ACC claims Remote Dial-up Access Concentrator supports Voice/IP, SS7, NEBS, and protocol selection "on the fly." Some of these features are cited as futures. Interesting, nonetheless. Anyone notice that it is getting crowded in this sector?

ACC Unveils Flagship Remote Access Concentrator for Carrier Market; Tigris 11-Slot Delivers Unrivaled Port Density, Reliability and Multiservice Support

NetWorld+InterOp98
SANTA BARBARA, Calif.--(BUSINESS WIRE)--April 27, 1998--Advanced Computer Communications (ACC), a leading provider of network access solutions, Monday announced Tigris 11-Slot, the flagship product of the Tigris family of remote access concentrators scheduled to debut at NetWorld+InterOp in Las Vegas, May 5 through 7.
Tigris 11-Slot delivers unequaled port concentration, system redundancy and multiservice support, making it the best value in its class for Internet service providers (ISPs) and public carriers.
Its modular scalability, redundant architecture, modem density and rich feature set enable providers to maximize usage of premium central office real estate and minimize costly downtime, while increasing business through competitive service offerings such as wholesale Internet and corporate access and support for emerging technologies such as Voice/IP, V.90 modem and ATM.
"The buying power of the carriers combined with dramatically increasing IP-traffic demands are dictating a new class of products and services in the remote-access market," said Brad Baldwin, director of Remote Access Research at IDC. "The Tigris 11-Slot, with its high port density, PSTN off-load capabilities and support for multiservice connectivity options, is very well positioned for this emerging market."
Maximum Reliability, Maximum Concentration
Tigris 11-Slot leverages the carrier-class design of its 3-Slot and 7-Slot predecessors by incorporating a shelf built to NEBS specifications, hot-replaceable cards, load sharing and redundant power supplies, and redundant cooling fans.
Additionally, the 11-Slot integrates a redundant, high- performance control card that maximizes system reliability while increasing performance to support up to 252 Primary Rate ISDN or T1/E1 lines. A two gigabyte packet bus ensures low latency packet transfers for delay-sensitive applications such as Voice/IP.
With 9 slots available for interface cards, Tigris 11-Slot is capable of supporting up to 1,344 modem connections and 6,048 ISDN B channels per shelf, with up to 5,376 modems per 8-foot rack. Support for Multichassis PPP enables even higher densities by allowing Tigris units to share and aggregate channels between chassis.
Because Tigris utilizes DSP-based "soft modem" technology, DSP resources are intelligently assigned "on the fly" to support a wide variety of services, including V.90 modem, ISDN, GSM mobile and Voice/IP.
ACC's exclusive Call-by-Call technology enhances this capability by assigning call attributes, such as connect speed, compression and voice quality on a per-call basis, eliminating the need to dedicate ports to specific service profiles. This flexible architecture makes the Tigris solution the most cost effective on the market today for providers offering differentiated access services.
Multiservice Support
From a single Tigris chassis, providers can offer wholesale Internet access, outsourced corporate access, traditional Internet access, and any combination of dial-up and dedicated services, without dedicating resources to specific applications.
ACC plans to further enhance Tigris' multiservice capabilities with the introduction of an ATM interface later this year that delivers high-capacity dial and dedicated traffic to the ATM backbone and enables switched virtual circuits for virtual private networks (VPNs).
Tigris is also designed to support Signaling System Number 7 (SS7), the standard protocol for conveying signaling information between switching systems in the public switched telephone network (PSTN). SS7 support enables PSTN off-load capabilities and value-added intelligent network services and will be available later this year.
Virtual Private Networking
Tigris 11-Slot supports a comprehensive suite of VPN features, including Layer 2 Tunneling Protocol (L2TP), modem pooling and class-of-service attributes, enabling VPN providers to guarantee levels of service to their customers and differentiate their offerings.
ACC's award-winning Virtual Port Service Manager (VPSM) software tool enables service providers to manage all ports provided by a network of Tigris remote access concentrators as a virtual pool of resources that can be dynamically assigned to subscribers at call setup.
Because network availability is based on virtual ports distributed across multiple POPs rather than physical ports tied to a specific location, VPSM enables providers to oversubscribe their services, broaden their coverage and increase their customer base.
VPSM also provides "just-in-time provisioning" that allows providers to accommodate increases in subscriber usage in real-time by dynamically shifting resources to specific VPN customers.
Pricing and Availability
Prices for Tigris 11-Slot start at $25,995. Tigris 11-Slot begins shipping in August 1998.
About Tigris
The Tigris family of integrated access concentrators combines dial-in and dedicated access with wide-area networking and superior routing. The family comprises 3-, 7- and 11-slot access platforms and a series of optional dual 10/100Mbps LAN, universal WAN, multifunctional DSP resources and T1/E1 modules.
The NEBS-compliant platform consolidates equipment and access lines, maximizes network flexibility, simplifies management and maintenance, and ensures reliability.
Tigris is the only remote access concentrator that gives carriers and ISPs a comprehensive solution to meet their customers' class-of- service requirements.
To maximize traffic throughput under congested link conditions, Tigris uses ACC's exclusive Express Queuing feature to assign priority levels to traffic according to Layer 3 protocol type, source and destination address. The company takes this a step further with Fast Path Queuing, which allows users to specify the link path based on traffic type and/or address.
Additionally, Tigris speeds up modem training by creating modem service profiles that pair dial-in users with their modem specifications. Modems can be set for specific connectivity speeds, maximum speeds and compression.
