Circuit Card Description and Installation
When the far-end terminates a call, Release 1 of LEI’s AB vintage sends a
disconnect message to the terminal equipment and waits for the terminal
equipment to go idle before going idle itself. A NO response to the S S
command configures Release 2 (and later) boards to operate in this way. See
Figure 47.
Release 2 of AB vintage LEIs gives the administrator the option of using the
signaling described above, or configuring the LEI to take its channel idle
immediately after sending the call-disconnect message. A YES response to
the S S command, the default configuration for Release 2 (and later) boards,
configures the LEI to operate in this way. See Figure 48.
Set Mode
At the SET MODE (S M) command, the MMI prompts the user with the
current signaling mode, either Default (Australian P2) or Table (of bit
values.) Entering a <CR> accepts the current value, or the user can type in 1
to revert to the Default, or 2 to edit the table entries. See Figure 49 on
page 296 . If the user selects default, then the A/B Bit values is reset to the
Default values.
Responding to the MMI’s Set Mode prompt with “1” also results in the line,
“Signaling Bits set to Default,” as in Figure 49.
