1. GENERAL
This practice provides installation and maintenance
information for the DE-4 U-BR1TE II L2, part number
1410020L2, and the DE-4 U-BR1TE II w/PWR L4, part
number 1410020L4. Figure 1 is an illustration of the
DE-4 U-BR1TE II.
The DE-4 U-BR1TE II L2 and L4 are line cards designed
to operate with the Northern Telecom DE-3/4/4E and
DE-4E SMART channel banks. Both lists of the DE-4 U-
BR1TE provide an ISDN U-interface allowing
transportation of Basic Rate ISDN (2B+D) over T1
carriers. This allows ISDN service to be extended
beyond the normal servicing range (18 kft) of an ISDN
ready switch. Either list of the DE-4 U-BR1TE 2nd
Generation may be used in the Central Office Terminal
(COT) location and in the Remote Terminal (RT) location.
Each list of the DE-4 U-BR1TE plugs into a single
physical slot but requires up to three consecutive time
slots when configured for 2B+D. Block error rate (BER)
performance over the T1 facility is monitored and available
to the network.
The DE-4 U-BR1TE II w/PWR L4 provides an ISDN 2B1Q
U-interface that will supply 43 mA to span power an
ADTRAN ISDN U-Repeater II or U-Repeater III.

Each list of the DE-4 U-BR1TE are interchangeable with
the Northern Telecom ISDN Channel Unit (NT4S10AA)
however, provisioning using the DE-4E Smart Transmit/
Receive Unit (STRU) interface is not supported. Features
of the DE-4 U-BR1TE L2 and L4 include:
• ISDN 2B1Q interface meets all Layer 1 requirements
as specified in ANSI T1.601-1992.
• Transports ISDN Basic Rate 2B+D information over
T1 facilities in the 3-DS0 format per TR-NWT-000397.
• 18 kft nominal range on mixed gauge wire (42 dB @
40 kHz loop loss, 1300 Ω DC resistance).
• Respond to all Layer 1 maintenance functions.
• Performance monitoring of the Layer 1 facility as
specified in TR-NWT-000397.
• Distinctive metallic DC test signature to identify either
line unit LT or line unit NT mode of operation.
• B1 and B2 addressability at the faceplate for a local
loopback, the NT1, and up to six devices in the
network-to-customer direction.
