2.1 PatchSwitch 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 enab le, and mast er ala rm reset are al l pro vid ed for in t he Control Module of the PS Chassis. Each module may be configured as part of an interlocked group.

Only one module of an interlock ed gr oup can be in the B stat e at one time. Eac h ass embly 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 operato r to switch all 16 channel s in the PS assembly with a si ngle 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 199 9 • Sec tion 1: In troduction

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 m ust 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.

2.2.1 PatchSwitch Chassis

The PS chassis is the stan dard EI A 19-in ch rack moun ted uni t wit h a ba ckplane and s pace f or 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-lin e (DI N ) con nector and one 9-pin squar e co nnector on the back of the board.

2.2.2 PatchSwitch 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 cap abilities for b oth m anua l, dc pulse bank swit ching and remote cont rol 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 netw ork. The PS equipment pro vide s two main f uncti ons. A user selec ts one o f two DTE data cha nnel s to connect to a DCE. Add it ion al ly, the user can monitor an d r es tor e dat a channels with a manual patch.

2 PATCHING WITH IN-LINE A/B SWITCHING

A functiona l diagram illustrati ng patching wi th in-line A/B swit ching 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.

The PS Contro l Mod ule (C M) c ontro ls the overall manu al o pera tions of th e mod ules cont ained in the PS chassis. Three toggle switche s l oca ted on the front panel have the fo ll owing functi ons:

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.

J1 DTE-A

J2 DTE-B

J3 DCE

1608-A

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 conditi on occurs, the individual module energizes it s ye ll ow 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 9pin 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

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 abo ve signals ha s t he same function as th e corresponding sig nal s 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 contro l device to the first (or last) P S chassis i n the chai n. Up to 16 PS chass is 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 –5 V to –48V dc voltage levels on the 9- pin Dsubminiature connector. The connector pin assignments are detailed in Table 2-2.

Note:

to ensure switching.

Up to four (4) PS chassis can be bank switched by daisy chaining the CMs via the 9-pin Dsubminiature 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 swi tc hes to t he designated side (dep endi ng on the strap install ed) , it re mains 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 posi ti one d in the

OFF

position, the autof al lback feature is

disabled for that module.

3.2 LED/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, th e rel ay s als o swit ch in th e int er lo ck ju mp er. Interlockin g is use d to pro te ct 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 r emain in the “no rmal sta te” or the “A” position. Modules in the “B” position once switched to “A” will remain in the “A” position.

Page 2-7

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

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-p in i nt er cha ssi s i nt er loc k cable. W it h t hi s gr ouping, all modules having a jumper placed on group 1 make up one group, and all modules with a ju mp er on gr oup 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 in terl ock ju mper po siti on is la beled V. Placi ng a jump er in this position interlocks all modules in the same slot location in other chassis having a jumper install ed on the same V position . Interchassis interlo ck cables must be installe d 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.2 4 modem interface signal l eads are shown in Table 2-3. The al arm 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

3.3 Patch Module with A/B Switching and In-Line Patch Access (PSM-02)

This PS module operates similarly to the PSM-01 by providing patching, switching, and switch status indicatio n, e xcept it does no t cont ain LED statu s indi cator s and alar m ci rcuitry. A detailed circuit diagram of this module is shown in Figure 2-7.

4 A/B SWITCHING MODULE (PSM-03)

This module provides A/B swit ching only. A simplified circuit diagr am of t his module is show n in Figure 2-8.

The A/B switch activates the A/B relays. The A/B relays complete the channel between the DCE and either DTE-A or DTE-B. The re lays also switc h in the interl ock jumper. Interlocking from the control mod ule protects the user fr om accidentally switchin g common backup equip ment onto two or more different data lines. The thre e classes of interlo ck groups available are:

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 in terl ock ju mper po siti on is la beled V. Placi ng a jump er in this position interlocks all modules in the same slot location in other chassis having a jumper instal led on the came V position. Interch assis interlock c ables must be inst alled 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.

8 TEST MODULE (PSM-12)

Test Module PSM-12 provides the user with RS-232/V.24 interface capabilities, status indicators for eight (8) leads and alarm conditions. A simplified block diagram illustrating the test module connections is shown in Figure 2-11. Two female RS-232/V.24 TEST ports, located on the rear of the test module, are available for connecting the test equipment. Another female RS-232/V.24 port and a patch jack are located on the module front panel. All four connectors are hardwi red in paral lel.

The eight RS-232/V.24 circuit leads having LED indicators are: TD; RD; DCD; SQ; RTS; CTS; DSR; and DTR. When a monitored circuit lead is active (signal present), the associated LED indicator turns on (only while the signal is present). The colors and signal definitions for the applicable LED status indicators are detailed in Table 2-4.

An adjustable alarm circuit with associated LED (ALM), is provided to inform the user when a preselected alarm condition exists on one of the monitored leads. Each monitored lead has a jumper connection to the alarm circuit control logic. The alarm is user selectable for any one of the eight leads. The RS-232/V.24 interface signal leads are defined in Tab le 2- 3. The alarm circuit control logic supplies the alarm signal to the control unit and an alarm indicator.

1 PRODUCT OFFERING

The ADC V.35 PatchSwitch makes a v ailable four modules, four con v ersion boa rds and the n ecessary conv ersion pa tchcords for use with the 34- pin “V.35 Interface” data communications hardw are.

The units are designed to be compatible with the RDC-01, RDC-02, PSC-01, and PSC-02 standard PatchSwitch chassis. The V.35 modules utilize grey front panels so they can be mixed with other interfaces and still be identified a V.35 circuits. The modules provide monitor and patch access in the Serial Binary Data Interchange (SBDI) portion of data communications circuit. Some modules also provide local and remote alarming as well as signal status indication. A more detailed description of each module is given in Tab le 3- 1. The SBDI is typically found between the MODEM (DCE) and the TERMINAL/COMPUTER (DTE). A single circuit requi res one module and one conversi on board which conne cts betw een DTE-A or DTE-B and DCE. Switching takes place between DTE-A and DTE-B to connect to DCE. As an alternative to the V.35 conversion boards, V.35 cables using DB-25 connectors can be used to attach easily to the RDC-01/PSC-01 and RDC-02/PSC-02 PatchSwitch chassis.

