CHAPTER 2: Introduction

2. Introduction

The Pro Switching System is an advanced system for managing data lines and data networks. It has a broad range of capabilities and can adapt to small and large applications.

Once you set up the system, it provides “hands-free” management. The predefined switching and backup tasks are performed automatically. If a line generates an alarm, the system reroutes the data through a backup line and reports the problem. Also, it lets you monitor and test any line in the network.

For remote management, the 2000 Windows SNMP OpenView 7.2 application software lets you control racks via SNMP over IP networks.

The Pro Switching System features:

Functions:

• Three- and four-cavity patching

• A/B switching

• Single-line, gang, and group switching

• User-defined alarms

• Alarm- and time-triggered switching

• Remote status monitoring for testing faulty lines

• Break to DTE or DCE for remote test/access

• Non-intrusive bridging for monitoring

Hardware:

• Intermixing of switching and patching cards within the same rack

• Digital and analog monitoring buses

• Switching performed via latching relays

• Redundant power units with separate power feeds

• Dimensions: 19" (48.3 cm) wide, 8.75" (22.2 cm) high, 13.25" (33.7 cm) deep.

PRO SWITCHING SYSTEM

Control/Software:

• SNMP

• PC (HP OpenView Windows)

• ASCII character strings

• Async terminal menus

• Central control of remote test equipment

• Provides database including network performance evaluation

The rest of this chapter describes the features of the Pro Switching System in more detail. It also provides sample applications at the end of the chapter. Read this chapter for a more comprehensive understanding of the system.

2.1 System Architecture

The System architecture of the Pro Switching System has three levels: line level, rack level, and site level.

At the Line level, data lines pass through line cards.

Figure 2-1. Line Level.

CHAPTER 2: Introduction

The line level has the following capabilities:

• A/B switching

• Two-, three-, and four-cavity patching

(Refer to Chapter 3, Functions, for descriptions.)

At the Rack level, the line cards are mounted in racks. Each rack has its own

microprocessor-based control card.

The rack level has line bridging and breaking via monitoring bus.

(Refer to Chapter 3, Functions, for descriptions.)

Figure 2-2. Fully Loaded Rack.

At the Site level, each rack control card communicates with a system management device (for example, a PC).

The site level has the following capabilities:

• group switching

• scheduled switching

• default switching

• alarm monitoring (reporting to system management and selectively to customer courtesy terminals)

• alarm-triggered switching, with or without fallback

PRO SWITCHING SYSTEM

Figure 2-3. Site Level.

• system health check

• database report generation

• system security functions (software and hardware pass codes)

• multiple site management (up to 256 racks per site; up to 256 sites per system)

(Refer to Chapter 6, Operation, for descriptions.)

2.2 Hardware Features

2.2.1 TWO-P

ARTCARDDESIGN

A unique two-part card design provides flexibility. The front card (front-inserted) plugs into the rear card (rear-inserted) (see Figure 2-4). Together, they manage one data line.

Generally, the front card contains the switching and patching circuitry, and the

rear card contains the cable interface circuitry.

Network

You can insert and remove front cards without removing rear cards or cables.

Figure 2-4. Front and Rear Cards.

2.2.2 F

RONT-REARCARDCOMBINATIONS

Each front card is compatible with a specific rear card.

2.2.3 S

UPPORTEDINTERFACES

The system supports the following interfaces: RS-232/V.24, V.35, RS-530, DB15, RJ11, RJ-45.

2.2.4 S

UPPORTEDCONNECTORS

The system supports these connectors: DB25, V.35 “M” type, DB15, RJ-11, RJ-45.

Figure 2-5 illustrates the mixing of connectors in a rack.

PRO SWITCHING SYSTEM

2.2.5 L

INECARD

WITCHES ANDINDICATORS

Each Switching card has a switch on the front panel for manual control. Each card also has LED indicators.

(Refer to Chapter 4, Components, for a full description of line card switches

and LEDs.)

2.2.6 C

ONTROLCARDSWITCHES ANDINDICATORS

The rack control card has a five-button switch panel for gang switching (see Figure 2-6). You can enable/disable this function by a key switch. When you press a button, all cards in the rack that have the indicated capability switch.

For example, if you press the B button, all A/B switching cards in the rack will

switch to B.

Switching is performed by latching relays, which, if the power fails, remain in

the last switched position and continue to pass data.

The control card also has a Lamp Test button to test the rack LEDs. A reset button reboots the system (warm or cold reboot, depending on a DIP-switch setting).

Control Card LEDs indicate Power Supply, Fan, and System Status.

2.3 System Management Features

2.3.1 HP O

PENVIEWWINDOWSGRAPHICINTERFACE

Pro Switching System software running on a PC under HP OpenView for Windows mediates System Management.

OpenView is an open software product, allowing you to manage devices from different vendors. It allows you to create a map of the network using a supplied set of icons. A color code indicates the status of each device in the network.

