12 1.3 A T ypical Application A typical application for a MultiFRAD 100-Series is connecting a single non-frame relay device to a frame relay network. The MultiFRAD 100- Series is usually used at a remote site where a single DLCI and a single device needs to be connected to a frame relay network. A MultiFRAD 100-Series can connect any existing sync[...]

13 your capability to present data to the local telephone switch. Y our capability to present data is determined by the internal DSU (Data Service Unit) that can transfer digital data at a maximum rate of 56,000 bits-per-second to the network. A general rule of thumb in this scenario is to assign a CIR of 32K bps and an excess burst rate (Be) of 24[...]

56 5.3 Data Port Configuration This dialog box allows you to configure the data port. Y ou will be able to set the parameters required for the successful operation of the port. Mode Asynchronous/Synchronous This allows you to set synchronous or asynchronous parameters required for transferring data between the MultiFRAD and the data port device. Th[...]

57 Note: The MultiFRAD always provides the clocking signal to the sync device. The MultiFRAD 100's data port can not be set to external clocking, it is always internal clocking. Between Frames The Between Frames parameter must be set to match the idle condition of the synchronous device connected to the data port. The Between Frames determine [...]

58 CRC Preset The CRC Preset parameter allows the user to specify whether the polyno- mial used to calculate the CRC for each frame is preset to all 1s or all 0s. This option must match the synchronous device’s CRC-preset setting. The default is All 1s. Async Mode Parameters Following Parameters are modifiable when the device connected to the dat[...]

59 Parity The Parity parameter sets parity for odd, even or none. Under normal conditions, parity is set to none. The default is none. Stop Bits The Stop Bits parameter sets the number of stop bits. The number of stop bits can be 1, 1.5, or 2. The default is 1 bit. Flow Control The Flow Control parameter allows for two types of flow control: the so[...]

60 Pass Xon The Pass Xon parameter enables the XON/XOFF flow control signals to be passed on to the data device. This option has to be used in conjunction with the software-based XON/XOFF flow control option. The default condition is for this option to be turned off, and normally it should remain off. Echo The Echo parameter enables data entered on[...]

61 ENQ/ACK The Enq/Ack parameter is a special flow control protocol used in Hewlett Packard computer systems. This option is sometimes referred to as Enquire/Acknowledge flow control because it’s based on the computer sending an enquiry (ENQ) and then expecting an acknowledgment (ACK).[...]

62 5.4 T runk Configuration This dialog box allows you to configure the trunk. Y ou will be able to set the parameters required for the successful operation of the trunk. Frame Relay is a multiplexing protocol designed to operate over transmission facilities that are virtually error free. In Frame Relay , frames are routed through the network on th[...]

63 LMI describes a protocol and associated procedures operating on the local interface between the user and the network. It notifies the user of the addition, deletion, and presence of the PVC in the network. It also notifies the user of the end-to-end availability or unavailability of a PVC. Basic LMI protocol is based on a synchronous polling sch[...]

64 Full Status Counter The Full Status Counter determines how may Polling Intervals take place before a full status is requested from the network. A full status enquiry message is sent from the MultiFRAD to the network requesting a status report of the PVC on the physical link. The Full Status Counter can range from 1 to 255, with a default of 6. E[...]

65 Back to Back The Back to Back is used to test the port by connecting two MultiFRADs together without a frame relay network in between them. Back-to-back mode still requires the use of DSU/CSUs, but they should not be connected over the frame relay network. The options are On and Off with a default of Off. Back-to-back mode is useful when two Mul[...]

66 5.5 Statistics This dialog box allows you to view status of the trunk. Its possible to view signal status and other characteristics like data frames transmitted or received, status of enquiries transmitted and messages received and the status of the messages received. If you want to clear the statistics so that you can have fresh statistics, the[...]

67 Loop Tests The loop tests provide a short and long loop test. The short loop test is the data port loopback test which loops back the data from the data port to the sending device (DTE). The long loop test is the trunk loopback test which again receives data from the DTE device and loops it back from the internal DSU. The data port loopback test[...]

73 The W ord Length option sets the number of bits in a word. The word length range is 5 to 8 bits. The default is 8 bits. The Stop Bits option sets the number of stop bits. The number of stop bits can be 1, 1.5, or 2. The default is 1 bit. The Parity option sets parity for odd, even or none. Under normal conditions, parity is set to none. The defa[...]

74 The EIA Pass Through option allows the data device to receive EIA control signals through the MultiFRAD. This option only applies during the async mode of operation. Since, in normal interactive operation, the existence of a MultiFRAD should be transparent to the user , the EIA pass through option allows a terminal to operate as if it were conne[...]

75 6.2 .2 Sync Data Port Configuration The Sync Data Port Configuration menu allows you to configure the data port for either asynchronous or synchronous operation, depending on the type of device connected to the port. When the port is configured for synchronous operation, the following Data Port Configuration menu displays the default parameters:[...]

76 ing, data is represented normally . With NRZI encoding, a logical one is represented by no transition and a zero is represented by a transition at the beginning of the bit. Most synchronous devices can be configured for either NRZ or NRZI. If a synchronous device is not configurable, it most likely is set to NRZ. Refer to the device’s user doc[...]
