1 GENERAL

ADC PatchSwitch Digital Patching with RS-232/V.24, X.21, and V.35 Switching equipment, hereinafter referred to as PatchSwitch or PS, provides convenient access to RS-232 (ANSI/EIA232) or CCITT V.24, X.21, or V.35 circuits for patching or switching to allow monitoring, testing, and reconfiguring of a communications network. The V.35 description is located in Section 3. The X.21 description is located in Section 4.

Note: The PatchSwitch equipment described in this manual conforms to EIA/CCITT (RS232/Recommendation V.24), interface between Data Terminal Equipment (DTE) and Data Communication Equipment (DCE) known as the Serial Binary Data Interchange or SBDI.

The PatchSwitch product line is a flexible, modular system providing the following features:

1.Monitoring of digital communications leads without circuit interruption;

2.Line access and switching on data communications circuit directed toward two (A/B) equipments at the DTE end and as directed toward the modem at the DCE end;

3.Loss of monitored signal alarming circuits which identify the down circuit with either or both visual and audible indications;

4.Optional signal monitoring and alarming of eight different RS-232 signal lines;

5.Optional interlocking in groups of two to 16 modules with A/B switching;

6.Optional interlocking in groups of two to 16 chassis with A/B switching;

7.Optional test module with three (3) RS-232 female ports for convenient interface with compatible test equipment, with or without lead status monitoring LEDs (8-leads monitored);

8.Flexibility of the modular system approach allows the addition of chassis and modules and the interchange of modules on a single line basis;

9.Module replacement or removal with no need for rear cable disconnection;

10.All female DTE and DCE connectors or female DTE and male DCE connectors;

11.High density chassis occupies 7 inches (17.78 cm) in height within a standard 19-inch (48.26 cm) wide rack;

Page 1-1

2 PURPOSE AND SCOPE

The purpose of this manual is to provide the user with information necessary to install and operate the PatchSwitch equipment. Section 1 is a general description of the PatchSwitch equipment.

2.1PatchSwitch Assembly Configurations

Prepackaged standard product PS assemblies are configured as listed in Table 1-1. All assemblies contain 16 PS modules in the leftmost 16 positions of the 18 position chassis. The 17th position contains a blank panel and the 18th position contains the PS Chassis Control Module. Each of the 16 modules provides patching and/or A/B (A channel DTE or B channel DTE) fallback switching for all 23 leads of an RS-232/V.24 or V.35 circuit. Bank switching, switching operation enable, and master alarm reset are all provided for in the Control Module of the PS Chassis. Each module may be configured as part of an interlocked group.

Only one module of an interlocked group can be in the B state at one time. Each assembly has a blank designation strip for operator labeling of the circuits. The PS assembly has two main functions. First, it allows a user to select from two DTE channels to be connected to a DCE. Secondly, it allows the user to monitor and restore data channels through the use of manual patching. The PS assembly gives positive indication of the current DTE channel in use and allows the operator to switch all 16 channels in the PS assembly with a single switch (bank switch). With user selectable serial remote control, the switching function can be located up to 1,000 feet away for the PS chassis assembly. With user selectable dc controlled bank switching, the bank switching function can be located up to 500 feet away.

ADCP-50-304 • Issue 19 • June 1999 • Section 1: Introduction

The Interlocked group feature protects a device used as a substitute. A spare device may be connected to the DTE-B port of several A/B switching modules as shown in Figure 1-1. The A/B Interlock Jumper of each module in the group must be in the same position. When one device fails, the spare device may be substituted. Now, If another device fails, the interlocked group feature prevents the spare from being substituted for the second failed device.

2.2.1PatchSwitch Chassis

The PS chassis is the standard EIA 19-inch rack mounted unit with a backplane and space for 18 modules. The early chassis (PSC-01 and PSC-02) can be identified by the six pin in-line power connector located on the back upper left corner of the chassis. The later chassis (RDC-01 and RDC-02) can be identified by the nine pin square power connector located on the back upper left corner of the chassis.

The RDC-01/02 backplane consists of a printed circuit board assembly with eighteen 96-pin connectors on the inside of the card cage and 50 D-subminiature (DB) 25-pin connectors, two (DB) 9-pin connectors, one 20-pin dual in-line (DIN) connector and one 9-pin square connector on the back of the board.

