Transport Multiplex Layer; Message-Oriented Service (Frame Sequence) - Motorola MOSCAD 68P02958C00-B User Manual

Enable
Disable
Interval between FULL DUPLEX TX retries <10-100> *100mSec
The period of time that should elapse before a retry takes place in Full Duplex. New data
frames cannot be sent to the retried unit.

Transport Multiplex Layer

Number of MASTER logical channels <64-64>
Number of logical channels in the MDLC protocol capable of initiating communication via a
session oriented channel. Do not change this value.
Number of SLAVE logical channels - <0-7>
Number of MDLC logical channels that can be accessed through one or more masters
simultaneously.

Message-Oriented Service (Frame Sequence)

Stop transmitting 'Reset ack' after <5-10000> Sec
The period of time during which a Reset ACK should be transmitted to a unit that is expected
to return a void frame at Transport Multiplex level for each Reset ACK. After the period of
time specified here, the unit stops sending Reset ACKs in order to identify another reset
situation, should it occur.
Max. allowed delay for a duplicate frame <5-200> Sec
A frame that is received again during this period of time is considered a duplicate, and
discarded. If it arrives after this time, it is considered to be a new frame.
'Hole declaration' time out <1-30000> Sec
The period of time during which frames that failed to arrive as part of a chain are allowed to
be retried at Data Link level. This timeout is calculated as a function of the number of retries
and the data speed.
Allowed reception range from 'Expected frame' <4-128>
The gap that will cause the unit to move to synchronization at Transport Multiplex level. For
example if the value is 16 and frame x+16 arrives while x was expected, synchronization will
take place.
Max. range to declare 'Duplicate frame' <4-128>
The allowed interval between retried frames. For example, if the value is 16 and x-16 arrived
while x is expected, the unit moves to perform synchronization as in the previous parameter.
Network will send a control frame in order to check whether the link is still in
"failed" status. The frame is issued if the link has been in "failed" status for the
period of time specified in the previous parameter.
The link is considered to be back in order after the period of time specified in the
previous parameter.
