The line status registers (S70 .. S78) are indeed documented as
follows in the manual.  In case of misplaced manuals, they are:

S70	Instantaneous Transmit Rate.  Outbound raw bit rate, not
	necessarily the actual throughput.

S71	Transmit Bits Per Channel.  Reports number of bits
	currently in use for all 511 carriers.  Read only.

S72	Istantaneous Receiver Rate.  Inbound raw bit rate, not
	necessarily the actual throughput.

S73	Receive Bits Per Channel.  Reports number of bits
	currently in use ofr all 511 carriers.  Read only.

S74	Received Packets Retrasmitted.  Number of received packets
	requiring retransmission since start of this call.
	Read only.

S75	Packets Accepted.  Number of good packets received since
	current call began.  Read only.

S76	Equivalent Line Noise Profile.  CNR to the nearest 1/10th
	dBm at all 511 frequency points.  Read only.  Now this is
	definitely a cool register!

S77	Frequncy Offset.  Observed frequency offset of the communi-
	cations channel in Hz. to the nearest 1/16 for the current
	connection.  Valid for either PEP or regualr connection.

S78	Slow Mode Line Quality.  Merit figure 0 .. 100.  50 or
	or higher menas that the line will support acceptable
	communication.  Redialing is recommended if you have a
	merit of less than 30.
