ATM Notes
US West's 'Nterprise rolls out ATM service
US West announced the beginning of its ATM Cell Relay Service (CRS)
throughout its operating territory. The new ATM CRS service, which is
provided by 'NTERPRISE Networking Services (a subsidiary of US WEST),
will offer entry-level pricing for an ATM DS-3 port and access link at
$1,150 per location. An ATM OC-3 port and access link is priced at
$1,500 per location. According to US West, charges for inter-office
transport are $30 per megabit for Class A constant bit rate (CBR)
traffic and $37.50 for Class C variable bit rate (VBR) traffic. A US
West press release includes uses further details on the carrier's
pricing structure. The carrier also announced a multi-year expansion
plan for its ATM services. Beginning in Q3 1995, US West will offer
connectivity to inter-LATA markets using ISDN (B-ICI) IXC at both 45 and
155 Mbps. By 1997, US West plans to offer switched virtual circuit
(SVC) support along with 622Mbps service. (Business Wire, January 30,

Unclog your local backbone with ATM
This feature article in the February edition of Datamation magazine
(tel. 617/558-4281) makes the case that ATM is an extremely attractive
LAN backbone solution -- that is, if you avoid "messy" aspects of the
technology, such as routing, LAN emulation, IP traffic over ATM, etc.
The article, which describes ATM, in general, as expensive, confusing
and incomplete, does, however, recommend the current generation of
products for use as a "fat pipe" for legacy LAN traffic. Basic
definitions are offered for some of the concepts and acronyms
(latency, buffering, PVCs/SVCs, etc.) that one is likely to encounter.
In a nutshell, the "safe and sane" advice offered to LAN managers is
this: add ATM interfaces to all routers that can handle ATM, remove
routers that cannot and choose your ATM switches very carefully.

Bell atlantic goes flat out to offer flat rate ATM service
The current edition of Network World (http://www.nwfusion.com)
provides greater detail on the flat rate fees Bell Atlantic plans to
charge for its newly- announced ATM service (see ATM Digest v3n110).
According to the article, Bell Atlantic's flat monthly fee for a DS3
connection (with 10 to 45Mbps of bandwidth) will range from US$3,000
to US$4,200; a direct fiber OC-3C connection (with 25 to 155Mbps of
bandwidth) will range from US$3,800 to US$6,500; and a SONET OC-3C
connection (with 25 to 155Mbps of bandwidth) will range from US$5,500
to US$8,200 -- with no usage or mileage charges. (Network World, June
