Figure 2. Point-to-Point Deployment
The TA 750 Power Supply Unit (PSU) and Bank
Controller Unit (BCU) common modules provide both
power and provisioning for the Nx56/64. Provisioning
is screen menu driven via a DB-9 VT 100 interface on
the BCU. All wiring connections are built into the
TA 750 chassis backplane. External wiring
connections are not required.
Signal transmission of the Nx56/64 is through the
V.35 port on the TA 750 chassis backplane. For those
installations equipped with an RS-449 connection, a
V.35 to RS-449 adapter cable pinout is shown in
Table 1.
