DATA Used to control the inverting of the DTE data. This
inversion can be useful when operating with an
HDLC protocol. Often used as a means to ensure
1s density.
Choices: Normal or Invert
If Invert is selected, zero (0) inhibit should also
be selected to prevent an open DTE input from
placing zeros on the network.
CTS Used to control characteristics of CTS.
Choices: Normal, (see Table 3-A) or Force On
DCD Data Carrier Detect. Indicates to the DTE when a
valid signal is being received at the Network
Interface.
Choices: Normal (see Table 3-A) or Force On
DSR Data Set Ready. This signal indicates to the DTE
when the DCE is turned on and ready for
operations.
Choices: Normal (see Table 3-A) or Force On
0 INHIB The Nx interface will detect an uninterrupted
string of zeros (0s) being transmitted toward the
network. If 0s are transmitted for >1 second, the
TSU 120 will force 1s.
Choices: On or Off
INBAND The Nx56/64 port is capable of providing an
inband communications channel (for T-Watch and
SNMP) between units. This is accomplished by
using 8 kbps of the first DS0 assigned to that
particular Nx56/64 port. If in 56 K mode, no data
bandwidth will be used. Inband must also be
enabled at the destination port.
Choices: On or Off, On Demand
TX CLK
SOURCE
This controls the source of the clock used by the
TSU 120e to accept transmit data from the DTE.
The default is Internal. If the application requires
that the DTE device provides the clock with the
transmit data, the External setting is used.
Choices: Internal, External
