1. GENERAL

This practice provides installation and maintenance
information for the 9004 U-BR1TE II L2, part number
1425.020L2, and the 9004 U-BR1TE II w/PWR L4, part
number 1425.020L4. Figure 1 is an illustration of the
9004 U-BR1TE II.
The 9004 U-BR1TE II (L2 and L4) are line cards designed
to operate with the Siemens 9004 A/B channel banks.
Both lists of the 9004 U-BR1TE II 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 9004 U-BR1TE
II may be used in the Central Office Terminal (COT)
location and in the Remote Terminal (RT) location. Each
list of the 9004 U-BR1TE II plugs into a single physical
slot but requires up to three consecutive time slots when
configured for 2B+D.
performance over the T1 facility is monitored and available
to the network.

Figure 1. Siemens 9004 U-BR1TE II

The 9004 U-BR1TE II w/PWR 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 9004 U-BR1TE II is interchangeable with the
Siemens ISDN Basic Rate Interface Unit (BRIU), part
number 91469-01 and the ADTRAN 9004 U-BR1TE L1.
Features of the 9004 U-BR1TE II (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.
