How to make a call? ----------------------------------------------------------------------------- A13. You can use the following two ways to make a internal fax/modem call, ISDN call or a/b adapter call. (1) Using the conventional dialing command ATD, ATDT or ATDP AT&O0ATDs dial for internal fax/modem call AT&O2ATDs dial for ISDN data call AT&O3ATDs dial for a/b adatper * S is the phone number (2) Using a prefix after ATD for a quick dial: ATDMs dial for internal fax/modem call ATDIs dial for ISDN data call ATDBs dial for a/b adatper * The prefix M means making a "Modem" call * The prefix I means making a "ISDN" call * The prefix B means making a "a/b adapter" call * S is the phone number ============================================================================= ============================================================================= Q14. How to set the calling-party-number/subaddress for each outgoing service? ----------------------------------------------------------------------------- A14. Each type of OUTGOING call can be assigned by "AT&ZOx=cgpn/cgsa/" command, where x="M" (for internal fax/modem call) x="I" (for ISDN data call) x="B" (for a/b adapter call) cgpn=Calling Party Number (= MSN for outgoing calls) cgsa=Calling Party Subaddress (= SA for outgoing calls) So, you can assign your own number by this way: AT&ZOM=cgpn/cgsa/ (cgpn/cgsa/ = your subscriber number and subaddress) AT&ZOI=cpgn/cgsa/ (cgpn/cgsa/ = your subscriber number and subaddress) AT&ZOB=cgpn/cgsa/ (cgpn/cgsa/ = your subscriber number and subaddress) remember: the calling and called party numbers are defined always without the local area prefix, eg: the ISDN number is +43-1-4941522 then the CGPN/CDPN is just the "4941522" example: AT&ZOM=4941522/123/ calling party number & calling party sa AT&ZOI=4941522/456/ calling party number & calling party sa AT&ZOB=4941565 calling party number only With the command "AT&ZO?" you will receive the list of the currently installed number assignments for outgoing calls. With the command "AT&ZOx=//" you can delete each specific entry so that no calling party number & calling party subaddress will be sent in the outgoing call. ============================================================================= ============================================================================= Q15. What specific "Bundle two B channels" protocols are implemented in Elite 2864I to support either for 112Kbps or 128Kbps data transmission? And how to charge? ----------------------------------------------------------------------------- A15. The basic rate ISDN consists of three logical channels(2B+D). Each B channel can be used independently for a dial up connection with either 56Kbps or 64Kbps line speed. Elite 2864I can "Bundle" two B channels together to have 112Kbps or 128Kbps data rate. The following "Bundle" protocols are implemented in Elite 2864I: (0) X.75 "Multiple Link Protocol"(MLP): please refer to the AT&J3S100=0 command (1) "cFos Channel Bundling" (CCB): please refer to the AT&J3S100=1 command (2) PPP MP: Not available yet, it will be F/W upgradeable in future. The charge for bundle connection is twice of single B channel. ============================================================================= ============================================================================= Q16. How does Elite 2864I use the two B channels? ----------------------------------------------------------------------------- A16. The Elite 2864I has one data port and one voice port, you may use one B channel for data call, and the other B channel for voice call at the same time. Or you can bundle both the two B channels for data call. ============================================================================= ============================================================================= Q17. I have problem to send fax from fax software. It always sets hardcoded prefix with ATDT command and can not accept ATDM command. How to solve this problem? ----------------------------------------------------------------------------- A17. You shall set initial string with AT&F&O0&L1 command for Elite 2864I. This command will automatically set a default fax/modem call for dial in and out. In this case, you can avoid to use ATDM command to specify a fax/modem call and ATDT command will then make a fax/modem call. ============================================================================= ============================================================================= Q18. I bought an Elite 2864I and I have the problem to configure it for Remote Access Service on Windows NT, please help. ----------------------------------------------------------------------------- A18.

I am a BBS sysop, I am in trouble my Elite 2864I rings to the second global call while the first call is running. To avoid the mistake that the second caller may think my system hang, if it is possible to disable the second call that routes to a/b adaptor. ----------------------------------------------------------------------------- A25. Yes, this second global call will route to a/b adaptor, but you can use S118.6=1 to forbid the a/b adaptor to accept the incoming global call if you do not any analog modem attacted with it. ============================================================================= ============================================================================= Q26. How to configure Elite 2864I with my BBS system ? What's the suitable initial string? I have two ISDN numbers, 346321 and 346322 for ISDN data call and fax/modem call. ----------------------------------------------------------------------------- A26. Generally, AT&F&L1S84.4=1 is enough for data call. For data+fax BBS system, you can set AT&F&L1S84.4=1#B1+FCLASS=6 There is a AT command AT&ZIn to set the MSN numbers. You can set your two MSN numbers by this way: AT&ZI0=346321 -->for ISDN X.75 data call AT&ZI1=999999 AT&ZI2=999999 AT&ZI3=999999 AT&ZI4=999999 AT&ZI5=999999 AT&ZI6=346322 --> for fax/modem call AT&ZI7=999999 The other MSN set by 999999 won't answer any way. ============================================================================= ============================================================================= Q27. I have two Elite 2864I connected to the same one S-bus, and the MSN numbers for this S-bus are 6223001, 6223002, 6223003, 6223004. How to set the MSN numbers for both two Elite only answer the ISDN data call and fax/modem call? ---------------------------------------------------------------------------- A27. You may set your two Elite as this way: +-------Elite AT&ZI0=6223001 for X.75 data call | AT&ZI6=6223002 for fax/modem call NT---S bus--+ AT&F&L1S0=1 set as initial string | +-------Elite AT&ZI0=6223003 for X.75 data call AT&ZI6=6223004 for fax/modem call AT&F&L1S0=1 set as initial string ============================================================================= ============================================================================= Q28. There are 10 Elite 2864I in our bank for dial out only. Therefore, we don't want the Elite to act for any incoming call. Is there any way to disable it? ----------------------------------------------------------------------------- A28. Yes, we know some institutes may need this special function, so we implemented one S register to reject the incoming call. It is ATS118.0=1 ============================================================================= ============================================================================= Q29. We are the ISDN INTERNET service provider. Is it possible to disable the fax/modem function in Elite, and let it work like as a pure ISDN TA ? ----------------------------------------------------------------------------- A29. Yes, as far as the ISDN ISP concerned, they maybe don't need the internal fax/modem function. So, we use one S register to disable the internal fax/modem function and let it work like a TA without fax/modem. It is ATS118.7=1 ============================================================================= ============================================================================= Q30. I connect my Elite 2864I to a NT1, but after power on self-test, the B2 LED keep flashing. I can not dial out and also no possibility to answer a call, please help ! ----------------------------------------------------------------------------- A30. It seems to be the problem of layer 1 configuration. Sometimes TE need to add the "Termination Resistors"(you may refer to ITU-T I.430/Figure 2). There are two resistors in the figure, one is built in NT1, another is built in the farthest TEn (n=0-7) that connects to NT1. The jumper JP1 and JP2 on the ISDN module of Elite are used to selecting TR. So, our suggestions are: a. if wiring configuration is point-to-point, it means only one Elite 2864I is connected to NT, then it is necessary to enable the TR by shorting JP1 and JP2 on Elite. b. if the wiring configuration is point-to-multipoint, you must choose one of the TEs to add TR, the farthest one from NT is recommended. +------TE0 S/T | NT1/TR --------+---------+------TE1 : : +------TE7 ============================================================================= ============================================================================= Q31. Which setup do I have to use on my computer for the Elite 2864I to work my INTERNET Providers ISDN router? ----------------------------------------------------------------------------- A31.
