On the DMS side of the aisle, Ribbon is using the C15 and C20 softswitches. We collapsed two DMS10 switches into a single C15. The nice thing is the C15 is capable of still supporting the DMS's LCE line bays. Same with those still using GR303. We are in the process of migrating to SIP, but the C15/C20 will still handle TDM.

Re: SL2100 Transfer

04/24/24 12:03 PM
You need to look at program 24-09, sounds like it's not set for some or all extensions. The reason AA transferred your call to the user's mailbox on no answer is because of transfer recall, (AA being the extension transferring the call.)
There is no reason for anyone to wait for ring back to complete transferring calls. If there is a DSS key, while on the call press the DSS key and hang up. If no DSS key press the transfer key, dial extension, hang up. To transfer directly to the user voicemail, follow the same procedure but press 8 on the keypad afterwards and hang up, (8 has the letter V for voicemail)

Re: WE 118A Ring Generator Circuit and components
Greg Ercolano
04/20/24 06:13 PM
Following up on this thread, I did just now find a circa 1961 "Bell System Record" document that describes the circuit of a 107-b frequency generator that describes generating 20cps ringing from 115 VAC/60Hz. Skip to page 23 in this document: https://telecomarchive.s3.us-east-2.amazonaws.com/docs/bsp-archive/BLR/39-7.pdf..and find the article called "Static Frequency-Generators For Ringing Power". The term "static" in this context means "no moving parts", as would be the case with a motor-driving-a-generator approach to frequency shifting. This particular design appears to be a ferroresonant design (all passive components; transformers + caps) similar to the TelLabs 8101 schematic I posted earlier in this thread. There does seem to be a path of revisions that lead to the very compact 118a 30Hz frequency generator (aka. ring generator) we're used to seeing in 551a/b/c shoebox KSUs. The procession I'm familiar with so far is: 107b -> ??? -> 113a -> 117a -> 118a. The latter three were "potted" in a block of plastic, the 107b was (apparently) just a couple of large donut-like wound wires in a partially open metal case with a lot of exposed wiring, presumably to let one configure different frequencies, due to the numerous transformer taps available. In the potted units, the frequency is "fixed" and not adjustable. Here's pics of the various dedicated ring generators that I've been able to find so far; these pics from worthpoint's archive of previous ebay sales: 117a (30Hz): 113a (30Hz): 107b (20Hz): I have myself a 118a and a 117a, and I /think/ I might have a 113a (can't remember). I can't find much other info on the 107b, such as if it is indeed "configurable" for different frequency outputs.

Re: Looking for TIE KSU
Andyreed
04/18/24 06:37 PM
Well, so far I’ve gotten close. Kevin, C5Z, knows the whereabouts of a TCX-128 system. I guess you could call it the evolution of the 2260. He’s going to help coordinate that for me and I greatly appreciate it.
I found the power supply for the 2260 but no KSU so far. I’ve also found a TC-12 KSU (as far as I can tell it’s essentially a 1236 but uses 2 pairs?), but no power supply for it. It looks like it may be compatible with the 2260’s power supply but can’t tell for sure. Power specs in the manual aren’t detailed enough for me to tell.
So, still looking for an 820/1236/2260 if anyone runs across one. And in the meantime I look forward to getting the TCX-128 running.

Re: SV9100 and Baum's Act programming
newtecky
04/16/24 09:24 PM
I thought Baums law was to get the location i.e. room number Which would have to be done with a E911 Sip Trunk from what I understand
Lots of programming on both ends, the NEC and the provider
A lot of the hosted companies are throwing this into the mix and people don’t think twice. They just go with the hosted product if they have any money.
Seems like a ridiculous law to me. Everyone has a cell phone the NEC can tell you where the call was made.
Obviously, it would apply in certain circumstances RAY BAUM’s Act requires that all 911 calls must have a “dispatchable location” which means having information for emergency responders to find the exact location of a person who has dialed 911. In a standard office with a reception, I don't think there is much that needs to be done, expecially if the PBX notifies the reception about who dialed 911. In larger locations or some specific circumstances (as you mentioned) it would make sense to use multiple e911 numbers for specific location information. We had 2 offices that shared the same PRI. We worked with the carrier to send 2 different e911 numbers with the correct address depending on which building the extensions were located. Our company is doing nurse care facilites with phones in every rooms. With a hosted system we are now able to provide a DID to every internal extensions, and register every phone number with with a room number along with the physical address for 911. The nurses also get notified if someone dials 911, just like most on premisse PBXs already do as well. The main issue with cell phones is that there is no location information and I don't beleive that they are routed to a local 911 dispatch center. In a panic, people may not be able to rememeber the address of their current address. Also if the call gets cut off before they can tell the address to the dispatcher.

Re: Oddball modular connectors RJ45?

04/11/24 11:52 PM
If the information you found is from the typewriterdatabase, that is the information I recently shared. I thought it might be a standard alternate type connector rather than a "proprietary designed" which IBM seems to love so much. I can see why it would require the key. You wouldn't want someone plugging a 10 Base-T modular connector into the back of the IBM 85/95 Electronic Typewriter, or the 6731. Who knows what might happen.... Bzzzzzz *POOF!*

Things I didn't know about GRANDSTREAM!!
Carl Navarro
04/06/24 01:16 AM
I picked up some Grandstream material in the last week and my surprise began when I couldn't register the secondary stuff to my Cloud account. It appears that they addressed this issue last year. https://www.grandstream.com/online-marketplace-warranty-limitations-policy-pageOops. I suppose it's fair, but GS doesn't want any of the product that you can administer in the cloud to be purchased or resold on the secondary market. Meanwhile, I have a couple of gray systems and 10 or so phones of questionable heritage. :-( Time to figure out a workaround... Carl EDIT: After wailing and gnashing of teeth and texting Grandstream, I am now able to log into my cloud account and add this unit to my systems. The seller (Phillips Communications) on Ebay contacted who he bought it from and they released my new system back into the pool. Now it's mine. It's the first time they have had to deal with the 6300 series systems.

FYI...The network engineers ran Wireshark with call examples. The network engineers had me reboot both SV9100's and after that it works fine now. The network engineers said that when they installed their new equipment sometimes the MAC Address's do not release from the NEC equipment. Never seen that before.

IPO R11.1.3.1.0 DTMF Issue with J1xx phones
Toner
04/05/24 04:51 PM
Hi all, FYI and for our own reference we've found what appears to be a very specific DTMF bug with R11.1.3 and J1xx phones (it doesn't affect 9608 phones). Here's the rundown: A call that is placed which has an immediate shortcode match results in the IPO telling the J1xx phones to use RFC2833 for DTMF. In this example the phone uses it's redial button to place a call:

First, the IPO placed the call over the SIP trunk. It then sends an INVITE to the J1xx phone (I know, this seems backwards but it's how CCMS signaling seems to work)

You can see that RFC2833 is specified with the line "a=rtpmap:101 telephone-event/8000"Now a call to a 10 digit number where there is no specific shortcode match and we have to wait for the 4 second timeout:

This time the IPO starts with an INVITE to the J1xx phone but is missing the rFC2833 line and therefore we would expect Inband DTMF.

The IPO then places the call over the SIP trunk and specifies RFC2833. Shortly afterward, the J1xx responds with a 200 OK that does not contain the RFC2833 line. A capture of the RTP packets from the J1xx to the IPO proves the DTMF is missing in both methods - RFC2833 and Inband.

Do you have the 4.93 upgrade procedure document? You can use file control to upload the 5.03 file to the system.
A quick setup , really not.Every system is programmed depending on how a customer wants it to work. You can default the system to start from scratch.

Programming OfficeServ 7xxx to forward incoming calls
highlysecptial
03/31/24 02:37 PM
Sorry if this is a very naive question, but can anyone explain to me how to program the OfficeServ Device Manager (I have an OfficeServ 7100) to forward all incoming calls on specific incoming trunks to another external number? Ideally, I would also like to specify which trunk is used for the diverted calls.
Any help would be gratefully received.

Thank you for the suggestion. I was finally able to give that a try this evening. Unfortunately, I still get nothing from the handset. Is there a way to test the hand piece and the buttons? I'm assuming something using a multimeter with continuity tester? If I can troubleshoot my way through, hopefully I can find a way to get it working again.
