Reference Manual Chapter 2: Overview

Chapter 2: Overview

The Teltone®SLSS has been designed to consolidate telephone lines at electrical utility substations. It enables utilities having only one telephone line or those using multiple telephone lines for data transfers to save costs through line sharing. The SLSS also increases line efficiency by allowing devices, such as telephones, modems connected to fault locating relays, meters, etc., and fax machines to shareaphonelinein a substation. It can work with a Teltone Polling Controllerasasystem(U.S. Patent No. 5,241,587)orit canoperate asa standalone unit to give you a flexible, cost-effective way to eliminate extra substation telephone lines and route calls. Figure1 illustratesa typical application,in whicha singletelephoneline isshared by fourdevices.The Polling Controllerisadded to your existinghardware atthe data retrieval location.

The SLSS offers many benefits, some of which include its ability to:

• Share a single substation telephone line between up to eight devices.

• Eliminate expensive telephone line installation and monthly charges for

briefly used modem lines.

• Ensure correct call routing by using a Polling Controller.

• Enhance worker safety by giving priority to telephone users.

• Hide substation modems from unauthorized access.

• Obtain high reliability and availability with a unit providing C37.90 SWC

protection to attached devices and powered from 42-150 VDC batteries (“A” and “B” models only) or 90-150VAC (“D” model only) or 90-220VAC (“E” model only).

❑ Provide power to the SLSS and check that all LEDs light momentarily. The

Status LED will blink indicating the SLSS is idle. If power is lost to the SLSS, a direct path between the C.O. Line port and Port 1 is maintained.)

❑ Run the wiring for the terminal block to the left of the unit, through the tie

block. Secure the wires using the “zip” ties.

❑ Replace the yellow terminal block cover. ❑ Run the CO Line and all port cabling to the right, through the tie block.

Install Polling Controller (optional)

If you are using the SLSS with the Polling Controller, follow these steps. These instructions are repeated in the Po lling Controller Reference Manual, 40-400-00013.These stepsrequireapersonatboth thePolling ControllerandSLSS locations.

❑ Plug the incoming Central Office telephone line into the Telco Line port on

the back panel of the Polling Controller. (The incoming line comes from the telephone RJ-11/wall jack.)

❑ Connect another standard modular telephone cord from the modem to the

Modem port on the back of the Polling Controller. (The cords are available as an ordering option.)

❑ Connect a standard RS-232 cable from the modem to the computer (PC,

mainframe, or workstation) used to control polling.

❑ Connect the PS-24DC-01 power transformer cord to the jack labeled: Class

2 Input Power Pack, on the rear of the Polling Controller. Plug the power transformer into a 120 VAC outlet.

❑ If you are using multiple Polling Controllers, see the Installing Multiple

Units in Carrier instructions in the Polling Controller Reference Manual

(40-400-00013).

❑ The power LED on the back panel should be flashing. If not, check that the

power is securely connected. (If the LED does not light, check the power connection and fuse. If the LED is on bright, but does not flash, see the Troubleshooting instructions in the appendix.)

❑ Place a call to the telephone connected to Port 1 on the SLSS. The call

should be answered by the SLSS on the first ring and the Port 1 telephone should ring after four seconds. Answer the phone, then hang up.

❑ The system is ready to go to work. To call one of the ports on the SLSS, dial

the SLSS telephone number and add a routing code to the end.

❑ Test that calls are routed properly by plugging a device into Port 3 on the

SLSS, then call the SLSS and enter the routing code for Port 3. Check that Port 3 rings and that the LED flashes on and off.

❑ Forexample: CallPort 3on theSLSS bydialing 1-206-555-1212∗03from aphone

plugged into the Polling Controller.

❑ Routing codes ∗01-∗08 sends calls to Ports 1-8 as follows: ∗01 routes calls to

Port 1, ∗02 to Port 2, and ∗03 to Port 3, etc.

❑ (Optional.) If you will not be using the default settings, see Programming

Tips in Chapter 4. To program the Polling Controller, refer to the Polling

Controller Reference Manual (40-400-00013).

Reference Manual Chapter 3: Installation

Setup Standalone Operation

Follow the steps below to setup the SLSS to work without a Polling Controller.

Note:

the Polling Controller must be re-programmed with transfer codes which match those of the SLSS.

Remember that if the SLSS will ever work with a Polling Controller,

❑ Disconnect the incoming CO line from the SLSS. ❑ Connect a DTMF telephone to Port 2 of the SLSS. ❑ Pick up the phone and enter # # within 15 seconds. ❑ When you hear the three-beep confirmation tone, enter ∗00#∗02# to

activate the Standalone defaults. Listen for the three-beep confirmation.

❑ Hang up the telephone and reconnect the incoming CO line to the SLSS. ❑ The power LED on the front panel should be flashing. If it is not, check that

the power is securely connected. (If the LED does not light, check the power connection and fuse. If the LED is on bright, but does not flash, call Technical Support.)

❑ Call the telephone connected to Port 1. The call should be answered by the

SLSS on the first ring and the Port 1 telephone should ring after four seconds.

❑ Answer the phone, then hang up. ❑ Now you can call a port on the SLSS by adding the Standalone transfer

codes to the end of the SLSS phone number. (Standalone transfer codes 11-88 access Ports 1-8 as follows: 11 accesses Port 1, 22 accesses Port 2, and 33 accesses Port 3, etc.) See Chapter 4: Changing Transfer Codes to program new codes.

❑ For example, to call Port 2, dial the SLSS number. Enter 22 after the first ring

(within 4 seconds).

-or-

❑ If you will not be using the Standalone Defaults, review the Programming

Tips in Chapter 4 and follow the Standalone SLSS Programming, also in Chapter 4.

❑ (Optional) To call through a modem, remember to give the receiving

modem time to answer by adding pause time (,,,,) between the SLSS telephone number and the transfer code.

If the modem does not answer properly, add or remove commas. If the call defaults to Port 1, the pause is too long and you should remove one or more commas. When adding or removing commas, do so one at a time.

40-400-00031, Rev. A Page 9

Page 18

Substation Line Sharing Switch

The number of commas you will add depends on the time required for the network to process your call and for the SLSS to answer the call.

❑ For example, to send a call to Port 3, dial: 1-206-555-1212,,,,33

Note:

The guesswork involved in determining the correct number of pauses

is why many users decide to use the Teltone Polling Controller.

Tips before following the Setup for Local, Remote or Standalone

Programming instructions.

Chapter 4: Programming

Programming Tips

You can adjust or program many of features in the SLSS. All of the options and commands are listed in Table 2, later in this chapter. The SLSS is programmed using a touchtone telephone, either locally, without disconnecting the CO Line, or remotely from the Polling Controller.

Passwords

Always enter # after entering a password. If an invalid password is entered, you will not hear three beeps and should hang up and wait for 30 seconds before trying again. If three consecutive invalid attempts are made, the SLSS will lock out all further access for 1 hour. (M-395-B, D, E models only: If secure relay access is enabled, the SLSS will allow 5 consecutive invalid attempts.)

Note:

this password.

Remote Programming

Remote Programming must be enabled through Local Programming before you can access the SLSS remotely. When you have finished programming remotely, exit by hanging up the telephone. You cannot disable the Remote Programming feature while in Remote Programming.

ConfirmationTone

When a command has been entered successfully, you will hear a three-beep confirmation tone after entering the last #.

