Configuration Stuff

Bitsurfer Pro

Here are some basics for the Bitsurfer Pro. First, if you need to check any of this, I recommend that you go into terminal rather than use the Configuration Manager that comes with the Bitsurfer Pro. I say this because there are to many buttons 'n stuff that can be rather confusing IMHO. The Bitsurfer Pro is a well advertised piece of hardware so you are likely to see these more than other devices.

A lot of this is shamelessly copied, though reorganized, from the Bitsurfer Pro Manual.

Active Profile

The active profile holds the current options settings and is used by the Bitsurfer Pro for all operations and functions. When options are changed, the active profile is changed.

Stored Profile

When the most suitable active configuration is established, it can be saved in a stored profile to be recalled on powerup or loaded back into the active profile at any time.

AT>Z Restores switch options from the stored profile and restarts the network (equivilent to a power cycle).

AT>W Save switch and global options to stored profile (a powerful write...sorta like AT&W).

ATI8 Gives you all sorts of information on the box...one notable bit to look for is the "Software Revision" which needs to be at least 1D to work with a netcom account. Latest revision, as of writing this, is 1F.

AT>V=C Gives you DN (Directory Number...the phone number), SPID (Service Profile IDentifier) and TEI (Terminal Endpoint Identifier...don't touch) information for both stored and active profiles. Will look like the following:

DATA PORT DN, SPID, AND TEI

   ACTIVE	  !N1=		  !C6=			  !D3=255
   STORED         !N1=            !C6=                    !D3=255

POTS PORT 1 DN, SPID, AND TEI

   ACTIVE        *!N1=           *!C6=                   *!D3=255
   STORED        *!N1=           *!C6=                   *!D3=255 

POTS PORT 2 DN, SPID, AND TEI

   ACTIVE       *2!N1=          *2!C6=                  *2!D3=255 
   STORED       *2!N1=          *2!C6=                  *2!D3=255 

OK

The important things here are the DN's and the SPID's. For a AT&T 5ESS Point to Point line you DO NOT put in any SPID's. The DN's are optional in any case and do not affect the usage for our purposes. If you want to, however, recieve in calls, you'll want to put the DN's in.

If you have ANY of the other switches, you'll need the SPID's in. The Data Port SPID and the Pots Port 1 SPID's will be the same. You put the Primary SPID in here (the first on the phone company gives you) and then you put your second SPID in the Pots Port 2 slot.

AT>V=G Will display the Global Configuration (Switch Info) and will look like the following:

SWITCH:
!C0=0 !C1=1 !C4=0 !C5=0 !C9=0

FEATURE ACTIVATORS:
!V3=60 !V4=62 !V5=61 !V8=63

You should be concerned ONLY with the !C0= and the !C1=.

!C0= gives you the switch type they have set.
!C0=0 is for a AT&T 5ESS for which you have two possible configuaritions given to you by the !C1= register.

!C1=0 is for a Point to Point configuration
!C1=1 is for a Multipoint configuration.

!C0=1 is for DMS-100 switches (Norther Telecom...icky) for which you have two possible configurations.

!C1=2 for PVC IC-0
!C1=3 for PVC IC-1 (it'll be this in most cases)

!C0=2 is for the National ISDN (NI-1) which only has one configuration

!C1=4 for the National ISDN-1

That is all on the configuration side of things...the next section has to do with what is needed for placing a call and using MultiLinkPPP.

AT%A2= selects the rate adaption protocol.

AT%A2=2 is for V.120 rate adaption protocol. You will select V.120. It is very similar to the V. protocols in modems but provides a rate adaption of up to 128Kbps, though there is no prevision in the RFC for making a multilink call over V.120. Shell users would want to use V.120 protocol to connect to their shell via ISDN.
AT%A2=95 selects a rate adaption protocol of PPP.

There are other selections for rate adaption protocol but you need not be concerned about them for a Ziplink ISDN connection.

AT%A98= selects the type of call initiation. There are two of interest.

AT%A98=S sets up the call for SpeEch which is what you want for DOVB.
AT%A98=D sets up the call for ISDN Data which is metered in Nynex and SNET land

AT@B0= selects the number of b channels to attempt to use. This will either be 1 or 2.

AT@B0=1 selects one channel.
AT@B0=2 selects two channels.

AT@M2= turns PAP on or off inside the box (meaning it requests PAP on connection rather than waiting for the stack to do it).

AT@M2=P turns PAP on.
AT@M2=N turns PAP off.

AT%A4=This sets the bps rate for the call which can be either 56K or 64K.

AT%A4=1 is for 56K.
AT%A4=0 is for 64K.

So, in brief, if you want to make a Multilink PPP call you'd need at least the following string:

For ISDN Data AT%A2=95@B0=2@M2=P%A98=D%A4=0&D2

For DOVB AT%A2=95@B0=2@M2=P%A98=A%A4=1&D2

If you want to place a call with V.120 you'd need:

For ISDN Data AT%A2=2@B0=1@M2=N%A98=D%A4=0&D2

For DOVB AT%A2=2@B0=1@M2=N%A98=A%A4=1&D2

[Note the &D2...I put this in because some terminals WILL NOT hang up if this is not there.]

In addition to using that string for Multilink PPP, you'll need to tell the Bitsurfer Pro to dial the ISDN number twice in the following manner:

ATD14082491433&14082491433

[Note, also, that I put in the full 11 digit phone number. I recommend that you ALWAYS do this, however, there are a few areas where this will not work, so be advised.]
