Passport 8250
This section describes the Passport 8250 device. Youcan view the following
topics in this section:
•“Passport 8250 functions” (page 15)

Passport 8250 functions
The Passport 8250 is an Integrated Access MUX, a rugged,high-densityunit
that provides a seamless bridge between traditional voice networks and ATM
networks. The Passport 8250 multiplexes TDM traffic - voice, video, IP,
frame relay, X.25, and SNA - on DS-1/E1 trunks to OC-3c/STM-1 fiber
trunks (ATM over SONET/SDH). Using ATM Forum AAL1 circuit
emulationstandards,traditionalvoice networktraffic(dial-up Internet access,
modem data traffic, telephony, and more) is seamlessly transported over the
efficient, high-bandwidth ATM network. Deployed at either the service
provider setting or customer premises (campus,apartment building, or office
center, for example), the high-density unit supports up to 48 DS-1/E1 ports,
up to 336 DS-1s/E1s in a single frame.

Network board
The networkboardisasingle-mode or multi-mode integrated dual trunk. The
network board controls the Passport 8250 device and contains the
communication ports.
DS-1 and E1 service boards
The Passport 8250 device can hold one, two, or three DS-1 or E1 service
boards.Serviceboards send andreceive DS-1/E1signalsand convertbetween
ATM cells and DS-1/E1 traffic. Each service boardhas 16 physical DS-1/E1
ports.

Communication ports
The communication ports, which are locatedonthe network board, include a
serial port, ethernet port, and redundant ATM uplink port.
Serial port
The serial port connects the Passport 8250 device to a local host using a
RS-232 cable. Using a standard terminal emulation software application
running on the local host, you can directly access thecommandlineinterface
(CLI).
Use theserialportto configure the Passport8250device for operations before
the Passport 8250 device is connected to your network.
Ethernet port
The ethernet port connects the Passport 8250 device to a local area network
(LAN) using a RJ-45 cable.You can use a Telnet session on a remote host to
remotely access the CLI, provided the Passport 8250 device already has an
Internet protocol (IP) address.
Use theethernetportto configure the Passport8250devicewhile the Passport
8250 device is connected to your network and to communicate with other
devices within your network.
Dual power supply modules
Fan module
241-5101-200 R2.2
Redundant ATM uplink port
The ATM uplink port connects the Passport 8250 device to the ATM network
using a STM-1/OC-3 single-mode or multi-mode fiber optic cable. The ATM
uplink port has two physical connectors and one connector is configured as
the primary port that listens for incoming signals from the ATM network.
The Passport 8250 device uses two field-replaceable 10 amps, -10 V DC
power supply modules. Each power supply module has a 3w3-D connector
and independent power feed.
If a power supply module fails, the Passport 8250 device can operate
temporarilyusingonepower supplymoduleand one powersupplyfiller pack.
A field-replaceable fan module cools the internal components of the Passport
8250 device.
Passport 8250 software
You do not have to order software for the Passport 8250. The Passport 8250
comes preloaded with the operating system and the applications it needs.
Base trunking software is included with the integrated trunk/control card
(network board), and the CES software with the access modules (service
boards), so no service support is required.
You can use the Network Management System (NMS) software to manage
the Passport 8250 devices. For information on installing and configuring the
NMS software, see NTP
.
