3. Overview of GPON Technology
The most important aspect of PON architecture is its simplicity.
 The Optical Line Terminal (OLT) is the main element of the network and it is usually placed in the
Local Exchange or a NOC of a township.
 Optical Network Units ONUs serves as an interface to the network and are deployed on a customer’s
side.
 ONUs are connected to the OLT by means of optical fiber and no active elements are present in the
link.
 A single ONU can serve as point of access for one (Fiber to the Home) or multiple (Fiber to the Block
or Curb) customers and can be deployed either at customer’s premises (Fiber to the Home or Block) or
on the street in a cabinet (Fiber to the Curb).

GPON STANDARDS
 A big advantage of GPON over other schemes is that it interfaces to all the main
services are provided and in GFP enabled networks, packets belonging to different protocols
can be transmitted in their native formats.
As in modern networks the security of transmitted data is a key issue. A sophisticated mechanism
based on Advanced Encryption Standard and a complex exchange of unique keys is built into the
GPON architecture.

7.  Bandwidth rate limiting is done on an ONT port level.
 Internet user shall be rate limited corresponding to the connection speed
subscriber with the ISP, but the down side is, if the customer upgrade his/her
connection speed, for ex 512Kbps to 1Mbps, it has to be coordinated with
the our team to allow the rate limiting to be increased on the ONT port.
 Voice requires a maximum of 64Kbps.
 IPTV bandwidth requirement is set to a standard 6Mbps which is in
accordance with the service provider standards.
 With all the triple play services, an average bandwidth of 20Mbps is utilized
per ONU.

8. PLATFORM MANAGEMENT MODULE (PMM)
The T7 chassis-based OLT includes one slot for the Platform
Management Module (PMM), which is the primary interface for
external management applications. The PMM utilizes XML and
SNMP (v2c or v3) for in-band or out-of-band communication with the
TRIDENT7 Element Management Suite (T7 EMS) or other network
management platforms in order to coordinate the operation of other
modules in the OLT and its subtended ONTs. A command-line
interface may be accessed with Telnet, SSH, and local craft port.
The PMM supports programmable input/output connections for
central office and housekeeping functions. The functionality of the
PMM in integrated within the Compact OLT.

9. PLATFORM SWITCH MODULES (PSM)
The T7 chassis-based OLT includes two slots for
redundant Platform Switch Modules (PSMs), which aggregate all
(non-RF) services traffic of subtended ONTs. These modules
utilize IEEE Spanning Tree protocols and Link Aggregation over
Ethernet links in multiple common topologies to provide resilient
interconnection with the distribution network.

10. PLATFORM INTERFACE MODULES(PIM)
The T7 chassis-based OLT includes eighteen
(18) slots for Platform Interface Modules (PIMs),
which may be of one type or mixed PIM models. Each
PIM provides SFP-based ports for FTTP connections
to ONTs and other customer premise equipment
through the Optical Distribution Network (ODN).

The Customer Service Excellence Standard aims to bring
professional, high-level customer service concepts into
common currency with front-line public services by offering a
unique improvement tool to help those delivering public
services put their customers at the core of what they do.
Customer Service Excellence
• Customer Insight
• Customer Segmentation
• Customer Journey
• Access Channels
• Drivers of Satisfaction
Key Concept

12. CSE is a driver of continuous improvement
CSE gives you insight into your own organisation (how customer focused are
you)
CSE gives improved understanding of customer issues (by developing
customer insight)
CSE improves relationship with and satisfaction of customers
CSE is a skills development tool building real team spirit and morale
CSE is an independent validation of achievement in customer service
The benefits of Customer Service Excellence

15. Operations & Maintenance
 The operations & maintenance is a critical part for the sustenance of a GPON-FTTx network.
 O&M requires a dedicated team 24/7 to support the services running on a GPON transport.
 Vendor O&M teams at our pre-existing customers who have deployed GPON-FTTx rigorously follow
ITIL best practices to ensure 99.95% of uptime.