ErrorTone

When a command has been entered incorrectly, you will hear a single-beep error tone after entering the last #.

Enable/Disable

With functions that are either enabled or disabled, such as fax routing, an entry of 0 in the data field disables a feature; 1 enables it.

The password used to access the Auxiliary Relay must be different from

Cancel Command

To canceltheentire command, enter ∗in a command field. To cancel a command, back to, but excluding the #, enter ∗ in a data field. To abort the entire command, enter ∗∗ in a data field. If no data is entered in a field, that field is either cleared or set to zero.

40-400-00031, Rev. A Page 11

Page 20

Substation Line Sharing Switch

Transfer Codes

When assigning transfercodesfor remote programming or for ports (commands

∗07#n#x# and ∗12#y#n#x#), follow these rules:

• Transfer codes must have the same number of digits, be no more than four digits

long, be unique (i.e., all codes must be different), and can use any of the 16 DTMF digits.

• If you do not use the defaults, all codes must be programmed in both the

SLSS and Polling Controller.

Entering Programming Commands

You canenter the commands in any order. If you will not use aparticular feature, skip to the next and continue programming.

Threebeeps tell youthat the SLSSreceivedthe command.One long tonetellsyou that the command was incorrect and must be entered again. If you make a mistake, simply re-enter the command correctly.

To enter a command, replace “n,” “x,” and “y” with the desired values.

❑ For example, to change the number of rings before disconnect from 12 to 10,

enter

∗01#10#.

❑ For example, to change the password to 1234, enter ∗03#1234#1234#. ❑ For example, to change the Port 2 transfer code to 8802, enter *12#2#4#8802#

Setup for Remote Programming with a Polling Controller

Note:

Emergency Priority. If one of these priority modes is enabled, Port 1 will be able to interrupt programming.

The SLSS will exit programming mode and disconnect if 60 seconds elapse without entry of any digits.

The factory default for Remote Programming is enabled. If you have disabled Remote Programming, it must be enabled before you can program.

You can access the SLSS for programming from the Polling Controller using a special transfer code. You must enter a password after entering the Remote Programming Transfer Code. The transfer code instructs the SLSS to answer without ringing any of the device ports. Proceed as follows:

Programming may be interrupted if you have enabled Total or

❑ Disconnect the Polling Controller from the host modem. ❑ Plug a DTMF telephone into the Modem port on the Polling Controller.

❑ Dial the number of the SLSS, adding the #7 routing code to the end of the

number. (This is the Polling Controller default for the Remote Programming Transfer code.)

❑ When the Polling Controller connects to the switch (you will hear three

beeps and the LED flashes), enter the password within 30 seconds: 8358663# (The default is “Teltone”.)

If an invalid password is entered, there will be no acknowledgment of any kind. Hang up and wait for 30 seconds before trying again.

❑ When you hear the three-beep confirmation tone, begin programming or

follow the example below. (If you decide to program, please review the example first.)

Reference Manual Chapter 4: Programming

Changing Transfer Codes

Table 3 lists the routing codes that the calling modem sends to the Polling Controller. The routing codes are receivedby the Polling Controller, which sends a transfer code to the SLSS, telling it which port should get the call.

The default transfer codes are unpublished to protect the security of those who choose not to program different values. Some people change the transfer codes to increase security or to enable the SLSS to work with and without a Polling Controller.

❑ Follow the Access Local Programming or Access Remote Programming

instructions earlier in this chapter.

❑ To change the unpublished factory defaults for the transfer codes, enter

new transfer codes in the middle column of Table 3.

❑ Program the new values using command: ∗12#y#n#x# (Transfer Codes for

SLSS ports)

❑ Example: Followtheappropriate steps to access the SLSSforprogramming with

or without the Polling Controller and either remotely or locally.

❑ Example: To change the transfer code for Port 3 to ∗13, enter: ∗12#3#3#∗13#

and listen for three beeps.

Note:

Figure 5 Polling Controller and SLSS Operation

Basic Operation

When installed and working as a system, the SLSS and Polling Controller communicate acrossthe private telephone network to set up and disconnect calls, as well as to determine priorities among devices and types of calls. For example: outgoing emergency calls from the substation take priority over polling calls.

The SLSS answersincomingcalls, determines which port should getthecall, and routes the call accordingly.

If a transfer code is received from a Polling Controller, the SLSS routes the call to the requesteddevice,such as a polled modem. If no transfer code is received, the call is routed to the default port (Port 1 is the factory default) which is usually connectedto atelephone. Ifno defaultport isdefined,callswithouttransfer codes are disconnected.

You can selectavariety of SLSS operations by programming the unit remotelyor locally (on-site) using a touchtone telephone.

TheSLSS canbeused withorwithoutaPolling Controller. However, Teltonehighly recommends that the SLSS be used with a Polling Controller. When used without a PollingController,thecallermustbesurethe SLSSanswers thecallbeforetransfer codes are sent to route the call.

An advantage of using the Polling Controller is that the user does not need to generate thepause time (,,,,) inthedial string betweenthetelephone number and routing code to accommodate network delays. (The pause time is a series of commaswhich givestheSLSS timetoanswerthecall beforeitreceivesthetransfer code.) In addition, the Polling Controller will hang-up polling calls at the originating end when a priority call starts at the SLSS.

Typical Call Sequence

When thePolling Controller andSLSS are workingtogetheras asystem,a typical polling call from a host computer would progress as described below:

The host modem dials the SLSS to access a modem on Port 3 of the remote SLSS, by dialing: 1-206-555-1212∗03

The Public Switched Telephone Network (PSTN) processes the call and rings the remote SLSS.

As soon as the Polling Controller recognizes ∗03 as a valid routing code, it puts the calling modem on hold. Then it starts sending a translation of the routing codes (one to four digits). This translation or transfer code, is sent at regular intervals to the SLSS so that when the SLSS answers the call, the transfer code is received within a second or two. The transfer code is sent until the SLSS acknowledges receipt or until the calling modem terminates the call.

The SLSS answers the call at the end of the first ring and waits for a transfer code (you program the length of time, the Delay Before Routing, that the SLSS waits for the code, the default is four seconds). If the SLSS does not receive a transfer code, it rings the default port; the factory default for this is Port 1.

When the SLSS recognizes the valid transfer code for Port 3, it rings Port 3 and sends an acknowledgment tone to the Polling Controller.

When the Polling Controller recognizes the acknowledgment tone, it removes the hold so that the calling modem will be listening when the receiving modem attached to Port 3 answers the data call.

Note:

A modem answer tone is used as an acknowledgment tone so that a Polling Controller can be used to dial remote modems when no SLSS is installed.

At this point, the Polling Controller and SLSS have established a path for the data call, enabling the calling and answering modems to communicate.

Reference Manual Chapter 5: Polling Controller and SLSS Operation/Features

Operational Details

Transfer Codes

When the Polling Controller receives routing code, it translates it into a transfer code and sends the transfer code to the SLSS. These codes determine the SLSS port to which a call is routed.

The SLSS arrives from the factory with unpublished transfer codes which you can change. (Please refer to Tables 2 and 3.) Each SLSS port must have a transfer code of one to four digits in length.

If you are using the SLSS as a standalone unit, the transfer codes can be sent without a Polling Controller from a DTMF telephone or modem. (Please see Standalone SLSS Operation for more detail.)

