When removing a RAC from a powered INU, always the disengage
the RAC from the backplane before disconnecting its ODU cable.
Similarly before inserting an RAC, always reconnect the ODU cable
before engaging the backplane.
An INUe can be fitted with a maximum of six RACs for one of the
following combinations:
• Six non-protected links
• One protected/diversity link plus four non-protected links
• Two protected/diversity links plus four non-protected links
• Three protected/diversity links
DACs can be fitted singly or in combination to provide a mix of
interface types and capacities provided they have a common
backplane configuration. The backplane can be set for E1, DS1, DS3,
or STM1/OC3. Mux version DACs allow a mix of interfaces from a
common E1 or DS1 backplane configuration.
To achieve a greater node capacity, two or more INUs can be
interconnected via a DAC option.
Ensure correct orientation of the Mini RJ-21 connector before pushing
it home. This can be checked by the scalloped key to one side of the
connector. Additionally, a trib cable supplied by Alcatel9500 MXC
CT will have the cable exiting to the right side when viewed from the
front.
Ensure the connector retaining screws are not over-tightened - only
use light/moderate screwdriver pressure.
The maximum drop, through plus drop, or through capacity of a 9500
MXC Node comprising one INU/INUe is one of the following,
depending on the backplane setting:
• 100x E1
• 128xDS1
• 6xDS3
• 2xSTM1/OC3
