The Passport 8683 PoS Routing Switch
module is a baseboard with three slots
to house MDAs. There are four MDAs
available for the PoS baseboards:
• 1-port OC-12c/STM-4 MDA
for SingleMode SONET media
• 1-port OC-12c/STM-4 MDA
for MultiMode SONET media
• 2-port OC-3/STM-1 for MDA
for SingleMode SONET media
• 2-port OC-3/STM-4 for MDA
for MultiMode SONET media
The baseboard supports up to six
OC-3/STM-1 lines or up to three
OC-12c/STM-4 lines. MDAs can be
"mixed and matched" for customers
wishing to deploy various speeds on
the same baseboard. The recommended
number of PoS baseboards is four per
Passport 8000 chassis. Out of band
management is provided via a RJ-45 port.
The Passport 8683 PoS Routing Switch
module provides a new level of reliability
in the LAN/MAN. Redundancy features
include Distributed Multi-Link Trunking
and hot swappable baseboards.The module's
SONET technology is ideal for aggregating
high volumes of traffic over fiber cable.
The Passport 8683 PoS Routing
Switch module can be easily managed
and configured with Nortel Networks
Device Manager, a graphical switch
configuration tool. Device Manager
simplifies the setup of the Passport 8000
Routing Switch series, the Passport 1000
Routing Switch series, the Nortel
Networks Business Policy Switch 2000,
the Nortel Networks BayStack* 350,
the BayStack 410, and the BayStack 450.

By incorporating Packet over SONET
router functionality, the Passport 8600
transparently extends high performance
switching from one campus to another
within a MAN. This eliminates the
need for an external SONET router that
would add cost, increase complexity and
decrease performance.
Customers with existing SONET rings
can connect the Passport 8683 PoS
Routing Switch module to existing Add
Drop Multiplexors (ADM). This provides
a maximum level of connectivity with
minimal disruption in the backbone
(see Figure 1).
The Passport 8683 PoS allows customers
with unused or dark fiber laid between
campuses to bypasses SONET multiplexors
and the costs associated with implementing
a new SONET ring (see Figure 1).
Many Internet Service Providers (ISPs)
are deploying routers at their point of
presence (POP). The Passport 8683 PoS
Routing Switch module allows customers
to lease an IP over PPP connection directly
from a service provider regardless of the
type of router being used (see Figure 1).
The Passport 8000 Routing Switch offers
a variety of LAN technologies including
10/100 Mbps and Gigabit Ethernet
connectivity. MAN technologies
include Packet over SONET, ATM
and extended Gigabit Ethernet.
The Passport 8000 is redundant at
multiple layers. Physical redundancy is
accomplished with N+1 redundant power
supplies, hot swappable modules and
dual fan trays. Trunk level redundancy
is accomplished with Distributed Multi-
Link Trunking. Routing redundancy
is accomplished with Virtual Routing
Redundancy Protocol (VRRP)
and Equal Cost Multi-Path Routing
(ECMP), available in a future release.
Nortel Networks Device Manager and
the command line interface commands
are shared across the entire Passport 8000
platform. Using common applications
and monitoring tools dramatically
decreases the network administration
cost associated with configuring
individual devices.
