1645 AMC main board assembly
The main board has the following characteristics:
• Two STM-1 electrical/optical aggregate line interface pairs (transmit/receive) for SFP
usage
• Two STM-1/ STM-4 optical aggregate line interface pairs (transmit/receive) for SFP
usage
• Sixteen 2 Mbit/s electrical tributary interfaces (E1). The impedance of 75 -120 Ω is
automatically set through the cable
• Supports 33 × 33 / 16 × 16 VC-4s HO/LO non-blocking cross connection capacity.
• E1/E2/F1 access
• Connection facility for tributary interface extensions such as option cards, with a
maximum of 22 × VC-4s HOCC connection capacity
• F-interface (RJ45) complying with V.10/RS-232 for the Craft Interface Terminal
(ITM-CIT)
-LA interface to connect to the EMS or to other Es is available with an RJ-45
•
(LA -10BaseT) connector
• LA interface 10/100BASE-T (G-LA )
• 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.
• Station clock input and output interfaces (RJ-45). (2MHz with 75/120 Ω impedance)
• Hardware reset button
• Power and failure LEDs support.
• A green LED located close to the F type interface connector. The green LED is lit
when the CIT is connected to the E.
• System controller for software control of the transmission hardware on the board
(including optional interface extensions)
ecessary hardware for power supply and processing of transmission signals
•
• The power supply of the equipment is DC or AC power supply.
• Reset button on faceplate for controller reset:
The reset button can be used to soft reboot the unit. The soft reboot does not affect
transmission.
• Manual controller reset via E managers
Other hardware features include:
• An external and approved 110-230 VAC to -48 VDC converter is available as an
option to supply the system with a suitable input voltage.
• On the AMC system, all optical connectors are LC types.
