1+1 Hot Standby link with in-band management
In Band management provides a single network which multiplexes customer data with
management data. Please refer to Management network on page 1-43 for more details of
this mode.
When In Band is configured, the Ethernet Switch must provide two ports to carry the
traffic to the two CMUs. The choice of physical medium can be copper or fiber and this can
be selected independently for each CMU. This arrangement is shown in Figure 61.
For correct 1+1 Hot Standby operation, the two CMUs must also be connected together
over the protection interface. Please refer to Protection cable on page 4-17.
