7.3 Main Cross-Connect and Control (MXC)
and External Connection Unit (ECU) Cards
The XDM-100 MXC and ECU cards were designed to facilitate simple installation
and maintenance. They feature:
♦
Electrical interface connectors that are integrated into the I/O modules,
saving the need for separate electrical interface modules
♦
Easy routing of external management interfaces
♦
A monitoring system for acceptance test purposes
♦
Hot insertion of cards and modules to support quick maintenance and repair
activities, without affecting traffic
7.3.1 MXC
Cards
The basic and expanded versions of the XDM-100 shelf accommodate two identical
MXC cards. By default, the MXC-A is the main card and the MXC-B is the
protection card. Both cards perform the following functions simultaneously in a 1+1
protection configuration:
♦
Communications and control
♦
Alarm and maintenance
♦
Cross-connect
♦
Timing and synchronization
♦
Distribution of power supply to all modules (xINF function)
♦
Routing and handling of 32 DCC channels
In addition, the MXC accommodates the NVM compact flash memory card and
houses SDH/SONET aggregate modules (SAMs).
The additional MXC card provides 1+1 protection to the cross-connect matrix and
full 1:1 protection to all other functions, since the standby MXC has an identical
database to the active MXC.
In case of a hardware failure in the active MXC or its traffic interconnection, the I/O
interface modules switch to the protection MXC within 50 ms. Similarly, in case of
a hardware failure in the TiMing Unit (TMU) of the operational MXC card, the
backup TMU takes over the timing control with no disruption in traffic. The
operational MXC card is configured by eNM LightSoft™, ECI Telecom’s Optical
Network Division’s multidimensional network manager.
