Remote Access
High-Speed Links
Connecting FDDI, Fast Ethernet
backbones, and ATM (via an MP
ATMLink OC-3c module or HSSI
WAN module), links to NETBuilder II
routers provide fast access to
high-speed network resources.
Central Routing
Configuration
For advanced levels of
network control and
security, a NETBuilder II
router provides logical
segmentation for each
LAN hub in a building.
ATM Connections
The MP ATMLink™ module provides
connectivity to ATM backbones with
multiprotocol encapsulation and
LAN Emulation.
Protect Your Network with Back-Up PC Cards
Central and regional site concentrations are important areas
of convergence on your network, so protect your network
by purchasing extra blank PC Cards for dual images and full
dump capabilities. You may also use the network manage-
ment station to contain backup configuration files of
different routes. You should also keep a few PC Cards with
boot images on hand for emergencies.
Dial Services
NETBuilder II router dial
services include cost-saving
dial-on-demand, dynamic
dial pooling, bandwidth-on-
demand, and scheduled
dial, plus the fault tolerance
of dial backup.
Wide Area Links
NETBuilder II routers offer
point-to-point wide area ser-
vices including leased line and
dial-up connections as well as
WAN services through cloud
technologies: X.25, Frame Relay,
SMDS, ATM DXI, and ISDN.
