the received data stream.

In unframed receive modes, if the modem detects RTC as described in

Recommendation T.30 prior to initial loss of the high speed carrier, or if the

modem detects V.21 carrier after initial loss of high speed carrier, then the modem

immediately accepts the loss-of-carrier as qualified, without waiting for the FCL

timer to expire.

In HDLC receive modes, if the modem detects HDLC abort prior to initial loss of

the high speed carrier, or if the modem detects V.21 carrier after initial loss of high

speed carrier, then the modem l immediately accepts the loss-of-carrier as

qualified, without waiting for the FCL timer to expire.
