Chapter 1 Introduction
T3 MODULE OVERVIEW
The T3 Module and the T3 D/I (Drop and Insert) Module are members of the
ATLAS family of integrated access products providing one or two channelized T3
interfaces. The T3 Module combines with the ATLAS Base Unit and other ATLAS
modules to support requirements calling for delivery of multiple T1 circuits. The
modules terminate all 28 T1s of a channelized T3 into the ATLAS TDM Backplane
for use in dedicated or switched services. The T3 module has a DSX-3 level physical interface and the T3 D/I module has two T3 interfaces. The T3 D/I module
may terminate between 2 and 28 T1s as the T3 into the ATLAS and pass through
the remaining bandwidth out of the secondary T3 port. The secondary T3 port
may not be used to terminate bandwidth on the ATLAS, but passes the T1s back
out the primary T3 interface. Timing for the ATLAS may be sourced from the T3
module. The timing sources available from within the T3 module are any of its
odd numbered T1s (1-27), the internal 44.736 MHz oscillator (STRATUM 4), or the
T3 receive clock. The T3 module supports dedicated T1 links as well as robbed-bit
switched terminations.
Typical applications calling for ATLAS and the T3 Module include the following:
• Digital Access Cross Connect System (3/1/0 DACS). Any DS0 on any T1 circuit delivered on the T3 can be switched to any other DS0 on any other circuit.
• T3 Bandwidth Management. A T3 circuit carrying voice, data, video, and other
traffic can have its payload groomed and directed to the appropriate interface
inside the ATLAS system.
Figure 1-1 on page 1-2 shows the T3 bandwidth management application.

and Run Self-Test.
Factory Restore
Factory Restore, a submenu of the ATLAS 800 front panel main menu item Utilities (UTIL), restores the factory-installed default setting for all T3 Module parameters. When Factory Restore displays, place the cursor on it and press ENTER.
The unit is restored to preset factory defaults and returns to the main ATLAS 800
menu.
Run Self-Test
Run Self-Test, a submenu of the ATLAS 800 main menu item Test, executes both
the T3 Module internal test and the ATLAS 800 internal test. For additional information on Self-Test see the ATLAS 800 User Manual. When Run Self-Test displays,
place the cursor on it and press ENTER to execute the test. The results of the selftest are displayed in the LCD.
Mapping
DS0s are used as defined in the Dedicated Map or in the Dial Plan for switched
applications. (See the ATLAS 800 User Manual for a description.)

Appendix A Dial Plan Interface Configuration
INTERFACE CONFIGURATION
The interface configuration option for the Dial Plan menu sets configuration
parameters for the end point. These parameters vary by the type of port selected.
The following section describes the configuration options available for the T3-1
and T3-2 Modules. The Dial Plan menus are only accessible when using terminal
mode. To access these options, select Dial Plan from the top level menu (see Figure A-1).
The Write security level for all Dial Plan options is 3.
Figure A-1. Dial Plan Menus
T3 MODULE INTERFACE CONFIGURATION
This section describes the network termination and user termination configuration settings for the T3-1 and T3-2 Modules when using the Dial Plan menus.
These menus represent the T3 Module as having 28 T1 ports to configure.

Appendix A. Dial Plan Interface Configuration
T3 Module (Network Termination/RBS)
When you are working in the Network Termination section of the Dial Plan menu,
Slot is defined as a T3-1 or T3-2 Module, and Sig is set to RBS, the following inter-
face configuration options are available:
First DS0
Write security: 2; Read security: 5
Defines to the ATLAS 800 the DS0s used for this end point. These are the DS0s
which the ATLAS 800 uses to send and receive calls to and from the network
(PSTN). The outgoing calls which are allowed or restricted over these DS0s
are set by the Outgoing Call Accept and Reject Numbers discussed earlier.
Number of DS0s
Write security: 3; Read security: 5
Specifies the number of DS0s already defined for this end point. This field is
read-only.
DS0s Available
Read security: 5
Indicates which DS0s of the T1 have been defined in this switched end point
(indicated by "!"), in another switched end point (indicated by "s"), or in a
Dedicated Map (indicated by "n"). The following symbols may display in this
field:
digits
0-9
*
!
s
S
n
N
This DS0 is available. The digit that displays in this field represents
the last digit of the DS0 number.
This port is requesting this DS0 for this connection, but the DS0 is
not yet activated.
This DS0 is used by this end point.
This DS0 is used elsewhere in the switched dial plan.
This DS0 is in the switched dial plan and conflicts with this end
point.
This DS0 is used in one or more dedicated maps.
This DS0 is in one or more dedicated maps and conflicts with this
end point.
Trunk Type (Voice/SW56)
Write security:3; Read security:5
Use this field if the incoming service on this trunk is Switched 56 digital
instead of standard voice.
Signaling Method
Write security: 3; Read security: 5
Defines to the ATLAS 800 the type of signaling to be used across this trunk.
The signaling selected needs to match the signaling being provided by the
network (PSTN). The following choices are available:
• E&M Immediate
•E&M Wink
•Loop Start
• Ground Start
A-2 T3 Module User Manual 61200223L1-1
Appendix A. Dial Plan Interface Configuration
Direct Inward Dialing (DID)
Write security: 3; Read security: 5
Defines to the ATLAS 800 whether DID is being used by the network. If DID
is Enabled, then you must define the following information:
DID Digits Transferred
Write security: 3; Read security: 5
Defines the number of digits sent to the ATLAS 800 from the network if
DID is used.
DID Prefix
Write security: 3; Read security: 5
Defines to the ATLAS 800 the prefix digits which are not received as a
part of the DID number. ATLAS uses the combination of prefix and DID
number to determine the user end point that should receive the incoming
call.
This option displays only if direct inward dialing (DID) is set to Enabled.
If DID is Disabled, then you must define the trunk number.
Trunk Number
Write security: 3; Read security: 5
When the network connection does not provide DID digits, the ATLAS 800
must be given a number to use to determine which user end point should
receive the incoming call. This option displays only when direct inward dialing is set to Disabled.
The trunk number must be specific (i.e., no “wild cards”).
For example, if an incoming DS0 (trunk) is meant to connect to an end point
with the Accept number of 963-8615, the trunk number would be set to 963-
8615.
T3 Module (User Termination/RBS)
When you are working in the user termination section of the Dial Plan menu,
when the Slot is defined as a T3-1 or T3-2 module, and when Sig is set to RBS, the
following configuration options are available:
First DS0/Number of DS0s
Write security: 3; Read security: 5
Defines to the ATLAS 800 the DS0s which will be used for this end point. The
ATLAS 800 uses these DS0s to send and receive calls to and from user equipment (PBX). The incoming calls which will be accepted and the outgoing calls
which will be restricted over these DS0s are set by the Incoming Call Accept
and Outgoing Call Reject Numbers discussed earlier.
61200223L1-1 T3 Module User Manual A-3
Appendix A. Dial Plan Interface Configuration
DS0s Available
Read security: 5
Indicates which DS0s of the T1 have been defined in this switched end point
(indicated by “! “), in another switched end point (indicated by “s”), or in a
dedicated map (indicated by “n”).

selected signaling must match that being used by the user equipment (PBX).
The choices include the following:
• E&M Immediate
•E&M Wink
•Loop Start
• Ground Start
ATLAS converts signaling types between network and user terminations.
Direct Inward Dialing (DID)
Defines to the ATLAS 800 whether DID is used by the user equipment. If DID
is Enabled, then the following information must be defined:
DID Digits Transferred
Defines the number of digits the ATLAS 800 sends on to the user equipment. This field only displays if direct inward dialing is set to Enabled.
