Dial Shelf Controller Card
Dial Shelf Controller Card
The dial shelf controller card is the main processor card for the dial shelf, and it performs the
following functions:
• Links the dial shelf to the router shelf, where data is transferred as Ethernet packets encapsulated
in proprietary protocol
• Interconnects trunk cards and modem cards
A backplane interconnect concentrator on each dial shelf controller card connects to each dial
shelf card installed in the dial shelf.
• Boots and reloads software images
• Provides source clocks used by all dial shelf cards and power supplies
• Extracts an external reference clock from an external E1 or T1 signal through a BNC connector
on the front panel
• Connects to an external alarm source through a DB-15 serial connector located on the front panel
Install the dial shelf controller card in the Cisco 5814 dial shelf in either of the two far-right slots
(numbered 12 and 13). The card plugs directly into the backplane.
The dial shelf controller card consists of the following components:
• CPU (IDT R4700)
• 150-MHz microprocessor
• I/O controller
• Onboard Flash memory
• PCMCIA Flash memory
• Boot Flash memory
• EPROM
For detailed specification tables, refer to Appendix A, “Cisco AS5800 Specifications.”
