CTP2 card

The Director 2/64 ships with two Control Processor (CTP2) cards. The active CTP2 card initializes

and configures the director after power on, and contains the microprocessor and associated logic

that coordinate director operation. The second CTP2 card serves as a backup. A CTP2 card

provides an Initial Machine Load (IML) button on the faceplate. When the button is pressed and

held for three seconds, the director reloads firmware and resets the CTP2 card without switching off

power or affecting operational fiber-optic links.

Each CTP2 card also provides a 10/100 megabit per second (Mbps) RJ-45 twisted pair connector

on the faceplate that attaches to an Ethernet Local Area Network (LAN).

Each CTP2 card provides System Services Processor (SSP) and Embedded Port (EP) subsystems. The

SSP subsystem runs director applications, communicates with director ports, and controls the RS-232

maintenance port and 10/100 Mbps ethernet port. The EP subsystem provides Class F processing,

and manages frame transmission to and from the Serial Crossbar Assembly (SBAR). In addition,

CTP2 cards provide non-volatile memory for storing firmware director configuration information,
