Watson Ethernet
Operating Manual
The entire chain can be managed from a centralized site through inband man-
agement.
The Watson Ethernet tabletop modems can also be used together with Watson
TDM modems with E1 or nx64 user interfaces to transport Ethernet packets over
Wide Area Networks:
Figure 2-4: Ethernet over WAN
Here Watson Ethernet tabletop modems are installed at the customer premises
and Watson TDM modems in the central office. Ethernet packets are transported
transparently from one Watson Ethernet modem to the other. No intermediate
protocol conversion (e.g. ATM) is required to map Ethernet to the E1/SDH or
Frame Relay WAN. Instead of establishing a connection between two Watson
Ethernet tabletop modems the connection can also be terminated in the WAN
port of a router supporting the Cisco HDLC protocol.
