Data Communications Channel (DCC)
Provisioning the DCC
To support remote operations over the DCC embedded in the SONET section overhead of the optical signal, the DCC itself must be provisioned as indicated in the following paragraphs.
DCC enable/disable
By default, the DCC is enabled on all optical ports. DCC communications can be enabled or disabled on each port independently.
DCC protection mode
The DCC protection mode is determined by the transmission protection mode assigned to the high-speed (main OLIUs) optical port (per the application parameter). The protection mode can be linear (1+1) identical, or distinct (UPSR). UPSR is the default for the high-speed optical ports.
User side and network side
The operation of each DCC span also depends on one end of the span being designated the "User" side and the other end being designated the "Network" side. The DCC User/Network side assignments are provisionable.

Notes:
Because DCC is disabled on the corresponding 0x1Sn inactive port, this provisioned value has no effect.

DCC compatibility
Alcatel-Lucent 1665 DMXtend supports the optical interfaces with DCC communications compatibility as shown in the following table. Alcatel-Lucent 1665 DMXtend supports Section DCC running the OSI protocol stack and IP. The “1+1” entries represent linear and bidirectional (1+1) protected DCC compatibility.
