POTS Connection
The Total Access 1248 must be connected to a POTS source to provide POTS to the
subscribers. 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 connectors
labeled
POTS
. There is a one-to-one correlation between the pins on the POTS amphenol
connectors and the pins on the ADSL2+ plus POTS (
ADSL + POTS
) amphenol connectors. Refer
to the
“Customer Connections (ADSL2+ PLUS 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 amphenol
connectors provided, labeled
POTS
.
2. Tighten the screw (normally provided with each amphenol connector attached to the
cable) on the right side of each amphenol connector, and use the cable ties (provided)
threaded through the tie-down brackets (provided) to secure the left side of the amphenol
connectors.
NOTE
This wire tie may be used to assist in routing the power cables and
the ADSL+POTS cables that originate from the right most amphe-
nol connector.
NOTE
The POTS interface may be connected to the outside plant.
Customer Connections (ADSL2+ PLUS POTS)
The Total Access 1248 provides 48 ADSL2+ plus POTS ports on two 50-pin male amphenol
connectors. POTS is brought in from the CO on the POTS amphenol connectors as described
in the preceding section. The ADSL2+ is generated locally and placed on the same pair as the
corresponding POTS signal for delivery to the subscriber.
There is a one-to-one correlation between the pins on the ADSL2+ plus POTS amphenol
connectors and the pins on the POTS amphenol connectors. Refer to the
section above for more information. The 25th pair is not used. To establish the ADSL2+ plus
POTS connection, perform the following steps:
1. Connect the 25-pair female amphenol connectors to the male amphenol connectors pro-
vided, labeled
ADSL + POTS
.
2. Tighten the screw (normally provided with each amphenol connector attached to the
cable) on the right side of each amphenol connector, and use the cable ties (provided)
threaded through the tie-down brackets (provided) to secure the left side of the amphenol
connectors.
The pin assignments for the left and right POTS and ADSL2+ plus POTS cables are shown