2.2.2PatchSwitch Control Module (RDM-15B)

Manual operation of the PatchSwitch Control Module switches provides local control of the switch and alarm functions. The Control Module is microprocessor-based and provides the interfacing capabilities for both manual, dc pulse bank switching and remote control operations. A four-position DIP switch on the Control Module encodes the chassis identification number. Remote control devices use this number to select the PS chassis (see Table 6-1). The Control Module is located in position 18 (slot 18) of all PatchSwitch chassis.

_________________________________________________________________________________________________________

1 GENERAL

This section describes how the PatchSwitch equipment functionally operates in a data communications network. The PS equipment provides two main functions. A user selects one of two DTE data channels to connect to a DCE. Additionally, the user can monitor and restore data channels with a manual patch.

2 PATCHING WITH IN-LINE A/B SWITCHING

A functional diagram illustrating patching with in-line A/B switching is shown in Figure 2-1. Computer access is through the COMPUTER patch cord jack and either the DTE-A or DTE-B jack. Modem connection is through the MODEM patch cord jack and the DCE jack. Monitor connection is through the MONITOR patch cord jack.

3 A/B SWITCHING WITH OFF-LINE MONITOR ACCESS

The capability for accessing the off-line DTE device is illustrated in Figure 2-2. The upper port

(A) provides patch cord access to the upper “D” subminiature connector (J-1) on the chassis rear panel. When the module is in the “A” or normal state, this provides a monitor function. If the module is in the “B” or “sub” state, this provides direct test access to the off-line device.

The middle port (B) functions in the same manner for the middle connector (J-2) on the chassis backplane; “B” state, monitor access. “A” state, test access to the off-line “B” device.

The lower port (C) provides “intrusive” test access to the lower (J-3) connector on the chassis backplane. Insertion of a patch cord in this port, regardless of switch status, breaks the circuit and connects the patch cord to the common (DCE) device.

Figure 2-2. PatchSwitch with Off-Line Access (PSM-04, PSM-05)

3.1PS Control Module (RDM-15)

The PS Control Module (CM) controls the overall manual operations of the modules contained in the PS chassis. Three toggle switches located on the front panel have the following functions:

1.Bank switch all PS modules to either the “A” or “B” position. That is, switch all modules at the same time to either the “A” position or “B” position.

2.Enable the bank switch and the individual module A/B switches.

3.Reset all of the modules' alarm circuits.

The audible alarm circuitry is in the CM. It activates when an individual PS module detects an alarm condition (according to the alarm selection configuration on the module). Alarm conditions are detected only by modules which contain circuitry. The alarm circuitry must also be conditioned by proper strapping (jumper) of the individual PS chassis module.

When the alarm condition occurs, the individual module energizes its yellow LED indicator and the CM audible alarm sounds. The operator toggles the reset switch to reset the alarm circuitry.

The PS Control Module is equipped with a selectable remote control feature. Depending on the strap position the CM will either accept serial RS-422 or dc level (pulse) signals through the 9- pin D-subminiature connector. The CM is shipped strapped for RS-422 control.

With the CM strapped for serial RS-422 remote control, the CM provides an interface between the PS chassis modules and a remote control device (see Figure 2-3 and Figure 2-4). The following devices can be used for remote control of a PS chassis.

1.PatchSwitch Remote Control Unit (RCU, PSR-03) (See ADCP-50-302 User Manual.)

2.Terminal or computer (asynchronous ASCII device).

Page 2-3

© 1999, ADC Telecommunications, Inc.

ADCP-50-304 • Issue 19 • June 1999 • Section 2: Functional Description

A remote control device can control the operation of up to 16 full PS chassis assemblies (16 modules each) using a dedicated communications channel. This channel has four signals:

1.Transmit Data (TD)

2.Receive Data (RD)

3.Clear-To-Send (CTS)

4.Request-To-Send (CTS)

Each of the above signals has the same function as the corresponding signals defined by the RS232 standard.

The communications channel transmission medium is a cable consisting of four twisted wires within an overall shield. The shield is ground potential.

Note: The electrical characteristics of the communications channel cable (9-wire) conform to RS-422A/V.11 (X.27) standards.

Each PS chassis contains two female 9-pin D-subminiature connectors wired in parallel. A cable connects one PS chassis to another in daisy-chain fashion. A long cable connects the remote control device to the first (or last) PS chassis in the chain. Up to 16 PS chassis may be interconnected via the communications cable to a remote control device.

All transmissions between the PatchSwitch Control Module and the remote control device must use the ASCII character set. The PS chassis is a DCE device and has the following data transmission characteristics:

1.Speed of 1200 bits per second

2.Asynchronous transmission

3.Bit-serial ASCII data (8 bit no parity)

4.One Stop bit.

