Safety Instructions  
When using your telephone equipment, please follow these basic safety precautions to reduce the risk  
of fire, electrical shock, or personal injury:  
1. Do not use this product near water, such as a bathtub, wash bowl, kitchen sink, laundry tub, in  
a wet basement, or near a swimming pool.  
2. Avoid using a telephone (other than a cordless-type) during an electrical storm. There is a  
remote risk of shock from lightning.  
3. Do not use the telephone to report a gas leak in the vicinity of the leak.  
4. Use only the power cord, power supply, and/or batteries indicated in the manual. Do not  
dispose of batteries in a fire. They may explode. Check with local codes for special disposal  
instructions.

Affidavit Requirements for Connection to Digital Services  
An affidavit is required to be given to the telephone company whenever digital terminal equipment  
without encoded analog content and billing protection is used to transmit digital signals containing  
encoded analog content which are intended for eventual conversion into voiceband analog signals  
and transmitted on the network.  
The affidavit shall affirm that either no encoded analog content or billing information is being  
transmitted or that the output of the device meets Part 68 encoded analog content or billing  
protection specifications.  
End user/customer will be responsible for filing an affidavit with the local exchange carrier when  
connecting unprotected customer premise equipment (CPE) to 1.544 Mbps or subrate digital  
services.  
Until such time as subrate digital terminal equipment is registered for voice applications, the affidavit  
requirement for subrate services is waived.

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.

Chapter 1. Introduction  
When combined with the supported ATLAS 800 Series base units and,  
optionally, one or more Quad T1/PRI or T3 Modules, the NxT1 HSSI/V.35  
Module can implement high-speed point-to-point connectivity), combining  
multiple T1 circuits into one logical channel on the HSSI/V.35 interface.

supported ATLAS 800 Series units. You can view the status of the module  
itself, as well as the circuits to which it interfaces, from the front panel  
(ATLAS 800PLUS only). Additional status information is available via the  
terminal menus, accessible through either a VT-100 terminal connected to  
the ATLAS 800 Series control port, or via a Telnet session established  
through the unit’s Ethernet port. Use the terminal menu to configure the  
NxT1 HSSI/V.35 Module and to download application software.

POWER UP AND INITIALIZATION  
The NxT1 HSSI/V.35 Module requires no initialization input during the  
power-up sequence, as described in the ATLAS 800 Series User Manuals.  
Any previously configured setting for the NxT1 HSSI/V.35 Module is auto-  
matically restored upon power-up.  
Failed Self-Test  
If the NxT1 HSSI/V.35 Module fails self-test, a message will be displayed  
on the LCD and the terminal menu self-test log during power-up. See the  
appropriate ATLAS 800 Series User Manual for details.  
Operation Alarms  
The red ALARM LED (located with the Module LEDs on the front panel)  
illuminates when an alarm condition is detected.

Operation  
OVERVIEW  
You can control and configure the NxT1 HSSI/V.35 Module from a variety  
of sources, including the following:  
The ATLAS 800 Series front panel, providing minimal configuration  
and status support  
The terminal menus, allowing detailed configuration, status, and diag-  
nostics  
SNMP, primarily for reporting alarm conditions and system status  
The remainder of this section describes the menu items presented when man-  
aging the NxT1 HSSI/V.35 Module via the terminal menu.  
Access the terminal menu using either a VT-100 terminal attached to the  
ATLAS 800 Series Base Unit’s control port or a Telnet session established  
through the Base Unit’s Ethernet port. The ATLAS 800 Series User Manual  
provides detailed instructions on the operation of each of these management  
approaches.  
To edit items in the terminal menu, you must have the appropriate password level. Each menu  
description in this section indicates the password level required for write and read access. See  
“Access Passwords” in the appropriate ATLAS 800 Series User Manual for detailed  
information on working with passwords. Security level 0 users can view and edit every available  
field. Security level 5 users can view any field but cannot edit.  
TERMINAL MENU STRUCTURE  
ATLAS 800 Series uses a hierarchical menu structure to provide access to  
all of its features. The top-most menu level leads to submenus which are  
grouped by functionality. All menu items display in the terminal window. To  
access the NxT1 HSSI/V.35 Module, activate the MODULES menu. The fol-  
lowing sections describe the menu items for the MODULES menu.  
Refer to the appropriate ATLAS 800 Series User Manual for detailed instructions on  
navigating through the terminal menu.

TX CLOCK  
Controls the clock used by the NxT1 HSSI/V.35 Module to accept  
the transmit (TX) data from the DTE. This is usually set to Normal.  
If the interface cable is long, causing a phase shift in the data, the  
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.

FACTORY  
RESTORE  
You can restore the factory default settings for an NxT1 HSSI/V.35 Module

particular field).  
RUN SELFTEST  
RUN SELFTEST, a submenu of the ATLAS 800 Series main menu item TEST,  
executes both the NxT1 HSSI/V.35 Module internal test and the ATLAS 800  
Series internal test. For additional information on RUN SELFTEST, see the AT-

T1 TROUBLE CODE SERVICE  
Sets known values in the signaling bits and the data field for outgo-  
ing DS0s which are cross-connected to a T1 port experiencing  
alarms.  
The trunk conditioning process consists of a 2.5 second transmis-  
sion (indicating call termination), followed by a continuous trans-  
mission signaling the final condition as chosen by the user. This  
selection is only valid for T1 ports having RBS set to ON.  
This option defines to the NxT1 HSSI/V.35 Module the type of sig-  
naling being used on the trunk: E&M, LS/GS Network or User,  
SW56, or Custom.  
T1 TROUBLE CODE VALUE  
Displays the Hex value of the 2.5 second pre alarm transmission.
