1Overview
This user manual describes the TAC 2010 module, a component of
Verilink’s Access System 2000 (AS2000) platform. The TAC 2010 is
a T1 Channel Service Unit (CSU) that can optionally be used with up
to 24 Verilink Data Service Unit (DSU) modules.
Scope
This manual assumes you are already familiar with the AS2000
product line. Where appropriate, the text refers you to a specific
Access System 2000 manual for greater detail.
Installation
Information For information on installing and replacing shelves, modules, and
power supplies, see the manual AS2000, The Basics.

Management
Options The TAC 2010 CSU module must be managed by one of five Verilink
node controller modules; the NCC 2020, NCC 2130, SCC 2020, SCC
2130 or NCM 2000. You can configure the TAC 2010 through an
ASCII terminal port (Craft interface) on the associated node
controller.
Depending on the controller module used, you can manage the TAC
2010 using either of two Verilink node management programs or an
industry standard SNMP manager. Table 1-1 lists the node
management programs which can be used with the three types of
node controller.

Compatible
Modules The TAC 2010 defaults to CSU-only mode. It can be configured to
use a shelf midplane to pass channelized data timeslots to an
optional DSU module.
Table 1-2 Compatible DSU Modules
Components
The complete TAC 2010 assembly consists of a front-panel module
and a rear panel connector interface module (CIM), together
occupying a single shelf-slot position accessible from the front and
back of the AS2000 shelf. The CIM is installed from the rear of the
shelf into the backplane. The TAC 2010 front module is installed
from the front. The CIM is always installed first and removed last.
The TAC 2010 module is installed last and removed first, using the
dual ejector handles.
TAC 2010 Front
Panel The TAC 2010 front panel provides LED indicators and signal
access jacks. It has dual ejector levers to aid installation and
removal of the module.
NOTE: The bantam type signal access jacks provide access to
internal signals within the module. If the TAC 2010 is being
used with any type of DIU (DSU) module, the signals on the
bantam jacks will NOT reflect line signals and this jack field
should not be used.
Module Type Usage
DIU 2130 DSU DSU with two synchronous serial interface ports for connection of Data
Terminal Equipment (DTE). May be used with TAC 2010 (including the TAC
2010 portion of an NCC 2020).
DIU 2130/DBU DSU DSU with a single synchronous serial interface port and modified firmware
which uses the second port to switch the DTE data from port 1 to an
external Dial Back-Up device—which must be configured to dial on DTR.
DIU 2130
56K/NMS DSU DSU with two synchronous serial interface ports and support for routing of individual timeslots, in the “telco cloud”, to remote sites with 56K DDS
circuits. Uses a shelf midplane to receive/transmit data to a CSU module.
DIU 2140 Sub-Rate
Data
Multiplexer,
5 port DSU
DSU with five RS-232 interface ports, each individually selectable for sync
or async data, which are multiplexed into a single timeslot (DS0) of the

Port Located Usage
Bantam Jacks Front Monitor network signals, DSX-1 equipment signals, connect T1 test
equipment. These ports do not reflect line signals unless the module
is in CSU mode. Use only when in CSU mode (DIU bus = none).
The MON pair is used to monitor receive or transmit data and is non-
intrusive. MON NET allows access to the T1 receive data. MON EQPT allows
access to the CSU transmit data.
The EQ pair disconnects the DSX-1 equipment and replaces it with the test
set. Use of EQ IN or EQ OUT will disrupt any service operating on the entire
T1.
The NET pair disconnects the rest of the CSU from the T1 circuit and allows
the test set to replace the CSU. Use of NET IN or NET OUT will disrupt any
service operating on the T1.
Network Rear Connect the T1 line to this port.
Equipment Rear Connect customer equipment which presents a DSX-1 T1 framed signal—
often a PBX. This port is only used if the module is in CSU mode or drop and
insert mode.
Ext Timing Rear Connect an optional external clock source, using either a TTL (Transistor
Transistor Logic) level (0 to +5V) or balanced (RS-422) signal. The clock must
be at 1.544 Mbit/s.
Alarm Relay Rear Connect an external alarm system which will trigger on either a relay closure
(using NO and COM leads) or an open (using NC and COM leads). The relay in
the TAC 2010 module supports Form C relay specifications.

CSU
Configuration When installing a TAC 2010 module to be used with any type of DIU
21xx module, always configure the CSU module before configuring
anything on the DIU 21xx module. When the DIU 21xx is
configured, it is connected logically to a CSU. At that instant the
DIU gets information from the CSU as to which data bus in the shelf
midplane to use. If the CSU has not been configured yet, the DIU
21xx will not get a correct bus assignment. This is why the CSU
should be configured first.
Type “C” and press ENTER. The Configuration Menu is presented.

