INITIALIZATION
Set User Passcode
The TDU 120e is designed to operate with or without the
use of a passcode. The default condition is without a pass-
code.
If the unit is to be remotely accessed using T-Watch PRO, you must enter
a passcode. When managing a number of units, the passcode can be the
same for all the units.
The passcode should be a number easily remembered.
Once entered, the passcode is required to access any op-
eration other than viewing. See Set Passcode on page 6-3
for details.
Set Unit Identification
The UNIT ID sets the unit to respond to remote control
(controlled by a device other than the front panel or ter-
minal). If no Unit ID is recorded it is not possible to oper-
ate from any remote control device, including the local PC
for T-Watch PRO or SNMP. See Unit ID on page 6-3 for
details.
Set Control Port
The TDU 120e can be configured from the control port
when T-Watch PRO, SNMP, or the terminal interface are
being used. If the control port is to be used, the control
port baud rate must also be selected.

to identify the data port the menu item is referencing. If a
module containing a PBX DSX-1 option card with an
Nx56/64 plug-on interface is installed in the option slot,
it would be designated as:
DSX-1 Passthru (1.1)
Where slot=1 and port=1.
The DSX-1 is located in the option slot and is the first port
in that slot.
Nx56/64 (1.2)
Where slot=1 and port=2.

provides complete control over the configuration of the
TDU 120e using a graphical interface. The T-Watch PRO
program displays the same status and performance data
as the terminal screen. This data is displayed in tables and
graphs.
The T-Watch PRO program has the following capabilities:
•
Interfaces with a modem which permits dialing into a
remote TDU 120e location to configure the unit or
read the status or performance of the unit.
•
•
Receives traps from any TSU product.
Records and creates display performance data over a
30-day period.
•
Accesses units via the local area network (LAN).

Normal (CSU) Timing
The typical timing option arrangement is shown in
Figure 5-9. The PBX is looped timed sending data to
the TDU 120e which is actually synchronous to the
received data. The Network Interface (NI) is the
actual source of all timings. This timing option is the
same as that typically used for CSUs. It works
equally well when the PBX is the source of timing. In
that configuration the network would not be provid-
ing timing.

Reviewing Maps
Selections 4 through 6 give a summary of the number of
ports assigned to Map A, Map B, and the Temp map,
respectively. The menu items and their descriptions fol-
low:
Copy Map A (B) to Temp Map
Copies the current map A (B) into a TEMP map area.
This permits modification without disturbing the
existing map. When the modifications are com-
pleted, the TEMP map is written to current MAP A
(B) by selecting APPLY TEMP MAP TO MAP A (B).
Create Temp Map
Creates a map by defining a port or Idle for all DS0s.
When CREATE TEMP MAP is first selected, all DS0s
are set to Idle.
Possible port selections include IDLE, TST, + option
module ports.
TST designates which DS0s are used for QRSS test-
ing when activated under the TEST menu.
When not used for testing, the TST designation is
identical to IDLE.

The CONFIG menus for options ports are described in sep-
arate sections of the manual supplied with the option
card.
Nx/DBU (0.1) Menu Items
The Nx/DBU port has two main menus:
NX56/64 CONFIG -- Nx operation and DBU CONFIG -- DBU
operation.
Nx56/64 Config
Under NX56/64 CONFIG, the menu items are:
DS0 RATE
This sets the base DS0 rate of the interface. The actual
data rate depends on the number of DS0s assigned to
the Nx port.
Choices: 56K OR 64K
TX CLK CNTRL
Controls the clock used by the TDU 120e to accept
transmit (TX) data from the DTE. The default is
NORMAL. If the interface cable is long, causing a
phase shift in the data, the clock can be selected as
INVERT. This switches the phase of the clock which
should compensate for a long cable.
Choices: NORMAL, INVERT
DATA
Used to control the inverting of the DTE data. This
inversion can be useful when operating with an
HDLC protocol. Often used as a means to ensure 1s
density.
Choices: NORMAL or INVERT
If INVERT is selected, zero (0) inhibit should also be selected to prevent an
open DTE input from placing zeros on the network.