Calling Party Supervision

The U.S.telephone network typicallyuses Calling PartySupervision. This means that even though the called party hangs up, she/he may be reconnected to the calling partywhen her/his phone is takenoff-hook again. The callingparty must hang up in order for the called party to be fully disconnected to initiate a new call. The telephone network will time out and automatically disconnect the call within 5 - 20 seconds, depending on network design. This will allow the called party to get dial tone when she/he goes off-hook again.

To circumvent this problem, when the SLSS senses a priority interrupt it immediately signalsthe Polling Controller to disconnecttheoriginal polling call. This ensures that the user initiating the priority will be able to complete the priority call.

If for any reason the interrupted call cannot be terminated within 5 seconds, a busy tone is returned to the priority caller. The caller should then hang up for a few seconds before trying the call again.

Outgoing Calls from the SLSS

The SLSS allows DTMF and rotary dialing on outgoing calls.

Outgoing Telephone Calls—SLSS Idle

When the SLSS is idle and a phone goes off-hook, the port is switched to the Central Office line and the caller hears dial tone. When the phone goes on-hook, the SLSS is idle again. (When the SLSS is idle, the ports connect to a local battery feed.)

Outgoing TelephoneCalls—SLSS Active

InTotalPriorityMode a higher-priorityportis given accessto the linewhenever it goes off-hook.

40-400-00031, Rev. A Page 27

Page 36

Substation Line Sharing Switch

If the SLSS receives no response from the Polling Controller after trying to disconnect threetimes, the SLSS disconnects andthe calling party hearsdialtone from the Central Office.

In Emergency Priority Mode, the telephone at Port 1 receives dial tone and the caller can dial one of the programmed emergency numbers. (If a dialed phone number does not match the listed numbers, the caller hears a busy signal.) If the dialed number matches a programmed emergency phone number, the line is freed for the telephone. The SLSS then dials the number and connects the telephone totheCentral Office line. The callermust enter the emergencynumber within 30 seconds or Port 1 will go into Privacy Timeout. (See page 30.)

Whenever Port 1 goes off-hookin Emergency Priority Mode, the caller hearsdial tone sent by the SLSS, not by the network. The tone can be standard or stuttered. Usingthe stuttereddial tonetellsthe callerthat theyare dialingthroughtheSLSS, not directly through the network.

If you have programmed an Access Code, the SLSS will connect to the Central Officelinewhenthetelephone calleronPort 1entersthe accesscode.Afterhe/she hears dial tone, any number can be dialed.

Caution:

If an SLSS port is receiving an incoming fax when you go off-hook in either Total Priority Mode or Emergency Priority Mode, the SLSS will be unable to obtain network dial tone until the sending fax disconnects or until the PSTN times out (usually within 10-15 seconds).

In No Priority Mode, the modem or other device remains active and the line is not assigned to another port.

Fax Routing

When an incoming fax call arrives at the SLSS, the fax CalliNG (CNG) tone or a transfer code directs it to the designated fax port. The SLSS will wait until the Delay Before Routing period has elasped before ringing the default port, but a CNG or transfer code received after the Delay Before Routing, and before the default port is answered, will still route the fax call correctly.

Some faxes do not send the calling tone (CNG). If you have difficulty receiving faxes on one of the SLSS ports and are using the unpublished factory transfer codes (default), change the transfer code for the fax port to a two-digit code (e.g.,

22) so the caller can route faxes manually.

Loss of Power at the SLSS

Duringa powerfailure, telephonesconnectedto Port1 canreceiveand placecalls. No other features of the SLSS will be available. Neither power failure nor restoration will interrupt an ongoing call to Port 1. Incoming calls will be routed to Port 1 if power is lost.

Page 28

Page 37

Reference Manual Chapter 5: Polling Controller and SLSS Operation/Features

Modem Disconnect on Loss of Carrier

Priority disconnection delay during a polling call is minimized if the polling modem “Loss of Carrier” disconnect time is set to a minimum acceptable duration. This duration is called the Modem Disconnect on Loss of Carrier and is a programmable option on most modems. (Please refer to the manual accompanying your modem for further information.)

Incoming Calls to the SLSS

When theSLSS is idle, Port 1 is notconnectedto the incoming CentralOffice line. The SLSS answers all calls at the end of the first ring period, then looks for a transfer code. If it gets a transfer code, the SLSS rings the appropriate port and sends modem answertoneto the Polling Controller,acknowledging the transfer code. The Polling Controller then connectsthepolling modem to the line so data can be transferred. The SLSS then rings the designated port and when the local modem answers, it connects the port to the Central Office line.

Interrupted Incoming Call at the SLSS

If a phone goes off-hook on Port 1 before an incoming call is connected to a port, the SLSS connects Port 1 to the incoming call, and looks for a transfer code from the Polling Controller.

Afterthe SLSSreceivesthetransfercode, ithandlescallsaccordingto theassigned priority access mode (No, Total, or Emergency Priority):

• If the SLSS is programmed for No Priority, the call will be routed to the

appropriate port, and Port 1 will receive busy tone.

-or-

• If in Total Priority Mode, the SLSS will disconnect the incoming call and

connect Port 1 to the Central Office line. In this mode, lower number ports always have priority over higher numbered ports; Port 2 can interrupt an incoming call on Port 3, and Port 3 can interrupt Port 4, etc.

-or-

• If in Emergency Priority Mode, the SLSS sends dial tone to Port 1, and the

user dials one of the programmed emergency numbers. If the number dialed is a valid emergency number, the SLSS will disconnect the incoming call immediately and dials the emergency number as soon as it receives dial tone from the network. The SLSS routes the call unless the caller is denied access due to an invalid number, or 5 seconds elapsed since the last digit was dialed.

Polling Controller and SLSS Feature Operation

ProgrammingTransfer Codes

ThePolling Controllersends transfercodestellingtheSLSS theport towhich calls should be routed. Calls can also be manually routed to any of the ports using a one- to four-digit transfer code. The Transfer Code for Remote Programming is used to enter programming mode. Please see Chapter 4 for more information. If you have changed the defaults, the transfer codes must be programmed on both the Polling Controller and the SLSS before the system will work properly.

Remote Programming

Remote programming offerspassword protection to provide additional security. Thisfeaturemust beenabled viaLocalProgrammingtofurther protectthe system from abuse.

Once remote programming has been enabled at the SLSS, you can program and change the default password from the Polling Controller. When the SLSS is used as a standalone unit, you can use any DTMF telephone connected to the SLSS to change the password.

PrivacyTimeout

If“privacy timeout”is enabled,when anyport goesinto privacytimeout, theport is disabled, the SLSS sends a forced disconnect (COD) to the port, and the SLSS goeson-hook totheincoming (C.O.)telephonelinetoenable otherportsto receive calls. The Privacy Timeout occurs after the SLSS detects: at least five seconds of Central Office dial tone or two cycles of either busy or reorder tone during the first 15 seconds of off-hook, no DTMF digits, and 5 or fewer rotary breaks dialed in 30 seconds. The alarm LED will turn on until the the device on the port goes on-hook.

Ifdial tone, busy, orreorderare notdetected,or dialingis detected,theSLSSlooks for either a hook-flash or forced disconnect. If it detects either one, the SLSS will start the privacy timeout period again. Incoming calls to other ports are routed appropriately, but calls to the off-hook privacy phone get a busy signal.

