SUBJECT TO ELECTROSTATIC DAMAGE

OR DECREASE IN RELIABILITY.

HANDLING PRECAUTIONS REQUIRED.

Earlier versions of the SLC-5 BCU will not recognize

an ISDN channel unit ID, and will not assign the

required time slots of the next physical position for

2B+D operation. For previous versions of the SLC-5

U-BR1TE, a NULL channel unit, which communicated

to the non-ISDN capable BCU, is required to reserve

the associated time slots for 2B+D service.

By automatically determining the version and

requesting the necessary time slots for the non-ISDN

capable BCUs, the U-BR1TE III eliminates the confusion

regarding 2B+D deployment, and the requirement of

deploying the NULL cards. The U-BR1TE III will

operate properly when a NULL card is installed in the

adjacent physical, as in a replacement situation.

Features

U-BR1TE III features support both ISDN and DDS,

plus features common to both as listed here:

ISDN Features:

• Provides for the transport of ISDN Basic Rate

2B+D information over T1 facilities in the 3-DS0

format specified in TR-NWT-000397.

• NULL card not required with non-ISDN BCUs.

• B1 or B2 loopback addressability at the front

panel for the NT1 and up to six devices in the

Network-to-Customer direction.

• Compatible with MLT 3.0/ISDN per

TR-NWT-000397, Issue 3, December 1993.

DDS Features:

• Perform bidirectional loopback (loop and

network) when commanded into DS0 DP

loopback from the network direction only.

• Loopback release in response to TIPs per TR62310.

• Remap all subsequent DS0 DP loopback codes

into respective eoc loopbacks to loop back

respective downstream U-Repeaters, TRISDN

elements, and U-BR1TEs when optioned for

1B+D, or 2B+D.

• Pass OCU loopback code through to loop the

IDSL OCU-R.

• Pass CSU loopback code through to loop the

CSU/DSU and simultaneously send a remap to

the NT1 eoc address.

• Transmit Mux-Out-of-Sync (MOS) trouble code

upstream for IDSL loss of signal, loss of sync, or

open loop.

• Returns Abnormal Station Code (ASC) to the

network in B1 during loopback conditions

initiated by the IDSL OCU-R.

Common Features:

• ISDN 2B+D interface which meets all Layer 1

requirements as specified in ANSI T1.601-1992.

• 18 kft nominal range on mixed gauge wire (42

dB @ 40 kHz loop loss, 1300 Ω DC resistance

design).

• All Layer 1 maintenance functions.

• Performance monitoring of the Layer 1 facility as

specified in TR-NWT-000397.

• A distinctive metallic DC test signature to

identify either Line Unit Loop Termination

(LULT) or Line Unit Network Termination

(LUNT) mode of operation as specified in

TR-NWT-000397.

• DS0 logic level transmit and receive data access

through a front panel RJ-45 jack.

• Loop, carrier, and synchronization status

available at the front panel.

• Compatible with AT&T SLC-2000, SLC Mode 1.

• Compliant with TR-TSY-829, TR-TSY-1089,

FCC Part 15, Class A, and UL 1459.

ADTRAN has obtained the necessary licenses that

grant the right to develop a SLC-5 U-BR1TE III. The

ADTRAN U-BR1TE III replaces the AT&T AU92

(COT) and AU93 (RT) BRITE channel units. The

U-BR1TE III (TR397 compliant) will not function

with the AT&T BRITE channel units across the T1

carrier facilities. The U-BR1TE III must be terminated

across the T1 carrier facilities with another channel

unit that meets TR 397. The U-BR1TE III will

function with any ISDN 2B1Q U-interface that is ANSI

T1.601 compliant.

2. INSTALLATION

After unpacking the unit, inspect it for damage. If

damage is noted, file a claim with the carrier, then

contact ADTRAN. See Warranty and Customer

Service.

To install the U-BR1TE III, hold the unit by the front

panel and insert it into the assigned slot until the edge

connector is firmly seated in the backplane. The ACT

LED on the U-BR1TE III should illuminate GREEN.

The CR and LP LEDs will flash GREEN then

illuminate AMBER. At this point, push the unit latch

upward until it locks into place.
