WAN Ordering Information
If your Nautica 4000 has a WAN port, connection to a remote unit
can be made via a permanent leased circuit.
European WAN Information
• Most European public network digital leased circuit services
are provided with an X.21/V.11 Network Terminating Unit
(NTU) by the service supplier. This can be directly connected
to the Nautica 4000 with the WAN cable provided.
• If the leased circuit is supplied without an NTU, one must be
provided before connection to the Nautica 4000.
• The WAN interface on the Nautica 4000 can be supplied as
standard with X.21/V.11, V.35/V.10, or V.24/V.28 using the
relevant CLAM WAN Module (C-WAN).
• Ensure that your Nautica 4000 is fitted with the correct
interface for the terminating unit supplied.
North American WAN Information
• Leased circuit services in North America are not normally
provided with line terminating equipment. A Channel
Service Unit/Data Service Unit (CSU/DSU) must be
obtained to connect the line and the Nautica 4000.
• Ensure that your Nautica 4000 is fitted with the correct
interface for the terminating unit supplied (V.35/V.10 is
standard).