If the port is returned to on-hook and then goes off-hook later, it will receive Central Office dial tone normally.

Port Off-hook Timeout at the SLSS

TheSLSStimes outwhen theprogrammed maximumcall lengthis exceeded.The SLSS sends a forced disconnect (COD) to the port, and the alarm LED will turn on untilthe device attachedto the portgoes on-hook. Makesure thatthe off-hook timeout is long enough to complete the longest data call.

Note:

If you have selected Emergency Priority, the off-hook timeout on Port 1

will be disabled.

Reference Manual Chapter 5: Polling Controller and SLSS Operation/Features

No Default Routing

Usethis featurewhen allof thedevicesconnectedto theSLSSareused forpolling, including Port 1. It prevents the SLSS from routing calls without transfer codes to Port 1.

If the SLSS does not detect a transfer code, the call is disconnected.

Note:

If power is lost, calls will be sent to Port 1, regardless of this feature.

PostAnswerTransfer

Withthis feature enabled, you can send a call that has been answeredby the Port 1telephoneto anotherSLSS port. To use thisfeature afteranswering a callon Port 1,enter thePost AnswerTransferCodefor thenext port.Once youhave answered the call on Port 1, you have 15 seconds to enter a Port Answer Transfer Code.

Post Answer TransferCodes correspond to the port numbers. Replace the “x” in #0x with the number of the port to which the call will be routed. For example, to transfer a call to Port 2, enter #02, Port 3, enter #03, etc.

❑ For example,

15 seconds.

After answering it on Port 1,

send a call to Port 6 enter #06 within

❑ Hang up the Port 1 phone when you no longer hear the caller.

Post Call Routing

Withthis feature enabled you can send a transfer code to switch fromone port to another after your current call is complete or the port you are calling does not answer. In either case, when this feature is enabled, you have 15 seconds of dial tone during which you can enter a new transfer code.

If, however, Port 1 goes off-hook and the priority mode is set to Emergency or Total, Port 1 is givencontrolof the line. If Ports 2 through 4 or 8 go off-hook, they are treated as No Priority.

To use this feature, the calling modem must be programmed not to hang up on loss of carrier. Please see the modem’s manual for programming instructions.

❑ Make sure Post Call Routing has been enabled. If not, return to the Local or

Remote Standalone Programming instructions and do so.

❑ Dial the SLSS telephone number and enter your password when it answers. ❑ Wait for the Port 1 telephone to answer, then enter the Post Call Routing

Code for another SLSS port.

❑ For example, Enter the Port 3 transfer code: 33 within 4 seconds.

Port 3 will ring and you will hear a high-pitched tone (i.e., the Transfer Code Acknowledge Tone).

❑ Answer the Port 3 call and hang up the Port 3 device when finished.

40-400-00031, Rev. A Page 31

❑ To route to another port on the SLSS during the same call, enter 44 when you

hear dial tone.Port4willring,butyou won’t hear the Acknowledge Tone or three beeps.

❑ Hang up when the last call is finished.

Note:

To use this feature, the calling modem must be programmed not to hang up on loss of carrier. Please see the modem’s manual for programming instructions.

Port Access Priority at the SLSS

Youcan establishone of threetypesof prioritytodeterminehowcompeting users or devices at the SLSS are given access to the line. This is determined by a programming command, as described in Chapter 3. Total, Emergency, and No are the priority modes.

If Total Priority Mode is enabled, Port 1 (normally a telephone) is given immediate access to the line whenever the phone goes off-hook. If another port is using the line (for example, data transfer is taking place), the modem is disconnected and the line freed for the telephone user. Port 2 also has priority access over Ports 3 through 8, but not over Port 1; Port 3 has priority access over Port 4 through 8, but not over Ports 1 and 2, etc.

If Emergency Priority Mode is enabled, a Port 1 user is given priority when one of the programmedemergency numbers is dialed.The SLSS can be programmed to allow up to ten 16-digit numbers.

In this mode, all other ports work as if in Total Priority mode. If you have programmed an Access Code, Port 1 will get access to the line

whenever the access code is entered, regardless of the number dialed.

Caution:

If No Priority Mode is enabled, no port can access the line when another port is using it.

There arecertain conditions under which a caller making a priority interruptcall at the SLSS may not be able to immediately obtain dial tone to make a priority call. The user will experience a dial tone delay and/or receive a busy signal; he should redial in these instances. If, however, the SLSS does not receive a transfer code within four seconds of answering, it rings the default port. The SLSS will disconnect if the following occurs:

• the telephone is not answered within 12 rings (12-50 rings).

• a forced disconnect is received from the Central Office.

• five seconds of dial tone are detected.

Page 32

Page 41

Reference Manual Chapter 5: Polling Controller and SLSS Operation/Features

Ring Detect

Formost applications,use thedefault setting,0. Changetheringdetectionsetting to 1 only if you are using a line isolator that does not comply with Bellcore specifications for ringing signaling. After programming *77#1#, the SLSS will answer the call between 300 - 400 ms after start of the first ring.

Auxiliary Relay

If you have an M-395-B, M-395-D, M-395-E, M-396-B, M-396-D, or M-396-E model, your SLSS includes a latching Auxiliary Relay. If a modem or other microprocessor-controlled device locks up, the Auxiliary Relay can be closed/opened or it can be pulsed closed for ten seconds to activate an external latching relay which will cycle power to or reset the offending device(s) in the substation.

Though the Auxiliary Relay will carry 125 VDC at up to 1 Amp, or 120 VAC (E model 220 VAC) at up to 3 Amps, it is designed to be used with an external relay.

Withthe Auxiliary Relay enabled, you can access it either locally in SecureMode from the Port 1 telephone, or remotely in either a Secure Mode or a Speed Mode from a touchtone telephone or modem. The default Auxiliary Relay position is open and the default access mode is Secure Mode (see Table 2, page 21).

• Auxiliary Relay Secure Mode Operation

Secure Mode requires the user to enter a password before gaining access to Auxiliary Relay operation. This mode requires more steps and works similarly to entering programming commands, except that a special Relay Password is used,not theSystem Password,and theuser isrestrictedto onlyrelay commands.

❑ To access the relay locally, pick up the Port 1 telephone, enter ##, to enter

the Programming Mode, then enter the Auxiliary Relay password (default:

73529). Be sure to terminate the password with the # delimiter.

-or-

❑ To access the relay remotely, call the SLSS through the Polling Controller

with #7 (if SLSS is using Factory Default programming access), or #1 ( if other than Factory Default programming access), appended to the telephone number. When the SLSS answers, wait for the three beep tone indicating Programming Mode, Then enter the Auxiliary Relay password (default: 73529) and listen for three beeps. Be sure to terminate the password with the # delimiter. If no confirmation tone is received, hang-up and repeat this step.

❑ To PULSE (close the relay for ten seconds), enter *31#. You will hear four

beeps after the relay closes, then two beeps after it opens. When you send

40-400-00031, Rev. A Page 33

Page 42

Substation Line Sharing Switch

the Pulse Auxiliary Relay command, the SLSS will not accept any other commands for ten seconds.

❑ To CLOSE the relay, enter: *11#1# and listen for four beeps. ❑ To OPEN the relay, enter: *11#0# and listen for two beeps. ❑ To QUERY the relay about its status, enter: *21#. You will hear four beeps

if the relay is closed, two beeps if it is open.

