VCL-STM-1 (upto 63 E1)
The system has two STM-1 optical / electrical interfaces in the
aggregate side and allows for upto 3 tributary add-on cards. The
following tributaries are available as add-on cards for the chassis:
The base chassis houses the following:
STM-1 optical / electrical interfaces are supported depending on
Terminal multiplexer or Add-Drop Multiplexer configuration.
This is provided through the 10/100 Mbps NMS (Ethernet)
port or an RS232C craft port.
External 2Mbps or 2.048 MHz timing signal inputs are
provided for synchronizing the equipment.
This is provided through the analog 2-wire interface. The
EOW bytes are software selectable to E1 or E2.
These provide dry contacts for extending the alarms. Five
such potential free outputs are provided that are tied to alarms for
Critical, Major, Minor, Order Wire and Power. Two potential free
inputs are provided for environmental alarms like "Power or
Air-conditioning failure", " equipment room door open" etc.
A 2.048 M BITS clock output is
available from the system, which can be set to either a 2.048 MHz
clock or a framed E1 data at 2.048 Mbps.
