Management LAN Interfaces
SPIO management LAN interfaces connect the system to the carrier's management network and applications,
normally located remotely in a Network Operations Center (NOC). You can use the RJ-45 copper 10/100/1000
Mbps Ethernet interfaces or optical SFP Gigabit Ethernet interfaces to connect to the management network.
When using the RJ-45 interfaces, use CAT5 shielded twisted pair (STP) cabling.
Use shielded cabling whenever possible to further protect the chassis and its installed components from
ESD or other transient voltage damage. Important

Console Port
The console uses an RS-232 serial communications port to provide local management access to the command
line interface (CLI). A 9-pin-to-RJ-45 console cable is supplied with each SPIO card. The console cable must
provide carrier-detect when attached in a null modem configuration.
Should connection to a terminal server or other device requiring a 25-pin D-subminiature connector be required,
a specialized cable can be constructed to support DB-25 to RJ-45 connectivity. The baud rate for this interface
is configurable between 9600 bps and 115,200 bps (default is 9600 bps).
BITS Timing
The Building Integrated Timing Supply (BITS) timing interface is optional and required only when the system
is used in support of non-data applications. A BITS module is available on two versions of the SPIO: one
supports an analog E1 BNC coaxial interface (for 2048 kHZ clocking), and the other a T1 (DS1) 3-pin
wire-wrap interface (for 1544 kHz clocking).
If your system is equipped with OLC2 or CLC2 line cards for SDH/SONET, you can configure it to derive
system clocking from a port on either card. This functionality requires that the SPIO includes the optional
Stratum 3 clocking module to distribute clocking to all line cards in the chassis.
