3.17. BC2312. Dual AES 10 MADI module for linking racks with SFP
transceivers.
General description.
The BC2312 board manages up to 128 TDM bus time-slots to send and/or receive them
through two 125-Mbps MADI multichannel digital audio links using coaxial or optical fiber cable
(through SFP - Small Form Pluggable transceivers). These two MADI links are independent.
This board allows you to interconnect up to three BC 2000 D racks (you can use each of the two
MADI links to connect to other 2 BC2312 boards placed in different racks), or to connect any
other MADI equipment item. It is compliant with the AES-10 standard.
You can install two modules with the same link for redundancy purposes or you can use both
links of the board redundantly (link 2 acts as a backup for link 1).
This board is inserted into the rear part of the BC2000DF rack.
Panel description.
'HW ERROR' red LED: this LED will turn on when the
system starts and, depending on its status, it will indicate
during normal operation:
-
Configured and active board: fast blinking.
-
Configured and active board extracting synchronism:
discontinuous fast blinking.
-
Not configured board: slow blinking.
-
Board start error: LED on and fixed.
-
Board configured in backup mode: LED off.
-
Board configured in backup mode extracting
synchronism: LED off with discontinuous on status.
1.6-5.6 'SYNC OUT' female coaxial connector: word-clock
synchronism output with TTL level.
'Rx LOSS' red LED: indicates an alarm in the optical fiber
receiver because no reception signal is detected.
'Tx FAULT' red LED: indicates an alarm in the optical fiber
transmitter.
LC 'Rx' and 'Tx' connectors*: SFP (Small Form Pluggable)
optical fiber transceiver, removable and interchangeable
without tools.
1.6-5.6 female 'Rx' and 'Tx' coaxial connectors: 75-ohm
coaxial cable interface with a range of 50 meters.
'Rx LOSS' red LED: indicates an alarm in the optical fiber
receiver because no reception signal is detected.
'Tx FAULT' red LED: indicates an alarm in the optical fiber
transmitter.
LC 'Rx' and 'Tx' connectors*: SFP (Small Form Pluggable)
optical fiber transceiver, removable and interchangeable
without tools.
1.6-5.6 female 'Rx' and 'Tx' coaxial connectors: 75-ohm
coaxial cable interface with a range of 50 meters.
*It’s possible to use any 125Mbps OF SFP transceiver
monomode or multimode. The maximum range that can be
reached is 2Km for MULTIMODE fiber and more than 150Km
for MONOMODE fiber.