During normal operations, only one (of the possible 16) PS chassis CM may transmit on the communications channel at one time. When a PS Chassis is selected by the remote control device, all other PS chassis connected on the same channel are disabled (de-selected). All manual controls on a CM are always functional.

With the CM strapped for dc pulse control, the CM provides capability to bank switch PS chassis modules by application of 0V (GND), +5V or –5V to –48V dc voltage levels on the 9-pin D- subminiature connector. The connector pin assignments are detailed in Table 2-2.

Note: The dc voltages indicated in Table 2-2 must be present for a minimum of 250 msec to ensure switching.

Up to four (4) PS chassis can be bank switched by daisy chaining the CMs via the 9-pin D- subminiature and ensuring that each CM is strapped for dc pulse control.

The CM is also equipped with a selectable Autofallback feature. When an alarm condition is detected, automatic switching is performed between the “A” and “B” sides of the PS modules. The “A” to “B” side, or “B” to “A” automatic switching operation is selected by installing a jumper on the CM circuit board. After configuring the Autofallback option, the PS module detecting the alarm switches to the designated side (depending on the strap installed), it remains in the switched position regardless of subsequent alarm status.

Alarm indications are automatically reset after the module detecting the alarm switches to the appropriate side if the module is strapped for “Automatic Reset” (recommended). When the front panel alarm (ALM) selection is positioned in the OFF position, the autofallback feature is disabled for that module.

3.2LED/Alarm Patch Module with A/B Switching and In-Line Patch Access (PSM-01)

This PS module provides patching and switching functions together with lead status, switch status, and alarm indications. A simplified circuit of this module is shown in Figure 2-5.

The A/B switch activates relays to connect the computer patch cord jack either the DTE-A port or the DTE-B port. The indicators show A/B switch position, alarm and RS-232 lead status.

Figure 2-6 shows a more detailed diagram of the module. In addition to switching between DTE-A or DTE-B, the relays also switch in the interlock jumper. Interlocking is used to protect the user from accidentally switching a common backup piece of equipment onto two or more different data lines. This is accomplished by allowing only the first module in that group to switch. The remaining modules remain in the “normal state” or the “A” position. Modules in the “B” position once switched to “A” will remain in the “A” position.

The three classes of interlock groups available are:

1.Global Interlock: Groups 1 and 2 are global and may be extended to all chassis in a system, using a 20-pin interchassis interlock cable. With this grouping, all modules having a jumper placed on group 1 make up one group, and all modules with a jumper on group 2 make up the other group. Interchassis interlock cables must be installed between chassis. Each module interlock group may have no more than one jumper installed at a time.

2.Horizontal Interlock: Groups 3 and 4 are horizontal and they include only modules in the individual chassis. With this grouping, all modules having a jumper placed on group 3 make up one group, and all modules with a jumper on group 4 make up the other group. These groupings do not extend out of the chassis and are not affected by the interchassis interlock cable. Each module interlock group jumper block may have no more than one jumper installed at a time.

3.Vertical Interlock: The vertical interlock jumper position is labeled V. Placing a jumper in this position interlocks all modules in the same slot location in other chassis having a jumper installed on the same V position. Interchassis interlock cables must be installed between chassis. The interchassis interlock cable is a 20 position ribbon cable (4WC-03) with a 20-pin connector for each chassis. Each module interlock group jumper block may have no more than one jumper installed at a time.

LEDs show the status of eight RS-232 leads. Each lead has a jumper connection to the alarm circuit control logic. The alarm is thus user selectable for any of eight leads. The EIA RS-232/ CCITT V.24 modem interface signal leads are shown in Table 2-3. The alarm circuit control logic supplies the alarm signal to the control module and an alarm indicator. This logic is also controlled by the RST (Reset) touch switch, toggle switch OFF (LED off, audible alarm off), ALM (LED and audible alarm on) and LED (LED on, audible alarm off), and rotary switch DLY (alarm time delay setting). The alarm may be automatically reset if the automatic alarm reset jumper is in place. LED status indicators with their color and signal definition is shown in Table 2-4. Table 2-5 shows the alarm delay settings.

Caution: The bank switching feature is not compatible with the group interlock feature. If no module in an interlocked group is in the B state when a bank switch to the B state is initiated, only the first module in this group will switch to the B state. Data may be lost when more than one module is in the B state of an interlocked group. If one module in an interlocked group is in the B state when a bank switch is initiated, the rest of the modules in that interlocked group do not switch to the B state; consequently, the system maintains its integrity.
