Chapter 1
Introducing the Passport 8250
This section describes the Passport 8250. You can view the following topics
in this section:
• “Passport 8250” (page 15)
• “Main features” (page 17)
Passport 8250
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,traditionalvoicenetwork 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.

Typical applications
Typical applications for the Passport 8250 include the following:
• providing medium to high density DS-11/E1 ingress to an ATM carrier
network
• providing medium to high density DS-1/E1 ingress to an ATM wireless
network
• acting as a traffic bridge between ATM and Time Division Multiplexing
(TDM) networks
Benefits
The benefits of using the Passport 8250 include the following:
• protects existing equipment investments while migrating to ATM
• enhances network survivability and improves network reliability
• optimizes network utilization
• accommodates voice and data at high speeds and large volumes
• allows different services to be multiplexed on a common interface

Circuit emulation services (CES)
The Passport 8250 complies to ATM Forum CES-IS version 2.0 and supports
ATM adaptation layer (AAL1) constant bit rate (CBR) service for DS-1 and
E1 traffic.
The Passport 8250 supports unstructured and structured permanent virtual
circuit (PVC) connections. The structured connections consist of Basic and
CAS connections. For DS-1, the frames can be set to super frame (SF) or
extended super frame (ESF).

MIB browser
You can use a third-party MIB browser to view the MIB objects.
Reference clock configuration
The clocking scheme can be derived from the Passport 8250 device or from
the ATM network off an external port on the Passport 8250 device. When the
clock is derived from an external port, you can switch from the primary port
to the secondary port. For details on the clock configuration, see NTP 241-
5101-200, Passport 8250 Installation Guide.
Constant bit rate (CBR) clocking
For structured services, Passport 8250 supports synchronous CBR clocking.
For unstructured services, Passport 8250 supports synchronous and
synchronous residual time stamp (SRTS) CBR clocking. Different ports on a
single service board can use different clocking modes.
Fault management
The Network Management System (NMS) is the carrier domain management
system and it provides integrated fault management of Passport switches and
Passport 8250 multiplexers. For details on the NMS Advisor tools, See NTP
241-6001-011, NMS Advisor User Guide.
Flash file system
The Passport 8250 stores system software and configuration data in flash
memory. You can view the directory structure in the CLI and download new
system software through a network connection using FTP. For details on flash
memory, see “Flash file system” (page 65).
