Functional Description

Front Panel Connectors

Management LAN Ports

Two triple-speed (10M/100M/1000M) management LAN RJ-45 connectors are provided for use as
out-of-band management ports. The speed of the management LAN is autonegotiated.

Console Port

The EIA/TIA-232 RJ-45 Console Port provides a data circuit-terminating equipment (DCE) interface for
connecting a console terminal. This port defaults to 9600 Baud, 8 data, no parity, 1 stop bit with software
handshake.

Auxiliary Port

The EIA/TIA-232 RJ-45 Auxiliary port provides a data circuit-terminating equipment (DCE) interface
that supports flow control. Use this port to connect a modem, a channel service unit (CSU), or other
optional equipment for Telnet management. This port defaults to 9600 Baud, 8 data, no parity, 1 stop bit
with software handshake.

Alarm Out

Alarm circuitry on the RSP activates dry contact closures that are accessible through the nine-pin Alarm
Out connector on the RSP front panel. Each RSP card drives a set of three alarm output contacts. Both
normally-open and normally-closed contacts are available.
Only the active RSP drives the alarm outputs. Should a switchover to the standby RSP occur, the newly
active RSP drives the alarm outputs.

Synchronization Ports

The SYNC ports are not currently supported. They are provided for future release functionality.
Note
The SYNC 0 and SYNC 1 ports are timing ports that can be configured as Building Integrated Timing
System (BITS) ports. A BITS port provides a connection for an external synchronization source to
establish precise frequency control at multiple network nodes, if required for your application. The RSP
card contains a Synchronous Equipment Timing Source (SETS) that can receive a frequency reference
from an external BITS timing interface or from a clock signal recovered from any incoming interface,
such as a Gigabit Ethernet or 10Gigabit Ethernet interface. The RSP 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 UTI ports. A Universal Timing Interface (UTI) port
is used to connect to an external UTI 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.
