Chapter 1 Introduction
Nx/DBU V.35 OPTION MODULE OVERVIEW
The Nx/DBU V.35 option module is one of the option
modules available for use with the following TSU units:
• TSU 100
• TSU 120
• TSU 600
• TSU 610
The Nx/DBU V.35 option module installs in the option
slot of the TSU units and provides an additional synchronous V.35 interface port with dial backup capability.
When used in these products, this interface port allows an
additional DTE to have access to the T1 service with dial
backup capability in the event of a T1 failure.
In the remainder of this manual, the module will be
called the Nx/DBU option module.
Functional Description
The Nx/DBU option module operates in the option slot of
the TSU units and is under the control of the TSU. The
Nx/DBU option module is configured from the front
panel or by an external PC program. The internal menus
for their configuration are part of the Nx/DBU option
module and are automatically installed when the Nx/
DBU is installed in a TSU unit.

Chapter 1.Introduction
FEATURES OF THE NX/DBU OPTION MODULE
Nx Features
• Data rates from 56 kbps to 2.048 mbps in 56K or 64K
increments
• Includes an elastic store for adsorption of rate variations
• Executes and responds to V.54 looping codes
• Outputs a 50 percent duty cycle output clock at all
rates
• Provides an inband control channel (8 kbps for network management communication)
• Generates and checks 511 test pattern toward network
• 511 pattern generator is capable of injecting errors
DBU Features
• Can verify integrity of dial-up netwo r k with a test
pattern without disrupting T1 data
• Detect no data transitions on the data received from
the network, with verify over inband channel
• User-definable delay between call retries if backup
connection is not successfully established
• User-definable verification of dial up network (Daily
Weekly, or On Command) without T1 data disruption
• Backup can be initiated by:
- Alarm conditions on network (AIS, RAI, or Red
Alarm)
- Absence of data transitions for a user-defined delay
• Uses 8 kbps channel to check end-to-end connectivity
before activating backup
• Disable backup based on hour of day and weekend
• Uses pattern to validate backup dial network
