S.CON1M/MA System
6
In the basic configuration drawing (previous page), any MA device can be connected
to the S.CON1M/MA (H.CON/MA, LTA41/MA, F.CON1/MA). A non-MA device
(S.CON1 or other) can be also connected (although in such case will not be
managed).
Any networking device may connect to the copper port of the S.CON1M/MA
converters: switches/routers (of any type).
While copper segment distance (between the device and the S.CON1M/MA) reaches a
maximum of 100m/330ft, the F/O segment (multi-mode fiber) may be extended to
2000m (6500ft) and much more over single-mode fiber. (Up to 150Km). Single Fiber
Strand (up to 40 Km) can be deployed saving 50 % of the cabling plant.
The S.CON1M/MA supports the
Far End Fault (FEF) feature.
Far End Fault occurs when the signal detection is logically false from the receive
(incoming path) fiber port. When the S.CON1M/MA detects a F/O Link Loss condition,
the unit will automatically send a Far End Fault signal to the remote device. (on it
outgoing path). The remote device should support the same FEF feature and it will
indicate a Link Loss as well. (Refer to chapter 8 for more details).
The S.CON1M/MA supports the
Fault Propagation
mechanism (FO > TP, or/and TP
> FO), selectable through DIP switches (front panel) or
via the management system.
When activated
(FO
> TP
)
if the S.CON1M/MA senses a loss of F/O Link, it will
automatically cut its TP port link. If TP > FO is enable, it will cut the F/O link in case
that the TP port link is disrupted. (See chapter 13 for a detailed explanation).
The S.CON1M/MA supports also the
SLE feature.

mulation virtually emulates the subscriber’s device or
network connected to the TP port of the remote device (H.CON/MA) onto the TP link of
the Master Unit (S.CON1M/MA) connected usually to a switch/router (located in the
Access Node or Network Center).
When activated (
controllable
via the management system only
) it senses the loss
of the TP link connected to the remote MA device, notifies the Master Unit and cuts off
the TP link connected to the switch/router, alerting in real time the switch/router of the
subscriber failure. All this is performed without disrupting the F/O link, thus ensuring
on-going control of the MA remote device via MA.
Two SLE modes of operation are available:
Downstream SLE mode of operation
(link failure of the S.CON1M/MA TP port will
cause the disconnect of the TP port of the attached remote device.)
Upstream SLE mode
(remote device link TP port failure will cause the disconnect of
the S.CON1M/MA TP port).
The aforementioned features make the S.CON1M/MA a reliable and outstanding
device for various and different environments.