The Pro Switching System network management can control up to 256 sites, each comprising up to 256 interconnected racks. You interact with the system via the map icons and a series of subordinate screen displays.

PRO SWITCHING SYSTEM

The displays include realistic front and rear views of the rack mount and the line cards. They show the current switched state of all lines and the status of monitored leads.

The screen displays functional switch buttons. If you click on a displayed button, the equivalent hardware operation occurs at the site. For example, if you click on gang-switch button A, a gang switch to A operation occurs at the rack (as long as the key switch is in the ENABLE [unlocked] position).

The software also displays LEDs in real time. In other words, when an LED lights at a rack, it also lights in the on-screen display.

If you click on the display of a line card, the system displays a window that describes the line and the status of the monitored signals on the leads.

2.3.2 M

ONITORING/TESTING

Two common monitoring buses—a digital bus and an analog bus—provide access for monitoring and testing each line with or without interrupting data flow.

Upon command, the system can connect a line on any rack to the rack’s digital or analog monitoring bus.

When the monitoring buses of several racks are daisy-chained together, you can create a bus definition, specifying the racks that are connected in this way. This gives you easy access for monitoring bus operations. See Figure 2-7 for an example of a monitoring bus.

Figure 2-7. Monitoring Bus.

CHAPTER 2: Introduction

2.3.3 A

LARMING

You can define failure criteria for each signal online, based on the sensing of SPACE, MARK, or NO DATA conditions and their duration. You can define different criteria for different times of the day.

2.3.4 A

LARM

A port can be dedicated to let you connect an alarm box. The alarm box responds to alarm signals received by the PC, producing a visual or auditory signal to alert you.

2.3.5 A

LARM

-T

RIGGEREDSWITCHING

You can predefine a lead alarm to trigger specified switching operations whenever it occurs. You can also program the system to switch back when the condition has been corrected. You can define different criteria for different times of the day.

2.3.6 S

WITCHINGOPTIONS

You can apply PC-controlled switching operations—manual, backup, alarmtriggered, scheduled, and default (single-keystroke)—selectively to one line at a time, if desired. You also can create and name groupings of sites, racks, and/or lines to switch simultaneously.

2.3.7 N

ETWORKSECURITY

You assign each user a password and an appropriate level of access to network operations.

2.3.8 C

USTOMERACCOUNTIDS ANDCOURTESYTERMINALS

You can define customer account IDs for assignment to one or more lines and/or racks. This assignment enables selective routing of status and alarm information to one or more courtesy terminals. Customers viewing courtesy terminals can observe what is happening on their own lines but not on the lines of other customers.

2.3.9 R

EMOTE

You can connect one or more remote PCs to the dedicated communication ports. A user at a remote PC can perform switching, and can view and acknowledge alarms in the same ways as the user at the central PC.

PRO SWITCHING SYSTEM

2.3.10 O

PENCOMMUNICATIONPORT

The Open Communication Port function lets you select one of the system’s communication ports to which a modem or terminal is connected. Then, via the PC, you can communicate directly with the connected device.

2.3.11 O

PEN

HANNEL TOMODEM

At the PC, you can open a channel to any online modem and communicate directly with the modem for non-intrusive testing and diagnosis.

2.3.12 N

ETWORKHEALTHCHECK

To detect rack failures that preclude alarms, the PC runs a health check, attempting to communicate with each rack. If a rack fails to respond, the PC reports this failure.

Sites that are always online with the central PC are checked continuously. For off-line sites, you can define a Health Check Schedule, specifying times when these sites will be checked.

2.3.13 H

ISTORYFILES

All alarms are written to the Session Alarm History file, which you may display and/or clear at any time.

Alarms are also written to a separate ASCII log file on the hard disk. Another ASCII log file maintains a record of important system events and operator actions.

2.3.14 W

ATCHDOGTIMER

The optional Watchdog Timer application switches users between two computer systems, substituting a standby system for a failed system.

2.4 Control Communication

2.4.1 R

ACKS AND THEMANAGEMENT

PC ATS

ITES

A Pro Switching System rack that is connected via its COMM IN port with the management PC comprises a Pro Switching System site. The rack connected in this way is the Primary Rack. At this site, other racks called Secondary Racks can connect to the Primary Rack via their communication ports in daisy-chain fashion.

The location of the Management PC is referred to as the Primary Management Site. The Management PC can communicate with up to 256 Pro Switching System sites. This communication can be routed through the communication ports of the

CHAPTER 2: Introduction

PC or through up to 64 auxiliary communication ports mounted on intelligent serial multi-port units.

The connections between the PC and the rack can be of two types:

1. Dedicated line between the PC and a site. The site is always online with the PC (hardwired).

2. Dialup modem connection between the PC and a site (see Figure 2-8). The connection is established when needed.

You can program communication ports from the PC to be either dedicated

ports or dialup modem ports.

