6-24 OAM&P description
E1/VC12 management channel
The OME6130 supports up to two management channels that can be
provisioned over an E1 or VC12 channel. The management channel provides
a means to connect to isolated clusters over an E1 or VC12 channel.
An E1 management channel allows management data to be transmitted and
received over the first E1 port of the 28xE1/DS1 circuit pack to manage remote
network element.
A VC12 management channel allows for management data to be transmitted
and received over one VC12 channel on the STM-1/4 interfaces to manage
remote network element.
The E1/VC12 management channel can be configured from the Management
channel application available from the Configuration/DCN menu item in the
local craft access terminal. For more details, refer to Provisioning and
Protection Switching Procedures, 323-1855-310.
DCC interface
The DCC interfaces provide a mechanism for OME6130 network elements
and subtending network elements to communicate and exchange OAM
messages using the RS, MS or HO Path overhead bytes. The embedded
communication channel (ECC) for the STM-1/4 interfaces can be configured
to use any of the following byte groups:
•
•
•
•
The OME6130 supports both IP and OSI based DCC interfaces and can
operate as a single point of entry for access to remote or subtending network
elements using IP or OSI based DCC interfaces. In this release, one IP or OSI
based DCC interface can be provisioned for each STM-1/4 interface on the
OME6130 network element.
The generic routing encapsulation (GRE) protocol is used for OSI based DCC
interfaces. The GRE tunnels can be provisioned statically or dynamically
(auto-GRE tunneling).

Note: Only the first E1 port of the 28xE1/DS1 circuit pack can be used for
the E1 management channel.
Note: In this release, the management channel is supported only over E1
or VC12 channels in SDH mode.
D1-D3 bytes of the Regenerator Section overhead
F1 byte of the Regenerator Section overhead
D4-D12 bytes of the Multiplex Section overhead
F2, F3 or F2-F3 bytes of the HO path overhead
