HARDWARE RING LINE (Factory Option)
When the ESTeem establishes a CONNECT or link with another ESTeem (T/E Light on solid), pin 22 at the ESTeem RS-232C will
change from a -15 vdc voltage state to a +15 vdc voltage state. The RING software command allows the user to change the
output from a latched state to a pulsed state. To change the state of this line program the following from the COMMAND
mode. Factory default = LATCH.
RING = Latch. Pin 22 is high when the ESTeem T/E light is on solid.
RING = Pulse. Pin 22 is pulsed (positive 250 ms.) when the ESTeem T/E light is on solid.
PACKET MONITOR
The PACKM [ON/OFF] command places the ESTeem in a special packet monitor mode. When this feature is enabled the
ESTeem is placed in a receive only mode and will not function as a normal ESTeem. The ESTeem will monitor and report the
status of all message traffic within the network in the following format, the actual packet message will not be outputted.
SA-xxx, DA-xxx, Type Code, R1-Repeater Status, R2-Repeater Status, R3-Repeater Status, Data Bytes Sent
xxx = ESTeem Address
DA = Destination ESTeem
SA = Source ESTeem
R1 = Address of first ESTeem repeater.
R2 = Address of second ESTeem repeater.
R3 = Address of third ESTeem repeater.

I = Information
DISC = Disconnected
RR = Receive Ready
UA = Unnumbered Acknowledge
RNR = Receive Not Ready
FRMR = Frame Reject
REJ = Reject
DM = Disconnected Mode
UI = Unnumbered Information
SABM = Set Async. Balance Mode
