MW-SDH IDU

Standard PDH 1+0

Configuration

SDH 1+0 Configuration

• Part number: IDU-SO (STM-1 Optical, 1+0) or IDU-SW (STM-1 Electrical, 1+0)

– Consists of

– Chassis, Backplane

– 5 modules

• CCM-4800: Power Supply Module

• CCM-4500: Controller Module

• CCM-4100: Standard I/O Module

• CCM-4600: Modem and IF/Telemetry Module

• CCM-4155 or -4156: STM-1 Optical or Electrical Mini IO Module

SDH 1+0 Configuration• SDH 1+0 Capability: IDU-SO (STM-1 Optical, 1+0) or IDU-SW (STM-1 Elect

rical, 1+0)

• Dependent on available bandwidth: can adjust for operating bandwidth

– Payload Options (hardware is always available in unit)

• 100BaseTX Ethernet: scalable (from 1 – 100 Mbps)

• 1-16 x E1/T1: 2 x E1 (RJ-48C), 14xE1 (Molex 60-pin high density)

• STM-1 Optical or Electrical

• Skyway’s “Mode Configurator” tool to create any combination (assuming av

ailable bandwidth)

– Examples include

• STM-1 + 1 Mbps scaled Fast Ethernet

• STM-1 + 1 E1

• Other combinations that allow operation in 28/30 MHz bandwidth

SDH 1+1 Configuration

• Part number: IDU-SO (STM-1 Optical, 1+1) or IDU-SW (STM-1 Electrical, 1+1)

• Consists of

• Chassis, Backplane

– 7 modules

– CCM-4800: Power Supply Module, Qty2 each (for redundancy)

– CCM-4500: Controller Module

– CCM-4100: Standard I/O Module

– CCM-4600: Modem and IF/Telemetry Module, Qty2 each (for redundancy)

– CCM-4155 or -4156: STM-1 Optical or Electrical Mini IO Module

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

Multi-hop Repeater with D/I Config

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)

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

IDU: Options – PDH (IDU-PB 1+0) to Super PDH

s pointand- click selection of pr

edefined routings or custom rou

ting.

• Custom routing selections may

be uploaded to the IDU via FTP.

16/32 E1 Crosspoint Capability

• Add/Drop Example: E1/T1s may be dropped from east or west to the front-panel ports.

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)
