CRAFT INTERFACE

■ 

Connect to terminal using a serial cable with a male DB-9 connector.

■ 

Set VT100 terminal emulation to 9600 bps, 8 Data Bits, No Parity, 1 Stop Bit,
and No Flow Control.

■ 

Baud rate is configurable at 9600, 19,200, 38,400 or 115,200 bps.

DESCRIPTION

The OPTI-T200 is designed to work in a back-to-back mode of operation,
OPTI-T200 to OPTI-T200.  It uses a standard 1310 nm OC3 signal to interface
between the systems and provides a single DS3 signal to the loop.  The 
OPTI-T200 provides DCC communication with TL1 support.  A craft port and
an Ethernet port are available on the front panel for management.  The 
OPTI-T200 is a T200 mechanics card, which will fit standard T200 and T400
enclosures.

Compliant with SONET standards, the OPTI-T200 functions as a terminal 
multiplexer, detecting standard optical, SONET, and DS3 related alarms and
conditions.  The OPTI-T200 is easily managed with TL1 or TCP/IP commands,
or Telnet sessions separately to each system or via the craft interface.

For a complete Installation and Maintenance Practice (P/N 61184400L1-5): 877-457-5007, Faxback Document 918.  Please have your fax number ready.  

INSTALLATION

The OPTI-T200 is a T200 mechanics card which will fit standard T200 and T400 enclosures.
Ensure the appropriate chassis is installed before proceeding with the installation. 

Carefully insert the OPTI-T200 halfway into the selected slot.  Route the fiber cables to the
front panel and approximately 4 inches past the SC receptacles (to create slack).  Gently but
firmly push the OPTI-T200 all the way into the slot, being careful not to pinch the fibers
between the front panel and the shelf. 

WARNING

: Once fully inserted into the chassis, the module will be powered (provided power

is connected to the chassis).

When the OPTI-T200 powers up, it performs a self-test.  The front panel LEDs illuminate for
approximately 8 seconds.  The self-test is complete once the STATUS LED illuminates
Green.