ADCP-50-304 • Issue 19 • June 1999 • Section 3: PatchSwitch V.35

2 APPLICATION WITH EXISTING UNITS

The V.35 PatchSwitch modules can be identified by their gray color. A conversion board must be installed onto the chassis, as shown in Figure 3-1 and Figure 3-2, before the V.35 module assembly is placed into service. If the conversion boards are not practical, user cables can be manufactured by local sources to terminate the standard V.35 interface into a DB-25 connector which can then be connected directly to the RDC-01/PSC-01 or RDC-02/PSC-02 chassis. Standard pin arrangements for the V.35 interface to the DB-25 connector can be found in

Ta bl e 3 -2 . As defined further in this guide, optional leads are available on the conversion board

to allow for any six of the normally unused leads on V.35 to be passed throug h the module. This option allows the user to configure to his specific needs.

Once the V.35 module is in service, it's use is the same as a regular PatchSwitch module. Test equipment such as a data line monitor can be connected to the V.35 patch Interface modules or the LED/Alarm options on the PSM-18 can be used as diagnostic functions with the PS M-17 using patch cords from one other module to the other. The DTE-A/DTE-B ports on the PSM-16 and PSM-17 can be used to provide bridge monitor on activ e circuits or patching into the “C” port can split the circuit and isolate towards the DCE leaving the “A ” and “B” ports to isolate towards DTE-A and DTE-B respectively. The PSM-18 and PSM-19 interface modules can be used to attach to test equipment, patch in stand-by spare equipment, to be used as trunking jacks, or in the case of the PSM-18 LED/ALARM unit it can be used a diagnostic unit with the PSM-17.

The Pin pattern and identification is as noted above for the fifteen (15) leads unused from the V.35 connector and the six (6) leads unused through the patchi ng function. Any one of the fifteen leads to a maximum of six may be routed through the patch mechanism by means of straps if the user desires to bring more than the 19 lead V.35 interface through the patch mechanism. The procedure to follow to add a lead th rough the patch mechanism is simple. Assume you desire to bring lead EE through the patch mechanism on a DTE-A, DTE-B, and DCE module. Simply add a strap from E2 to EE on each of the three connector units on the FFM-01 or FFM-02 Subboard and lead EE is now routed through the patch mechanism and also switched from A to B if that action occurs. The procedure for the interface modules is the same. A strap added from E2 to EE on the top port will cause EE to appear at the top port only. If it is to appear also at the bottom port the additional strap must also be added there.

5 HARDWARE INSTALLATION

Remove po we r to t he she lf b y t urnin g of f the power supply or unplugg ing the power transforme r connected to the chassis.

If proceeding with an upgrade of a current installation it may be necessary to remove any cable wrap, clamps or cord form any existing cable brackets to allow room for installation of the conversion boards. Be careful not to damage cables or connectors in the process.

Working at the back of the equipment bay, install an FFM-01 or FFM-02 conversion board, as appropriate, into a slot at the right-most vacant position of the chassis. Conversion boards can only be installed in positions 1 through 16. Proceed as follows. While facing the back of the chassis, hold the conversion board in a vertical position with the 34-pin connectors towards yourself and the 25-pin connectors away for you. Place the three 25-pin connectors into the three 25-pin mating connectors on the chassis and press firmly into place. Tighten the two mounting screws per connector to assure a good connection.

The FF-01 or FF-02 conversi on board is meant t o convert the 17t h posit ion of t he RDC-01/P SC01 or RDC-02/PSC-02 PatchSwitch chassis to be used with the PSM-18 or PSM-19 interface modules. In addition, this module can also convert position 1 to 16 of the RDC-01/PSC-01 chassis to be used as interface module positions. If position 1-16 of a RDC-02/PSC-02 chassis must be converted to interface module positions, then the FF-02 must be used.

Bring the end of the DCE cable in from the side of the equipment rack and connect it to the bottom connector on the conversion board. Form the cable neatly away from the board along an equipment rack cable bracket towards the equipment rack upright. Be sure that the conversion board does not have any side pressure from the cable in any direction. Using cable straps or appropria te cord, fasten the cable to the cable bracket as app licable.

Bring the end of the “B” DTE cable in from the other side of the equipment rack and connect it to the middle connector on the conversion board. Form the cable neatly away from the connector sub-boa rd al ong an equipmen t r ack c able b rac ket towards t he equ ipme nt ra ck upri ght. Be sure that the conversion board does not have any side pressure from the cable in any direction. Using cable straps or appropriate cord fasten the cable to the cable bracket. Bring the end of the “A” DTE cable in from the the side of the equipment rack and connect it to the top connector on the conversion board. Form the cabl e neat ly a w ay fr om t he conv ersi on board along an equipment rack cable support bracket towards the equipment rack upright. Install additional conversion boards using the directions above. Work from the right side of the chassis towards the left (as see n from the rear). T his gives room to the left in w hich to work and makes for a much neater installation.

Carefully install the PatchSwitch V.35 module into the chassis making sure that the 96-pin DIN connector on the front of the unit engages the connector in the chassis. Tighten the hold-down screws on the front of the module

Plug the power transformer removed earlier back into its socket or turn on the power supply to re-establish power for the units.

3.2 Switch Module Interlocks

The A/B switch activates the A/B relays. The A/B relays complete the X.21 circuit between the DCE and either the DTE-A or DTE-B. The relays also switch in the interlock group. A and B status indicators show the DTE-A and DTE-B selection. Switch Interlocks prevent you from accidentally switching two modules to the same spare or equipment. The A/B interlock jumper Groups 1, 2, 3, and 4 allow for connection of each module to one of four different groups. The A/B interlock Group V allows each module on a chassis to be interlocked vertically with corresponding modules on any chassis connected with an interchassis interlock cable (catalog number 4WC-03).

3.3 Monitor, Patch, and Access Modules

These modules contain three front panel jacks for easy access to the X.21 data circuit, and rear connectors for attaching the module to the digital circuit. The rear connectors are provided to interface with the computers communications network. A portion of the rear connector is used to attach the X.21 circuit from the DTE (a computer or front end processor). The remainder of the rear connector is used to attach the circuit to the DCE (a modem).

In the normal mode (no patch cords inserted into the top or middle front jacks), the X.21 circuit has a through-path into and out of the Patch module. In the normal mode, the insertion of a patch cord connector into the top or middle front panel jack allows the entire circuit to be monitored with no interruption of the signals. In the patch mode, insertion of a patch cord connector into the bottom front panel jack breaks the circuit and permits monitoring of only the DCE portion of the data circuit.

