3. DSL Card Configuration
8000-A2-GB26-50 April 2001
3-11
DSL Ports (DSL Parameters) 8310/8312 MVL Card A-B-B
8314 MVL Card A-B-A
Provides the ability to configure the operational and alarm parameters of the MVL ports
on the 8310/8312/8314 card. Each MVL port is configured separately.
NOTE: For other types of port cards, refer to the appropriate section in this table.
Action
– Edit/Reset. Use Edit to configure the MVL ports. Use Reset to reset the port and
make changes active.
Port Name
– Enter 1–4 for 4-port 8310 cards, 1–12 for 12-port 8312/8314 cards.
SN Type
– Model number of the service node. This field is read-only.
Max Speed
– 0/768/704/640/576/512/448/384/320/256/192/128 kbps (Default = 768).
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.
Link Encapsulation
– Indicates the protocol running on the selected port. This field is
read-only.
On-hook Tx Power
– 10, 7, 4, 1, –2 dBm (Default = 10 dBm). 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). 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 MVL transmitters in
both directions.
Margin Threshold
– Sends a trap message if the margin on either end falls below the
selected value. Enter a value for the margin threshold trap (–5 dB to +10 dB)
(Default = +3). Enter D to disable trap.
Link Down Ct
– Sends a trap message if the number of MVL link down events in
15 minutes exceeds the selected value. Enter a value for the Link Down Count Trap
(0–1000) (Default = 0). Enter D to disable trap.
