CTP card

The Director 2/140 ships with two Control Processor (CTP) cards. The active CTP card initializes
and configures the director after power on, and contains the microprocessor and associated logic
that coordinate director operation. The second CTP card serves as a backup. A CTP 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 CTP card without switching off power or
affecting operational fiber-optic links.
Each CTP 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 CTP 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,
CTP cards provide non-volatile memory for storing firmware director configuration information,
persistent operating parameters, and memory dump files. Director firmware is upgraded
concurrently (without disrupting operation).
