Input/Output
Connections
Basic FrameSaver NP 64+ has input/output connectors for the DDS facility, Data Port
(DTE), two AUX ports, and Modem Line. Pinouts for each of these ports are provided
in the tables that follow.
NOTE: Refer to Section 6, “Options” of this manual for a description of additional
connectors with options such as the ISDN Adapter or Second DSU.
CAUTION
The installer must ensure that the plugs used to connect
the DDS Line to the FrameSaver NP 64+ are “keyed”
modular plugs that match the connectors. This will
prevent the accidental connection of the DDS Line to
either of the FrameSaver NP 64+ AUX connectors.
DDS Connection
Use cable assembly # 135-982-0006, or per pinout shown in Table 3-2.
Data Port Interface
& Cable Code
The Data Port (DTE) supports five electrical interface types; ITU-V.35, EIA-530,
EIA-530-A, ITU-X.21-NS, and EIA-232. The Data Port connector on the back of the
FrameSaver NP 64+ is a DB-44 high density female. A short (approx. 2.5 ft.) adapter
cable is used to convert from the DB-44 to the appropriate connector type for the in-
terface selected. The adapter cable also includes a unique Cable Code (CBC), a special
wiring pattern at the DB-44 connector, which automatically sets the port to the desired
interface type.
NOTE: Some manufacturer specific cable pinouts are provided at the end of this man-
ual section, under General Specifications.
