IMPORTANTObserve all warnings in the text or on equipment labels regarding high-voltage or high-temperature conditions. The following warnings and figures apply to most Fujitsu products.

Plug-In Unit CautionsObserve the following precautions when handling plug-in units: Hold the plug-in unit only by its edges. Slowly and firmly push a plug-in unit into its slot to avoid damaging the unit. Do not force the unit. A slow insertion method minimizes power surges during installation. The longer ground connector pins ensure the ground circuit is connected first.

ESD CautionsUnits are stamped with anti-electrostatic markings (shown at right). Observe the following precautions to avoid damage from electrostatic discharge (ESD): Always transport and store the unit in an ESD approved shipping bag. Always wear an ESD wrist strap, with a minimum 1-megohm resistance, that is connected to safety ground. Do not use a damaged wrist strap.

CHAPTER 2 OC-3 Interface (3xx1) Unit Description Overview

2.1

OverviewThe OC-3 Interface (3xx1) units serve as an OC-3 tributary interface for FLASH-192 equipment and, through the Management Complex in the OC-192 Transport shelf, provide protection switching for network applications. Each unit can handle any combination of STS-1 and STS-3c signals, up to a maximum total bandwidth of three STS-1 channels. Paired 3xx1 units support both working and protection traffic in many network applications. Table 2-1 [p. 2-2] lists the versions of this unit covered in this Unit Description.Table 2-1: 3xx1 Unit Versions Unit Name3Lx1a 3Sx1aa

CHAPTER 2 OC-3 Interface (3xx1) Unit Description Features

2.2

FeaturesThe 3xx1 unit provides the following features:

OC-3 tributary interfaces Line protection switching Pointer processing

2.3

Physical DimensionsThe physical dimensions of the 3xx1 plug-in unit are as follows:

Width: 20 mm Height: 265 mm Depth: 230 mm

2.4

Functional DescriptionThe following subsections provide functional descriptions of the OC-3 Interface (3xx1) plug-in unit.

2.4.1

Receive Direction (Incoming OC-3 Tributary Signal)The incoming OC-3 tributary signal is converted to a serial electrical signal and then processed by the OC-3 interface section, where framing is located and loss of frame (LOF) and loss of signal (LOS) are monitored. The overhead is accessed and signal fail (SF) and signal degrade (SD) conditions are monitored. The overhead is passed to the Management Complex. The signal is then pointer processed to allow alignment with the system master clock. Finally, the signal is passed through the OC-48 Interface (MMx1/MSxn) units (colocated in the Optical Tributary shelf ) to the Routing shelf for distribution.

2.4.2

Transmit Direction (Outgoing OC-3 Signal)In a 1+1 system configuration, selection of traffic groups under control of the Management Complex (located in the OC-192 Transport shelf ) provides line protection and the underlying configuration for facility protection. Traffic from the MMx1 units is selected by the 1+1 selection section of the 3xx1 for processing within the 3xx1. The selected traffic from the MMx1/MSxn units is passed through the STS-3 pointer processor, where it is synchronized to the system master clock. After pointer processing, SONET overhead is added to the signal. The time-slot assignment (TSA) processing in the Routing shelf diverts selected STS channels to be dropped to the OC-3 facility.

2-3

CHAPTER 2 OC-3 Interface (3xx1) Unit Description Options

Finally, the signal is converted to a serial data stream, electrical-to-optical (E/O) conversion takes place, and the signal is transmitted over the OC-3 tributary.

2.4.3

Monitor and ControlOptical Tributary shelf functions are managed from the Management Complex, which is part of the OC-192 Transport shelf. The two shelves are linked by an HUBx/HEDx optical connection. In the 3xx1 unit, a control interface section (unit control) is provided for communication between the Management Complex and various sections within the 3xx1 unit. This control interface reports circuit and signal failures/degrades to the Management Complex. In addition, this interface accepts control message inputs from the Management Complex to provision the unit, operate protection switching circuitry, and turn on/off the indicator LEDs on the front panel.

