8. Parameter 5 Ancillary Device Control Parameter 5 specifies whether or not flow control of the local DTE device ancillary device by the PAD can occur and if so what modes of the PAD the PAD flow control of the local DTE are allowed Flow control of the local DTE device is handled in conjunction with S54 DTE flow control register The type of flow control the PAD transmits to the local DTE device is set according to the setting of S54 For example if S54 is set for CTS flow control the PAD will flow control the local DTE device by turning off the CTS pin when the PAD can no longer accept any characters from the local DTE When the PAD can resume accepting characters from the local DTE the PAD turns the CTS pin on If all DTE flow control options are disabled default the PAD will transmit XON Ctrl Q and XOFF Ctrl S to the local DTE for flow control Table 12 11 Ancillary Device Control Value Description 0 No PAD flow control 1 PAD data transfer flow control 2 PAD data transfer and PAD command mode flow control default Note The function of parameter 5 differs from the 1984 CCITT X 3 Specification The specification indicates that only XON and XOFF can be transmitted to the DTE for the purpose of flow control The TA does not restrict the type of flow control used on the local DTE The setting of the AT command indicates the type of flow control sent to the DTE Thus if the DTE device only re

While the softload is in progress the TA remains fully operational TA SOFTWARE ARCHITECTURE Software Sets Software Format The concepts of sets of software and how the TA s Central Processing Unit CPU use them are described below The TA has two sets of operational software the active set and the alternate set The TA operates from the active set and performs software downloads into the alternate set A swap command allows the user to swap software sets at any time The active software becomes the alternate software and vice versa This swap also allows the unit to return to its previous version of software The active software set selected is stored in a separate nonvolatile memory location and is retained even after powering down the unit Swaps to invalid software are prevented If a power up occurs in an invalid set of software the TA automatically swaps to the alternate set of software Updated software for the TA is provided on a standard PC compatible 5 25 high density floppy diskette The host computer can be a PC on any other system capable of reading PC formatted floppy disks and transferring files via YModem G UTA220 UTA220k 13 1 Softload The TA software file contains an ASCII coded header which can be displayed to verify the software s product and version information before initiating the softload On DOS based PCs this can be accomplished with the command For example to view the heade

Interface Terminal Adapters Several types of ISDN network services are available The most common is Basic Rate Interface BRI BRI provides two B channels bearer channels and one D channel used to place and release calls on the network B channels which operate at 64 kbps full duplex carry end to end data between network terminals B channels can be either circuit switched dial up allowing each call to be placed to different endpoints or permanently connected nailed to a single endpoint In some applications B channels can also be used to carry packet switched data where each frame of data can dynamically be sent to different network users The TA does not support packet switching on a B channel The D channel is primarily a control channel between the network and the terminal device such as a TA Terminal adapters attach standard data terminals and voice telephones to the ISDN allowing them to send and receive calls and data via the ISDN Some terminal adapters but not the UTA220 support voice service allowing a standard analog telephone set to be connected to the ISDN The UTA220 operates on the ISDN BRI It provides circuit switched data communications using circuit switched B channels for data and uses the D channel for signaling only ISDN Basic Rate Interface Points 4 2 BRI points and the associated devices found on customer premises are shown in Figure 4 1 The boxes in the diagram represent devi
