- First of all a plug. As mentioned a while ago, we did start up a
- mailing list for Northern Telecom switches, anybody who wants to join
- should send mail to telswitch-nt-request@dg-rtp.dg.com.
-
- I should think going off-hook every two minutes would give your PBX a
- nervous breakdown. There are only so many slots configured to provide
- dial-tone, and when you go off-hook you compete for one of those.
- Everybody going off-hook every two minutes, I expect lots of people
- would not get dial-tone at all.
-
- Sounds like your company balked at paying $25 for replacing your
- phones with new phones with message waiting lights. What you need to
- do is retro-fit your phones with lights. You can do this in many ways,
- places like Graybar will supply just the LED, or a new faceplate with
- the LED installed, or gadgets with modular jacks that will plug into
- your phone line. All these will respond to the 90 to 130VDC that the
- PBX will put on your line when you have a message waiting.
-
- Note that having a message waiting light or stutter dial-tone is an
- either-or option; you can't have both. The people who administer your
- PBX will have to switch each line from stutter dial-tone to message
- waiting light as you equip the phones.
-
- Hope this helps.
