Monitoring ISDN Line

Hi,
Can any one guide me how to verify the status of ISDN link when it is configured as backup with dialer interface?
I have CISCO 3640 routers. I had configured E1 links as primary. ISDN lines are configured as backup lines.
ISDN line kicks in whenever serial line is down. Dialer interface is configured & binded to BRI interface in the router.
I would like to monitor/know the status of ISDN line automatically, now & then.
I know this is possible by non-intrusive manual testing.
I can not bring down the serial line to verify the status of ISDN.

hi
Quite sometime back we did face this kinda situation and we did overcome the same by dialing out the isdn line without distrubing the functional E1s.
if you have backup interface command or floating static route coded in your config the isdn state will be deactivated,if you can remove them off in off-peak hours it does comes active and u can check out the condition of ISDN lines.
And again i m not sure about any h/w boxes or automated commands to monitor the isdn line but peopl out here may be knowing more on the same line ofcourse their feedbacks would also help u out..

Audigy 4 Pro - Unable to monitor both Line-in 1 and 2 at the same t

I was under the impression when I bought this sound card with the external box that I would be able to monitor multiple line ins at the same time. I have a Korg TR-6 keyboard on the way and it will be here tomorrow, and?I just bought expensi've .25 inch cables to run from the L / R jacks of the keyboard along with the midi cables. Thus far using my .25 inch mic, I have been unable to get any signal from my Line-in 2 jack regardless, but what I've also found is there is no way for me to monitor both inputs at once.
Am I not able to monitor two inputs at the same time? Is the reason I cannot hear my mic when it's in line-2 because it's not a powered mic and relies on amplication? I'm really really concerned that I will only be able to do a mono-output, unless you have other suggestions?
Can I convert two .25 inch lines from my synth into SPDIF or anything? Please advise, I really have invested a lot of money into this already.

I've been trying to figure this out all night, still can't find anything even after tons of google searching. I'm worried I'm going to have to buy a midi / xlr interface to do the job right, even though this was advertised as a device perfect for musicians (we couldn't expect both a Left and Right input at the same time?).
If someone could please get back to me I'd really appreciate it.

HP Laserjet 4100 PCL 5E keeps "phoning home" and tying up our ISDN line

We have a couple of HP Laserjet 4100 printers that connect to the hospital via an ISDN line (can't upgrade at this time as that is all that is available at that location) and which we pay for by the minute (not much but still by the minute). The problem we are having is that the printer keeps "phoning home" about every 30 seconds or so unless we unplug them. The queue for them is located here at the hospital so I'll assume the printer is "phoning home" so that it can update the status in the queue and whether or not it is online/offline. We have other HP printers out in the field that don't have this problem and yes they do show offline in our queue they still work fine and have worked fine for over a year now.
My question is how does not stop the printer from constantly "phoning home" so that it can report its status. The current driver we are using the is the Laserjet 4100 PCL 5E. Thanks!

The product you have seems to be a commercial printer. For the best chance at finding a solution I would suggest posting in the forum for HP Business Support!

ISDN Backup without ISDN Line

Hello,
I have big problem. My client has to have ISDN back-up but there is no possibility to get ISDN line to my client location. Router has WIC 1B S/T and should call in to the another router with PRI interface when there is a problem with main line (FR).
How can I resolve this problem?? Where can I plug ISDN line?
Best regards,
Jarek

Hi Jarek,
If there is no ISDN service where the remote site is then you will have to forget about using ISDN backup from that particular site.
Your best way to get dial backup would be to use something like a WIC-1AM or WIC-2AM (analog modem WICs) at the remote site, connected to normal POTS phone lines. You would then need to install some digital modems into the router with the PRI (NM-6DM etc). In this way the analog modems can dial into the PRI, whereby the PRI router will direct the call internally to the digital modems.
This won't give as good a performance as a BRI ISDN circuit, but it will at least allow you to implement a dial backup solution.
Hope that helps.

I would like to known the cost of monitoring on-line system

I have a monitoring on-line system with the following features:
aquisition of 8 temperature channels and 6 vibration channels, storing data in databases,transmission on protocol TCP/IP, alarms etc...
But I do not known the cost of that systems in the market. I would like know which be the cost of a system like this?