❑ Hang up when finished.

• Auxiliary Relay Speed Mode Operation

SpeedModeoperation does notrequire youtoenter theProgrammingMode and you use transfer codes rather than programmingcommandsto operate the relay. The Speed Mode (default: Disabled) must be enabled once while in the System Programming Mode . Several operations (transfer codes) can be strung together if the SLSS is also programmed for Post Call Routing (see page 31).

❑ To PULSE (close the relay for ten seconds), when calling through the

Polling Controller with either a modem or a telephone, simply append *16 to the telephone number. You will hear four beeps after the relay closes, then two beeps after it opens. When you send the Pulse Auxiliary Relay transfer code, the SLSS will not accept any other transfer codes for ten seconds.

❑ To CLOSE the relay, using the Polling Controller, one of the available but

un-used routing codes must be programmed to send the transfer code 97 to the SLSS.

❑ To OPEN the relay, using the Polling Controller, one of the available but

un-used routing codes must be programmed to send the transfer code 98 to the SLSS.

❑ To QUERY the relay about its status, using the Polling Controller, one of

the available but un-used routing codes must be programmed to send the transfer code 99 to the SLSS. You will hear four beeps if the relay is closed, two beeps if it is open.

❑ Hang up when finished.

Chapter 6: Standalone SLSS Operation and Features

If you are installing the SLSS, please return to Where To Start in Chapter 1 after reading this chapter.

Although Teltone strongly recommends using the Polling Controller, the SLSS can be used alone, as a standalone unit.

To use the SLSS in this application, you must program the modem dialing string to direct calls to assigned ports. (For example, in Figure 6, modem calls to the Fault Recorderwould be sent to Port 3 andfax calls to Port 4. Fax callsare routed by the Calling or CNG tone.)

Note:

codes from the Polling Controller must be changed to match the ports listed in Table 2. (See command ∗12#y#n#x#.) To change the transfer codes, follow the instructions in the Polling Controller Reference Manual, 40-400-00013.

If a Polling Controller will ever be used with the SLSS, the transfer

Page 36

Figure 6 Standalone SLSS

Page 45

Example: Standalone SLSS Call

A typical polling call from the host computer to a Standalone SLSS would progress as described below:

For this example, the user has programmed the SLSS so that 33 is the code to route the call to Port 3.

The host modem dials the SLSS to access a modem on Port 3. A typical number dialed by the host modem would be:206-487-1515,,,,33

(The “,,,,” are pauses which must be included in the dial string to ensure that the SLSS has time to answer before the transfer code, 33, is sent. The number of pauses depends on the amount of time that the PSTN takes to ring the SLSS and for the SLSS to answer the call.)

The SLSS answers the call at the end of the first ring, then waits a programmable amount of time, the Delay Before Routing (four to 30 seconds, the default is 4 seconds) for a transfer code.If the SLSS does not recognize a transfer code during the wait period, it rings the default port, usually Port 1.

When the SLSS recognizes the valid transfer code for Port 3, it rings Port 3. If the SLSS receives the transfer code before it starts ringing the default port, it sends a transfer acknowledgment tone to the calling modem.

(The modem answer tone is used in case a Polling Controller occasionally calls the SLSS. The tone removes the line split at the Polling Controller.You can program the SLSS so that no acknowledgment tone is sent, a modem answer tone is sent, or a DTMF command, #B, is sent. If a Polling Controller will never be used to access the SLSS, use the first option, i.e., no acknowledgment tone sent.)

At this point, the SLSS has established a metallic path between the incoming telephone line and Port 3 for the data call; the calling and answering modems can now communicate.

Example: Alternative Standalone Call

answer tone by entering

The SLSS can be programmed to answer with either silence (default), a three-beep confirmation tone, or dial tone for the period set in the Delay Before Routing (see ∗70#x# in Table 2).

The host modem dials the polling call to access a modem on Port 3 of the remote SLSS, by dialing: 206-487-1515W33

For this example, you must program the SLSS to respond with a dial tone

40-400-00031, Rev. A Page 37

Substation Line Sharing Switch

The dial tone allows the host dial string to include a W indicating a wait for dial tone before proceeding. (The SLSS has been designed to accept DTMF transfer codes in the presence of SLSS dial tone, but certain network noise and attenuation conditions may prevent this feature from operating in all cases.)

The W avoids guesswork about the number of “,” pauses to put in the dial string. Unfortunately, people calling the SLSS will hear the dial tone and must be instructed to wait for the call to ring the telephone on Port 1.

Standalone Operational Details

Port Access Priority

There are certain conditions under which a caller making a priority interrupt at the SLSS may be unable to immediately obtain Central Office dial tone. In these conditions,theuser willexperience a dialtone delayand/or receiveabusy signal indicating that she/he should redial.

You can establish one of three types of priority which will determine how competing users or devices at the SLSS are given access to the line. This is determined by a programming command.

If Total Priority Mode is enabled, Port 1, normally a telephone, is given immediate access to the line whenever the phone goes off-hook. If another port is using the line (for example, data transfer is taking place), the modem is halted and the line made free for the telephone user.Port 2 also has priority access over Ports 3 and 4, but not over Port 1; Port 3 has priority access over Port 4, but not over Ports 1 and 2.

If Emergency Priority Mode is enabled, a Port 1 user is given priority when one oftheprogrammed emergencynumbers isdialed. (TheSLSS can beprogrammed to allowup to ten 16-digitnumbers and anaccess code toprovide emergencyline access which allows any number to be dialed.) In this mode, Port 2 has total priority over Ports 3 and 4. This arrangement allows calls on equipment connected to Port 2 to take priority over other calls.

Caution:

If one of the SLSS ports is in use when you go off-hook in either Total or Emergency Priority Mode, the SLSS will be unable to obtain network dial tone until the call disconnects or until the PSTN times out (usually within 10-15 seconds).

If No Priority Mode is enabled, no port can access the line when another port is using it.

Loss of Power at the SLSS

Duringa powerfailure, telephonesconnectedto Port1 canreceiveand placecalls, but no other features of the SLSS are available. Existing Port 1 connections will not be interrupted by power failure or restoration.

Calling Party Supervision

The U.S. telephone network typically uses Calling Party Supervision, meaning that even though the called party hangs up, she/he may be reconnected to the callingparty whenthe phoneis takenoff-hookagain.Thecalling partymusthang up for the called party to be fully disconnected before initiating a new call. The telephone network will timeout and disconnect the call within 5-20 seconds, giving the called party dial tone when she/he goes off-hook again. Outgoing Calls from the SLSS

The SLSS allows touchtone and rotary dialing on outgoing calls.

Outgoing TelephoneCalls– SLSS Idle

When a telephone connected totheSLSS goes off-hook, it switches to the Central Office line for dial tone. When the phone goes back on-hook, the line returns to an idle condition. (When the line is idle, it is connected to a local battery feed.)

Outgoing TelephoneCalls– SLSS Active

If in Total Priority Mode, while the modem is active, a priority port going off-hook remains connected to the local battery feed while the SLSS disengages the active port.

