Description
RJ-45 connector.
For the IDU 20x, IDU300 8x, IDU300 20x and IDUsp 16x, it
provides interconnection between paired IDUs for 1+1
hot-standby protection. Protection switching is not hitless.
For the IDU 300 20xV2 and IDU 155o it provides bus
interconnection between paired IDUs for hot-standby or space
diversity. Tx switching is not hitless, Rx path switching (voting)
is hitless for hot-standby and space diversity operation.
For the IDU 20xV2 it also supports trib expansion
(interconnection) when configured for protected operation with
capacities above 20xE1 / 16xDS1. Traffic from the standby IDU
is routed to the online IDU to support termination of up to
40xE1 or 32xDS1 tribs. In this configuration trib and PSU
protection is not supported, however ODU protection functions
are retained. Capacities above 20xE1 or 16xDS1 require a
capacity license.
For all IDUs, except IDUsp 16x, Tx/Rx online and primary/
secondary status is indicated by the protection connector LEDs
as:
• Green Online LED is on for an online Tx and/or Rx. (Normally
the online IDU is online for Tx and Rx).
• Green Online LED is off for the offline IDU (IDU is not
transmitting or controlling the Rx diversity bus. (Only IDU
300 20xV2 and IDU 155o have a diversity bus).
• Orange Primary LED is on for the primary IDU. (The primary
designated IDU is default online for Tx and Rx).
• Orange Primary LED is off for the secondary IDU.
For the IDUsp 16x the LED indications are reversed, that is the
orange LED indicates online status, and the green LED primary/
secondary status.
RJ-45 connector assemblies for tributary connection; one
RJ-45 port per E1 (IDU 20x) or per E1/DS1 (IDU300 20x /
20xV2). E1 termination is set for unbalanced or balanced in
Portal. DS1 is 100 ohms balanced with options for AMI or B8ZS,
and trib cable length. Cable options provide extension to BNC
connectors for unbalanced, or to RJ-45 plugs or to
unterminated wires for balanced.
SC type single mode optical trib connector assembly.
The receive-level range is -31 dBm (max sensitivity) to -7 dBm
(max input power). Transmit output is within limits of -15 dBm
to -8 dBm.
Cable options are available to provide extensions to SC, FC or
LC connectors.
With protected IDUs, Y-cables are fitted to provide common Tx
and Rx optical interfaces.
