• DAC 155oM supports fiber link capacities to 129 Mbps for both Nx 2 Mbps
or Nx 1.5 Mbps capacity types.

Operational Mode
: Select Transparent, Mixed or VLAN mode for the
Ethernet bridging-switching function. Transparent mode supports layer 2
(L2) link aggregation with options for channel and channel/port aggregation.
For information on link aggregation options and operation refer to Link
Aggregation on page 7-76.

is the default, broadcast mode;
all ports and channels are interconnected. It supports four customer
connections (Ports 1 to 4) with bridging to two link transport channels
(C1and C2). For single link applications select only C1 (or C2) to avoid a
traffic-loop.

Transparent with Aggregation .
Click Edit Aggregation to view and set the
aggregation options. The options provide selection of the channels and/or
ports to be aggregated.
A channel selection applies where C1 and C2 to are each to be mapped to a
RAC or DAC 155oM in the same INU/INUe as the DAC GE.
A port selection applies where the link or links to be aggregated are installed
on one or more co-located INUs. A port-port Ethernet cable is used to
interconnect the assigned DAC GE ports on the INUs.
Aggregation weighting refers to the way the aggregation keying process
allocates traffic between the aggregated link grouping. 16 keys are provided
and traffic is randomly assigned to a key. With two aggregated links of equal
capacity the weighting (number of keys) should be split 8/8. With three
aggregated links of equal capacity the split should be 5/5/6. The aggregation
weights must be assigned such that they always total 16.
RAC modulation/bandwidth and Node license must support the channel capacity
selected within the DAC GE plug-ins screen.
