3. CONNECTIONS
The Total Access 3000 H2TU-C occupies one card slot
in a Total Access 3000 Shelf. Power and alarm signals
are provided to the card through the backplane of the
shelf. DSX1 and HDSL2 loop signals are connected to
the backplane on pins or mass termination shelf
connectors (amphenol) corresponding to the slot the
unit occupies. See Figure 3 for H2TU-C edge
connection wiring.
The Total Access 3000 shelf delivers DSX-1 from the
network to the H2TU-C via connectors on the
backplane labeled “Pair 7” and “Pair 8”. The HDSL2
signal is provided toward the customer via the
backplane connector labeled “Pair 2”. Pins 1 and 33 of
the connectors Pair 7 and Pair 8 are the DSX connec-
tions for the H2TU-C in Slot 1. Pins 2 and 34 of these
connectors are associated with Slot 2. Pins 3 and 35 are
associated with Slot 3, and so forth, up to pins 28 and 60
for Slot 28.
