•
The 1-Port STM-1 1+1 MSP Single-mode module is intended for long-
reach applications, typically between LANs. This module is frequently used
to connect high-speed LAN devices (such as routers) to an ATM network,
for voice gateway PRI Offload data aggregation. It is also used to provide a
highly reliable means for interconnection of cell locations in wireless net-
works.
•
The 1-Port STM-1 1+1 MSP Multimode module is intended for short-reach
applications, for example, interoffice or intraoffice sections of a local area
network (LAN).
Two types of STM-1 1+1 MSP modules are available:
•
The STM-1 Single-Mode (SM) 1+1 MSP module is intended for long-reach
applications, typically between LANs up to 25.75 km apart. This module is
frequently used to connect high-speed LAN devices (such as routers) to an
ATM network.
•
The STM-1 Multimode (MM) 1+1 MSP module is intended for short-reach
applications, for example, interoffice or intraoffice sections of a local area
network (LAN) within a radius of 1.93 km.
Software Features
The STM-1 1+1 MSP modules use the
AQueMan™