Page 4-6

3.4 Status Indication Modules

The six X.21 circuit leads having LED indicators are: T, C, R, I, S, and B. When a monitored circuit lead is active (signal present), the associated LED indicator turns on only while the signal is present. The colors and signal definitions for the applicable Led Status indicators shown in Table 4-1.

Interlocking is used to protect the user from accidentally switching a common backup piece of equipment onto two or more di fferent data l in es. Thi s i s acc ompl ished by allowing only the fi rst 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.

Page 4-10

ADCP-50-304 • Issue 19 • June 1999 • Section 4: PatchSwitch X.21

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-p in i nt er cha ssi s i nt er loc k cable. W it h t hi s gr ouping, all modules having a jumper placed on group 1 make up one group, and all modules with a ju mp er on gr oup 2 make up the other group. Interchassis interlock cables must be installed between chassis. Each module interlock gr oup j umper bl ock may have no more than one jumper ins ta ll ed a t one time.

3. Vertical Interlock: The vertical in terl ock ju mper po siti on is la beled V. Placi ng a ju mper 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.

6.2 Alarm Jumper Installation

6.3 Alarm Time Delay Setting

Time delay values are fixed. The switch positions are time values ranging from none to 105.9 seconds nominal. The PSM-832002 Test/Status module contains two eight position rotary switches (A and B Alarm) on the front panel that can be set after the module is installed. All other modules contain one eight position rotary switch (B Alarm) on the front panel. This switch can be set afte r the module is installed. The A alarm time delay (cal l request) is set usi ng a 16 position rotary switch located on the PC board.

Time delay settings (8 position switch) are denoted on the front panel by varying length arcs around the rotary switch, the longer the arc – the greater the time delay. Time delay settings (16 position switch) are deno te d on t he switch by numbers and l et te rs . Set des ir ed t ime de la y bef ore installing module in the chassis. Time delay values are listed in Table 4-2 and Table 4-3.

ADCP-50-304 • Issue 19 • June 1999 • Section 5: Site Preparation

All PatchSwitch chassis are normally installed into existing standard 19-inch racks (or in 23inch racks with appropriate adapters). Each chassis occupies a rack space of 7 inches in height and 12 inches in depth.

Prior to installation, select the rack positions in the system where the chassis and other units of PatchSwitch equipment are to be located.

3 ENVIRONMENTAL CONSIDERATIONS

The allowable ambi ent temp eratu re range for shi pping or stor age is –40° F to +158° F (–40° C to + 70° C). For operation, the allowable ambient temperature range is from +32° F to +122° F (0° C to +50° C). The re lative humidity may vary from 10% to 80% in the rang e of +32° F to +122° F (0° C to +50° C) provided there is no condensation.

4 POWER REQUIREMENTS

Each PS chassis uses a power supply that requires a source of 110 Vac, 60Hz (or 220 Vac, 50 Hz) single phase commercial power. The PSW-000001 or PSW-000003 power supplies are stand-alone ac to dc converters with six-foot line power cords and six-foot chassis power cords. Convenience outlets must be within 12 feet of the chassis rear power connector.

This section contains the information necessary to install the PatchSwitch equipment.

1.1 PatchSwitch Chassis Installation (For PatchSwitch V.35 Installation, see Section 3)

Warning: To pr event electr ic al s hock, nev er i nstall PatchSwitch equipment in a wet location or during a lightning storm. When installing or modifying telephone lines, disconnect lines at the network interface before working with uninsulated lines or terminals

Carefully remove the PatchSwitch chassis from its shipping container and visually inspect the unit(s) for signs of damage.

When PatchSwitch equipment is shipped from the factory, each component and all

Note:

associated parts, hardware and accessories are properly packaged according to accepted practices for transporting via commercial common carrier. Evidence of actual or possible damage to the equipment, and/or missing parts, should immediately be reported to the commercial carrier or his agent and notify ADC Telecommunications, Inc.

The PatchSwitch equipment is normall y s hi pped with the modules ins ta lled i n the chassis. If th e modules are not contained in the chassis location slots when the shipment is received, perform the PatchSwi t ch Modul es Installation Procedure. When the c hassis is received with t he modules installed, perform the following procedure:

1. Mount the PS chassis in the selected rack space.

2. Secure the chassis to the rack with the appropriate standard hardware.

After each PS chassis is installed, perform the Chassis Power Supply Connection Procedure in this section of the manual.

ADCP-50-304 • Issue 19 • June 1999 • Section 6: Insta llatio n

1.2 PatchSwitch Module Installation Procedure

Modules may be instal led be fore o r aft er the ch assis is in st alled in the rack. If the modul es ar e to be installed after the chassis is installed, disconnect the power supply from the wall outlet before performing the following procedure.

Warni n g : A potential shock hazard exists whenever making adjustments inside any electrical device. Use extreme caution when approaching these areas. Ensure that the power to the rack and chassis is off. To avoid personal injury and/or equipment damage, the power to the chassis must remain off until all installation and connection procedures are completed.

1. Select the appropriate strapping options as determined by your application and described in Section 2, Section 3, and Section 4 of this manual.

2. Grasp the module by the front panel and insert it into the selected chassis position.

3. Slide the module into the guides until the unit is firmly seated.

4. Using a #3 Phillips-head screwdriver, secure the module to the chassis by tightening the two captive front panel screws.

5. Repeat the previous procedure for each module to be installed.

1.3 Blank Panel Installation

The blank panel is installed onto the chassis by positioning the blank panel over the empty chassis slot pos iti on and s ecu ring i t to the ch assis us ing th e tw o ca ptive f ront p anel Ph illi ps- head screws.

1.4 Chassis Power Supply Connection Procedure

Each PS chassis requires a separate power supply. The ac power supplies (PSW-000001 and PSW-000003) are equipped with six-foot line power cords and six-foot dc power cords.

The dc power cord contains five wires terminated with a female connector that plugs into a connector on the rear of the PS chassis.

The backplane connector and the dc power cord are “keyed” to prevent improper installation. See Figure 6-1 for power supply connector location.

These steps must be performed as indicated (first a then b). Performing step b first

Note:

will prevent the power supply from operating (no output voltage).

1. Connect the dc power supply cord female connector onto the chassis power supply male connector.

2. Connect power supply to input power source.

War n in g : To avoid possible personal and equipment damage, the power supply must not be installed until all installation procedures are completed.

