RE: CAS and CCS - out-of-band and in-band [7:66607]
Yah Eric you mentioned almost all of them rightly, but I would like to specify the T1 and E1 part a bit First thing T1 uses some bits of each timeslot (6th,12th,18th and 24th bit of every timeslot and these bits are also known as A,B,C and D bits) and since these bits are part of the timeslot only, a CAS T1 would be a true In-band signaling circuit. On to E1s, they can be used in both the flavors, but confusion mostly arises for CAS E1. A CAS E1 though uses A,B,C and D bits but all these bits are sent in the 16th timeslot, so as per my understanding a CAS E1 should be termed as out-band signaling circuit. Please correct me if I am wrong on this.

People and books will tell you contradicting things. For the right definitions you can best refer to ITU or ANSI specs. I haven't been involved in classical telecoms for years, but this is my interpretation: With in-band signalling the signalling is conveyed on the same channel (timeslot, connection, ...) as the voice or data is carried. So for example pressing digits during a phone call can be considered as in-band signalling (DTMF signals). Fax and modem calls may also be considered in-band. Early phone systems also used signalling systems like R2 to control the call (specific frequencies were used to control the call). Out-of-band systems either used specific wires or specific frequencies that were out of the normal frequency band. I can't remember exactly, I have some coursebooks somewhere, but I can't find them right now. Anyway, as far as I know in-band and out-of-band originate from the old analog telecoms world, and may be ambiguous when applied to the digital world. Nowadays, if you really want to classify digital signalling is in-band or out-of-band, I would say the following: out-of band signalling is signalling that is transported over a different channel (timeslot, connection, ...) than the data or voice. So for example: - ISDN BRI and PRI both have a dedicated signalling channel (the D-channel), so it's out-of-band. - In the European PSTN and GSM networks there are dedicated signalling links for voice trunks. The call setup is controlled by common signalling channels, hence the name common channel signalling. Signalling system number 7 (SS7), also called common channel signalling system number 7 (CCS7) is an out-of-band signalling system, since the signalling is not conveyed in the same channel as the voice (or data). Note that the signalling channels can be implemented in different ways: the signalling channel can be part of the same E1 trunk (for instance timeslot 16 or any other timeslot except 0 !!!) that carries the voice, this is called associated signalling; the signalling channel can also be in a timeslot of an E1 different to the E1 that carries the voice. The latter is called quasi-associated signalling: there are dedicated redundant signalling links that do not follow the same path as the voice trunks, only the begin- and end-points of the voice and signalling paths are the same...confusing, isn't it? ISDN BRI and PRI use the same concept as SS7: multiple voice or data calls are controlled by one signalling channel, which makes them common channel signalling and out-of-band. Channel-associated signaling is very confusing to me. $%^*!* where are those course books??? Hmm, let's use this definition from Cisco: "...Channel associated signaling: The transmission of signaling information within the voice channel" So that seems to imply that all in-band signalling is also CAS signalling, which makes sense to me. So what about X.25? Initial call setup and data follow the same path: so CAS. Would you classify it is in-band??? So what about E1s and T1?? You can't just classify a standalone E1 as one or the other. In my opinion it depends on the application, the signalling system and the scope of reference. When you make a call to certain international locations, you may still hear some old signalling along the path, caused by inband CAS systems. A channelized E1 that carries voice or data calls is normally controlled by a common channel signalling system. However, maybe I shouldn't mention this, since it is too confusing: an E1 can also be classified as CAS, when you allocate a 2kbps signalling channel to each 64kbps channel32*2 = 64 kbps, isn't it? And what about timeslot 0, it's always present and it is used to convey information...we should classify this as CAS, shouldn't we? You see very confusing.

RE: number of CCIE [7:70151]
Hi All, I was stopping myself for writing on this thread for quite some time. Quite a number of people have reverted back on this, but this one, (from Peter) is just kind of PERFECT. Priscilla also wrote on one of other threads, that for having a worthwhile career you just don't need good networking skills, but also "good networking of people". And I am sure it works. I have seen quite some useful mails from NRF, but this one is a losing battle (NRF: don't mind friend, nothing personal) and what Peter has stated is perfectly right (of course as per me) So a CCIE number, does matter, but more so, since all the chances are that the lower number ones would be having more experience and better "networking of people". And the higher numbered ones would be, in all chances, relatively new and also still into the stage of building their "networking of people". Just my 2 cents :) Vikram -Original Message- From: Peter van Oene [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 17, 2003 3:21 AM To: [EMAIL PROTECTED] Subject: RE: number of CCIE [7:70151] > > > > [JN] Yeah, but does the "college happy" HR dude (your idol) who > > says > > "bachelors required" on dinky IT jobs (e.g. desktop support > > tech) pay > > attention to that?

