Configuration Overview
The DAG 7.1S card uses four integrated SONET/SDH ATM/PoS physical
layer interface devices to support capturing of ATM cells or HDLC
encoded Packet-over-SONET data frames.
The card supports unchannelized POS/ATM; OC-3c, OC-12c, STM-1c and
STM-4c standards for transmit and receive. Additionally channelized
ATM/HDLC receive is supported on a single port only.
Because of its flexibility, the correct link layer configuration needs to be
supplied to the card for it to function as expected.
A successful DAG card capture session is accomplished by checking the
receiver ports optical signal levels and checking the card is locked to
stream data. This is followed by configuring the DAG card for normal
use. These steps are described next.
Check Receiver Ports Optical Signal Levels
The card supports 1300 nanometreer singlemode and multimode fibre
attachments with optical signal strength between 0 dBm and -22 dBm.
If there is doubt, check card receiver ports light levels are correct using an
optical power meter.
The card receiver ports are the lower of each dual-LC-style connectors, the
closest to the PCI-Express slot.
Cover card transmit ports with LC-style plugs to prevent dust and
mechanical hazards damaging optics if not in use.
