External Connections
• Modem carrier card with MICA
The Cisco AS5200 access server can contain up to 60 modem ports installed on two carrier cards
in the chassis card slots. Each modem carrier card holds up to five, 6-port MICA modem
modules. The modem cards connect through the carrier card and the system backplane to the dual
T1 PRI card. Transmission or reception is then accomplished on T1 lines connected to the dual
T1 PRI card.
A serial connection to the modem can be made through the Ethernet attachment unit interface
(AUI) port or the serial ports on the chassis.
A blank slot cover is installed over any unused slots.
Other External Connections
Additional external connections for the Cisco AS5200 are as follows:
• Two serial WAN interface ports
The serial ports on the Cisco AS5200 are five-in-one synchronous serial using 60-pin, D-type
connectors. The interface supports EIA/TIA-232, EIA/TIA-449, V.35, X.21 (NRZ/NRZI and
data terminal equipment (DTE)/DCE mode), and EIA-530 (NRZ/NRZI and DTE mode).
• One Ethernet LAN port using an AUI, DB-15 connector
• Console port
An EIA/TIA-232 (RJ-45) console asynchronous serial port connects to a terminal using an RJ-45
cable and an RJ-45-to-DB-25 adapter or to a PC using an RJ-45 to DB-9 adapter.
• Auxiliary port
An EIA/TIA-232 (RJ-45) auxiliary asynchronous serial port can connect to a modem for remote
maintenance or other access services. The port uses an RJ-45 roll-over cable with a male modem
(MMOD) adapter (labeled “Modem”) for this connection.
• Alarm port connections
The three-pin alarm port is a future enhancement that will connect the Cisco AS5200 to an
external audio, visual, or other alarm. The alarm port is not supported by current versions of the
system software or the feature cards.
• Two Cisco AS5200 power supplies provide AC or DC power input and supply DC power to the
installed cards via connectors in the backplane. Either the AC or DC power supply is required in
the chassis.
