3.2.3 Control States{XE "Control States"}
The variable {XE "CONTROLSTATE "}CONTROLSTATE represents the current control
state, and will be one of the following values:

{ XE Off-Line/EQUIPMENT OFF-LINE }Off-Line/EQUIPMENT OFF-LINE
The Operator has put the SIPLACE Off-Line. In this state, the Host may not put the
Equipment On-Line, only the operator can attempt this from this state. Any Host-initiated
primary message (except S1F13 and S1F17) will be replied to with an SnF0 ABORT
message by the Equipment. The Equipment will not send any primary messages except
for S1F13 when necessary to establish communications, and the S9F1 and S9F9
messages for SECS errors.

{ XE Off-Line/HOST OFF-LINE }Off-Line/HOST OFF-LINE
While in this state, the SIPLACE will accept either the S1F17 (Go Online), or the S1F13
(Connect Request) message. When in this state, the operator has allowed the Host to
put the Equipment On-Line, but the Host has not yet done so, or the Host has just put the
Equipment Off-Line by sending {XE "S1F15"}S1F15. The Host may request for the
Equipment to come On-Line by sending the S1F17 Go Online message. The Operator
can not put the Equipment On-Line from this state.
The S1F13/S1F14 messages are used to maintain the Communications Finite State
Machine. All messages (except S1F13 and S1F17) received will be replied to with the
SnF0 ABORT message. The Equipment will not send any primary messages except for
S1F13 when necessary to establish communications, and the S9F1 and S9F9 messages
for SECS errors.
{ XE Off-Line/ATTEMPT ON-LINE }Off-Line/ATTEMPT ON-LINE
The Operator has requested that the Equipment go On-Line, causing the transition to this
state. SIPLACE sends a single S1F1, indicating its desire to go On-Line. When either a
transmission failure (here, T3 or RTY errors) occurs, or a successful reply to the S1F1
has been received, a transmission is made out of this state.
{XE "LOCAL"}On-Line/LOCAL
The local operator has control of the SIPLACE.
The only possibility of controling processing is sending RemoteStop {XE "S2F41 "}S2F41
to equipment. Other Remote Commands will be rejected with 0x40 by equipment.In
LOCAL mode, the Equipment continues to send Event and Alarm reports to the Host.
The Host can monitor operations, but cannot control processing, despite RemoteStop.
However, the Host can still exert "controls" other than {XE "S2F41 "}S2F41 which do not
directly affect processing. For example, the Host can enable/disable Alarms and set the
Clock.
{XE "REMOTE "}On-Line/REMOTE
The remote Host Computer has control of the SIPLACE using {XE "S2F41 "}S2F41
(Remote Command).
Power Up{XE "Power Up"}
At Power Up, the Equipment Constant {XE "INITCONTROLSTATE
"}INITCONTROLSTATE (VID 1002005) controls whether ControlState is initialized to
{XE "ONLINE "}ONLINE or {XE "OFFLINE"}OFFLINE. Within the Off-Line super-state,
the Equipment Constant {XE "OFFLINSUBSTATE "}OFFLINESUBSTATE (VID
1002010) controls whether the Control State defaults to:
1 = Equipment Off-Line
2 = Host Off-Line
3 = Attempt On-Line
If INITCONTROLSTATE (VID 1002005) initializes to On-Line, the variable {XE
"ONLINESUBSTATE "}ONLINESUBSTATE (VID 1002009) determines whether
the default state is:
4 = Local
5 = Remote

The following table lists the variables (SV's, EC's, or DVVALS) which are relevant to the
Control State. For a more complete description of these variables, see "Appendix A --
