2ChapterALARM INFORMATIONThis section describes the meaning, possible causes, and procedures of alarms in the LoopStar 800.

AIC What It Means The DS3 signal for monitoring Application Identification Channel (AIC) signals does not match in frame format.

Possible Causes • The frame format of the received DS3 signal differs from that set at the local end. • The frame format of the transmitted DS3 signal differs from that set at the local end.

AIS What It Means Upstream equipment detected a DSn signal failure.

Upstream equipment detects a data signal failure (Only for LPS-EFS8 and LPS-ELS4 unit).

Possible Causes • Upstream equipment detected a DSn LOS alarm or DSn LOF alarm (when the AIS upon LOF insertion function

are enabled). • •Upstream equipment is under loopback. • Upstream equipment has OCN LOS/LOF/AIS-L/LOP-P/AIS-P/UNEQ-P/PLM-P/TIM-P (when the J1 monitoring

mode is enabled) alarms.

Actions

Step Action1 Check the frame format of the DS3 signal transmitted from the client end.2 Check the frame format of the DS3 signal received from the client end.3 Check frame format settings of the DS3 port at the local end against that at the client end with TL1

command RTRV-T3.

Step Action1 Check where the AIS alarm is generated (locally or at an upstream NE) according to the alarm direction

with TL1 command RTRV-COND-ALL.2 Check the local end and upstream equipment for DSn LOS and DSn LOF alarms (when the AIS upon

LOF insertion function are enabled) with TL1 command RTRV-COND-ALL.3 Check the local end and upstream equipment for whether they are under loopback, TACC or bit

sequence test with TL1 command RTRV-LPBK-<OCN/T1/T3/STS_PATH>.4 Check the local end and upstream equipment for OCN LOS/LOF/AIS-L/LOP-P/AIS-P/UNEQ-P/PLM-P

alarms and TIM-P (when the J1 monitoring mode is enabled) alarm with TL1 command RTRV-COND-ALL.

Chapter 2: Alarm Information

2-2 LPS800-UM-PERF-04

AIS-L What It Means Line alarm indication signals.

Possible Causes The LoopStar 800 detects an AIS in the SONET overhead. The bits 6, 7 and 8 of the K2 byte contain the "111" pattern in five consecutive frames.

This alarm is secondary to LOS or LOF alarm occurring simultaneously in an upstream node. A service path generates AIS-L downstream within 125 µs of detecting an LOS or LOF defect on the incoming signal. For example, it is raised when the port on the reporting node is in service but an upstream node on the circuit does not have its OC-N port in service. The upstream node often reports an LOS or has an OC-N port not in service. The AIS-L clears when you clear the primary alarm on the upstream node. An AIS-L occurs at the line layer.

Actions

AIS-P What It Means Path alarm indication signal.

Possible Causes The LoopStar 800 detects an AIS in the SONET overhead. The H1 and H2 bytes for an STS path contain an all-ones pattern in three consecutive frames.

This alarm is secondary to LOS, LOF or LOP alarm occurring simultaneously in an upstream node. A service path generates AIS-P within 125µs of terminating the defect that caused it to be sent, or in the case of a local equipment failure, within 125µs of clearing the failure or determining that standby equipment has been switched in.

The AIS is caused by an incomplete circuit path including the failures with components (i.e., optical interface and fiber). For example, it is raised when the port on the reporting node is in service, but a node upstream on the circuit does not have its port in service. The upstream node often reports a LOS or has an OC-N port not in service. The AIS-P clears when the primary alarm on the upstream node is cleared.

AIS-P occurs in each node on the incoming OC-N path. The Path layer deals with the transport of various payloads between SONET terminal multiplexing equipment.

Actions

Step Action1 Check upstream nodes and equipment for alarms, especially for the LOS and the out-of-service port with

TL1 command RTRV-COND-ALL.2 If these alarms exist at upstream nodes, perform the corresponding steps to clear them.

Step Action1 Check upstream nodes and equipment for alarms, especially the LOS and the out-of-service ports with

TL1 command RTRV-COND-ALL.2 If these alarms exist at the upstream nodes, perform the corresponding steps to clear them.

