POTS Interface
Each POTS interface on the Total Access 1224 accepts a POTS signal from the CO and passes
it through to the ADSL2+ plus POTS interface for delivery to the customer. POTS service is not
affected by loss of power to the unit.
ADSL2+ Plus POTS Interface
Each ADSL2+ plus POTS interface provides transport for standard POTS from the Central
Office (CO) to the customer. The frequency ranges for Total Access 1224 deployment are as
follows:
• POTS accommodates frequency ranges up to 4 kHz
• ADSL and ADSL2 accommodates frequency ranges up to 1.1 MHz
• ADSL2+ accommodates frequency ranges up to 2.2 MHz
Any analog devices connected to this interface must use a low-pass filter to prevent high
frequencies from interfering with the device.
