Table 18 Port Profile (continued)

LABEL	DESCRIPTION
Latency Mode	This field sets the ADSL latency mode for the ports that belong to this
	profile. Select Fast mode to use no interleaving and have faster
	transmission (a “fast channel”). This would be suitable if you have a good
	line where little error correction is necessary.
	Select Interleave mode to use interleave delay when transmission error correction
	(Reed- Solomon) is necessary due to a less than ideal telephone
	line. See Section 8.4 on page 84 for more on interleave delay.
Up Stream	The following parameters relate to upstream transmissions.
Max Rate	Type a maximum upstream transfer rate (32 to 3000 Kbps) for this profile.
(kbps.)	Configure the maximum upstream transfer rate to be less than the maximum
	downstream transfer rate.
Min Rate	Type the minimum upstream transfer rate (32 to 3000 Kbps) for this port.
(kbps.)	Configure the minimum upstream transfer rate to be less than the maximum
	upstream transfer rate.
Interleave	Configure this field when you set the Latency Mode field to Interleave. Type
Delay (ms)	the number of milliseconds (1-255) of interleave delay to use for upstream
	transfers. It is recommended that you configure the same latency delay for both
	upstream and downstream.
Max SNR (db)	Type the maximum upstream signal to noise margin (0-31 dB).
Min SNR (db)	Type the minimum upstream signal to noise margin (0-31 dB). Configure the
	minimum upstream signal to noise margin to be less than or equal to the
	maximum upstream signal to noise margin.
Target SNR	Type the target upstream signal to noise margin (0-31 dB). Configure the target
(db.)	upstream signal to noise margin to be greater than or equal to the minimum
	upstream signal to noise margin and less than or equal to the maximum
	upstream signal to noise margin.
Down Stream	The following parameters relate to downstream transmissions.
Max Rate	Type a maximum downstream transfer rate (32 to 25000 Kbps) bps for this port.
(kbps.)	Configure the maximum downstream transfer rate to be greater than the maximum
	upstream transfer rate.
Min Rate	Type the minimum downstream transfer rate (32 to 25000 Kbps) for this port.
(Kbps.)	Configure the minimum downstream transfer rate to be less than the maximum
	downstream transfer rate.
Interleave	Configure this field when you set the Latency Mode field to interleave. Type the
Delay (ms)	number of milliseconds (1-255) of interleave delay to use for upstream transfers. It
	is recommended that you configure the same latency delay for both upstream and
	downstream.
Max SNR (db)	Type the maximum downstream signal to noise margin (0-31 dB).
Min SNR (db)	Type the minimum downstream signal to noise margin (0-31 dB). Configure
	the minimum downstream signal to noise margin to be less than or equal to
	the maximum downstream signal to noise margin.
Target SNR	Type the target downstream signal to noise margin (0-31 dB). Configure the target
(db)	downstream signal to noise margin to be greater than or equal to the minimum
	downstream signal to noise margin and less than or equal to the maximum
	downstream signal to noise margin.
	Click Add to save your changes to the AAM’s volatile memory. The AAM loses
Add	these changes if it is turned off or loses power, so use the Config Save link on
	the navigation panel to save your changes to the non-volatile memory when
	you are done configuring.
Cancel	Click Cancel to start configuring the screen again.
