Paradyne 3000 manual Technical Specifications, Environment

Introduction

Network Interface Modules (NIMs) can be installed at the rear of the carrier (when not occupied by an Auxiliary Backplane) to provide the PSTN (dial) or switched

56 kbps digital service interface for both DSUs and dial/lease modems. There are nine different NIMs. For a list of the feature/part numbers of these NIMs, see Appendix B of this manual.

Alternatively, you can install up to two Auxiliary Backplanes at the rear of the carrier to allow Model 3151 T1 CSUs and Model 3161 T1 DSU/CSUs to provide an interface between a T1 digital network and Customer Premise Equipment (CPE).

A modular DSU or dial/lease modem is a circuit card that contains ªgold fingerº contacts on the rear edge of the card and is supplied with a rear connector plate. A rear connector plate has two DTE connectors, a 25-pin EIA-232 connector and a 25-pin CCITT V.35 connector. It allows removal of a modular circuit card without disconnecting the DTE cables at the rear of the carrier. Also, there are connector modules which have six ports and are supplied with the modular DSU-TDM or

DSU-MCMP circuit cards. These connector plates and modules function as interfaces between the modular circuit cards and the DTEs.

This manual describes the procedure for installing a COMSPHERE 3000 Series Carrier into a COMSPHERE 72-inch cabinet. A COMSPHERE 72-inch cabinet with available equipment-mounting dimensions of 63 inches high by 19 inches wide has the capacity to hold up to six carriers, allowing for a high-density installation combination of up to 96 DSUs and/or dial/lease modems. COMSPHERE 3000 Series Carriers can also be mounted in other types of EIA standard 19- or 23-inch wide cabinets. (The heights of the other types of cabinets may vary.)
