Preface
The objective of this manual is to provide necessary information & guidance for the installation of an RSU.
Since most of the chapters for RSU installation, viz. Grouting, Iron Work installation, Cabinet installation, D.C. Distribution Panel, MDF installation, Power
Distribution Panel installation, Cable Preparation and laying, Fuse Details and
Placement, Jumper Settings, Expansion with Line Module etc. will be similar to those which are covered in SBM RAX installation manual. For installation of ISDN
Terminal Unit (ISTU) in RSU, refer MAX-XL Installation Manual. Only those points where there are changes/modifications and extra work to be done, are covered in this document along with the figures. Apart from the installation procedure to be done on the RSU side, there are few changes and extra cable preparation and laying to be done in the parent exchange (C-DOT DSS MAX) for
RSU installation which are also covered in this document. We hope that this manual will serve as a useful reference for the installant alongwith respective SBM
RAX Installation document for RSU Installation.
Following configurations are possible as per field requirement.

Introduction
1.1. GENERAL
RSU, by definition, is the Remote Switching Unit of a geographically distributed exchange being controlled by the parent exchange, which has the capability for local switching. For all purposes, RSU is similar to a colocated BM in an MBM exchange.
The only difference in RSU and colocated BM is that RSU placed remotely will be connected to parent exchange by digital trunks interface from CM to RSU via respective MDFs and digital media while colocated BM is connected to CM by BM-
CM data cables and clock cables. Hence RSU is also termed as Remote Base Module
(RBM) and names `RSU' and `RBM' are interchangeably used in this document wherever necessary. With the present hardware only an even number BM of MBM
(i.e. BM-2, BM-4, etc.) can be made as an RSU. Hence maximum number of RSUs that can be supported in C-DOT DSS MAX and corresponding RSU cards required are given in Table 1.

Since there will be no IOPs and ADP on RSU side, a CRP terminal can be extended through modem for maintenance purposes. It should be clear that a Base Module in
C-DOT DSS MAX can be converted into a Remote Base Module (RSU) with minimum changes.
Following are the changes required on RSU side and main exchange side for connecting a RBM to main exchange.
RSU INSTALLATION MANUAL 5
Chapter 1.
1. Only an even numbered BM can be made as an RSU
2. RSU Side :
(BM-L/BM-XL)
- To distinguish between a Remote Base Module and colocated Base Module, the Most Significant Bit (MSB) position on each column of jumper settings on copy 0 and copy 1 side of Base Processor Unit (BPU) mother board is made one, i.e. it is left open.
- Time Switch Switch (TSS) card will be replaced by
Enhanced Remote Time Switch (ETS) card.
- For connection with the parent exchange, two sets of digital trunk cables for Bus-0 and Bus-1 from the Time
Switch Unit (TSU) of RBM will be laid towards the
DDF/MDF.
3. CM Side - On the CM side, Space Switch Multiplexer card in Bus
Termination unit will be replaced by Enhanced Remote
Space Switch Multiplexer in the slot where a RSU link is to be connected as given below.
CM-L : SSM replaced by ESL
CM-XL : PSM replaced by ESM
- Two sets of digital trunk cables coming from the RSU (i.e. from DDF of CM side) as Bus-0 and Bus-1 will be terminated on to corresponding bus of ESL/ESM card in
BTU. The other position in the same ESL/ESM card will be used for connecting a colocated BM.
Note:
Each SSM/PSM supports two local BMs
Each ESL/ESM supports one local BM and one RBM.

Modifications in Floor Marking
2.1. MARKING OF SUITE LINES
The suite lines are drawn as per the procedure outlined in section 1.5 of respective
SBM RAX installation manual. Since there will be no IOPs and ADP in RSU, the suite lines will be as shown in Fig. 2.1. To draw the suite lines the distance of
600mm, 2995mm for Base Frame Assembly-1, 3000mm and 3985mm for Base
Frame Assembly-2 parallel to the second datum line is measured and four vertical lines are drawn. Also two horizontal lines at a distance of 400mm and 1000mm parallel to the first datum line are drawn. The intersection of respective horizontal and vertical lines give the physical placement of the suite. Also markings for placement of CRP terminal are made as per figure 2.1 in the switch room.