There are specifics to your system features which will make the cost vary. One thing is, is this a system you want to build yourself or have developed for you by an Alliance Member. The costs of course being the time and resources and depending on the complexity of your application and in house resources you may be better served by an Alliance Member.
On your system cost from the standpoint of the hardware or software a number of factors may come into play. These include, your sampling rate requirements and accuracy requirement, if you have any special environmental needs (chambers, signal conditioning and so on).
On storing to databases, and using TCP/IP, and setting up alarms with pager or e-mail notifications these should be relatively inexpensive ... al
l depending on the specifics of your application (security, scalability).
Your best bet is to call an engineer at NI (http://www.ni.com/contact) that can get a clearer understanding of your needs and present you with different options.
Best of luck,

2 isdn lines on single bri

Is it possible to have two isdn lines(total 4B 2D channels) running on a single physical bri interface using dialer profile (or any possible method)?
I have seen cisco example which provide hub-and-spoke topology design but no indication whereby single bri on each end of the router supports multiple isdn.
Any help or advice will be deeply appreciated.

hi
its not possible to have 4B channels and 2D channels in a single physical isdn line,it does come with 2B and 1D channel.
i feel you are trying to pool 2 or 3 isdn lines under single dialer profile and want to use for some dialin/dialout purpose,thats very much possible in clubbing them like this.
But do throw some more lite about your requirement so that more inputs will be keyed in..
but still to startup with do find the link attached which speaks about different scenarios in the dial technology.

BT Infinity over ISDN lines?

Hi
I'm considering BT Infinity, but have a query regarding it's positioning.
The existing cable comes up from the ground by the front door, through the wall, then under the concrete hallway floor, and reappears on an internal wall - unfortunately in a wireless 'dead spot'.
I would prefer to be able to connect my desktop PC via Ethernet upstairs where I work, which obviously means moving the master socket.
However, at the point where the line enters (by the front door), there is a separate cable running around the outside of the house, which, many years ago, used to host an ISDN line. This is where I'd like the new master socket to be located.
My first question - would the ISDN cable be capable of hosting Infinity, or is the ISDN a different type of cable?
Secondly - if the cable is OK, would it be a trivial (free) job to switch the wiring over to the ex-ISDN cable, and use the old upstairs socket as the new master?
Many thanks
Mark

Hi mark,
AFAIK there's no difference between the wires that ISDN lines use and those that normal telephony/xDSL services use. The only thing with ISDN is that there is equipment installed on either end to ensure the signal remains digital (instead of digital/analogue/digital for xDSL). As long as this equipment has been removed (and there is no ISDN "Tag" on the line) you should be fine. If not, or if there is no active telephone service on the line (i.e. if you can't get a dial tone if you plug in a normal telephone) you'll need to address this first.
For your second query, it completely depends on what way you have your internal wiring configured. Some engineers who install Infinity are happy to move around pre-existing internal wiring however they are not obliged to do so, so if your internal wiring setup is quite complex they may refuse. You may be better to have this addressed before getting Infinity installed to make 100% sure everything is to your liking.
Hope this helps

QoS on isdn line

Hello,
I have an isdn line as a backup with the following policy
policy-map backup
class preced-5
priority 45
class preced-4
bandwidth remaining percent 30
class preced-3
bandwidth remaining percent 30
class preced-2
bandwidth remaining percent 20
class preced-1
bandwidth remaining percent 10
class class-default
bandwidth remaining percent 10
I can see drops at the critical class even when the offered rate is 1000 or 5000bps, while it should allow untill 45Kbps.
Virtual-Access1
Service-policy output: backup
Class-map: preced-5 (match-any)

(pkts matched/bytes matched) 268/189684

It should allow an /average/ of 45kbps. If your traffic is bursty you are going to see drops even though the 30 second offered rate is low.
If you are putting Voice into your LLQ make sure you are provisioning for the layer 3 header as well as the traffic. This will be about 80kbps for a standard G.711 call and 24kbps for a single G.729 call.
You may want to change the interface to
if#max-reserved-bandwidth 90
This shouldn't be affecting your problem, but it could eliminate any problems with the default-class percent versus the other non-priority classes.

How do I monitor the Line-In Sound?