LPS800-UM-PERF-04 2-3

AIS-V What It Means Virtual tributary layer alarm indication signal.

Possible Causes • Service is configured incorrectly. • Caused by higher-order alarms (i.e., AIS-L/LOP-P/UNEQ-P/PLM-P/TIM-P).

The LoopStar 800 detects an AIS in the SONET overhead. This alarm is secondary to LOS, LOF, LOP or UNEQ alarm occurring simultaneously in an upstream node. An incomplete circuit path causes an AIS. For example, it is raised when the port on the reporting node is in service but a node upstream on the circuit does not have its OC-N port in service. The upstream node often reports a LOS or has an OC-N port not in service. The AIS-V clears when the primary alarm is cleared. The node with the port not in service may not report any alarms to indicate it is at fault.

An AIS-V indicates that an upstream failure occurred at the VT layer which is created when the SONET signal is broken down into an electrical signal. For example, it can be raised when an optical signal comes into an LoopStar 800 OC-N unit. If the LoopStar 800 demultiplexes this optical signal, and one of the paths separated from the optical signal is then cross-connected into the XTC ports in the same node, that LoopStar 800 reports an AIS-V alarm. An AIS-V error message on the electrical unit is accompanied by an AIS-P error message on the cross connected OC-N unit.

Actions

ALS What It Means Automatically shutdown the transmit optical interface of the laser on detecting a LOS.

Possible Causes This alarm occurs when the LOS alarm is detected.

Actions

An AIS-V can be raised on the OC-N unit only when the attribute <LUVTALM> is set to Y by using the TL1 command ED-SYS.

Step Action1 Check the alarms of upstream nodes, especially LOS and out-of-service ports with TL1 command

RTRV-COND-ALL.2 If these alarms exist at the upstream nodes, perform the corresponding steps to clear them.

Step Action1 Check the status of the upstream NE and verify the laser is ON and the output signal is within

specifications with TL1 command RTRV-COND-ALL and RTRV-<OCN>.2 Verify the fibers at the upstream NE are connected correctly and free from dust or dirt. 3 Verify the fibers at the local NE are connected correctly and free from dust or dirt.4 If the above actions do not work, turn off the automatic laser shutdown function to remove the ALS alarm

with TL1 command ED-LASER-<OCN>.

APSB What It Means This alarm indicates that a protection switching failure of incoming K1 byte.

Possible Causes • There are no three identical successive frames in 12 frames. • The K1 byte contains unused bits. • The K1 byte contains bits irrelevant to the current operation. • The fiber connection between the local NE and the opposite NE is wrong.

Actions

APSCM What It Means The bits 5–8 of the transmitted K1 byte do not indicate a same path number as the bits 1–4 of the received K2 byte (1+1 single-end switching does not check this alarm).

Possible Causes • A switching occurs when the protection groups at the both ends are of different types (one is of 1+1, while the

other is of 1:N). • An end NE does not have its protocol started or its protection group created. • The fibers are not connected correctly.

Actions

APSMM What It Means The LAPS protection groups of the end NEs have different switching modes (1+1 single-end switching does not detect this alarm).

Possible Causes One end NE is of single-end switching and the other of dual-end switching.

Actions Query the switching mode of the NEs at both ends and ensure they are of the same switching mode with TL1 command RTRV-FFP-OCN.

Step Action1 Check the hardware for related alarms (EQPT-NSA or EQPT-SA). If the unit’s indicator is yellow, there is

EQPT-NSA reported. If the unit’s indicator is red, there is EQPT-SA reported. Refer to corresponding actions to clear the alarm.

2 Check the K1 byte records for illegal K1 bytes received by the local NE and transmitted from the opposite NE.

Step Action1 Check whether the NEs at both ends have their protection groups created correctly and protocols started

with TL1 command RTRV-FFP-OCN.2 Check whether the fibers are connected correctly.

Chapter 2: Alarm Information

LPS800-UM-PERF-04 2-5

APSTM What It Means The NEs at the both ends are in different types of LAPS protection groups (1+1 single switching does not check this alarm).

