DAC ES supports three operational modes, transparent, mixed or VLAN:

This
supports four customer connections (ports 1 to 4) with bridging to two separate
transport channels (C1 or C2).
Transparent Mode Port and Channel Assignment
Figure 3-30.
Use only C1 or C2 over the same radio or fiber path. C1 and C2 may be used to
support two back-to-back links where each channel is assigned to its own RAC
(or RAC and DAC 155oM). Transparent Mode is applicable to ring networks
using 9500 MXC ring-wrap protection, with one channel is assigned to the east,
the other to the west.
Mixed Mode
Mixed Mode supports two network interconnections where P1-C1 provides
dedicated transport for P1 traffic. A second transparent/broadcast mode
connection is provided with P1, P2, P3 and C2 interconnected.
Mixed Mode Port and Channel Assignment
Figure 3-31.
The two channels can be assigned on the same link or used to support separate
links. Mixed Mode is particularly applicable to east and west links in an IP ring
where alternate-path protection is provided by an external RSTP switch.
