DC Power Supply Unit - DPU22 The DC Power Supply Unit (DPU22) is a part of the common unit of TJ1400P network element. The DPU22 supports load sharing on redundancy basis i.e. if one PSU fails, other will be the active load driver and provides a stable DC power to other cards in the system. The DPU22 is also referred as PSU. The PSU delivers 100 W power output and an output voltage of 12V ± 10% DC.

DANGER: Do not jack-in/jack-out PSU card in the system with Power Cable connected. PSU has high energy and/or voltage level that can cause serious electrocution or burn.

CAUTION: This equipment might have more than one power supply connection. All connection must be removed to de-energize the unit before accessing internal parts for maintenance or service.

STATIC DISCHARGE DAMAGE: Static charge can damage the equipment. While handling cards for making system interconnections, wear an ESD strap to discharge the static buildup.

HOT SURFACE: Do not touch the heat sinks on the unit just after removal.

Alarm-In: Four user configurable alarm inputs are provided. The alarm inputs connect external triggers for events (such as open door or a shelf high temperature, A/C failure) to the OAM card. When an event occurs, which activates the trigger connected to the external alarm input, the network element raises an environmental alarm. The Alarm-In interface is through a RJ-45 connector. Opto-couplers are provided to protect the FPGA from overvoltage damage.

Alarm-Out: The alarm outputs can be used to trigger the operation of external equipment, such as a generator, fan or audible alarm. The alarm outputs are caused by alarms detected by the network element. The alarm-outs are classified as minor, major and critical. The Alarm-Out interface is through a RJ-45 connector.

DIAG/ToD Interface

The DIAG/ToD interface is a RJ-45 connector. This interface offers a serial connection to node using which a user can launch a terminal session to log onto the Operating System.

NOTE: The diagnostic interface is meant for use by authorized Tejas Networks personnel only.

C CSMA/CD

Carrier Sense Multiple Access/Collision Detection (CSMA/CD) are a set of rules determining how network devices respond when two devices attempt to use a data channel simultaneously (called a collision). Standard Ethernet networks use CSMA/CD to physically monitor the traffic on the line at participating stations. If no transmission is taking place at the time, the particular station can transmit.

Light Emitting Diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. LEDs are used as visual indicators in network elements.

N NMS

Network Management System (NMS) provides an integrated management of Element Management Systems (EMS) across an intelligent optical network. NMS collects and represents management data from geographically dispersed EMSs on to a centralized database.

O OAM

Operation Administration Maintenance (OAM) is a group of management functions that provide node or network the functionality of fault indication, performance monitoring, security management and diagnostic functions. It is a popular framework among service providers for their network management systems.

P PCM

Pulse Code Modulation (PCM) is a digital representation of an analog signal where the magnitude of the signal is sampled regularly at uniform intervals, then quantized to a series of symbols in a digital (usually binary) code.

PDH

Plesiochronous Digital Hierarchy (PDH) is a technology used in telecommunications networks to transport large quantities of data over digital transport equipment such as fibre optic and microwave radio systems. It is the conventional multiplexing technology for network transmission systems.

Glossary of Terms

S SDH

Synchronous Digital Hierarchy (SDH) is an international standard for high speed synchronous data transmission over optical/electrical networks which can transport digital signals in variable capacities. It is a synchronous system which intend to provide a more flexible and simple network infrastructure.
