Outgoing call (CPE) DISCONNECT RECEIVE – This is the value that the
LEI expects to see from the CPE when the customer equipment wishes to
end the call. This value is required.
Outgoing call (Far-end) DISCONNECT SEND – This is the value that the
LEI sends to indicate that the far-end has released the call. This value
is required.
Disconnect Time – This is the number of milliseconds that the LEI sends
the disconnect signal to the CPE before reverting to the idle state. If the
CPE reverts to a connected state during this time, it is ignored. This value is
only used when disconnect supervision is available and is needed for the
signaling type in use. It is used when the far-end initiates the disconnect.
For loop start cases, this value is not used.
Intercall (release guard) Time – This is the number of milliseconds that
the LEI maintains the idle signal to the CPE before initiating a new call. The
CPE should not initiate a new call during this time. If it does so, the off-hook
indication is ignored until the release guard time has expired. This value
defaults to 0 which relies on the M-1 to observe the proper guard time. If a
non-zero value is entered, off-hook from the CPE and Ringer-On commands
from the M1/SL100 is ignored until this timer has expired.
Display Configuration (D C)
The Display Configuration (D C) command displays the various
configuration settings established for the LEI. Entering this command
causes a screen similar to
