TANDBERG D50104-15 user manual Call control, Network clocking

Advanced Use Health Care System III

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 only two codecs are connected in a point to point connection. Use ‘Leased Line’ when handshake signals DTR and CD are available. DTR and CD correspond to the X21 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.

TIP

TO MAKE AN IP CALL WHEN ‘LEASED LINE’ IS SELECTED, ENTER A NUMBER BEFORE PRESSING CONNECT TO ACTIVATE THE

DIAL MENU.

Network clocking

The network clock setting specifies the number of physical external clock signals.

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 the cable only.

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