2.4.4

Unit PowerEach unit is self-contained in the sense that it provides its own power conversion from the office power inputs. Both A and B office power and returns are accepted into the unit. Table 2-3 [p. 2-4] lists the typical and maximum power consumption for these units.Table 2-3: Power Consumption (Watts) Unit3Lx1 3Sx1

Typical14.3 14.1

Maximum14.5 14.3

2.5

OptionsAll options affecting the operation of the 3xx1 units are set during provisioning and are stored in memory in the Management Complex units. It is not necessary to perform any optioning activities when replacing a 3xx1 unit. Refer to FNC-570-0052-270, System Turn-Up Ring Configurations, Appendix A.

Functional DescriptionFigure 3-1 [p. 3-4] is a simplified block diagram of the AWU1.

3.4.1

Office AlarmsAudible and visual office alarm notifications are activated by signals from the Management Complex central processing unit(s) (CPU). The AWU1 CPU then activates the appropriate critical (CR), major (MAJ), and minor (MIN) visual and audible alarm relays and the corresponding LEDs on the front panel. Pressing the alarm cut-off (ACO) button on the front of the unit deactivates the audible alarm output relays and the ACO LED. This cut-off continues until the current alarm state changes, at which time the new status is indicated on all the audible alarm relay outputs, visual alarm relay outputs, and the front-panel LEDs.

3.4.2

Lamp TestA LAMP TEST control is provided to allow the technician to test the system LEDs. When pressed, multicolor LEDs (red, yellow, green) light in the yellow state. Single-color LEDs light in their designated color.

3.4.3

Abnormal Condition IndicatorThe following manual control conditions cause the ABN (abnormal) LED to light yellow on the AWU1.

CHAPTER 3 Alarm/Orderwire (AWU1) Unit Description Functional Description

3.4.4

Management Complex Failure IndicatorEight DC alarm lines from the units in the Management Complex are connected to the AWU1 unit to detect hard failures of management units.

3.4.5

OrderwireNote: Orderwire is supported in Releases 2.3, 4.2, 5.1, and 5.2.

The orderwire feature is available with all FLASH-192 configurations. The AWU1 passes E1 (local) and E2 (express) bytes received from the SONET line interfaces overhead to the orderwire conversion circuitry. These bytes then can be chosen for connection to the rear-panel connectors and/or for digital-to-analog (D/A) conversion to voice frequency (VF) for the telephone interface on the front panel and/or rear connector. Similarly, analog VF signals from the VF1 and VF2 connections on the rear panel and/or the telephone interface on the front panel are passed through the analog-to-digital (A/D) converter and converted to digital signals.Note: Release 5.2 software supports the E1 and E2 channels.

For additional details and specifications for orderwire functionality, refer to FNC-570-0052-120, Application Engineering, Section 6.10 [p. 6-29].

3.4.6

HousekeepingNote: Housekeeping functions are supported in Releases 2.3, 4.2, 5.1, and 5.2.

The housekeeping feature is available with all FLASH-192 configurations. Sixteen housekeeping alarm inputs are accepted from local external equipment. A change of state on one of these inputs informs the AWU1 of an alarm condition status change for the associated external equipment. This information is passed to the Management Complex CPU. Likewise, the Management Complex CPU controls activation of the four housekeeping control relays on the AWU1. For additional details and specifications for housekeeping functionality, refer to FNC-570-0052-120, Application Engineering, Section 6.9 [p. 6-27].

4.4

Functional DescriptionFigure 4-1 [p. 4-4] is a simplified block diagram of the C2x1 unit.

4.4.1

Receive Direction (Incoming OC-12 Tributary Signal)The incoming OC-12 tributary signal is converted to a serial electrical signal and then processed by the OC-12 interface section, where framing is located and loss of frame (LOF) and loss of signal (LOS) are monitored. The overhead is accessed and signal fail (SF) and signal degrade (SD) conditions are monitored. The overhead is passed to the Management Complex. The signal is then pointer processed to allow alignment with the system master clock. Finally, the signal is passed to the OC-48 Interface (MMx1/MSx2) units (collocated in the Optical Tributary shelf ) for transport.

4.4.2

Transmit Direction (Outgoing OC-12 Signal)In a 1+1 system configuration, selection of traffic groups under control of the Management Complex (located in the OC-192 Transport shelf ) provides line protection and the underlying configuration for facility protection. Traffic from the MMx1 units is selected by the 1+1 selection section of the C2x1 for processing within the C2x1. The selected traffic from the OC-48 Interface unit is passed through the STS-12 pointer processor, where it is synchronized to the system master clock.

ProcessorsThere are two processors used on this unit. The first is an MC68360, which is used to handle the first layer of software needed for the internal local area network (LAN), a modem interface, and the craft interface. This processor runs in the slave mode. The modem interface is terminated directly on CPU1. The main processor of the FLASH-192 system is the MC68040 device on this unit. It communicates with other processors and the peripheral hardware through the universal access bus (UAB). This processor terminates layers 4 through 7 of the Open Systems Interconnection (OSI) protocol stack for data communication channel (DCC), LAN, and X.25 ports. The current operating program is stored in the Flash memory designated as active. The previous version of the operating software is stored in the standby section of Flash memory. When software is downloaded into the unit, it is loaded into the standby Flash memory. Promotion of the downloaded software to the active status is partially accomplished by switching the designations of the active and standby memories. A real-time clock is used to provide timestamp information on performance and other status data when it is reported to the craft or other interfaces. A CPU reset button is provided on the front of the CPU1. Pressing the reset button with a thin tool, such as a ballpoint pen tip, causes the system processor to restart.

CHAPTER 7 Craft Interface (CRF1) Unit Description Overview

7.1

OverviewThe Craft Interface (CRF1) unit provides front-panel craft access for interface and processing for a local communication network (LCN) local area network (LAN), and X.25 data communications network (DCN). It also includes two OC-192 section data communication channels (SDCCs) in single OC-192 Transport shelf configurations and four OC-192 SDCCs in 4-fiber bidirectional line-switched ring (4F-BLSR). The fifth channel is reserved for OC-48, OC-12, or OC-3 SDCC. The part number for this unit is FC9511CRF1. Table 7-1 [p. 7-2] lists cross-references for additional information on this unit.Table 7-1: Additional Unit Information Cross-Reference Unit InformationPart number/ordering Compatibility Installation/removal procedures Replacement procedures Trouble-clearing procedures

Functional DescriptionFigure 7-1 [p. 7-4] is a simplified block diagram of the CRF1.

7.4.1

ProcessorsTwo on-board microprocessors provide the processing power for the CRF1:

The serial communication channels of the processors provide the terminations for four OC-192 channels (labeled SDCC 1 through SDCC 4 in Figure 7-1 [p. 7-4]), and one OC-48, OC-12, or OC-3 tributary channel (labeled SDCC 5 in Figure 7-1 [p. 7-4]). Channels 1 through 4 are assigned by the system as the OC-192 SDCCs are turned up by the user. Channel 5 is assigned by the system to the first tributary (OC-48, OC-12, or OC-3) SDCC turned up by the user.Note: An additional 15 SDCCs can be configured and provisioned if a DCC1 unit is present. An additional 30 SDCCs are possible with two DCC1 units.

The two microprocessors handle the communication interfaces with the X.25 and external 10Base-T LAN for use in communicating with remote systems.

7.4.2

Data CommunicationsThe DCC terminations provide the physical termination of the SDCCs. The external LCN LAN and X.25 DCN provide operations communications with other network elements (NEs) and systems. The LAN conforms to the 10Base-T standard for 10-Mb/s Ethernet. The X.25 interface conforms to RS-422 electrical standards and provides the link access procedure-balanced (LAPB) protocol termination functionality. The data link and networking layers of the communication protocol are processed by the central processing units (CPUs). These layers process the data packets and route them to the appropriate channel or to the main CPU if destined for the local NE. The internal LAN port is used for routing message traffic between the DCC, craft interface, and CPU. It is also used for passing software between units during the software download process.

7.4.3

IndicatorsFront-panel LEDs indicate unit alarm, the logging on of a user through the craft interface, and the presence of a software download process from a remote site or from the craft interface port.
