FEATURES AND SERVICES
Administration Requirements
System (Pooled Modems):
● Modem Request Code (1-9999; default = 820). Allows users to indicate a need for a
conversion resource on a data call originated at an analog data endpoint.
● Receiver Responds To Remote Loop (yes or no; default = yes). When active, Data
Set Ready is asserted when the modem is in an analog loop test mode.
● Disconnect On Loss Of Carrier (yes or no; default = yes). When active, a loss of the
received carrier will cause the modem to terminate the call.
● CF-CB Common (yes or no; default = yes). When active, Clear to Send turns off if
Carrier Detect turns off. When a call is being established, Clear to Send and Carrier
Detect are not allowed to turn on until carrier has been received and the Clear to
Send timer has timed out.
● Disconnect On Received Space (yes or no; default = yes). When active, the modem
will disconnect after receiving a “Space” signal of approximately two seconds
duration.
● Send Space On Disconnect (yes or no; default = yes). When active, the modem,
upon receiving a negation of Data Terminal Ready, sends approximately four
seconds of “Space”
signal and then disconnects.
Without this option active, the
modem, upon receiving a negation of the Data Terminal Ready signal, disconnects
immediately.
Hardware Requirements
One TN758 Pooled Modem CP provides two conversion resources. Two TN758s are allowed
