PACKET MANAGER > PACKET ENDPNTS > CONFIG > SUBLINKS - FRAME RELAY
Write security: 3; Read security: 5
Contains the configuration parameters for individual sublinks, or PVCs. The following parameters are
available.
SLOW POLL RATIO
Write security: 3; Read security: 5
Configures the ATLAS 550 to send polls to unresponsive remote units at a slower rate than normal.
The number entered sets the ration. When a remote unit is polled repeatedly and no answer is
received, the ATLAS 550 will move the unit from the normal poll interval to the slow poll interval. If
5 is entered here, the remote units on the slow poll will only get polled after the responsive units have
been polled 5 times.
DISCONNECT THRESHOLD
Write security: 3; Read security: 5
Sets the threshold for considering a remote unit inactive. This is determined using unanswered status
polls.
TRANSMIT DELAY
Write security: 3; Read security: 5
Configures the ATLAS 550 to introduce a delay between packets transmitted on this endpoint (in
seconds). The ATLAS 550 will transmit a packet (any traffic - data, poll, etc.) then wait the entered
seconds before transmitting another packet.
CTS OPTION
Write security: 3; Read security: 5
Configures the Clear To Send (CTS) signal on this interface. CTS may be forced on or can be
configured to be asserted only when Request To Send (RTS) is asserted.
DATA FORMAT
Write security: 3; Read security: 5
Configures the data format scheme used on this SLDC endpoint for either NRZ (Non-Return to
Zero) or NRZI (Non-Return to Zero Inverted). Using NRZ configures the Legacy Data Module to
encode using ones and zeroes represented by opposite and alternating high and low voltages. There is
no return to a zero reference voltage between encoded bits. Using NRZI configures the Legacy Data
Module to encode ones with a voltage change and zeroes with no voltage change. NRZI encoding is
also known as transition coding
NAME
Write security: 3; Read security: 5
User-definable name for the DLCI.
