2. INSTALLATION

Unpacking and Inspection
After unpacking the unit, inspect it for damage. If
damage is discovered, file a claim the carrier, then
contact ADTRAN. See Warranty and Customer
Service.

Table 2. Configuration Options for a Remote (Slave) Unit

Configuration Description
HTU-R Mode Selects between Master and Slave mode for the T1 Nx64 HTU-R
Clock Selects the HDSL timing source
DTE INT. TYPE Selects the DTE interface connector being used
RATE 56/64 Selects the channel data rate of either 56 kbps or 64 kbps
CHANNELS Selects between contiguous or alternating DS0s
DTE TX CLK Selects the timing source for the transmit data clock
START CHAN Selects the starting channel (01 thru 24) for Nx56/64 kbps operation
# OF CHAN. Selects the number N (01 thru 24) for Nx56/64 kbps operation
DATA Controls the state of the TD and RD leads
CTS Controls the state of the CTS lead from the HTU-R
DCD Controls the state of the DCD lead from the HTU-R
DSR Controls the state of the DSR lead from the HTU-R
61245023L1-5B
Master (HTU-C) ........... The T1 Nx64 HTU-R is configured as the Local (Master) unit
Slave (HTU-R) ............. The T1 Nx64 HTU-R is configured as the Remote (Slave) unit
Network ........................ The T1 Nx64 HTU-R will derive HDSL timing from the network
Internal ......................... The T1 Nx64 HTU-R uses its internal oscillator to generate HDSL
timing
DTE .............................. The T1 Nx64 HTU-R derives HDSL timing from the DTE
V.35 ............................... Select this option if the DTE is connected to the M/34 connector
V.11 ............................... Select this option is the DTE is connected to the DB11 connector
56 .................................. Selects 56 kbps
64 .................................. Selects 64 kbps
CONT ........................... Contiguous DS0s
ALT ............................... Alternating DS0s
INT_INV ...................... Inverted form of the internal DTE-TX-CLK setting
AUTO ........................... Measures the delay between the DTE data and its clock and
automatically selects between INTERNAL and INT_INV
INTERNAL .................. Allows the Nx64 HTU-R to provide transmit data clock
EXTERNAL ................. Derives DTE transmit clock from the DTE device
NORMAL ..................... Forces normal data format
INVERT ....................... Forces inverted data format
NORMAL ..................... Causes CTS to follow RTS
FORCE ON .................. Causes CTS to be forced on and RTS ignored
NORMAL ..................... DCD is active when loops are in sync and/or when a T1 carrier is present
FORCE ON .................. Causes DCD to be forced on always
NORMAL ..................... Causes DSR to follow DTR
FORCE ON .................. Causes DSR to be forced on and DTR ignored

Configuring the T1 Nx64 HTU-R
The T1 Nx64 HTU-R contains options used to
properly configure the unit. These configuration
options are accessible through the front panel LCD
and push buttons. The T1 Nx64 HTU-R
configuration options are shown in Table 2.