3. Repeat steps 1 and 2 for each chassis and power supply.

1.5 Communications Network Interface Connections

The back of each PS chassis (see Figure 6-1) contains 50 standard D-sub 25 pin connect ors use d to interface PatchSwitch modules with a communications network. In the top row, beginning at the right in the illustration, the first 16 connectors (DTE A) are for connecting PatchSwitch modules to Computer ci rcui ts via c ustomer suppli ed ca bles. The 16 connec tors i n th e cente r row (DTE B) connect PatchSwitch modules to alternate Computer circuits via user supplied cables. The first 16 connectors in the bottom row (DCE), connect PatchSwitch modules to modem circuits via user supplied cables.

CONNECTORS

The top and bottom connectors of slot 17 are usually connected to test equipment so that a DTE or DCE may be connected to the test equipment via patch cord and the interface module.

With the PSR-06 RS-422/RS-232 Interface Converter Module installed in the PatchSwitch chassis (slot pos it ion 17), the top connec tor of slot position 17 provides the con nec ti on point for the RS-232 control device (modem, computer, CRT or RCU). Two 9-pin female type D-sub connectors on the backplane of the chassis provide for CM interface with another PS chassis. The bottom connector of slot position 17 is not used in this case. An eight position programming plug is provided on the PSR-06 Interface Converter printed circuit board for assigning the PatchSwitch assembly as a DTE or DCE device.

When system is directly connected to a terminal or computer the PSR-06 Interface Converter module should have the programming plug in the DCE position (see Figure 6-2). A straight through cable can then be used to connect the top connector of slot 17 to the terminal of computer. When system is connected to a modem, the PSR-06 Interface Converter module should have the programming plug in the DTE position. Make sure the programming plug is inserted into the correct DIP Socket, DTE or DCE as appropriate. There is also a two position Berg Strap used on the Berg Posts labeled DSR. In DTE mode, position the strap on the bottom and center post and in DCE mode position the strap on the top and center post. Refer to

Figure 6-2 for illustration of Berg strap and programming plug.

1.6 Control Module DIP Switch Settings

When PatchSwitch equipment is configured for serial remote control, the chassis address must be selected on each control module. For dc pulse control, the chassis address is ignored. Each CM contains a four - pos it ion DIP switch to identify its chassis address. Bi t p osi tions 1 through 4 on the DIP switch are set to an identifying address assigned to that chassis during the installation of the PS chassis system.

Some older control modules only allow addresses up to “07”. These can be identified by the digits –7702 at the end of the part number. Models with digits –7708 or –7709 are capable of addresses to “15”. Both can be intermixed in a system as long as the –7702 versions are assigned addresses of “07” or below.

A switch in the ON position represents a zero (0) bit, and conversely, a switch in the down position (not ON) represents a one (1) bit.

For example, when facing the component side of the CM circuit board, the address for the chassis nu mber 10 is set as shown in Figure 6-3.

2 CONTROL MODULE AUTOFALLBACK JUMPER INSTALLATION

When the autofallback option is selected, the proper jumper must be installed on the CM (Figure 6-4) before the module is installed in the PS chassis. Each CM has a group of four jumper select io ns l o cate d on th e si de of t h e c irc ui t b oa rd . Re fe r t o Figur e 6- 5 for an illustration of the autofallback jumpers.

If the jumper is installed in the “AUTO SW B” position, an alarm condition on any module within the PS chassis will cause switching to the “B” position from the “A” position. Similarly, if the jumper is in the “AUTO SW A” position, an alarm condition will cause a switch, to the “A” position from the “B” posit ion. If the automatic sw itching is not desire d, leave the jumper in the “STORE” position.

When installed, the autofallback selection does not override the CM software selection. That is, the software can change the switch position when the jumper strap is installed. However, if the alarm condition persists, the autofallback feature switches it back.

Caution: Do not jumper both the “AUTO SW A” and “AUTO SW B” at the same time. This type of installation causes the circuits to switch positions every time an alarm condition is sensed, and can cause “hunting” if both A and B alarm persists

It is recommended that systems configured for autofallback have all modules strapped for auto alarm reset.

4 PS MODULE JUMPER INSTALLATION

4.1 Interlock Jumper Installation

If an interlock option is desired for the system, the proper jumper must be connected in each A/ B Switching Module before it is installed into the chassis. Each A/B Switching Module has five interlock jumper positions. One jumper position for each of four interlock groups (labeled “1” through “4”) and one vertical interlock group (labeled “V” or “Store”). Refer to Figure 6-7 for the location of the jumpers on the module.

The three classes of interlock groups available are:

1. Global Interlock: Groups 1 and 2 are global and my be extended to all chassis at an installation, u si ng a n i nte rchassis interl ock cable. W i th this grouping, a ll modul es having a jumper on group 1 make up one group, and all modules wit h a j umper on group 2 make up the other group (providing interchassis cables are installed between chassis).

2. Horizontal Interlock: Groups 3 and 4 are horizontal and they include only modules in the individual chas sis. With thi s grou ping, al l modules i n a cha ssis ha ving a jumper on group 3 make up one group, and all modules having 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 cable.

3. Vertical Interlock: The vertical interlock jumper position is labeled with the letter “V”or the word “Store”. Installing a jumper on this position interlocks all modules in the same slot location in other chassis having a jumper on the same (V) position. (Providing an interchassis interlock cable is in place between the chassis). The interchassis interlock cable is a 20 position ribbon cable with a 20-pin connector for each chassis.

The interlock group jumper block must only have zero or one jumper installed. Never try to have more than one interlock jumpe r on any module.

4.2 Alarm Jumper Installation

The alarm jumper must be installed before the module is installed in the chassis. Each module with the alarming feature has eight alarm jumper positions. Refer to Figure 6-7 for the location of the jumpers. Select the signal whose absence triggers the alarm, and place the jumper in the appropriate position. Only one signal may be selected for alarm detection.

Page 6-8

4.3 Automatic Alarm Reset Jumper Installation

The automatic reset jumper must be installed before the module is installed in the chassis. Each module with the alarming feature has automatic reset and store jumper contacts in the lower right corner of the component side as shown in Figure 6-7. The alarm automatically reset s whe n the jumper is on the left set of contacts. The jumper may be stored (i.e., the alarm does not automatically reset) on the right set of contacts.

1 GENERAL

The PS equipment functions i n eit her patching or switchin g meth ods of ope rat ion. The patching operations includ e int rusiv e moni tor and interface whil e the switching operati ons are performed either locally or remotely.