RSU Cable Preparation And Laying
3.1. INTRODUCTION
Following are the main cables required for RSU installation apart from the other cables mentioned in C-DOT SBM RAX/DSS MAX-L/XL installation manual. a. RSU Clock cable. b. Digital Trunk Cables on RSU side. c. Digital Trunk Cables on Central Module (CM) side. d. BP Terminal cable on RSU side.
Co-axial cable is used to prepare the clock cable for RSU. Clock cable will be connected between ETS (Enhanced Remote Time Switch) card slot position and TSC
(Time Switch Controller) card slot position on each copy of TSU. Since the connections on the contact blocks at both ends are not one-to-one, care needs to be taken by the installer while fixing it on the mother-board.
Digital Trunk Cable on RSU side is connected from Time Switch Unit to DDF. On
CM side, it is connected between Bus Termination Unit (BTU) and DDF. The shield at DDF end of these cables are connected to chassis ground. Other end of the cable shields (RBM and CM side) should be left open to isolate the ground.
Assembly of the digital trunk cable on RSU side also provides connection to an
ACIO cable. For ACIO part, jumper wire with PVC sleeve may be used.
BP terminal cable is optional only. This may be required for debugging switch units in case RBM is totally cut off from the parent exchange and it is having critical switch unit faults.
One CRP terminal is extended through modem on RSU side for maintenance functions. This does not require any additional cables as Modem is normally supplied alongwith a cable which is having D-type 25 pin connectors on both ends.

Configure another modem as answer modem as follows :
Connect terminal to modem, set terminal speed to 9600, power on modem and type the following. On typing 'AT', response from modem should be "OK".
AT&F8&W0 ↵
AT$SB9600&W0 ↵
AT$MB9600&W0
AT&E3&W0 ↵
↵
(Store default settings and save)
(Serial baud rate set to 9600 and save)
(Modem baud rate set to 9600 and save)
(Disable flow control and save)
AT&D0&W0 ↵ (Ignore DTR signal and save)
Now set the jumper inside modem as follows :
Set lease/dial to lease position.
Set originate/answer to answer position
Step 3:
Verify IOP serial port by connecting a terminal, login should appear and it should be possible to login. Connect answer modem RS232 port to this IOP port. Connect terminal to RS232 port of originate modem connect line jacks
(RJ11) of both modems by using a shorting cable supplied for leased line working (simulating cable pair between modems or 64 kbps data circuits).
Now power on modems, CD lamp will glow in both modems and link is established login should appear on terminal.
Please note that when terminal/IOP port is connected to modem, TR lamp should glow in modem.
Note :
If login does not appear in icc port when terminal is connected, edit file "init tab" in / etc directory using vi editor. In line wherever required icc port is available, replace "off" by "respawn", save the file.

5.1. GENERAL
The MDF installation, on the RBM side, is similar to the MDF installation for C-
DOT-SBM RAX in respect of subscriber and trunk cabling. However the additional cabling is required for RSU installation on the RBM side and on the parent exchange side in respect of 16 PCMs between parent exchange and RBM.
5.2. DIGITAL TRUNK CABLE TERMINATION ON RBM TO MDF (FOR RSU
PCMS) a) 16 PCMs i.e. L1 to L8, L17 to L24 are terminated on 4 Nos of 2/8 LSA modules. b) If 4 pair cable is used from TSU frame to MDF, terminations on MDF are done as shown in figure 5.1 (a). If 8 pair cable is used from TSU frame to
DDF, terminations on MDF are done as shown in figure 5.1 (b). c) Cables marked RNUU, RNVV coming from copy – 0 of TSU are terminated on first 2/8 module as shown in figure. Cables marked RNXX, RNYY coming from Copy – 0 of TSU are terminated on second 2/8 module as shown in figure. For cables coming from copy – 1 of TSU termination is done on third & fourth modules. Termination is done in the same way, as done for copy – 0 cables. d) For digital trunk cable preparation using 4 pair shielded cable & placement details, refer to sections 3.2.2.1 & 3.2.2.2. For digital trunk cable preparation using 8 pair shielded cable & placement details, refer to section 3.2.2.3. e) The grounding leads coming out from digital cables at the ends near MDF can be crimped to a ring terminal and terminated on one of the screw & nut holding same backmount frame as shown in Fig. 3.2 c.
