Chapter 1 Introduction 1.1 Overview This manual describes the technical characteristics, applications, installation and operation of the HS-RN four-channel low-speed data modules for use in Megaplex-2100, Megaplex-2104, and Megaplex-4100 integrated access multiplexers.
Chapter 1 Introduction Installation and Operation Manual • The local DTR state determines the remote DSR state, and vice versa • The local RTS state determines the remote DCD state, and vice versa. Basically, each HS-RN channel is assigned an individual timeslot in the E1, T1 or SDH/SONET uplink. The HS-RN modules also support split timeslot assignment, therefore improving uplink bandwidth utilization. The user can assign the timeslots and timeslot bits to HS-RN channels manually.
Installation and Operation Manual Chapter 1 Introduction Figure 1-1. Low-Speed Data Connection Figure 1-2 shows a typical Point-to-Multipoint application. Figure 1-2. Point-to-Multipoint Connectivity at Low Speed Data Transfer Unidirectional Broadcast Mode Applications The unidirectional broadcast mode enables a user at a central location to send data to multiple users connected to remote Megaplex units (simplex communication), while using only one timeslot.
Chapter 1 Introduction Installation and Operation Manual The timeslot assigned to user A on one of the internal TDM buses is routed to the two main link ports of the Megaplex unit at location A, and can be inserted in timeslots with different numbers.
Installation and Operation Manual Note Chapter 1 Introduction The timeslot can be connected in parallel to any number of channels. • In the reverse path (to location A), the timeslot is always bypassed from port 2 to port 1, en route to location A.

Installation and Operation Manual 1.3 Chapter 1 Introduction Physical Description The HS-RN is a 4U-high module that occupies one I/O module slot in the Megaplex chassis. All the functional configuration parameters of the modules are determined by software. Jumpers are used only to control the connection of ground reference to each channel connector. Figure 1-6 shows a typical HS-RN panel. HS-RN TST LOS CH.1 Test Indicators CH.2 CH.3 LOS Indicators CH.4 CH1 & CH2 Connector Channels 1-2 CH.

Installation and Operation Manual Chapter 1 Introduction TDM Bus Interfaces (Megaplex-2100/2104 only) The HS-RN module has four independent TDM bus interfaces, one for each Megaplex-2100/2104 TDM bus. Each TDM bus interface is used to connect timeslots from the corresponding bus to the internal routing matrix of the HS-RN module, in accordance with the commands received from the CL module. HS-RN can use all the four TDM buses.
