tn744 vs. IP Media Processor 3

[mentallimit]

We are having alot of trouble with picking up the phone and not getting dial tone. Also talking to someone and hitting transfer only to hear dead air.

I have three IP Media Processor's in my system (8700)already and 0 tn744's. Just wondering if I need to add another IP Media Processor or should I add a couple of the tn744's? I also have a remote site with 4 g700's.

Just looking for some suggestions here...

mentallimit,

run "list measurements tone-receiver summary yesterday-peak" command and take a look at "total queued" and "total denied" columns for "CC-TTR" row. if there's anything but zeros, you need tn744.
run "list measurements ip dsp-resource summary yesterday-peak" command and watch for "denied peg" and "% blk" columns for every network region. again, if anything but zeros, you need additional medpro.
like that.

 

[mentallimit]

What is the difference between the two? Because I don't have any tn744's on the system. Does the Definity come with built in CC-TTR ability?

 

[nohuhu]

mentallimit,

tn744 provides tone receiver ports for a port network. when you pick up a handset, system allocates a tone receiver port for you, provides dial tone and waits for the digits. if there are no available tone receiver ports, you will get "dead air" instead of a dial tone. it's true for all kinds of phone types, but ip phones are more complicated because they need not only tone receiver ports but also free medpro channel to packetize that dial tone and send it to the phone.
definity does come with cc-ttr ability but it's not "built in", it's always provided by one or other kind of circuit pack. in older definity servers (csi, si, r) it was tn2182 board that gave 8 tone receiver ports. in newer systems, an ipsi board provides the same 8 tone receiver ports for an epn. however, since neither definity server couldn't be sold without tn2182 nor newer s-based systems can't be sold without ipsi board, you may consider this ability as "built-in". but technically speaking that's not correct.
as for g700/g350/g250/g150 media gateways, all of them indeed have built-in tone receiver ports and that's a fixed configuration. you can't add more cc-ttr ports to a g700. nor adding another g700 would help because every g700/g350/g250/g150 is a separate "port network" of a kind, they're not sharing resources between them. i.e. if you lack cc-ttr in your main epn you should add tn744 there not try to add another g700, it wouldn't help.

 

[mentallimit]

Ok, I think I am starting to understand. But my question now is since I do not have any tn744's...how am I getting dial tone? From the IP media processers?

Thanks for walking me thru this...it is truely dizzing.

 

[nohuhu]

mentallimit,

no it's not dizzing if you get the point. as i said, all of your port networks (with tn type boards) either have a tn2182 or tn2312 circuit pack, it's mandatory. run "list conf all" and you'll see. g700/g350/g250/g150 media gateways have that capability on board but tn-type cabinets must have a circuit pack that provides dial tone and tone receiver ports, it's always there. now, you don't ever need to expand dial tone providing capability because it's shared by default, i mean that if you pick up a handset on all phones in a port network they all will be connected to the same single dial tone port. this connection method is called "barge-in". but you would need a dedicated tone receiver port for every phone because this port will listen to dialed digits and respond accordingly. got it? now, this situation is hypotethical, in real life nobody would pick up a handset on all phones simultaneously, so the real demand for tone receiver ports is not so high, in many situations it's enough to have 8 ports on tn2182 or tn2312 circuit pack. however if your port network is serving people who call a lot or, for example, you have some vector processing with collecting digits on a trunk in this PN, you may run out of tone receiver ports in this PN. add a tn744 and you'll be fine.
but firstly run "list measurements tone-receiver summary yesterday-peak", or "today-peak" for all that matters, to really see whether you need additional cc-ttr ports or not.

 

[mentallimit]

dwalin, again thanks for all the speedy posts to my questions.

But I did do a "list config all" and I DO NOT have ANY tn2182 or tn2312. Hope I am not driving you insane.

 

[nohuhu]

mentallimit,

no you will not drive me insane, not having tn2182 nor tn2312 would only mean that you don't have tn-type port network, is all. however if you post "list conf all" here i'll be able to help you faster.

mentallimit,

judging from this configuration you either have si with scc cabinets or, more probably, ill-configured s8500/s8700 with old scc cabinets. could you please show me "list conf all" command output?
and showing "list measurements tone-receiver summary yesterday-peak" output wouldn't hurt either.

 

[mentallimit]

Didn't I just post the "list conf all" ?

mentallimit,

oops sorry, i meant "list conf soft" command. and you see, indeed there were queued cc-ttr and dtmf requests, there are 8 ports in the system now and peak number of requested ports was 9, hence queued requests. you definitely need at least one additional tn744 circuit pack.

mentallimit,

just like i said, you have r12 s8500 or s8700 upgraded from older definity. i can't say now why tn2312 ipsi board is not shown in "list conf all" output but it's definitely there otherwise your system wouldn't work. if you go to the system and take a look at "a" cabinet you'll see that circuit pack.
and if you take a look at "disp sys cust" screen page one, there's a "platform" field there that may tell you what exact system you're running, s8500 or s8700. afair s8500 is 5 and s8700 is 6.

The "list con con" or list configuration control will show the IPSI's.

I just found out (the hard way) that in an IP connected configuration the system will not use tone detectors or call classifiers in another port network. This is a complete reversal of the fiber or direct connect port networks. Each IPSI has 8 resources on it. I would add refurbished TN744 Call Classifiers - they're pretty cheap.

I am going to order a vouple of the tn744's anyone have some documentation on installing them? Are tehy hot swappable?

 

[nohuhu]

mentallimit,

these boards are hot swappable and no, there is no documentation on installing them, because there's no configuration related to this board. just plug it in and if it's working it will add its capacity to etr-pt available to the port network.

 

[mentallimit]

Thanks again dwalin! So looking at my output from yesterday, with all those DTMF denials it's a good idea for the tn744's? How many do you think? 3 more?

 

[nohuhu]

mentallimit,

judging from your list measurements output the peak requirement was 48 ports. you only have 8 so you need 40 ports more, that's 5 tn744 boards not 3. i myself would throw in an extra one just to be sure.