I don't mean to get into the battle of which CCIE number is better than which as I don't really have an opinion. However, one thing I do pick up on is the reliance here upon getting through HR screens. I don't recall ever getting a job through conventional means myself and I don't imagine that many somewhat established folks who do better than average work do either. Most of the hiring I've ever participated in was referral based as well. To me, this debate really only applies to those folks who do not have contacts in a given area and who are not prone to more aggressive employment acquisition strategies. This bunch of folks tends to flood resumes out to Monster and hope they get a call. However, I would see this category of folks as pretty junior, in which case I wouldn't expect to see them applying for the top tier jobs in the industry. These folks need to get a job, get established, and then leverage their contact base to move on to bigger and better things, or leverage their track record to move up internally. So, the way I see it, either you are pretty new to the industry and need some help getting through screener bots, or you are not and should find far better mileage leveraging your contact base in the industry. If you are good at what you do, likely the folks you worked with noticed this as did the vendors who worked with you as did your customers. Somewhere in that mix there has to be a hotter lead than www.findmeajobfor100k.com. If you are new, having a CCIE number of any type likely helps a bunch and I can't see anyone caring how high or low it is unless you are trying to get some uber job. If you are, you'll likely lose to someone else who came recommended and the how many guys passed the lab before you won't be of much significance. (did I just get into the debate I said I wanted to avoid? :) Anyway, I guess I'm not sure who the group of people are who are highly talented, yet have no contacts in the industry but still expect to pull down top calibre jobs. I'm also not sure who the top calibre job employers are that would chose not to hire you based upon how high your CCIE number was vs how well you fit the job and interviewed, but I'm assuming this CCIE number value cut deals more with first cut resume screening.

RE: number of CCIE [7:70151]
OK... My dear friend, NRF, over here is fired up and ready to go on anyone, who responds on this thread. :) Nothing personal, but you did mentioned, or rather gave a lot of stress on maintaining crime-less life (I am not able to understand the reason for the same, did I mentioned that I was advocating criminals, or are higher number CCIEs are? not sure) then, you mentioned that knowing English is necessary or prudent for finding a job in US. Well (though I know English reasonably well, but) I will like to ask you one thing, do one has IT jobs in US only?, I am located in India, so does that means that there is a complete lack of Networking or IT jobs in India..? Coming back to the main thread, (though people do deviate from the main threads and wander around, and my response was totally focused on Peter's response), I am not a CCIE, yet, but whenever I get this number for me, be it 12000 or 2, I will not trade it for any lower number. It will be MY number, and I will not like to part with it. And, while we are discussing the importance or value of the CCIE program, why was it the case that we had to start this number trading exercise? Just my Rs. 0.02.

In fact, I have engaged in many newsgroup-post-wars where I have stated precisely that. Go reference some of my many posts on this newsgroup or on alt.certification.cisco on this very subject. However to talk about this subject is really to raise an issue that, for purposes of this discussion, is neither here nor there. The issue at hand is has the value of the CCIE declined over time, and the preponderance of the evidence seems to be that the answer is 'yes', given the fact that everybody, including myself, would like to trade their CCIE number for a lower one. Nor is the gambit that this has to do with the connection between a lower number and more experience have much, if anything, to do with it. I would ask even the lower-number and highly experienced CCIE's would they be neutral to trading their number for a higher one. I'm not asking them to think about trading their experience, just their number. If the CCIE hasn't declined, then they shouldn't care what number they are. But of course we all realize that they DO care, and care deeply. Raising other issues that have to do with employment is not really relevant in this thread. After all, if we wanted to go down that road, then why don't we raise ALL the issues that affect employment? I would say that certain other things are even more important than the people-networking in terms of finding work. For example, a criminal background. I don't care if you're the most brilliant engineer in the world, you're CCIE #1026, and you're on a first name basis with John Chambers - if you're a convicted serial-killer, you're going to have difficulty in finding work. Let's face it - no company is ever going to hire Charles Manson. We could talk about personal lifestyle choices. If you're a coke fiend, finding a job might not be easy for you. If you can't speak the language of the country in which you're trying to find a job, you will have great difficulty no matter how wonderful your other credentials you are. For example, surely you would agree that if you want to get a job as a network guy in the USA, this might be difficult if you can't speak English. But should we really be talking about those kinds of things? I don't think so, for they are not relevant to the discussion. The auspices of this discussion are necessarily narrow - basically what has happened to the value of the CCIE

RE: Multimedia/Voice over VSAT [7:71706]
Hi All, Well, we all know that due to technology advancements, today the IPLCs (or read leased line circuits) are a lot cheaper so there is not real need to transport voice or video on Satellite links, but then the satellite links do have much more uptime guaranties, so enterprises do consider satellite for backup options. Now I have seen many implementations of voice on satellite media, and if you can do away with the basic apprehensions about time delay, voice quality is just fine on satellite too. I mean you can manually inject a satellite kind of delay (550+ msecs) on any end-to-end fiber implementations and the voice quality will be more or less same.

