No I cant! But I can tell a litle about the 9150.
First of all, the 9150 can handle up to 32 digital phones and 1 analog port.
The digital phones is your normal digital phones like 2616, 3110, 3310, 3820, 39xx..
The digital sets are programmed the same way as the are on the main site. They are just extended from your system to another location via your IP network or ISDN BRI.
The 9150 Remote gateway (remote office) and the RLC card wich is installed on the main site can normaly handle 8 simultaneous calls.
It has a built in DSP card for 8 calls.
If you need more simultaneous calls you have to add DSP cards in the 9150 and the RLC card.
(Every DSP card adds 8 more calls, but has to be installed in both ends)
But if the (up to) 32 phones isnt used so much maybe 8 simultaneous calls is enough.
The 9150 can be connected to the main site via IP (lan/wan) or via ISDN BRI.
For BRI connection there is also a need for extra BRI cards inside the 9150. (not at the RLC card)
You can also use both IP and ISDN.
Primary could be IP but as a backup you can use ISDN.
Or you can reach main office via IP and dial out via ISDN.
There are many options..
Dont forget Quality of Service on the IP connection!
