POTS Module Configuration
Standard configuration
One Unit A
(SAPTF33xx-105)
module and one Unit B
(SAPTF33xx-115)
module are
required for the standard configuration. The Unit A module is connected to the Central
Office (CO) or PBX while the Unit B module is connected to a telephone terminal
equipment. See Figure 1.
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
(SAPTF33xx-115)
modules connected via the fiber ports
(a telephone Device at
each end)
is the requirement for this configuration. See Figure 2.

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 or
failure of the module.
Set the jumpers
Note:
The jumper
(on pins 1 and 2)
of header JP1 on the -115 only is set at the
factory, and must be in place for proper operation.
Using small needle-nosed pliers or similar tool to move the jumper to the desired
position.
Standard/automatic ring-down
Header JP2 is used to switch between the Standard or Automatic Ring-Down
configuration. The header is located on the top circuit board of Unit B
(SAPTF33xx-
115)
module
.
The jumper has been factory set to the standard setting, JP2, pins 1
and 2 as the default.
Figure 3 shows the jumper settings on the 115 circuit board.
•
Set jumper JP2 on Unit B module to the Standard setting when using the
Standard configuration
(Unit A module connected to a central office line and
Unit B directly to a phone).
•
Set jumper JP2 on both Unit B modules to the Automatic Ring-Down setting
when using the Automatic Ring-Down configuration
(fiber connection).
Telephone regulation
The loop current header JP2 is labeled “H” for high loop current ETSI
TBR21standard compliant telephone lines, and “L” for low loop current
(20 – 30
mA)
standard compliant telephone lines. Header JP2 is located on the circuit board
of Unit A
(SAPTF33xx-105)
module
.
This feature is required to comply with ETSI
telephone-line regulations. The jumper has been factory set to the low loop current
setting, JP2, pins 2 and 3 as the default.
Figure 4 shows the jumper settings on the 105 circuit board.
