RE: IP Dslams

[Payam Poursaied]

Hi Nick

How many devices are you looking for?

Consider ZyXEL 1248: 
https://www.zyxel.com/uk/en/products_services/48-port-Temperature-Hardened-ADSL2--Box-DSLAM-IES-1248-5x-IES-1248-5xA-Series/

 

For PPP and those stuff, you can rely on MikroTik. 

i.e. https://mikrotik.com/product/rb4011igs_rm @199USD you would have PPP(oE) 
aggregation + user manager panel and much more

Howdy,

We have a requirement for an aged care facility to provide voice and data, we 
have the voice worked out, but data, WiFi is out of the question, so are 
looking for IP-Dslams, preferably a system that is all-in-one, or self 
contained, as in contains its own BBRAS/LNS/PPP server/Radius, such as has a 
property managment API, or even just a webpage manager where admin can add in 
new residents when they arive, or delete when they depart I know these used to 
be available  many years ago, but that vendor has like many vanished, only 
requirement is for ADSL2+, prefer units with either 48 ports or multiples of 
(192 etc) and have filtered voice out ports (telco50/rj21 etc)

If anyone knows of such units, would appreciate some details on them,  
brand/model suppliers if known, etc, we can try get out google fu back if we 
have some steering:)

Thank Y'all

Re: Changing upstream providers, opinions/thoughts on 123.net and cogent

[Brandon Martin]

To reiterate what's been said...

I would not want to be single-homed to Cogent.  They're fine (and 
generally useful and a reasonable use of your operating money) in a blend.


I'm not familiar with 123.net, but looking briefly at them, they appear 
to be a regional blend.  Much preferable compared to your other option 
assuming they competently operate their network.


FWIW, I wouldn't WANT to be single-homed to anyone, but I'll do it when 
it's the right choice.


If you have to be single-homed, you really have to go with a quality 
upstream, and you're going to pay for it.  If you have the volume and 
connectivity to be multi-homed, do it.  It'll be better in just about 
every way.

Hi Aaron,

I don't know anything about 123.net.

Google "Cogent cake," "cogent sprint," and "cogent telia" for
explanations and examples of how relying on Cogent as your sole
transit provider is likely to bite you in the behind. Using them as a
secondary transit provider in a BGP-managed mix is arguably more
acceptable.

Re: IP Dslams

[Rob Pickering]

Just a thought, would a two wire Ethernet extender technology (eg
Phybridge) provide you with a simpler solution?  xDSL needs a lot of
infrastructure for a low port count (& budget) application.

I have no idea if you can split the baseband out to provide POTS over the
same pair, but even if you can't, Ethernet plus a VoIP phone or ATA to each
unit may end up cheaper than a shed load of carrier oriented xDSL infra?

Dear all,

NTT / AS 2914 deployed explicit filters to block this BGP announcement from
AS 4134. I recommend other operators to do the same.

I’d also like to recommend AS 32982 to remove the AS_PATH prepend on the
/24 announcement so the counter measure is more effective.

Kind regards,

Job

Changing upstream providers, opinions/thoughts on 123.net and cogent

[Aaron Henderson]

I work for a rural ISP and the powers that be have been thinking about
changing our upstream providers. The big names on the table right now are
123.net and Cogent.

I, along with the people in my circle, do not have any experience with
these providers and all we are getting is what sales are dishing us.

I was hoping some of you here might have experience with these providers
and could share your experiences and opinions.

Thanks,

A

Yep, that's probably the one you want to look at.  I've got one on a 
shelf.  Looks like a nice box.  Pity it has no firmware on it.


It does not have POTS built in, so you'd have to generate that somehow. 
 An old Adit 600 with a bunch of FXS cards and CMG router might do it

I was thinking the same thing. They're a few years out of support, but the 
Zhone 42xx IP DSLAM provides a 1Gbps ethernet uplink and 24 ADSL2+ DSL user 
ports per 1U chassis (stackable to achieve 192 ports total). Wish they were 
available in AC for non-telco use.

 You could pair these with a pfSense appliance (or an x86 PC running the free 
software) to provide DHCP, DNS, etc - or use the built in pfSense captive 
portal to provide additional authentication and accounting per user. pfSense 
can provide NAT and FW if needed, or these features can be disabled to use 
globally routable IP4/IP6 addresses.

 As far as support goes, backup your pfsense and DLSAM configs when you finish 
the project and the subscriber accounts and DSL modems could be maintained by a 
local admin through the pfSense web interface with no need to touch the DSLAMs 
or anything CLI.

 Is there a logical way to distribute the termination?  You might be able 
 to get better performance (not that you perhaps care, in this case) at 
 minimal additional cost if you can do building-local termination of each 
 customer circuit and then backhaul on e.g. bonded VDSL2 or G.FAST over

 I'm assuming there's no data grade copper or fiber if there's no coax.

 If you do want a centralized solution, an Adtran TA5006 (the small 
 chassis) with 6x 48 port VDSL2 combo modules (with or without vectoring, 
 depending on your needs) would do the job (though it fills the chassis 
 and doesn't allow for expansion, so the full-size TA5000 may be

Are you sure you need all of that?

When I designed ADSL solutions ~15 years ago I built with Paradyne DSLAM 
with ethernet uplink, then we used rfc 1483 bridged over ATM, so no need 
for PPP, radius or anything. It was just IPoETHERNEToATM and all the 
regular IPoE mechanisms could be used (DHCP etc).


So we just bundled the DSLAM with an L3 switch and that was that. One vlan 
per customer which solved the customer isolation problem. Customer could 
run modem in either bridged mode or terminate the IPoETHoATM PVC on the RG 
itself.

You might start hunting on the used market for Occam/Calix B6 equipment,
specifically the B6-252 ADSL2+ and POTS card and the 12 slot chassis.

You'll have to put in some supporting infrastructure, but they do work
well, and I know of at least two aftermarket repair places that will repair
them for a reasonable (for the telecom world) cost.

Might want to look for old Zhone ip bitstorm dslams.  There should be a bunch 
on the used market.  They do all of the ATM conversions internally so you just 
need to feed them with ethernet.

 Is there a logical way to distribute the termination?  You might be able 
 to get better performance (not that you perhaps care, in this case) at 
 minimal additional cost if you can do building-local termination of each 
 customer circuit and then backhaul on e.g. bonded VDSL2 or G.FAST over 
 shorter distances (perhaps hopping building to building).

 I'm assuming there's no data grade copper or fiber if there's no coax. 
 Obviously if you've got those, distributed termination makes even more 
 sense.

 If you do want a centralized solution, an Adtran TA5006 (the small 
 chassis) with 6x 48 port VDSL2 combo modules (with or without vectoring, 
 depending on your needs) would do the job (though it fills the chassis 
 and doesn't allow for expansion, so the full-size TA5000 may be 
 desirable).  I've played (and am playing with) the same system but with 
 GPON termination and have been happy with it so far.

Re: 192.208.19.0/24 hijack transiting 209, 286, 3320, 5511, 6461, 6762, 6830, 8220, 9002, 12956

[Job Snijders]

Dear all,

NTT / AS 2914 deployed explicit filters to block this BGP announcement from
AS 4134. I recommend other operators to do the same.

I’d also like to recommend AS 32982 to remove the AS_PATH prepend on the
/24 announcement so the counter measure is more effective.

Kind regards,

Job
