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, and
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