-or-

If in Emergency Priority Mode, the telephone at Port 1 receives dial tone (generated internally by the SLSS). Dialed digits are monitored. If the dialed phone number does not match the programmed emergency numbers, busy tone is sent to the telephone user. If, however, the dialed number matches a programmed emergency phone number, the line is freed for the telephone user. The SLSSthen dials the numberand connects tothe Central Officeline. The caller must enterthe emergency number within30 seconds or the SLSS goesinto Privacy Timeout. (This ensures that calls will be routed even if the Port 1 telephone is off-hook indefinitely. See page 30 for more detail about Privacy Timeout.) In this mode, Port 2 has priority over Ports 3 through 8.

If you have programmed an Access Code, Port 1 will get access to the line whenever the access code is entered, even if the number dialed is not a programmed emergency number.

-or-

If in No Priority Mode, the modem or other device remains active and the line is not assigned to another port.

Incoming Calls to the SLSS

When the SLSS is idle, the incoming Central Office line is disconnected from the internal phone line. The SLSS answers all calls at the end of the first ring period. It then monitors for a routing code.

If the telephone is not answered in 1-50 rings (default is 12 rings) or a forced disconnect is received from the Central Office, or dial tone is detected, the SLSS disconnects.If you enter atransfer code beforethe default portanswers, your call will be sent to the port you specified.

If the SLSS does not receive a transfer code within the default four seconds, it routes thecall to the default port. If the default port doesnotanswer the call, you can enter a transfer code to route your call to another port. If a transfer code is received, the SLSS rings the appropriate port.

Interrupted Incoming Call at the SLSS

If a phone goes off-hook on Port 1 before an incoming call is connected to a port, the SLSS connects Port 1 to the incoming call, and looks for a transfer code. After receiving the transfer code, calls are handled according to the assigned priority access mode (No, Total, or Emergency Priority).

If a phone goes off-hook on Port 1 and the SLSS is programmed for No Priority, the call will be routed to the appropriate port, and Port 1 will receive busy tone.

If in Total Priority Mode, a phone goes off-hook on Port 1, the SLSS will disconnect the incoming call and connect Port 1 to the Central Office line. In this mode, lower numbered ports always have priority over higher numbered ports; Port 2 can interrupt an incoming call on Port 3, and Port 3 can interrupt Port 4, etc.

If in Emergency Priority Mode, a phone goes off-hook on Port 1, the SLSS sends dialtone toPort 1for theuser todial oneof theprogrammedemergencynumbers. The SLSSwon’troute the incomingcall until either thecaller is deniedaccess due to an invalid number, or 5 seconds pass since the last digitwasdialed. Ifnumber is valid, the SLSS disconnects immediately.

Standalone Feature Operation

Standalone Defaults

Enteringthe Fetch StandaloneDefaultscommand, ∗00#∗02#,enablesthe defaults for standalone operation listed in Table 2. These default values offer basic standalone operation, and, like other defaults, can be changed to values that better suit your application.

If you change the values and need to return to the standalone defaults, enter ∗00#∗02, the Fetch Standalone Defaults command. This will erase the changes youhave madeandreturnthe unitto theStandalonedefaultvalueslistedin Table

SLSS Answer Tone

If youhave enabled thisoption, an answertone is sentto thecallerwhen theSLSS answers a call.Thetone can be three beeps or dial tone. If this featureisdisabled, no answer tone will be sent (default).

Note:

The SLSS has been designed to accept DTMF transfer codes in the presence of SLSS dial tone, but certain network noise and attenuation conditions may prevent this feature from operating.

Remote Programming

A password-protected remote programming capability is provided. This feature must be enabled via Local Programming before it can be used.

Pause for Transfer Code

The SLSS will pause after answering a call and wait for a transfer code. You can program the SLSS to pause for any period of time between 4 and 30 seconds (default is 4 seconds).

AcknowledgmentTone

When this function is enabled, the SLSS sends an acknowledgment tone to the caller if a transfer code is received before the SLSS starts ringingthedefault port. You can choose modem answer tone or a two-digit DTMF tone.

Hang Up Default Port

This feature should be used when the SLSS is connected to a line that does not have forced disconnect, such as a PBX line. If a call is routed to the default port because it does not have a transfer code, callers have the option of hanging up before the port answers.

❑ Enter ##before the default port answers to hang up. ❑ When you hear dial tone, you can call the SLSS again to call a different port

or you can call another number.

40-400-00031, Rev. A Page 41

PostAnswerTransfer

Withthis feature enabled, you can send a call that has been answeredby the Port 1telephoneto anotherSLSS port. To use thisfeature afteranswering a callon Port 1,enter thePost AnswerTransferCodefor thenext port.Once youhave answered thecallon Port 1,you have 15seconds toentera PortAnswer TransferCode.(The codes are listed in Table 2.)

❑ For example, After answering it on Port 1, send a call to Port 6 enter #06

within 15 seconds.

❑ Hang up the Port 1 phone when you do no longer hear the caller.

Post Call Routing

Withthis feature enabled you can send a transfer code to switch fromone port to another after your currentcall is complete or the first port to which your call was routed has completedtheprogrammed number of rings. In either case, you have 15 seconds to enter a new transfer code.

To use this feature, the calling modem must be programmed not to hang up on loss of carrier. Please see the modem’s manual for programming instructions.

❑ Make sure Post Call Routing has been enabled. If not, return to the Local or

Remote Standalone Programming instructions and do so.

❑ Dial the SLSS telephone number and listen for three beeps. ❑ Enter the transfer code for the first port you wish to call. (If you have

enabled the Transfer Code Acknowledgment Tone, you will hear a tone.)

❑ After completing the call and hearing dial tone, the called modem must

hang up. If you have enabled the Transfer Code Acknowledgment Tone, you will hear a tone, then enter a second transfer code to ring the other desired port.

Note:

hang up on loss of carrier. Please see the modem’s manual for programming instructions.

Modem Disconnect on Loss of Carrier

Any priority disconnection delay during a polling call will be minimized if the polling modem “Loss of Carrier” disconnect time delay is set to a minimum acceptable duration. This duration is called the Modem Disconnect on Loss of Carrier and is a programmable option on most modems. (Refer to the manual accompanying your modem for further information.)

To use this feature, the calling modem must be programmed not to

PrivacyTimeout

If “privacy timeout” is enabled and a port goes into privacy timeout, the port becomesidle,the SLSS willsend a forceddisconnect (COD) tothe offendingport, hang up the incoming (C.O.) telephone line to enable other ports to receive calls, and light the Alarm LED until the offending device is returned to the on hook condition.. This happens after the SLSS first detects at least five seconds of Central

Office dial tone or two cycles of either busy or reorder tone during the first 15 seconds of off-hook, and no DTMF digits and 5 or fewer rotary breaks dialed in 30 seconds.

If dial tone, busy, or reorder were not detected, or dialing was detected,theSLSS will monitor for either a switchhook flash, dial tone, or forced disconnect. If a switchhook flash or forced disconnect is then detected, the SLSS will re-start the privacy timeout period. No tones are sent to the off-hook phone. Incoming calls to other ports (transfer code received from the Polling Controller) are routed appropriately; calls to the off-hook privacy phone are given busy tone.

If the port is returned to on-hook and then goes off-hook later, it will receive Central Office dial tone per normal operation.

Port Off-hook Timeout at the SLSS

If acall exceeds themaximum call lengthprogrammed withcommand∗10#y#n#, it will be disconnected. To continue using the single Central Office line during these conditions, a programmable off-hook timeout is provided. When the Port Off-hook Timeout begins, the SLSS will send a forced disconnect (COD) to the offending port, hang up the incoming (C.O.) telephone line, and the alarm LED will light until the device on the port goes on-hook. This off-hook timeout should

allow enough time for the expected duration of the longest polling call.

Ring Detect

Auxiliary Relay

If you have an M-395-B, M-395-D, M-395-E, M-396-B, M-396-D, or M-396-E model, your SLSS includes a latching Auxiliary Relay. If a modem or other microprocessor-controlled device locks up, this relay can be closed/opened or it can be pulsed closed for ten seconds to activate an external latching relay. The latchingrelay canin turnbe usedtocyclepowertoorreset theoffendingdevice(s) in the substation.

Though the Auxiliary Relay will carry 125 VDC at up to 1 Amp, or 120 VAC (E model 220 VAC) at up to 3 Amps, it is designed to be used with an external latching relay to effect the power switching.

Thedefault AuxiliaryRelayposition isopenandthedefault accessmodeis Secure Mode (see Table 2, page 21). You can access the relaylocally in Secure Mode from

• Secure Mode Operation

Secure Moderequires you to entera password before gaining accessto Auxiliary Relay operation. This mode involves more stepsandworks similarly to entering programming commands, except that a special Relay Password is used, and the user is restricted to only relay commands.

❑ To access the relay locally, pick up the Port 1 telephone, enter ##, to enter

the Programming Mode, then enter the Relay Password (default: 73529). Be sure to terminate the password with the # delimiter.

-or-

❑ To access the relay remotely, call the SLSS and dial #1 after the SLSS has

answered.. Wait for the three beep tone indicating Programming Mode, then enter the Relay Password (default: 73529) and listen for three beeps. Be sure to terminate the password with the # delimiter. If no confirmation tone is received, hang-up and repeat this step.

❑ To PULSE (close the relay for ten seconds), enter *31#. You will hear four

beeps after the relay closes, then two beeps after it opens. When you send the Pulse Auxiliary Relay command, the SLSS will not accept any other commands for ten seconds.

if the relay is closed, two beeps if it is open.

❑ Hang up when finished.

• Speed Mode Operation

SpeedModeoperation does notrequire youtoenter theProgrammingMode and you use transfer codes rather than programmingcommandsto operate the relay. The Speed Mode (default: Disabled) must be enabled once while in the System Programming Mode. Several operations (transfer codes) can be strung together if the SLSS is also programmed for Post Call Routing (see page 42.).

❑ To PULSE (close the relay for ten seconds), send the transfer code 96. You

will hear four beeps after the relay closes, then two beeps after it opens. When you send the Pulse Auxiliary Relay transfer code, the SLSS will not accept any other transfer codes for ten seconds.

❑ To CLOSE the relay, send transfer code 97 to the SLSS. You will hear four

beeps after the relay closes.

Chapter 7: Daisy-chain Operation

If you are installing the SLSS, please return to Where To Start in Chapter 1 after reading this chapter.

Daisy-chaining is linking a series of SLSS units together through Port 1. In this typeof operation,theSLSS unitsandthePollingControllerwork togethertoroute calls.

If you are daisy-chaining the M-395-A, B, D, or E, four-port models, up to four SLSS units can be daisy-chained; however, if you are using the M-396-A, B, D, or E, eight-port models, a maximum of two SLSS units can be daisy-chained.

Daisy-chainedunits operatejustas theywouldnormally,with oneexception:Port 1 of the first SLSS is always used to connect to the next SLSS through its CO Line port. The last SLSS in the chain can use Port 1 to connect to an emergency telephone. Other ports can be used to connect any other device that would normally be used with a SLSS (e.g., modems, fax machines, etc.).

Reference Manual Chapter 7: Daisy-chain Operation

Daisy-chain Features

All of the features described in Chapter 5 are available in daisy-chain operation with a Polling Controller; however, the function of priority modes (Emergency, Total, and No Priority) is slightly different.

Note:

For information on changing the proprietary defaults for transfer codes in daisy-chain applications, please refer to the tables in Chapter 3.

For the following explanation, assume that three SLSS units are being daisy-chained as indicated in the illustration.

In order to use Emergency Priority, program the last SLSS in the chain for Emergency Priority and all others for Total Priority. The last SLSS in the chain will have priority over all others in the chain. When an emergency call is made, the Total Priority mode of other units up the chain will cause any call in progress to be terminated. As soon as dial tone is received from the PSTN, the emergency call will be processed.

If you assign Total Priority to all SLSS units in the chain, devices connected to ports on the first and second SLSS will be disconnected if any port on the last SLSS goes off-hook.

Caution:

If you assign NoPrioritytoanyoftheSLSS units, calls will never be interrupted. This setting is not advised for applications requiring a telephone in emergency situations.

Programming for Daisy-chained SLSS Units

Daisy-chained SLSS units can be programmed either locally or remotely. After carefullycompletingthis section, follow theinstructions in Chapter 3to program the units. If you use Emergency Priority, remember to program the same ten emergency telephone numbers into all SLSS units and to program the same emergency access code into all units.

Please refer to the table below for programming daisy-chain applications. The SLSSportcolumn isdivided intotwosections toaccommodate boththe four-and the eight-port model SLSS.

Note:

For reference only, Unit 1 is the first SLSS in the daisy-chain, Unit 2 is

the second, etc. When assigning transfercodesfor remote programming or for ports (commands

∗07#n#x# and ∗12#y#n#x#), all codes must be unique and must have the same number of digits.

❑ Select a port on one of the daisy-chained SLSS units. ❑ Choose the routing codes (∗04 or ∗09 - ∗16) that you want associated with

that port.

❑ Assign a unique transfer code to that port. ❑ Fill in the table on the next page by assigning the transfer codes to units

and ports.

Note: Submitting the routing code *16 to a Polling Controller will generate a transfer code which will pulse the Auxiliary Relay on M-395-B, M-395-D, M-395-E, M-396-B, M-396-D, and M-396-E models of the SLSS.

Appendix 1: About the SLSS

SLSS Models

The M-395-A-02 has four ports and the M-396-A-02 has eight ports. With the exceptionof thenumberof portsand theirtransfercodes,the modelsareidentical. The M-395-B/M-396-B are similar to the A-02 models except that an Auxiliary Relay and operational control for the Auxiliary Relay are included. The M-395/M-396-D, and E are similar to the B-01 units, except they use AC voltage.

Dimensions and Shipping Weight

Each SLSS is enclosed in a housing 2.37" high by 12.00" wide by 11.80" deep. The shipping weight for each of the SLSS models is approximately 8 lb..

Fuse

The SLSS is protected by a 1.5 amp, Slo-blo 3 AG, 250 V external fuse. You can remove this fuse to turn off the SLSS.

Connectors

Power screw terminals, alarm screw terminals, and line jacks are located on the rear panel. The requirements for each are listed below: For the “A” and “B” models, power/status: the Nominal 42-150 VDC 600 mA maximum input power connects to the screw terminals marked positive (+) and negative (-). The first terminal is the ground. The yellow terminal block cover throughwhich the wiresare fedcan be removedfor accessto the screwterminals. The cover should be replaced to prevent shock.

• The M-395-D-01 and the M-396-D-01 units operated from 90 to 150 VAC.

Their maximum current draw is 250 mA at 120 VAC.

• The M-395-E-01 and the M-396-E-01 units operated from 90 to 220 VAC.