I'm connecting my stereo receiver to the line-in sound jack. I know it works because I can record (and monitor) the sounds through Audacity. But,is there a way to listen to what's coming in without opening any app?
I think it's the same question as here: http://discussions.apple.com/thread.jspa?messageID=676560&#676560
and that didn't get an answer...
Thanks

You need some kind of application. The simplest is LineIn

Batch Monitor Command line Check Progress

Hey all,
i was wondering if there is a way to check progress of a file i sent to compressor using command line.
Thanks
Lars

ok so i found a pdf which tells me this:
Below is a synopsis of the command for monitoring batches. The Batch Monitor
command is located in /Applications/Utilities/Batch Monitor.app/Contents/MacOS.
Batch Monitor [-clustername <name>] [-clusterid <user name:password@IP address:port
number>] [-jobid <identifier> -batchid <identifier>] [-timeout <seconds>] [-query
<seconds>] [-help]
i tried putting that in but the result i get is Batch: garbled time
any ideas
Thanks

How do I monitor my 'line-in' recording with my Sound Blaster USB Mp3

I'm recording tracts of my band from a MD via line in. How do I monitor what's being recorded (in real time)?
Sound Blaster USB Mp3+
Thanks,
Mike

my problem seems similar to prior post.
I have attached Creative USB Sound Blaser MP3+ a.k.a. SB0270 to a Compaq Presario 700 lap top computer via its USB .0 port. I'm running WinXP Home with SR-2 update.
I have found that I CAN record audio using Creative's Wave Studio by first selecting "Line-In" in Microsoft's "Volume Control" software Options/Properties/Recording. "Line-In" then appears as the label on the record level control in Creative's Wave Studio. This was not the intuiti've choice as music fed in through a USB port supposedly uses the SPDIF (Sony Phillips Digital Interface Format). Selecting the SPDIF in Microsoft's "volume control" doesn't work.
However, although I can record the audio, I can not find any way to monitor the level of the audio while recording. When recording using Creative's Wave Studio, an indicator (lower left of screen) shows it is in the recording mode, but the level indicator is a straight line at zero / baseline. Furthermore, the input signal can not of been too small to be seen, because the graph shows nearly full modulation on playback.
How does one monitor the recording level while recording?

Monitoring the Line-In port

I am new to Mac, so please excuse if this question seems too simple. I want to be able to hear the audio coming into my iMac G5 through the line-in connector. I can see the line-in audio levels change in System Preferences, but there is no sound on either the internal speakers or external speakers connected through the Audio-Out port. I've checked all the volume settings, mute check boxes, etc. that I can find. Other sound seems to be working fine (iTunes, CDs, iMovie). This is a simple task in Windows so I figure it is even easier on a Mac - but I am stumped. Can anyone help me out?

I think you need to listen to the source through an audio program such as GarageBand while you are setting the levels - kind of makes sense as you will then be setting the right level for the particular application.
[If using GarageBand remember to turn the Monitor to On to hear your input when creating a new Real Instrument track].

Hp 2711x Monitor horizontal line across screen

Monitor HP 2711x has a horizontal line about 2/3 the way down, completely across the screen about 1 pixel wide. The line looks like a slice trough the current screen image to some kind of image behind the current open windows, but there is no such image behind. Adjusting the screen resolution turns the screen black monentarily which sets the line's color to black when the screen reappears, but then the line changes to again look like a slice through the current window to some kind of false window behind. Rotating the screen image does not rotate the line. Adjusting the screen reolution does not alter the line. Resetting the monitor to factory default does not alter the line. Changing the PC providing input to the screen does not change the line.
Latest HP driver is installed. Monitor's serial number:[Personal Information Removed]. Any suggested fix, please? Thank you.

Monitoring ISDN D channel behaviour

I'd like to monitor an unstable ISDN D channel. Can anyone suggest a good way of generating syslog messages whenever the D channel fails?

Hello Paul,
not sure if this helps you, but there is an ISDN MIB which includes D-Channel monitoring, check this link:

New DID's Numbers change on E1 ISDN lines

Dear support,
As I have Two ISDN E1's lines one on each voice Gateway CISCO3925 and CUCM 7.x
From Telco current DID numbers example :24634 XXX now the Client want to change to new DID i.e 27868 XXX
Phase I : only incoming with new DID Number . Outgoing must be go with old DID number only .
Phase II : Inbound / out bound call must be use with new DID only.
So please advice what would be the action plan configuration need to done on voice gateway and Call manger .
With Regards
Syed

The basics would be to create a new dial peer for the new number block.
If you are still using the same provider there will not be much that needs to change as long as the extension (subscriber) block remains consistent with the new number range.
ie your dial peers might look like:
dial-peer voice 100 voip
destination-pattern 334455.... !old example pattern
session target ipv4:10.1.1.1
dial-peer voice 200 voip
destination-pattern 445566.... !new example pattern
session target ipv4:10.1.1.1
obviously this is rather simplified and I am not aware of your current configuration, but the idea is that you can feasibly run both dial-peers and as the calls come in you can process them accordingly
