Introduction

Central Site Model
The central site Excalibur Multirate DAP consists of a printed circuit (p.c.) card and a
transition board (vertical rear panel) that are designed to be housed in the high-density
Excalibur Card Carrier (Figure 1-2). Each card carrier can house up to 16 p.c. cards. Six
card carriers, holding up to 96 single port Excalibur Multirate central site DAPs, can be
installed in a single 6-foot rack. The card carrier contains a Master Control Panel that
can control any of the 96 DAPs in the rack. For more information on the Excalibur Card
Carrier, refer to that product's instruction manual.
Note: The Aggregate card requires a single slot if the DAP has no IDBU or if it is
equipped with Switched 56 or ISDN IDBU. If the DAP is equipped with Analog IDBU,
the Aggregate card requires two card slots since the front portion of the card slot
immediately to the left of this card as viewed from the front of the card carrier must be
vacant.