2 PATCHING — IN-LINE ACCESS MODULES

In patching operations, patch cord connections are made through the front of the PS equipment modules. Those areas to be patched (communications network equipment) are connected to connectors on the rear of the PS equipment chassis. Refer to Figure 6-1 in Section 6 of this manual. All patch cords for use on this equipment ar e listed i n Table 1-2 in Section 1 of this manual.

2.1 Monitor Patching

Monitoring patching is performed by inserting a patch cord into the MONITOR jack of a PS equipment module. This provides a bridge connection to the RS-232/V.24 circuit, and this connection induces no interruption of the circuit. Now that the data circuit has been accessed, the other end of the patch cord can be inserted into the jack of an Interface Module that has test equipment attached to it. This monitor function can also be accomplished by patching a monitoring device (e.g., data line monitor) d irectly into the desired M ONITOR jack cir cuit.

2.2 Intrusive Patching

Intrusive patching is used to perform a restoral function on a failed component, to make a substitution of a different device, or to reroute a communications path. The patching function is activated by inserting a patch cord into either the COMPUTER or MODEM jacks of a PS equipment module. This action splits the circuit and routes the signals through the patch cord. The other end of the patch cord can then be inserted into another jack and in so doing, attach a different device. For example, it has been determined that a particular circuit has a bad modem. A patch cor d is th e n in s erte d int o that C OM P UTE R ja c k, a nd th e o th er e n d o f t h e pa tc h c or d is connected to the jack of a spare modem. This patching function has split the original circuit, rerouted the computer si gna ls t hr ough t he patch cord, and fin al ly co nnected the spare modem to the original data communications circuit.

Tandem operation of computers and/or modems is not recommended; and consequently, patch cords should not be used to connect a COMPUTER jack to another COMPUTER jack or MODEM jack to a MODEM jack.

3 PATCHING — OFF-LINE ACCESS MODULES

When the module is in the normal (A) state the upper port provides patch cord access to the upper “D” subminiature connector on the chassis rear panel, thus providing a “monitor” function. When the module is in the “B” or “sub" state, this port provides direct test access to the off-li ne device.

Page 7-2

The middle port functions in a similar manner for the middle connector on the chassis rear panel. When in the “B” state, monitor access; “A” state, test access to the off-line “B” device. The lower port provides intrusive access to the lower connector on the chassis backplane. Insertion of a patch cord in this port, regardless of switch status, breaks the circuit and connects the patchc ord to the co mmon (DCE) devi ce.

4 INTERFACE MODULE

When an Interf ace Mo dule is used, i t is co nnec ted b y inser ting a patch c ord into t he MONIT OR, COMPUTER, or MODEM jacks of a PS equipment module. This provides the access to these jacks to insert test equipment. The computer and modem circuits are split so their operation is affected. This is not true in the case of the monitor circuit. Test equipment, in this case, is connected to the chassis rear interface connector(s).

4.1 Test Module

When a test module is used, i t is co nnec ted in the communi catio ns l ine to access te st equi pment. This is first accomplished by inserting a patch cord between either the MONITOR, COMPUTER, or MODEM patch jacks of a PS equipment module and the test module patch jack. The test module pr o v ide s t wo RS-232/V.24 ports for con nec ti ng t est eq uip ment on t he r ea r of the module. Refer to Section 2 for a detailed functional description of the test modules.

ADCP-50-304 • Issue 19 • June 1999 • Section 7: Operation

5 SWITCHING

All PS module switching operations are performed in conjunction with the Control Module (CM). The Control Module is used to enable the switching of all the modules contained in the PS chassis. Modules in a PS chassis can be switched individually or all at one time (bank switching). The switches located on the individual modules and Control Module are listed in

Table 7-1.

A bank switching operation switches all of the A/B modules in a PS chassis to either the “A” position or “B” position. Both individual and banking operations may be done either locally or remotely.

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, the first module in this group will switch to th e B state. Data may be lost w hen more than one module is in the B state. 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 interlock group do not switch to the B state; consequently, the system maintains its integrity.

Allows operator to select eight dif ferent tim e delays for alarm operation.

6 CONTROL MODULE SWITCHING (LOCAL)

The switch function designators for the three momentary toggle switches located on the front panel of the control module are termed:

1. A/B MASTER

2. ENABLE

All Switch Modules

Alarm Capability

3. ALARM RESET

6.1 Interface Converter Module (PSR-06A)

The Interface Converter Module is used in conjunction with the Control Module to provide compatibility between a PatchSwitch Control Module and an RS-232 control device (modem computer, CRT or RCU). Only the first PS Chassis in a group needs to have a PSR-06A installed.

6.2 Single Channel Switching

To switch a PS module, the operator toggles the ENABLE switch to either off-center position while simultaneously toggling the channel's A/B switch (located on the PS module) in the desired direction. The channel switching operation does not require the operator to maintain the toggled position of either switch while waiting for the module switch function to occur. Once the toggling operation is performed, the circuitry senses the switch change and completes the module switching operation upon receiving an internal timing signal.

Page 7-4

6.3 Bank Switching

Bank switching is performed by the operator toggling the A/B MASTER switch (located on the Control Module) to either the A or B position and then toggling the ENABLE (directly below the A/B MASTER switch) switch (off-center position). This operation causes all of the PS chassis modules to switch to the channel (A or B) corresponding to the selection of the A/B MASTER switch. To avoid a slight delay in the switching operation, the A/B MASTER switch should be held in position (A or B) while toggling the ENABLE switch.

Bank switching starts with module 0 (slot l) and ends with PS chassis module 15 (slot 16). The individual module A/B switches are disabled while the A/B MASTER switch is toggled in either the A or B position.

6.4 Reset Alarms

To reset the module alarms, the operator toggles the ALARM RESE T switch (located on the Control Module) to either off-center position. If a constant alarm condition exists, the yellow LED indicators for each module sensing an alarm remain lit and the audible alarm remains activated, if enabled. I f a constant alarm condition no longer exists, toggling the ALARM RESET switch extinguishes all of the module alarm LEDs (yellow) and silences the audible alarm.

ADCP-50-304 • Issue 19 • June 1999 • Section 7: Operation

The alarm reset funct ion c lears all the al arm ci rcuit s. An in di vi dual mod ule alar m circu it may b e selectively reset by touching the two posts on the alarming module.

