ASPAC retransmission

Hi,

RFC says:

"When the ASP sends an ASP Active message, it starts the timer T(ack).
If the ASP does not receive a response to an ASP Active message
within T(ack), the ASP MAY restart T(ack) and resend ASP Active
messages until it receives an ASP Active Ack message. T(ack) is
provisionable, with a default of 2 seconds. Alternatively,
retransmission of ASP Active messages MAY be put under control of
Layer Management. In this method, expiry of T(ack) results in an MASP_
ACTIVE confirm primitive carrying a negative indication."


how should I interpret "MAY"? Should ASP resends ASPAC or not? Any idea?


Thanks,
Moloud