Actions Query the protection group types of the end NEs and ensure they are in protection groups of the same type with TL1 command RTRV-FFP-OCN.

ATE-RMV What It Means The ATE card offline or uninstalled.

Possible Causes The slot where the ATE logic unit is created does not house a physical ATE unit.

Actions

AUTOSW What It Means The Protected service switches from the working part to the protection part automatically.

Possible Causes • The working unit is damaged. • The working unit is offline. • The physical unit and the logical unit mismatch. • For the UPSR, the service switches from the working path to the protection path automatically when:

– The alarms (i.e., AIS, UNEQ-P, UNEQ-V, SD, SF) exist in the working path. – The protection path works normally or the alarm in the protection path has a lower severity level than that

in the working path.

Actions

Step Action1 Check to see if the physical unit is inserted. If not, insert the physical unit.2 Check to see if the physical unit is inserted with TL1 command RTRV-EQPT.3 If so, it has failed. Replace it with a new one.

Step Action1 When the working part returns to the normal state, the revertive protected service will switch to the

working part automatically and then the alarm is cleared. Some other switching commands (i.e., FRCD) also can clear the alarm.

2 For UPSR, query if there is any alarm in the working path with TL1 command RTRV-ALM-<MOD2>. If there are alarm(s), clear the alarms according to the corresponding steps.

BLSR-SD-R What It Means The SD ring switching occurs in BLSR.

Possible Causes • Ring switching occurs because the signal received from working path degrades. • If it is a local alarm, the local NE may detect the conditions for the SD ring switching in the corresponding BLSR

ring and then trigger the SD ring switching. • If it is a remote alarm, the opposite NE may detect the conditions for the SD ring switching in the corresponding

BLSR ring and then trigger the SD ring switching.

Actions Check whether the SD-L alarm exists at the optical interfaces corresponding to the local NE or opposite NE according to the alarm. After the conditions are cleared, the SD ring switching will be recovered.

For 4-fiber BLSR, if signal received degrades, span switching occurs first by default. But if the protection path is locked or SD/SF exists in protection path (namely span switching cannot be executed), ring switching occurs later.

Chapter 2: Alarm Information

T-UASP-P What It Means The path layer of the T3 electrical port has an SESP-P for 10 seconds or longer.

The T-SESP-P is a performance event reported when the SESP count exceeds a threshold in a performance cycle due to a P-bit, SEF or AIS at the path layer of the T3 electrical port.

Possible Causes • It is caused by the alarms of the corresponding interface or path. • The cable interface is of poor contact. • The cable is not inserted correctly. • The interface unit is not inserted correctly. • The local end receives too strong or too weak signals. • The local end cannot receive signals efficiently. • The opposite end cannot transmit signals efficiently.

Actions For the DSn receiving signal:

For the DSn transmitting signal:

Step Action1 Check whether there is any alarm of the corresponding interface or path. If there is, clear the alarm

according to the corresponding steps.2 Replace the cable with one of better quality. Connect the cable and install the interface unit correctly. Set

balanced input/output to the port.3 Check the port of the DSn unit that accesses the service. If there is any alarm, clear it according to the

corresponding steps. 4 Replace the faulty unit.5 Check the DSX panels.

Step Action1 Check whether there is any alarm of the corresponding interface or path. If there is, clear the alarm

according to the corresponding steps.2 Check the transmitting DSn signal and the OC-N unit to see whether there is B1, B2 or B3 bit errors. If so,

go to Step 3. If not, go to Step 4. Check the receiving DSn signal of opposite end to see whether there is T-UASP-P. If there is, perform the steps for the DSn receiving signal.

3 Use an adjustable attenuator to adjust the optical power and keep the fiber connector clean.4 Check the clock configuration of the entire network with TL1 command RTRV-SYNCLIST. Make sure

T-UAS-V What It Means The VT path layer of the OC-N or DS1 signal has an SES-V for 10 seconds or longer.

