External network settings
Before using the system together with external network equipment, you must specify the network
parameters on this page.
Call control
‘RS366 Dialing’
is the only dialing protocol and would normally be used together with network
clocking
‘RS449/V35 Compatible’
when the external equipment uses RS366 ports.
‘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.
‘Data Triggered’
mode uses TxData (transmit data), RxData (receive data) and clock signals only.
Use
‘Data Triggered’
when no handshake signals are available.
‘Manual’
should be used when no handshake signals are available, and the external equipment
requires a constantly connected line.
