T1-EtherRocket and Remote Router Porting
Patton Electronics introduces a new way of interconnecting remote branches
to a Main Office LAN using the T1-EtherRocket. Called ?Remote Router
Porting? (RRP), it offers network managers and integrators a simple and
economical way for LAN-to-LAN deployments.
At the branch office, RRP replaces the traditional router and CSU/DSU
solution with Patton?s EtherRocket Access Unit, which includes integrated
T1 and 10Base-T transparent bridging. This unit allows for high-speed PPP
data connections across the Wide Area Network at scalable data rates of
nx56/nx64kbps up to 1.544Mbps, and also connects directly to the 10Base-T
branch office LAN at 10Mbps. The T1-EtherRocket transparently forwards
Ethernet packets to a headquarters LAN based on their destination MAC
address.
At headquarters, RRP builds on the bridging capabilities of a router to
extend their serial or WAN ports across town or across the country. In
order for the central routed network to connect to a remote branch
Ethernet network, the serial or WAN interface of the router needs to be
configured as a PPP IP half-bridge. In this configuration the
T1-EtherRocket sends bridge packets (BPDUs) to the router?s WAN interface.
The router will then look at the layer-3 address information and will
forward these packets based on its IP address. The router?s port,
connected through the T1 network and T1-EtherRocket, appears as a virtual
Ethernet interface at the branch office network.
The Model 2720/I T1-EtherRocket supports D4/ESF framing options and
AMI/B8ZS/B7ZS line coding. Data rates, framing, and coding options are
programmed by DIP switches or from a VT-100 terminal with menu-driven
software. A full range of system and diagnostic features make setup simple
and easy.
