Introduction
SECOND GENERATION (2ND GEN) NX56/64 V .35 OPTION
MODULE OVERVIEW
The Second Generation (2nd GEN) Nx56/64 V.35
option module is one of the option modules available for
use with the following ADTRAN equipment:
• TSU 100 (part number 1200052L1)
• TSU 600 (part number 1200076L1)
• TSU 120 (part number 1200129L1)
• HSU 100 (part number 1200097L1)
• HSU 600 (part number 1200098L1)
The 2nd GEN Nx56/64 V.35 option module installs in
the option slot of the TSU/HSU family of products and
provides an additional synchronous V.35 interface port.
When used in these products, this interface port allows
an additional DTE to have access to the T1 service.
2ND GEN NX56/64 V .35 PLUG-ON BOARD OVERVIEW
The operations of the 2nd GEN Nx56/64 V.35 option
module described in this manual are also applicable for
the 2nd GEN Nx56/64 V.35 plug-on board. Operation
of both is identical except for the physical installation.

THE FUNCTIONAL DESCRIPTION OF THE 2ND GEN NX56/
64 V .35 OPTION MODULE AND PLUG-ON BOARD
The 2nd GEN Nx56/64 V.35 option module operates in
the option slot of the TSU/HSU products while the plugon board operates as a plug-on to any option module.
Both are under the control of the TSU/HSU 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/HSU
product.

Physical Description
The 2nd GEN Nx56/64 V.35 option module plugs into
the option slot in the rear of the TSU/HSU 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 2nd GEN Nx56/64 V.35 plug-on board (or any
other plug-on board) to be added to the 2nd GEN
Nx56/64 option module creating a multiport module.
The PORT X.1 and X.2 indication is linked to the port
numbering philosophy of the TSU/HSU product family.
The X represents the slot number, into which the option
module is plugged. For the TSU 100 there is only one
option slot. Therefore the port designation would be 1.1
and, if a plug-on V.35 is present, port 1.2. In a TSU 600
with six option slots, these port numbers would be port
1.1 to port 6.1. The numbers appear in the front panel
LCD menu displays.

Power-Up T esting and Initialization
The option module executes a self test during the
power-up sequence, as described in the TSU/HSU
manual. No initialization input is required. Upon
power-up, any previously configured setting for the
option module is automatically restored.
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 On. For more
information, see the section that discusses front panel
operation in the Operation chapter of the appropriate
TSU/HSU user manual. If any alarms are detected
during operation, the red LED labeled ALARM in the
MODULE group on the front panel turns On.

Port Configuration Submenu
To select Port Configuration, press the Enter key. This
displays the first of eight submenu items. They are
defined as follows:
1)INTERFACE
This selects the active interface for the Base Nx port.
The Nx ports, which are installed as option modules,
have only one type of interface.
Choice - V.35
2)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
port. The DTE data rate versus the number of DS0s
appear in the appendix DTE Data Rate Chart of the TSU
100 User Manual.
Choices - 56K or 64K
3)TX CLK
Controls the clock used by the TSU 100 to accept the
transmit (TX) data from the DTE. Normally this is set to
Normal. If the interface cable is long, causing a phase
shift in the data, the clock can be selected as Inverted.
This switches the phase of the clock which should
compensate for a long cable.
Choices - Normal or Inverted
4)DAT A
Used to control the inverting of the DTE data. This
inversion can be useful when operating with a high-level
data link control (HDLC) protocol (often used as a
means to ensure 1s density).
Choices - Normal or Invert
18 2nd GEN Nx56/64 Option Module User Manual 61202.054L1-1
Chapter 3. Operation
5)CTS
Used to control characteristics of CTS.
Choices - Normal or Force On (see Table 3-A).
6)DCD
Data Carrier Detect - Indicates to the DTE when a
valid signal is being received at the Network Interface.
Choices - Normal or Force On (see Table 3-A).
7)DSR
Data Set Ready - This signal indicates to the DTE when
the DCE is turned On and ready for operation.
Choices - Normal or Force On (see Table 3-A).
8)0 INHIB
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 or Off

Chapter 3. Operation
9)INBAND (Inband Configuration Channel)
Used to enable/disable an 8 kbps remote configuration
channel (see Figure 3-5). 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.
This 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.
The menu option can also be set to On-Demand which
will activate the Inband Channel only when commands
are sent from T-Watch to the remote unit (TSU 600 B in
Figure 3-5). If no T-Watch activity is detected for 10
minutes, the Inband Channel is deactivated.

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.

2)RUN SELF TEST , Submenu of 4)TEST
This menu item is used to execute both the internal test
of the TSU/HSU and of the 2nd GEN Nx56/64. This is
the same test executed during power-up. The results of
the self test are shown on the TSU 100 display. For
additional information on self test, see the chapter
Operation in the appropriate TSU/HSU user manual.
To activate a self test, do the following:
1. Follow the standard operating procedure to access
the 4)TEST menu items.
2. With the cursor on 2)RUN SELFTEST, press the
Enter key. This results in a changing TSU/HSU
display, showing the test outcome.

3)PORT TEST , Submenu of 4)TEST
This menu item is used to activate testing of specific
data ports. It also controls the activation of loopbacks
and the initiation of data test patterns. Test results are
shown on the TSU/HSU display.
The execution of Port Tests disrupts normal data flow in the
port being tested.
Operation
To display Figure 3-8 on the TSU 100, starting with the
cursor on 3)PORT TEST, press the Enter or number 3
key. This displays the available ports.

Port Test Submenu
1.1 2nd GEN Nx56/64: The Nx interface offers the
following test functions:
1) LOOPBK
Initiates a loopback.
PRT/LCL The Nx port activates both a local
loopback (back toward the DTE) and a
port loopback when either is invoked.
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.
OFF The loop is deactivated.
61202.054L1-1 2nd GEN Nx56/64 Option Module User Manual 23
Chapter 3. Operation
The TSU/HSU checks the remote loopback activation by
detecting 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.
2)511 PATT
Activates the generation of the 511 test pattern.
ON The pattern check circuitry is enabled
and a test started. The test is ended by
selecting OFF.
OFF The pattern generation and check is
disabled.
3)DIS 511 RESLT
Displays the results of the 511 test indicated in 2)511
PATT. The results are in the form of the number of
errored seconds. The error count can be cleared by
pressing the Clear key (Shift + 9). A bit error may be
inserted into the data stream by pressing the 2 key.
