DACS vendor
by Peter Polasek 24 Sep '99

24 Sep '99

We are considering using Digital Access Cross Connect units (DACS) to split T1 local loops into fractional T channels. Given that our current knowledge of DACS does not extend significantly beyond the ability to spell the acronym, I am soliciting advice from the network group for recommended hardware vendors. Cost is not an object, we are primarily concerned with choosing the 'industry standard' manufacturer with the highest reliability and knowledgeable technical support. Please share your experiences (positive or negative) with DACS equipment. In an effort to minimize traffic on the NANOG list, I request that responses be sent to my e-mail address and I will submit a summary when all the votes are in. The vendors under consideration now are Adtran, Eastern Research, StarDAX, and Fisher Price (we have some reservations about the latter product). Thanks in advance, Peter Polasek pete(a)brass.com

Re: DACS vendor (additional details)
by Ron Buchalski 23 Sep '99

Peter, A simpler solution which would require less space, power, money, wire pairs, and administration for your group: 1) Provision a few Channelized DS3s into your LEC network 2) Install Channelized DS3 into your router 3) Let the LEC be responsible for owning/managing the DACS, and provisioning the FT1s/T1s onto the T1s within the channelized DS3s. You'll save the space and power normally required for banks of T1 CSUs and the DACS, and you won't need to manage the crossconnects for the DACS. Circuit-wise, it should cost you less to provision your T1s into your facility via a few DS3s rather than fifty T1s, and you won't eat up your incoming telco wire facilities quickly. >From: Peter Polasek <pete(a)cobra.brass.com> >To: Richard Newcomb <rnewcomb(a)pathone.net> >CC: Peter Polasek <pete(a)cobra.brass.com>, nanog(a)merit.edu,Derrick Bishop ><derrick(a)cobra.brass.com> >Subject: Re: DACS vendor (additional details) >Date: Thu, 23 Sep 1999 10:05:05 -0400 (EDT) > > > >On Wed, 22 Sep 1999, Richard Newcomb wrote: > > > Peter, > > > > What is your configuration need, and capacity(payload) requirement > > regarding bandwidth.

Nanog-17 attendees, As co-host for NANOG-17, we hope to make your stay in Montreal a memorable one. We are planning a few activites to take place during the pre-NANOG weekend. Hopefully many of you will be flying in a day or two early to get a chance to see our beautiful 357 year old city, with its french culture and unique attractions. Due to the large number of attendees, I would appreciate some quick feedback on interest on the following activities so that we may book enough spaces and transportation for each activity: Visit: Teleglobe International Network Operations Center, Sunday morning and after tutorials on Sunday. This is a futuristic NOC complete with giant sized video screens, etc.... FREE 10am, 11am, 6pm. Fun: Indoor all-weather Go-Karting (9 horsepower go-karts, the most powerful available indoors). Includes overalls, helmet, computerized timing, warm-up, qualifications and final race. Three sessions totalizing 30 minutes of driving time. Podium with trophies and/or medals, etc.... 9pm to midnight on Sunday night. Cost: $35 CDN ($24 USD) per person, free transportation courtesy of Nortel Networks. More fun: Informal pub crawl for Saturday night. Visits to pubs/clubs on Crescent street and Old Montreal. Pay-you-own-beer. Night life: If the weather is good and there is enough interest, visit to Montreal's rooftop nightclub, Altitude 737 (awesome view, and you get to walk on the roof of Montreal's tallest building, which also houses one of the world's most powerful rotating searchlights). Saturday night, modest cover charge (about $10 CDN). Pay-your-own-drinks. Outdoors: if enough people are interested and the weather cooperates, climbing (hiking, really) of Mont St-Hilaire, nice 1000 foot or so mountain about 30 minutes east of Montreal. Free transportation. SATURDAY. Email me directly so that I may evaluate demand for each activity. We'll be putting up an e-commerce web site early next week to book the Go-Karts.

I have a question... I am currently expanding our network to accommodate a T1 to the Internet and a 512K frame connection to our WAN.. I need to purchase a router and spoke to several vendors. I have heard conflicting stories regarding the model of Cisco router I should get. One vendor <vendor a> tells me that I should get a 2620 with 2 Wan Ports and the other vendor <vendor b> is telling me that I might compromise my security by using one router for WAN and Internet connections. Their suggesting that I get 2 routers one for my Wan and another for the Internet connection... Vendor B is telling me that it would be possible to enter our wan without touching our firewall should someone be able to hack into our IOS on the router... I decided to go the experts... I would appreciate any helpful suggestions. Thanks... -Gerry
