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.

Protocol Option Word

The option word is not used with the HDLC.FRAME protocol.

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"
