SF/CPM PORT TYPES
Figure 56 displays the port types on the SF/CPM.
Figure 56: Port Types
• The Building Integrated Timing Supply (BITS) port on the SF/CPM front panel is a clock
in a central office that supplies digital signal level 1 (DS1) and/or composite clock timing
references to all synchronous network elements in that office. This port is provisioned
with an RJ-48 connector. An appropriate T1 cable must be used to connect an
asynchronous serial device to this port.
• The Console port is a Universal Asynchronous Receiver/Transmitter (UART) port used to
configure router and system parameters and can be also be used for monitoring purposes.
The console port is enabled by default. The default Baud rate is 115,200. This port is
provisioned with an DB-9 connector. Connect the console port to a terminal with an RS-
232 serial cable.
The DTE/DCE switch on the front panel controls the serial port type as either data
terminal equipment (DTE) or data communications equipment (DCE).
Flip the switch to DTE when connecting to the serial port of a PC with a null modem
cable. Flip the switch to DCE when connecting to the serial port of a PC with a straight-
through cable.
The port is configured as DTE or DCE depending on the switch setting. No crossover
cables are required.
• The Auxiliary port is a Universal Asynchronous Receiver/Transmitter (UART) port used
to connect a modem, laptop, or other auxiliary devices to the router. It is configured as data
terminal equipment (DTE). This port is provisioned with an DB-9 connector. You must
use an RS-232 serial cable to connect an asynchronous serial device to this port.
• The Alarm port is provisioned as a DB-9 serial port and is used to connect to external
alarm devices that report conditions that trigger red or amber alarms. You must provide an
appropriate cable configured according to the your alarm panel.
• The Management port is a 10/100 Ethernet port which is a channel to download images
and manage the system. This port is provisioned with an RJ-45 jack on the front panel.
You must provide a CAT5 Ethernet cable to connect to the port.
