ISDN 2B1Q INTERFACE FOR

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:

• 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.

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. Block Error Rate (BER)

performance over the T1 facility is monitored and available

to the network.
