Introduction

1.1 Overview

This manual describes the technical characteristics, applications, installation and

operation of the HS-R four-channel V.110 data modules for the Megaplex-2100

and Megaplex-2104 family of modular E1/T1 multiplexers.

In this manual, the generic term Megaplex is used when the information is

applicable to both chassis versions. The complete designation is used only for

information applicable to a specific version.

Applications

The HS-R modules provide four independent RS-232 channels that support full

duplex asynchronous and synchronous data transmission in the range of 0.6

through 64 kbps.

The HS-R modules perform rate adaptation in accordance with ITU-T Rec. V.110;

multiplexing is performed in accordance with ITU-T Rec. I.460. In addition, the

main link data stream generated by the HS-R module is compatible with the data

stream generated by the ASM-31 and ASMi-31 modems, offered by RAD.

Figure 1-1 shows a typical low-speed data transmission application using HS-R

modules. In this application, two HS-R modules are used to connect remote

terminals to a server or communication controller through the Megaplex link. The

HS-R modules enable efficient utilization of link bandwidth; for example, the HS-R

modules enable the transmission of four 9.6 kbps channels in one 64 kbps timeslot

(see Section 1.3 for additional details).
