Optical, 1+0) or IDU-SW (STM-1 Electrical, 1+0) Dependent on
available bandwidth: can adjust for operating bandwidth Payload

2+0 or East/West Configuration Consecutive point architecture
achieved with only a single 1 RU chassis at each location In this
configuration the IDU contains 2 Power Supply Modules and 2
Modem/IF Modules One Modem/IF is referred to as the west modem and
the other as the east modem The IDU is connected to two ODUs, one
broadcasting/receiving in one directing of the ring architecture
and the other broadcasting/receiving in the other direction
Slide 12
This configuration provides individual 1 + 1 link protection as
well as the full-scale protection inherent in the consecutive point
architecture At each location within the network, data may be
dropped or inserted Front panel connections for drop/insert
capability are provided In this configuration each IDU contains 2
Power Supply Modules and 2 Modem/IF Modules Multi-hop Repeater with
D/I Config
Slide 13
1+1 Protection: Diversity Diversity mode: the link between each
pair of modems is the same, providing complete redundancy This
arrangement requires bandwidth for both links and non- interference
between the links, but it provides hitless receive and transmit
switching The IDU supports both frequency and spatial diversity
Frequency diversity: two frequencies are used Spatial diversity:
two non-interfering paths are used In either case, the proprietary
framer chooses the best, or error-free, data stream and forwards it
to the Line Interface Units (LIUs)
Slide 14
1+1 Protection: Non-Diversity Non-diversity mode: One ODU at
each location transmits to both two ODUs at the other location Does
not require the extra bandwidth or interference protection of
diversity mode Provides hitless receive switching and hot standby
IDU automatically switches transmit ODU upon appropriate ODU alarm
or ODU interface error, minimizing transmit outage time The power
supply, ODU, IF/telemetry and modem are protected The digital
framing and LUIs are not

uploaded to the IDU. Mappings are selected on the IDU via a
drop-down box. Up to 32 pre-defined (via Excel) mappings may be
specified A custom mapping can be edited directly on the IDU

The IDU cross point switch provides any-to-any E1/T1 routing
between the front-panel ports, east and west RF links. Flexible
channel mapping allows pointand- click selection of predefined
routings or custom routing. Custom routing selections may be
uploaded to the IDU via FTP. 16/32 E1 Crosspoint Capability

The IDU STM-1 Mux/Demux provides capability to demultiplex
63xE1 (84xT1) PDH signals from the SDH signal. The demultiplexed
E1/T1s are routed via the crosspoint switch to east, west, or
frontpanel. Enhanced IO (CCM-4120) Module is required for this
function Scalable SDH STM-1 Mux/Demux Capability
