The XDM -100 boasts an extremely high modular structure in several main shelf
configurations:
Basic XDM-100 shelf with two MXC (Main Cross-connect and Control)
♦
cards for supporting system redundancy.
Expanded XDM-100 with I/O protection. A Tributary Protection Unit (TPU)
♦
is mounted on top of the basic shelf providing protection to the I/O modules.
Nonredundant XDM-100 configuration. The shelf comprises only one MXC
♦
card. Therefore, redundancy for all functions provided by the MXC is not
supported.

7.1 XDM-100 Shelf Configurations

7.1.1 Basic XDM-100 Shelf

The basic XDM-100 shelf is housed in a 231 mm deep, 443 mm wide, and 200 mm
high equipment cage. The lower part of the shelf consists of the card cage and
accommodates the MXC cards (main and protection) and the External Connection
Unit (ECU). The upper part of the shelf consists of the module cage and houses up
to eight I/O modules. Various types of interface modules supporting PDH/Async,
SDH/SONET, and data services are available.
All electrical connections are located directly in the tributary modules; therefore, the
XDM-100 does not need additional electrical interface connections.
To support system redundancy, each MXC card contains an integrated XDM Input
Filter (xINF) unit with connectors for two input power sources.
