Conclusion
The use of the G.704 framing protocol is simpler, more reliable and more
flexible. A higher bandwidth can be achieved with an unstructured G.703
connection. In the event of especially favorable line conditions (short
distances, few intermediate switching stations, only one remote station), the
additional protocol overhead of a G.704 connection may not be worthwhile.
5.2.5 Setting up the basic protocols
As complex as the world of 2-Mbit standards may be, the configuration of
your
ELSA LANCOM Business is still a simple matter.
To set up Internet access or interconnect two networks using a 2-Mbit
connection, launch the appropriate wizard using
LANconfig or WEBconfig .
X.21 interface
No further input is necessary when using an X.21 interface and a terminal
adapter. In this case the configuration of all connection parameters is
performed at the terminal adapter, assuming that these are not already fixed.
G.703 interface
If you choose a G.703 interface for the connection, you will be asked which
basic protocols should be used.
Three options are available:
E1-U – unstructured E1
E1-S (with TS16) – structured E1, only TS0 reserved
E1-S – structured E1, TS0 and TS16 reserved
The choice of E1-U or E1-S (with TS16) depends on how your provider has
configured the line—whether it has been set to unstructured G.703, or
whether it also uses G.704 framing.
E1-S should only be selected if the
remote device requires the reservation of TS16 for control data. This is the
case with some terminal adapters.
Changing the settings manually
You can change the interface settings manually at any time. You can find the
menu under:
