Hello Folks, Not a lot of activity on this board. I am a weird case. I have a lifelong interest in Telephony and have taught myself a lot. I also have an audio background as well, having been involved in radio. I was very lucky to have had a job that used both these skillsets with a company...

thread589-1638617 Wow, AMI U interface! That is some early ISDN equipment! You do realize you could use 2B1Q instead and it won't mater in the user-side of the NT1, yes. ------------------------------------------- TIP: If you ask a better question, you will get a better reply. Be specific so...

I need information on, or a source for (part number) for the adapter cable that goes from their proprietary D connector to winchester female. If I can't find this, I would settle for the adapter cable to X.21 DB-15 This is for a Tellabs Martis DXX STU-160 modem I will keep on looking through...

Hi, I am working on the small office Office Point system. It is not a HiCom Office Point. I have the manual and am trying top program this, but I am running into problems. I keep finding settings from the previous owner. I have worked on these before and am pretty sure the problems I am...

This is for the little 1-line cobotyx auto attendant. The manual came unbound and I have lost part not exactly sure how much) of it. I am putting this unit back in Service and while I did put most of the manual in a safe place not all of it! I'd prefer to have the whole thing and am willing to...

Hey folks. I am familiar with the basics of AMI and AMI with Zero Substitution. I am being told by a vendor it is OK to run B8ZS on a T1 configured for AMI. This makes sense since the end user equipment would should handle this on both ends. However, if this is the case it seems very odd that...

Here is a link to an interesting 5-page article from Telephony?s online magazine titled ?The best phone company in America?? http://telephonyonline.com/mag/telecom_best_phone_company/ Interesting because it doesn?'t bestow the honor to a traditional Incumbent Local Exchange Carrier. I have...

A customer has a specialized Broadcast Telephone system they wish to connect to the Opt 11. This system is primarily intended to connect to a CO switch. The system is working fine with the CO PRI. However there have been integration issues with the Nortel. It supports PRI and T1 robbed bit E&M...

I notice the name of this forum changed from "General Telephone" to "General Converged Phone Network". Hmm, personally I would say these are different topics. For example under the old forum questions about brand X PBX were appropriate if there was no forum for brand X. Also discussion of...

Those familiar with this system know the system uses four pairs in a USOC configuration. Pairs 1 to 3 are tip/ring. The fourth pair carries DC to power the phones and is also used for Intercom, Paging and various signalling functions. I have been installing a used system and had no power...

OK folks, I know for a fact that a 6-position plug (such as the "RJ11") can plug in to 8-position miniatur emodular jacks (such as the "RJ45" and work just fine. And this scenario is very conveninet in structure writing scenarios. What I would like to understand is if this is a legit...

I picked up a used 745 recently. It only powers up when connected to 12 volts and in charging mode. My guess is the battery is totally dead. Does anyone have a service manual for this? Does anyone know the battery type/specs (I'd like to find out how much a generic replacement will be before...

Hey folks, Does anyone have first hand experience interfacing to the station side ISDN BRI ports using either the USA National ISDN-1 or National ISDN-2 protocols? I've never run across problems with HiCom, but it appears Siemens may have reinvented the wheel with HiPath, and in the process...

OK folks. This is the kind of question normally I'd be answering. But in this case I'd like a second opinion. I have a major client who is trying to interface a piece of our gear (called "Xst" in the logs) to a HiPath switch. The Siemens folks did some log captures and it sure looks to me that...

The DMS by default supports service messages on NI-2 PRIs. Many CPEs do not support serivce messages. Under these circumstances weird situations were inbound and/or outbound calls are not possible despite the fact not all trunks are full. It is possible to turn of the service messages to...

Just got a deal on a few punch blocks. They are Siemons S66M blocks with the wall mounts and covers, but there is also a circuit board with a bunch of compenents. The Keptel sticker says Keptel Smart Block; 4 Wire; 9541; 90631. The punch block is labelled T1 R1 T R T2 R2 T R .... T12 R12 T R...

Hello, Do 150e analog trunks support caller ID? I know that caller ID is support on ISDN trunks and is displayed on the caller list on the set. However as far as I can tell it is not supported on anallog trunks. If so are there third party solutions or workarounds? Thanks
