Oms 1200 Stm1/4 Core Card - Ericsson Marconi OMS 1200 Product Description

With core cards, addition of a second core card automatically provides equipment –
level protection against card failure. Failure/removal of a core card means that its SDH
line interface functions are also lost. For full protection, therefore, the SDH line
interface functions of a second core provide protection for those equivalent functions
of the first core, all configured as inter-core-card MSP protection pairs. However there
is no restriction to this allocation, and any pairings are allowed for 1+1 Linear Trail
MSP. For example:
•
•
•
STM-16/4 core cards only provide one SDH line interface function, therefore if this
needs MSP protection configuration, then two core cards have to be installed with
inter-core-card MSP protection pairing.

OMS 1200 STM1/4 Core Card

STM-1/4 core cards provide two STM-1/4 line interfaces. These may all be configured
to operate as unprotected ports on a hubbing NE.
When two Core Cards are fitted; the second core card automatically provides
equipment level protection against card failure. The second core can also be used to
provide protection for the SDH line interface functions utilising inter-core-card MSP.
There is no restriction to the allocation, any pairings are allowed for 1+1 Linear Trail
MSP. For example:
