You use BCTIMES to dynamically specify the time intervals for protocol timers and additional protocol timers. With this command you can also specify the time intervals for monitoring incoming messages, connection requests or warnings.
The values which can be set with BCTIMES are mostly protocol timers. The setting of these must be carried out homogeneously in the network and requires a sound knowledge of the relevant standards and networks.
When using MSCF in multiprocessor networks, please note that MSCF must be terminated before BCEND is issued.
You should also use MAX-MSCF-DELAY to define an interval that is long enough to ensure a structured shutdown of the MSCF connections before BCEND. This value will depend on the size of the network.

ARP-SUPERVISION=...
Time interval in seconds for ARP monitoring.
The value is rounded up to a multiple of 5 seconds; the timer has a precision of 5 seconds.
ARP-SUPERVISION= *unchanged
The value set remains unchanged.
BCAM session default: 300
ARP-SUPERVISION=<integer 5..32765>
The time interval is set to the specified value.
CONFIGURATION=...
Time interval for the ISO9542 configuration timer for the sending of ESHs in seconds.Values which are greater than 900 or less than 150 are changed to 900 or 150. The value is rounded up to a multiple of 2 seconds; the timer has a precision of 2 seconds.
CONFIGURATION= *unchanged
The value set remains unchanged.
BCAM session default: 300
CONFIGURATION=<integer 150..900>
The time interval is set to the specified value.
CONN=...
Timeout for connection requests in seconds.
Connection requests which are not accepted or rejected within the timeout are automatically rejected (passive connection setup).
Active connection setups are terminated following the timeout.
The value is rounded up to a multiple of 5. The timer has a precision of 5 seconds. Protocol timers (e.g. ISO8073 Retransmit) have precedence! The time-out is extended when multiple routes are present for an active connection setup.
CONN= *unchanged
The value set remains unchanged.
BCAM session default: 30
CONN=<integer 5..32765>
The time interval is set to the specified value.
DATAGRAM=...
Timeout for incoming requests of the connectionless transport service in seconds.Messages which are not received within the timeout are automatically deleted.
The value is rounded up to a multiple of 5 seconds; the timer has a precision of 5 seconds.
DATAGRAM= *unchanged
The value set remains unchanged.
BCAM session default: 90
DATAGRAM=<integer 5..32765>
The time interval is set to the specified value.
INTF-LIFETIME=...
Time interval for ISO8473-LIFETIME (Layer 3 profile=INTF) in seconds.
The value is entered in the ISO8473 protocol elements. Values which are greater than 127 are changed to 127.
INTF-LIFETIME= *unchanged
The value set remains unchanged.
BCAM session default: 30
INTF-LIFETIME=<integer 1..127>
The time interval is set to the specified value.
IP-LIFETIME=...
Time interval for IP-LIFETIME in seconds.
The value is entered in the IP protocol elements. Values which are greater than 255 are changed to 255.
IP-LIFETIME= *unchanged
The value set remains unchanged.
BCAM session default: 32
IP-LIFETIME=<integer 1..255>
The time interval is set to the specified value.
I-REASSEMBLY=...
Time interval for the IP and ISO8473 reassembly timers in seconds.
Elements which are not completely reassembled within the time interval are deleted. Values which are greater than 255 are changed to 255. The timer has a precision of 2 seconds.
I-REASSEMBLY= *unchanged
The value set remains unchanged.
BCAM session default: 30
I-REASSEMBLY=<integer 1..255>
The time interval is set to the specified value.
LETT=...
Timeout for incoming messages of the connection-oriented transport service in seconds. Messages which are not received within the timeout are deleted.
The value 0 (for infinite) can no longer be set subsequently. Instead you should set a large value from the time interval.
LETT= *unchanged
The set value remains unchanged.
BCAM session default: 0 (stands for infinite).
LETT=<integer 0..32767>
The time interval is set to the specified value.
MAX-MSCF-DELAY=...
Time interval in seconds for termination of MSCF on BCEND.
The value is rounded to a multiple of 5 seconds. The timer operates to a precision of 5 seconds. If BS2000 is operated without MSCF then the timer has no effect.
MAX-MSCF-DELAY= *unchanged
The set value remains unchanged.
Default for a BCAM session: 60
MAX-MSCF-DELAY=<integer 5..32765>
The time interval is set to the specified value.
RETRANSMISSION=...
Time interval for the ISO8073 retransmission timer in seconds (2 to180).
A protocol element which must be acknowledged is retransmitted if it was not acknowledged by the partner transport control during the time interval.
The value is rounded up to a multiple of 2 seconds. The timer has a precision of 2 seconds.The retransmission timer is only to be changed where absolutely essential.
The timer has major effects on the loading of the system and the network.
It should be noted that changes to WINDOW values also affect RETRANSMISSION!
For WINDOW=*STD, the RETRANSMISSION value is 10.
RETRANSMISSION=*UNCHANGED
The value set remains unchanged.
BCAM session default: 10
RETRANSMISSION=*STD
The time interval is changed to the default value of 10 seconds.
RETRANSMISSION=<integer 2..36>
The time interval is set to the specified value for the currently existing routes with
L3 profile ISO.
The default value for all routes with L3 profile ISO set up following the BCTIMES command remains unchanged.
WARN=...
Timeout for warnings in seconds, 1 to 32765.
The value is rounded up to a multiple of 5; the timer has a precision of 5 seconds.
Corresponding command functions are only executed if the timeout expires after the warning (see the W operand in the BCAPPL, BCOUT, BCDAC, BCCONN, and BCEND commands).
WARN= *unchanged
The value set remains unchanged.
BCAM session default: 10
WARN=<integer 5 ..10..32765>
The time interval is set to the specified value.
WINDOW=...
Time interval for the ISO8073 window timer in seconds.
If nothing was sent on a connection during the time interval, an acknowledgment element (AK-TPDU) is sent.
The value is rounded up to a multiple of 2 seconds; the timer has a precision of 2 seconds. Values which are greater than 180 are changed to 180.
If the value for WINDOW is changed, the maximum for the RETRANSMISSION value (one fifth of the WINDOW value) is also changed.
WINDOW=*UNCHANGED
The time interval of the window timer remains unchanged.
BCAM session default: 60
WINDOW=*STD
The time interval of the window timer is set to the default value of 60 seconds.
WINDOW=<integer 2..180>
The time interval of the window timer is set to the specified value.
Command logging
For reasons of compatibility, the processing acknowledgment is supplied in news BCA0763 if it is positive and in news BCA0762 if it is negative, followed by the message NBR0740. For positive acknowledgments, the message BCA0628 appears.
