Is there any source for Euracom PABX's in the US that anyone's aware of?
Also, how are spid's and ldn's assigned to devices on the internal BRI
connections? Must the PABX be connected to the PSTN?
I thought about trying a European ISDN PABX awhile ago, but could never find
answers for these questions.
Regards,

| Hi Tariq,
|
| I am in the process of setting up a Euracom 262 in my home lab. (This
| has 4 Bri ports, 1 external network facing ie to CO) the other 3 can be
| configured either for internal or external use. In our case internal
| use. It also has 6 POTS ports - in case you want to use stone-age
| modems!
|
| The Euracom supports multipoint on the S bus so although you only get 2
| B channels per S bus you can plug up to 4 S bus devices (routers, TAs,
| phones) into each port and make calls between any two at a time or a 2 B
| call from any one of them to a device on another S bus.
|
| -----------
| ! !------S1 to Telco CO
| S2-----! Euracom !
| ! PABX !
| S3-----! !
| ! !
| S4-----! !
| !---------!
|
| [ Each S bus S2, S3, S4 will support up to 4 S bus devices, or up to 8 S
| bus devices with 100R Bus terminating resistors ie a total of 12 or 24
| devices. However, remember that you only have a total of 6 B channels
| and a maximum of 2 B channels on each S bus. The connections are
| terminal screw blocks so you need some RJ45 sockets or flying leads]
|
|
| If you want to do multilink -PPP that is a feature of the end device not
| the ISDN switch. As far as the ISDN switch is concerned a multilink
| call is 2 separate independent calls that happen to originate on a
| single device and terminate on a different single device.
|
| I am intending to connect up a 2503, 2620 with WIC-BRi, 4500M with NP-
| 4B.
|
| The E1 to Bri device that I mentioned is an Adept-Q, it has 4 x Bri
| ports and a single E1 port. I do not have one of these as yet I am
| saving up! (They are about #1500, not to mention the cost of an NP-1CE1
| or NM-1CE1 module). According to the spec sheet it will act as a mini 8
| channel digital PABX.

|
| BTW which stream are you taking? I am working on the ISP Dial.
|
| Where abouts are you located?
|
| I am based in the Midlands
