10-6 Frame Relay Module 4.0 User Guide, Rev 01Maximum Bytes per Frameis the maximum frame size that will be transmitted on the port.Generate Clockspecifies whether the port will generate the clock necessary to synchronize traffic overthe link. If the port is a physical DCE (determined by the port's I/O cable interface),set this parameter to Y, since the physical DCE generates clock. If the port is DTE, setthe parameter to N.Rcv Clock (TT) from DTEallows the clock to be looped back from the DTE using the TT (Terminal Timing)signal, which can be helpful on high-speed lines. Generally, if the local interface isphysical DCE and the line speed is above 256 Kbps, this parameter should be set to Y.(Make sure the remote DTE is configured to provide the terminal timing.)Answer Non-Configuredwill (if Y) allow the HPAD to respond to all devices on the line. If N, the HPAD willrespond only to those devices that are configured on the node.Activate Connection w/o pollwill (if enabled) activate the TPAD connection without a poll of the connected device.Clear VC on Last Device Downif Y, causes the virtual circuit to be cleared when no terminals are using it.Multidropspecifies whether transmisison will be multidrop (several stations between end points)or point-to-point.Slow Poll Retry Countapplicable only to connections configured for multidrop, specifies how many timesthe control unit (CU) will be polled (if it is not responding) before it is put on the "slowpoll" list. CUs on the slow poll list will be polled with a frequency determined by theparameter Slow Poll Retry Frequency.Slow Poll Retry Frequencyspecifies the number of times active CUs will be polled between pollings of the CUson the slow poll list.# of Beginning Sync Charspecifies the number of synchronization characters that will be added to the beginningof each frame.# of Trailing Pad Charactersspecifies the number of padding characters that will be appended to each frame, toensure that the last significant character is sent before the data transmitter switches off.Poll Interval Timerspecifies the time between passes through the polling list.No Response Timeris activated after transmission of a general poll or a data frame. On expiry, a NAK–EOT–General Poll sequence is transmitted, and the No Response Retry Count is incre-
