Data Sheet
Ag2130
LOW COST PSTN INTERFACE
PTD3A350H26. (Metallic protection with a single
device is all that is required, as the Ag2130 will
withstand longitudinal voltages up to 1000Vrms to
ground without additional protection).
As an option, for improved off-hook power cross
protection, the Ag2130 has been designed to interface
directly to the STM TPP25011. This protection
arrangement is shown in figure 6b.

Regulatory Standards
There are some aspects of international standards that
are not fully met by the Ag2130. These are shown
below. It is Silver Telecom’s policy to bring to the
attention of customers all known exceptions.
The Ag2130 meets the requirements of EN60950-1:
2001 paragraph 6.1.2.1 for all countries except
Norway, Sweden and Finland. Please contact Silver
Telecom if the product is needed for these countries.
The Ag2130 has been approved to the following safety
standards:
EN 60950-1:2001
IEC60950-1: First Edition 2001
AS/NZ60950-1: 2003
UL60950-1: 2003 1
st
Edition
CSA 22.2 No.60950-1-03 1
st
Edition
In order to maintain this approval when the Ag2130 is
incorporated into a host system care must be taken to
maintain the user protection provided in the Ag2130 by
ensuring adequate separation of the line side circuitry
and components from the protected circuit so that the
barrier is not compromised. The system should be
housed in a fire enclosure made of a suitable flame
retardant material.
For USA and Canada the line cord connecting the
system to the network must have minimum 26AWG
conductors.
User/Network safety from mains power voltage
(EN60950 paragraphs 2.1.1 and 6.1) must be provided
externally by a power supply with reinforced or double
insulation.
6.0 Layout
Signal tracks should be kept as short as possible.
Special attention should be paid to DMa, DMb and Z
B
as these are sensitive nodes.
