 As per the PAN-India data most of the exchanges / BMs are working
with only 30% to 40% loading.
 In present Scenario the working ports of LCC Cards are distributed in
a random fashion.

 We need to shift Terminal equipments in such a manner, so that
the working subscriber should be moved to Base Module rack and
then Line Module-01 and Line Module-02 rack.
 In this manner subscribers are organized properly among the
various racks.

Main Advantage
 This is applicable to Co-located BMs and Remote BMs.
 This will lead to power saving.
 It will generate inventory of Control cards of ATU (i.e.
TIC/ISP/TUI) and Power Supply Cards.

MBM Exchange
 The same strategy can be implemented in the MBM exchange.
 The equipment planning for MAX-NG has been done after
considering the BM compression activity.

Pre-Deployment Activity (Contd.)
 Migration of existing BRI connection to alternate solution like
CDMA VPN
 Network Configuration between SDCA and Core switch by MPLS
NOC
 Last Mile connectivity between MAX-NG Aggregator and MPLS
Core through RPR
10-08-2022
20

Pre-Deployment Activity
 Configuration of Required IP addresses at MPLS for MAX-NG VLAN
 Verification of various equipment as per the site configuration and
final BOM.
 Retrofit data preparation for MAX to MAX-NG migration for C5
subscribers creation, Routing and Trunking Data, various Access
Gateway related Data.
10-08-2022
21

Requirement
 The uplink connectivity is through 1GigE Optical patch cord.
 The length of patch cord for the above connectivity.
 The type of connectorization at ADM end of RPR i.e. FC or LC or SC
so that the patch cord can be supplied accordingly.

Deployment Related Activity
 Infrastructure Installation at Main exchange site i.e. 2-Slot and 6-
Slot Chassis.
 Installation of network elements and configuration at Remote site
for the IP connectivity.
 Installation of MAX-NG Access Equipment, EBM, LAN Switch and
Client Terminal at site
 Configuration of LAGs as per Co-located BMs and Remote BMs
 Configuration of MLS as per Network Connection
10-08-2022
23

Deployment Related Activity
 Configuration of MG/SG (if required for POI), V5AG and PRIAG as
per working ISUP Signalling & Media links, AIs and PRI Links
 Network Data Creation in Class-4 SS for connectivity of SDCA to L2
TAX and POIs
 Configuration w.r.t Billing and Provisioning through BSNL CDR
system and Clarity system
10-08-2022

Planning for MAX-NG Installation
 One BM Cabinet at MBM location will be use as MAX-NG BM
 MAX-NG BM will house CACU (Central Access Control Unit) system to
install common elements for that MBM i.e.
Main Aggregation Switch (1+1)
Network Access Gateway Card (1+1)
Ethernet-to-E1 Bridge Main (1+1)
Shelf Manager Card (1+1)

 All the E1s for the Network i.e. POI PCMs, V5.2 AN-RAXs and PRI-
PBX are required to re-route to MAX-NG BM.
 One Card Frame of MAX-NG BM has a provision of DDF to
terminate all the above mentioned E1s.

Planning at Line BM / RSU Site
 At Co-located Line BM / RBM site, new LAGU (Line Access Gateway
Unit) system will be installed in place of bottom two Card frame of
Base Module.
 LAGU system house only 02 nos of NGTJ-LAG Card and 02 nos of TSI
card.
 CAT-5e LAN cable for Co-located Line BM or existing E1 Cables in
case of RSU are directly terminated on the backplane of LAGU system.

Suggestion
Few Suggestion / Maintenance after MAX-NG:
 IPM should be connected at MDF for Lightning Protection
 High Voltage Protection (HVP) module developed by C-DOT to be installed
in the exchange at Heavy Lightning Prone Area
 Proper checking of Earthing of exchange.
 Proper training of MAX-NG maintenance staff.
 Proper maintenance of Power plant, Generator and battery back-up
arrangement.
