    Deleting a PRI from a 3 PRI TRK Grp

    Sorry but I can't answer your specific question as I am not familiar with your system.. But before you do anything I would suggest learning as much as you can about these PRIs. 1) Does each PRI have it's own D channel (e.g. 23B+D) or does one have the D channel for all three (e.g. 23+D, 24B, and...

    Cisco IP Phone 7841 8851 unable to forward to external number

    This is deliberately made impossible or hard because of protecting against toll fraud. Good luck, I am not saying it is impossible, just that the default doesn't surprise me.

    Inbound trunk no disconnect

    Is this a loop start trunk? Is ground start a possibility? If so that’s the best case solution. If not, and if you have been in telephony for a while, you know this, disconnect signaling is problematic. Best answer on loop start is a loop current wink, called CPC (calling party control). After...

    Avaya IVR Call Transfer to External number Using Blind Tranfer.

    My educated guess is that it cannot be done on the majority of systems. The exceptions would be systems entirely created by non-phone savvy engineers (IT folks without background in telephone switching). Keep in mind that in many ways Calling Line ID (AKA caller ID) is a logical extension of...

    Outbound dialing issue

    You are looking from something called enbloc (from enbloque) dialing.

    Phone system bugged?

    Bugs on analog lines can *sometimes* be detected. Bugs on digital lines are impossible to detect. The FISA court that was created just to deal with this this type of scenario has been bypasses for "security" reasons despite the fact the court, records, and judges are all secret. Even optical...

    Maximum distance from ISDN 30 - Switch

    I am in the USA so I don't know off the top of my head. But it will be exactly the same distance as for an E1 since the ISDN-30 is CEPT E1 at Layer 1. DO your searching with CEPT E1 instead of ISDN and I expect you will find something fairly easily. However, to get back to your problem. You...

    Network Certification

    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...

    ISDN AMI NT1 and line cards!!

    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'm LOST when it comes to ISDN's

    Well, I am not an expert from the switch end of things, but I can answer some of your questions. One DSL per subscriber. Each DSL can, at least in theory, support up to 8 terminals. Not sure how this correlates exactly to TSPs, and most switches do not support 8 terminals. In reality, in the...

    There is also a 2500 version of this. It doesn't have a Touch Tone keypad ;) ------------------------------------------- TIP: If you ask a better question, you will get a better reply. Be specific so we can help!

    GFI Outlet

    The "interpetation" of the code (and the code is local, but may, and often does, include the National Electric Code (NEC)) is completely up to the "authority having jurisdiction" namely the inspector. You may be able to get a second inspector to give an opinion, but odds are s/he will not want...

    How can i stop radio signal from bleeding into my paging?

    Read the stuff on the Sandman site. Determine if the station is AM or FM (they will give a station ID near the top of the hour. Determine if the problem is on the input side or the output side (disconnect the input from the paging amp and see if you still here it). If it is on the input side...

    splicing CAT 5

    IIRC 110 blocks are Cat.5e rates. I know that 66 blocks are not. As far as splitting out pairs, I don't see the relevance to this thread. ? ------------------------------------------- TIP: If you ask a better question, you will get a better reply. Be specific so we can help!

    verifone cc machine won't break dial tone

    Here is my off the cuff guess The terminal has relatively short DTMF tones. Quite possibly they are within spec, but the knology device may not be built on the standard (most people engineering this stuff these days are pretty ignorant). Or you may find the duration is illegally short on the...

    CLI handling by EWSD exchanges

    Building a T1 Emulator

    Guys, s/he already said s/he wants to test including the signaling. So Telnettech, what kind of signaling will you be using? I know of nothing that can act like a min-PBX for a robbed bit T1. If we are actually talking about a PRI, the Aurora PRI and Aurora Duet can both act like a mini PBX...

    splicing CAT 5

    Mounatain bear is nearly correct. There is one better option. Ideally you want to use 110 blocks to make the "splice" just as you would where Horizontal meets Vertical elements. Next comes the plugs and through adaptor (all Cat5e of course and Lastly a connector block with patch cables...

    ISDN 10 SETS

    Each line will have different requirements for the phones, depending on how smart the phones are. You may very well NOT be able to switch phones around. Settings that may need to be set on each phone are ISDN Type/Switch type: (5ESS Custom, DMS Custom, NI1, or NI1) SPID1 SPID2 Do you have...

    ISDN Monitoring Box

    If you use a protocol analyzer you will get a cause code when a line is disconnected. But you would need to search through the raw data. Some protocol analyzers will tell you if Layer 1 is dropped, but again it would be up to you to analyze the captured data. What exactly are you trying to do...
