NT7D16 Data Access card Page 429 of 894 Circuit Card Description and Installation In the case of outbo und modem pooling , the DAC answers the data call and drives the DTR lead ON (modes 0 and 1). Then the calling data module and the DAC form a transparent link betw een the calling DTE and the modem.
Page 430 of 894 NT7D16 Data Access card 553-3001-211 Standard 2.00 September 2004 Mode 0 This mode should be selected when th e D AC is connected to a modem, except Hayes-1200, for inbound and outbou nd modem pooling (see modes 2 and 3 for Hayes-1200 modem).
NT7D16 Data Access card Page 431 of 894 Circuit Card Description and Installation Auto-dial cap ability This feature is required when the modem is used for outbound modem pooli ng. It allows the modem to go off-hook and dial the remote number (such as Smartmod em Hayes-2400 or Bizcomp).

Page 436 of 894 NT7D16 Data Access card 553-3001-211 Standard 2.00 September 2004 Note: If Call Detail Recording (CDR) is required, use separate out bound and inbound Modem Pools. Mode 3 This mode should be selected when the DA C is connected to a Hayes-1200 modem for inbound Hotlin e operation.
NT7D16 Data Access card Page 437 of 894 Circuit Card Description and Installation • The equipment can monitor the DTR lead (optional, depend ing on the mode selected). In modes 4, 5, 6, and 7, the DAC: • operates as a DTE • monitors the DSR • monitors DCD control leads • drives the DTR lead The RI lead is ignored.
Page 438 of 894 NT7D16 Data Access card 553-3001-211 Standard 2.00 September 2004 Mode 4 This mode should be selected when th e DAC is connected to a gateway for inbound and outboun d operation.
NT7D16 Data Access card Page 439 of 894 Circuit Card Description and Installation In the outbound operation, the DAC dr ives the DTR le ad OFF until ano ther DM calls it for outbound accessing. The DAC answers the data call and drives the DTR lead ON.
Page 440 of 894 NT7D16 Data Access card 553-3001-211 Standard 2.00 September 2004 Mode 5 This mode should be selected when th e DAC is connected to an auto-answer gateway for inbound Hotline operat ion. In this mode, the D AC automatically executes Hotline operation when DCD is driven ON by the gateway.
NT7D16 Data Access card Page 441 of 894 Circuit Card Description and Installation Programing DAC for mode 6 in ser vice change LD 11 When used for inbound or outbound gateway access, the DAC can be configured as R232 in LD 11.

When the host turns DTR ON, the DAC answers the call. If DM-to-DM protocol exchange is successful, the DAC drives CTS, DSR, and DCD ON.
NT7D16 Data Access card Page 443 of 894 Circuit Card Description and Installation Dynamic control of DTR This feature is required only if the host must be capable of releasing an established call. The host shou ld be able to drop an established data call by driving DTR OFF for more than 100 ms .

NT7D16 Data Access card Page 445 of 894 Circuit Card Description and Installation This mode should be selected when the DA C is connected to a host and continuous Hotline operati on is required. In this mode, th e DAC repeatedly tries to Hotline to the Autodial DN as long as DTR is ON.
Page 446 of 894 NT7D16 Data Access card 553-3001-211 Standard 2.00 September 2004 unless the DTR lead is driven ON by the termin al. Any terminal that drives the DTR lead ON can be used with this mode (such as VT100 or VT102). The DAC drives CTS, DSR, and DCD ON, except when a call is dropped or when control—Z is en tered during th e idle state.
NT7D16 Data Access card Page 447 of 894 Circuit Card Description and Installation Mode 13 This mode should be selected when the DA C is connected to a terminal (DTE) and Hotline call origi nation is required. This mode is simila r to the operation of the ASIM when set to not-forced-DTR and Hotline.
Page 448 of 894 NT7D16 Data Access card 553-3001-211 Standard 2.00 September 2004 Mode 15 This mode provides a “virtual leased line” and the meaning of the “Forced DTR” switch is re-defined. This mode should be selected when the DA C is connected to a terminal (DTE) and continuou s Hotline call origin a tion is required.
NT7D16 Data Access card Page 449 of 894 Circuit Card Description and Installation Note: If AUTB is set to ON, the BAUD parameter is not prom pted. If AUTB is set to OFF, you may select a fixed baud rate in response to the prompt BAUD. When the DAC receives a call, it adapts to the caller’s baud rate.
