Standard Configuration

One Unit A device (SAPTF33xx-100) and one Unit B device (SAPTF33xx-110) are required for the standard configuration. The Unit A device is connected to the Central Office (CO) while the Unit B device is connected to a telephone device.

Automatic Ring-Down Configuration

Automatic Ring Down (ARD) is a dedicated, point-to-point voice system. When one telephone is taken off-hook, the other telephone rings, without the need to dial. Two Unit B devices (SAPTF33xx-110), connected via the fiber ports, are required for this mode of operation; with a telephone device at each end.

Installation

CAUTION: Wear a grounding device and observe electrostatic discharge precautions when setting the jumpers. Failure to observe this caution could result in damage to, and subsequent failure of, the media converter.

Setting the Jumpers

1.Using a small screwdriver, remove the screws that secure the cover to the media converter and carefully remove the cover.

2.Locate the jumpers on the circuit board.

3.Using small needle-nosed pliers or similar device, move the jumper to the desired position. (Refer to the drawings below.)

4.Carefully replace the cover on the media converter and replace the screws to secure the cover.

Standard / Automatic Ring-Down

The jumper labeled “JP1” is used to switch between the Standard or Automatic Ring-Down configuration and is located on the top circuit board of Unit B (SAPTF33xx-110).

The drawing below illustrates the jumper settings.

•Set jumper JP1 on the Unit B device to the Standard setting when using the Standard configuration (described on page 4).

•Set jumper JP1 on both Unit B devices to the Automatic Ring-Down setting when using the Automatic Ring-Down configuration (described on page 4).

US / EU Telephone Regulation

The jumper labeled “US EU” is used to switch between the US or EU telephone configuration and is located on the top circuit board of Unit A (SAPTF33xx-100). This feature is required to comply with the EU TBR21 telephone regulation. The jumper has been set at the factory to the US setting as the default.

The drawing below illustrates the jumper settings.

•Set jumper “US EU” on the Unit A device to the US setting if the device is to be used with US-based telephone systems.

•Set jumper “US EU” on the Unit A device to the EU setting if the device is to be used with European-based telephone systems.

Installation -- Continued

Grounding the Media Converter

The SAPTF33xx-1xx single-slot chassis comes equipped with grounding lugs located on the back panel. They require a grounding conductor wire terminated with a two-hole, compression-type, grounding connector. The grounding wire -- which must be a copper conductor -- is not included with the chassis and must be provided by the customer/installer.

The electrical conducting path from the single-slot chassis must:

•Flow via the grounding lugs to the common bonding network (CBN).

•Be of sufficiently low impedance to conduct fault currents likely to be imposed on the media converter, and

•Enable proper operation of any over-current protection devices.

The conductor must be fastened to the grounding lugs with the enclosed antirotation star-washers and lug-nut fasteners. The applied torque required to the connector lug-nut fasteners is specified by the connector’s manufacturer.

To properly ground the SAPTF33xx-1xx single-slot chassis:

1.Obtain one (1) grounding conductor (12 AWG copper wire gauge or larger) with a two-hole, compression-type, grounding connector.

2.Attach the grounding conductor to the converter by placing the two-hole connector onto the grounding lugs and fasten with the enclosed lockwashers / lug-nuts at the proper torque (per the manufacturer’s specification).

Loop-Start Operation

Loop-Start Service -- commonly known as “Plain Old Telephone Service” (POTS) -- is the primary analog signaling method used between telephone switches such as the Central Office (CO) and a telephone device. Loop-Start provides a way to indicate on-hook and off-hook conditions, which facilitates outgoing and incoming calls in a voice network.

When a customer wants to make an outgoing call, he or she takes a telephone device off-hook. This action completes the loop, which signals the CO that a customer desires to use the telephone line. To signal the customer of an incoming call, the CO applies a ring voltage to alert the customer.

The three states of the Loop-Start signaling protocol are described below:

Idle State (On-Hook)

1.The CO applies a battery voltage to the ring lead and monitors the tip-ring current for closure of the tip-ring.

2.The telephone device draws less than 10 µA of from the line while waiting for the superimposition of the ringing voltage over the ring lead.

Telephone In-Use (Off-Hook)

1.The customer takes the telephone device off-hook, drawing a minimum of 20 to 30 mA of current.

2.The CO senses the tip-ring current and issues a dial tone on the line.

3.Communication can now begin.

Central Office (CO) Rings the Telephone

1.The CO superimposes the ringing voltage over the ring lead battery.

2.The telephone device uses the ring voltage to operate the ringer, which alerts the customer of an incoming telephone call.

3.The customer takes the phone off-hook, which closes the tip-ring connection and allows the tip-ring current to flow.

4.The CO senses the DC current from the telephone device and connects the call to the telephone line.

5.Communication can now begin.
