Passport 8250
This section describes the Passport 8250 device. You can view the following
topics in this section:
• “Passport 8250 functions” (page 15)
• “Passport 8250 hardware” (page 16)
• “Passport 8250 software” (page 19)
• “Related documents” (page 19)
Passport 8250 functions
The Passport 8250 is an Integrated Access MUX, a rugged, high-density unit
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,traditional voicenetwork traffic(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.
See “Passport 8250 device” (page 16) for an illustration of the Passport 8250.

Passport 8250 device
The Passport 8250 can be used for the following applications:
• Providing medium to high density DS-1 or E1 ingress to an ATM carrier
network.
• Providing medium to high density DS-1 or E1 ingress to an ATM
wireless network.
• Acting as a traffic bridge between ATM network and TDM Trunks.
Passport 8250 hardware
The Passport 8250 device contains the following hardware components:
• Base chassis
• “Board modules” (page 17)
• “Communication ports” (page 18)
• “Dual power supply modules” (page 18)
• “Fan module” (page 18)

Board modules
The Passport 8250 device has a field-replaceable network board and up to
three field-replaceable DS-1/E1 service boards.
Network board
The network board is a single-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.Service boards send and receiveDS-1/E1signalsandconvertbetween
ATM cells and DS-1/E1 traffic. Each service board has 16 physical DS-1/E1
ports.

Communication ports
The communication ports, which are located on the 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 the command line interface
(CLI).
Use the serial port to configure the Passport 8250 device 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 the ethernet port to configure the Passport 8250 device while the Passport
8250 device is connected to your network and to communicate with other
devices within your network.
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.
Dual power supply modules
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
temporarilyusingonepowersupply module and one powersupply filler pack.
Fan module
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 241-6001-110, NMS Passport 8250 Integration
Guide