The T-SES-V is a performance event reported when the SES count exceeds a threshold in a performance cycle due to a V5BIP2CNT (bits 1–2 of the V5 byte), LOS, LOF, AIS-L, LOP-P, AIS-P, TIM-P, UNEQ-P, LOP-V, AIS-V or UNEQ-V at the VT path of the OC-N, DS1 or Ethernet signal.

Possible Causes • It is caused by the alarms of the corresponding interface or path. • If it is reported from an OC-N unit, it indicates the following possibilities:

– The received power of the optical port is too high or too low. – The fiber connector is too dirty.

• If it is reported from a DSn processing unit, it indicates the following possibilities: – The cable interface is of poor contact. – The cable or interface unit is not inserted correctly. – The port receives too strong or too weak signals.

• The local end cannot receive signals correctly. • The opposite end cannot transmit signals correctly. • The clock configuration of the entire network is wrong. • Alarms exist at the port of the DSn unit or the Ethernet unit that accesses the service. • The unit is faulty.

Actions

Step Action1 Check whether there is any alarm of the corresponding interface or path. If there is, clear the alarm

according to the corresponding steps.2 Check the corresponding optical interface or path of the OC-N unit to see whether there is B1, B2 or B3

bit errors. If so, go to Step 3. If not, go to Step 4.3 Use an adjustable attenuator to adjust the optical power and keep the fiber connector clean.4 Check the clock configuration of the entire network with TL1 command RTRV-SYNCLIST. Make sure

there is only one master clock.5 Replace the faulty unit.

UNEQ-P What It Means An unequipped path alarm occurs when the path does not have a valid sender.

Possible Causes The C2 byte is zero.

Actions

UNEQ-V What It Means VT path unequipped.

Possible Causes • An upstream intentional indication because of an unequipped circuit or DS1 signal failure if the option is

enabled. • Circuit configuration error.

Actions

UPGRADE-IP What It Means The OCN unit or the common control unit is being upgraded with the rate.

Possible Causes A rate upgrade of the unit is under way.

Actions Modify the rate of the unit with TL1 command ED-EQPT to finish the upgrade or roll back.

Step Action1 Check whether the service is configured correctly. If not, correct it.2 Check whether the C2 that the home station should receive and the C2 that the opposite station should

transmit are consistent. If not, make them consistent. Query the C2 byte with TL1 command RTRV-<STS_PATH> and make sure the path is in the OOS state. If not, change the value of <PST> to IS with TL1 command ED-<STS_PATH>.

3 Edit the C2 byte with TL1 command ED-<STS_PATH>.

A UNEQ-V can be raised on the OC-N unit only when the attribute <LUVTALM> is set to Y by using the TL1 command ED-SYS.

Step Action1 Check whether the service is configured correctly. If not, correct it. 2 To keep the service added/dropped is properly and completely provisioned and activated.

WKSWBK What It Means Switch protection to working unit (Performance event).

Possible Causes Traffic switch back from the protect unit to working unit automatically or manually.

WKSWPR What It Means Switch working to protection unit (Performance event).

Possible Causes Traffic switches from the working unit to protect unit automatically or manually.

WTR What It Means Wait to restore.

The path (unit) sending automatic switching is restored to normal from unavailable.

Possible Causes When a local condition that caused an automatically initiated switch clears.

XCON-MM What It Means The cross-connect type does not match adjacent nodes.

Possible Causes In a BLSR ring, if the cross-connect type of a node differs from that of the adjacent nodes, the adjacent nodes report this alarm.

Actions Change the cross-connect type of the node to the same as the other nodes.

A monitored partition comprises all bits which are in the same bit position within the X-bit sequences in the covered portion of the signal. The covered portion includes the BIP-X.

Bit Error An error occurs to some bits in the digital code stream after being received, judged, and regenerated, thus damaging the quality of the transmitted information.

Path Protection The working principle of path protection: When the system works in path protection mode, the PDH path uses the dual-fed and signal selection mode. Through the tributary unit and cross-connect unit, the tributary signal is sent simultaneously to the east and west lines. Meanwhile, the cross-connect matrix sends the signal dually sent from the opposite end to the tributary board through the active and standby buses, and the hardware of the tributary board automatically and selectively receive the signal from the two groups of buses automatically according to the AIS number of the lower order path.

