The Metropolis
®
AMU is a high capacity, flexible and cost-effective wideband
multiplexer which can multiplex standard PDH and SDH bit rates as well as Ethernet
signals to line transport rates. In addition to a compact and flexible design, this system
is a useful element in building efficient and flexible networks due to its wide-ranging
capacity.
The 2m/4o version can be equipped with 2 main boards and upgraded with 4 option
cards as described in
Chapter 2, “Product description”
and thus be adapted to special
network requirements. The 1m/1o version can hold 1 main board and upgraded with
one option board. The 2m/4o version holds two slots for main cards where operation
with either one or two main cards is possible. The second main card can be operated
as an additional tributary card or as main card equipment protection. The system
provides the ability to add one option card.
In the access network, the Metropolis
®
AMU can be installed at the customer premises
for fiber-to-the-business applications enabling a variety of configurations. Other
applications include LAN-to-LAN traffic on campus networks or WANs.
The Metropolis
®
AMU MI-16/4 is an SDH STM-1/4 and STM-4/16 Terminal or
Add-Drop-Multiplexer optimized to provide various tributary services such as
STM-1/4, 1.5 Mbit/s, 2 Mbit/s, 34 Mbit/s, 45 Mbit/s, STM-1e, STM-4, 1000BASE-T/X
and 10/100BASE-T, to business and residential customers. The MI-14/4 main card is
an SDH STM-1/4 and STM-1 Terminal or Add/Drop Multiplexer and provides various
tributary services such as STM-1, 1.5 Mbit/s, 2 Mbit/s, 34 Mbit/s, 45 Mbit/s, STM-1e,
STM-4, 1000BASE-T/X and 10/100BASE-T.
The standard Metropolis
®
AMU MI-16/4 main card can be equipped with two
multirate STM-1/4 or STM-4/16 interfaces using SFPs. The Metropolis
®
AMU MI-14/4
main card can be equipped with two multirate STM-1/STM-4 and two STM-1
interfaces. When required, the main card can be equipped with SFPs for STM-1 or
STM-4 single fiber working and STM-1e. The equipment is capable of 1+1 MSP
protection and SNC/N protection.
The space-efficient design of Metropolis
®
AMU allows for wall or rack mounting. For
more information, please refer to the Metropolis
®
AMU Installation Guide.
Applications
The network applications can be found in
Chapter 4, “Planning Network Applications”
Management
The Metropolis
®
AMU is managed by network management systems from Lucent
Technologies. This includes the local craft terminal ITM-CIT which is available for
on-site tasks, remote operations, and maintenance activities. Lucent’s Network
Management Systems or the Lucent NMS enable integrated management of an entire
transport network.
