OPTI-3 Controller Module (OCM) provides an OC-3 interface to the network and three ADD/DROP DS3

interfaces to the Loop.  The OCM can be configured for a point-to-point configuration or subtended from 3rd party SONET
equipment.  The OCM operates in terminal mode only.  The compact design mounts in either a rackmount or wallmount
chassis, requiring less space and provides optional redundancy.  It can automatically switch to the offline unit in the event of
optical signal failure or degradation.  The modules are fully hot-swappable. 

Compliant with SONET standards, the OCM functions as a terminal multiplexer.  It supports 1+1 OC-3 equipment and facility
protection, 1:1 OC-3 equipment protection (system provisioned for optical Ycable), 1:1 DS3 facility protection, and detects
standard optical related alarm conditions.  The OCM can be configured to operate redundantly with optional protection of
the optics components.  It can be upgraded online from un-protected to protected and operating software can be upgraded
remotely in Back-to-Back configurations.

The OCM is easily managed with TL1 commands over the Data Communications Channel (DCC) or via Command Line
Interface (CLI) through the local craft interface.  Additional features include remote alarm transport via DCC and alarm
reporting to legacy alarm systems.

This job aid relates to OPTI-3 System Release 1.3 (Dseries).  The menus and functionality are an extension of the prior system
release (OPTI-3 System Release 1.2 - Cseries).  The latest software is not compatible with System Release 1.1 (Bseries).

The Total Access OPTI-3 can be installed in either a Rackmount Chassis (RMC), P/N 1184003L1, or a Wallmount Chassis
(WMC), P/N 1184001L1.  The RMC provides two OCM slots, side by side, with slot A on the left and slot B on the right.  (See
Figure below.)  The WMC provides two OCM slots, positioned vertically with slot A below slot B.  Ensure the appropriate 
chassis is installed before proceeding with the OCM installation. 

Carefully insert the OCM halfway into the selected slot.  Route the fiber cables through the notch on the OCM front panel and
approximately 4 inches past the SC receptacles (to create slack).  Gently but firmly push the OCM all the way into the slot,
being careful not to pinch the fibers between the front panel and the shelf.  Push the latch/ejector tab toward the front panel
to lock it into place.

When the OCM 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. 

If installing a redundant system, repeat the preceding procedure for slot B.  If not installing a second OCM, a blank faceplate
(P/N 1184005L1) must cover the empty slot.

■

When depressed simultaneously with the TEST/ENABLE switch on the Offline unit, a switch is forced
between the two OCMs.

■

When depressed with the TEST/ENABLE switch on the Online unit, it toggles LOCKOUT status.

■

When depressed alone, tests all unit LEDs (multicolor LEDs appear YELLOW).

■

When depressed simultaneously with the APS switch on the Offline unit, a switch is forced between
the two OCMs.

■

When depressed after an audible alarm is sounded, silences the alarm.

■

When depressed after any other alarm is triggered, acknowledges alarm.

■

Provides menu access via RS-232 (Craft) port on the front panel.

■

Connects to VT100 compatible terminal using a DB-9 serial cable.

■

Requires setting VT100 terminal emulation (to 9600, 19200, 38400, 57600, or 115200 bps), 8 Data Bits,
No Parity, 1 Stop Bit, and No Flow Control.  (The baud rate default is 9600 bps, which can be 
modified through the VT100 menu system.

■

Provides access to both OCMs installed in the chassis with connection to either OCM craft port.