6.5 DC Pulse Control Switching

The PatchSwitch Control Module is capable of Bank switching the PS chassis modules which perform A/B switching by responding to dc voltage pulses received over the communications channel fro m a remote device. In order to e nable dc pulse control, the remote control jumper block must be set to the dc pulse control selection. Bank switching via (signal ground), +5V or –5V to –48V dc to the corresponding lead (s ee Table 2-2 for pin assignments) for a minimum of 250 msec and should be removed within 1 sec after application since all other switching functions are disabled during this time.

If a “switche d to” A dc voltag e level is applie d while a “swi tched to” B dc voltage

Note:

level is active, all modules will switch to the A position but will be restored to the B position after the “switched to” A signal is removed, provided the “switched to” B signal remains active.

As with front panel bank switching, all modules in the PS chassis will switch to the channel (A or B) corresponding to the dc voltage applied per Table 2-2.

Bank switching starts with module 0 (slot 1) and ends with PS module 15 (slot 16). The individual module A/B switches are disabled while the dc voltage is present.

Page 7-5

ADCP-50-304 • Issue 19 • June 1999 • Section 7: Opera tion

6.6 Remote Control Switching

The PatchSwitch Control Module is capable of controlling the PS chassis modules by responding to commands received on the communicat ions cha nnel fr om a remote cont rol device with the remote control jumper block in the RS-422 serial communications position. The CM also monitors the status of the PS chassis module A/B switches and alarm conditions and reports this information to the requesting remote control device via the same communications channel.

There are three types of devices which can remotely control a PatchSwitch system:

1. ADC Model SSN-100589 software running on a personal computer (PC)

2. User’s terminal or computer

3. PatchSwitch Remote Control Unit (RCU)

The PatchSwitch Remote Control Unit (RCU) is described in a separate publication. Refer to ADC Publication Number ADCP-50-302, PatchSwitch Remote Control Unit User Manual for operating instruct io ns.

The following information enables the user to communicate between a PatchSwitch Control Module (CM) and terminal or computer. This portion of the manual describes the ASCII commands exec ute d by a terminal for perfor ming the swi tc hi ng and moni to ring functions of the PS chassis modules.

6.7 Remote Control Commands

Commands are issued by the remote control device to: l) select the desired PS chassis; 2) perform the selected module(s) AIB switching operations; 3) request the status of the selected chassis PS modules; 4) reques t the sel ecte d CM softw a re re v ision level; 5) en able/ disabl e alarm reporting; 6) clear all alarm reporting conditions; and 7) de-select PS chassis.

6.8 Command Conventions

Remote control devices must issue commands compatible to the CM software. When entering commands on an ASCII keyboard, observe the following conventions.

String Entries.

string must contain a Carriage Return (CR) and a Line Feed (LF) character for a command terminator. The CM command string buffer can hold up to forty (40) characters. This number includes the CR/LF characters, terminating the command string.

All keyboard commands are entered in ASCII character strings. Each command

Backspace (con trol- H) and del ete- line (c ontrol -U) ch aract ers are re cogniz ed b y the CM soft war e and are valid in the command string. There is no distinction between upper and lower case alpha characters as the CM software converts all lower case alpha ch aracters to upper case (caps).

Parameter Entries

parameter separator may be any non-digit (0-9) character. There are no restrictions on the number of blank character spaces or zero characters preceding (or leading) the parameter, except for the 40 character buffer limit.

Page 7-6

. Command parameters are usually separated by commas, although a

Non-digit and non- bla nk characters are r ecog n iz ed by the CM software as parameter s epar at o r s. Therefore, two such consecutive characters (non-digit and nonblank) are recognized as a null parameter. Each null parameter is replaced with a default value assigned by the CM software. If the null parameter does not have a legal default value assigned to it, the CM issues an error message to the remote control d evice.

6.9 Command Flags

Two flags are used to inform the CM when to execute an incoming command. The two command flags are:

1. Execute Flag

2. Echo Flag

Note:

SPK, SC, UNT) and the GO command. Command flags are applicable to the commands (AB, IN, UP, REV, AL) issued to request switching, status or reset (clear alarms).

ADCP-50-304 • Issue 19 • June 1999 • Section 7: Operation

These flags DO NOT apply to select/ de-select PS chassis commands (TLK, CRT,

Execute Flag

. Any valid command string containing a pound sign (#) character causes the CM to execute the command immediately. The “#” character may be located anywhere within the command string and may appear as a parameter separator.

Echo Flag.

Any command character string containing the dollar sign ($) character causes the CM to re-transmit the command string to the remote control device. This permits the operator to review and verify the parameter selections previously entered and transmitted to the selected PS chassis. If the parameters are valid, but incorrectly entered, the operator should re-enter the command string.

When a command string contains “$” characters, the CM software saves the command. The command remains stored in the CM until a GO command is recognized. When a GO command is recognized, the software attempts to execute the command string received (currently stored) just prior to GO command. If the command is invalid, an error message is returned to the sending device. If the character string is a valid command, the actions defined by the command are executed. After the command is executed, the command is erased by the system software. Any subsequent GO commands are ignored by the CM until the next command string is received. The “$” character may be located anywhere within the command string and may appear as a p arameter separator.

6.10 Command Interpretation

All valid commands must appear as the first characters in the string. Characters appearing after the command (as well as any parameters) do not affect the CM command interpretation. For example, the system would correctly interpret the GO command from the following character strings:

GO-JUMP/IN THE LAKE GOPHER STATE

Page 7-7

ADCP-50-304 • Issue 19 • June 1999 • Section 7: Opera tion

In the next example, the system would not inter pret the GO command from th e strings:

bGO (b meaning blank) GGO

As previously stated, commands may be entered in either upper or lower case alpha characters. Case has no effect on the CM interpretation.

6.11 Command Responses

Whenever an activated (selected) PS chassis receives a command string, the CM responds by sending one of the following character strings to the terminal (remote control device):

RDYxx MSGxx ERRxx, (error code)

The characters “xx” identify the chassis (CM) originating the response. The identification characters “xx” have a value in the range of 00-07.

If the last command did not execute properly, or if the command parameters (or syntax) were invalid, the CM returns an error message containing an error code. The error codes are defined at the end of this section.

If a change in the PS chass is occurred after t he CM transmitted the last st atus information to t h e remote control device, the CM responds with MSGxx.

If a temporary status change occurred and the status of the chassis returned to the

Note:

status last transmitted, the software does not indicate a change. That is, the CM does not respond with MSGxx.

