Parameter Function Values
Auto
Negotiation
Controls the use of auto-negotiation
for the selected Ethernet port.
Auto-negotiation is used to select
automatically the mode providing the
highest possible traffic handling
capability
ENABLE – Auto-negotiation is enabled. This is the
normal operation mode.
DISABLE – Auto-negotiation is disabled. This mode
should be used only when the equipment connected
to the port does not support auto-negotiation.
Default: ENABLE
Max. Capability
Advertised
When Auto Negotiation is ENABLE,
selects the highest traffic handling
capability to be advertised during the
auto-negotiation process. The
operating mode selected as a result of
auto-negotiation cannot exceed the
advertised capability.
When Auto Negotiation is DISABLE,
this parameter is replaced by Speed &
Duplex
The available selections are listed in ascending order
of capabilities:
100Mbps full duplex – Full-duplex operation at
100 Mbps.
100Mbps half duplex – Half-duplex operation at
100 Mbps.
10Mbps full duplex – Full-duplex operation at
10 Mbps.
10Mbps half duplex – Half-duplex operation at
10 Mbps.
Default: 100Mbps full duplex
Speed &
Duplex
When Auto Negotiation is DISABLE,
selects the data rate and the
operating mode of the selected
Ethernet port.
When Auto Negotiation is ENABLE, this
parameter is replaced by Max.
Capability Advertised
Same selections as for the Max. Capability
Advertised parameter.
Default: 100Mbps full duplex
Flow Control Controls the use of flow control for
the selected Ethernet port (when
operating in the full duplex mode), or
back pressure (when operating in the
half-duplex mode)
ENABLE – Flow control or back pressure is enabled.
In this case, when the offered Ethernet traffic
exceeds the available transmission bandwidth, the
port forces the source to reduce its traffic volume.
DISABLE – Flow control and back pressure are
disabled.
Default: DISABLE
3.7 Configuring Ethernet Services
LRS-102 Ethernet services are supported by configuring flows within the LRS-102
(flows are a generic type of Ethernet virtual connections that interconnect
user-specified bridge ports).
Two types of bridge ports can be defined on an ASMi-54C module:
• Each PCS configured on the module SHDSL ports.
• Each Ethernet physical port can also serve as a bridge port.
