Chapter 2 Functional Description
Route Processor Card
interface, such as a Gigabit Ethernet, 10-Gigabit Ethernet, or SONET interface. The RSP/RP SETS
circuit filters the received timing signal and uses it to drive an outgoing Ethernet interface or BITS output
port.
The timing port(s) can also be configured as J.211 or DTI ports. A DOCSIS Timing Interface (DTI) port is
used to connect to an external DTI server to synchronize timing and frequency across multiple routers.
The timing function allows precise synchronization of real-time clocks in a network for measurements
of network performance, for example, measuring delay across a VPN. The frequency reference acts like a
BITS input.
RP USB Port
The RP card has a single external Universal Serial Bus (USB) port. A USB flash memory device can be
inserted to load and transfer software images and files. This memory device can be used to turboboot the
system or as the installation source for Package Information Envelopes (PIE) and Software Maintenance
Upgrades (SMU). This memory device can also be used for users' data files, core files, and configuration
backups.
Front Panel Indicators
The RSP card has eight discrete LED indicators and an LED dot-matrix display for system information.
The RSP-440 adds three USB-specific LEDs. The RP has nine discrete LED indicators and an LED
dot-matrix display for system information.
Table 2-1 shows the display definitions of the eight discrete LEDs on the RSP front panel and the three
RSP-440 specific USB LEDs.

Network (CAN) bus controller after it is up and running.
Off Standby power is normal.
Critical Alarm
(CRIT)
Red Critical Alarm LED. A critical alarm has occurred.
Off 
(Default after reset)
No critical alarm has occurred.
Major Alarm
(MAJ)
Red Major alarm LED. A major alarm has occurred.
Off 
(Default after reset)
No major alarm has occurred.
Minor Alarm
(MIN)
Amber Minor alarm LED. A minor alarm has occurred.
Off 
(Default after reset)
No minor alarm has occurred.
Synchronization
(SYNC)
Green System timing is synchronized to an external timing source.
Amber System timing is free running.
Off LED never turns off.
