Introduction  
NXT1 HSSI/V.35 MODULE OVERVIEW  
The NxT1 HSSI/V.35 Module is a member of the ATLAS 800 family of  
integrated access products that supports aggregating point-to-point T1  
bandwidth (from 2 to 8 T1s) to a single logical datastream available on the  
high speed serial interface (HSSI) of the module. The HSSI interface is  
delivered using a standard 50-pin SCSI-II connector. Alternately, an optional  
adapter cable may be purchased (ADTRAN P/N 3125I081) to convert the  
HSSI interface to a single V.35 interface when needed. When using the  
NxT1 HSSI/V.35 Module in a V.35 configuration, up to 4 T1s of aggregated  
bandwidth is supported.  
The inverse multiplexing capacity of the module accommodates eight  
T1s, and the module automatically adjusts the data rate to the HSSI/V.35  
port upon loss of one or more T1 circuits. In addition to the HSSI port,  
four T1 ports are included on the module itself, while alternate T1 ports  
can be provided using other ATLAS 800 T1 or T3 modules. The  
NxT1 HSSI/V.35 Module combines with the ATLAS 800 Series base  
units (ATLAS 800PLUS and ATLAS 890 only) and other ATLAS modules to  
support applications calling for increased point-to-point T1 bandwidth.  
Figure 1-1 shows a sample application of the NxT1 HSSI/V.35 Module.

clock can be set to Inverted. This switches the phase of the clock,  
which compensates for a long cable.  
CA  
(Not applicable in V.35 mode.)  
Asserts the data Communications equipment Available signal from  
the DCE. CA will be asserted by the DCE, independently of TA,  
when the DCE is prepared to both send and receive data to and  
from the DTE. This indicates that the DCE has obtained a valid data  
communications channel. Data transmission should not commence  
until TA has also been asserted by the DTE.  
LC  
(Not applicable in V.35 mode.)  
Enables the Loopback Circuit C signal from the DCE. LC is an  
optional loopback request signal from the DCE to the DTE,  
requesting the DTE provide a loopback path to the DCE.
