    Although the ISIHP-2S/2U contains four ISDN TA ports and four analog modem ports, only four ports can be active at any one time (because only four B-channels are present). See Figure 1-1. The ISIHI-2S/2U function like the ISIHP-2S/2U units but have an ISA-type bus which requires manual setting of the I/O address and the interrupt request (IRQ).

    The terminal adapters on the ISIHP-4SD can make eight simultaneous independent connections. From the perspective of the server PC, the ISIHP-2S/2U (or ISIHI-2S/2U) is an eight-port serial card with eight devices permanently attached to the serial ports (Figure 1-1).

  • Page 9: Isihp-4S/4U Serial Card

    1.1.2 ISIHP-4S/4U Serial Card From the perspective of the server PC, the ISIHP-4S/4U is an sixteen-port serial card with sixteen devices permanently attached to the serial ports (Figure 1-2). Figure 1-2. Modems and Terminal Adapters of ISIHP-4S/4U (for ISIHP-4SD, no modems are present) The first eight ports are the four terminal adapters, each of which appear as two ports.

    port while calls are being held off will not be rejected nor will RING messages be given. Rather the digital call will be held in an alerting state until !Hn times out at which point the call will begin the normal ringing process. Digital calls originated from that port while the !Hn timer is running will abort the timer and the call will go out immediately.
  • Page 109 *!Hn Analog Call Hold-Off Time Unit: 1 second Values: n=0 (disable), n=1-255 (1-255 seconds) Default: *!H0 (disabled) When an analog call disconnects a timer will be installed that will hold off incoming analog calls for the given amount of time (n) for that analog port. Analog calls that are received by that port while calls are being held off will not be rejected nor will a ring be given.

  • Page 110: Terminal Adapter S-Registers

    Terminal Adapter S-Registers S-registers are sections of memory in which values are stored that affect how the TA operates. S-registers are so- called because each has a name that begins with the character S. Use the S command to assign a value to or to read the current value of an S-register.
  • Page 111 S0 Number of Rings Until Answer Unit: 1 ring Range: 0–255 Default: 1 Sets the number of rings the TA waits for before it answers and begins its connect sequence. S0=0 turns off the ability to automatically answer a call. S0=1 causes the TA to automatically answer after 1 ring.

  • Page 114 TA determines the type of call by checking for protocol information in the SETUP message or by matching protocol information received on the B-channel once connected if no protocol information is available in the SETUP message. Once the protocol is determined, the TA will switch its data protocol to match.

However, 3.1 kHz audio information transfer capability is allowed on data lines (modem or fax) by most switches. S55 also lets you define whether a progress indicator information element (which indicates that the origination address of the POTS call is non-ISDN) is sent with the SETUP message for the POTS port call.

  • Page 120: Answering A Call

    Dialing To dial a number using AT commands, you must first start a data communications program. In the program’s terminal mode, type ATDxxxxxxx<cr>, where xxxxxxx is the telephone number you want to dial, and <cr> is the carriage return character that is sent when you press ENTER , e.g, ATD7853500<cr>. The dial string can contain up to 80 characters.
  • Page 121 Chapter 5 - AT Commands The TA answers the call after the number of rings specified by S0. To disable autoanswer, use a configuration utility or the command S0=0. Note: If the user wants to accept calls while DTR is low, the TA must be configured to ignore DTR. To ignore, enter AT&D0<cr>.
