Model No. Running Head PM-IOR Card User Screens and Settings PM-IOR Card
LB DET
Depending on the selection you made for the Loopback Generation mode above, the PM-IOR
Card port will respond to any of the loopback codes generated by a remote system. The
Loopback Detection (LB DET) setting lets you enable or disable this capability on each card
port. However, this setting does not affect local loopback commands from a local control
terminal.
Choose off to have the system ignore remote loopback commands. Choose on to make the
system monitor the card ports for loopback commands sent from the remote equipment. Note
that the system will detect only the loopbacks in the format selected as the LB GEN mode.
When the system detects a loopback code, it loops the data back until the remote equipment
releases the loopback. The w/to (with time-out) setting is the same as on, except that after 10
minutes the system automatically releases the loopbacks initiated by the remote equipment.
ISDN CONN
The ISDN connection (ISDN CONN) feature is not available with this host release.
