POTS Connection
The Total Access 1224 must be connected to a POTS source to provide POTS to the customers.
In a standard configuration, the POTS will be brought in from a nearby cross-connect. The
Total Access 1224 accepts the POTS signal on the amphenol connector labeled POTS PORTS
1-24. There is a one-to-one correlation between the pins on the POTS amphenol connector and
the pins on the ADSL2+ plus POTS (ADSL + POTS PORTS 1-24) amphenol connector. 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 cable with the 25-pair female amphenol connector to the male amphenol con-
nector provided, labeled POTS PORTS 1-24.
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 1224 provides 24 ADSL2+ plus POTS ports on one 50-pin male amphenol
connector. POTS is brought in from the CO on the POTS amphenol connector 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 customer.
There is a one-to-one correlation between the pins on the ADSL2+ plus POTS amphenol
connector and the pins on the POTS amphenol connector. Refer to the “POTS Connection”
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 connector to the male amphenol connector pro-
vided, labeled ADSL + POTS PORTS 1-24.
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
in Table 3-5.