DCD
Data Carrier Detect. Indicates to the DTE when a
valid signal is being received at the Network Inter-
face.
Choices: NORMAL (see Table 5-1 on page 5-25) or

DSR
Data Set Ready. This signal indicates to the DTE
when the DCE is turned on and ready for operations.
Choices: NORMAL (see Table 5-1 on page 5-25) or
FORCE ON
“0” INHIB
The Nx interface will detect an uninterrupted string
of zeros (0s) being transmitted toward the network.
If 0s are transmitted for more than 1 second, the TDU
120e will force 1s.
Choices: ON or OFF
INBAND MODE
The Nx56/64 port is capable of providing an inband
communications channel (for T-Watch PRO and
SNMP) between units. This is accomplished by using
8 kbps of the first DS0 assigned to that particular
Nx56/64 port. If in 56K mode, no data bandwidth
will be used. Inband must also be enabled at the des-
tination port.
Choices: ON or OFF, ON DEMAND
TX CLK SOURCE
Controls the source of the clock used by the TDU
120e to accept transmit data from the DTE. The
default option is INTERNAL.
If the application requires that the DTE device pro-
vide the clock with the transmit data, the External
setting is used.

Test Patterns
All Ones
Sends an all ones pattern to the network.
All Zeros
Sends an all zeros pattern to the network.
QRSS Pattern
The QRSS pattern is commonly used to simulate real
data in T1 interfaces. This pattern can be assigned to
appear in all DS0s or only in TST DS0S. When QRSS is
set in all DS0s and one of the network loopbacks previ-
ously described is activated at the far end, a total end-to-
end integrity check can be run without the need for any
external test equipment.
When QRSS is assigned to TST DS0S, an integrity check
of the link can be run along with normal data flow. The
TST DS0S are user assigned as part of the DS0 Map.
This sets the pattern for the test and initiates the trans-
mission of the pattern. The test is terminated by selecting
NONE.
The following patterns are available:
QRSS All DS0s
Generates a QRSS test pattern and inserts the pattern into
all DS0s.

UNIT ACCESS TABLE
This menu edits/creates the Unit Access Table and stores
the Unit ID, Passcode, and Unit Type for units connected
via chain ports or connected remotely to the TSU/TDU
(see Figure 8-1).
An entry in the table is required only to support proxy
SNMP MIB access or polling. For MIB access, an entry is
required only if the unit's passcode is not the same as the
DEFAULT UNIT PASSCODE, or the unit is a single port TSU
Standalone.
It is not necessary to have an entry in this table for a remote unit in order
to Telnet to it or forward SNMP traps from it. In the Telnet case, the
Remote Menu Access menu is selected from the Main menu and a unit
ID is entered which may or may not be in the Unit Access Table.
Units accessed via T-Watch PRO over TCP/IP use the
unit ID and passcode set by T-Watch PRO running on the
PC.

Add New Unit
You must enter a device Unit ID, passcode, Unit type, and polled
flag. Unit type can be:
Standard (which supports any TSU/TDU Multiplexer and the ISU
512), or TSU Standalone (a single port TSU with no option card slot).
A passcode of 0 to 9999 for each device or DEFAULT may be
selected, which results in the default passcode being used (defined
as 0022 in Figure 8-1 on page 8-2).
Traps are normally sent from the unit in alarm to the TDU 120e. For
units in the Unit Access Table that are not chained directly to the
TDU 120e but are managed over Inband or the FDL, traps are not
automatically forwarded. Polling must be enabled on the TDU 120e
for these units in order to receive Traps on the NMS. The TDU 120e
can be configured to poll selected units for traps by enabling the
polled option when adding or modifying a unit entry.
Allows unit ID, passcode, device type, and polled flag to be changed
for an existing entry in the table.

