Nortel Golden MI Card NTCA4ABA and NTCA42BA
Maintenance interface NTCA42AA & NTCA42BA

 

Circuit pack descriptions

The maintenance interface (MI) works with the shelf processor. The MI circuit pack contains the RS-232 and the Ethernet interfaces.

Two MI versions are available: the 32 MByte NTCA42AA and the

128 MByte NTCA42BA. The OPTera Connect DX bay supports only the

128 Mbyte MI. The TN-64X bay supports both MI types.

The MI performs the following functions:

• provide access to RS-232 and Ethernet interfaces

• support circuit pack inventory

• collect status signals

• monitor processor sanity

• provide interface between the LCAP and the shelf controller

• provide flash memory storage

• drive bay level alarm indicators

• support a software library

• communicate with the OPC