Their maximum current draw is 250 mA at 220 VAC.

• Alarms A1 and A2: Use of these connectors is optional. Connect alarm

monitoring equipment to these normally open contacts. Please refer to the description of the Alarm LED on page 2.

• R1 and R2 AUX: The terminals labeled R1 and R2 are used to connect to

the dry Auxiliary Relay contacts on M-395-B-01, D-01, E-01, M-396-B-01, D-01, and E-01 models only. The terminals are not operational in the M-395-A-02 and M-396-A-02 models. The corresponding front panel LED, labeled AUX, is only present on M-395-B-01, D-01, E-01, M-396-B-01, D-01, and E-01 models. The AUX LED is lit when the Auxiliary Relay is closed, and not lit when the Auxiliary Relay is open.

• CO Line: an RJ-ll jack for connection of the incoming Central Office

telephone line. The incoming line must be a standard loop start line.

• Ports: four or eight RJ-11 device ports. Port 1 is the highest priority device

port; if a telephone is to use the line it should be connected to Port 1. Ports 2 through 8 are interchangeable and are used to connect other devices sharing the line.

Reference Manual Appendix 2: Troubleshooting

Appendix 2: Troubleshooting

If you are having difficulty with the SLSS, please follow these steps before calling Technical Support.

On-site Troubleshooting

❑ Check the connections between the devices and the SLSS. Are they secure? ❑ Is the SLSS connected to the correct telephone line? This applies only if

more than one telephone line comes into the substation. Make sure all substation phones are connected to Port 1 if the telephones are to share the line with other devices.

❑ Check the line polarity. See the Incoming Line Polarity section, below. ❑ Check the power. If you hear three beeps when you call the unit remotely

and enter the remote programming transfer code, it has power and is operating. (If power is lost to the SLSS, a direct path between the Telco Line port

and Port 1 is maintained.)

❑ Check that the dial string has the correct number of digits. ❑ Check that the transfer codes for remote programming and/or ports are a

match between the Polling Controller and SLSS, if you are not using the default values. The Factory Default transfer codes are proprietary and require a Polling Controller to remotely access the SLSS programming mode and to ring any of the SLSS ports. The SLSS must be programmed

to Stand Alone or user programmed transfer codes to steer calls without a Polling Controller.

❑ If you are unable to use Remote Programming, make sure that the Remote

Programming feature is enabled.

❑ Check the pause (,,,,) time. If you are using a modem and adding the pause

manually, make sure that the pause time is correct. If not, add or delete commas one at a time until SLSS answers the call. (Please see the manual accompanying the modem for further instructions.)

❑ Return to defaults by entering ∗00#∗00# and begin programming again.

Incoming Line Polarity

Incorrect line polarity can degrade the performance of the SLSS and may cause problems with certain modems. To avoid this problem and maximize the performance ofthe SLSS, verify thatthe polarity oftheincoming linematchesthe polarity of the SLSS. You can purchase a telephone line polarity tester from any

40-400-00031, Rev. A Page 53

Page 62

Substation Line Sharing Switch

telecommunications distributor. Plug the tester into Port 2 of the SLSS while the unit is powered. Verify that the Tip/Ring polarity is not reversed.

If you are experiencing a problem with the modem disconnecting and tester is unavailable, reverse the tip and ring of the incoming line.

Routing Delays

Some telephone systems cause a momentary glitch as soon as the telephone number is dialed. This can interfere with the routing code sent by the Polling Controller. If this occurs, insert a delay (i.e., comma) between the last digit of the telephone number and the routing code.

❑ Use 12064871515,*02 instead of 12064871515*02

Fax Routing Problems

Some faxes do not send the calling tone (CNG) the SLSS needs to route fax calls. If you have difficulty receiving faxes on one of the SLSS ports and are using the unpublished factory transfer codes (default), change the transfer code for the fax port to a two-digit code (e.g., 22) so the caller can route faxes manually.

Modem Lock Up

If a modem or another microprocessor-controlled device gets “stuck” off-hook, usethe auxiliaryrelayto resetit.(The relayisonly availablewithmodels M-395-B, M-395-D, M-395-E, M-396-B, M-396-D, and M-396-E.)

2500 set

The standard single-line touchtone desk telephone.

Abbreviated dialing

A feature of telephone systems that allows a caller to dial one or two digits to place a call. The system translates the digits to the actual number being called. Also known as “speed dialing”.

BusyTone

A signal generated by the Central Office indicating that the line you are calling is busy.

Call ProgressTone

A tone sent from the switch to tell the caller of the progress of the call. Examples are audible ringing, re-order, busy, timing, etc.

Central Office

Telephone company facility where subscribers’ lines are joined to switching equipment for connecting other subscribers to each other, locally and long distance. (Also called CO.)

Centrex

Business telephone service offered by a local telephone company from a local Central Office. Centrex is leased to businesses as a substitute for a business-owned PBX or key telephone system.

A decibel is a unit of measure for expressing differences in signal strengths.

DTMF

Also called touchtone. Dual-tone multi-frequency. Push-button telephone signaling.

Factory Default

A setting programmed by Teltone. If necessary, you can change this value with one of the programming commands. If necessary, use theRestore Defaults command to return to factory defaults.

Forced disconnect

Method used by the telephone company to clear a line. When the called party goes on-hook, the Central Office returns an open (that is, drops loop current) of at least 800 ms to the calling party. This is also known as Calling Party Control (CPC), or Cutoff on Disconnect (COD).

Reference Manual Appendix 6: Glossary

Ground start

One of two types of switched telephone lines (outside lines) typically leased from telephone companies, the other type being “loop start”. A ground start telephoneline initiates an outgoing telephone line seizure by applying a local resistance up to 550 ohms from ground to the tip conductor.

Key telephone system

A telephone system in which the telephones have multiple buttons that permit a user to select outgoing or incoming Central Office phone lines directly.

LED or light

Light-emitting diode. A semiconductor diode that emits light when a current is passed through it. Used for status and information displays on electronic devices.

Loop start

One of two types of switched telephone lines (outside lines) typically leased from telephone companies, the other type being “ground start”. Aloop start telephone line is seized by connecting a low resistance between the tip and ring (both wires) of the telephone line. This occurs whenever a telephone or modem goes off-hook. If you need to find out if a line is loop start, call the telephone company.

Off-hook

The telephone is in an off-hook state when the handset is removed from the cradle. A modem or other device is off-hook when it answers a call or when it seizes a line to initiate a call.

Public Switched Telephone Network (PSTN)

Usually refers to the worldwide voice telephone network accessible to all those with telephones and access privileges (i.e., In the U.S., it was formerly called the Bell System network or the AT&T long distance network.)

Remote

At a location physically removed from the equipment in question, that is, a computer or PBX system that can be accessed by dialing through the telephone network.

ReorderTone

A tone that sounds like the busy signal, but is twice as fast. It indicates that all switching paths are busy. If you hear a reorder or “fast busy”, hang up and dial the number again.

Routing Code

This series of digits is sent to the Polling Controller by the calling device, usually a modem. When the Polling Controller receives the routing codes, it translates them into a transfer code and sends the transfer code to the SLSS.

Touchtone

See DTMF.

Transfer Code

This code is a translation of the routing codes sent to the Polling Controller. The transfer code tells the SLSS the port to which a call should be routed.