Appendix A Understanding SNMP
WHAT IS SNMP?
The term SNMP broadly refers to the message protocols
used to exchange information between the network and
the managed devices, as well as to the structure of net-
work management databases.
SNMP came about as local area network (LAN) environ-
ments became standardized over the past ten years and
multi-vendor equipment grew with competition. It be-
came necessary to manage the various vendor equipment
from a single control console. Thus, the SNMP emerged
as the standard for managing commercial TCP/IP net-
works.
Basic Components of SNMP
SNMP has three basic components: Network Manager,
Agent, and MIB.
Network Manager
This is a control program that collects, controls, and pre-
sents data pertinent to the operation of the network
devices. It resides on a network management station.
Agent
This is a control program that responds to queries and
commands from the network manager and returns
requested information or invokes configuration changes
initiated by the manager. It resides in each network
device.
61202156L2-1
TDU 120e User Manual
A-1
Appendix A. Understanding SNMP
MIB
This is an index to the organized data within a network
device. It defines the operating parameters that can be
controlled or monitored. When requesting the network
manager to retrieve or modify a particular piece of infor-
mation about a network device, the network manager
transmits the request to that network device. The agent
in that device interprets the incoming request, performs
the requested task, and sends its response to the network
manager. The network manager collects all the data from
the various network devices and presents it in a consis-
tent form.
Commands
Using SNMP Version 1, the network manager can issue
three types of commands:
GetRequest
Retrieves a single item or the first in a series from a net-
work device.
GetNextRequest
Retrieves the next item in a series from a network device.
SetRequest
Writes information to a network device.
A-2
TDU 120e User Manual
61202156L2-1
Appendix A. Understanding SNMP
Message
The network device issues two types of messages:
GetResponse
The response to a network manager GETREQUEST or
GETNEXTREQUEST command.
Trap
An unsolicited message issued by a network device to
report an operational anomaly or an alarm condition to
the network manager.
These messages are typically encased within informa-
tional packets and transported over the LAN or WAN
(wide area network).

TDU 120e SNMP Access
By default, SNMP MIB Browser access to the TDU 120e IP
address with the configured community names, accesses
the host. The TDU 120e can also act as an SNMP proxy
agent for external units.
To access MIB variables on externally chained devices,
append a period and the Unit ID of the device to the Read
and Read/Write community names.
Example:
If...
Then...

variables from externally chained

However, SNMP traps for the unit
can be forwarded without the entry.

TDU 120e User Manual
61202156L2-1
Appendix A. Understanding SNMP
SNMP Trap Configuration
Traps received by the TDU 120e from external units and
the host unit are converted into SNMP traps and forward-
ed to the configured NMS. The source of the trap is
uniquely identified at the NMS by a combination of the IP
address of the TDU 120e, and the Unit ID of the sending
device. The Unit ID is present in the trap packet append-
ed to the end of the trap community packet name, for ex-
ample public.4. It is also included as an Octet String
variable (adProdPhysAddress) in the trap packet as de-
fined in the individual product MIBs. The latest versions
of the product MIBs, by default, display the appended
trap community name in their descriptions.
Typical steps required for Management Station trap con-
figuration are:
1. loading the device specific MIBs, and
2. loading or creating device-specific Trap Definition
Files.
The current product MIBs contain keywords embedded
in comments that can be used by some network manage-
ment platforms to automatically generate Trap Defini-
tions. Otherwise, the descriptions may be used as a
template for Trap Definitions.
If individual option card port and slot identification is re-
quired, it is present in the four-byte adProdPhysAddress
field of the trap packet. The first two bytes are the Unit ID
of the base controller (least significant byte first). The next
two bytes are port and slot number. This field is the sec-
ond object identifier in all traps sent from TSU/TDU
products. For traps from the ISU 512, the Unit ID is the
first object identifier. See the product MIBs for more infor-
mation.
Definitions for Poll Link Up/Down traps are included in
the TDU 120e MIB file: TDU 120e.MIB.

RFC1406.MIB.
Create device entries in the NMS database for all units
that are to be managed through the TDU 120e.

The host unit should be configured as the Proxy agent for
the external units. The IP address or host name used for
the proxy designation is that of the TDU 120e.
Set community names in the device’s entries for external
units to the TDU 120e community name with the device
Unit ID appended.
See TDU 120e SNMP ACCESS on page A-4 for more
information.
