Introduction

Overview

The CSP 2090 and CSP 2110 are both non-blocking 2000-plus port switches, uniquely designed to meet the demands of contemporary telecommunications by delivering high-performance, fault tolerant switching in a compact microprocessor-based design. A typical mid-range configuration consists of: a 2,048 port CSP Matrix Series 3 Card residing in a 20 slot chassis, a fully configurable combination of line and services cards, and a host interface.

The CSP 2090 and CSP 2110 support common channel signaling packet engines for both ISDN and SS7 communications. Line protocol cards include E1, T1, DS3, and J1 services. Standard and custom tone generation and reception, precise call analysis, conferencing and voice recorded announcements are provided through an advanced Digital Signal Processing (DSP) unit available for the CSP. The CSP communicates with the host application using Ethernet links.

The CSP 2090 and CSP 2110 can operate as either a stand-alone switch, or as a node in a larger system, supporting scalability to over 30,000 non-blocking ports.

A digital communications link - voice, data, and video at a 2.048 Mbps rate; 30B/2D or 31B/1D (ISDN); non-North American version of T1.
Digital communications link - voice, data, and video at a 1.544 Mbps rate (24 64 Kbps channels)
Digital Signal Processor
The protocol used in most local area PC networks. Typically, most Ethernet networks support data transmission speeds up to 10 Mbps, but 100 Mbps is also possible.
Notation that describes line card redundancy, where N is the number of installed line cards of a single card type and 1 is an additional line card of that type designated as a standby card. For example, if you have three T-ONE cards and one additional standby T-ONE card installed, the system provides redundancy by activating the standby card if any of the three active T-ONE cards fail.
PPL. Excel feature allowing support of custom protocols, designed through a graphical interface tool. Protocol is defined by associating a State Event Table with a Primitive Table. See State Machine.
