Chapter 1 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. Note 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.

MP-2100 HS-R Installation and Operation Manual Introduction 1.2 Physical Description The HS-R modules occupy one I/O module slot in the Megaplex chassis. Figure 1-3 shows the panels of the 4U-high HS-R module.
MP-2100 HS-R Installation and Operation Manual Introduction 1.3 Functional Description Main Features Each HS-R channel operates independently. All the channel operating parameters are controlled by Megaplex system management. Basically, each HS-R channel is assigned an individual timeslot in the T1 or E1 main link frame. The HS-R modules also support split timeslot assignment, therefore improving main link bandwidth utilization. The timeslots assigned to HS-R channels can be manually assigned by the user.
MP-2100 HS-R Installation and Operation Manual Introduction • At 56 kbps, an 8-bit frame is used. This frame uses seven frame bits for transparent transfer of the user's 56 kbps data stream, and the eighth bit is always “1”. • At 64 kbps, no framing is used (transparent transfer of user's data stream).
MP-2100 HS-R Installation and Operation Manual • Introduction EXT DCE (DTE1): the interface provides a receive clock signal to the user's DTE, and accepts the transmit clock from the user's DTE. The user's DTE must operate with loopback timing; that is, it must transmit at the rate of the receive clock signal provided by the HS-R channel interface. This timing mode is suitable for tail-end applications.
MP-2100 HS-R Installation and Operation Manual Introduction additional slot would be used for the fourth channel. Thus, two full timeslots would be required. The maximum number of main link timeslots that may be required by an HS-R module is four. The user can enable split timeslot allocation. In this case, each channel which does not require a full timeslot can be allocated the required number of bits (in accordance with Table 1-1 in a user-selected timeslot.

Chapter 2 Module Installation and Operation 2.1 General This chapter provides installation and operation instructions for the HS-R modules. The information presented in this chapter supplements the general installation and operation information appearing in the Megaplex-2100 System Installation and Operation Manual. Warning Before performing any internal settings, adjustment, maintenance, or repairs, first disconnect all the cables from the module, and then remove the module from the Megaplex enclosure.
MP-2100 HS-R Installation and Operation Manual Module Installation and Operation 2.2 Preparation for Installation The HS-R modules have two jumpers that control the connection of the frame ground to pin 1 in the channel connectors. Default setting: pins connected to frame ground. Figure 2-1 shows the location of the two jumpers for the HS-R. Note that the modules include additional factory-set jumpers that must not be changed by the user. Jumper J3 FGND Frame Ground not Connected to Pin 1 of CH.
MP-2100 HS-R Installation and Operation Manual Module Installation and Operation 2.3 Module Connections Interface Data The connection of user’s equipment to HS-R modules is made to the two 25-pin D-type female connectors located on the module panel Table 2-1 lists the pin assignment of the CH. 1-2 connector, which serves Channels 1 and 2. The wiring of the CH. 3-4 connector, that serves Channels 3 and 4, is similar. Table 2-1 CH.
MP-2100 HS-R Installation and Operation Manual Module Installation and Operation Cable Connections Identify the cables intended for connection to each port of this module, and connect them into the appropriate connectors. Two channel splitter cables are available from RAD. These enable direct connection of data equipment with RS-232 interfaces to an HS-R channel connector: • CBL-HSR/F, which terminates into two 25-pin D-type female connectors.
Chapter 3 Configuration Instructions 3.1 Introduction This chapter provides information on the configuration parameters of the HS-R modules. The configuration activities required to select the desired values of these parameters are performed by means of the management system used to control the Megaplex unit.

The module generates additional alarm messages, which are not specific to HS-R modules; these messages are explained in the Megaplex-2100 System Installation and Operation Manual.
MP-2100 HS-R Installation and Operation Manual Tests & Diagnostics 4.4 Troubleshooting Instructions The loops available on the HS-R module provide a rapid and efficient way to identify the general location of a fault either of the HS-R modules connected in a link, in the external equipment, or in the connections to the channels.
Appendix A Operation with FCD-E1M and FCD-T1M Operation of the HS-R module with FCD-E1M and FCD-T1M is generally similar to its operation with the Megaplex-2100/2104 family of modular E1/T1 multiplexers, as previously explained in this manual. The differences are seen in the following two areas: • Configuration parameters • Alarm messages This appendix identifies and lists these differences only.
