Internal bus
For the controller sub–system the following buses are defined:
"Management bus" that allows:
•
– connection between SC and boards for configuration data provisioning
– remote inventory data acquisition
– data collection (alarms) and commands handling (example: loops)
"ISSB bus" used for communication among the Equipment Controller, the Shelf
•
Controllers and the Local Microprocessor.
External interfaces
F interface - It is available from the EC function for connection to a local Craft Terminal;
the electrical interface and connector (both RJ45 and mUSB) are provided by the EC320
card.
M interface - It is dedicated to an OS station connection. The M interface can be
supported for the connection to a WAN or LAN respectively.
The M requires a 10BASE2 or a 10BASET interface.
M-remote interface - It is a TMN related communication interface based on the use of
the Embedded Communication Channels. Through the M-remote interface the system can
exchange management messages with a remote OS. In the Alcatel-Lucent 1850 TSS-
320/160 up to three full duplex ECC channels can be terminated from each SONET
interface: one DCCM at 576 kbit/s, one DCCR at 192 kbit/s and one DCCP 64 kbit/s.
RE / HK interface - this interface consists of parallel I/O signals used for remote alarms
and for housekeeping signals. The relevant electrical interfaces are placed on the Alcatel-
Lucent 1850 TSS-320/160 interconnections panel and are controlled by the EC function
through parallel I/O ports.
RA interface - it is dedicated to send commands towards the rack to light up the relevant
lamps located on GENTRU unit. Examples of network management architecture are
reported in
these figures any generic SONET and DATA equipment (Add / Drop Multiplexer, Cross-
connect, Regenerator, etc.) inserted in the network is indicated by the acronym NE
(Network Element).
Network management interfaces
The SONET Equipment provides two types of physical interfaces for management
functions: the F interface and the Q3 interface. These interfaces can be connected to the
manager computer, that are:
A Personal Computer connected through the F interface for local management.
•
OPERATION SYSTEM (OS). Workstations utilized for the TMN
•
(Telecommunications Management Network). They are connected through the M
interface, for network management.
