automatisation of PABX (OXE) backup: modem and/or IP

[krzysioD]

hello,

we've reached some problem, we currently have some (10+) pabxes that we need to do time-to-time backups.

if OXE is connected to internet, and ssh port is not firewalled, we could have some cron job on oxe to do ssh/scp to our site.

but if we have only modem (v.34) it realy makes some trouble.

1st: connection from RMA board to CPU is 9600. Modem connects usually at 31400-33400, we waste a lot of bandwith, is there a possibility to program eRMA in NPRA/PRA2/E1 board? May it be possible to use full ISDN speed (64 kbps ???)

2nd: automatisation: i tried to write simple linux expect (http://expect.nist.gov/) script, but interfacing kermit and modem makes it very difficullt. Maybe someone has a solution ? It could be commercial, some demo/shareware is OK.

any hints?

Guys, if anyone has similar problem. Use expect (unix/linux tcl/tk script/extension).
expect uses scripts like that:

log_file expect.log
spawn telnet 10.10.10.10
set session_for_modem $spawn_id
send_log "[exec date]: session for modem begin with ID: $spawn_id \r\n"
expect "ogin: "
send -- "mtcl\r"
expect "word: "
send -- "mtcl\r"
expect "> "

You could do any of expect/send and run ckermit or dial with modem

if they have a 4760 server use that to for centralised backup's and if you need to push off site use sftp to your server

[krzysioD]

Does 4760 allow for automatic modem dialup to my central site, and receive callback from me?

because i don't have IP access to PABXes.
Only dialup modem, by RMA access.

You can set up a SLIP link with the 4760 and the remote systems

[krzysioD]

will you be so kind to provide me TC number or a keyword in docs?
OXE docs or is this in OV documentation?

does SLIP link have more than 9600 bps

[knightr1der]

All the documentation you need is in the 4760 setup CD under CDroot> tools > documentation > installation manual_EN.pdf

When you declare the PCX in the 4760 technical directory, choose link type SLIP instead of IP. You also need to set up SLIP on the PCX. As for Speed, default speed is 9600 but I think this can be increased slightly - not too much - but then this is the drawback for dialup networking.
