Option cards

...................................................................................................................................................................................................................................
This chapter describes the option cards which can be used together with 1643 AM /
1643 AMS in order to provide additional interfaces for various data rates or special
applications.
X2S11TRIB/X2STM1ETRIB option card
The different functions of the X2S11TRIB (two STM-1 optical tributary line interfaces)
option card are (see next figure):
• Two STM-1 optical tributary interfaces. One interface is referred to as the "TP2.1",
while the other the "TP2.2".
In case of MSP protection, TP2.1 is the "working" side and TP2.2 the "protection"
side.
Clock and data recovery circuit separates the clock and data signals which are
transmitted to ASIC circuit.
• The circuit ASIC performs :
– In the transmit direction, the circuit ASIC performs the collect of data from the
– In the receive direction, the circuit ASIC performs the STM-1 disassembly, the
– RSOH/MSOH extraction/insertion, DCC processing, VC-4 SNC/N, STM-1 MSP
• Circuit Alarm manager performs:
– reception of different alarms signals from optical interfaces
– dialogue with the microprocessor of the main board.
X2S11TRIB option card
The X2S11TRIB option card provides two optical STM-1 short-haul tributary
interfaces for an 1643 AM equipped with STM-4 line interfaces.
The X2S11TRIB option card is plugged into the P2 connector as described in
view without cover" (p.
The X2S11TRIB option card supports two STM-1 input and two STM-1 output
signals. The physical interface is a universal optical connector which is designed for
standard single mode fibers with an operating wavelength of 1310 nm.