Path Terminating Equipment

Network elements (i.e., fiber-optic terminating systems) which can access, generate, and process Path Overhead.

Payload The portion of the SONET signal available to carry service signals (i.e., DS1 and DS3). The contents of an STS SPE or VT SPE.

PDH Plesiochronous Digital Hierarchy. PDH is the digital networking hierarchy that was used before the advent of Sonet/SDH.

Performance Threshold

Performance events usually have upper and lower thresholds. When the performance event count value exceeds the upper threshold, a performance threshold-crossing event is generated; when the performance event count value is below the upper threshold for a period of time, the performance threshold-crossing event is ended. In this way, performance jitter caused by some sudden events can be shielded.

PIN PIN Photodiode. A semiconductor detector with an intrinsic (i) region separating the p and n-doped regions. It has fast linear response and is used in fiber-optic receivers.

Procedure A generic term for an action.

Process A generic term for a collection of actions.

Protection Path A specific path that is part of a protection group and is labeled protection.

Provisioning The process of making available various telecommunications resources (i.e., switching systems and transport facilities) for telecommunication services. Provisioning includes forecasting the demand for services, determining the additions or changes to the network that will be needed, determining where and when they will be needed, and installing all the necessary network elements to provide such services.

a failure condition has been declared downstream. (RAI signals were previously referred to as Yellow signals.)

Receiver Overload Receiver overload is the maximum acceptable value of the received average power at point R to achieve a 1 x 10-10 BER.

Receiver Sensitivity Receiver sensitivity is defined as the minimum acceptable value of average received power at point R to achieve a 1 x 10-10 BER.

Reference Clock A clock of very high stability and accuracy that may be completely autonomous and whose frequency serves as a basis of comparison for the frequency of other clocks.

REG A device that performs regeneration.

Regeneration The process of receiving and reconstructing a digital signal so that the amplitudes, waveforms and timing of its signal elements are constrained within specified limits.

Revertive Switching In revertive switching, there is a working and protection line or unit. Services always revert back to the original working line or unit if the switch requests are terminated. When the working line or unit has recovered from the fault or the external request is cleared.

Ring Network One type of network that all network nodes are connected one after one to be a cycle.

Ring Segmentation When multiple ring switches are performed in response to multiple protection switch initiations, the original ring can be divided into two or more smaller rings. If more than a single pair of ring switches are performed on the original ring, the ring is said to be segmented.

Route The path a trail takes.

RS-232 In the asynchronous transfer mode, there is no hand-shaking signal. It can communicate with RS-232 and RS-422 of other stations in point-to-point mode and the transmission is transparent. Its highest speed is 19.2 kbps.

Simple Network Management Protocol

An IETF protocol for monitoring and managing systems and devices in a network. The data being monitored and managed is defined by a Management Information Base (MIB). The functions supported by the protocol are the request and retrieval of data, the setting or writing of data, and traps that signal the occurrence of events.

Appendix A: LoopStar 800 Glossary

LPS800-UM-PERF-04 A-15

Small Form-Factor Pluggable

A specification for a new generation of optical modular transceivers. The devices are designed for use with Small Form-Factor (SFF) connectors and offer high speed and physical compactness, and are hot-swappable. SFP transceivers are expected to perform at data speeds of up to five gigabits per second (5 Gbit/s) and possibly higher. Because SFP modules can be easily interchanged, electro-optical or fiber optic networks can be upgraded and maintained more conveniently than has been the case with traditional soldered-in modules. Rather than replacing an entire circuit board containing several soldered-in modules, a single module can be removed and replaced for repair or upgrading. This can result in a substantial cost savings, both in maintenance and in upgrading efforts.

SONET Add-Drop Multiplexer

A Network Element that provides either one or two "high-speed" SONET interfaces, as well as "tributary" interfaces at one or more of the various rates supported in the digital network.

Span The set of SONET lines between two adjacent nodes on a ring.

