4.8.1.4 External Network Settings
Before using the system together with external network equipment, you must specify the
network parameters on this page. The system has support for up to 2 Mbps using the
External Network (RS449/V.35/X.21) interface. Note that the physical interface on External
Networks is one non-standard 26 pin connector. Special cables are required.
Call Control
RS366
Dialing
RS366 Dialing is the only dialing protocol supported and would normally be
used together with network clocking RS449/V.35 Compatible when the
external equipment uses RS366 ports.
Leased
Line
Leased Line is a non-dialing protocol and should be used when two codecs
are connected in a point-to-point connection. Use Leased Line when the
handshaking signals DTR and CD are available. DTR and CD correspond to
the X.21 network
’
s C and I signals.
Manual
Manual should be used when no handshake signals are available and the
external equipment requires a constantly connected line.
Network clocking
The network clock setting specifies the number of physical external clock signals.
RS449/V35
Compatible
Use RS449/V35 Compatible when the external equipment provides
two clock signals, one for transmit and one for receive. The
difference between RS449 and V35 is only the cable.

Compatible
Use X21 Compatible when the external equipment provides a
common clock signal for both transmit and receive.
