The OV-023 is a splitter module that has been specifically designed to complement the functionality of low pass filter in POTS over ADSL application at CPE side. It integrate low pass filter that block the high frequency energy from reaching the POTS device and provide isolation from impedance effects of the POTS device on ADSL. It provides Line port, Phone port and Modem port.
For POTS voice band service, the low pass filter provide protection from ADSL signal which may impact through non-line or other effects remote devices (handset, fax, voice band modem etc.) and central office operation.
For ADSL signal, it also provide protection from the high frequency transient and impedance effect that occur during POTS operation (ringing transients, on-hook, off-hook transient and so on).
The circuit protection will be provided mostly by standard central office line protection means and additional protection measures built into pots splitter to protect against line overstress which could damage the splitter itself.
