CIRCUIT BOARD ROTARY SWITCH - SW2
Selects the DSX-1 Line Build Out
■ 0..........0 - sets LBO to 0-133 feet
■ 1..........133 - sets LBO to 133-266 feet
■ 2..........266 - sets LBO to 266-399 feet
■ 3..........399 - sets LBO to 399-533 feet
■ 4..........533 - sets LBO to 533-655 feet
Note: Positions 5,6 & 7 are not used.
CIRCUIT BOARD JUMPER - P1
Selects the span powering voltage
LV (–140 Vdc)
■ Used to span power circuit with 0 or 1 HRE
HV (–190 Vdc)
■ Used to span power circuit with multiple HREs
CIRCUIT BOARD JUMPER - P3
Selects the framing of the HDSL circuit
UNF
■ HTU-C operates in unframed mode
AUTO
■ HTU-C auto detects framing
DSX EQ BANTAM JACKS
Provides an intrusive test access point to the data stream
TX
■ Accesses the data stream being received from the local loop
RX
■ Accesses the data stream being transmitted to the local loop
RS-232 DB-9 CONNECTOR
■ Used to access performance monitoring data, perform loopbacks and provision units
via VT100 emulation software such as Hyper Terminal – Private Edition and
ProComm Plus.
■ Provision terminal port as follows:
Data Rate — 19.2 kbps
Asynchronous Data Format — eight data bits, no parity (none), one stop bit
■ When using a PC with terminal software, be sure to disable any power saving
programs.
