  • Page 10: Chapter 2: Overview

    Line Sharing Switch Chapter 2: Overview The Teltone Polling Controller and LSS enable businesses using multiple dedicated telephone lines for short-duration data transfers to save costs through line sharing. In companies where headquarters regularly poll branch offices for data collection, the system allows devices, such as modems, to share a phone line at the remote location.

    Teltone Polling System. These types of telephone lines are also known as Analog Line, POTS (plain old telephone service) lines, and Single Line Telephone circuits. The LSS will not operate on digital lines or ground start trunk circuits.

  • Page 12: Basic Operation

    Line Sharing Switch Programmable Transfer Codes This group of features improves security by allowing you to specify the DTMF tones which route calls at the LSS, ensuring that calls are transferred to the appropriate port. Transfer codes can be programmed so that the LSS can be used with and without a Polling Controller in the same application.

  • Page 13: Chapter 3: Installing The Lss

    A UL and CSA approved AC to DC transformer is included which converts the input voltage to the 24 VDC required by the unit. Ports: two, three, or four RJ-11 device ports (models M-392-A/B, M-393-A/B, and M-394-A/B, respectively). Port 1 is the highest priority device port; if a telephone is to use the line it should be connected to Port 1.

    Line Sharing Switch Mounting Options The LSS is shipped with adhesive mounting pads, each with adhesive backing for mounting the unit to a wall or other surface, shown in Figure 4. The LSS may also be mounted on a wall using mounting strap (UM-110-101), shown in Figure 3 and available as an ordering option.

  • Page 20 Line Sharing Switch Calling Party Supervision The U.S. telephone network typically uses Calling Party Supervision. This means that even though the called party hangs up, they may be reconnected to the calling party when their phone is taken off-hook again. The calling party must hang up in order for the called party to be fully disconnected and initiate a new call.
  • Page 21 DTMF transfer code is not received, the call is routed to Port 1, and the off-hook port will be left connected to the local battery feed. No tones will be sent to the port. 40-400-00015, Rev. F Chapter 4: Teltone Default LSS Operation with Polling Controller Page 13...
  • Page 22 Line Sharing Switch Off-hook Timeout at the LSS Occasionally, a need to set a maximum off-hook time is required. The LSS allows either no limit or a programmable maximum time of up to 255 minutes per port. After an off-hook timeout timer expires, the device connected to the port will be sent a forced disconnect (COD) and the C.O.

    Line Sharing Switch Chapter 5: Standalone LSS Operation and Programming This chapter is used for M-39X-B-01 models only. The LSS can be used with or without the Polling Controller. In this Standalone mode, the modem or fax dialing string must be programmed to direct calls to assigned ports. (For example, in Figure 6, modem calls to the POS server would be sent to Port 3 and fax calls to Port 2.) The LSS can have two, three, or four ports.

  • Page 29: Figure 5 Standalone Line Sharing Switch

    Reference Manual Figure 5 Standalone Line Sharing Switch Programming Transfer Codes The Polling Controller sends transfer codes to the LSS indicating the port to which calls should be routed. Calls also can be manually routed to any of the ports using a one- to four-digit transfer code.

You can establish one of three types of priority which will determine how competing users at the LSS are given access to the line. This is determined by a programming command, as described in Chapter 4.
  • Page 31 Reference Manual Telephone Calls—Modem Active If in Total Priority Mode, and the modem is active, a priority port going off-hook remains connected to the local battery feed while the LSS disengages the active port. To do this, the LSS forces the modem on-hook (terminating the modem carrier), then sends a disconnect command to the Polling Controller and receives acknowledgment that the Polling Controller has gone on-hook, then goes on-hook towards the central office to obtain a new dial tone for the calling party.
  • Page 32 Line Sharing Switch the LSS connects Port 1 to the incoming call, and monitors for a DTMF transfer code from the host site Polling Controller. If a DTMF transfer code is received, the LSS will split the line. What happens next depends on which priority interrupt mode has been programmed.

    4 ports. Two typical applications are described in this chapter. The first is a distributed application using Standalone operation, and the second is a daisy-chain configuration using Teltone Default operation. Cascaded units operate just as they would normally, with one exception: Priority operation via Port 1 must always be connected from port 1 of the primary LSS to the Jack A input of the cascaded LSS, see Figure 7.

  • Page 39: Programming For Cascaded Lss Units

    Reference Manual For the following explanation, assume that three LSS units are being cascaded as indicated in the illustration. If you assign No Priority (default) to all LSS units, equal access is given to the Central Office line for all ports. If you assign Total Priority to the first LSS unit and the LSS connected to Port 1, devices connected to ports on the first and second LSS will be disconnected if Port 1 goes off-hook.

  • Page 40: Programming For Daisy-Chained Lss Units

    Line Sharing Switch In order to use Emergency Priority, program the last LSS in the chain for Emergency Priority and all others for Total Priority. The last LSS 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.

    Reference Manual Routing Code When assigning transfer codes for remote programming or for ports, all codes must be unique and must have the same number of digits. Select a port on one of the daisy-chained LSS units. Choose the routing codes (*01 - *16) that you want associated with that port. Assign a unique transfer code to that port.
