3. DSL Card Configuration
3-12
April 2001 8000-A2-GB26-50
DSL Ports (DSL Parameters) 8312/8314 ReachDSL/MVL Cards A-B-A
Provides the ability to configure the operational and alarm parameters of the ReachDSL
ports on the 8312/8314 ReachDSL/MVL card. Each ReachDSL port is configured
separately.
NOTE: For other types of port cards, refer to the appropriate section in this table.
Action
– Edit/Port Reset/Link Reset. Use Edit to configure the ReachDSL ports. Use Port
Reset to reset the port and make port changes active. Use Link Reset to reset the port
and make link encapsulation changes active.
Port Name
– Enter 1–12.
State
– Port state. This field is read-only.
SN Type
– Enter 6310, 6350, or 6351 (Default = 6351). This field determines the
available Max Speed, Tx Power, Voltage Drop Thresholds, and Link Encapsulation
selections. Use Ctrl-v for a pop-up menu with available selections.
Max Speed
– 0/768/704/640/576/512/448/384/320/256/192/128 kbps (Default = 768). If
the SN Type is 6350 or 6351, speeds of 960/896/832 are also valid. The 0 selection
mutes the transmitter and prevents the line from coming up.
Behavior
– Adaptive. In rate adaptive mode, the rates will vary between the minimum
and maximum speeds as the transmission characteristics of the loop change. This field is
read-only.
Link Encapsulation
– Determines the protocol to be run on the selected port.
(Default = EtherHDLC). Use Ctrl-v for a pop-up menu with available selections. Choose
from the following:
– EtherHDLC for IP packet applications
– FUNI/MPOA for 8314 cards only with a 6351 endpoint
NOTE: If you select FUNI/MPOA, the endpoint must be configured for routing only,
otherwise the line will fail to come up and a SYSLOG message will be generated.
On-hook Tx Power
– 10, 7, 4, 1, –2 dBm (Default = 10 dBm). If the SN Type is 6350 or
6351, TX Power of 12 dBm is also valid. The transmit power level used for the on-hook
state. Both the AN and the SN will use the same value. If the maximum allowable speed is
between 128 and 448 kbps, the already low cross-talk levels may be reduced even more
by lowering the on-hook transmit level.
Off-hook Tx Power
– 7, 4, 1, –2, –5, –8, –11 dBm (Default = 7 dBm). If the SN Type is
6350 or 6351, TX Power of 10 and 12 dBm are also valid. The transmit power level used
for the off-hook state. Both the AN and the SN will use the same value. For short loops
(7000 feet or less), analog phone noise may be reduced and analog modem performance
enhanced by reducing the off-hook power of the ReachDSL/MVL transmitters in both
directions.
