Features

The U-BR1TE V features support both ISDN and DDS, plus features common to both as listed here:

ISDN Features

•Span powers U-repeaters with 43 mA @ -28 to -120 VDC for ISDN applications.

•Internal test pattern allows for testing of individual B Channels without requiring external test equipment.

•Transportation of ISDN Basic Rate 2B+D information over T1 facilities in the 3-DS0 format specified in TR-NWT-000397.

•B1 and B2 loopback addressability at the front panel for the NT1 and up to six devices in the Network-to-Customer direction.

DDS Features

•Span powers an IDSL OCU-R with 12 mA @ -120 VDC for DDS applications.

•Transmit MUX-Out-of-Sync (MOS) trouble code upstream for IDSL loss of signal, loss of sync, or open loop.

•Perform bidirectional loopback (loop and network) when commanded into DS0 DP loopback from the network direction only.

•Initiate in-band OCU loopback to loop the IDSL OCU-R via front panel push button.

•Loopback release in response to TIPs per TR62310 or front panel push button.

•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.

•Returns Abnormal Station Code (ASC) to the network in B1 during loopback conditions initiated by the IDSL OCU-R.

2B Leased Mode Features

•DDS loopback operation during 2B data mode only.

Common Features

•ISDN 2B1Q interface which meets all Layer 1 requirements as specified in ANSI T1.601-1991.

•18 kft nominal range on mixed gauge wire.

•All Layer 1 maintenance function and performance monitoring as specified in TR-NWT-000397 and TR-TSY-000829.

•Distinctive metallic DC test signature to identify either line unit LT or line unit NT mode of operation as specified in TR-NWT-0000397.

•Provides loopback capability for full 2B+D as well as individual B channels in both loop and carrier directions. Individual B channel loopbacks may be initiated at the U-BR1TE V front panel or from a remote location through the maintenance channel.

•DS0 logic level transmit and receive data access through front panel bantam jacks.

•A built-in Cyclic Redundancy Check (crc) clock error detector allows for local performance monitoring at the front panel without test equipment.

•Addressing and error status with front panel LED indicators. Test function chosen by a front panel ten-position rotary switch.

The U-BR1TE V is compatible in functionality and is interchangeable with the U-BR1TE III w/PWR (1103020L4) except when used in DDS applications. In addition to being compatible and interchangeable with the just mentioned ADTRAN unit, the U-BR1TE V, adds features in leased mode, including DS0 DP latching loopback and sending Multiplexer-Out-of -Sync (MOS) toward the network.

SUBJECT TO ELECTROSTATIC DAMAGE

OR DECREASE IN RELIABILITY.

HANDLING PRECAUTIONS REQUIRED.

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.

Physical Requirements

The U-BR1TE V plugs into a single D4/SLC-96 channel slot. The backplane pin assignments are illustrated in Figure 2. When provisioned for basic rate service (2B+D), the U-BR1TE V occupies three time slots. In a D4 or SLC-96 Mode III channel bank, it occupies the time slot associated with the physical channel slot that it occupies plus the next two time slots to the right. The physical channel slots, whose time slots are used in this manner, must remain unoccupied.
