FSU User Manual 61200.130L1-1 Chapter 6. DTE Port Configuration Poll/Response Timeout (TIMEOUT) For multi-point configurations, set the amount of time the FSU waits for a poll response before issuing another poll. Poll/Response Timer Threshold (THRESHOLD) For multi-point configurations, set the maximum number of response timeouts allowed before a session is terminated. Slow Poll Ratio (POLL RAT) Determine how often devices on the Slow Poll List are polled. This list is automatically managed based on poll timeouts. Initially, all controllers are on the Normal list. When a controller times out a fixed number of times, it is moved to the Slow Poll list. A controller remains on this list until it responds properly to a poll. The number entered is the number of times controllers on the Normal list are polled before controllers on the Slow Poll list are polled. Enter 1 to disable this option. Protocol Address Table Unit Address (UNIT ADDR) For a multi-point connection, enter the unit address used for specific unit identification. The address may consist of a maximum of seven alphanumeric characters. There must be one alphabetic character for this parameter so the FSU can use the upper case version for the port address and the lower case version for the select address. LLC2 SSAP (LLC SSAP) Defines a point-to-point connection on the network. For each bisync SDLC connection, the SSAP of one FSU should match the DSAP on the other FSU. LLC2 DSAP (LLC DSAP) Define a point-to-point connection on the network. For each bisync SDLC connection, the DSAP of one FSU should match the SSAP on the other FSU. See the section SNA/SDLC with Local Spoofing in the chapter Applications for a configuration example which demonstrates the SSAP and DSAP arrangement. 61200.130L1-1 FSU User Manual Chapter 6. DTE Port Configuration Outgoing DLCI (OUT DLCI) Enter the DLCI address used to connect with the remote device across the frame relay network. Edit Next Entry (NEXT key on front panel) Edit the next entry in the address table. Edit Previous Entry (PREV key on front panel) Edit the previous entry in the address table. Delete This Entry (DEL key on front panel) Delete the current entry in the address table. Add New Entry (ADD key on front panel) Add a new entry to the address table. FSU User Manual 61200.130L1-1 Chapter 6. DTE Port Configuration Transparent Async Protocol (TRANS ASYNC) Transparent Async protocol frames up async characters to transport across a frame relay network. This protocol is used when the device connected to the FSU is an async device such as a terminal or PC. See Figure 6-8 for the Transparent Async menu tree. 1 PROTOCOL 6 TRANSPARENT ASYNC 1 DTE PORT 1 2 PHYSICAL LAYER OPTIONS 1 INTERFACE TYPE 1 RS232 1 CONFIG 2 V.35 2 DTE PORT 2 1 2400 bps 2 ASYNCHRONOUS BIT RATE 2 4800 bps 3 9600 bps 4 19.2 Kbps 5 38.4 Kbps 3 DATA BITS 1 7 2 8 1 NONE 4 PARITY 2 EVEN 3 ODD 5 STOP BITS 1 1 2 2 6 HARDWARE FLOW CONTROL 1 OFF 2 ON 3 PROTOCOL OPTIONS N/A 4 PROTOCOL ADDRESS TABLE 1 FAR END PORT NUMBER 1 DTE PORT 1 2 OUTGOING DLCI 2 DTE PORT 2 Figure 6-8 Transparent Async Protocol Menu Tree The FSU buffers async characters from the DTE device until two idle characters or 100 characters are received. A frame relay synchronous frame is constructed containing the data content of each character. Frame relay frames received on the network containing transparent async data are transmitted to the attached device with the character format set under the DTE port physical layer options. 61200.130L1-1 FSU User Manual Chapter 6. DTE Port Configuration No control lead status or break characters are transmitted across the frame relay network. Physical Layer Options Interface Type (CONN) Select the connector type for the DTE interface. The choices are V.35 and RS-232. Asynchronous Bit Rate (BIT RATE) Select the operating speed to match the DTE device connected to the FSU. The selections are 2400 bps, 4800 bps, 9600 bps, 19.2 kbps, and 38.4 kbps. Data Bits Select the byte length to match the DTE device connected to the FSU. The choices are 7 and 8. Parity Select even, odd, or no parity information. Set to match the DTE device connected to the FSU. Stop Bits Select one or two stop bits. Set to match the DTE device connected to the FSU. Hardware Flow Control (HDW FLOW CTRL) When enabled, the FSU uses CTS to temporarily disable transmit data to the FSU. Protocol Options Protocol options are not available when the Transparent Async protocol is selected. Protocol Address Table Far End Port Number (FE PORT) Enter the remote FSU port number that the remote device is connected to. FSU User Manual 61200.130L1-1 Chapter 6. DTE Port Configuration Outgoing DLCI (OUT DLCI) Enter the DLCI address that identifies the virtual circuit used to connect with the remote FSU. PPP Synchronous Protocol (PPP SYNC) PPP Synchronous protocol provides a PPP device access to the frame relay network and also routes IP traffic from the network to the PPP device. See Figure 6-9 f...
