Installing the IDU in a Nodal Enclosure
Each IP-10 IDU in a nodal configuration operates as either the main unit or an
extension unit. The IDU’s role is determined by its position in the nodal
enclosure, with the lowest unit in the enclosure (Unit Number 1) always
serving as the main unit.
The main unit performs the following functions:
Provides a central controller for management
Provides radio and line interfaces
Extension units provide radio and line interfaces, and are accessed through
the main unit.

Nodal Enclosure Design
Two types of shelves are available for a nodal configuration:
Main Nodal Enclosure
– Each node must have a main nodal enclosure,
which can hold two IP-10 IDUs.
Extension Nodal Enclosure
–Up to two extension nodal enclosures can be
stacked on top of the main nodal enclosure. Each extension nodal
enclosure can contain two IP-10 IDUs.
Main Nodal Enclosure
Extension Nodal Enclosure
Each nodal enclosure includes a backplane. The rear panel of an IP-10 IDU
includes an extra connector for connection to the backplane. The following
interfaces are implemented through the backplane:
Multi-Radio
Protection
XPIC
IP-10 IDUs are hot-swappable, and additional extension nodal enclosures and
IDUs can be added in the field as required, without affecting traffic.
