernet connection to the TimeProvider.

PING:[<tid>]::[<ctag>]::<ipaddr>;

This command has a default access level of USER.

<ipaddr> Value Description

IP address of host to be pinged 1.0.0.1 – 254.254.254.254 Pings the host system

Sample Command

PING:::TS1000::192.168.12.10;

Normal Response

TP-SSU 03-05-15 09:59:09 M TS1000 COMPLD “Host 192.168.12.10 is alive. Roundtrip time was 165 ms” ;

Retrieve Header

Use the RTRV-HDR command to display the response header, which includes the system identification <sid>, date, and time. You can also use this command to verify that the communication link to the TimeProvider is working properly.

This command has a default access level of NONE.

Sample Command

RTRV-HDR:::TS1000;

Normal Response

TP-SSU 03-05-15 09:59:25 M TS1000 COMPLD ;

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

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

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-CMDSECU 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

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.

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.

Note: The factory default security setting is None, which allows all users to access the system.

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: Symmetricom recommends that you record and store the Security-level user’s name and password in a secure location.

Chapter 4 Provisioning the TimeProvider

Managing the User List

Adding a User at the Security Access Level

To define a user at the Security access level, issue the following TL1 command. The user and password you create is the same user and password used to access the TimeProvider using the SynCraft application (see Using SynCraft, on page 102).

Sample Command

ENT-USER-SECU::DEPTHEAD:TS1000::TP01!,SECURITY;

This sample command creates a user with the name DEPTHEAD and a password of TP01!; this user is at the Security access level. See Adding a User, on page 98, for more information on the ENT-USER-SECU command.