Figure 2-8. Dialup Connection.

2.4.2 D

IALOG WITHDIALUPSITES

Normally, all dialup sites are off-line. You initiate the dialing of the site’s telephone number when you execute a command that requires communications with a rack on a dialup site. When the connection is established, the remote site comes online and polling starts.

From the moment you make the connection, you can send commands to the

racks on that site and receive status data from the racks.

PRO SWITCHING SYSTEM

If an alarm is generated or restored to normal in a rack at a dialup site, and the site is off-line, the dialup site dials the central PC.

When the connection is established, the dialup site comes online. The PC responds to the connection by polling the dialup site and obtaining information about current status and configuration. Then, the PC disconnects the dialup site.

2.4.3 P

OLLINGPROCEDURES

Generally, racks on dedicated ports are polled individually by the PC. However, if a switching/monitoring screen for the rack is displayed, this rack is polled more frequently in order to acquire “real-time” information about it for display on the screen.

2.5 System Expansion

The Pro Switching System is flexible and modular. You can begin with a small local system—a rack and a few cards. As your needs grow, you can add more cards and racks to create a large site; then add more sites to create a global network. You can incorporate new functions and interfaces as they come into use.

CHAPTER 3: Functions

3. Functions

This chapter describes the functions of the Pro Switching System, including switching and patching options and the monitoring bus. The chapter also describes the system configuration options.

3.1 Switching and Patching

The Pro Switching System offers these switching and patching options:

• A/B switching

• Three-cavity patching

• Four-cavity patching

3.1.1 A/B S

WITCHING

A/B switches have three ports: A, B, and COMMON. You can connect the line at the COMM IN port to the line at the A port or the B port. Figure 3-1 shows an A/B switch in which the COMMON port is connected to the A port.

Figure 3-1. A/B Switching.

The switch uses latching relays, which remain in the last switched position if the

power fails.

A/B switches are available for use with the following interfaces: RS-232/V.24,

RS-530, V.35, DB15, RJ-11, and RJ-45.

3.1.2 T

HREE-CAVITYPATCHING

These cards have three patch cavities: COMP, MODEM, and MON. Figure 3-2 shows three-cavity patching. Normally, the DTE is connected to the DCE.

PRO SWITCHING SYSTEM

Figure 3-2. Three-Cavity Patching.

When you insert a patch cord into the MON cavity, it is connected to the circuit between the DTE and the DCE. This is a bridge connection, and the circuit is not broken. You can monitor the signals.

When you insert a patch cord into the COMP cavity, the circuit is broken and the cord is connected to the DTE. You can test the DTE.

When you insert a patch cord into the MODEM cavity, the circuit is broken and the cord is connected to the DCE. You can test the DCE.

Three-cavity patching is available for use with the following interfaces: RS-232, V.35, and RS-530.

3.1.3 F

OUR-CAVITYPATCHING

These cards have A/B switching and four patch cavities: COMP, MODEM, MON A, and MON B. Figure 3-3 shows four-cavity patching when the switch is in the A position. Normally, the appropriate DTE is connected to the DCE.

CHAPTER 3: Functions

Figure 3-3. Four-Cavity Patching.

When you insert a patch cord into the MON A cavity, it connects to the circuit between DTE A and the DCE. When you insert a patch cord into the MON B cavity, it connects to the circuit between DTE B and the DCE. The circuits are not broken. You can monitor the signals.

When you insert a patch cord into the COMP cavity, the circuit is broken and the cord is connected to the appropriate DTE. You can test the connected DTE.

When you insert a patch cord into the MODEM cavity, the circuit is broken and the cord is connected to the DCE. You can test the DCE.

Four-cavity patching is available for use with the following interfaces: RS-232, V.35, and RS-530.

3.2 Monitoring Bus

The Pro Switching System has two monitoring buses: a digital monitoring bus and an analog monitoring bus. You can connect a monitoring bus to any line in the system, allowing monitoring and testing equipment to access that line. When a line is connected to the monitoring bus, the corresponding card’s MONITOR LED lights. Figure 3-4 shows a monitoring bus.

Typically, the DTE is connected to the DCE.

PRO SWITCHING SYSTEM

You can connect the monitoring bus to a line in any of three configurations, which correspond to the patching functions. You can bridge, break to DTE, or break to DCE.

When you bridge a line, the equipment is connected to the circuit between the DTE and the DCE. The circuit is not broken, and you can monitor the signals.

When you break to DTE, the circuit is broken and the equipment is connected to the DTE. You can test the DTE.

When you break to DCE, the circuit is broken and the equipment is connected to the DCE. You can test the DCE.

The buses use non-latching relays, which return to their normal settings if the power fails.

The monitoring buses are available for use with the following interfaces: RS-232, RS-530, and RJ-11.

Figure 3-4. Monitoring Bus. The line card in slot 2 is configured for break

to DTE.

(All other line cards are normal-through.)
