1. General Function
The PA-SDTA circuit card provides a maximum of 28 interface (1.5 Mbps) used with the fiber optic cable.
This card has also the MUX function and is connected directly to the TSW card. This card is used with the
PA-SDTB card.

2. Mounting Location/Condition
This circuit card is mounted in a universal slot next to (either left or right side of) PA-SDTB. When this
card is provided in a dual configuration, mount this card on both sides of PA-SDTB.
Mounting conditions are shown below.
Only the power is supplied from Back Wiring Board (BWB).
This card is connected to the PA-SDTB card using the following front cables.
For single configuration: SDT CABLEB 
For dual configuration: SDT CABLEA 
Fiber optic cables are connected to this card.
Time slots used for this circuit card are determined by the cable connection between the PA-SDTB and
TSW.
