UL Deployment Guidelines
• Terminate enclosure to a reliable ground source.
• This unit shall be installed in accordance with the
requirements of NEC NFPA 70.
ADSL and POTS Connection
One 25-pair termination block provides the
interconnect wiring for the access modules located in
slots 1 through 6 of the enclosure. When using the
Quad ADSL plus POTS Access Module, the POTS
signal is provided by the network and is connected to
certain pairs on the Total Access 1000 DAT
termination block. The ADSL plus POTS signal is
then delivered to the customer by other pairs on the
termination block. See
Table 2
for pair assignments.
