idle See on-hook .
idle code The code transmitted when no
user data is present on the net.
The idle code can be configured
for all-ones or flags [01111110].
Also called idle pattern.
idle pattern See idle code.
IEEE Institute of Electrical and
Electronics Engineers.
inband Within the same frequency band.
inband management Enables node management
software such as Node Manager to
access a remotenode connected to
the port. Node Manager requires
only one T1/E1 timeslot per
remote node to access all modules
at the remote site. On E1 nodes,
inband management always uses
channel 31.
inverse multiplexer A device separating a high
bandwidth signal into multiple
lower speed lines. Use for video
conferencing applications.
inverted send timing Inverted Send Timing (INV ST)
shifts the time at which the data
from the DTE is clocked into the
port’s transmit buffer. Inverted
Send Timing is useful when the
cable length between the DCE and
the DTE is so long that clocking
signals experience propagation
delays. INV ST should only be
used when incorrect data is being
received at the far DTE and ST is
currently selected. If the DTE
device at point B reports errors,
and the CSU at point B does NOT
report errors, change the DIU
timing option from ST to INV ST (or
vice versa) at point A.