Span Switching In a 4-fiber BLSR, the working and protection channels are carried over different lines. Thus a 4-fiber ring may allow protection similar to 1:1 point-to-point protection switching on individual spans. For failures that affect only the working channels (e.g., a single fiber cut), the restoration can be performed by switching the working channels to a different line carrying protection channels on the same span. Hereafter, when used in context with ring architectures, this type of switching is called span switching to avoid confusion. The actual protocol for span switching is part of the BLSR protocol and differs from the protocol used in point-to-point APS systems. Span switching is not applicable for 2-fiber BLSRs.

Squelching Traffic Replacing traffic by the appropriate path AIS to prevent misconnections. STS level squelching occurs only into and out of the protection channels (working channels are never squelched).

SSM Synchronization Status Message. ITU-T defines S1 byte to transmit the network synchronization status information. It uses the lower four bits of the multiplex section overhead S1 byte to indicate 16 types of synchronization quality grades.

STM-N Synchronous Transport Module. An STM is the information structure used to support section layer connections in the SDH. It consists of information payload and Section Overhead (SOH) information fields organized in a block frame structure which repeats every 125 ms. The information is suitably conditioned for serial transmission on the selected media at a rate which is synchronized to the network. A basic STM is defined at 155.520kbit/s.

Subnet The logical entity in the transmission network and comprises a group of network management objects. A subnet can contain NEs and other subnets. A subnet planning can enhance the organization of a network view.

Subnet Mask Also referred to as the network mask off code. It is used to define network segments so that only the computers in the same network segment can communicate with one another, thus suppressing broadcast storm between different network segments.

Support The frame on the bottom of a cabinet when installing the cabinet on the antistatic floor.

Switching Priority The rule that should be set when several protected boards need to be switched. If the switching priority of each board is set the same, the tributary board that fails later cannot be switched. The board with higher priority can preempt the switching of that with lower priority.

Synchronous A network where transmission system payloads are synchronized to a master (network) clock and traced to a reference clock.

Synchronous Digital Hierarchy

A hierarchical set of digital transport structures standardized for the transportation of suitably adapted payloads over physical (primarily optical) transmission networks.

Synchronous Payload Envelope

The major portion of the SONET frame format used to transport payload and STS path overhead. A SONET structure that carries the payload (service) in a SONET frame or virtual tributary. The STS SPE may begin anywhere in the frame’s payload envelope. The VT SPE may begin anywhere in a floating mode VT, but begins at a fixed location in a locked-mode VT.

Synchronous Transport Signal Level 1

The basic (functional) module used to build SONET signals. An STS-1 has a bit rate of 51.84 Mb/s, and may be converted to an OC-1 or STS-1 electrical interface signal, multiplexed with other modules to form a higher rate (STS-N) signal, or combined with other STS-1s to form an STS-Nc.

Synchronous Transport Signal Level N

A (functional) module used to build SONET signals. An STS-N has a bit rate of N’51.84 Mb/s, and may be converted to an OC-N or STS-N electrical interface signal, or multiplexed with other modules to form a higher rate signal (in which case it is referred to as an STS-M).

TTCP/IP Transmission Control Protocol/Internet Protocol. Common name for the suite of

protocols developed to support the construction of worldwide internetworks.

Test Access Test Access usually refers to DS1 and DS3 Test Access. Test access, a traditional DCS function, allows the user visibility into any VT1.5/STS-1 signal in the network. Test access aids users in turning up connections and in identifying faults in existing service connections. DMX supports two different types of test access. The non-intrusive method simply taps the VT1.5/STS-1 channel as it passes through the system and routes it to an external testing device. The more intrusive mode splits the VT1.5/STS-1 from the incoming signal and sends it to an external testing device. Test access facilitates DMX functioning in a DCS application.

TID Target Identifier. It is a destination code in the form of a valid simple or compound TL1 identifier or text string, limited to 20 characters, including the CLLI code.

Timeslot Single timeslot on an E1 digital interface (a 64-kbps, synchronous, full-duplex data channel) typically used for a single voice connection.
