Asynchronous/Synchronous

Operation

(Switch 5):

The Synch/Asynch

switch is used for modem operation. In the Synchronous mode, the Gateway

uses the transmitter signal element timing to

transmit

data. The

transmitter and receiver signal timing elements are both supplied by the

modem. In the Asynchronous position, the modem does not supply receiver

or transmitter timing elements and the Gateway uses internal clocks to

determine

receive

data sample points and to send

transmit

data. Y

ou should

select Asynchronous operation when you are using the Local Line.
