DUAL NX56/64 V.35 OPTION MODULE OVERVIEW
The Dual Nx56/6 4 V.35 option module is one of the option modules available for use with the following ADTRAN equipment:
• TSU 100e
• TSU 600e
• TSU 610
• TSU 120e
• TDU 120e
• ESU 120e
The Dual Nx56/64 V.35 option module installs in the op-
tion slot of the TSU/TDU/ESU family of products and
provides two additional synchronous V.35 interface
ports. When used in these products, this interface port allows two additional DTEs to have access to the T1 service.
DUAL NX56/64 V.35 PLUG-ON BOARD OVERVIEW
The operations of the Dual Nx56/64 V.35 option module
described in this manual are also applicable for the Dual
Nx56/64 V.35 plug-on board. Operation of both is identical except for the physical installation.

Chapter 1. Introduction
Dual Nx56/64 V.35 Option Module and Plug-on Board Description
The Dual Nx56/64 V.35 option module operates in the
option slot of the TSU/TDU/ESU products, while the
plug-on board operates as a plug-on to any option module. Both are under the control of the TSU/TDU/ESU
product. The option module and the plug-on board are
configured from the front panel or by an external PC program. The internal menus for their configuration are part
of the option module and plug-on board and are automatically installed when either is plugged into a TSU/TDU /
ESU product.
Features of the Dual Nx56/64 V.35 Option Module
• Operates using one to twenty-four DS0s (32 in E1).
• Includes an elastic store for absorption of rate variations
• Outputs a 50 percent duty-cycle output clock at all
rates
• Menu operation for easy configuration
• Executes and responds to V.54 looping codes
• Generates and checks a 511 test pattern
• Performs an extensive self-test
• Supports multiport dial backup operation
• Provides inband channel ne tw ork management c om munication

Physical Description
The Dual Nx56/64 V.35 option modu le plug s in to the o ption slot in the rear of the TSU/TDU/ESU family of products (see Figure 1-1).
The rear panel of the option module includes a plastic
plug over a cutout for a second V.35 connector. This allows a Dual Nx56/64 V.35 plug-on board (or any other
plug-on board) to be added to the Dual Nx56/64 option
module, creating a multiport module. The

UNPACK & INSPECT
Carefully inspect the option module or plug-on board for
any shipping damage. If damage is suspected, file a claim
immediately with the carrier and then contact ADTRAN
Customer and Product Service (CAPS). If possible, keep
the original shipping container for use in shipping the option module or plug-on board back for repair or for verification of damage during shipment. See product support
information on the back page of this manual for information on how to contact ADTRAN.

Power Connection
Each option module derives power from the base TSU/
TDU/ESU unit. Power to the base unit is supplied by a
captive eight-foot power cord.
Attaching the Plug-On Board
Figure 2-2 shows the proper attachment of a plug-on
board to the option module. Perform the following steps
to install the plug-on board:
1. Hold the plug-on board above the option module.
2. Using a downward and right-to-left motion, slip the
plug-on board connector into opening in the option
module back panel.
3. Moving the plug-on board downward, secure the
connection of the header pins at the front of the
boards.
4. Install two 4-40 screws at both front edges of the
option module.
5. Install two 4-40 screws o n each of the standoffs on
the rear of the plug-on module.

Power-Up Testing and Initialization
The option module executes a self-test during the powerup sequence, as described in the TSU/TDU/ESU manual
of the base unit. No initialization input is required. Upon
power-up, any previously configured setting for the option module is automatically restored unless the software
has changed revision.
When the self-testing is completed and the configuration
is successfully restored, the LED labeled OK in the module group on the front panel turns

Rate 56/64
This sets the base rate of the interface. The actual data
rate depends on the number of DS0s assigned to the Nx

Choices: 56K or 64K
Transmit Clock (TX CLK)
Controls the clock used by the TSU 100 to accept the
transmit (TX) data from the DTE. This is usually s et to

phase-shift in the data, the clock can be selected as

. This switches the phase of the clock, which
should compensate for a long cable.
Choices: Normal; Inverted
Data
Used to control the inverting of the DTE data. This
inversion can be useful when operating with a high level
data link (HDLC) protocol. Often used as a means to
ensure 1s density.
Choices: Normal or Inverted

If the Nx interface detects an uninterrupted string of 0s
being transmitted toward the network, and if 0s are
transmitted for more than one second, then the TSU 100
forces 1s towards the network.
Choices: On; Off
INBAND
Inband Configuration Channel - Used to enable/disable
an 8 kbps remote configuration channel (see Figure 3-5
on page 3-9). When this option is set to ON, the first DS0
mapped to the Nx interface operates in 56K mode and
the DTE clock rate is reduced by 8 kbps. The TSU/HSU
uses this 8 kbps channel to send and receive configuration data across a T1 span. As shown in Figure 3-5, this
allows the PC connected to the chain-in port on TSU 600
A to monitor/configure both TSU 600 A and B. This feature is useful when FDL connectivity is not available
across the T1 span.
ALARM
The 8 kbps channel is only taken out of the first DS0. If
two 64K DS0s are mapped, the DTE rate would be 120
kbps instead of 128 kbps.

Although a router can accommodate this 8K rate reduction, some DTE
devices may not (i.e., video). Determination should be made if the
connected DTE can handle this reduced clock source. A second option
would be to operate in 56K/DS0.

The Nx interface offers the following test functions:
LOOPBK
Initiates a loopback.
PRT/LCI
The Nx port activates both a local loopback (Back toward
the DTE) and a port loopback when either is invoked
3-12 Dual Nx56/64 Option Module User Manual 61200142L1-1
Chapter 3. Operation
REMOTE
The remote loopback causes a V.54 code to be sent to the
far end. The Nx at the far end activates a PORT/LCL
loopback on detection of the V.54 code.
REM V.54 CONT
This loopback causes continuous V.54 code to be sent to
the far end. The Nx at the far end activates a
PORT/LCL
loopback upon detection of the V.54 code.
OFF
The loop is deactivated.
The TSU/TDU/ESU checks the remote loopback act ivation by det ecting a
proper response from the remote end. While waiting for the response, the
display shows Looping. If successful, the display changes to Looped
Up. If unsuccessful, the display shows Failed.
511 PATT
