2+0 or East/West Configuration• Consecutive point architecture achieve
d with only a single 1 RU chassis at ea
ch location
• In this configuration the IDU contains 2
Power Supply Modules and 2 Modem/I
F Modules
• One Modem/IF is referred to as the we
st modem and the other as the east m
odem
• The IDU is connected to two ODUs, on
e broadcasting/receiving in one directi
ng of the ring architecture and the othe
r broadcasting/receiving in the other dir
ection

• 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

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-interfer
ence between the links, but it provides hitless receive and transmit s
witching
– 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)
![Page 14: Microwave SDH Product Line](https://reader030.fdocuments.us/reader030/viewer/2022020106/563dbb53550346aa9aac2e43/html5/thumbnails/14.jpg)
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 O
DU interface error, minimizing transmit outage time
• The power supply, ODU, IF/telemetry and modem are protected
• The digital framing and LUIs are not
