Creating Analog "trunks" 1

[chrish2600]

Hey guys, just a quick question if what I want to do is feasible:

I have an option 61c at my property and in an effort to cut down on T-1 costs and long distance I was curious if there was a way that I could create the following..

Create a new access code (i.e. 8) that when used it select from a group of analog TNs I have available to dial out. So say I have 4-1-2-0 through 4-1-2-15 that are on an analog card, have the nortel setup to hunt that group to dial out.

So basically I hit 8,14045551212 it looks for an available analog line to jump off of gets a dialtone from one of these lines and passes the call off.

My questions are:

1. Is it possible to use normal analog TNs to pass calls out of, since they are normally set up for station devices and not CO. (Can you make these TNs set so that they are ready to receive a dialtone and not generate one?)

2. Can the nortel Option 61 be configured to use a standard set of TNs to trunk calls out? Or do you need a special card?

I know what I'm doing sounds kinda ghetto, but I am going to be passing the calls off to an Asterisk PBX to trunk the call over SIP. Unfortunately this is the cheapest way I've found to keep both systems up and running during a transition phase. So don't laugh =)

I "think" what you would need is pots lines going out a universal trunk card. Those tn's would have to be built as cot (central office trunks). Chances are though that you will still get a better rate on your T than going the analog option. Epecially since pots line are around 40 to 60 bucks per line. That T more than likely handles a chunck of all outbound and probably inbound traffic depending on how busy your sites are. If the actual cost of the T is the issue, maybe you should consider taking bids from alternate carriers at a better rate. That is of course going under the assumption that you are not locked into a contract with you current provider

When you use the word Analog, I'm not sure if your talking about an Analog Trunk Card or an Analog station Card. And how are you connecting the 2 systems, Are they next to each other, across town or across the country. are you going to use leased lines, dry pairs or Fiber?

 

[chrish2600]

Well I have analog station cards right now, I was wondering if they can be used as analog trunk cards. My other pbx is in the next room over, I'd just be running a 25-pair cable to a patch panel in the other room.

Pbxn: I'm just wanting to patch the lines to another PBX. Calls wouldn't be leaving the building as far as the nortel is concerned.

I have used LOP start trunk cards between 2 PBX's and programmed them a LDR.This was back in 1985.

Well, I had to go to the bathroom and sit and think about this one. I will refer to the Nortel as switch A and the
Watchamacallit B(sorry never heard of it) If you have
analog trunk cards on switch B that can be configured as
DISA and pass dial tone to switch A then you can just
crossconnect port for port across the tie cable and tell
user on switch A that when they dial "8" they will hear ringback then a second dialtone then dial the destination
# with an acess code(9 orwhatever). The better way would
be if you have analog station ports on switch B tied to analog trunk ports on switch A(loop start) and have the
acess code for that trunk route "8" getting dial tone from
switch B and then dialing or use Bars and route long distance calls by using your AC1 to that trunk route.

Sorry for such a long winded answer
Good luck

Inform - Exactly! I was going to have station ports generating a dialtone from switch B and have switch A's ports "listen" for a dialtone.

Can I somehow configure the analog station ports on my Nortel to just get its dialtone from switch B?

What would happen if both are generating a dialtone?

you need a nt8d14 for an analog trunk.. one card, eight trunks. you don't need to use ac2 for that dialing plan. in fact you almost never need anything more then a single ac code..

after you dial nine, your switch can look at every vacant trunk in the switch and pick depending on both the station ncos/tgar and your ld 86 entries.. look close at price, pri's are way cheaper per trunk then analog trunks in every place i've heard from... 10 analog trunks price out at the same price here as a 23 channnel pri

John,

Keep in mind that I'm not actually going out a POTS line. It's going over to an analog card into another PBX to send the call out over the internet.

I just want the Nortel to THINK its a POTS line.

 

[johnpoole]

then all you need to do is call the analog station.. if you want to route to an analog station after dialing 9, then you need to make those analog staions, two way analog trunks by using a analog trunk card.. i've done that when using analog stations from my switch as inbound to a key system...

when you dial 9 (ac1) that takes you to ld 90.. to get from there to anywhere, you need to point to an rlb in 86.. and that needs a route to send the digits to.. so if you take eight analog stations, and jumper them to an analog trunk card your 9 plus will work..you can make it the 1st or last choice in the proper rlb

in the route answer supervision no fdec/ndec eth and on the stations add cls xfa and ftr phd.. they may still hang up but not as much.. loop start trunks have had that problem since day 1.. merridian rolm avaya.. no switch can handle loop start without a trunk handing up at times

Thanks John!

I guess I will have to price out an analog trunk card. Do you know what the type is? like 500 being analog station, 2000 digital sets.. is there a type for analog trunk?

This will list any spare trunk TN's in the switch that you can use.

Is there a difference between XEM and EXUT?

 

[LeeMcCauslin]

EXUT= Enhanced Universal Trunk card - can not put Tie trunks on it

XEM = Enhanced E&M - can only put Tie trunks on it (And pag trunks?)

Your XUT cards are Universal TRunk cards too but they are older cards. EXUT cards replaced them.

*Note - the above info is taken directly from notes that I took in M1 Database admin class at Global Knowledge about a month and a half ago. I can't promise you I took good notes. I already don't remember completely what I was talking about. But whatever I got wrong, someone here will fix? I hope.

I am pretty sure that none of those cards are analog line cards, however.
