PBUS The PBUS contains signals for synchronization, distribution of PDH signals, and internal communication. COGE5 and all service units have access to the PBUS in order to exchange information using the KEYMILE proprietary protocol ICN (Internal Communi- cation Network). The ICN is used for the management communication between the core unit and service units within the subrack.

When inserting a COGE5 unit the first time into a XMC20 subrack the unit is running in the network element bootloader, no ESW is installed. You need to install valid ESW on the COGE5 unit in slot 11. If you implement core unit redundancy, you need to install the identical ESW on the COGE5 units in both slot 11 and slot 13.
COGE5, COGE5-F Configuring an Ethernet Front Port In order to configure one of the Ethernet front ports in COGE5, the following steps have to be performed. If you are using a redundant COGE5, the steps must be performed on both COGE5, the active core unit (unit-11) and the standby core unit (unit-13).
COGE5, COGE5-F Operation and Maintenance This section presents how to operate the COGE5 unit once it has been com- missioned. For a description on how to configure and bring into operation the COGE5 unit and its main functions, refer to section 6 Commissioning page 50).

- In the waiting state the control unit is waiting for configuration. The waiting state lasts as long as the COGE5 has no configura- tion. In this state, the COGE5 can only provide the “point to point” type of management communication. This means that only the Ethernet local management port will allow a direct connection for initial commissioning.

Risk of operating trouble! The assignment of new unit ESW or network element ESW to COGE5 requires a restart of the unit. → Thus, the installation of new ESW on the COGE5 unit affects all traffic functions.
