2.8.6 Frame Relay Server Specifications
There can be up to three Frame Relay server cards in an integrated access system chassis in
non-redundant operation. The Frame Relay Server performance figure of 4000
Frames/Second was obtained using 64 byte frames. The following hardware and firmware
must be included in a system to add Frame Relay Server operation:
•
8803- CPU Control Card with 8 T1/E1 Cross Connect (redundant-capable)
•
8923/8924xx - 8 T1/E1 Interface card w/ 128K NVRAM
•
8811 - Advanced Communication Server (ACS) with 68 logical Frame Relay ports
•
60520 - Host Firmware version 5.2
•
62160 - ACS Frame Relay Server firmware
2.9 ATM Server Card
Although ATM is being touted as an ubiquitous technology for all business communications
services, the reality is that it is playing a significant role so far only in backbone campus
network for LAN applications for local transport. This section highlights the benefits of the
various applications of the 8820 and 8823 ATM Server cards and demonstrates how it can
effectively and efficiently to deploy various services. The ATM Server Card provides the
ability to provision legacy voice, data, and video services over an ATM backbone via a DS3
or OC3c/STM-1, multi-mode and single-mode.
The ATM Server card includes support for efficient, standards-based ATM adaptation of a
multitude of legacy traffic types. Examples include analog key systems, routers, video codecs
and PBXs. Legacy traffic is directed from T1, E1, data and voice interfaces to the ATM Server,
which then provides ATM adaptation and encapsulation. By providing direct, integrated
connectivity to the ATM network, the system eliminates the need to run parallel networks for
ATM and TDM traffic. The ATM Server Card is based on standards adopted by the ATM
Forum and the ITU. These standards allow the ATM Server to inter-operate with a wide
variety of ATM switches and to adapt multiple traffic types for aggregation and transmission
across an ATM network. Some of the well-known switches include those from FORE, Lucent,
NORTEL, GDC, ADC Kentrox (also listed in a following slide).
Since the ATM Server Card fits in any server slot, service providers can deploy the integrated
access system in non-ATM access networks today, and easily migrate to ATM based access by
simply adding an ATM Server Card. The ATM Server Card, combined with the wide range of
interfaces on the system, provides the most flexible platform for service provisioning in the
market today. The following is a list of the ATM server card key benefits:
