SIEMENS 9004 A/B CHANNEL BANKS
INSTALLATION/MAINTENANCE
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:
•
I S D N 2 B 1 Q i n t e r f a c e m e e t s a l l L a y e r 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.

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
c o n f i g u r e d f o r 2 B + D . B l o c k E r r o r R a t e ( B E R )
performance over the T1 facility is monitored and available
to the network.
