LW 19.3 PRI

Anyone know of a way to do more than 10 CPN Subs? I have 20 tenants on a
200, and I need to sub all 20 did ranges.

Oh... and were upgrading to PRI on our SX2000 ML... I haven't seen the CDE
for the PRI... are there subs for that?

Thanks!

I don't have my ISDN docs handy Dave, but whatever the max CPN
substitutions is, it's not expandable. If you have more than one ISDN span
you could always build some class of restriction (or interconnect
restriction) to funnel part of your tenants toward one hybrid and the rest
toward another. In that way you could effectively double the number of
available CPN subs. More work sure, but possibly a means to an end.

Both the SX2K and the SX200 PRI ISDN software is built from the same core,
both running on vxWorks. Features and limits will therefore be similar, if
not identical.

Really...That may or may not answer a question I had about a large mitel system
I bought that I'll probably need to reset the password on. Now I know there are
a number of ways to run VxWorks, both with a visible file structure or without.
Can the SX-200 be stopped at a boot monitor prompt (like VxWorks based systems
normally can be) and a file in the filesystem modified or deleted to rid it of
passwords? If so, which one is it?

I've done this before on other systems from other manufacturers.

On the SX-200ICP almost immediately after POST there's a 10-sec pause
(even an onscreen prompt with a 10-sec countdown) where you can hit any
key to interrupt it. I dunno about the file structure or if you can do
any tinkering, but you can definitely interrupt the boot process. That's
how you get in to set the network IP parameters. Type the "@" symbol
followed by the [enter] key to resume booting.

When you find out, let us know ;-)

Dave, we just today did some upgrades to several of our PRI cards for our
SX2K "farm". You might be interested to learn that in the most recent PRI
card loads that TWO HUNDRED (200) cpn subs are now supported. I'll have
to look at the docs to see what load of switch s/w is supported. Your LW19
box is surely OK, but your SX2K box may need that long overdue upgrade.
