having never done paging on a 2000 i am in need of some help in setting it up.

here's what i've got so far:

free co port. lens 0171

cmd 10-0171=d150

cmd 3000-150=60

cmd 3028-150=00

cmd 200-4=160 (will change this to a 2 digit code later. 4 was set to none)

cmd 3500-60=05

cmd 3502-60=3

cmd 3508-60=3

======================================

i can page by dialing a 4. but after 3-4 seconds i get a fast busy from the system.

speakers are valcom 24v amplified celing speakers connected to the co port and a 24v power supply.

also is there a way to page both internal phone sets (which they do now) & the external speakers at the same time??

The Co port needs a signal to keep it alive,
I usually have an amp or page interface that simulates a co interface. Your programming seems correct. The only way to have internal & external @ the same time is to tap off the spkr of an unused station. But w/ that setup there isn't 2 zones, just one.

3508>60>1

so i need battery on the co port then??

this other guy i used to work with thought that the 2000 would provide the battery....not true?

You can use a Valcom V2000A page control that will supply the talk battery that the 2000's loop start trunk needs.

Th only other way you could do it would be to use an E&M trunk interface but that is rather expensive and takes a lot of time to set up.

valcom would be the way to go.....a whole lot cheaper


thanks to all
