• 4 highly featured Trunks (COIC, FXO) in a
single Module.
• Magnetic isolation providing high common
mode rejection (CMRR) for use in
un-grounded systems.
• Highly integrated with on board loop switch
and integral diode bridge.

• Loop Start operation with On-Hook
reception and reversal detect (for Caller
Line ID and remote metering).
• Ringing detection and Loop Current
detection.
• Meets requirements of EN60950/UL1950,
and FCC Pt68.
Control and
Supervision
• Minimum number of external components,
single +5V system side power supply.
• Programmable d.c. mask.
DESCRIPTION
The Silver Telecom Ag2410 comprises four
individual Trunk Circuits in a single Module.
The combination of features and packaging
offers extremely efficient use of board area,
saving significantly on system size and cost.
The Ag2410 has been designed to work with
600R line impedance and meets international
safety and regulatory requirements.
In addition to the features shown above the
Ag2410 allows flexible programming of many
functions, including the dc voltage mask.
• Silver Telecom “design-in” assistance.
Each circuit requires a minimum of external
components and has been specified for ease
of use, to reduce time to market.
The system interface has been designed for
direct connection to popular Codecs of both
the audio and signalling connections.
The Ag2410 is designed for applications
where there is a high level of common mode
interference, such as PABX, long loop
applications and systems without a ground.

Table 2: Line and Network Balance Impedance Examples
3.2 The 2 Wire Impedance
3.3 Network Balance Impedance
The input impedance, ZIN, of each circuit is set
internally to 600R. To provide other impedances, use
a codec where the internal filter characteristics can be
programmed to provide the correct matching. In order
to generate the filter coefficients a model of the Ag2410
must be used. This file, in .CIR format is available on
request from Silver Telecom or one of our
representatives.
Full details on how the Codec is programmed must be
obtained from the Codec manufacturer.
The setting of the network balance can be done by
programming of the Codec, using the .CIR file, or it can
be done by hardware components.
If the hardware technique is used a network must be
connected between Zb and Vin. Common examples are
shown in Table 2.
