1643 Access Multiplexer AM/1643 Access Multiplexer Small AMS system overview

The 1643 AM/1643 AMS are high capacity, flexible and cost-effective wideband multiplexers which can multiplex standard PDH and SDH bit rates as well as Ethernet signals to line transport rates. These systems are useful elements in building efficient and flexible networks because of their wide-ranging in capacity in addition to a compact and flexible design.

The standard 1643 AM/1643 AMS without option card is capable of multiplexing up to sixteen 2 Mbit/s signals into an STM-1 or STM-4 signal. The equipment is available unprotected or with 1+1 MSP protection (with STM-1 aggregate only) in terminal applications and SNC/N protection for ring applications.

The main board can be upgraded with one of eleven option cards as described in Chapter 4, Product description and thus be adapted to special network requirements.

The standard 1643 AMS is capable of multiplexing up to sixteen DS1 or E1 (depending on the version) signals into an STM-1 signal. The equipment is available unprotected or with 1+1 MSP protection in terminal applications and SNC/N protection for ring applications. The main unit comprises 16 DS1 or 16 E1 interfaces and 2 STM-1 optical line interfaces. The optical line interfaces can be equipped with various SFPs (Small Form-factor Pluggable units). All SFPs are equipped with LC connectors. For the STM-1e interfaces 1.0/2.3 coax connectors are used. Additionally the main board can be upgraded with one of eight option cards as described in Chapter 4, Product description.

1643 AM

The 1643 AM is an SDH STM-1 or STM-4 Terminal or Add-Drop-Multiplexer optimized to provide various tributary services, e.g. STM-1, 1.5 Mbit/s, 2 Mbit/s, 34 Mbit/s, 45 Mbit/s, X.21, SHDSL and 10/100BASE-T, to business and residential customers. The main card is able to multiplex tributary signals into a 155 Mbit/s (STM-1) or a 622 Mbit/s (STM-4) optical aggregate signal. The system provides the ability to add one option card. In the access network, the 1643 AM can be installed at the customer premises for fiber-to-the-business applications, or taking into account the large temperature range, in street cabinets for fiber-to-the curb applications enabling a variety of configurations. Other applications include LAN-to-LAN traffic on campus networks or WANs.

The space-efficient design of 1643 AM allows for wall, rack or desk mounting; please refer to the 1643 Access Multiplexer AM/1643 Access Multiplexer Small AMS Installation Guide.
