Metropolis® AMU.

Multiplexer of the access Of metropolis® AMU

The family of the multiplexers Of metropolis of the company Of lucent Of technologies, was supplemented by a new series of devices. Metropolis® AMU - compact multiplexer of the access of level STM-1 or STM-4 (with the declared support of level STM-16) for the sake of the high density of ports making possible at the point of the operators of connection to allow the reliable, highly productive and high-speed communication line services, such as:
the connection of remote from each other down tens of kilometers local networks, guarantee of Internet access, the transfer of the channels of telephony.
These devices can be used as the multiplexers of input/output (ADM), terminal multiplexers (TM), or the device of local crosscountry race -[konnekta] (LXC).
The multiplexers Of metropolis® AMU make possible at the point of operator to build different diagrams of the organization of connection, such as: “point- point”, annular connection, and also access to the ring. The wide spectrum of interfaces (optical STM-1, STM-4 GbE together with the electrical E1, E3, FE, GbE, SHDSL) on one communication line platform they make it possible to transfer as far as the existing networks SDH vocal traffic TDM (including interstation connections across the channels E1) and traffic of data Of ethernet up to Gigabit Of ethernet. The family Of metropolis® AMU is positioned for the application before the networks of access or before the territory of subscriber (CPE), and it occupies before a number of the multiplexers Of metropolis the place between the models Of metropolis® AMS and Metropolis® ADM Of compact. The appearance of this device before the rule of the products Of metropolis they made it possible to substantially increase flexibility and effectiveness of proposed Lucent Of technologies of the net solutions.

The systems Of metropolis AMU are delivered before two versions:
1- howl version. Metropolis® AMU (2m/4o)

Chassis of 2m/4o, has for the connection six slots (two aggregate and four [tributarnykh]) is optimized for the use on the regional center for the sake of the high capacity of the connection of the [tributarnykh] flows of the transfer of services to connection and maintenance of different diagrams of shielding redundancy SNCP, MSP and instrument room 1+1.

Versions of the organization of the block diagrams of connection for the sake of the use Of metropolis® AMU.
Metropolis® AMU supports the large number of versions of configurations for the organizations of communication networks:

Linear and annular structure of the network
Organization of connection according to diagram “flat ring”
Two annular networks [soedinennye] through one (or two) Metropolis® AMU
Annular structure with the offshoot of the linear networks
GSM/UMTS of communication networks, and others.

	Structure of connection “point- point” without the redundancy MSP.
	Structure of connection “point- point” c by redundancy MSP.
	Linear structure of the connection of the elements of network for the sake of the redundancy MSP
	Linear not [zashchishchennaya] diagram of the organization of connection. This diagram should be used with the building, when price factor is one of the basic criteria, namely: the corporate networks LAN-LAN of [udalennykh] from each other office buildings, business- centers. This solution makes it possible to use equipment Of metropolis AMU before the minimum assembly, and to also economically use [optovolokno] before the cable.
	Organization of connection according to diagram “flat ring”. In comparison with the linear not [zashchishchennoy] diagram of the organization of connection, this diagram ensures the additional reliability of the protection of the transferred traffic. So this diagram makes it possible to use free fibers before the network for the connection of different shielding (backup) ways of the transfer of traffic for the circuit of the basic [povrezhdennoy] (or reconstructed) main.
	Annular structure of network. Annular structure with the possibility of the transfer of the aggregate flows of level STM-1 or STM-4 with the use of shielding switching of the passage of net traffic SNCP (component signals - E1, Ethernet of 10/100 Base T).
	Dual [koltso].[Predstavlyaet] by itself the diagram of connection of two annular networks STM-1 and STM- N, through the main distributive element of the network Of metropolis® AMU.
	Schematic of the organization of the connection of two annular networks of [soedinennykh] through two main multiplexer stations Metropolis® AMU. The diagram in question can be more preferable in comparison with the connection diagram through one main multiplexer station when the creation of annular network STM-1 or STM-4 can be hindered by geographical factors. Diagram is more [zashchishchennoy] t [k] it has two railroad junctions, also, in the case of damage to one of them, the disturbance of the transfer of traffic does not occur because of the additional apparatus redundancy. It permits implementation of a passage based on the annular [zashchishchennoy] structure of the low level of aggregate signals to the ring with the higher aggregate speeds.
	Ring circuit with the expansion from the connected linear networks of the organization of connection. This is an example of the economical solution as far as the propagation of the flows of linear signals E1, 10/100Base T. moreover, linear network can be with the shielding redundancy and without it.
	Main diagram. Diagram of the organization of connection for the sake of use of one of the elements as the main flux concentrator SDH, PDH and Ethernet of 10/100 Base T. the standard the schematic of the use as the main element of a multiplexer Of metropolis® AMU of 2m/4o, and before the connected down it stations (client part) - Metropolis® AMU of 1m/1o.
	Example to the distribution network of that using different capabilities of the multiplexer equipment Of metropolis® AMU on the organization of connection.
