Parameter Deﬁnitions 15

Deﬁning the Number of Back-to-Back Packets To Transmit

The pace_size parameter (see Table 3-6) deﬁnes the maximum number of

back-to-back packets you can transmit at one time. If the value is zero, there

is no limit to the number of back-to-back packets that can be transmitted.

Reporting Transceiver Capabilities

Table 3-7 describes the read-only transceiver capabilities (either the internal

transceiver or the external transceiver), whichever is selected.

Parameter Values Description

pace_size 1 to 255

= Number of back-to-back packets transmitted at one time
