ADTRAN Dual Nx56/64 Instruction Manual

CLEI: VAL4NS0D_ _
Product P/N: 1180025L1
DESCRIPTION
The Total Access 1500 Dual Nx56/64 is a DSU data
port with two circuits that each deliver T1 data over
a V.35 interface. The unit is designed specifically for
the Total Access 1500 chassis. Each circuit of the
Dual Nx56/64 can be craft provisioned to provide
up to 24 channels in increments of N=56 or 64k, or
one channel. Design operation is to transmit or
receive high rate synchronous data from data
terminal equipment (DTE) over T1. Transmission
data rates for each circuit of the Dual Nx56/64
range from 56 kbps to 1.536 Mbps using noncon-
tiguous bandwidth assignment. The Dual Nx56/64
features:

– DSR follows DTR
– DSR forced on and DTR ignored
– CTS follows RTS
– CTS forced on and RTS ignored
– DCD active when loops in sync and/or
T1 carrier present
– Causes DCD to be forced on always
– Measures the delay between the DTE data
and its clock and automatically selects
between Internal and INT-INV
– Allows the Nx56/64 to provide transmit
data clock
– Derives DTE transmit clock from the DTE
device
– Inverted form of the DTE TX CLK setting

INSTALLATION
After unpacking the Dual Nx56/64, inspect it for damage.
If damage is noted, file a claim with the carrier and then
contact ADTRAN. For more information, refer to the
warranty.

of the Total Access 1500 chassis. To insert, hold the
Dual Nx56/64 by the faceplate while supporting the
bottom edge of the card. Align the card edge with the
guide grooves in the first of the two consecutive slots
chosen to install the card in. Insert into chassis until
the edge connector seats firmly into the chassis back-
plane. Lock the unit in place by pushing in on the
locking lever.