If neither an error condition or status change occurred since the chassis responded to the last command, the CM responds with RDYxx.

6.12 Command Descriptions

The CM responds to ASCII character commands received on the connected communications data channel. These commands provide the user with the following functional operations:

1. Select PS Chassis

2. Request Software Revision Level

3. Request Status

4. Reset Alarm Status

5. Enable/Disable Alarm Status Reporting (valid only with CRTxx)

6. Request Switching

7. De-select the PS Ch assis

Page 7-8

6.13 Select PS Chassis Command

The remote control device sele ct s a PS ch assis by issuin g an activation command cont aining the chassis' identification number. Chassis' identificat i on number s ar e det er mi ne d b y t he settings on the DIP switch located on the chassis CM. Refer to Section 6 for a description of the DIP switch settings.

There are four different select commands acceptable by the CM. The first three select commands identify the type of remote control device connected to the data communications channel. The fourth command selects multiple chassis simultaneously. The four different select commands are defined and used as follows:

TLKxx Command (talk) issued by a terminal user to select PS chassis xx

The identification "xx" must be characters in the range 00- l5.

Note:

SPKxx Command (talk) issued by the PatchSwitch Remote Control Unit to select PS chassis

“xx”.

CRTxx Command (talk) issued by the SwitchMate Intelligent Controller to select PS chassis

“xx”.

ADCP-50-304 • Issue 19 • June 1999 • Section 7: Operation

SC, xx, xx, xx xxCommand (Super Chassis) issued by a terminal user to select multiple PS

If the chassis identification (xx) number in the “TLK”, “CRT” or “SPK” command on a CM matches the DIP switch settings, the identified chassis is selected. If the chassis identification number in the command does not match the DIP switch settings on a CM, the chassis is deselected. When setting the CM DIP switches, the user must ensure that no two CMs have the same identifier (address). Refer to the Installation Section, Section 6, for the DIP switch selection procedure.

When the Super Chassis (SC) command is used to select multiple chassis, each selected chassis identification (xx) number (parameter) is entered in a string using commas for parameter separators. All other chassis in the system are de-selected.

6.14 GO Command

The GO command requests the selected PS Chassis to execute the command string that immediately preceded the GO command. Normall y, the GO command is issued by the user after the remote control device receives a RDYxx response. Once the pending command is executed, subsequent GO commands received by the CM software are disregarded. The GO command string is terminated with the CR/LF characters.

chassis simultaneously. Up to sixteen chassis may be selected (e.g., 00, 01, 02, 05, 07 or “all” for sixteen).

Page 7-9

ADCP-50-304 • Issue 19 • June 1999 • Section 7: Opera tion

6.15 Request Software Revision Level (REV) Command)

The REV command requests the CM to transmit the software revision level. The REV command string must co ntain a command fl ag (# or $) prior t o the line feed ( LF) ch ar act er. If an echo flag occurs in the command string, the user must issue a GO command before the PS chassis will return the revision level message. When the remote control device sends the “REV#CRLF” command string, the selected PS chassis respond with the following message:

Patch Remote Control Module Revision x.y Copyright ADC Telecommunications, Inc.

The characters x.y above represent the revision level of the software.

6.16 Request Status (UPdate Command)

The UPdate command requests t he CM to tr ansmit the status of al l t he modules contained in t he selected PS chassis. The UPdate command string must contain a command flag (# or $) prior to the string terminating CR/LF characters. If an echo flag ($) occurs in the UPdate command string, the user must issue a GO command before the PS chassis status is transmitted.

6.17 Status Responses

Status is transmitted from the CM to the requesting remote control device in one of three formats. The format transmitted depends upon the type of select command used when the chassis is originally selected. If the “TLKxx” command activated the PS chassis, the status response formats outlined in Table 7-2 through Tab le 7- 5 are returned. The status response format associated with the "SPKxx" command is outlined in Table 7-6. The status response format associated with the “CRTxx” command is described in the SwitchMate Switch Cluster Controller Software Specification, ADCP-50-595.

6.18 TLKxx Format

When using the TLKXX format, control is by means of menu selections, module position entries, and control keys. Each of these are described in the following paragraphs.

6.18.1 Menu Selection

When using the TLKxx format, most data entries are through menu selections. All menus are described later in this section as part of the operating procedures.

The > symbol shown with each menu is the “invitation to type”, indicating that system is waiting for operator input. Default key-ins are shown in parenthesis. A dash in parenthesis indicates that there is no default selection for the menu.

(–) > — To enter a selection, type selection number and press RETURN. (3) > — The number in parenthesis indi cat es the default se le cti on. To ente r a differen t s el ect ion,

type desired selection number and press RETURN. If number in parenthesis is the number of the desired menu item, just press RETURN.

6.20 SPKxx Format

When a remote control device selects a PS chassis by issuing a “SPKxx” command, and then requests status by issuing a “UP#” command, the CM responds with the condensed status format. The condensed status format is a string of eight hexadecimal digits representing the switch positions and alarm conditions for all 16 module slots contained in the selected PS chassis. The “SPKxx” command is used by the RCU.

Each digit displayed is a hexadecimal code representing the switch position or alarm condition for four PS modules. As shown in the example of Tab l e 7 -6 , the first four hexadecimal digits “56A3” define the switch positions for all l6 modules. The first hexadecimal digit “5” is decoded to it’s bin ary equiva lent which is “0101”. These four binary digits (bi ts ) a re ass ign ed t o module addresses 15 (most significant) through 12. The response is read from left to right with Module l5 assigned to the most significant bit in the hexadecimal code. A “0” bit indicates the module is in the ‘A’ switch position and conversely, a “1” bit indicates the module is in the “B” switch position.

The second, third and fourth hexadecimal digits (616, A16 and 316) are decoded to their binary equivalents which are “0110”, “1010”, and “00l1”, respectively. These 12 bits are assigned to module addresses 11 through 0 (least significant). In this example (56A3)16, modules 15, 13, 11, 8 6, 4, 3, and 2 are in the “A” switch position and modules 14, l2, 10, 9, 7, 5, l, and 0 are in the “B” switch position.

The alarm st atus for the same l6 PS modules is displayed in the last four hexadec imal digits “10l0”. The alarm status code is read in the same manner as the switch status code. The fifth hexadecimal digit “1” is decoded to it's binary equivalent which is “000l”. These four binary digits (bits) are assigned to module addresses 15 (most significant) through 12. A “0” bit indicates a no alarm condition for the module and conversely, a “l” bit indicates the module detected an alarm.

