Operations interfaces
The Metropolis
®
AMU offers a wide range of operations interfaces to meet the needs
of an evolving Operations System (OS) network. The operation interfaces include:
•
Q-LAN interface
The Q interface enables network-oriented communication between Metropolis
®
AMU systems and the element/network manager. This interface uses a Qx interface
protocol that is compliant with ITU-T recommendation G.773-CLNS1 to provide
the capability for remote management via the Data Communication Channels
(DCCs). The Q-LAN connector is either a 10 Mbit/s or 100 Mbit/s (10/100
BASE-T) connector with automatic MDI/MDIX selection.
•
F interface for a local PC
One RJ-45 F-interface is provided, at the main board of the Metropolis
®
AMU
This interface provides operation access for a locally installed PC, the Craft
Interface Terminal (ITM-CIT)
•
USB interface
The Metropolis
®
AMU provides two USB 1.1 interfaces labelled USB 1 and USB
2. Each external USB interface provides upto 500mA at 5V to power external
devices. An overcurrent circuit protects the power outputs in case of short circuits;
the overcurrent condition can be read by the ITM-CIT. The USB controller also
supports 4 internal USB 1.1 ports which are used as control and management
interfaces via the backplane towards the tributary slots. The USB interface is
realized with a USB connector and is only used for internal system communication.
•
G-LAN interface
The Metropolis
®
AMU provides a G LAN interface to connect to the Ethernet port
of the PC (on which the Fast Download Tool is installed) for quick software
download. The G LAN interface supports the automatic MDI/MDIX function, so
no crossover cable is needed.
•
Miscellaneous Discrete Interfaces
The Metropolis
®
AMU provides 4 Miscellaneous Discrete Inputs (MDIs) and 4
outputs (MDOs). The MDIs can be used to read the status of external alarm points,
for example, power supply detectors, open door detectors or fire alarm detectors.
The MDOs indicate the alarm status of the equipment and drive external signalling
devices. Labels can be associated to an MDI. An MDO can be coupled to an alarm
event.
