must be filled with zeros (0). |
FISU Flags - FISU inter-frame flag count (SS7 only)
Sets the number of flag octets to be inserted between transmitted
FISU frames. The flags reduce the frequency of FISU transmission.
Recommended value - 6.
SS7 - Enable SS7 processing
Enables the automatic handling of transmitted and received
FISU and LSSU frames. Refer to Appendix B “Using the SS7 Mode Feature” for details
of the SS7 mode of operation.
AZT - Analyzer terminal for transmitted data
Enables this terminal for monitoring frames transmitted on
the subchannel.
All transmitted frames are copied, and the copy delivered
to the receiving application for this terminal. This terminal cannot
be used to transmit frames.
AZR - Analyzer terminal for received data
Enables this terminal for monitoring frames received on the
subchannel. All received frames are copied, and the copy delivered
to the receiving application for this terminal. This terminal cannot
be used to transmit frames.

Bulk-Rx | Discard-rate |
Discard-rate - Received FISU or LSSU frames to discard (SS7 only)
This determines how many FISU or LSSU frames are received
and discarded before one is passed up to the receiving application.
The actual number of frames discarded is obtained by multiplying
this parameter by sixteen (16).
Recommended value - 200.
Bulk-Rx - Received frame group processing (SS7 only)
This parameter sets the number of received frames to be queued
up before processing. Because of the high volume of short received
frames used with the SS7 protocol, it can be beneficial to CPU performance
not to process each of the received frames as it arrives. Only the
internal processing of HDLC.FRAME is affected by this parameter.
Recommended value - 4.
Predefined Configuration Values |
|
The following parameter can be used in place of the poll and
select parameters to configure an SS7 subchannel with a set of default parameters:
SS7_OPT - Set up an SS7 frame terminal
An example terminal definition using the SS7_OPT parameter
would be:
Term 120 1:6 HDLC.FRAME SS7_OPT 1000 0 0 0 0 "SS7 device port 6"