RE: Query on MGX8850 [7:71702]
Hi Diva,
I feel I need some more information on this..
1. Are all 4 nodes part of the same network, i.e., are the India and UK end
nodes back connected?
2. Are they having just 1 IPLC each?
3. If they are having more than 1 IPLC, are you running PNNI or some other
routing protocol on them, or have you done some static mapping?
4. Do you mean to say that you have 2 routers running HSRP and they are
attached to different FRSMs on FR? And then on in case of one IPLC going
down you want the traffic to route through the other IPLC?
On the last point, as per me it would be better to connect your MGX nodes to
each other locally at both the locations and then by running PNNI end-to-end
you can route your traffic in case of IPLC failures, and more so if both the
nodes are sitting close by. For your traffic routing you can rely upon on
some IP routing features.

I have two MGX8850s in India on to which one IPLC each are getting
connected to the PXm1-e1 card.The other end of the IPLC s are connected
similarly to two MGX8850s in UK.
We have a FRSM card on each of the MGXs .We have 4 cisco 3745 routers
connected using a pair of DTE and DCE cables.
The serial interface is configured for framerelay.I have not created any
subinterfaces on the serial interface for framelrelay. The routers are
configured with HSRP. I would like the HSRP to track the changes in the
status of the IPLC and switch over the HSRP active router. Right now, when
the IPLc goes down, the FRSM card still shows up and the router serial
interfaces shows line protocol up.Thus HSRP , which is tracking the serial
interface still assumes that the link is up and hence will not change the
state.
My objective is :---
The serial interface connected to the FRSM on the MGX should be able to
know when the IPLC connected to PXM1-e1 goes down.And the HSRp which is
tracking the serial interface should change the state .

RE: ATM Bandwith [7:71937]
Hi Gerard, ATM as a technology per se, is a high overhead technology. As the basic fact the fixed size cell is of 53 bytes and out of it the Cell Header consumes 5 bytes. So the net payload per cell is actually 48 bytes only, so effectively you are having a close to 10% overhead, and it is not the end, you have to leave some bandwidth on the error detection etc things also, because of which you are never able to use more than a tentative 90% bandwidth on any kind of technology. So if you are getting a burst of 30 Mbps on a E3 link, (I would like to know about the bandwidth consumption tool or parameters used by you) you are not doing bad; for sure.

Hi Ismail, I am not very comfortable with the equation you have provided. But for your questions, we are talking about 8 as all the bandwidth calculations are done in Kbps/Mbps etc. and it would be Kilo Bits Per second, not Kilo Bytes Per Second, so you need to convert Bytes or Octet values to Bits values. Secondly, you will be dividing (if that equation is somehow usable) by 10,000,000 because 10Mbps is equal to 10,000,000 bits per second only.

Hi Rayan, Double check on the 3640 interface configuration, you must be having a manual configuration of bandwidth 128 on it. The 7200 is acting up as the Cisco default for serial interfaces.

No, I won't think that these mails are sent by some person. I have a rule on my outlook application which sends all mails addressed to [EMAIL PROTECTED] to a specific folder, but this one is directly coming to my Inbox, so I feel that it will be a Server or mailing application (Majordomo I believe) bug, which is sending personally addressed blank mails to some or all the list members.

RE: Port Spanning (Monitoring) [7:73320]
Hi stevo, I am assuming that the router's working ethernet interface would be connected to some interface on a switch, so won't it be a better idea to monitor that switch port, rather than trying to monitor router interface.

RE: ATM PVCs Switching on Router 7200 [7:74094]
Hi Mohammad, You can not really switch an ATM PVC on a router, you need to have a switch (popularly called WAN Switch) for that. But even then, if you have 2 ATM PVCs facing different sides, you can exchange traffic between them, by IP routing. e.g. you have one PVC configured on interface atm 1/0 with IP 10.10.1.1/30 and another interface atm 1/1 with IP 10.10.2.1/30. Now both these interfaces will be talking to their respective counterparts on the other side, but on the router you can simply configure adequate IP routing and the router will get ATM cells from atm 1/0, convert them to IP packets, hand them to in IP shape to atm 1/1, which will again convert the IP packets to ATM cells and those cells will be sent out to remote location. Please revert in case more information is required.
