Here a Watson 5 Ethernet tabletop modems are installed at the customer premises and Watson 5
TDM modems in the central office. Ethernet packets are transported transparently from one Watson
5 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 5 Ethernet tabletop modems the connection can also be terminated in the WAN port of a
router supporting the Cisco HDLC protocol.
