INTERFERENCE STATEMENT

This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference when the equip­ment is operatedin a commercial environment.This equipment generates,uses,
and can radiate radio frequency energy and, if not installed and used in accor­dance with the instruction manual, may cause harmful interference to radio fre­quencies. Operation of this equipment in a residential area is likely to cause
harmful interference in which case the user will be required to correct the inter­ference at his own expense.

Shielded cables must be used with this unit to ensure compliance with Class A
FCC limits.

Change or modifications to this unit not expressly approved by
the party responsible for compliance could void the user’s author­ity to operate the equipment.

CANADIAN EMISSIONS REQUIREMENTS

This digital apparatus does not exceed the Class A limits for radio noise emis­sions from digital apparatus as set out in the interference-causing equipment
standard entitled “Digital Apparatus," ICES-003 of the Department of Commu­nications.

Cet appareil nuerique respecte les limites de bruits radioelectriques applicables
aux appareils numeriques de Class A prescrites dans la norme sur le materiel

CANADIAN EQUIPMENT LIMITATIONS

Notice: The Canadian Industry and Science Canada label identifies certified
equipment. This certification means that the equipment meets certain telecom­munications network protective, operational, and safety requirements. The
Department does n ot guarantee the equipment will operate to the u ser’s satisfac­tion.

Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The equip­ment must also be installed using an acceptable methods of connection. In some
cases, the company’s inside wiring associated with a single line individual service
may be extended by means of a certified connector assembly (telephone extension
cord). The customer should be aware that compliance with the above limitations
may not prevent degradation of service in some situations.

Repairs to certified equipment should be made by an authorized Canadian main­tenance facility designated by the supplier. Any repairs or alterations made by
the user to this equipment, or equipment malfunctions, may give the telecommu­nications company cause to request th e user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connec­tions of the power utility, telephone lines and internal metallic water pipe system,
if present, are con nected together. This precaution may be particularly important
in rural areas.

Users should not attempt to make such connections themselves,
but should contract the appropriate electric inspection authority,
or an electrician, as appropriate.

Introduction

DUAL U-BR1TE PLUG-IN AND PLUG-ON OPTION CARDS

The Dual U-BR1TE Plug-in and Plug-on Option Cards are
compatible with the TSU/TDU/HSU family of T1 multi­plexers. The Plug-in Dual U-BR1TEis designedto occupy
a single slot in a TSU family product and will accept plug­on modules designed for use in this product family. The
Dual U-BR1TE Plug-on Module may be plugged on any
TSU/TDU plug-in module. The Dual U-BR1TE Option
Cards are subject to the host T1 multiplexer's operation
and control.

The Dual U -BR1TEs provide two ISDN U-interfaces and
allow the transport of Basic Rate ISDN (BRI) information
over T1 carriers and unloaded twisted pair wiring.

Functional Description

TheDualU-BR1TEsareconfiguredinthesamemanneras
the host multiplexer. The internal menu for the configu­ration of each U-BR1TE is a part of the Dual U-BR1TE
Module and is automatically available when the Dual U­BR1TE is installed into the TSU.

The Dual U-BR1TEs provide two U-interfaces. Each U-in­terface allows the transmission and reception of Basic
Rate2B+D information overthree consecutive DS0s of the
TSU family's T1 facility and is capable of operating in ei­ther the LUNT or LULT mode.

Figure 1-1. Dual U-BR1TE Plug-in Option Card

The Dual U-BR1TE Plug-in Option Card rear panel in­cludes a plastic plug over a cutout for additional connec­tors. This allows a plug-on board to be added to the Dual
U-BR1TE Card. The PORT X.Yindication is linked to the
port numbering philosophy of the TSU 100 product fam­ily. The Xrepresents the slot number, and the .Y indicates
the port number. F or the TSU 100 application, there is
only one option slot. Therefore the ports are designated

1.1and 1.2. If added,the plug-on boardport designations

POWER UPTESTING AND INITIALIZATION

The Dual U -BR1TE Option Card executes a partial self
test during the power up sequence, as described in the
TSU100/120/600manual. A full self testcan be activated
from the Test menu. No initialization input is required.
Any previously config ured setting for the Dual U-BR1TE
is restored automatically upon power up.

Successful Self Test

The green OK LED, located on the front panel, turns on
when a successful self test is completed and the configu­ration is successfully restored. See the chapter Operation
in the main user manual.

Failed Self Test

If the Dual U-BR1TE card fails one or more of the self
tests,a messageis displayedin theLCD duringpower up.
See the TSU 100/120/600 user manual. Specific failures
of the Dual U-BR1TE Card are identified in the appendix

RESULTS

A U-BR1TE port may be commanded to transmit the in­ternally generated 2047 pattern on the B1 channel in ei­ther the T1 (T1_TX) or the U-interface (LP_TX) direction.
The pattern may be looped back to the U-BR1TE port and
verified with the results viewed by choosing 7)PATT RE-
SULTS, or the 2047 pattern may be verified using test
equipment at accessiblepoints in the network. Errors may
be injected into the transmitted pattern by choosing 6)IN-

JECT ERROR.

B2 2047 PATT operates exactly like B1 2047 PATT,with

the pattern transmitted in the B2 channel instead of the B1
channel.

Selecting this menu item while the U-BR1TE is transmit­ting the 2047 pattern (B1 REMOTE LPBK, B2 REMOTE
LPBK, B1 2047 PATT, B2 2047 PATT) inserts an error in
the transmitted pattern.

Selecting this menu item while the U-BR1TE is transmit­ting the 2047 pattern causes the U-BR1TE to display the
maximum number of errored seconds of the test pattern
on the bottom line of the LCD (ES=xs). The display con­tinues until this menu item is selected a second time.
Pressing

shift-clear

while in this menu resets the errored

seconds to zero.
