connectivity (for example SONET/SDH GNEs, digital
cross connect systems, DSLAMs, and so on) for alarm
monitoring, remote provisioning, and software
download. The Catalyst 2924M XL DC switch
provides a non-contending Ethernet interface for
SONET/SDH gateway network elements (GNEs) to the
Cisco 2610/2611/2621DC and Cisco 3662-DC-CO
DCN access routers. Features such as switched 10/100
Mbps bandwidth, Cisco Switch Clustering Technology
which allows the Catalyst 2924M XL DC to manage up
to 16 interconnected Catalyst 2924M XL DC and
1924DC switches, and optional fiber module to satisfy
ground isolation requirements between central office
floors make the Catalyst 2924M XL DC switch a
powerful DCN solution.

Points of Presence: The Catalyst 2924M XL DC can be
used by Internet Service Providers (ISPs) to inter-connect
components in POPs that are provisioned with DC
power. At distributed POPs, ISPs receive dial-up traffic
from the CO and pass it onto routers, which then
connect customers to the Internet. The Catalyst 2924M
XL DC can be used to aggregate traffic from Access
Servers to routers or to interconnect servers (for
example, DNS servers, Billing Processing Servers) and
other components (for example, Management agents,
Routers) in the POP. Features such as switched 10/100
Mbps bandwidth and optional fiber connectivity make
the Catalyst 2924M XL DC switch a powerful solution
for ISPs.
•
Wireless/Mobile Switching Centers: The Catalyst
2924M XL DC can be used by wireless companies to
connect and manage components in Mobile Switching
Centers (MSCs). Mobile Switching Centers aggregate
wireless voice traffic from multiple wireless base
stations. At each MSC, voice messaging, paging,
network management components are housed. The
Catalyst 2924M XL DC can be used to interconnect
these components and connect them to central
management applications. Features, such as switched
10/100 Mbps bandwidth, make the Catalyst 2924M XL
DC switch a powerful solution for wireless
communications companies.
Cisco Switch Clustering Technology
The Catalyst 2924M XL DC features Cisco Switch
Clustering technology. This breakthrough technology
enables up to 16 interconnected Catalyst 2900 XL,
3500 XL, and 1900 switches, regardless of physical
proximity, to form a single-IP managed network. Catalyst
2900 XL switches can be clustered using a broad range of
connectivity options to meet customer requirements,
including Fast Ethernet, Fast EtherChannel
®
technology,
Gigabit Ethernet, Gigabit EtherChannel technology and
the Cisco low-cost GigaStack GBIC. Because customers
are not limited by proprietary stacking modules and
stacking cables, Cisco Switch Clustering technology
expands the traditional stacking domain beyond a single
wiring closet and lets users “mix and match”
interconnections to meet specific management,
performance, and cost requirements.
Catalyst 2900 XL switches can be configured either as
command (with command software upgrade) or member
switches in a Cisco switch stack or cluster. The command
switch serves as the single IP address management point
and disburses all management instructions dictated by the
network administrator.
The Catalyst 2924M XL DC switch is an integral
component of the complete line of Cisco end-to-end LAN
solutions. Integrated Cisco IOS software provides
superior functionality for network management,
bandwidth aggregation, networked multimedia, and
virtual LAN (VLAN) support. The Catalyst 2924M XL
DC switch is upgradable via software, so your investment
is protected if your network grows or changes.
