E1/T1 HDLC.FRAME Configuration Values
Select Word
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 p rocessing (SS7 onl y)
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 S S7 subchannel with a set o f 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"
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
