OW (LAA14) Circuit Pack Description 7
Purpose of Circuit 7
The Orderwire (OW) circuit pack provides access to the OC-48 SONET section
overhead channel. The overhead channel contains the SONET section overhead
bytes.
One LAA14 OW circuit pack is optional for the FT-2000 OC-48 Repeater Bay.
However, the LAA14 OW circuit pack is required for orderwire access at repeater
sites. The LAA14 OW circuit pack is compatible with Release 2.1.0-RPTR and
later software.
Faceplate 7
Figure 7-11 shows the OW circuit pack faceplate. The faceplate of the OW circuit
pack does not have a red FAULT LED.