The factory default values for the TAC 2010 are shown. The unit is
in CSU mode (DIU bus = NONE
NONENONE
NONE) and the network interface (shown at
top right) is set for ESF framing and AMI line coding format.
The DSX-1 Equipment interface, shown at top left, is set for SF (D4)
framing and AMI line code. For this quick set-up, the equipment
interface is not being used, as it would be in CSU mode or drop and
insert mode. Because this example will use all 24 timeslots for data
on a DIU 2130 module, Mux mode is required.

2. Select “2” to use Data Bus A. This means that the CSU and the
DIU 2130 will use Data Bus A in the shelf to pass data back and
forth. The CSU is now in Mux mode. The EQPT LED changes
from red to green.
3. Type “F” and press ENTER. The prompt for line format appears:

4(B8ZS,B8ZS) >. Select “4” for B8ZS (since the Equipment side
interface is not used, selection 2 would also work).
4. The default value for the density enforcement selection is not
correct for a B8ZS T1. Use the “Z” command and select “1” to
change it to NONE. B8ZS was developed to eliminate the need
for density enforcement.

5. For this example, a Network Service Provider (NSP—the phone
company) is providing a timing signal with a Digital Access
and Cross-connect System (DACS). This is usually the case
where an inter-exchange carrier (long distance company) is
involved. When the carrier provides a timing signal, all other
devices on the T1 must use that signal to derive their transmit
clock. Use the “B” command for the DIU timing options and
select “5” for NET (recovered NETwork clock).
6. There are no more changes required to the default CSU
configuration to configure this example. Use the “X” command
to return to the controller Main Menu.
Configuring the
DIU 2130 For this example, the TAC 2010 is used with a DIU 2130 module in
slot 6 of a Multi-line shelf. The TAC 2010 connects directly to the
T1 circuit and provides CSU functionality. The DIU 2130 presents
two synchronous serial interfaces for connecting the Data Terminal
Equipment (DTE) and provides DSU functions.
To configure the DIU 2130, first select it.
The S) shelf/slot
S) shelf/slotS) shelf/slot
S) shelf/slot
command is used to navigate from one module to
another. Type “S” and press ENTER. The prompt for selecting
another module appears. Type “1,6” and press ENTER.
The prompt line returns as: [1,6] DIU 2130 (UPDATE) >
[1,6] DIU 2130 (UPDATE) >[1,6] DIU 2130 (UPDATE) >
[1,6] DIU 2130 (UPDATE) > this indicates
that the DIU 2130 in slot 6 has been selected.
NOTE: Whenever the word UPDATE appears in the command line
prompt, it indicates that some information has changed since
the screen was last refreshed. To refresh the screen with
current information, simply press ENTER.
Configuration
Menu Type “C” and press ENTER to select the DIU 2130 Configuration
Menu.
There is a brief delay as the node controller module attempts to
communicate with a CSU module in Shelf 0, Slot 0 . This is the
default value for CSU assignment in a new DIU 2130 module.
NOTE: An address of Shelf 0, Slot 0 is not a valid address. Modules
are shipped this way so they may be added to a shelf without
interfering with any existing applications.
An error message appears:
No response from csu[ 0,0 ]
No response from csu[ 0,0 ]No response from csu[ 0,0 ]
No response from csu[ 0,0 ].
The error message, in this case, means that the DIU 2130 is new
and has not assigned to a CSU module. Ignore this error message.

Then the DIU 2130 Configuration Menu is displayed.

NOTE: For the remainder of this chapter you will not be instructed
to press ENTER each time. Generally, the ENTER key is used
after each command or value entry.
The CSU command is used to assign the DIU 2130 module to the
CSU with which it will be used. The TAC 2010 CSU module in slot 5
will be used for the CSU in this example. Type “C”. At the prompt
enter shelf >,
enter shelf >,enter shelf >,
enter shelf >, type “1”. At the prompt enter slot >
enter slot >enter slot >
enter slot >, type “5”. This
selects the TAC 2010 in slot five of shelf one as the CSU for this DIU
2130 module.
The Timing Source defaults to CSU, meaning that the DIU 2130 will
derive its transmit clock from the source selected in the CSU
configuration (recovered network clock in this example). This is
correct for this example.
In the middle of the display, a line across the screen lists all 24
timeslots. The DS0 (timeslot) selection prompt appears at the
beginning of the next line, Dp
DpDp
Dp. The lowercase pis a variable,
instead of typing “p” use a port number (1 or 2). For this example
timeslots 1 through 12 are to be used on data port number 1 and
timeslots 13 through 24 are to be assigned to data port number 2.
Type “D1”, the prompt enter port 1 channels >
enter port 1 channels >enter port 1 channels >
enter port 1 channels > appears.
