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
