In a standard configuration, the POTS will be brought in from a nearby cross-connect. The Total Access 1248 accepts the POTS signal on the top two amphenol connectorslabeled POTS. There is a one-to-one correlation between the pins on the POTS amphenolconnectors and the pins on the ADSL plus POTS (ADSL+POTS) amphenol connectors. Refer tothe “Customer Connections (ADSL+POTS)” section below for more information.To establish a POTS connection, perform the following steps:1. Connect the cables with the 25-pair female amphenol connectors to the male amphenolconnectors provided, labeled POTS.2.
