Global Enhanced Multiport Integrated
ADSL Transceiver
GEMINAX
Applications
■ All memory on-chip, no external
■ External ringing supported
■ Programmable thresholds for
on-hook, off-hook and ring trip
detection
■ Integrated DCXO for synchroni-
zation of PCM voice and ADSL
data subsystems
■ Splitterless multirate ADSL data
transmission combined with
POTS voice for CO, Access
Network, MSAP and DLC
memory required for GEMINAX
■ Future proof due to software
upgrade options
■ Programmable digital filters for
country specific settings like:
- Impedance matching
- Transhybrid balancing
- Frequency response
- Gain
