1309.0. "PPP over private line" by VAXRIO::TULA () Tue May 20 1997 20:14

    Hi,
    I'm in the middle of a project that is trying to use a brouters90t2
    talking ppp over a 64kbps private line.  It is going to use the v.35
    port.  On the other side is going to be a host with windows 95 that
    intend to speak with this brouter using the line with ppp.
    Some people said that this kind of configuration works, others said
    that don't.  Can somebody clarify this?
    How can i configure the brouter90t2?
    Thanks,
    Tula

 Ok and the Modem you are connecting the DECbrouter to is a synchronous
 modem? or a CSU/DSU?

 You can't communicate with a DECbrouter directly from a Windows 95
 system or for that matter any end system. You'll need a router at both
 ends of the 64kb link. Unless you are connecting your PC to an X.25
 network using a PAD or Frame Relay network using a FRAD. In which case
 you could possibly tunnel PPP through the network link.

 What exactly are you trying to accomplish with the DECbrouter?

 Maybe you should be looking into a Terminal Server which supports
 IP Services and PPP.

1309.2trying to clarifyVAXRIO::TULAMon May 26 1997 22:5211
    I'm connecting the DecBrouter to a synchronous modem.  
    At the other side, i have another synchronous modem and an interface 
    ACB56(producer SeaLevel) V.35.
    All the products have been already sold, so you have suggested the
    terminal server because this solution don't work or because it is cheaper?
    If it doesn't work,can you explain me why?Is the ppp encapsulated at 
    other level 2 protocol?
    Thank You

1309.3Hmmmm Should work but I've never done itFOUNDR::SHEEHANTue May 27 1997 18:0739
 Hi Tula,

 According to SeaLevel the SEALEVEL ACB 56 provides the PC with two
 communication ports, a single Synchronous Asynchronous channel
 jumper selectable as RS-232 or V.35.

 Now if the ACB56 is configured for Sync and is running PPP
 over the Sync correctly and the call takes place to your DECbrouter
 then the DECbrouter interface should come up. If this happens then
 the connection is established. Next step is to see if the line
 protocol PPP comes up. You can see the state on the DECbrouter
 by doing a "Show interface"

 If this occurs and IP is enabled on the appropriate interface then
 DECbrouter should communicate with the Windows 95 system. Although
 I've never done this, I don't see any reason why it should not work
 if the line protocol comes up ok then PPP is working between the 2
 systems.

 A good test would be to try and connect 2 Windows95 systems with
 ACB56 Sync Modems together and seing if it works with Microsofts
 PPP.

 My reason for mentioning the Terminal server is due to it having
 Async ports for modem connections. I was not aware that you had
 a Sync Modem in the Windows95 System. Also a DECbrouter is a very
 expensive method of connecting a remote single end system to your
 network. An Access "Terminal" Server would be much cheaper and allow
 more client systems to connect.
