Hardware description 1643 AMS

The 1643 AMS is a compact and cost-effective STM-1 Add/Drop multiplexer designed

to be installed at the customer's premises for fiber-to-the-business applications. Its

space-efficient design allows for horizontal or vertical wall-mounting within controlled

or non controlled environment locations (for example interior closet) or in street

cabinets. Please refer to the 1643 AM / 1643 AMS Installation Guide for details.

The unit has the following characteristics:

• 70 x 448 x 204 mm (H x W x D) unit size (without wall or rack mounting system)

• main board including:

– Two STM-1 optical aggregate line interface pairs (transmit/receive) for SFP

– 1643 AMS E1 version: Sixteen 2 Mbit/s electrical tributary interfaces (E1) with

– 1643 AMS DS1 version: Sixteen 1.5 Mbit/s electrical tributary interfaces (DS1)

• F-interface (RJ45) complying with V.10/RS-232 for the Craft Interface Terminal

(ITM-CIT)

• Q-LAN interface to connect to the EMS or to other NEs is available with an RJ-45

(LAN-10BaseT) connector

• External Synchronization Output at 2048 kHz (SYNC-OUT) with RJ45 connector

suitable for symmetrical twisted pair cable with an impedance of 120 Ω or coaxial

cable with an impedance of 75 Ω

• Two LEDs (Red, Green) to indicate the status of the unit.

• Four Miscellaneous Discrete Inputs (MDIs) to read the status of external alarm

points, and four Miscellaneous Discrete Outputs (MDOs) to drive external devices

are available from a 25 pin male Sub-D connector.

• The 1643 AMS provides two connectors that allow access to the RS EOW byte E1

or MS EOW byte E2 of the two STM-1 line interfaces.

By default, the 1643 AMS directs the 64 kbit/s data supplied at the input pins of

the EOW connector to the E2 byte of the associated STM-1 line interface. If no

data is supplied, i.e. the connector is unconnected, an all-zeros patterns must be

sent in the E2 byte.

By default, the 1643 AMS directs the 64 kbit/s data carried by the E2 byte of each

STM-1 line interface to the output pins of the associated EOW connector.

• The possibility of power supply of the 1643 AMS is DC power supply or AC

power supply:

– DC power supply is connected to a 9-point male Sub-D 9 connector

– AC power supply is connected to an AC socket (IEC 60320 standard).