The second, third and fourth hexadecimal digits (0

, 116 and 016) are decoded to their binary

equivalents which are “0000”, “000l”, and “0000”, respectively. These twelve bits are assigned to module addresses l l through 0 (least significant). Therefore, in this example (1010)

modules l2 and 4 indicate an alarm con dit ion is detected and the remaining mo dul es in dic at e no alarm is de tected.

Tab le 7- 6 shows an example of the condensed status format received by a terminal when a

request for status is issued for PS Chassis 0l. This format is primarily used by the Control Module to transmit status to the ADC Remote Control Unit (PSR-03) indicator display.

6.21 Reset Alarm Status (IN Command)

The IN (Initialize) command requests the CM to reset the alarm status in all the modules contained in the selected PS chassis. The IN command string must contain a command flag (# or $) prior to the string terminating characters. If an echo flag occurs in the IN command string, the user must issue a GO command before the selected PS chassis resets the alarm reporting status in the a ssociated modules. W hen the term inal sends t he “IN#CRL F” command , the CM software resets all modules that are indicating an alarm condition.

Modules l4 and l2 in “B” switch position.

= 01102 = Modules 11 and 8 in “A” switch position.

Modules l0 and 9 in “B” switch position.

= 10102 = Modules 6 and 4 in “A” switch position.

Modules 7 and 5 in “B” switch position.

= 00112 = Modules 3 and 2 in “A” switch position.

Modules l and 0 in “B” switch position.

= 00012 = Modules 15, l4, and 13 no alarm detected.

Module l2 in alarm.

= 00002 = Modules 11, l0, 9, and 8 no alarm detected. = 00012 = Modules 7, 6, and 5 no alarm detected.

Module 4 in alarm.

= 00002 = Modules 3, 2, 1, and 0 no alarm detected.

6.22 Enable/Disable Alarm Status Reporting (AL Command)

The AL (ALarm) command enables or disables the alarm status reporting for any one or all modules in the selected PS chassis. This command enables or disables the appearance of an alarm condition in t he st atus r espons e fro m the CM. Actual ly, the reporting PS chassis may have an alarm conditio n, b u t the softw a re ign ores t hi s condi tion when t he di sable functi on is in ef f ect . The AL command is a software function only, and does not change the state of the hardware when executed.

The AL command must contain a string of parameters for defining the action (enable or disable), the type of c ir cui t c ard , the slot number where the act io n is to start and the slot number where the action is to end. The AL command string parameters must be in valid syntax and contain a command flag (# or $) prior to the string terminating characters. If an echo flag ($) occurs in the AL command string, the user must issue a GO command before the PS chassis enables or disables alarm status reporting for the selected module slots. If an execute flag (#) is contained in the AL command string, the CM executes the AL command string immediately when it is received.

Page 7-19

ADCP-50-304 • Issue 19 • June 1999 • Section 7: Opera tion

The format for the AL command string parameters is as follows:

AL, <action>, <cardtype> , <startslot> , <endslot>,

The CM issues an error message if any parame ter value is not wit hin the specified range of values. An error message occurs if the startslot value is greater than the endslot value.

<flag>CRLF

Note:

Alarm conditions are always reported to a Remote Control Unit (PSR-03) and

terminal.

6.23 Request Switching (AB Command)

The AB command switches one or more modules contained in the selected PS chassis. This command permits the operator to assign an alternate path for circuit operation. The AB command also establishes the current position of the A/B switch for all selected modules.

The AB command contains a str ing of pa rame ters that define the modul e slot( s) sel ec ted and t he switch position (acti on) for the module(s). The AB command string parameters must be in valid syntax and contain a command flag ( # or $) prio r to the string terminatin g char ac ter s. I f an ec ho

flag ($) occurs in the AB command string, the user must issue a GO command to perform the switching operations. If an execute flag (#) occurs in the AB command string, the CM executes the AB command string imme diately when it is received.

Caution: When using Autofallback, the operator’s switching commands may be negated. That is, modules in alarm state switch to the side specified by the jumper (A or B). This switching operation is performed regardless of the operator’s commands

6.24 Request Super Chassis Command (SC Command)

The SC (Super Chassis) command is a quick-switch feature used by the remote control device (terminal) to simultaneously select multiple chassis. This command is normally used in conjunction with a subsequent AB or AL command to perform AB switching and/or to enable alarm reporting after the chassis are selected. All chassis selected by the SC command, have their status response “silenced”. That is, status is not provided by any chassis selected as a result of the SC command. All chassis specified for selection in the command become activated immediately upon receiving the SC command.

Only the AB, AL and IN commands are valid commands associated with the SC

Note:

command.

For example, when the command “SC,00,0l,02,04” is issued, chassis numbers (chassis identifiers) 00, 01, 02 and 04 are selected. Similarly, if the command “SC,ALL ” is issued, all chassis in the system are immediately selected and all status responses are silenced. Each chassis specified by the SC command operates independently from all other chassis in the system.

All chassis in the system not selected by the SC command are de-selected.

Ta b le 7 - 9 describes the syntax for the command string parameters and defines the operations

performed by the SC command. Examples of the valid subsequent commands AB and AL are also shown.

6.26 Error Codes

The CM responds with an error message when the remote control device issues a command containing a parameter syntax error or when the CM cannot prop-erly execute the last switch command received. Error code ERR00,??? will be received when an incorrect syntax has been entered. Check the command and try again. The error message has the format:

ERRxx,nn,yyyy

Where: ERR — indicates an error message.

The error codes are: *15,l0yy AB card yy failed to switch, where yy is in the range 00-15.

* This error will occur if a bank switch command is sent to a switch chassis which is not fully loaded with l6 switch modules.

xx = the PS chassis identification name in the range 00-07. nn = the type of error (error code). yyyy = the specific error.

6.27 Testing The Communications Line

Once a chassis is activated by a terminal, the user may test the quality of the communications line transmission by sending a message (test data) or random character string to the selected chassis. The test data string must include an echo command flag before sending the LF termination character. All character strings entered containing a “$” sign character and terminated with a LF, are returned to the issuing terminal. Because the selected PS chassis does not act upon data received until a GO command is recognized, no error is indicated. If a GO command is executed and the data previously sent to the chassis is invalid, the CM responds with an error message.

If the test data contains a “#” character, an error message is immediately returned to the originating remote control device.
